Installation and maintenance requirements of long distance vibration conveyor
Long-distance vibration conveyors are also called horizontal vibration conveyors, high-temperature vibration conveyors, etc. They are continuous conveying machines that use a vibrator to vibrate the trough, thereby sliding or throwing the materials in the trough along a certain direction. This equipment is a highly versatile and advanced structure high temperature material vibration conveying equipment.
The working principle of the long-distance vibration conveyor is to use two vibration motors as the excitation source. Using the principle of self-synchronization, the two vibration motors rotate in the opposite direction to cause the reciprocating vibration of the balance frame at the bottom of the conveyor. The role of the drive the vibration of the upper conveying trough, so as to achieve the purpose of conveying materials.
There are two types of long-distance vibrating conveyors: open type and closed type。
Basic requirements for installation and maintenance of long distance vibration conveyors：
(1) The bottom frame and the tank of the vibration conveyor must be installed straight. It is recommended that the flatness is 10 meters and the length is not greater than 5-8 mm。Excessive deflection of the bottom frame and the tank will cause greater installation stress. , Which in turn will cause early damage to these parts。
(2) In order to meet the above requirements, the lower surface of the vibration isolation spring should have close to the same elevation, and its tolerance should not be greater than 5-8 mm.
(3) The installation angle of the guide rod of the vibration conveyor should be close to the same, the shear spring should be perpendicular to the guide rod, and the tolerance of its installation angle to its nominal installation position is + -1.
(4) The transmission shaft is perpendicular to the center line of the groove body. The two transmission links should be parallel to each other without excessive skew. The tolerance of the installation angle is + -1. After the installation, the transmission shaft should be flexible and can be moved by hand 360 or more.
(5) All screws of the vibration conveyor should be locked. Generally, spring washers should be added, and double nuts can also be used to lock. Otherwise, the bolts will loose quickly and affect the normal operation of the machine.
The long-distance vibration conveyor is mainly used for conveying materials such as powder, granular, block and mixed products. It is widely used in building materials, metallurgy, chemical industry, coal mining, machinery manufacturing, coal, tobacco, food, medicine and other industries.

Advanced Physical Extraction Technology-Supercritical fluid extraction
Supercritical fluid extraction (SFE) is the most advanced physical extraction technology in the world. At lower temperatures, when the pressure of the gas increases continuously, the gas will be converted into liquid. When the temperature increases, the volume of the liquid will increase. There is always a critical temperature (Tc) and a critical pressure (Pc) for a particular substance. When the temperature and the critical pressure are higher than the critical temperature and the critical pressure, the substance will not become liquid or gas. It's the critical point. In the range above the re-critical point, the material state is between gas and liquid, and the fluid in this range becomes supercritical fluid (SF).
Supercritical fluids have strong penetration capacity similar to gases and high density and solubility similar to liquids. They have good solvent properties and can be used as solvents for extraction and separation of monomers. Supercritical fluid extraction (SFE) is a new and high technology in modern chemical separation. SFE combines traditional distillation with organic solvent extraction and effectively separates, extracts and purifies the matrix and extract by using supercritical CO2 as a solvent.
CO2 is a safe, non-toxic, cheap liquid. Supercritical CO2 has similar gas diffusion coefficient, liquid dissolving force, zero surface tension, can quickly penetrate into solid substances, extract its essence, and has the characteristics of high efficiency, no oxidation, pure nature, no chemical pollution and so on. Supercritical fluid extraction separation technology uses the solubility of supercritical fluid to be closely related to its density. By changing pressure or temperature, the density of supercritical fluid can be greatly changed. In the supercritical state, the supercritical fluid is contacted with the substance to be separated, so that the components with different polarity, boiling point and relative molecular mass can be extracted selectively.
When extracting natural products by supercritical fluid extraction, CO2 is usually used as extractant. This is because:a)
(a)The critical temperature and critical pressure are low (Tc=31.1 C, Pc=7.38MPa), the operating conditions are mild, and less damage to the effective components, so it is especially suitable for the treatment of high boiling point heat sensitive substances, such as essence, spices, oils, vitamins, etc.
(b) CO2 can be regarded as a non-toxic and cheap organic solvent similar to water;
c) CO2 is stable, non-toxic, non-combustible, safe and non-polluting in use, and can avoid oxidation of products; d) the extract of CO2 contains no nitrate and harmful heavy metal, and there is no residual harmful solvent;
e) CO2 is extracted in supercritical CO2 extraction. The extracted material can be precipitated by lowering pressure or raising temperature without repeated extraction operation, so the supercritical CO2 extraction process is simple. Therefore, supercritical CO2 extraction is especially suitable for the extraction and purification of biology, food, cosmetics and drugs.

