Automatic impurity-discharging and feeding machine

Abstract

Provided is an automatic impurity-discharging and feeding machine. The automatic impurity-discharging and feeding machine comprises a valve body, a transmission shaft, an impeller and a driving motor; a rotational speed sensor is connected to one end of the transmission shaft and transfers detected signals to a PLC, the PLC controls the driving motor to rotate positively and negatively. The automatic impurity-discharging and feeding machine can automatically discharge impurities fallen into the gap between the impeller and valve body.

Description

technical field [0001] The invention relates to an automatic miscellaneous feeder. Background technique [0002] The rigid impeller feeder is widely used in building materials, metallurgy, chemical industry, electric power and other industries, and it can also continuously and evenly transport the dry powder or small particles in the upper silo to the lower connection equipment. A conventional rigid impeller feeder is usually composed of a valve body, a drive shaft, an impeller, and a motor reducer. After electrification, the motor reducer drives the transmission shaft and the impeller to rotate, so as to achieve the purpose of ash unloading. It has the characteristics of good wear resistance of blades, high air-locking performance, thorough discharge, stable connection, uniform discharge and compact structure. However, these characteristics are guaranteed when the incoming particles are uniform and free of impurities, which requires the user to install crushing equipment ...

AI Technical Summary

Problems solved by technology

But now many users do not have crushing equipment and screening equipment at all, and often the materials pulled from the stockyard are directly poured into the hopper for production, so sometimes the materials entering the rigid impeller feeder are often There will be garbage, cloth strips, paper scraps, bark and some hard impurities

These impurity materials move with the rotation of the impeller, and sometimes the impurities will be stuck in the gap between the impeller and the valve body or the material will be too jammed in the card wheel, causing the impeller to not rotate, and the material will not work normally. It will be transported to the next level of equipment, resulting in material blockage at the position of the impeller feeder, and the resistance on the drive motor will suddenly increase, causing the drive motor to heat up. After a while, if the power has not been cut off, the drive motor will Burn out, seriously affecting the normal production operations of users
