Roller cleaning device of belt conveyor

Abstract

The invention discloses a roller cleaning device of a belt conveyor. The roller cleaning device of the belt conveyor comprises circular-arc-shaped scrapers, the scrapers are fixed on a scraper frame, the bottom of the scraper frame is fixed on sliding blocks, the sliding blocks are arranged on two groups of sliding guide rails in a supported mode, a lead screw nut is fixed on the sliding blocks, a lead screw nut pair is formed by the lead screw nut and a ball screw, one end of the ball screw is connected with a forward-rotation and inversion motor through a coupler, the sliding guide rails are fixed on a bottom plate, a material receiving plate is arranged on the outer side of the bottom plate and below the scrapers, and a cleaning brush is arranged at the bottoms of the scrapers and the scraper frame. The roller cleaning device of the belt conveyor has the advantages of being simple in structure, convenient to operate, good in effect of ice tubercle cleaning, and good in popularization prospect, ensuring that the belt conveyor is not off tracking, and a rubber belt is even in tension at the position of a roller, ensuring that the belt conveyor can be in normal operation, and improving service life of the rubber belt and the roller.

Description

technical field [0001] The invention relates to the field of belt conveyors, in particular to a belt conveyor roller cleaning device, which can automatically clean the materials stuck on the belt conveyor rollers, especially frozen materials, and aims to solve the problem of sticking on the belt conveyor rollers. Cleaning up objects and icing to prolong the service life of conveyor belts and other accessories, eliminate unnecessary manpower consumption, save labor, time and worry. Background technique [0002] In modern industry, belt conveyors are mainly used to transport granular objects such as coal. Due to the unclean unloading, impurities often stick to the surface of the drum, especially in winter, when the weather is cold, due to rain, snow, ice or wet coal. There is a layer of frozen coal stuck on the adhesive tape surface. Part of the frozen coal is removed by the H-type and P-type belt cleaners of the belt system, but it is not easy to remove completely. As a resul...

[0002] In modern industry, belt conveyors are mainly used to transport granular objects such as coal. Due to the unclean unloading, impurities often stick to the surface of the drum, especially in winter, when the weather is cold, due to rain, snow, ice or wet coal. There is a layer of frozen coal on the adhesive tape surface. The H-type and P-type belt cleaners of the belt system remove some of the frozen coal, but it is not easy to remove it completely. As a result, when the tape passes through the reversing roller, the coal sticks to the reversing roller to form ice lumps

These ice tumors are as small as 20-30mm thick, and as large as 100-150mm thick. The harm is obvious. When the belt is running, the ice tumors will first damage the belt and directly affect the mechanical life; Wear and tear will endanger the safe operation of the equipment; the third will lead to serious slippage of the conveyor belt, which will easily cause fires in the mine

Especially in the north, when the ice tumor is large, it is impossible to work at all. It is necessary to wait for the maintenance personnel to remove the ice tumor before they can work. During the three months of winter (December-February of the next year), the maintenance personnel need to clean up 2-3 times a week, causing a lot of damage. Manpower consumption, relatively low efficiency

Chinese patent, publication number: CN201395409 has announced a kind of belt conveyor roller cleaning device, and it has certain cleaning effect to the sticky material on the roller, but in the cold weather situation in the north, it is difficult to clean the sticky ice tumor on the roller. Ideal, can't even clean up