Points of attention for vibration conveyors during installation and construction
Description:
The vibrating conveyor is a continuous conveying machine without a traction member. It uses the principle of mechanical resonance to transport materials. The vibrating conveyor is mainly composed of a bearing member, an elastic member, an exciter, and the like. The power source of the drive mechanism of the vibrator foot vibration conveyor is used to generate an exciting force to cause continuous vibration of the bearing groove. The magnitude of the exciting force directly affects the amplitude of the load, and its alternating frequency is the operating frequency of the conveyor.
The carrier is a trough-shaped or tubular vibrating trough. During the vibration process, energy is transferred to the material to make a continuous throwing motion along the conveying direction. The carrier is a vibrating body and needs to have sufficient rigidity and strength. The vibration-damping support device is both a support device for the whole machine and a vibration-damping device.
So what are the problems that should be paid attention to during the installation and construction of the vibrating conveyor? See the following points for details:
1、 Handle gently during transportation to avoid deformation of components;
2、If problems are found during the test run, they should be stopped for treatment;
3、bracket welding should pay attention to the welding sequence, reduce welding deformation;
4、Bonding work should be carried out in a well ventilated place;
5、 tape cutting tools should have depth control fixtures;
6、disable open flames;
7、 the environment should be dustproof.
The relevant knowledge points of the vibrating conveyor introduced above are hoped to be helpful to everyone's work.

Description:
Horizontal vibration conveyor is a device for transmission and transportation. In actual operation, the vibration-damping bearings of the vibration conveyor are frequently damaged, the supporting spring is easily deformed, and the equipment vibration frequency is too fast, which seriously affects the continuous and stable operation of the device.
The company's technical department combined years of operating experience, analyzed the fault, proposed specific solutions, received practical results, and ensured the long-term stable operation of the device.
vibrating conveyor
一、Failure Analysis
1. Equipment level, vibration-absorbing bearing installation abnormal
(1) When the equipment is installed and debugged, the level is not good, and the installation standard is not reached, which causes the equipment to be polarized and unevenly stressed, which causes the material transportation trajectory to shift, the vibration-damping bearings, plate springs, and support springs to be abnormally damaged. Causes the transport body to crack.
(2) When installing vibration-damping bearings, the mounting angles of the two bearings are not consistent, the vibration period is uneven, and the excitation force distribution is uneven, resulting in abnormal wear of the vibration-damping bearings.
2. Loose anchor bolts or other fasteners
(1) There were omissions during installation and commissioning, and the anchor bolts became loose again, and they were not dealt with in time.
(2) The leaf spring is broken or the fixing bolts are loose and have not been replaced or tightened in time.
3.The equipment vibration frequency is too fast
The horizontal vibration conveyor relies on a motor to drive the crank link mechanism. The motor frequency directly determines the equipment amplitude and frequency. The motor frequency is too fast, which exacerbates the wear of spare parts and seriously affects the equipment operating cycle.
4. Support spring deformation
The device has 12 support springs to support the device body. After long-term use, individual springs are plastically deformed, causing the spring to fail, causing uneven force on the device, causing abnormal vibration of the device, and abnormal wear of the vibration-damping bearings.
horizontal vibration conveyor
二、the fault solution
(1) Adjust the level of the installation equipment so that the base of the whole machine and the base plane remain horizontal. The tolerance is 0.1 m / 1/1 000 m.
(2) All anchor bolts and components are installed and fastened as required, and the damaged leaf spring is replaced.
(3) On the premise that the equipment's conveying capacity meets the production requirements, the frequency conversion motor is used to reduce the motor frequency and reduce spare parts wear.
(4) Measure the original length of the support spring and measure the compression after installation. The deviation is less than 0.5 mm. If the deviation is too large, replace it as a whole.
The reasons for the failure of horizontal vibration conveyors are complex, sometimes the result of multiple factors. Reasonably analyzing all aspects of the equipment's failure, formulating scientific solutions, and continuously improving the operating conditions of the equipment can ensure long-term equipment operation.

