A pickling device for stainless steel parts

Abstract

The invention relates to the technical field of processing stainless steel parts, and discloses a pickling device for stainless steel parts, which includes an injection cylinder, side frames are inserted into the left and right inner walls of the injection tube, and elastic stretch pads are fixedly connected to the front and rear inner walls of the side frames. The corresponding end of the elastic expansion pad corresponding to the front and back is fixedly connected with a slide plate, and the top surface of the injection cylinder is fixedly connected and communicated with three infusion tubes, and the left and right infusion tubes correspond to two infusion tanks respectively, through the setting of the collar , the collar can be automatically deformed into two states during pickling and cleaning, wrapping the stainless steel parts during pickling, increasing the range of pickling, and using the wrapping effect of the collar to reduce the rate of acid solution detaching from the stainless steel parts, In order to achieve the benefit of saving resources, the collar is unfolded on the stainless steel parts during cleaning, thereby forming a spray effect during cleaning, and using the height difference to increase the effect and strength of water hitting the stainless steel parts, thereby increasing the cleaning effect.

Description

technical field [0001] The invention relates to the technical field of stainless steel parts processing, in particular to a pickling device for stainless steel parts. Background technique [0002] Pickling is a method of removing oxide scale and rust on the surface of steel by using an acid solution, which is called pickling. is a method of cleaning metal surfaces. Usually carried out together with the pre-filming, the acid solution needs to be applied to the outer wall of the stainless steel parts, and in order to improve the efficiency and avoid harming the user, it is necessary to use a pickling device for the stainless steel parts. [0003] The existing patent number CN1683593A proposes a pickling equipment with high production efficiency in the pickling process, which can reduce the particles contained in the pickling liquid, especially reduce the pickling generated during the pickling of various silicon steel plates The SiO2 particles in the liquid can be operated fo...

[0003] The existing patent number CN1683593A proposes a pickling equipment in pickling with high production efficiency as follows, which can reduce the particles contained in the pickling solution, especially reduce the pickling produced during the pickling of various silicon steel plates The SiO2 particles in the liquid can be operated for a long time and the maintenance cycle can be extended. It is equipped with a pickling tank for pickling the steel plate material by passing through it sequentially, and a cycle for circulating the pickling solution in the pickling tank. The pickling equipment of the path is characterized in that multiple ultrasonic waves of different frequencies are irradiated to the pickling liquid circulating in the circulation path, and particles of different particle sizes are aggregated and precipitated at each frequency, but it is When pickling the outer wall of the tubular stainless steel part, the outer wall of the stainless steel part cannot be fully contacted with the acid solution, and the rate of pickling liquid flowing out through the outer wall of the tubular stainless steel part will be faster, and the contact time between the acid solution and some areas of the stainless steel part is shorter , affecting the effect and scope of pickling

[0004] The existing patent number CN106521532B proposes a closed pickling device, which can effectively collect acid mist, ensure the safety of workers, avoid equipment corrosion, and can also solve the problem that aluminum metal workpieces cannot be neutralized with lye after pickling , in order to achieve the above object, the basic scheme of the present invention is: a closed pickling device, comprising a pickling tank with an open upper end, also comprising an acid mist treatment device and an inert gas filling device; the opening of the pickling tank is provided with a cover; The pickling tank is provided with a liquid inlet, the top of one side of the pickling tank is provided with a vent pipe connected with the pickling tank, and the upper part of the other side is provided with an exhaust pipe connected with the pickling tank. The bottom is connected with a drain pipe; the inlet pipe is provided with a first valve, and the inlet pipe is connected with the inert gas charging device; the exhaust pipe is provided with a second valve, and the exhaust pipe is connected with the acid mist treatment device; The drainpipe is provided with a third valve, and a heating pipe is connected to the drainpipe. The heating pipe is arranged on the bottom and the side wall of the pickling tank, and sodium hydroxide solution is housed in the heating pipe, but the stainless steel parts need to be When immersing in the tank, when pickling the tubular stainless steel parts, if the inner wall of the tubular stainless steel part does not need to be acidic, it is necessary to seal the nozzle of the stainless steel part, otherwise the pickling of the inner wall of the stainless steel part will cause acid The solution is wasted for no reason, and the operation of closed stainless steel parts will reduce the efficiency. In addition, when pickling longer and thicker tubular stainless steel parts, the size of the water tank is very high, resulting in the equipment occupying an area and pumping out the acid solution. trouble exists
