[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: a dosing control device for sewage treatment, including a support 1; a sewage tank 2 is installed on the top of the support 1, a chemical storage tank 3 is installed on the top of the sewage tank 2, a chemical injection port 4 is installed on the top of the chemical storage tank 3, a stirring assembly 5 is installed inside the sewage tank 2, a motor 6 is installed at the bottom of the sewage tank 2, the output end of the motor 6 is fixed to the stirring assembly 5, an inlet pipe 7 is installed on one side of the sewage tank 2, an outlet pipe 8 is installed on the other side of the sewage tank 2, a control device 9 is installed on the surface of the sewage tank 2, a delivery pipe 10 is installed on one side of the chemical storage tank 3, a metering pump 11 is installed at the other end of the delivery pipe 10, a conical check valve 12 is installed at the outlet of the metering pump 11, and a delivery pipe 13 is fixed at the end of the conical check valve 12 away from the metering pump 11. A filter assembly is provided on the surface of the delivery pipe 10. The filter assembly is located at the front end of the metering pump 11. The filter assembly includes a filter shell 14 fixed to the surface of the delivery pipe 10. A filter screen 15 is slidably installed inside the filter shell 14. A fixing shell 16 is fixed to the top of the filter shell 14. A fixing mechanism for installing the filter screen 15 is provided inside the fixing shell 16. Through the filter assembly, the chemicals entering the delivery pipe 10 and the metering pump 11 can be filtered to prevent impurities, crystals or precipitates contained in the chemicals from entering the delivery pipe 10 and the metering pump 11, causing blockage of the delivery pipe 10 and the metering pump 11, which would affect the operation of the equipment. At the same time, the fixing mechanism facilitates the disassembly and replacement of the filter screen 15 by the staff, thereby improving the practicality of the chemical dosing control device for sewage treatment.

[0023] Reference Figure 5As shown in this embodiment: the fixing mechanism includes a knob 17 threaded to the side wall of the fixing housing 16. A transmission block 18 is fixed to one end of the knob 17 inside the fixing housing 16. A pressure plate 19 slides inside the fixing housing 16. The pressure plate 19 is located on one side of the transmission block 18, and an insertion rod 20 is fixed to the other side of the pressure plate 19. A slot 21 matching the insertion rod 20 is opened on the top of the filter screen 15. A spring 22 is sleeved on the surface of the insertion rod 20. One end of the spring 22 is fixed to the inside of the fixing housing 16, and the other end of the spring 22 is fixed to the pressure plate 19. By rotating the knob 17, the transmission block 18 is driven to rotate and move away from the pressure plate 19. The pressure plate 19 is not squeezed and is pushed by the spring 22, which drives the insertion rod 20 to disengage from the inside of the slot 21, releasing the fixing of the filter screen 15. At this time, the filter screen 15 can be taken out from the inside of the filter housing 14, achieving the effect of easy disassembly and replacement of the filter screen 15. The operation process is simple.

[0024] Reference Figure 5 As shown in this embodiment: guide grooves 24 are provided on both sides inside the fixed shell 16, and guide blocks 23 matching the guide grooves 24 are fixed at both ends of the pressure plate 19. The guide blocks 23 and guide grooves 24 limit the pressure plate 19, making the pressure plate 19 more stable during movement and preventing the pressure plate 19 from shifting during movement.

[0025] Reference Figure 5 As shown in this embodiment: the surface of the long shaft end of the knob 17 is fitted with an anti-slip pad 25. The anti-slip pad 25 can seal the gap between the knob 17 and the fixed shell 16, preventing external impurities from entering the interior of the fixed shell 16 through the gap, damaging the fixing mechanism, affecting the use of the fixing mechanism, and increasing the firmness between the knob 17 and the fixed shell 16.

[0026] Reference Figure 5 As shown in this embodiment: a sealing block 26 is fixed to the top of the filter screen 15, and a sealing groove 27 matching the sealing block 26 is opened on the top of the filter shell 14. Through the sealing block 26 and the sealing groove 27, the gap between the filter screen 15 and the filter shell 14 can be sealed, which further improves the sealing performance of the dosing control device for sewage treatment and prevents the agent from seeping out from the gap between the filter screen 15 and the filter shell 14, thus avoiding the waste of agent.

[0027] Reference Figures 2-3As shown in this embodiment: the motor 6 and the metering pump 11 are electrically connected to the control device 9. The control device 9 controls the start and stop of the motor 6 and the metering pump 11. When the device needs to be used, the control device 9 first starts the motor 6. The output end of the motor 6 drives the stirring assembly 5 to rotate, mixing the agent and sewage in the sewage tank 2, improving the mixing uniformity of the agent and sewage, and improving the sewage treatment effect. At the same time, the control device 9 controls the metering pump 11 to start. The metering pump 11 discharges the mixed agent through the delivery pipe 10 and the conical check valve 12 from the outlet pipe 13 for use. The conical check valve 12 is provided to prevent the agent from flowing back and causing waste.

[0028] Working Principle: The user can filter the chemicals entering the delivery pipe 10 and metering pump 11 through the set filter components, preventing impurities, crystals, or precipitates in the chemicals from entering these pipes and pumps, thus avoiding blockages and affecting equipment operation. The fixed mechanism facilitates the disassembly and replacement of the filter screen 15, improving the practicality of this wastewater treatment dosing control device. Rotating the knob 17 drives the transmission block 18 to rotate, moving it away from the pressure plate 19. While the pressure plate 19 is no longer compressed, it is pushed by the spring 22, causing the insertion rod 20 to disengage from the slot 21, releasing the filter screen 15. At this point, the filter screen 15 can be removed from the filter housing 14, facilitating its disassembly and replacement. The device is effective and easy to operate. The guide block 23 and guide groove 24 limit the movement of the pressure plate 19, ensuring smoother movement and preventing deviation. The anti-slip pad 25 seals the gap between the knob 17 and the fixed housing 16, preventing external impurities from entering and damaging the fixing mechanism, thus increasing its usability. The sealing block 26 and sealing groove 27 seal the gap between the filter screen 15 and the filter housing 14, further improving the sealing performance of the wastewater treatment dosing control device and preventing leakage of chemicals, thus avoiding waste.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
