Description

Technical Field

[0001] The utility model relates to the technical field of filter cleaning equipment, in particular to a filter cleaning device. Background Art

[0002] Filters are widely used in the fields of metallurgy, chemical engineering, petroleum, papermaking, medicine, food, mining, electricity, and urban water supply. They are precision equipment that use a mesh to directly intercept impurities in water, remove suspended solids and particulate matter, reduce turbidity, purify water quality, and reduce system fouling, algae, and rust, thereby purifying water quality and protecting the normal operation of other system equipment. After a period of use, the filter's internal mesh is easily clogged with dirt and needs to be disassembled and cleaned. Traditional filter cleaning methods often rely on manual labor, such as wiping the filter surface with a rag to remove impurities. This method is not only inefficient but also has limited cleaning effects.

[0003] A search revealed Chinese patent application number 201922289329.5, which discloses a filter cleaning device comprising a support leg, a main body, a rubber sleeve, a bucket seat, and an ultrasonic generator. The main body has hinged seats at each of the four corners of its bottom end, and the support legs are hingedly connected to both sides of the main body's bottom through the hinged seats. A cover is secured to the top of the main body, and a groove is formed at the edge of the main body's top that mates with the cover. A rubber sleeve is secured to the bottom of the main body, and the bucket seat is secured to the bottom end of the rubber sleeve. The filter cleaning device comprises support legs and rubber sleeves, which are hinged to the main body so that they can be rotated upward and retracted when not in use. The design of the rubber sleeves allows the bucket seat to be directly pressed into the main body when not in use, allowing the entire device to be folded up, reducing floor space and facilitating storage.

[0004] However, the cleaning device of the above filter still has the following defects:

[0005] The cleaning device only cleans the filter screen plate through an ultrasonic generator, and the cleaning effect is not ideal, and the filter screen plate is not easy to disassemble. Therefore, we need a filter cleaning device to solve the above problems. Utility Model Content

[0024] See also Figure 1-6 The utility model provides a technical solution: a filter cleaning device, comprising a filter body 1, a driving motor 5 is installed at the top center of the filter body 1, the output shaft of the driving motor 5 is fixedly connected to a rotating rod 501, and stirring blades 502 are installed on the outer walls of the rotating rod 501, one end of the rotating rod 501 passes through the interior of the filter body 1 and is installed with a plurality of cross bars 504, and a mounting bracket 8 is installed on the inner wall of the filter body 1, and the mounting bracket 8 is U-shaped. A limiting groove 801 is provided inside the mounting bracket 8, and a fine filter plate 7 is installed in the limiting groove 801. A detachable mounting rod 2 is provided on one side of the fine filter plate 7, and a plurality of brushes 505 are installed at the bottom end of the cross bar 504. The plurality of brushes 505 are installed above the surface of the fine filter plate 7, and an elastic component for the brush 505 to contact the fine filter plate 7 is provided inside the bottom end of the rotating rod 501. One side of the bottom end of the filter body 1 is connected with a water outlet pipe 6;

[0025] During use, the driving motor 5 drives the rotating rod 501 and the stirring blades 502 and the brush 505 thereon to rotate. The brush 505 can directly act on the surface of the fine filter plate 7, effectively removing impurities, particulate matter, etc. attached to the fine filter plate 7, avoiding the tedious and time-consuming manual cleaning. When the fine filter plate 7 needs to be cleaned or replaced, it is only necessary to disassemble the mounting rod 2 and then remove it from the mounting bracket 8. There is no need to disassemble the entire filter body 1, saving maintenance time and cost. Through the design of the mounting bracket 8 and the limit groove 801, the fine filter plate 7 is effectively fixed and supported during the installation process, avoiding loosening or displacement caused by vibration or water impact, thereby enhancing the stability and reliability of the entire filtration system.

[0026] A liquid inlet 3 is provided on one side of the top of the filter body 1, and a detachable coarse filter plate 302 is installed inside the liquid inlet 3. The side walls of the coarse filter plate 302 are engaged with the inner wall of the liquid inlet 3, and handles 301 are installed on both sides of the top of the coarse filter plate 302. Since the coarse filter plate 302 is responsible for intercepting large particles of impurities, its wear rate is faster than that of the fine filter plate 7. However, due to its detachable design, the user can regularly replace the new coarse filter plate 302, thereby avoiding performance degradation or damage due to long-term use.

[0027] The elastic component includes a limit rod 503, a fixing block 506 and a return spring 507. A sliding groove 508 is provided inside the bottom end of the rotating rod 501, and the fixing block 506 is fixedly installed in the inner top end of the sliding groove 508. The bottom end of the fixing block 506 is fixedly connected to the top end of the return spring 507, the top of the limit rod 503 is fixedly connected to the bottom end of the return spring 507, the outer wall of the limit rod 503 is slidably connected to the inner wall of the sliding groove 508, and the bottom end of the limit rod 503 is fixedly connected to one end of multiple cross bars 504. Through the elastic action of the return spring 507, the limit rod 503 can slide up and down in the sliding groove 508, thereby realizing adaptive adjustment of the contact force between multiple cross bars 504 and the brush 505 and the fine filter plate 7, ensuring that the brush 505 can maintain appropriate pressure contact with the fine filter plate 7 in different working conditions, neither damaging the fine filter plate 7 due to excessive pressure nor affecting the cleaning effect due to insufficient pressure.

[0028] A through opening is provided on one side of the filter body 1, and the side wall of the mounting rod 2 is embedded in the through opening. A bolt 201 is installed on one side of the mounting rod 2, and a threaded hole 202 is provided on one side of the through opening. One end of the bolt 201 is threaded through the mounting rod 2 and is threadedly connected to the threaded hole 202. The design of the bolt 201 connection makes the disassembly and installation of the fine filter plate 7 simple and quick. When the fine filter plate 7 needs to be cleaned or replaced, the user only needs to loosen the bolt 201 to easily remove the mounting rod 2 and the fine filter plate 7 from the filter body 1, and then re-tighten the bolt 201 after completing the maintenance.

[0029] A clean water tank 4 is installed on the back of the filter body 1, and a connecting pipe 401 is connected to the top of the clean water tank 4. One end of the connecting pipe 401 passes through the top of the filter body 1 and extends to the inside of the top of the filter body 1. A nozzle 402 is installed at one end of the connecting pipe 401.

[0030] An inclined plate 9 is installed at the bottom end of the inner cavity of the filter body 1, and a plurality of drainage grooves 901 are equidistantly provided on the surface of the inclined plate 9. Due to the guiding effect of the inclined plate 9 and the drainage grooves 901, the residues generated during the filtration process are not easily accumulated at the bottom of the inner cavity of the filter body 1. These residues are more easily washed by the water flow to the drain outlet for discharge, thereby reducing the risk of pollution and blockage inside the filter body 1.

[0031] An ultrasonic generator 10 is installed on the inner wall of the filter body 1, and the ultrasonic generator 10 is installed on one side of the bottom end of the fine filter plate 7. A valve 601 is installed on the surface of one end of the water outlet pipe 6. After long-term use, the fine filter plate 7 is easily clogged due to accumulation of impurities, affecting the filtering effect. The vibration of the ultrasonic generator 10 can reduce the adhesion and accumulation of impurities, thereby delaying the occurrence of clogging and extending the service life of the fine filter plate 7.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
