Ash remover for inner wall of mortar pipe

Abstract

An ash remover for the inner wall of a mortar pipe comprises an external winding and unwinding machine and an internal ash scrapping frame. The external winding and unwinding machine comprises a pipe clamping machine box, a pull rope winch and an inflating pressurization machine; the pipe clamping machine box is of a closed box structure, the bottom of pipe clamping machine box is provided with a pipe clamping support and a pull rope guide pipe, the pull rope winch is installed in an inner cavity of the pipe clamping machine box and provided with a winding-unwinding pull rope, and the internal ash scrapping frame is installed in an inner cavity of the mortar pipe and comprises a casing pipe transverse moving frame and a screw-type ash scrapping rod. According to the ash remover, the internal ash scrapping frame slides to the outlet end of the mortar pipe through the action of water flow and slides to the water inlet end of the mortar pipe through the pulling force of the external winding and unwinding machine, the screw-type ash scrapping rod removes coal ash adsorbed on the inner wall of the mortar pipe in the process of sliding back and forth, and the problems that the coal ash forms ash fouling and a pipeline is blocked are prevented. Accordingly, the ash remover for the inner wall of the mortar pipe is reasonable in structure, convenient to assemble and capable of enabling the mortar pipe to smoothly convey mortar.

Description

technical field [0001] The invention belongs to a dust remover, in particular to a dust remover for a mortar inner wall. Background technique [0002] Most of the coal ash produced by the combustion of large-scale coal-fired boilers enters the flue along with the flue gas and is collected into the dry ash storage by the dust removal device. Settling tank for sedimentation and separation. Since the mortar contains more coal ash and the coal ash is easy to adsorb the inner wall of the mortar tube, after a period of use of the mortar tube, a layer of ash scale will be formed on the inner wall of the mortar tube, and the longer the time, the thicker the ash scale layer will be. The inner diameter of the mortar pipe shrinks and blocks the pipe, which affects the normal operation of the entire mortar conveying system. Contents of the invention [0003] In order to solve the problem that the inner wall of the mortar pipe in the prior art is easy to be adhering to the problem of...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problem that the inner wall of the mortar pipe in the prior art is easy to be adhering to the problem of dirt and blockage of the pipe, the present invention aims to provide a soot cleaning device for the inner wall of the mortar pipe, which includes a retractable machine outside the pipe and an ash scraping frame inside the pipe. Remove the coal ash adsorbed on the inner wall of the mortar pipe in time, so that the coal ash will not scale and block the pipe
