Tower drum sand blasting and rust removing device

Abstract

The invention provides a tower drum sand blasting and rust removing device. The tower drum sand blasting and rust removing device comprises a two-way driving mechanism, crawler-type advancing assemblies, a friction rust removing mechanism, a sand blasting assembly and a sand removing assembly; the two crawler-type advancing assemblies are mounted on two power execution components in the two-way driving mechanism correspondingly; the friction rust removing mechanism comprises a planetary driving mechanism, a support, a disc, an ejector rod, a spring I, a rust removing brush and a motor I; the sand blasting assembly is arranged on a sun assembly in the planetary driving mechanism; and the sand removing assembly is arranged on the two-way driving mechanism and used for scraping out rust removing sand in a tower drum. The ejector rod is driven to move synchronously through rotation and revolution of a planetary wheel in the planetary driving mechanism, the ejector rod in the revolution state moves along the disc, the rust removing brush achieves rotation, revolution and reciprocating motion along the interior of the tower drum, and then rust removing is conducted on the tower drum in cooperation with the rust removing sand sprayed out by the sand blasting mechanism; and the rust removing brush can raise the rust removing sand for the second time when moving in the tower drum, and the rust removing effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of derusting tower tubes, in particular to a sandblasting and derusting device for tower tubes. Background technique [0002] Publication No. CN212371960U provides a sandblasting and derusting device for pipelines, which includes a sand pipe joint and a pipeline main body. The left end of the sand pipe joint is provided with a pipeline main body. The sand pipe joint and the pipeline main body are fixed by spot welding. The left end of the main body is provided with a sandblasting nozzle, and the upper and lower ends of the main body of the pipeline are respectively provided with a bracket. A telescopic frame, and the telescopic frame can be compressed under the action of pressure, so that it can better adapt to the operation of rust removal for pipelines of different sizes. [0003] The above-mentioned prior art only removes rust by means of sand blasting, so it is impossible to completely remove rust and t...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned prior art only uses sandblasting to remove rust, so it is impossible to completely remove rust and the effect of rust removal is not good in areas facing thicker rust layers.
