Deep rust removal equipment for outer surface of steel pipe

Abstract

The invention discloses deep rust removal equipment for the outer surface of a steel pipe. The deep rust removal equipment for the outer surface of the steel pipe comprises a chemical rust removal device and a mechanical rust removal device, wherein the mechanical rust removal device comprises a rotating cylinder, a rust brushing module and a rotating driving mechanism; the rust brushing module comprises at least two rough brushing modules and at least two fine brushing modules; each rough brushing module comprises a rough brushing mounting block, multiple rough brushing steel wires and two homogenizing rollers; one end of each rough brushing steel wire is fixedly connected onto the corresponding rough brushing mounting block; the other end of each rough brushing steel wire extends into an inner cavity of the rotating cylinder; each two homogenizing rollers are located on the two sides of the rough brushing steel wires respectively; each homogenizing roller is connected onto the corresponding rough brushing mounting block through an elastic telescopic structure; and each fine brushing module comprises a fine brushing mounting block and a fine brushing sand block. The deep rust removal equipment for the outer surface of the steel pipe not only can thoroughly remove rust on the surface of the steel pipe and is good in rust removal quality, but also has the advantages of being simple in structure, small in occupied space, low in cost, easy to widely apply and the like.

Description

technical field [0001] The invention relates to steel pipe derusting equipment, in particular to a steel pipe outer surface deep derusting equipment. Background technique [0002] With the continuous development of society and the continuous construction of various projects, the demand for steel pipes is also increasing, and its application has played an increasingly important role in the growth of my country's national economy. [0003] Steel pipes are corroded by air after long-term storage, and rust will appear on the outer surface. Steel pipes with rust cannot be used directly, and must be derusted before further application. However, the derusting equipment for steel pipes on the market is too simple at present. For the removal of rust on the outer surface of steel pipes, although the current technology has disclosed relatively complete methods such as "shot blasting rust removal" and "sand blasting rust removal", the rust removal equipment itself is relatively large an...

Problems solved by technology

[0003] Steel pipes are corroded by the air after long-term storage, and rust will appear on the outer surface. Steel pipes with rust cannot be used directly and must be derusted before further application. However, the derusting equipment for steel pipes on the market is too simple at present. For the removal of rust on the outer surface of steel pipes, although the current technology has disclosed relatively complete methods such as "shot blasting rust removal" and "sand blasting rust removal", the rust removal equipment itself is relatively large and the material consumption is high.

Although it can achieve a very good treatment effect, the cost of production and derusting processing is relatively high, and a special workshop is required, which is not conducive to wide application and promotion
