Type

Mechanical vibrating conveyor and Electromagnetic vibrating conveyor.

The mechanical type vibrating conveyor can be divided into elastic link type and inertia type; according to the number of participating vibration members, it can be divided into three types: single mass, double body and multi-body.

Single-body vibrating conveyor: only the trough produces vibration, so the vibration force is transmitted to the foundation, which is mostly light;

Double-body vibrating conveyor and multi-body vibrating conveyor (fully balanced vibrating conveyor): In addition to the trough, there are also counterweights participating in the vibration, the structure is slightly complicated, but the vibration force on the foundation can be basically eliminated, and The resonance principle is used to minimize the required excitation force.

Dynamically balanced vibrating conveyor

Vibrating Conveyor
Dynamically balanced vibrating conveyor
  • Fully balanced
  • No external balance beams
  • Adjustable stroke/variable speed
  • Eccentric drive shaft
  • PSL Dynamically balanced vibratory conveyor is developed on the basis of the plastid resonance type of a new type of vibrating conveyor
  • Besides has the advantages of the plastid resonance type
  • The most prominent advantage is passed to the base of inertial vibration (dynamic load) is very small
  • Low noise, suitable for long, wide groove width of transport requirements, when the floor surface or on steel structure installation with other type of vibrating conveyor incomparable shock absorption edge.

    Vibration Conveyor

    Elastic link type vibrating conveyor: It consists of an eccentric shaft, a connecting rod, a connecting rod end spring and a trough. Eccentric shaft rotation

    The end of the rod reciprocates to excite the trough for directional vibration. The material in the tank is continuously moved forward. Low frequency, large amplitude or medium frequency and medium amplitude are generally used.

    Electromagnetic vibrating conveyor: It consists of iron core, coil, armature and trough. When the rectified current passes through the coil, a periodically varying electromagnetic attraction is generated, which causes the chute to vibrate. Generally, high frequency and small amplitude are used.

    Inertial vibrating conveyor: It consists of an eccentric block, a main shaft, a chute, etc., and the centrifugal inertial force generated when the eccentric block rotates excites the chute vibration. Medium frequency and amplitude are generally used.

    Discription:

    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.

    Generally used for horizontal transportation, the productivity is less than 150t / h, the conveying distance is less than 80m, and the productivity decreases with the increase of the inclination angle when the vehicle is tilted.

    In addition to some parts of the vibration mechanism, there are few relative rotating parts, simple structure, can transport materials of various sizes, and can carry out closed transportation of hot, flammable, explosive, toxic and dusty materials. Process operations such as screening, dewatering, and cooling can be performed simultaneously during transportation.

    However, it is not advisable to transport sticky materials.

    Principle

    The vibrator of the vibrating conveyor vibrates the trough, and the trough body is subjected to directional forced vibration under the constraint of the main vibrating spring.

    When the tank body vibrates forward, the moving energy is transmitted to the material by the friction between the material and the tank body, so that the material accelerates, and the moving direction of the material is the same as the vibration direction of the tank body.

    When the tank body vibrates backwards, the material will continue to move forward due to the inertia, and the tank body will move backwards from the bottom of the material. Due to the resistance during the movement, the material will fall over the tank body and fall back to the tank body.

    When the tank vibrates again forward, the material is transported forward due to acceleration. This cycle is repeated to achieve material transport.

    Structure:

    Conveyor and balance chassis

    The trough (carrier, trough) and balance chassis (chassis) are the two main components in the vibrating conveyor system. The tank conveys the material, and the bottom frame mainly balances the inertial force of the tank body and reduces the dynamic load transmitted to the foundation.

    Exciter

    The vibration exciter is the power source of the vibrating conveyor and the exciting force that generates periodic changes, and the components that continuously vibrate the trough and the balance chassis can be classified into mechanical type, electromagnetic type, hydraulic type and pneumatic type. The magnitude of the exciting force directly affects the amplitude of the trough.

    Main vibration spring and vibration isolation spring

    The main vibration spring and the vibration isolation spring are elastic elements in the vibrating conveyor system. The role of the main vibration spring: the main vibration spring supports the trough, usually inclined installation, the oblique inclination angle is ß (vibration angle), its role is to make the vibrating conveyor have a suitable near resonance working point, which facilitates the mutual transformation of the kinetic energy and potential energy of the system. , effectively use vibration energy. The role of the vibration isolating spring: support, and can reduce the dynamic load transmitted to the foundation or structural frame.

    Guide rod

    The function of the guiding rod is to make the groove body and the bottom frame vibrate relative to each other perpendicular to the center line of the guiding rod, and it is connected with the groove body and the bottom frame through a rubber hinge.

    Feeding device and unloading device

    Feeding device and unloading device are used to control material flow, usually softly connected to the tank
