A super-long pipe inner wall shot blasting derusting machine

Abstract

This scheme involves a shot blasting machine for the inner wall of an ultra-long pipeline, which includes a sand storage box, a sand conveying bucket with a power motor for throwing a head, a sand conveying box, a rotating throwing head with blades, and a steel sand collecting wing in the pipe. , Power motor of sand return device, steel sand collection wing support device, steel sand collection wing recovery device, steel sand collection auger conveying mechanism, rust removal machine walking wheel, angle adjustable walking wheel support frame, dust removal induced draft fan, fan power motor The rust removal machine is equipped with an adjustable angle walking wheel. Through the rotation of the steel pipe, the straight line walking in the steel pipe can be realized. Through the control of the sand storage box and the automatic sand volume control valve, the inner wall of the steel pipe can be adjusted. In the rust removal operation, the steel grit automatic recovery device at the back end of the rust remover can collect the steel grit in the pipe and return it to the sand storage box to achieve the purpose of recycling the steel grit. , so that the rust removal of the inner wall of the pipeline is efficient, energy-saving and clean.

Description

technical field [0001] The invention relates to a shot blasting rust removal machine for the inner wall of a pipeline, mainly an ultra-long pipeline inner wall shot blasting rust removal machine, which belongs to the field of metal processing rust removal. Background technique [0002] At present, on the pipeline anti-corrosion engineering site, the rust removal of the inner wall of the batch standard pipe length steel pipe is basically carried out in the form of a production line. , or the inner wall derusting of super-standard pipe length steel pipes. For the situation where there are many types of pipe diameters and a small number of steel pipes, in order to reduce the operating cost of the production line, artificial shot peening is often used to derust the inner wall of steel pipes. The method causes high labor intensity of workers, affects workers' health and safety, low production efficiency, waste of energy, pollutes the environment, occupies a large workplace, and h...

[0002] At present, on the pipeline anti-corrosion engineering site, the rust removal of the inner wall of the batch standard pipe length steel pipe is basically carried out by means of a production line. , or the inner wall derusting of super-standard pipe length steel pipes. For the situation of many types of pipe diameters and small number of steel pipes, in order to reduce the operating cost of the production line, artificial shot peening is often used to derust the inner wall of steel pipes. The method causes the labor intensity of the workers to be high, affects the health and safety of the workers, the production efficiency is low, wastes energy, pollutes the environment, occupies a large workplace, and the economic cost of comprehensive derusting is high; As far as the current production line is concerned, it is difficult to satisfy the rust removal on the inner wall of steel pipes over 13 meters long. If the production line is modified, it will cost a lot of money and occupy a lot of space
