Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, it relates to a suspended solids removal tank for rural domestic sewage. Background Technology

[0002] Domestic sewage refers to water used by residents in their daily lives, mainly originating from residential and public buildings such as homes, government offices, schools, hospitals, shops, public places, and industrial enterprise restrooms. This sewage includes water discharged from toilets, kitchens, bathrooms, laundry rooms, etc., and contains a relatively high amount of organic matter (such as protein, animal fat, carbohydrates, and ammonia nitrogen), as well as soap, detergents, and pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses). The sewage contains many suspended solids, which can cause water quality deterioration over time.

[0003] In related technologies, a rural domestic sewage suspended solids removal tank (application number: 202420578855.1) uses a barrier channel at the inlet to block large suspended solids in the second collection tank, and uses a suction port to extract suspended solids floating on the water surface.

[0004] The existing technical solutions mentioned above have the following drawbacks: they cannot treat the filtered suspended solids, which requires staff to clean the barrier tank regularly, which is time-consuming and labor-intensive. Furthermore, when extracting suspended solids through the suction port, the suction port cannot be moved, resulting in incomplete treatment of suspended solids on the water surface.

[0034] Example:

[0035] This utility model provides a technical solution: a rural domestic sewage suspended solids removal tank, including a tank body 1, as shown in the figure. Figure 1 and Figure 2 A water inlet pipe 2 is installed on the top side of the pool body 1. A filter frame 3 is connected inside the pool body 1. The outlet of the water inlet pipe 2 is located above the filter frame 3. A pusher frame 4 is installed inside the filter frame 3. The filter frame 3 and the pusher frame 4 are used to filter and collect larger suspended solids in the sewage. A lifting and lowering fixed frame 25 is installed on the top of the pool body 1. An arc-shaped protective shell 26 is connected to the bottom of the fixed frame 25. A trapezoidal scraper 27 is connected to the bottom of the protective shell 26. The protective shell 26 cooperates with the scraper 27. Multiple suction pipes 28 are connected to the top of the protective shell 26. The water inlet ends of the multiple suction pipes 28 all pass through the protective shell 26 and are connected to the top of the inner wall of the protective shell 26. The protective shell 26, scraper 27 and suction pipes 28 are used to collect suspended solids floating on the surface of the sewage. An air flotation machine 13 is installed on one side of the pool body 1. Figure 4The bottom of the inner wall of the pool 1 is connected to a "rice" shaped air supply pipe 14. The output end of the air flotation machine 13 is connected to the air supply pipe 14, and multiple air nozzles 15 are connected to the air supply pipe 14.

[0036] Specifically, such as Figure 5 A frame 7 is connected to the top of the tank body 1. A first screw 8 is rotatably connected inside the frame 7. A first threaded cylinder 9 is threaded onto the first screw 8. A first pusher 10 is connected to the first threaded cylinder 9. The first pusher 10 is slidably connected inside the frame 7. The bottom of the first pusher 10 passes through the frame 7 and is connected to the top of the pusher 4. A placement plate 11 is connected to one side of the tank body 1. A storage box 12 is set on the placement plate 11. The storage box 12 is located on one side of the air flotation machine 13 and cooperates with the filter frame 3. A servo motor 5 is connected to the side of the tank body 1 away from the air flotation machine 13. The output end of motor 5 is connected to a rotating shaft 6. One end of the first screw 8 passes through the frame 7 and is connected to one end of the rotating shaft 6. A worm gear 18 is connected to the rotating shaft 6. Two bearing seats 16 are connected to one side of the pool body 1. A second screw 17 is rotatably connected to the two bearing seats 16. A worm wheel 19 is connected to the end of the second screw 17 near the servo motor 5. The rotating shaft 6 meshes with the worm wheel 19 on the second screw through the worm gear 18. A second threaded cylinder 20 is threadedly connected to the second screw 17. A second pusher frame 21 is connected to the second threaded cylinder 20. A support plate 22 is connected to the top of the second pusher frame 21. Figure 6 and Figure 7 The support plate 22 is located at the top of the pool body 1. Two support frames 23 are connected to the top of the support plate 22. Electric push rods 24 are connected to the bottom of each support frame 23. The top of the fixed frame 25 is connected to the output end of the two electric push rods 24. A conveying pipe 29 is connected to one side of the fixed frame 25. One end of multiple suction pipes 28 is connected to the conveying pipe 29. One end of the conveying pipe 29 is connected to a telescopic pipe 30. Figure 3 A water pump 31 is connected to one side of the pool body 1. The water pump 31 is located between the air flotation machine 13 and the collection box 12.

