Understand the installation and use points of the inertial vibration conveyor

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. It is mainly composed of a vibration exciter, a bearing groove, a main vibration spring and a frame. Can be used to transport a variety of loose materials horizontally, gently or vertically.

   The vibrating conveyor is used for material conveying by means of reciprocating vibration of the conveying trough. It is a continuous conveying equipment of non-flexible traction members. It can transport granular or block loose materials horizontally or obliquely, and can also be used to transport powder.

   The inertial vibration conveyor is driven by the inertial excitation force generated by the inertia exciter. The inertia exciter is mainly composed of an eccentric block, a main shaft, a bearing, a bearing seat, a chute, etc., and a centrifugally varying inertial force generated by the eccentric block rotating periodically excites the chute vibration. This centrifugal inertial force is the excitation force.

   The eccentric block of the inertia exciter generates a large inertia force when rotated, and the structure is simple and compact. According to the number of spindles, it can be divided into a single-axis inertial vibration conveyor and a two-axis inertial vibration conveyor.

   Note on the installation and use of inertial vibrating conveyor：

1. Before the empty running test, check the bolts of each part, especially the anchor bolts of the vibration motor. After 4 hours of continuous operation, the bolts of each part should be tightened once again, and tightened 2-3 times within one week.

2. The rotation direction of the two vibration motors should be opposite when working.

3. When the air test is running, check whether the conveyor is running smoothly, and pay attention to the temperature rise of the vibration motor bearing. After 4 hours of continuous operation, the maximum temperature of the bearing must not exceed 75 °C.

   Inertial vibrating conveyor has the advantages of simple structure, light weight, low noise, reliable operation, no dust pollution, convenient installation and maintenance, etc. It has been widely used in metallurgy, mining, coal, building materials, chemical, food and other 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.   

5. There is a safety cover at the size of the V-belt drive. After the inspection, the protective cover should be installed in time to prevent danger. 

       The vibrating conveyor has the advantages of simple structure, convenient installation and maintenance, low energy consumption, no dust overflow and low noise. It is widely used in the transportation of powder and granular materials in metallurgy, coal, building materials and other industries.

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.
