Abstract

The invention relates to an ore overflowing detection alarm device during mine belt conveying. The alarm device comprises a contact type belt deviation ore overflowing detection alarm device, a rotation stopping type material level switch ore overflowing detection alarm device, a lever principle proximity switch ore overflowing detection alarm device and a control device, wherein the control device is used for controlling the contact type belt deviation ore overflowing detection alarm device, the rotation stopping type material level switch ore overflowing detection alarm device and the leverprinciple proximity switch ore overflowing detection alarm device. According to the ore overflowing detection alarm device during mine belt conveying, belt conveying is stopped immediately when ore overflowing occurs, and meanwhile an alarm signal is sent out, so that the problems existing in the prior art are solved.

Description

technical field [0001] The invention relates to an alarm device, in particular to an alarm device for detection and alarm of overflowing ore conveyed by a mine belt, and belongs to the technical field of electric automation intelligent control. Background technique [0002] The main purpose of the belt conveyor is to carry objects and transport materials. Conveyors are able to work in both horizontal and inclined directions and can transport powdery, granular, lumpy and finished objects. Belt conveyors are widely used in coal, mining, metallurgy, building materials, light industry, chemical industry and other industries. They have the advantages of high conveying strength, low energy consumption, easy maintenance and low use cost. However, it is precisely because of the high conveying strength of the belt conveyor that it is prone to failure. The concentrator of Meishan Mining Branch has more than 5,000 meters of conveyor belts. The overflow of the belt conveyor is a commo...
