Description

Technical Field

[0001] This utility model relates to the field of filter cleaning technology, and in particular to a filter internal cleaning device. Background Technology

[0002] A filter is a device used to remove solid impurities from liquids or gases. It forces the fluid to be filtered through a filter medium under the action of a certain driving force, such as gravity, centrifugal force, pressure on the fluid above the filter, or vacuum below the filter. Solid impurities in the fluid are trapped by the filter medium, while the fluid passes through the filter medium, thereby achieving solid-liquid or solid-gas separation. An internal cleaning device for a filter is a component used to remove impurities inside the filter in order to restore the filter's filtration performance.

[0003] A search of Chinese patent publication number "CN222092749U" reveals "an internal cleaning device for a filter". This device uses a cleaning brush assembly and a cleaning drive assembly to work together. During the upward and downward displacement of the cleaning brush assembly, the cleaning brush performs self-cleaning on the filter screen, assisting the filter in filtration. The drain outlet sucks up and discharges sewage and dirt. The upward movement of the cleaning brush assembly can also assist the sewage to rise, improving the sewage discharge efficiency. During the downward movement, it can fully squeeze the dirt on the water surface, improving the filter screen filtration effect. Moreover, the small size of the cleaning brush saves materials while ensuring high cleaning efficiency.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. When the device is in use, its cleaning device and filter are integrated. Due to the integrated design, the internal structure is relatively complex. When maintenance personnel perform maintenance, they may need to disassemble the entire device. The operating space is limited, the maintenance is difficult and time-consuming, which will affect the normal operation of the equipment and lacks convenience. Utility Model Content

[0026] Example

[0027] like Figure 1 - Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem of insufficient convenience of existing devices. The overall idea is as follows:

[0028] In view of the problems existing in the prior art, the present invention provides a filter internal cleaning device, including a cylindrical filter body 11;

[0029] A cleaning structure is threadedly installed at the upper end of the cartridge filter body 11;

[0030] The cleaning structure includes a ring body 12, a rotating disk 13 is rotatably mounted inside the ring body 12, a small motor 14 is fixedly mounted on the circumferential surface of the ring body 12, the small motor 14 is located above the cartridge filter body 11, a gear 15 is fixedly mounted on the output shaft of the small motor 14, a gear ring 16 is fixedly mounted on the upper end of the rotating disk 13, the gear 15 and the gear ring 16 are meshed together, and a high-pressure nozzle 17 is fixedly mounted on the lower end of the rotating disk 13. The output shaft of the small motor 14 can drive the gear 15 and the gear ring 16 to mesh together, so that the rotating disk 13 drives the high-pressure nozzle 17 to rotate inside the cartridge filter body 11.

[0031] By setting up a cleaning structure, the operator only needs to install the ring 12 on top of the cartridge filter body 11 and turn on the small motor 14. The output shaft of the small motor 14 drives the gear 15 to mesh with the gear ring 16, causing the rotating disk 13 to drive the high-pressure nozzle 17 to rotate inside the cartridge filter body 11. This completes a cleaning structure that can be installed at any time, improving convenience.

[0032] A stop block 18 is fixedly installed on the side wall of the high-pressure nozzle 17, and the stop block 18 is slidably installed inside the cartridge filter body 11.

[0033] By setting a stop block 18 on the side wall of the high-pressure nozzle 17 and sliding the other side wall of the stop block 18 inside the cartridge filter body 11, support can be provided below the high-pressure nozzle 17 to avoid the problem of the high-pressure nozzle 17 shaking when high-pressure liquid is sprayed.

[0034] The high-pressure nozzle 17 is provided with a rigid pipe 19 at its upper end. The center of the other end of the rigid pipe 19 is parallel to the center of the rotating disk 13. The rigid pipe 19 is provided with a rotating joint 21 at its upper end. The ring body 12 is provided with a protective cover 22 at its upper end. The gear 15 and the rotating disk 13 are both located inside the protective cover 22. The rigid pipe 19 and the protective cover 22 are rotatably installed.

[0035] By setting a rigid pipe 19 and setting the center of the other end of the rigid pipe 19 to be parallel to the center of the rotating disk 13, and setting a rotating joint 21 above the rigid pipe 19, the high-pressure nozzle 17 can complete the normal delivery of liquid while rotating.

[0036] The cylindrical filter body 11 has a lower flange 23 on its circumferential surface, and an upper flange 24 at the upper end of the lower flange 23. The cylindrical filter body 11 has a cylindrical filter element 25 inside, and the high-pressure nozzle 17 is located on the outside of the cylindrical filter element 25.

[0037] The cartridge filter body 11 can be disassembled by setting a lower flange 23 on the cartridge filter body 11 and an upper flange 24 on the lower flange 23.

[0038] Working principle:

[0039] First, when using the equipment, the operator can first remove the upper flange 24 from the lower flange 23. Then, the operator can install the ring 12 on the cartridge filter body 11 with screws. At this time, the high-pressure nozzle 17 will be located inside the cartridge filter body 11, and the abutment 18 will be in contact with the inner wall of the cartridge filter body 11. Then, the operator can connect the water supply unit of the cleaning fluid to the rotary joint 21.

[0040] The second step involves the operator turning on the small motor 14, causing its output shaft to drive the gear 15 to rotate and mesh with the gear ring 16. This generates a radial force in the gear ring 16, causing the rotating disk 13 to rotate inside the ring body 12. Consequently, the high-pressure nozzle 17 drives the abutment block 18 to rotate inside the cartridge filter body 11, allowing the cleaning fluid sprayed from the high-pressure nozzle 17 to clean the circumferential surface of the cartridge filter element 25, thus completing the process. Simultaneously, the cleaned liquid will leak out from the drain port at the bottom of the cartridge filter body 11.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
