A closed pickling device for metal parts

Abstract

The invention relates to the technical field of treatment devices, in particular to a closed-type treatment device for metal pieces. The closed-type treatment device is provided with a shell. A sealing cover is hinged to the upper end of the shell. The lower end of the shell is fixedly arranged through supporting columns. A rotating rod is perpendicularly arranged in the shell in an inserted mode.A plurality of hanging rods are perpendicularly arranged on the rotating rod in the length direction. The upper end of the rotating rod penetrates out of the sealing cover and then is fixedly connected with a driving motor. The two sides of the driving motor are fixed to a fixing plate through an embracing hoop. A feeding opening is formed in the upper end of the shell. A conical discharging opening is formed in the middle of the lower end of the shell. According to the closed-type treatment device for the metal pieces, corrosion to other equipment by volatilization of acid liquid can be avoided, waste of the acid liquid is reduced, quick surface treatment of the metal pieces is ensured, the treatment time is shortened, and the treatment efficiency of the whole device is improved.

Description

Technical field [0001] The invention relates to the technical field of processing devices, in particular to a closed pickling device for metal parts. Background technique [0002] With the continuous development of society, the mechanical processing industry has developed rapidly. In the machining industry, there are many ways to process products, such as turning, milling, grinding, polishing or surface treatment. Surface treatment is to pickling, phosphating, polishing, and spraying the surface of the product. Plastic or spray paint can guarantee the surface quality of the product. At present, the pickling and phosphating equipment used for the surface treatment of metal parts adopts an open structure. After long-term use, it is found that the acid in the pickling and phosphating equipment will volatilize, which will cause serious corrosion of other equipment and also require Operators frequently add acid to increase the concentration, which is troublesome to operate.
