Coal chute clearing tool and mounting method

Abstract

The invention provides a coal chute clearing tool comprising a pipe body, a clearing piece arranged at the tail end of the pipe body, and a handle arranged at the head end of the pipe body. The clearing piece is in a flat shovel shape, and one end of the clearing piece is provided with a mounting hole. The handle is in a linear shape. The pipe body and the clearing piece as well as the pipe body and the handle are connected in a welded mode. The coal chute clearing tool is portable in hands, the clearing piece is in the flat shovel shape and is easily inserted into the coal-accumulating part,and the clearing piece can use local materials; and when accumulated coal blocks the clearing piece, the linear handle is rotated, thus tool damage can be avoided, and the blocked coal inside a coal chute is conveniently and quickly cleared.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning tools, and in particular relates to a coal falling pipe cleaning tool and an installation method. Background technique [0002] The coal falling pipe is the channel connecting the material line of the coal conveyor belt. It is usually composed of a material hopper, a three-way baffle, an inclined pipe, an air lock, etc. The phenomenon of coal blocking in the coal falling pipe often occurs. After repeated observation and analysis, It was found that the main part causing coal blockage was the joint between the tee baffle and the inclined pipe, especially the upper part of the inclined pipe. Since most of the inclined pipes used in the coal transportation channel are made of ordinary carbon steel, the inner wall of the pipe is easy to corrode, and the surface Roughness will cause coal powder to accumulate on its surface, which will increase the resistance of coal transportation. When the am...

[0002] The coal-falling pipe is the channel connecting the material line of the coal conveyor belt. It is usually composed of a material hopper, a three-way baffle, an inclined pipe, and an air locker. The phenomenon of coal blocking in the coal-falling pipe often occurs. After repeated observation and analysis, It was found that the main part of the coal blockage was the joint between the tee baffle and the inclined pipe, especially the upper part of the inclined pipe. Since most of the inclined pipes used in the coal conveying channel are made of ordinary carbon steel, the inner wall of the pipe is easily corroded, and the surface Coarse, causing coal powder to accumulate on its surface, which in turn increases the resistance of coal conveying. When the amount of coal is slightly larger, it will cause instantaneous fluff and blockage.

In the prior art, due to some long coal drop pipes, most of the tools used are iron coal drills, which are too heavy to handle and difficult to operate
