Description
Technical Field
[0001] This utility model relates to the technical field of sewage treatment devices, specifically a sewage treatment device that facilitates cleaning of filter screens. Background Technology
[0002] Wastewater treatment equipment can effectively treat domestic sewage and industrial wastewater in urban areas, preventing sewage and pollutants from flowing directly into water bodies. It is of great significance for improving the ecological environment, enhancing the city's image, and promoting economic development. Wastewater treatment requires the use of filter plates to filter particulate matter. Sewage enters the sludge removal tank through the inlet pipe or inlet funnel. After being filtered by the filter screen, the clean sewage is discharged through the outlet pipe. During operation, dirt and impurities will gradually accumulate on the filter screen, so the filter screen needs to be cleaned regularly.
[0003] Nowadays, most filter screens in sewage treatment devices are installed inside the device. This means that when cleaning is needed, the machine usually needs to be stopped and the device opened for internal work. While this arrangement saves space, it also increases the difficulty and complexity of cleaning. Furthermore, cleaning the filter screens may require disassembling the filter screens inside the device, which increases the complexity and time cost of the operation, making the cleaning of filter screens in sewage treatment devices quite inconvenient.

The cleaning mechanism includes a moving mechanism for moving the filter plate 5 to the cleaning chamber 15 and a flushing mechanism for rinsing the filter plate 5 inside the cleaning chamber 15. The brush flushing mechanism and moving mechanism include a frame 7 and a housing 10. The flushing mechanism includes a housing 17 and a water outlet 21. The treatment tank 1 is the main body of the entire device, and it is equipped with a filter chamber 2 and a cleaning chamber 15. The filter chamber 2 is located inside the treatment tank 1 and is used to accommodate the filter plate 5 and treat sewage. The inlet 3 and outlet 4 are respectively set on the treatment tank 1 and cooperate with the filter chamber 2 to realize the inflow and outflow of sewage. The filter plate 5 is installed inside the filter chamber 2 to filter the sewage and remove impurities. Through the installation of the frame 7 and the housing 10, when it is necessary to clean the filter plate 5, the motor 1 inside the housing 10 is activated. 2. Upon startup, motor 12 drives frame 7 and its internal filter plate 5 to move along the limiting slide groove 6 within treatment chamber 1, moving from filter chamber 2 to cleaning chamber 15, preparing for subsequent rinsing and cleaning. As the electric telescopic rod 26 inside the waterproof protective shell 25 starts, its output end drives the filter plate 5 downwards, separating it from frame 7 and tilting it to better flush away dirt and impurities. Simultaneously, water pump 19 inside shell 17 and motor 24 outside treatment chamber 1 start, with pump 19 providing cleaning water and motor 24 driving the outlet 21... The cleaning chamber 15 moves at a constant speed, causing the nozzles 28 on the outlet 21 to spray cleaning water. The impact force of the water flow washes away the dirt and impurities attached to the filter plate 5. After cleaning, the electric telescopic rod 26 and motor 12 are restarted. The electric telescopic rod 26 lifts the filter plate 5 back to its original position and reassembles it with the frame 7. The motor 12 drives the frame 7 and the filter plate 5 back to the filter chamber 2 along the limiting slide 6, ready for the next sewage filtration operation. The entire cleaning process of the filter plate 5 does not require manual intervention, improving work efficiency and safety, and making the cleaning and maintenance of the filter plate 5 simpler and faster.
