Intelligent control system for spiral cloth feeder

Abstract

The invention discloses an intelligent control system for a spiral cloth feeder. The system comprises a material information collection assembly, an A / D conversion module, a communication module, a man-machine interface, a driver, a PLC, a frequency converter, a remote control terminal and a protection module. The system is scientific and reasonable, use is safe and convenient, a 3D lattice type laser radar serves as an information collecting component, material input the spiral cloth feeder on a roller sieve can be detected in real time, information collected for detection is operated by thePLC, the rotating speed of the spiral cloth feeder is changed according to the quantity of material on the roller sieve, the rotating speed is proportional to the quantity of materials, the system reduces the rotating speed of the feeder automatically when the feeding quantity is low, a driving power provided for the spiral cloth feeder is reduced, and energy is saved during work of the feeder.

Description

technical field [0001] The invention relates to the technical field of intelligent control systems, in particular to an intelligent control system for a screw feeder. Background technique [0002] In the past, in the coal handling system of medium and large thermal power plants, the equipment layout of the crushing room was a belt conveyor and a roller screen in the upper layer, a large ring hammer crusher in the middle layer, a belt conveyor in the lower layer, and a screw feeder installed in the coal handling system. Between the shaft screen and the coal crusher, through the screw feeder, the coal is uniformly covered in the length direction of the rotor of the coal crusher, so as to improve the efficiency of the coal crusher and save energy. The tube enters the roller screen for screening, and the coal with qualified particle size falls directly into the belt conveyor on the lower layer through the funnel and chute under the screen. In the length direction of the coal cr...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides an intelligent control system for a spiral cloth feeder, which can effectively solve the problem that the spiral cloth feeder proposed in the above-mentioned background technology can only use high speed, and when the feeding amount of the spiral cloth feeder is small, the spiral cloth The speed of the feeder is still working at a high speed, which causes the problem of wasting part of the electric energy when the coal delivery of the screw feeder is reduced.
