Abstract

The invention relates to a pickling passivation device, in particular to a pickling passivation device for stainless steel valves. To solve technical problems, the pickling passivation device for the stainless steel valves, provided by the invention, comprises a baseplate, a left support, a right support, a working groove, a first valve, a discharging hopper, a wedge block and the like, wherein the left support and the right support are respectively connected at left and right sides of the top of the baseplate; a stirring device is arranged on the left support; a liquid feeding device is arranged on the right support; the working groove is arranged on the top of the baseplate and located between the left support and the right support; the discharging hopper is arranged at the left of the rear side of the bottom of the working groove; and the first valve is arranged on the discharging hopper. According to the pickling passivation device for the stainless steel valves, provided by the invention, the stainless steel valves are subjected to primary and secondary full pickling passivation reactions, so that the device has the effect that the pickling passivation reaction efficiency is high and the anti-corrosion capacity can be effectively increased.

Description

technical field [0001] The invention relates to a pickling passivation device, in particular to a pickling passivation device for stainless steel valves. Background technique [0002] Stainless steel valve industry: food biscuit industry, instant noodle and rice noodle industry, all kinds of quick-frozen food dehydration line equipment, glass products industry. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. The parts of stainless steel valves must be pickled and purified before assembly, and then rinsed with pure water to avoid chemical residues. This can greatly improve the corrosion resistance of stainless steel and make stainless steel valves of higher quality. [0003] At present, in the process of pickling and passivation of stainless steel valves, the reaction efficiency of pickling and passivation is low, and there are too many agents on the surface of sta...
