Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment, and in particular to an automatic dosing device for wastewater treatment. Background Technology

[0002] In the fields of industrial production and environmental protection, wastewater treatment is a crucial link in ensuring the ecological environment and achieving sustainable development. Chemical dosing, as an important step in the wastewater purification process, directly affects the final water quality compliance. By adding specific liquid chemicals to wastewater, pollutants can be neutralized, flocculated, or precipitated, thereby reducing the degree of pollution. Therefore, related chemical dosing devices are widely used in various wastewater treatment systems.

[0003] In existing technologies, the dosing process in wastewater treatment largely relies on manual operation to control the opening, closing, and flow rate of liquid chemicals. Operators need to adjust these parameters based on experience or simple metering tools. This not only increases labor costs but also makes the dosing flow rate inaccurate due to human error, delayed operation, and other factors, thus affecting the wastewater treatment effect and reducing the efficiency and controllability of the dosing process. Furthermore, components such as the rotating plates that come into contact with the chemicals in existing dosing devices are often designed as a single unit. When the rotating plates are damaged due to prolonged contact with chemicals or require cleaning due to surface impurities, the entire related component often needs to be disassembled and replaced. This is not only cumbersome but also consumes a significant amount of maintenance time. The complete replacement method significantly increases the maintenance cost of the equipment and is not conducive to its long-term efficient operation. To address these technical problems, this application proposes an automatic dosing device for wastewater treatment. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-4 This utility model provides an embodiment of an automatic dosing device for wastewater treatment, comprising a tank 1. A second motor 9 is installed on the outer wall of the bottom end of the tank 1. A second bevel gear 19 is fixedly connected to the drive end of the second motor 9. A first bevel gear 18 is meshed with the outer wall of the second bevel gear 19. A rotating roller 12 is fixedly connected to the top end of the first bevel gear 18. A fixing assembly includes a second threaded block 17 fixedly connected to the top end of the rotating roller 12. A threaded ring 16 is threadedly connected to the outer wall of the second threaded block 17. A first threaded block 15 is threadedly connected to the inner wall of the threaded ring 16. A rotating plate 13 is fixedly connected to the bottom end of the first threaded block 15. The left side of the tank 1... A dosing pipe 6 is fixedly connected to the outer side wall. A connecting block 8 is fixedly connected to the left side of the dosing pipe 6. A motor 7 is installed inside the connecting block 8. The threaded assembly includes a bidirectional threaded rod 23 connected to the drive end of the motor 7. Two moving blocks 22 are threadedly connected to the outer wall of the bidirectional threaded rod 23. A sealing plate 20 is fixedly connected to the outer wall of the left side of the moving block 22. Sealing rings 21 are provided on the outer walls of the left and right sides of the connecting block 8. A filter box 11 is slidably connected to the inner wall of the tank body 1. A fixing block 3 is fixedly connected to the outer wall of the right side of the tank body 1. A rotating block 4 is rotatably connected to the inner wall of the fixing block 3. A cover 5 is fixedly connected to the bottom end of the rotating block 4.

[0026] Specifically, when using the device, the wastewater to be treated is first discharged into the tank 1 through the water supply pipe 2. The filter box 11 inside the tank 1 filters out large particles in the wastewater. Next, the dosing pipe 6 is connected to the external liquid medicine. The motor 7 is turned on, and its drive end drives the bidirectional threaded rod 23 to rotate, causing the two moving blocks 22 threaded to the outer wall of the bidirectional threaded rod 23 to move in opposite directions. This causes the two sealing plates 20 to separate, creating a gap, thereby opening the seal of the dosing pipe 6 and allowing the medicine to enter the tank 1. This design not only allows the addition of liquid medicine to be turned on and off at any time, but also controls the gap between the two sealing plates 20 by moving the moving blocks 22 driven by the motor 7, thereby controlling the flow rate of the medicine and making the dosing process more convenient. Afterwards, the motor 9 is turned on, and its drive end drives the rotating roller 12 to rotate through the bevel gear 19 and bevel gear 18, which in turn drives the rotating plate 13 to rotate. The wastewater and medicine in tank 1 are thoroughly stirred to improve the wastewater treatment effect. After the wastewater in tank 1 is treated, the cover 5 can be opened along the axis of the fixed block 3 by rotating block 4. Then, the threaded ring 16 is rotated to make the threaded block 17 and the threaded block 15 lose their threaded fixing effect, thereby detaching the rotating plate 13 from the outer wall of the rotating roller 12. This allows the rotating plate 13 that needs to be cleaned or replaced to be processed. The rotating plate 13 adopts an independent design, so only the damaged parts can be replaced without replacing the whole plate. After replacement, the rotating plate 13 is inserted into the rotating roller 12 along the sliding groove 14. When fully inserted, the threaded block 15 and the threaded block 17 at its top will be connected. The threaded ring 16 is then used to fix the two threads, realizing the quick replacement of the rotating plate 13. At the same time, when the rotating roller 12 rotates, the protective cover at the top of the cover 5 will protect the threaded ring 16 and other components to prevent the wastewater from corroding them.