[0022] Please see Figure 2 and Figure 3 The processing box 1 has a limiting groove 6 inside, and a frame 7 is movably mounted inside the limiting groove 6. The filter plate 5 is movably fitted inside the frame 7. Two sets of lead screws 8 are rotatably mounted inside the limiting groove 6, and lead screw nuts 9 are meshed on the lead screws 8. The outside of the lead screw nuts 9 is fixedly connected to the outside of the frame 7. A housing 10 is fixedly mounted on one side of the processing box 1. A gear 11 is fixedly mounted on one end of the lead screws 8 and is located inside the housing 10. A motor 12 is fixedly mounted inside the housing 10. A gear 13 is fixedly mounted on the output end of the motor 12, and the gear 13 is connected to the gear 11 by a chain 14. The processing box 1 is the main structure used to contain and process various substances. The limiting groove 6 inside the processing box 1 is for guiding and... The frame 7 and the filter plate 5 inside it are restricted in their direction and path of movement, allowing the frame 7 and the filter plate 5 inside it to move within the filter chamber 2 and the cleaning chamber 15. The frame 7 is a movable structure, with the filter plate 5 movably fitted inside it, so that the filter plate 5 can be moved or adjusted as a whole through the frame 7. When the motor 12 starts, the gear 13 at its output end begins to rotate. Through the transmission of the chain 14, the gear 11 also rotates. The rotation of the gear 11 drives the lead screw 8 to rotate. The rotation of the lead screw 8 causes the lead screw nut 9, which meshes with it, to move along the axial direction of the lead screw 8. Since the lead screw nut 9 is fixedly connected to the frame 7, the frame 7 and the filter plate 5 inside it will also move, moving from the filter chamber 2 to the interior of the cleaning chamber 15, in preparation for subsequent flushing and cleaning.
[0023] Please see Figure 5 and Figure 6 A waterproof protective shell 25 is fixedly installed inside the frame 7, and an electric telescopic rod 26 is fixedly installed inside the waterproof protective shell 25. Multiple sets of connectors 27 are fixedly installed on the filter plate 5, and the output end of the electric telescopic rod 26 is movably connected to the connector 27. When the frame 7 and the filter plate 5 inside it move into the cleaning chamber 15, as the electric telescopic rod 26 inside the waterproof protective shell 25 is activated, its output end will drive the filter plate 5 to move downward, so that the filter plate 5 is separated from the frame 7. Furthermore, by installing the connector 27 and controlling the extension distance of different electric telescopic rods 26, the system can also realize the tilt adjustment of the filter plate 5 after separation, so that the dirt and impurities on the filter plate 5 can be flushed off more effectively.
[0024] Please see Figure 2 and Figure 4The top of the treatment tank 1 is fixedly equipped with an outer shell 17. Inside the outer shell 17, a water tank 18 and multiple sets of water pumps 19 are fixedly installed. The inlet end of the water pump 19 extends into the interior of the water tank 18. The outlet end of the water pump 19 is fixedly installed with a retractable water delivery hose 20, which is located inside the cleaning chamber 15. The cleaning chamber 15 has a water outlet 21 that is movably positioned within it. One end of the retractable water delivery hose 20 extends into the interior of the water outlet 21. The bottom of the water outlet 21 is fixedly equipped with multiple sets of nozzles 28 for rinsing the filter plate 5. Inside the cleaning chamber 15, a second lead screw 22 is rotatably installed. A second lead screw nut 23 is engaged with the second lead screw 22. The exterior of the second lead screw nut 23 is fixedly connected to the top of the water outlet 21. The exterior of the treatment tank 1 is fixedly equipped with a second motor 24. The motor 24 outputs... The outlet end is fixedly connected to one end of the lead screw 22. The water tank 18 serves as a water storage container, providing sufficient water for the entire flushing process. The water pump 19 is responsible for drawing water from the water tank 18 and delivering it to the water outlet 21 in the cleaning chamber 15 through the retractable water delivery hose 20 connected to its outlet end. Finally, the water is evenly sprayed onto the filter plate 5 through multiple sets of nozzles 28 on the water outlet 21. The impact force of the water flow washes away the dirt and impurities attached to the filter plate 5. When the motor 24 drives the lead screw 22 to rotate, the lead screw nut 23 will move along the axial direction of the lead screw 22, thereby driving the water outlet 21, which is installed in the cleaning chamber 15, to move. This achieves flushing and cleaning of different positions of the filter plate 5, so that the cleaning water sprayed by the nozzles 28 on the water outlet 21 can more effectively complete the cleaning work of the filter plate 5.
