Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model:

[0025] A filter cleaning device includes a filter body 5. A cover plate 1 is arranged on the upper part of the filter body 5. A motor 2 is fixedly connected to the upper part of the cover plate 1. The output end of the motor 2 is fixedly connected to a limiting rod 27. A limiting block 12 is fixedly connected to the lower part of the limiting rod 27. A limiting groove 26 is formed inside the limiting block 12. A ring-shaped frame 17 is arranged inside the filter body 5. A filter screen 14 is clamped inside the ring-shaped frame 17. A connecting shaft 15 is fixedly connected to the outside of the ring-shaped frame 17. The upper connecting shaft 15 is clamped inside the limiting groove 26. The lower connecting shaft 15 and the limiting rod 27 are rotatably connected inside the filter body 5. A brush plate 13 is fixedly connected to the right side inside the filter body 5. A water collecting pipe 18 is fixedly connected to the left side inside the filter body 5. A plurality of high-pressure nozzles 19 are fixedly communicated with the right part of the water collecting pipe 18. A connecting pipe 9 is fixedly communicated with the left side of the water collecting pipe 18. A water pump 8 is fixedly communicated with the left part of the connecting pipe 9. A controller 4 is fixedly connected to the front part of the filter body 5. Installation components are arranged on both sides of the lower part of the cover plate 1;

[0026] The motor 2 is started by the controller 4. The output end of the motor 2 drives the connecting shaft 15 to rotate. The connecting shaft 15 is clamped with the limiting groove 26 inside the limiting block 12, so as to drive the filter screen 14 inside the annular frame 17 to rotate. At the same time, an external water source is injected into the connecting pipe 9 through the external water pump 8, enters the water collecting pipe 18 from the connecting pipe 9, and sprays and washes the filter screen 14 through the high-pressure nozzle 19. When the filter screen 14 rotates, it will pass by the brush plate 13 on the right side inside the filter body 5, which can clean the impurities on the surface of the filter screen 14, and can complete the cleaning work without disassembling the filter screen 14, reducing the number of times of disassembling and cleaning the filter.

[0027] Refer to Figure 1 and Figure 3 , the installation component includes a fixing plate 11. The fixing plate 11 is fixedly connected to both sides of the upper part of the filter body 5. Installation blocks 3 are fixedly connected to both sides of the lower part of the cover plate 1. A sliding plate 28 is arranged inside the installation block 3. A slider 20 is fixedly connected to the outside of the sliding plate 28. A sliding groove 21 is opened inside the installation block 3. A sliding rod 22 is fixedly connected to the right part of the sliding plate 28. A pull plate 23 is fixedly connected to the right part of the sliding rod 22. A spring 24 is arranged outside the sliding rod 22. A fixing block 29 is fixedly connected to the left part of the sliding plate 28. A clamping block 25 is arranged on the left part of the installation block 3;

[0028] First, pull the pull plate 23. The pull plate 23 drives the fixing block 29 on the sliding plate 28 to move through the sliding rod 22. At the same time, the slider 20 slides inside the sliding groove 21, so that the fixing block 29 is separated from the clamping block 25, thereby opening the cover plate 1. Then place the cover plate 1 on the top of the installation block 3, and then release the pull plate 23, so that the spring 24 drives the fixing block 29 to rebound, so that the clamping block 25 at the bottom of the cover plate 1 squeezes the fixing block 29, and the fixing block 29 is clamped with the clamping block 25, thereby fixing the cover plate 1 on the top of the filter body 5.

[0029] Refer to Figure 1 , Figure 2 and Figure 3 , the fixing block 29 is slidably connected inside the clamping block 25. A water inlet pipe 10 is fixedly communicated with the left side of the upper part of the filter body 5. A water outlet pipe 6 is fixedly communicated with the right side of the lower part of the filter body 5. The slider 20 is slidably connected inside the sliding groove 21. Support legs 7 are fixedly connected to the four corners of the bottom of the filter body 5. A sewage pipe 16 is fixedly communicated inside the filter body 5;

[0030] By sliding the fixed block 29 inside the clamping block 25, the fixed block 29 can be separated from the clamping block 25 to open the cover plate 1. By providing the water inlet pipe 10 and the water outlet pipe 6, the filtered water can be introduced and discharged. By sliding the slider 20 inside the chute 21, the fixed block 29 on the sliding plate 28 can be stably moved. By providing the support legs 7, the filter body 5 is supported. By providing the sewage discharge pipe 16, the sewage after cleaning is discharged.

[0031] Working principle: When using this device, the motor 2 is started through the controller 4. The motor 2 drives the filter net 14 inside the annular frame 17 to rotate through the connecting shaft 15 and the limit block 12. At the same time, an external water source is injected into the connecting pipe 9 through an external water pump 8 and enters the water collecting pipe 18 from the connecting pipe 9. The filter net 14 is sprayed and washed through the high-pressure nozzle 19. At the same time, when the filter net 14 rotates, the brush plate 13 on the right side inside the filter body 5 can clean the impurities on the surface of the filter net 14. The sewage after cleaning is discharged through the sewage discharge pipe 16. When the filter net 14 needs to be cleaned or replaced, first pull the pull plate 23. The pull plate 23 drives the fixed block 29 on the sliding plate 28 to move through the slide bar 22. At the same time, the slider 20 slides inside the chute 21 to separate the fixed block 29 from the clamping block 25, thereby opening the cover plate 1. At the same time, the connecting shaft 15 is slid out of the limit groove 26 of the lower limit block 12 of the limit rod 27, and the filter net 14 is disassembled from the annular frame 17 for replacement. After replacing the filter net 14, the filter net 14 is placed on the annular frame 17 and the filter net 14 is limited and fixed. Then the cover plate 1 is placed on the top of the mounting block 3, and the clamping block 25 at the bottom of the cover plate 1 squeezes the fixed block 29 to make the fixed block 29 engage with the clamping block 25, thereby fixing the cover plate 1 on the top of the filter body 5.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
