Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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.

[0025] Please refer to Figures 1-4 , the present utility model provides a double filter with a quick cleaning mechanism, including two cylinder bodies 1. The tops of the two cylinder bodies 1 are both fixedly communicated with liquid inlet pipes 4. One ends of the two liquid inlet pipes 4 are fixedly communicated with an upper three-way pipe 6 for inputting the liquid to be filtered. The top end of the cylinder body 1 is fixedly installed with a flange cover 2 through bolts. The middle part of the inner wall of the cylinder body 1 is fixedly connected with an annular seat 8. The inner wall of the annular seat 8 is engaged with a connecting ring 9. The bottom end of the connecting ring 9 is fixedly connected with a filter cartridge 18 for filtering particulate impurities in the liquid. Both sides of the inner wall of the annular seat 8 are provided with grooves 10. One side of the inner wall of the groove 10 is fixedly connected with an elastic sheet 11. One end of the elastic sheet 11 is fixedly connected with a clamping block 12. The top end of the inner wall of the groove 10 is provided with a through hole 15. The inner wall of the through hole 15 is penetrated by a pressing column 16 for disassembling and assembling the filter cartridge 18. The middle part of the flange cover 2 is rotatably connected with an inclined pipe 19 through a bearing. The bottom end of the inclined pipe 19 is fixedly connected with a flushing head 20 for cleaning the top area of the inner wall of the cylinder body 1.

[0026] During use, the liquid to be filtered is input from the upper three-way pipe 6, and is split into two filters through the liquid inlet pipe 4. The cartridge 18 filters out the particulate impurities therein. After opening the flange cover 2 of the filter, by pressing the two pressing columns 16 above the annular seat 8 simultaneously to make them move downward, the clamping blocks 12 on both sides can be squeezed and compressed back into the grooves 10, thus unlocking and removing the cartridge 18 below the connecting ring 9. After installing the cartridge 18, the clamping block 12 can be snapped into the side of the connecting ring 9 under the action of the elastic piece 11 to play a locking role. Therefore, the cartridge 18 in this duplex filter is convenient to disassemble and install, which is conducive to replacement and cleaning, and improves the maintenance efficiency.

[0027] The top end of the clamping block 12 is provided with an inclined surface groove 14. Both sides of the connecting ring 9 are provided with clamping grooves 13, and one end of the clamping block 12 is engaged with the inner wall of the clamping groove 13. Both sides of the top end of the connecting ring 9 are fixedly connected with handles 17 for easy operation.

[0028] During use, the clamping block 12 is snapped into the clamping groove 13 under the action of the elastic piece 11 to lock the positions of the connecting ring 9 and the cartridge 18. When the pressing column 16 moves downward, with the cooperation of the inclined surface groove 14, the clamping block 12 can be squeezed to disengage from the clamping groove 13, thus playing an unlocking role. The handle 17 is provided for easily lifting out the cartridge 18.

[0029] The bottom ends of the two cylinders 1 are both fixedly connected with liquid outlet pipes 5. One ends of the two liquid outlet pipes 5 are fixedly connected with a lower three-way pipe 26. Ball valves 7 are installed on the surfaces of the two liquid inlet pipes 4 and the two liquid outlet pipes 5 to control the opening and closing of the pipeline. Three legs 3 are evenly and fixedly connected to the bottom of the cylinder 1 to play a supporting role.

[0030] During use, the provided legs 3 are used to support the cylinder 1 for easy placement. The liquid to be filtered is input from the upper three-way pipe 6, split into two filters through the liquid inlet pipe 4, and after the particulate impurities are filtered out by the cartridge 18, they flow out from the two liquid outlet pipes 5 respectively and finally merge and discharge from the lower three-way pipe 26. When it is necessary to disassemble and clean the filter components in one of the filters, close the two ball valves 7 above and below on this side, and use the filter on the other side for operation to avoid the equipment from needing to stop.

[0031] One side of the top end of the flange cover 2 is fixedly installed with a reduction motor 22. The output end of the reduction motor 22 passes through the bottom end of the flange cover 2 and is fixedly connected with a driving gear 23. A driven gear 24 is fixedly sleeved on the top of the inclined pipe 19. The driving gear 23 is meshed with the driven gear 24 for transmission. The middle part of the top end of the flange cover 2 is fixedly connected with a bracket 25. The middle part of the bracket 25 is fixedly connected with a rotary joint 21, and the bottom end of the rotary joint 21 is rotatably connected with the top end of the inclined pipe 19 for connecting a water pipe.

[0032] During use, start the reduction motor 22 to drive the rotation of the driving gear 23, thereby driving the rotation of the inclined tube 19 sleeved with the driven gear 24. Then, introduce high-pressure water flow from the rotary joint 21, and let it spray out from the lower flushing head 20 along the inclined tube 19, which can wash off the particulate impurities adhering to the inner wall of the filter from the liquid, making the cleaning more convenient.

[0033] During specific use, for a double-connected filter with a quick cleaning mechanism of the present utility model, the liquid to be filtered is input from the upper three-way pipe 6, and is split into two filters through the liquid inlet pipe 4. After the particulate impurities are filtered out by the filter cartridges 18, they flow out from the two liquid outlet pipes 5 respectively, and finally merge and discharge from the lower three-way pipe 26. When it is necessary to disassemble and clean the filter components in one of the filters, close the two ball valves 7 above and below this side, and use the filter on the other side to work to avoid the equipment from stopping. After opening the flange cover 2 of the filter, press the two pressing columns 16 above the annular seat 8 simultaneously to make them move downward. With the cooperation of the inclined surface groove 14, the clamping blocks 12 on both sides can be squeezed and retracted into the grooves 10, and the locking can be released. Then, take out the filter cartridge 18 below the connecting ring 9 with the handle 17. After installing the filter cartridge 18, the clamping block 12 can be snapped into the card slot 13 on the side of the connecting ring 9 under the action of the elastic piece 11 to play a locking role. Thus, the filter cartridge 18 in this double-connected filter is convenient to disassemble and assemble, which is beneficial to replacement and cleaning, improves the maintenance efficiency. By starting the reduction motor 22 to drive the rotation of the driving gear 23, thereby driving the rotation of the inclined tube 19 sleeved with the driven gear 24. Then, introduce high-pressure water flow from the rotary joint 21, and let it spray out from the lower flushing head 20 along the inclined tube 19, which can wash off the particulate impurities adhering to the inner wall of the filter from the liquid, making the cleaning more convenient and reducing the maintenance time.
