Pickling tank used for steel pipe acid pickling

Abstract

The invention relates to the technical field of pickling pools, in particular to a pickling pool for pickling steel pipes, comprising a pool body, cover plates are hinged on both sides of the upper end of the pool body, and a placement plate is connected to the pool body through a sliding mechanism. And the cross-sectional area of ​​the placing plate matches the cross-sectional area of ​​the pool body, the placing plate is provided with a plurality of leakage holes, the both sides of the pool body are provided with support columns, and the space between the two support columns is The upper end is provided with a support plate, the lower end of the support plate is provided with a hydraulic rod, the middle of the two cover plates is provided with a semicircular hole, and the two semicircular holes form a circular hole, the output shaft of the hydraulic rod It is fixedly connected with the placement plate through a round hole. An acid outlet is provided on one side of the lower end of the pool body. One end of the acid outlet is connected to a water pump, and the other end of the water pump is connected to an acid guide hose. The other end passes through the cover plate and communicates with the pool body. The invention has the characteristics of thorough pickling and convenient putting in and taking out of steel pipes.

Description

technical field [0001] The invention relates to the technical field of pickling pools, in particular to a pickling pool used for pickling steel pipes. Background technique [0002] In the production process of steel, the rust spots on the surface of the steel must be removed by pickling, but the effect of pickling in the existing steel pickling pool is not ideal. If the steel is directly put into the pool, the reaction will lead to acid in different positions in the pool. If the concentration is different, the rust spots on some steel products will not be completely removed. At the same time, it is not convenient to take out the steel products. Toxic and harmful gases are likely to be produced during the cleaning process, which will affect the environment. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a pickling tank for steel pipe pickling. [0004] In order to achieve the above object, ...

Problems solved by technology

[0002] During the production process of steel, it needs to be pickled to remove the rust spots on the surface of the steel, but the effect of pickling in the existing steel pickling pool is not ideal. If the steel is directly put into the pool, the reaction will lead to acid in different positions in the pool. The concentration is different, which will cause the rust spots on some steel materials to not be completely removed, and it is also inconvenient to take out the steel materials, and it is easy to produce toxic and harmful gases during the cleaning process, which will affect the environment.