[0027] Reference Figures 3-5 The inner wall of the tank 1 is provided with at least two sliding grooves 10. The filter box 11 moves up and down on the inner wall of the tank 1 through the sliding grooves 10 to achieve the effect of replacement. At least two water supply pipes 2 are fixedly connected to the outer wall of the tank 1. The position of the water supply pipes 2 is consistent with the position of the filter box 11, which facilitates the filtration of large particles of sewage inside the water supply pipes 2. The outer wall of the rotating roller 12 is provided with at least two sliding grooves 14. The rotating plate 13 moves up and down on the outer wall of the rotating roller 12 through the sliding grooves 14. The connecting block 8 is provided with a guide groove. The moving block 22 moves inside the connecting block 8 through the guide groove. The connecting block 8 is provided with a sealing ring 21. The outer wall of the sealing ring 21 is fixedly connected to the dosing pipe 6 to facilitate the sealing of the liquid medicine inside the dosing pipe 6.

[0028] Specifically, the inner wall of the tank 1 is provided with at least two sliding grooves 10, through which the filter box 11 can move up and down on the inner wall of the tank 1, thereby achieving convenient replacement; at least two water supply pipes 2 are fixedly connected to the outer wall of the tank 1, and the position of the water supply pipes 2 corresponds to the filter box 11. This design facilitates the effective filtration of large particles in the sewage discharged from the water supply pipes 2 by the filter box 11; the outer wall of the rotating roller 12 is provided with at least two sliding grooves 14, and the rotating plate 13 can move up and down on the outer wall of the rotating roller 12 through the sliding grooves 14, which facilitates the installation and disassembly of the rotating plate 13; the connecting block 8 is provided with a guide groove, and the moving block 22 moves inside the connecting block 8 with the help of the guide groove, ensuring the stable transmission of the dosing pipe 6 switch and flow control; at the same time, the connecting block 8 is also provided with a sealing ring 21, and the outer wall of the sealing ring 21 is fixedly connected to the dosing pipe 6. This structure is conducive to reliably sealing the liquid medicine inside the dosing pipe 6, preventing the liquid medicine from leaking, and improving the stability and sealing of the device operation.

[0029] Working Principle: In operation, the wastewater to be treated is discharged into the tank 1 through the water supply pipe 2. The filter box 11 inside the tank 1 filters out large particles in the wastewater. Then, the dosing pipe 6 is connected to an external liquid drug, allowing the drug to flow into the tank 1. Next, motor 7 is activated, causing its drive end to rotate the bidirectional threaded rod 23. This causes the two bidirectional threaded rods 23, threaded onto the outer wall of the bidirectional threaded rod 23, to move in opposite directions, opening the seal on the dosing pipe 6 and allowing the drug to enter the tank 1. This allows for easy opening and closing of the added liquid drug. Furthermore, the movement of the moving block 22 driven by motor 7 allows for control of the drug flow rate, making the dosing process more convenient. Finally, motor 9 is activated, causing its drive end to rotate the rotating roller 12 via bevel gear 19 and bevel gear 18, thereby driving the rotating plate 13 to... The rotating mechanism thoroughly agitates the wastewater and chemicals inside tank 1, improving wastewater treatment efficiency. After all the wastewater inside tank 1 has been treated, the cover 5 can be opened along the axis of the fixed block 3 by rotating block 4. Subsequently, rotating threaded ring 16 causes threaded block 2 17 and threaded block 15 to lose their threaded fixing effect, allowing rotating plate 13 to detach from the outer wall of rotating roller 12. This allows for cleaning or replacement of rotating plate 13, and rotating plate 13 is designed as a single, independent unit. Damaged parts can be replaced without replacing the entire unit. After replacement, the rotating plate 13 is reinserted into the rotating roller 12 along the sliding groove 14. When the rotating plate 13 is fully inserted, the threaded block 15 and threaded block 17 at its top end will connect and then be threaded together by the threaded ring 16. This allows for quick replacement of the rotating plate 13. When the rotating roller 12 rotates, the protective cover at the top of the cover 5 will protect the threaded ring 16 and other components, preventing wastewater from corroding them.

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.
