The inner wall of the delivery pipe 13 is rotatably connected to a spiral delivery rod 15. A delivery motor 16 is fixed to the outer wall of one side of the delivery pipe 13. The output shaft of the delivery motor 16 is connected to the spiral delivery rod 15. A sewage outlet 14 is provided on the outer wall of the bottom surface of the end of the delivery pipe 13 away from the filter cartridge 8. A sewage outlet 14 is installed at the connection between the delivery pipe 13 and the filter cartridge 8. The spacing between the blades of the spiral delivery rod 15 gradually decreases from the sewage valve 12 to the sewage outlet 14. A filter screen 25 is provided at the bottom end of the delivery pipe 13.

[0029] The wastewater generated by cleaning is injected into the filter cartridge 8 from the drain pipe 3. The filter cartridge 8 filters the impurities contained in the wastewater. The filtered clean water returns to the water storage equipment from the drain pipe 3 for recycling. At the same time, the servo motor 5 drives the rotating shaft 9 to rotate, so that the scraper 11 scrapes off the impurities attached to the inner wall of the filter cartridge 8 to prevent the filter holes of the filter cartridge 8 from being blocked and affecting the filtration speed. The impurities filtered by the filter cartridge 8 are accumulated at the bottom of the filter cartridge 8 due to gravity. When a certain amount of impurities accumulates, the drain valve 12 is opened, the conveying motor 16 is started, and the spiral conveying rod 15 conveys the impurities in the filter cartridge 8 to the drain outlet 14 for discharge. During the conveying process, since the spacing between the blades of the spiral conveying rod 15 gradually decreases from the drain valve 12 to the drain outlet 14, the impurities are squeezed in the conveying pipe 13, and the water in the impurities is squeezed out and discharged through the filter mesh 25, reducing the water contained in the discharged impurities and facilitating subsequent treatment.

At the same time, during the filtering process, the servo motor 5 drives the scraper 11 to clean the inner wall of the filter cartridge 8 to avoid clogging of the filter holes and ensure the filtration rate.

[0031] By arranging the conveying pipe 13, the spiral conveying rod 15, the conveying motor 16 and the filter screen 25, since the spacing between the blades of the spiral conveying rod 15 gradually decreases from the sewage valve 12 to the sewage outlet 14, the impurities are squeezed in the conveying pipe 13, and the water in the impurities is squeezed out and discharged through the filter screen 25, thereby reducing the water content in the discharged impurities and facilitating subsequent processing.

[0032] Example 2

[0033] A PET bottle flakes washing water recycling device, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 2 、 Figure 4 As shown, the connecting rod 10 and the scraper 11 are connected by a connecting assembly, which includes a limiting groove 18 and a connecting block 17. The limiting groove 18 is opened on the outer wall of one side of the connecting rod 10, and the connecting block 17 is fixed to the outer wall of one side of the scraper 11. The connecting block 17 slides with the limiting groove 18. The outer walls on both sides of the connecting block 17 are provided with a cavity 22, and the inner wall of the cavity 22 is slidingly connected to the limiting block 21. The outer wall of the limiting block 21 is inclined. A limiting spring 20 is fixed on the outer wall of one side of the limiting block 21, and the other end of the limiting spring 20 is connected to the inner wall of the cavity 22. A limiting hole 19 is opened on the inner wall of the limiting groove 18, and the limiting hole 19 cooperates with the limiting block 21. A movable cavity 23 is opened on both sides of the connecting rod 10, and a push rod 24 slides with the inner wall of the movable cavity 23. A return spring 26 is fixed to the outer wall of one side of the push rod 24, and the other end of the return spring 26 is connected to the inner wall of the movable cavity 23.

[0034] When removing the scraper 11, push the push rod 24, and the push rod 24 squeezes the limit block 21, so that the limit block 21 shrinks into the cavity 22 and disengages from the limit hole 19. At this time, pull the connecting block 17 to one side, pull the connecting block 17 out of the limit groove 18, and remove the scraper 11. When installing, insert the connecting block 17 into the limit groove 18, and the limit block 21 is squeezed by the inner wall of the limit groove 18 and shrinks into the cavity 22. When the connecting block 17 is inserted a certain distance, the limit block 21 is aligned with the limit hole 19, and the limit block 21 is inserted into the limit hole 19 under the push of the limit spring 20, completing the installation of the scraper 11.

[0035] By setting up a connecting component, pushing the push rod 24, the push rod 24 squeezes the limit block 21, so that the limit block 21 shrinks into the cavity 22 and disengages from the limit hole 19. At this time, pulling the connecting block 17 to one side and pulling the connecting block 17 out of the limit groove 18 can remove the scraper 11, which facilitates the disassembly and replacement of the scraper 11 and improves work efficiency.

[0036] Working principle: the waste water generated by cleaning is injected into the filter cartridge 8 from the water inlet pipe 6, and the filter cartridge 8 filters the impurities contained in the waste water. The filtered clean water returns to the water storage equipment from the drain pipe 3 for recycling. At the same time, the servo motor 5 drives the rotating shaft 9 to rotate, so that the scraper 11 scrapes off the impurities attached to the inner wall of the filter cartridge 8 to avoid clogging of the filter holes of the filter cartridge 8 and affecting the filtration speed. The impurities filtered by the filter cartridge 8 are accumulated at the bottom of the filter cartridge 8 by gravity. When a certain amount of impurities accumulate, the drain valve 12 is opened, the conveying motor 16 is started, and the spiral conveying rod 15 conveys the impurities in the filter cartridge 8 to the drain outlet 14 for discharge. During the conveying process, the spacing between the blades of the spiral conveying rod 15 gradually decreases from the drain valve 12 to the drain outlet 14, and the impurities are discharged in the conveying pipe 13. Under the squeeze, the moisture in the impurities is squeezed out and discharged through the filter 25, reducing the moisture contained in the discharged impurities and facilitating subsequent processing. When the scraper 11 is worn and needs to be disassembled and replaced, push the push rod 24, and the push rod 24 squeezes the limit block 21, so that the limit block 21 shrinks into the inside of the cavity 22 and disengages from the limit hole 19. At this time, pull the connecting block 17 to one side, pull the connecting block 17 out of the limit groove 18, and remove the scraper 11. When installing, insert the connecting block 17 into the limit groove 18, and the limit block 21 is squeezed by the inner wall of the limit groove 18 to shrink into the inside of the cavity 22. When the connecting block 17 is inserted a certain distance, the limit block 21 is aligned with the limit hole 19, and the limit block 21 is inserted into the limit hole 19 under the push of the limit spring 20, completing the installation of the scraper 11.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
