Stock bin discharging device

Abstract

The invention relates to a stock bin discharging device. The device comprises a platform, a feeding machine arranged below the platform and a bar valve arranged on a feeding port in the top of the feeding machine, and further comprises a stock bin and a material monitoring device, wherein the stock bin is movably arranged in the platform through a plurality of spring supports, and an opening in the bottom of the stock bin is flexibly inserted into the feeding port in the top of the feeding machine and arranged above the bar valve. According to the device, the material running condition of the feeding machine can be automatically monitored and judged by means of the change of the distance between a material detection plate and a position sensor, and after material blockage occurs, each vibrator and each air cannon are automatically started to quickly and timely eliminate the material blockage phenomenon; 24-hour guarding monitoring of personnel is not needed, so that the labor intensity is greatly reduced and the labor cost is reduced; and the time for finding material blockage and the time for recovering discharging are greatly shortened, the hysteresis is eliminated, the material breaking time of the feeding machine is shortened, and the production continuity is guaranteed.

Description

technical field [0001] The invention relates to a feed bin unloading device. Background technique [0002] In the cement raw material processing section, the material in the silo is sent to the next process through the feeder. When the moisture content of the material is high, the silo will be arched, which will prevent the material from entering the feeder. Therefore, it is necessary to patrol The inspectors check the unloading situation in real time, and manually start the rapping device or the air cannon blowing device to dredge the material when encountering the above-mentioned problems. When the material is not smooth, the rapping process will instead vibrate the material in the silo, resulting in poorer material fluidity; in addition, the method of manual real-time inspection requires personnel to be on duty for 24 hours to monitor, which is labor-intensive and costly. It is also not easy to find out in time, there is a certain hysteresis phenomenon, and it is easy to...
