Technical Field

[0001] The utility model relates to the technical field of chemical filters, in particular to a chemical filter which is convenient for cleaning residues. Background Art

[0002] Chemical filter is a filtering device used in the chemical production process. Its main function is to remove impurities, particulate matter, suspended solids, etc. in liquid or gas to ensure the quality of chemical products and the safety of the production process. Chemical filter is usually composed of filter body, filter element, filter screen, sealing element, inlet and outlet pipes, etc. Its working principle is to intercept impurities in the mixture on the surface of the filter element through the pressure difference of liquid or gas, while pure liquid or gas enters the outlet pipe through the filter element. The selection of chemical filter should be based on the specific conditions and requirements of the chemical production process, comprehensively considering the properties of the filter medium, flow, pressure, temperature, impurity content, filtration accuracy and other factors, and select the appropriate filter type and specifications.

Most filtering devices also need to clean the residues in the filter after filtering the residual liquid. It is not possible to directly process the residues and the residual liquid separately during the filtering process, which is not convenient enough. Utility Model Content

[0025] The two ends of the cross column 21 are fixedly connected to the inner wall of the body 1, and the inner wall of the body 1 is fixedly connected with a baffle 22. The surface of the body 1 is penetrated and rotatably connected with a rotating shaft 23.

The bevel gear 26 and the bevel gear 1 25 meshes with each other, the surface of the horizontal column 21 penetrates and is slidably connected with a lifting plate 29, and the two ends of the lifting plate 29 are fixedly connected with a filter screen 28. When in use, the chemical residue and residual liquid are poured into the hopper 7, and the chemical residue will be blocked by the filter screen 28, while the residual liquid will enter the collection box 5 through the filter screen 28. The filter screen 28 is slidably connected to the inner wall of the body 1, and the bottom surface of the lifting plate 29 is fixedly connected with a spring 1 210, and the end of the spring 1 210 away from the lifting plate 29 is fixedly connected to the inner side of the horizontal column 21. The rotating rod 27 is divided into three sections, and a reciprocating screw 212 is fixedly connected between each two sections of the rotating rod 27. When the motor 4 is started, the output shaft of the motor 4 will drive the rotating shaft 23 to rotate, and the rotating shaft 23 will drive the bevel gear 2 26 to rotate through the bevel gear 1 25, thereby rotating the rotating rod 27 and the reciprocating screw 212, and the reciprocating screw 212 penetrates and is threadedly connected with a screw sleeve 213. A scraper 214 is fixedly connected to the left side of the screw sleeve 213. When the reciprocating screw rod 212 rotates, it will drive the threaded screw sleeve 213 to reciprocate along the reciprocating screw rod 212, and further make the screw sleeve 213 drive the scraper 214 to scrape the filter screen 28. The right side of the screw sleeve 213 is fixedly connected to a connecting block 215.

When too much residue is accumulated on the filter screen 28, the scraper 214 will scrape the residue to the side close to the flip cover 6 when scraping the filter screen 28, and with the reciprocating movement of the sleeve 213, it will drive the connecting block 215 to move together, and each time the connecting block 215 moves to the side close to the flip cover 6 The pawl 216 arranged on the surface of the connecting block 215 will push the ratchet 218 to rotate a certain distance, and the ratchet 218 will drive the rotating column 217 to rotate, so that the half-toothed gear 219 will rotate a certain distance. When the screw sleeve 213 reciprocates a certain number of times, the rotating column 217 will drive the half-toothed gear 219 to engage with the rack 222, thereby forcing the rack 222 to be pushed by the half-toothed gear 219 to lift the flip cover 6, and the scraper 214 will scrape the accumulated residue from the edge of the filter screen 28 to another compartment of the collecting box 5, and the half-toothed gear 219 will no longer engage with the rack 222 after rotating a certain distance, and the spring 221 will pull the rack 222 back to its original position, and the reciprocating screw rod 212 will continue to rotate, so that the rack 222 will intermittently lift the flip cover 6, so that the residue will be discharged only after a certain amount of residue is accumulated each time. At the same time, the collecting box 5 with a compartment can handle the residue and the residual liquid separately, making the residue cleaning more convenient.

[0027] When the output shaft of the motor 4 drives the rotating shaft 23 to rotate, the rotating shaft 23 also drives the cam 24 to rotate. After the cam 24 rotates a certain distance, it will exert pressure on the lifting plate 29, forcing the lifting plate 29 to move downward. While compressing the spring 1 210, the lifting plate 29 will also drive the filter 28 downward. When the cam 24 rotates a certain distance and no longer conflicts with the lifting plate 29, the spring 1 210 will lift the lifting plate 29 to make the filter 28 shake, thereby improving the filtering effect of the filter 28 and avoiding blockage.
