[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0040] Reference Figures 1-3An embodiment of this utility model provides a graded separation and sedimentation device for wastewater recycling, comprising a base plate 1, a filter box 2 disposed on the upper surface of the base plate 1, a water pump 3 disposed on the outer wall of the filter box 2, a sedimentation tank 4 fixedly connected to the outer wall of the water pump 3, a water pump 5 disposed on the outer wall of the sedimentation tank 4, a sedimentation tank 6 fixedly connected to the outer wall of the water pump 5, a storage box 8 disposed on the outer wall of the sedimentation tank 4, a water storage tank 7 disposed on the outer wall of the sedimentation tank 6, a fixing frame 9 fixedly connected to the outer wall of the sedimentation tank 6, a fixing frame 10 fixedly connected to the upper surface of the sedimentation tank 6, a motor 11 disposed inside the fixing frame 9, a transmission assembly disposed at the output end of the motor 11, a connecting column 16 disposed inside the transmission assembly, a stirring plate 19 fixedly connected to the outer wall of the connecting column 16, a fixing column 18 rotatably connected to the outer wall of the connecting column 16, a bevel gear 14 disposed at the tooth end of the transmission assembly, and a connecting column 15 fixedly connected to the outer wall of the bevel gear 14.
[0041] Specifically, filter box 2 is used to filter larger particulate impurities in sewage. Then, water pump 3 transports the pre-filtered sewage to sedimentation tank 4. The sewage in sedimentation tank 4 flows horizontally, causing suspended solids to settle to the bottom of sedimentation tank 4. Water pump 5 is used to transport the pre-sedimented sewage to sedimentation tank 6. By adding flocculant to sedimentation tank 6, fine particles are aggregated into larger flocs, accelerating sedimentation. After adding flocculant, motor 11 is turned on to drive the transmission component to rotate. When the transmission component rotates, the connecting column 16 is driven to rotate due to the fixing action of the transmission component and connecting column 16, which in turn drives the stirring plate 19 to rotate. At the same time, the rotation of the transmission component also drives the connecting column 15 to rotate in the opposite direction to the connecting column 16. When the connecting column 15 rotates, the stirring plate 19 is driven to rotate due to the fixing action of the connecting column 15 and the stirring plate 19. Through the rotation of connecting column 15 and connecting column 16, the sewage and flocculant are thoroughly mixed, improving the reaction speed of sewage and flocculant.
[0042] Reference Figures 1-3The transmission assembly includes a bevel gear 12, the outer wall of which is connected to the output end of the motor 11. The tooth ends of bevel gear 12 mesh with a bevel gear 13. The outer wall of connecting column 16 is fixedly connected to the interior of bevel gear 13. The outer wall of bevel gear 13 is rotatably connected to the interior of the fixing frame 10. The tooth ends of bevel gear 12 mesh with the tooth ends of bevel gear 13. The lower surface of water pump 3 is fixedly connected to the upper surface of the base plate 1. The lower surface of sedimentation tank 4 is fixedly connected to the upper surface of the base plate 1. The lower surface of water pump 5 is fixedly connected to the upper surface of the base plate 1. The lower surface of sedimentation tank 6 is fixedly connected to... The upper surface of the base plate 1 and the lower surface of the storage box 8 are fixedly connected to the upper surface of the base plate 1, and the lower surface of the water storage tank 7 is fixedly connected to the upper surface of the base plate 1; the outer wall of the transmission component is rotatably connected to the inside of the second fixed frame 10, the outer wall of the fixed column 18 is fixedly connected to the inside of the second sedimentation tank 6, the outer wall of the first connecting column 15 is rotatably connected to the inside of the second fixed frame 10, the outer wall of the second connecting column 16 is rotatably connected to the inside of the first connecting column 15, the outer wall of the second connecting column 16 is rotatably connected to the inside of the second fixed frame 10, and the outer wall of the stirring plate 19 is fixedly connected to the outer wall of the first connecting column 15; a flow channel 17 is provided inside the stirring plate 19;
[0043] Specifically, when the motor 11 is running, it will drive the first bevel gear 12 to rotate, which in turn drives the second bevel gear 13 to rotate. When the second bevel gear 13 rotates, it will drive the second connecting column 16 to rotate through the fixing action of the second bevel gear 13 and the second connecting column 16. At the same time, the first bevel gear 12 will also drive the third bevel gear 14 to rotate, which in turn drives the first connecting column 15 to rotate. The diversion channel 17 is used to change the direction of sewage flow to ensure that the sewage can be evenly mixed with the added flocculant.
