Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a sewage treatment tank for sewage treatment. Background Technology

[0002] In the treatment of urban and rural domestic sewage and food processing wastewater, sewage treatment ponds are the core structures for water purification, where sewage undergoes biological or sedimentation treatment upon entering the treatment ponds.

[0003] Currently, a grid or filter plate is installed at the inlet of the treatment tank to intercept wastewater through the gaps between the grid bars or filter holes. Although this method is simple in structure and low in cost, it has a significant drawback in actual operation: The filter traps are difficult to clean and can easily become a source of secondary pollution. Solid waste intercepted by the grid or filter plate will quickly accumulate on its water-facing surface. As the accumulation thickness increases, it will not only seriously hinder the flow of water and cause poor water intake, but also cause the liquid inlet pipe to withstand huge pressure. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wastewater treatment tank for wastewater treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wastewater treatment tank for wastewater treatment includes a tank body, a through groove is provided on one side of the tank body, a shell communicating with the through groove is fixedly connected to the outer wall of one side of the tank body, and a spraying assembly is provided on the top of the shell.

Steel ropes are fixedly connected to the bottom positions of both sides of the frame away from the fixed plate. Hooks are fixedly connected to the bottom ends of the steel ropes. Fixed frames are fixedly connected to the inner walls of both sides of the shell. Fixed rods are fixedly connected to the top of the fixed frames. The hooks hook the fixed rods and are locked by a rotatable anti-detachment baffle on the hooks. A filter plate is fixed inside the frame, and a second baffle is installed at the bottom of the housing via a detachable connecting assembly.

[0006] As a further embodiment of this utility model, the connecting assembly includes two fixing blocks, which are fixed to the outer walls of both sides of the treatment tank body by bolts. Threaded grooves are opened in the two fixing blocks. Protrusions are fixedly connected to both sides of the second baffle, and fixing bolts are inserted into the protrusions. The threaded grooves are threadedly connected to the fixing bolts.

[0007] As a further embodiment of this utility model, the spraying assembly includes a first liquid inlet, which is located at the top of the housing. A first liquid inlet pipe is fixedly connected inside the first liquid inlet, and the bottom end of the first liquid inlet pipe passes through the first liquid inlet and is fixedly connected to a manifold. Multiple nozzles are fixedly connected to the bottom of the manifold.

[0008] As a further embodiment of this invention, the nozzle is located above the filter plate.

[0009] As a further improvement of this utility model, a check valve is fixed on the first inlet pipe.

[0010] As a further embodiment of this utility model, a second liquid inlet is provided on one side of the housing, and a second liquid inlet pipe is fixedly connected to the second liquid inlet.

[0011] As a further embodiment of this utility model, the fixing plate and the first baffle located on the same side of the treatment pool body form an L-shaped structure.

[0012] The beneficial effects of this utility model are as follows: 1. In this utility model, the filter plate filters the garbage and impurities in the sewage, ensuring that the filtered sewage can smoothly enter the treatment tank for subsequent treatment.

