Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a self-cleaning wastewater treatment device. Background Technology

[0002] If wastewater is discharged directly without effective treatment, it will cause serious damage to the ecological environment and threaten water resource security, soil quality and biodiversity. Therefore, efficient wastewater treatment equipment is crucial for environmental protection and sustainable development.

[0003] During operation, wastewater treatment devices are prone to clogging by impurities, suspended solids, and microorganisms in the wastewater. Existing solutions include designing a structure that allows for quick replacement of filter plates and adding high-pressure nozzles to prevent clogging. However, high-pressure nozzles can only rinse a single area, which fails to thoroughly remove stubborn dirt, resulting in reduced treatment efficiency, increased energy consumption, and frequent manual cleaning that is not only costly in terms of manpower, resources, and time but can also disrupt the normal operation of the device if cleaning is not done in a timely manner. Therefore, a self-cleaning wastewater treatment device is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a self-cleaning wastewater treatment device, which aims to improve the problem that the high-pressure nozzles in the prior art can only rinse a single location, thus failing to completely remove stubborn dirt.

A filter cylinder 3 is connected to the left side of the wastewater treatment tank 1, and a filter plate 4 is fixedly connected to the right side of the filter cylinder 3. Wastewater is discharged through the filter cylinder 3, and impurities in the wastewater are filtered by the filter plate 4 along the way. A fixing plate 5 is fixedly connected to the right side of the wastewater treatment tank 1, and a servo motor 6 is fixedly connected to the right side of the fixing plate 5. The output end of the servo motor 6 passes through the right side of the fixing plate 5 and is fixedly connected to a gear 7. A rotating connector 8 is rotatably connected to the right side of the wastewater treatment tank 1, and a gear ring 9 is fixedly connected to the outer wall of the rotating connector 8. The rotating connector 8 is installed on the right side of the wastewater treatment tank 1, and sufficient sealing is provided between them. By starting the servo motor 6, the gear 7 is driven to rotate. At this time, under the transmission effect of the gear ring 9, the left end of the rotating connector 8 is connected to a hollow rod 10, and a cleaning brush 11 is fixedly connected to the left end of the hollow rod 10, driving the cleaning brush on the left end of the hollow rod 10.

Multiple water outlet pipes 12 are connected to the left end of the outer wall of the hollow rod 10, and nozzles 13 are connected to the outer wall of each water outlet pipe 12. A water supply pipe 14 is connected to the left end of the rotating connector 8, and the other end of the water supply pipe 14 is connected to the top of the water supply tank 15. To ensure thorough cleaning of the filter plate 4 by the cleaning brush 11, water is injected into the hollow rod 10 through the water supply pipes 14 and then sprayed onto the surface of the filter plate 4 through the nozzles 13. This improves cleaning efficiency, and the cleaned impurities will settle at the bottom of the wastewater treatment tank 1. The bottom of the wastewater treatment tank 1 is connected to a discharge valve 21. By setting a specified time, the discharge valve 21 is activated to discharge the internal impurities to the outside, thus achieving self-cleaning.

[0032] Specifically, when wastewater is discharged through filter cartridge 3, it passes through filter plate 4, which effectively filters impurities in the wastewater. Servo motor 6 is supported by fixing plate 5 to ensure its stable operation. Rotary connector 8 is installed on the right side of wastewater treatment tank 1, and a proper seal is maintained between them. Starting servo motor 6 drives gear 7 to rotate.

A water supply pipe 14 is connected to the left end of the rotating connector 8, and the other end of the water supply pipe 14 is connected to the top of the water supply tank 15. In order to ensure that the cleaning brush 11 fully cleans the filter plate 4, the water supply tank 15 injects water into the hollow rod 10 through the water supply pipe 14, and rinses the surface of the filter plate 4 through the nozzles 13, thereby improving the cleaning efficiency. At the same time, the cleaned impurities will settle at the bottom of the wastewater treatment tank 1.

When the water level reaches the specified height, the water pump 202 is started to transport the water back to the water supply tank 15 to complete the circulation.

[0034] Specifically, the circulation pipe 201 is connected to the bottom of the water supply tank 15, allowing the filtered water to be reinjected into the water supply tank 15, thus facilitating continuous water use. The other end of the circulation pipe 201 is connected to the water pump 202, and the other end of the water pump 202 is connected to the connecting pipe 203. The left end of the connecting pipe 203 is connected to the water collection tank 204. All impurities and flushing wastewater flow into the water collection tank 204. To further improve water quality, a filter tank 206 is installed on the top of the water collection tank 204, which can effectively filter impurities in the water. In addition, a liquid level sensor 205 is installed on the left side of the outer wall of the water collection tank 204, which can monitor the water level in the water collection tank 204 in real time.

This circulation mechanism 2 design not only improves water utilization but also ensures the cleanliness and safety of the water quality through real-time monitoring and filtration.

[0037] Working principle: First, wastewater is discharged out through filter cylinder 3. During this process, impurities in the wastewater are filtered by filter plate 4. The servo motor 6 drives gear 7 to rotate. Under the transmission effect of gear ring 9, the rotating connecting piece 8 drives the cleaning brush 11 at the left end of hollow rod 10 to rotate, so that the cleaning brush 11 scrapes off the impurities on the surface of filter plate 4. At the same time, water supply tank 15 injects water into hollow rod 10 through water pipe 14 and sprays the surface of filter plate 4 through nozzle 13 to improve cleaning efficiency. Meanwhile, the cleaned impurities will settle at the bottom of wastewater treatment tank 1. By setting a specified time, the discharge valve 21 is activated to discharge the internal impurities to the outside, realizing self-cleaning.

[0038] Furthermore, the wastewater discharged during rinsing flows into the water collection tank 204. The filter tank 206 at the top of the water collection tank 204 filters the impurities in the wastewater and stores them in the filter tank 206. The filtered water flows into the water collection tank 204, and the water level in the water collection tank 204 is detected in real time by the liquid level sensor 205. When the water level reaches the specified height, the water pump 202 is started to transport the water back to the water supply tank 15, completing the recycling process.
