Rotary push type casing cleaning brush

Abstract

The invention discloses a rotary push type casing cleaning brush comprising a torque tube and a soft shaft, wherein the torque tube is used for torque transfer, the torque tube and the soft shaft are in detachable connection, bristles for cleaning the inner wall of a casing are arranged at the front end part of the soft shaft and are composed of long bristles and short bristles distributed at the front end of the tube in screwed distribution for cleaning the inner wall of the casing, the other end of the soft shaft is provided with a long and thin end part arranged in match with the torque tube, and the end, provided with the bristles, of the soft tube is fixedly provided with a guide block for guiding the bristles to push forwards under the torque of the soft tube. The cleaning brush, disclosed by the invention, can clean the casing wall throughly, the dead angle can be avoided, acid and alkali cleaning fluid is not needed, corrosion and secondary pollution caused by the acid and alkali cleaning fluid on the casing can be avoided, the service life of the casing is prolonged, the reutilization of circulating water can be facilitated, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to the field of cleaning tools for common casings, in particular to a rotary pusher casing cleaning brush for effectively cleaning the casings of heat exchangers. Background technique [0002] At present, casing heat exchangers are becoming more and more popular, and the performance of casing plays an important role in the development of heat exchanger technology. Serpentine sleeves are commonly used in heat exchangers, and the cleaning of serpentine sleeves has always been a difficult problem in the industry. At present, the inner wall of the casing is mainly cleaned with acid and alkali solution and ordinary mechanical methods. The cleaning method of acid and alkali solution not only easily perforates the tube wall and causes the overall damage of the equipment, but also it is difficult for the inner wall of the cleaned casing to meet the requirements of edible standards. There is residual cleaning liquid left on the pipe wall,...