[0018] Reference Figures 1-4 A wastewater treatment tank for wastewater treatment includes a treatment tank body 3, a through groove is provided on one side of the treatment tank body 3, and a shell 4 communicating with the through groove is fixed to the outer wall of one side of the treatment tank body 3 by bolts. A spraying assembly is provided on the top of the shell 4. The spraying assembly includes a first liquid inlet located at the top of the housing 4. A first liquid inlet pipe 1 is fixedly connected to the first liquid inlet. The bottom end of the first liquid inlet pipe 1 passes through the first liquid inlet and is fixedly connected to a manifold 11. An external cleaning liquid supply device is connected and fixedly connected to the first liquid inlet pipe 1, allowing the cleaning liquid to enter the manifold 11 through the first liquid inlet pipe 1. Multiple nozzles 10 are fixedly connected to the bottom of the manifold 11. The manifold 11 serves to distribute the liquid evenly to the multiple nozzles 10. The nozzles 10 are located above the filter plate 14. The cleaning liquid in the manifold 11 is sprayed onto the filter plate 14 under high pressure through the nozzles 10, thus cleaning the filter plate 14. A check valve 2 is fixed on the first liquid inlet pipe 1, which prevents the liquid in the housing 4 from flowing back. The inner walls of both sides of the treatment tank body 3 are fixed with fixing plates 12 by bolts. The bottom of the fixing plates 12 is welded with a first baffle 13. A frame 15 is placed on the two first baffles 13, and the two sides of the frame 15 are in contact with the fixing plates 12. The fixing plates 12 and the first baffles 13 on the same side of the treatment tank body 3 form an L-shaped structure. The first baffles 13 and the fixing plates 12 support and position the frame 15. A filter plate 14 is fixed inside the frame 15. The passage is located above the filter plate 14. The sewage entering the shell 4 passes through the filter plate 14. The filter plate 14 filters the garbage and impurities in the sewage and allows the filtered sewage to enter the treatment tank body 3 through the passage, which facilitates the subsequent treatment of the sewage in the treatment tank body 3 by the staff. Steel ropes 19 are welded to the bottom of both sides of the frame 15 away from the fixed plate 12. Hooks 16 are welded to the bottom of the steel ropes 19. The hooks 16 are self-locking hooks, including a hanging ring and a rotatable anti-detachment baffle. Fixing frames 18 are fixed to the inner walls of both sides of the shell 4 by bolts. Fixing rods 17 are welded to the top of the fixing frames 18. The hanging ring of the hook 16 hooks the fixing rod 17 and the fixing rod 17 is pulled by the rotatable anti-detachment baffle on the hook 16. The height position of the frame 15 can be limited, so as to prevent the sewage from moving upward along the shell 4 and causing the frame 15 to move upward and detach from the first baffle 13 and the fixed plate 12, thereby improving the stability of the filtration process. Rotate the anti-detachment baffle on the hook 16 to unlock it, separating the hook 16 from the fixing rod 17 and the fixing frame 18. At this time, the frame 15 is no longer restricted. The worker moves the frame 15 horizontally upward so that it moves out of the first baffle 13 and the fixing plate 12. Then rotate the frame 15 so that the frame 15 tilts until the two first baffles 13 no longer block the frame 15. Then the worker moves the frame 15 downward at this tilt angle until the frame 15 drives the filter plate 14 out of the housing 4, thus completing the disassembly of the filter plate 14.

[0019] A second baffle 6 is installed at the bottom of the housing 4 via a detachable connecting assembly. The connecting assembly includes two fixing blocks 7, which are fixed to the outer walls of both sides of the treatment tank body 3 by bolts. Threaded grooves 9 are opened in the two fixing blocks 7. Protrusions are welded on both sides of the second baffle 6, and fixing bolts 8 are inserted into the protrusions. The threaded grooves 9 are threadedly connected to the fixing bolts 8. The second baffle 6 is sealed to the bottom of the housing 4 through a rubber sealing gasket. By rotating the fixing bolts 8, they are moved out of the threaded grooves 9. The operator moves the second baffle 6 downwards, so that the bottom of the housing 4 is no longer obstructed.

[0020] A second liquid inlet is provided on one side of the housing 4. A second liquid inlet pipe 5 is fixedly connected to the second liquid inlet. The second liquid inlet pipe 5 is located at the bottom of the filter plate 14. The second liquid inlet pipe 5 is connected to an external water pump. The external water pump draws sewage from the external sewage equipment and enters the housing 4 through the second liquid inlet pipe 5.

[0021] Working principle: When primary filtration of wastewater is required, First, connect the second inlet pipe 5 to the external water pump. The external water pump draws out the sewage from the external sewage equipment and enters the housing 4 through the second inlet pipe 5. Filtration process: Wastewater entering the shell 4 passes through the filter plate 14, which filters out garbage and impurities in the wastewater. The filtered wastewater then enters the treatment tank body 3 through the channel, facilitating further treatment of the wastewater in the treatment tank body 3 by the staff.

[0022] When it is necessary to disassemble filter plate 14: Rotate the fixing bolt 8 to move it out of the threaded groove 9. The worker moves the second baffle 6 downward so that the bottom of the housing 4 is no longer blocked. At this time, the worker can remove the garbage and impurities that have settled on the second baffle 6. At this time, the bottom of the housing 4 is open. The worker manually or with auxiliary tools reaches into the housing 4 from the bottom opening, rotates the anti-detachment baffle on the hook 16 to release the lock, and separates the hook 16 from the fixing rod 17 and the fixing frame 18. At this time, the frame 15 is no longer restricted. The worker moves the frame 15 horizontally upward to move it out of the first baffle 13 and the fixing plate 12. Then, the worker rotates the frame 15 to tilt it until the two first baffles 13 no longer block the straight distance on both sides of the frame 15. Then, the worker moves the frame 15 downward at this tilt angle until the frame 15 drives the filter plate 14 out of the housing 4, thus completing the disassembly of the filter plate 14.

[0023] Cleaning filter plate 14: The external cleaning fluid supply device is connected and fixed to the first inlet pipe 1, so that the cleaning fluid enters the manifold 11 through the first inlet pipe 1 and is sprayed onto the filter plate 14 under high pressure through the nozzle 10, thereby cleaning the filter plate 14.
