[0002] Automatic backwashing wastewater filtration devices are equipment that use filter screens and filter cartridges to separate impurities in water, remove suspended solids and particulate matter, reduce turbidity, and purify water quality. Their main function is to protect other equipment in the system from impurities and ensure their normal operation.

[0003] Existing automatic backwashing wastewater filtration devices require the backwashing system to be activated during backwashing, allowing clean water and other liquids to flow through the filter in a counter-current manner to flush away impurities on the filter screen. However, during the backwashing process, the internal structure of the filter screen may have gaps and holes, which can easily trap dirt and grime. The water flow cannot fully reach these areas during backwashing, resulting in incomplete backwashing and affecting the subsequent filtration effect. Therefore, a new type of automatic backwashing wastewater filtration device is needed. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see Figure 1-6 This utility model provides a technical solution: an automatic backwashing wastewater filtration device, comprising: a fixed plate 1; a first fixed block 2 fixedly connected to the outer surface of the fixed plate 1; a second fixed block 3 fixedly connected to the top and bottom of the first fixed block 2; a cylindrical barrel 4 fixedly connected between the outer surfaces of the two second fixed blocks 3; a first water inlet pipe 5 fixedly connected to the bottom of the cylindrical barrel 4 near one side edge; a sliding groove 6 opened at one end of the first water inlet pipe 5; a sliding block 7 slidably connected to the inner wall of the sliding groove 6; a first water outlet pipe 8 fixedly connected to the outer surface of the sliding block 7; a fixed shaft 9 fixedly connected to the inner wall of the first water outlet pipe 8; and a plurality of evenly arranged inclined blade fans 10 fixedly connected to the outer surface of the fixed shaft 9; a filter screen 16 is provided on the inner wall of the cylindrical barrel 4, and the filter screen 16 is a cylindrical thin-walled structure.

[0026] like Figure 3-5 As shown, the inner wall of the filter screen 16 slides against the outer surface of the first water outlet pipe 8. By setting the filter screen 16, dirt in the water can be intercepted.

[0027] like Figure 1-3As shown, the outer surface of the cylinder 4 is fixedly connected to the second water outlet pipe 12 near the top, and the outer surface of the cylinder 4 is fixedly connected to the second water inlet pipe 13 near the bottom. By setting the second water outlet pipe 12, the water in the cylinder 4 can flow out from the second water outlet pipe 12.

[0028] like Figure 1-3 As shown, the bottom of the cylindrical barrel 4 is fixedly connected to the third water outlet pipe 14 near one side edge, and a collection box 15 is provided on the outer surface of the fixing plate 1. By providing the collection box 15, the water flowing out of the third water outlet pipe 14 can be collected.

[0029] like Figure 3-6 As shown, the outer surfaces of multiple inclined blade fans 10 are all in contact with the inner wall of the first water outlet pipe 8. Multiple evenly arranged round holes 11 are opened on the outer surface of the first water outlet pipe 8. Water can flow out from the round holes 11 by opening round holes 11 on the outer surface of the first water outlet pipe 8.

[0030] like Figure 1 As shown, the top of the fixing plate 1 is fixedly connected to the water tank 17, and the outer surface of the water tank 17 is provided with a water pump 18. The outer surface of the water tank 17 is fixedly connected to the third water inlet pipe 19 and extends to the inside. By providing the third water inlet pipe 19, water in the water tank 17 can flow into the third water inlet pipe 19.

[0031] like Figure 1 As shown, one end of the third water inlet pipe 19 is fixedly connected to the input end of the water pump 18 with screws, and the output end of the water pump 18 is fixedly connected to the fourth water outlet pipe 20 with screws. One end of the fourth water outlet pipe 20 is fixedly connected to the other end of the first water inlet pipe 5. Through the fixed connection between the fourth water outlet pipe 20 and the first water inlet pipe 5, water can flow from the fourth water outlet pipe 20 into the first water inlet pipe 5.

[0032] The operating method and working principle of this device: During normal operation, water containing impurities enters the cylindrical tank 4 through the second inlet pipe 13. The impurities are then intercepted by the filter screen 16 within the cylindrical tank 4, and clean water flows out through the second outlet pipe 12 to the next stage. However, when too many impurities adhere to the filter screen 16, it affects the filtration effect on subsequent water, necessitating cleaning. This requires starting the water pump 18, which generates suction to draw water from the water tank 17 into the third inlet pipe 19. The water then flows along... The water flows into the pump 18 through the inner wall of the third inlet pipe 19. The pump 18 generates pressure to force water into the fourth outlet pipe 20. The rinsing water flows from the fourth outlet pipe 20 into the first inlet pipe 5, and then along the first inlet pipe 5 into the first outlet pipe 8. In the first outlet pipe 8, the water continues to flow upward along the inner wall of the first outlet pipe 8. As the rinsing water continues to flow upward, the pressure of the rinsing water causes the multiple inclined blades 10 on the inner wall of the first outlet pipe 8 to rotate. The rotation of the multiple inclined blades 10 causes the fixed shaft 9 to rotate, and the rotation of the fixed shaft 9 causes the first outlet pipe to rotate. When pipe 8 rotates, the outer surface of slider 7 rotates along the inner wall of groove 6. Simultaneously, water flows out from multiple holes 11 on the first outlet pipe 8 to clean the filter screen 16. The rinsing water, carrying impurities, flows downwards into the third outlet pipe 14 and then out. Finally, the wastewater containing impurities flows into collection box 15, effectively preventing contamination of the fixing plate 1 and ensuring its cleanliness. The rinsing water remains clean until it flows out of the third outlet pipe 14. When the water pump 18 is turned off, the device delivers water through the water pump 18. Multiple inclined blade fans 10 are installed on the inner wall of the first water outlet pipe 8. The water flow drives the inclined blade fans 10 to rotate, thereby driving the first water outlet pipe 8 to rotate. When the first water outlet pipe 8 rotates, water will spray out from multiple round holes 11, thereby thoroughly cleaning the filter screen 16. This can effectively prevent dirt and grime from accumulating in the gaps and holes of the filter screen 16. The water flow drives the first water outlet pipe 8 to rotate, causing water to spray out from the round holes 11 when the first water outlet pipe 8 rotates, thereby thoroughly rinsing the filter screen 16 and ensuring the subsequent filtration effect of the filter screen 16.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
