Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic zinc, in particular to a filter press device for electrolytic zinc. Background Art

[0002] Electrolytic zinc is a chemical reaction that extracts pure zinc through electrolysis. The extraction-electrolysis method is used to further extract metallic zinc. The raw materials of the tailings are smelted to extract metallic zinc. The commonly used organic solvents tributyl phosphate and 2-[2-ethylhexyl] phosphoric acid are used as extractants to extract metallic zinc.

[0003] After the chemical reaction is completed, solid slag needs to be removed by filter pressing to obtain the solution required for electrolysis. Therefore, filter pressing is a very important unit step in the electrolytic zinc process.

[0004] After searching, it is found in a patent publication number CN216418466U that a high-efficiency filter press for electrolytic zinc production is "the utility model is provided with a reciprocating bidirectional compression liquid supply structure to realize continuous filter pressing, eliminating the idle stroke gap of the reciprocating filter press equipment, greatly improving the filter pressing efficiency, and being safe and reliable; it can conveniently clean the solid slag attached to the filter screen, avoid clogging of the filter screen, and operate stably."

[0005] However, the above scheme still has certain shortcomings in actual use. In this scheme, a vibrator is used to shake off the slag attached to the filter to avoid clogging of the filter. However, this cleaning method cannot effectively clean the filter, which greatly reduces the filtering effect of the filter. Utility Model Content

[0028] By setting up the driving structure 2, the gear motor 202 inside the driving box 201 drives the piston plate 207 to reciprocately squeeze the water inside the filter press box 101 by prompting the bending rod 206 on the front side of the rack 203, and then cooperates with the filter screen 103 to filter the water, thereby effectively improving the filtration effect.

[0029] The cleaning structure 3 includes a cleaning box 301, an inner wall of the cleaning box 301 is fixedly installed with a mounting frame 302, the inner side of the mounting frame 302 is rotatably connected with a screw rod 303 through a built-in motor, the surface of the screw rod 303 is threadedly connected with a threaded block 304, the side end of the threaded block 304 is fixedly connected with a cleaning soft brush 305 through a vertical rod, the cleaning soft brush 305 is a silicone brush, the bristles of the cleaning soft brush 305 overlap with the front side of the filter screen 103, and the cleaning soft brush 305 is located inside the filter press box 101.

[0030] By setting up the cleaning structure 3, the screw 303 inside the cleaning box 301 is used to drive the cleaning soft brush 305 to perform reciprocating lifting and lowering motion through the threaded block 304, so that the cleaning soft brush 305 can continuously clean the surface of the filter screen 103 and the scraped impurities will sink and enter the discharge box 106 through the one-way valve 105, and the cleaned filter screen 103 can be taken out from the filter press box 101 and replaced in time, so that the filter screen 103 is effectively cleaned, thereby improving the filtering effect of the filter screen 103.
