When the device is used, S1, firstly, the infusion tube 2 in the center is connected with a device for outputting water, then the infusion tubes 2 on two sides are connected with a device for outputting acid solution, when pickling is carried out, the rotating shaft 5 is rotated to enable the two ends with long diameter of the magnetic plate 6 to be distributed at the left and the right, the side frames 3 are expanded under the magnetic force action of the magnetic plate 6, the two infusion grooves 4 respectively correspond to the infusion tubes 2 on the left and the right, the connecting tube A7 pushes the two lantern rings 9 to be mutually combined along with the expansion of the side frames 3 to clamp the stainless steel piece, then the acid solution is output into the infusion grooves 4, the acid solution is input into the liquid outlet groove 10 through the infusion groove 4, the connecting tube A7 and the connecting tube B8 and then is coated on the stainless steel piece through the liquid outlet groove 10 and the filter sieve 11, the acid solution passes through the rotating ring 32 in the process of flowing in the liquid outlet groove 10, the fan plate 34 drives the rotating ring 32 to rotate under the action of the acid solution, swivel 32 drives lantern ring 9 through frictional force and slides on stainless steel outer wall, thereby let lantern ring 9 at pickling in-process automatic movement, be the setting of diffusion tubular shape through liquid outlet tank 10 in addition, increase the rivers pressure when acid solution passes through swivel 32, after the pickling, rotate pivot 5 and let about the both ends distribution that magnetic sheet 6 diameter is short, side frame 3 closes under magnetic action of magnetic sheet 6, two liquid delivery groove 4 all correspond to the transfer line 2 that is located the center, then export water is exported through liquid outlet tank 10 in the liquid delivery groove 4, after two side frames 3 are close to each other, two lantern rings 9 separate under the pulling of connecting pipe A7 and connecting pipe 8, thereby spray out from stainless steel top in the in-process of rivers output, utilize the difference in height to increase the effect and the intensity that rivers hit stainless steel, thereby increase the cleaning performance.

S2, the magnetic force of the magnetic plate 6 is conducted to the magnetic conduction plate 15 through the toothed plate 20, the plug rod 19, the piston A18 and the inserting cylinder 17, the magnetic conduction plate 15 attracts the stainless steel piece, the stainless steel piece is attached to the top plate 14, the stability of the stainless steel piece on the inserting shaft 12 is improved, when the stainless steel piece is attached to the top plate 14, an extrusion effect can be generated on the elastic air cushion 16, air in the elastic air cushion 16 is injected into the inserting cylinder 17 and pushes the piston A18 to slide, the piston A18 pulls the toothed plate 20 to slide through the plug rod 19 when sliding, the toothed plate 20 drives the rotating shaft 5 to rotate through the tooth grooves when sliding, so that the two side frames 3 are automatically driven to be expanded, the lantern ring 9 is used for clamping the stainless steel piece, and the pickling operation is convenient to be quickly started.

S3, in the process that the stainless steel piece is inserted into the plug shaft 12 and attached to the top plate 14, the stainless steel piece pushes the pressure plate 28, the pressure plate 28 is pressed downwards under force and pulls the piston B24 to descend, negative pressure is generated in the piston B24 and air in the elastic expansion pad 22 is sucked in, the elastic expansion pad 22 contracts and pulls the lantern ring 9 to be close to the top plate 14, the lantern ring 9 corresponds to the rear end of the stainless steel piece, the pickling range is ensured, the elastic expansion pad 22 on the rear side can expand in the sliding process of the side frame 3, air in the cylinder 23 is sucked in, the piston B24 slides in the cylinder 23 under the action of the negative pressure and pulls the spring A25 to expand, when the lantern ring 9 is separated from clamping of the stainless steel piece, the spring A25 rebounds to allow the piston B24 to suck air, and the lantern ring 9 is pulled to reset.

S4, when the bump 35 contacts the push rod 36 in the rotation process of the rotating ring 32, the push rod 36 is forced to push the scraping ring 31 to rotate, when the scraping ring 31 rotates, the brush is used for scraping and cleaning the stainless steel part, then when the bump 35 is separated from the push rod 36 along with the rotation, the cleaning ring 30 drives the push rod 36 to reset under the action of air flow, and the brush is used for scraping and cleaning the stainless steel part once.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