Structural form of elastic connecting rod vibration conveyor
Description:
The elastic link type vibrating conveyor is a kind of highly practical vibrating conveyor. The machine has smoothness and reliability in the vibration state, and is especially suitable for long-distance transportation. The elastic link type vibration conveyor has the characteristics of low frequency and large amplitude.
The elastic flail type vibration auxiliary conveyor is composed of a conveying trough, an exciter, a transmission mechanism, a supporting component and a shock absorption system. The exciter generates a periodic vibration force under the drive of a motor, and transmits it to a conveying trough through a transmission mechanism. The conveying trough generates a periodic linear vibration at the same vibration frequency of the excitation source under the pulsation of the excitation source. At a certain throwing angle with the conveying direction of the conveying trough, the material in the trough continuously jumps and moves forward along the conveying surface of the trough under the force of forced vibration.
The elastic link conveyor is a near-resonance type vibration machine. It uses the rotation of an eccentric shaft to drive the reference tank to achieve linear reciprocating movement by driving the connecting rod and the main vibration spring to achieve the purpose of material transportation. This vibration conveyor has a wide application range and strong adaptability.
The basic structure of the elastic connecting rod vibration conveyor:
When the elastic link type vibration conveyor is used as a dual mass, its structure is composed of a slot body (upper mass), a frame (lower mass), a main vibration spring, a vibration isolation spring, a support spring, and a support pendulum (also known as a guide Connecting rod), driving connecting rod, eccentric shaft, and motor, pulley and triangle tape.
The trough body and the bracket are respectively supported by a rigid support pendulum and a support spring, and the main vibration spring, the eccentric shaft, and the driving link are connected to form an excitation force source assembly. Duplex structure.
When a vibrating conveyor with a dual mass structure works, the two masses move in opposite directions; the two inertial forces can be relatively balanced, and in actual design and production applications, the mass of the two masses is constantly changing and it is difficult to be completely equal . In material transportation, the mass of the upper mass continuously changes and cannot be balanced with the mass of the lower mass. It will still cause most of the unbalanced inertial force to be transmitted to the foundation. Therefore, the bearing capacity of the foundation should be further balanced to reduce vibration The use of lower masses and weights to balance the inertial force, or the rigid treatment and structural arrangement of the vibration isolation springs, reduces the dynamic load transmitted to the foundation, and balances the vibration of the entire mechanism. The mass should be slightly greater than the sum of the mass of the tank and the weight of the material, so that the operation of each vibration conveyor mechanism is normal.
The vibration conveyor has a simple structure, low energy consumption, less lubrication points and wearing parts, and convenient maintenance. This equipment can be widely used in powder and granular material transportation in metallurgy, coal, building materials, chemical industry, glass, electric power, machinery, food and other industries.

By using the balance body as the transport tank body, the upper and lower tanks can be transported at the same time, and the effect of using two conveyors can be produced without increasing equipment and space. A screen is installed in the conveying tank to realize the classification of the material while conveying.
Features:
In addition to the advantages of the double-body resonance type, the PSL fully balanced vibration conveyor has the most outstanding advantage that the inertial vibration force (dynamic load) transmitted to the foundation is very small and the noise is low. It is suitable for longer distances and wider slots. Wide conveyor requirements, when installed on floor slabs or steel frame supports, have the unmatched damping advantages of other types of vibrating conveyors.
Structure:
1. Conveying trough; 2. Balance frame; 3. Underframe; 4. Eccentric linkage drive; 5. Resonant spring; 6. Elastic pendulum device; 7. Damping spring; 8. Damping seat.
Principle:
The fully balanced vibrating conveyor adopts a unique elastic support type, which makes the conveying trough body and the balance body form a double-mass resonance system with completely balanced mass. The two mass bodies are connected by a resonant coil spring and an elastic guiding pendulum. Under the action of the vibration exciter, a resonance system is formed with the balance body, and the inertial vibration force generated by the resonance system is substantially canceled in the system; the equipment support chassis is coupled with the installation foundation through the spring isolation system, and can be reduced again due to the tank body. Unbalanced vibrations caused by changes in material flow, so the dynamic load on the equipment is very small.
Application:
PSL fully balanced vibrating conveyor is suitable for many industries including biomass, recycling, pellet manufacturing, sawmill, plywood, OSB, food processing, and agricultural industries.

Description:
A vibrating conveyor is a continuous conveying machine that uses a vibrator to vibrate a trough so that the material in the trough slides or is thrown in a certain direction.
Simply put, a vibrating conveyor is a device that continuously transports material by means of vibration. It is mainly composed of a vibration exciter, a bearing groove, a main vibration spring and a frame. Can be used for horizontal, gentle tilting or vertical transport (rising along the spiral groove) of various loose materials.
The vibrating conveyor can be divided into two types: horizontal conveyor and vertical conveyor according to the direction of conveying materials. According to the different driving methods, it can be divided into three types: electromagnetic vibrating conveyor, inertial vibrating conveyor and eccentric connecting rod vibrating conveyor.
Frequent maintenance and maintenance of the vibrating conveyor can increase the service life and reduce the failure rate. Specific requirements are as follows:
1. Due to the vibration transmission of the vibrating conveyor, the coupling may be loosened. Although elastic washers are added during installation, in order to avoid loosening, the operator should always check the equipment and tighten it if it is loose.
2. Operating parts, such as bearing housings and tie rod housings, with grease fittings on the outside. Each class should be filled with calcium-based or lithium-based grease to ensure lubrication and normal operation of the running parts. 3. If an operator finds an abnormality during work, he should stop the inspection in time to eliminate the fault.
4. Always check the bearing for damage. If it is found damaged, replace the new bearing of the same type in time.