[0025] Working principle: The treatment box 1 is the main body of the entire device, containing a filter chamber 2 and a cleaning chamber 15. The filter chamber 2 is located inside the treatment box 1 and is used to house the filter plate 5 and treat wastewater. The inlet 3 and outlet 4 are respectively located on the treatment box 1 and cooperate with the filter chamber 2 to realize the inflow and outflow of wastewater. The filter plate 5 is installed inside the filter chamber 2 to filter the wastewater and remove impurities. Through the installation of the frame 7 and the shell 10, when the filter plate 5 needs to be cleaned, the motor 12 inside the shell 10 starts. The motor 12 drives the frame 7 and the filter plate 5 inside it to move along the limiting slide groove 6 inside the treatment box 1, moving from the filter chamber 2 to the inside of the cleaning chamber 15, preparing for subsequent flushing and cleaning work. The electric telescopic rod 26 is activated, and its output end drives the filter plate 5 downward, separating it from the frame 7 and tilting it to better flush away dirt and impurities. Simultaneously, the water pump 19 inside the outer casing 17 and the motor 24 outside the treatment tank 1 are activated. The water pump 19 provides cleaning water, and the motor 24 drives the water outlet 21 to move at a constant speed within the cleaning chamber 15, causing the nozzles 28 on the water outlet 21 to spray cleaning water. The impact force of the water flow washes away the dirt and impurities adhering to the filter plate 5. After cleaning, the electric telescopic rod 26 and the motor 12 are activated again. The electric telescopic rod 26 lifts the filter plate 5 back to its original position, reconnecting it with the frame 7. The motor 12 drives the frame 7 and filter plate 5 back along the limiting slide groove 6. Filter chamber 2 prepares for the next wastewater filtration operation, enabling the entire cleaning process of filter plate 5 to proceed without manual intervention, improving work efficiency and safety, and making the cleaning and maintenance of filter plate 5 simpler and faster. Treatment box 1 is the main structure, used to contain and process various substances. The limiting groove 6 inside treatment box 1 guides and restricts the movement direction and path of frame 7 and its internal filter plate 5, allowing frame 7 and its internal filter plate 5 to move within filter chamber 2 and cleaning chamber 15. Frame 7 is a movable structure, with filter plate 5 movably fitted inside, allowing filter plate 5 to be moved or adjusted as a whole via frame 7. When motor 12 starts, gear 13 at its output end begins to rotate, and through the transmission of chain 14, gear 11... The gear 11 rotates, causing the lead screw 8 to rotate. The rotation of the lead screw 8 causes the lead screw nut 9, which meshes with it, to move axially along the lead screw 8. Since the lead screw nut 9 is fixedly connected to the frame 7, the frame 7 and its internal filter plate 5 also move, moving from the filter chamber 2 to the cleaning chamber 15, preparing for subsequent flushing and cleaning. Once the frame 7 and its internal filter plate 5 have moved into the cleaning chamber 15, the electric telescopic rod 26 inside the waterproof protective shell 25 is activated. Its output end drives the filter plate 5 downwards, separating it from the frame 7. Furthermore, through the installation of the connector 27, by controlling the extension distance of different electric telescopic rods 26, the system can also adjust the tilt of the filter plate 5 after separation.To ensure the effective removal of dirt and impurities from the filter plate 5, the water tank 18 serves as a storage container, providing ample water for the entire rinsing process. The water pump 19 extracts water from the tank 18 and delivers it through a retractable water hose 20 connected to its outlet end to the outlet end 21 within the cleaning chamber 15. Finally, multiple nozzles 28 on the outlet end 21 evenly spray water onto the filter plate 5, using the impact force of the water flow to wash away the dirt and impurities adhering to the filter plate 5. When the motor 24 drives the lead screw 22 to rotate, the lead screw nut 23 moves along the axial direction of the lead screw 22, thereby moving the movable outlet end 21 within the cleaning chamber 15, achieving rinsing and cleaning of different positions on the filter plate 5. This ensures that the cleaning water sprayed by the nozzles 28 on the outlet end 21 more effectively cleans the filter plate 5.
