AI Technical Summary

Technical Problem

Existing vibrating screens only perform dust removal once during the screening process, resulting in the raw materials still containing a large amount of impurities. Furthermore, the dust collection bags are easily adsorbed by impurities, affecting the cleaning effect.

Method used

The system employs a secondary impurity removal vibrating screen system, including a support frame, a vibrating screen box, a separation box, first and second impurity removal boxes, a conveyor belt, and a control system. It performs two-stage impurity removal and dust collection through impurity removal channels and pipes, and uses bending plates and narrow opening structures to block large-sized impurities, ensuring that small particles are removed through the dust collection bags.

Benefits of technology

It significantly improves the purity of raw materials, prevents impurities from adsorbing onto the dust collector bags, extends the service life of the dust collector bags, and improves the screening effect.

Abstract

This invention discloses a secondary impurity removal vibrating screen and its control system, relating to the field of screening machinery technology. The screen includes a support frame, on which a vibrating screen housing is mounted. A separation box is mounted at one end of the vibrating screen housing. A first impurity removal box and a second impurity removal box are also mounted on the support frame. The upper end of the separation box is connected to the first impurity removal box via an impurity removal channel. A conveyor belt is mounted on the support frame, and a hopper is mounted on the separation box. The hopper and conveyor belt are correspondingly configured, and the hopper is connected to the impurity removal channel via an impurity removal pipe. This invention allows for two impurity removal operations on screened grain, thereby improving dust removal efficiency. The first impurity removal box can deposit large particles (wheat ears, wheat bran, etc.) and other impurities, preventing large particles from clogging the dust collector bags.
