Electric ballasting rust remover on the inner wall of pipeline

Abstract

The invention discloses an electric impeller blasting deruster of pipe internal wall, using over all structure of electromechanical integration operating dolly type, which includes five portions of a walking system, a sealing system, an impeller blasting system, a sand sweeping system and a dedusting system, and is a special machine for automatic derusting of self sealing, self sand sweeping and self supplying sand steel tube internal wall. Comparing to prior art at home and abroad, main advantages of the deruster are that it changes the history of single establishing the derusting line for former impeller blasting deruster, and the invention can complete on-line derusting operation mating with various anti-corrosive operations, also can use alone for derusting on-scene construction, capable of realizing cycle use by adding sand at one time, with good effect and quick speed of derusting, good sealing and without environmental pollution, and the machine per se has compact structure, convenient and flexible conveying and operating, and low cost, capable of greatly reducing operation cost of derustering for steel pipe internal wall.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an electric shot blasting machine for the inner wall of a pipeline, which is mainly used for removing rust, oil and dirt from the inner surface of a pipeline-shaped object, especially the inner surface of a pipeline-shaped object of a steel material. Surface treatment of soil and other attachments. Background technique [0002] Pipes such as steel pipes and cast iron pipes are widely used in technical fields such as petroleum, chemical industry, water supply and drainage, power stations, papermaking, leather, ventilation and corrosive gas chimney extraction in my country, but steel pipes and cast iron pipes are good conductors of electricity. During storage and use, local battery reactions will occur due to chemical and electrochemical effects, and the surface is very easy to rust, which often pollutes the conveying medium. In the past, when derusting the inner wal...

Problems solved by technology

[0002] Pipes such as steel pipes and cast iron pipes are widely used in the technical fields of petroleum, chemical industry, water supply and drainage, power stations, papermaking, leather, ventilation and extraction of corrosive gas chimneys in my country. However, steel pipes and cast iron pipes are good conductors of electricity. During storage and use, local battery reactions will occur due to chemical and electrochemical effects, and the surface is easily rusted, which often pollutes the conveying medium. Therefore, special anti-rust and rust-removing treatments are often required on the surface; In the past, when derusting the inner wall of steel pipes, the shot blasting and derusting machine used needs to establish a separate derusting operation line. The equipment needs a large number of accessories such as a separate sand supply device and a sand return device, which cannot be used alone. The efficiency is low, and the structure itself is huge, the handling and operation are very cumbersome, and the price is expensive. For a long time, a lot of manpower, material resources and financial resources have been wasted in the process of derusting the inner wall of the steel pipeline.
