How to improve the structure of electromagnetic vibration feeder frame?

Electromagnetic feeder vibration It is widely used in the transportation of materials in many industrial fields such as mining, metallurgy, coal and so on. In the feeding process of the feeder, its frame is almost closed, and the problem of insufficient feeding quantity is easy to occur in use. Therefore, it is necessary to improve the structure of electromagnetic vibration feeder frame.

 Electromagnetic vibration feeder

When the vibrating feeder is working, the energy provided by the vibration exciter is mainly consumed in the following parts: the energy consumed by the vibration of the feeder frame; the energy consumed by the deformation of the feeder frame during the vibration; and the energy consumed by the material vibration. According to the law of conservation of energy, reducing the vibration parameters of the frame and enhancing the stiffness of the frame can increase the energy consumed by the vibration of the material, and then increase the speed of the material movement, so as to increase the feed rate of the material.

Structural improvement methods

The overall lightweight of the frame can reduce the vibration parameters of the frame and improve the energy utilization rate. However, reducing the steel plate will reduce the stiffness of the frame and increase the energy consumption of the frame deformation. Therefore, the overall lightweight of the frame is not feasible.

As the overall weight reduction of the frame is not feasible, the structure of the machine can be improved to a split structure with bottom plate vibration and upper frame not participating in vibration, so as to reduce the vibration parameters. The improved frame structure is shown in Figure 2 (the original frame structure is shown in Figure 1), which is divided into upper frame and bottom plate. The upper frame is connected with the bottom plate by soft connection. The upper part of the bottom plate is welded with a "door" shaped convex steel plate, and the upper frame is opened with a "door" shaped groove. The concave convex fit forms a simple labyrinth seal.

The improved upper frame is basically unchanged to ensure the interface size of discharge and feed. The lower part of the frame is hollowed out for easy separation. The flexible connection between flange and feed end is changed to rigid connection, and the connection between elliptical flange and discharge end is still flexible. After the improvement, because the discharge port does not participate in vibration, in order to ensure smooth discharge, the discharge angle of the outlet is increased from 6 ° to 15 °. The feeding base plate is designed as a box type, which ensures the stiffness of the bottom plate when it vibrates by taking advantage of the good rigidity of the box structure. The vibration exciter seat and vibration isolation spring seat keep the original size and shape.

After the improvement of the vibration feeder, the actual operation shows that the feeding amount meets the production requirements, and the equipment runs well. Therefore, it is proved that the above-mentioned improvement method is correct and has certain popularization and application value.