[0044] Reference Figure 1 , Figure 4 and Figure 5 The filter box 2 is equipped with a filter screen 20 inside. A connecting frame 21 is fixedly connected to the upper surface of the filter screen 20. A rotating plate 23 is provided on the outer wall of the connecting frame 21. A rotating assembly is provided inside the rotating plate 23. The outer wall of the rotating assembly is rotatably connected to the inside of the filter box 2. The lower surface of the connecting frame 21 is provided on the outer wall of the filter box 2. The rotating assembly includes a rotating block 22. The outer wall of the rotating block 22 is fixedly connected to the inside of the rotating plate 23. An anti-slip groove 24 is provided inside the rotating block 22. The outer wall of the rotating block 22 is rotatably connected to the inside of the filter box 2. Sludge scrapers are provided inside the sedimentation tank 4 and the sedimentation tank 6.
[0045] Specifically, the sludge scraper is used to clean the solid impurities at the bottom of sedimentation tank 4 and sedimentation tank 6. The filter screen 20 is used to filter larger particulate impurities in the sewage. When the filter screen 20 needs to be disassembled and cleaned, first rotate the rotating block 22. The anti-slip groove 24 is used to facilitate the operator to rotate the rotating block 22. When the rotating block 22 rotates, the rotating plate 23 will be driven to rotate by the fixing action of the rotating block 22 and the rotating plate 23, further aligning it with the hole opened inside the connecting frame 21. At this time, the connecting frame 21 is pulled upward to move the filter screen 20 upward, thereby achieving the effect of quickly disassembling the filter screen 20 and facilitating the subsequent cleaning of the filter screen 20 by the operator.
[0046] Working principle: Wastewater first passes through the filter screen 20 inside the filter box 2 to remove larger particulate impurities. Then, it is pumped to the sedimentation tank 4 by the water pump 3. In the sedimentation tank 4, the wastewater flows horizontally, further allowing suspended solids to settle naturally to the bottom of the sedimentation tank 4. The sediment is then scraped by a sludge scraper and placed into the collection box 8 for subsequent centralized treatment. Subsequently, the water pump 5 pumps the upper layer of clear water to the sedimentation tank 6. By adding flocculant to the sedimentation tank 6, fine particles aggregate into larger flocs and settle to the bottom of the sedimentation tank 6. By turning on the motor 11, the bevel gears 12 and 13 rotate, which in turn rotates the connecting column 16. While the bevel gear 12 rotates, it also drives the bevel gear 3 14 to rotate the connecting column 15 in the opposite direction, further driving the stirring plate 19 to stir the wastewater and flocculant in both directions, ensuring uniform mixing. This improves the flocculation reaction rate, accelerates the settling of fine particles, and thus improves the water purification efficiency.
[0047] When the filter screen 20 needs to be cleaned, first rotate the rotating block 22 to drive the rotating plate 23 to rotate, so that it is aligned with the hole opened inside the connecting frame 21, and further realize the removal of the limit on the connecting frame 21. At this time, pull the connecting frame 21 upward to remove the filter screen 20 from the filter box 2, thereby achieving quick disassembly of the filter screen 20, making it convenient for operators to clean the filter screen 20, and avoiding the effect of impurities accumulating and causing a decrease in filtration efficiency.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
