Fully-automatic sealed acid-circulation pickling tank

Abstract

The invention discloses a fully-automatic sealed acid-circulation pickling tank, comprising a pickling tank body and a steel pipe pickling rack. The inner walls of both sides of the pickling tank aresymmetrically fixed with two fixture blocks; and buckles are arranged at the corresponding positions of the two sides of the steel pipe pickling rack. According to the invention, through clamp connection of the buckles and the fixture blocks, an eccentric wheel rotates under the driving of a driving device, so a fixed mount is allowed to shake so as to realize stirring of a pickling solution in the pickling tank, and thus, the layering of the pickling solution is prevented, and the phenomena of excessive pickling and insufficient pickling are avoided; an elastic limit device is fixed on the fixed mount and can limit steel pipes to prevent the disengagement of the steel pipes during shaking; the position of a limit rod can be adjusted through clamp connection between a limit member and a limit hole, so steel pipes of different internal diameters can be mounted and fixed; and steel pipes do not contact with each other, so the surfaces of the steel pipes are totally immersed in the pickling solution, which enables pickling efficiency to be improved.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing equipment, in particular to a fully automatic sealed acid liquid circulation pickling pool. Background technique [0002] When the stainless steel pipe is made from a billet, the surface will be covered by O in the air 2 Oxidation produces a black and yellow tight oxide layer. In order to improve the appearance and corrosion resistance of stainless steel, the processed stainless steel pipe must be pickled. [0003] There are generally two types of pickling pools used in the stainless steel pipe industry, trench type or floor type. The trench type pickling pool is not easy to find because it is buried in the ground. After the pickling pool is broken, the acid will seep into the ground and cause pollution. Surface, floor type pickling pool is pickling, the steel pipe is mainly soaked in the pickling solution, so that the surface of the steel pipe is in direct contact with the pickling...

[0003] There are generally two types of pickling pools used in the stainless steel pipe industry, trench type or floor type. The trench type pickling pool is not easy to find because it is buried in the ground. After the pickling pool is broken, the acid will seep into the ground and cause pollution. Surface, floor type pickling pool is pickling, the steel pipe is mainly soaked in the pickling solution, so that the surface of the steel pipe is in direct contact with the pickling solution, so that a chemical reaction occurs to remove the oxide layer on the surface of the steel pipe, but the existing Most of the steel pipes are directly piled up in the pool. The direct accumulation of steel pipes and steel pipes will cause part of the surface of the steel pipes to be unable to contact the pickling solution, resulting in poor pickling efficiency, and the pickling solution will be layered after a long time, making the lower part of the pickling solution higher concentration. , resulting in some steel pipes being over-pickling and some under-pickling. For this reason, we propose a fully automatic sealed acid circulation pickling pool