The output end of the water pump 31 is connected to the discharge pipe 32, and the other end of the discharge pipe 32 is located inside the collection box 12. By adopting the above technical solution, the first screw 8, the first threaded cylinder 9 and the first pusher 10 drive the pusher 4 to move back and forth in the filter frame 3, thereby continuously pushing the suspended matter in the filter frame 3 into the collection box 12 for collection. The second screw 17, the second threaded cylinder 20 and the second pusher 21 drive the pusher 4 to move back and forth when the servo motor 5 drives it, thereby driving the protective shell 26 and the scraper 27 to move back and forth on the water surface, thereby improving the cleaning effect of suspended matter on the water surface.

[0037] The working principle of this utility model is as follows: During use, the operator places domestic sewage into the tank 1 through the inlet pipe 2. The sewage then flows through the inlet pipe 2 into the filter frame 3, where it is filtered to remove larger suspended solids. The filtered sewage then falls back into the tank 1. For the suspended solids remaining in the filter frame 3, power is supplied to the servo motor 5. The servo motor 5 drives the rotating shaft 6 to rotate, which in turn drives the first screw 8 to rotate within the frame 7. This causes the first threaded cylinder 9 to move along the first screw 8. The first pusher 10, acting as a limit, moves the first threaded cylinder 9 towards the storage box 12, causing the bottom pusher 4 to move along the filter frame. The servo motor 5 moves towards the storage box 12, pushing the suspended matter in the filter frame 3. As the first screw 8 continues to rotate, it moves the pusher 4 to one side of the filter frame 3. The servo motor 5 stops working, causing the first screw 8 to stop rotating. At this time, the suspended matter pushed by the pusher 4 is discharged through one side of the filter frame 3 and falls into the storage box 12. After the suspended matter falls into the storage box 12, the servo motor 5 works, driving the rotating shaft 6 to rotate in the opposite direction, causing the first screw 8 to rotate in the opposite direction within the frame 7, causing the first pusher 10 to slide in the opposite direction within the frame 7, and causing the pusher 4 at the bottom to slide in the opposite direction and reset within the filter frame 3. After the filter frame 3 has been filtering for a period of time, this step is repeated to continuously push and clean the filter frame 3, causing the suspended matter to fall into the pool 1. Wastewater is treated by an air flotation machine 13, which, in conjunction with an air supply pipe 14, sprays tiny bubbles at nozzles 15. These bubbles adhere to suspended particles, whose density is less than that of the wastewater. Therefore, due to buoyancy, the suspended particles float to the surface. An electric push rod 24 extends or retracts, raising or lowering the bottom mounting bracket 25, which in turn raises or lowers the bottom protective shell 26 and scraper 27. Adjustments are made to different water levels by inserting the scraper 27 into the water, slightly below the surface, until the top of the scraper 27 is level with the water surface. A suction pump 31 pumps air from the delivery pipe 29, and a suction pipe 28 extracts air from between the protective shell 26 and the scraper 27, causing them to float. The space between them is under negative pressure, allowing suspended matter to pass through the protective shell 26 and scraper 27 into the suction pipe 28. From there, it enters the conveying pipe 29, then the telescopic pipe 30 and the water pump 31, finally being discharged through the discharge pipe 32 at the output end of the water pump 31 into the collection box 12. When the servo motor 5 drives the rotating shaft 6 to rotate, the worm gear 18 on the shaft 6 meshes with the worm wheel 19, causing the second screw 17 to rotate on the bearing seat 16. The second push frame 21 limits the movement of the second threaded cylinder 20 on the second screw 17, which in turn moves the support plate 22 on the pool body 1, causing the bottom protective shell 26 and scraper 27 to move.When the pusher 4 moves to one side of the filter frame 3, the protective shell 26 and scraper 27 move to the side above the air supply pipe 14. When the servo motor 5 drives the rotating shaft 6 to reverse, the worm gear 18 on the rotating shaft 6 meshes with the worm wheel 19 to reverse, causing the second screw 17 to rotate in the opposite direction. This, in turn, causes the second pusher 21 to move in the opposite direction via the second threaded cylinder 20, which in turn causes the support plate 22 on the pool body 1 to move in the opposite direction. This, in turn, causes the protective shell 26 and scraper 27 at the bottom to move in the opposite direction on the water surface. This continues until the first screw 8 drives the pusher 4 to move to the other side of the filter frame 3, at which point the protective shell 26 and scraper 27 move to the other side above the air supply pipe 14. This completes the back-and-forth movement of the protective shell 26 and scraper 27 on the water surface to clean and collect suspended solids, resulting in better cleaning performance.

[0038] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
