[0031] Referring to Figure 3 ,Figure 4 A vertically arranged rotating shaft 4 is rotatably connected to the inner wall of the solid feeding box 2. An extrusion mechanism is provided inside the solid feeding box 2. The extrusion mechanism includes a turntable 5 and a fixed plate 6. Both the surface of the turntable 5 and the surface of the fixed plate 6 are provided with through holes 9 for passing solid powder agents. The bottom of the turntable 5 and the top of the fixed plate 6 are in contact. Both the bottom of the turntable 5 and the top of the fixed plate 6 are provided with extrusion surfaces 10. The extrusion surfaces 10 are composed of multiple annular protrusions arranged at equal intervals. The spring 8 at the bottom of the fixed plate 6 provides elastic support to ensure that the turntable 5 and the fixed plate 6 are always in close contact.

[0032] Reference Figure 3 , Figure 4 The turntable 5 is fixedly connected to the outer wall of the rotating shaft 4 and rotatably connected to the inner wall of the solid feeding box 2. The fixed plate 6 is slidably connected to the inner wall of the solid feeding box 2. The fixed plate 6 can only slide up and down relative to the inner wall of the solid feeding box 2. The fixed plate 6 itself cannot rotate. A spring 8 is fixedly connected to the bottom of the fixed plate 6. A limit ring 7 is fixedly connected to the bottom of the spring 8. By setting the spring 8, an upward elastic force is applied to the fixed plate 6. The limit ring 7 is fixedly connected to the inner wall of the solid feeding box 2. The limit ring 7 is used to support the fixed plate 6 and the spring 8 to prevent the fixed plate 6 and the spring 8 from falling out of the solid feeding box 2.

[0033] Reference Figure 1 , Figure 2 The top of the tank 1 is equipped with a liquid feeding box 13. The front of the liquid feeding box 13 is equipped with scale lines to facilitate quantitative dispensing of liquid medicine and improve the accuracy of medicine ratio. The surface of the solid feeding box 2 is fixedly connected to a support plate 12. The top of the support plate 12 is fixedly connected to the bottom of the liquid feeding box 13. The bottom of the liquid feeding box 13 is fixedly connected to a connecting pipe 14. The surface of the connecting pipe 14 is equipped with a solenoid valve 15. The end of the connecting pipe 14 away from the liquid feeding box 13 is fixedly connected to an annular pipe 16. The bottom of the annular pipe 16 is fixedly connected to a liquid outlet pipe 17. The liquid outlet pipes 17 are evenly distributed at the bottom of the annular pipe 16 to ensure that the liquid medicine is evenly diffused in the tank 1 and to avoid local concentrations that are too high or too low.

[0034] Reference Figure 1 , Figure 2 A stirring blade 18 is fixedly connected to the bottom of the rotating shaft 4. When the stirring blade 18 rotates, it fully mixes the solid and liquid agents to ensure the uniformity of the agent mixture. A conveying mechanism is provided on the right side of the tank body 1. The conveying mechanism includes a conveying pipe 19. A flange is provided on the right side of the conveying pipe 19 for connecting the conveying pipe 19 to the external domestic sewage treatment tank. The conveying pipe 19 is fixedly connected to the right side of the tank body 1. A solenoid valve 20 is provided on the surface of the conveying pipe 19. A flow meter 21 is fixedly connected to the top of the conveying pipe 19.

[0035] Reference Figure 1 , Figure 2 The drive mechanism includes a stepper motor 3, which is fixedly connected to the top of the solid feeding box 2. The stepper motor 3 can precisely control the rotation angle of its output shaft, making it convenient to adjust the rotation speed and rotation angle of its rotating shaft, thereby improving the control accuracy. The bottom of the output shaft of the stepper motor 3 is fixedly connected to the top of the rotating shaft 4.

[0036] Working Principle: During use, the proportion of different agent types is determined according to the sewage flow rate. Solid powder agents are added through the top feeding port of the front feeding box 11 of the solid feeding box 2. The solid powder agents fall into the gap between the turntable 5 and the fixed plate 6 by gravity through the through hole 9. The stepper motor 3 drives the rotating shaft 4 to rotate, and the turntable 5 rotates accordingly. When the turntable 5 rotates relative to the fixed plate 6, the extrusion surface 10 at the bottom of the turntable 5 and the extrusion surface 10 at the top of the fixed plate 6 rub against each other, extruding the solid powder agents between the bottom of the turntable 5 and the top of the fixed plate 6, causing the clumps of solid to be dispersed and then fall into the interior of the tank 1. Compared with the method of directly mixing solid powder agents and liquid agents, this can alleviate the problem of slow dissolution rate of solid powder agents and liquid agents due to clumping caused by long-term storage. This ensures that the agent concentration in the sewage treatment tank is consistent, thereby improving the sewage treatment effect after agent addition.

[0037] Different types of liquid agents, such as acid-base regulators and coagulants, are added to different liquid feeding tanks 13. By opening solenoid valve 15, the liquid agent enters the annular pipe 16 from the connecting pipe 14 and is then evenly sprayed into the tank 1 through the outlet pipe 17. The stepper motor 3 also drives the stirring blades 18 at the bottom of the rotating shaft 4 to rotate, so that the solid and liquid agents are evenly mixed. After the agent is mixed and treated, solenoid valve 20 is opened, and the agent is discharged through the conveying pipe 19 to the external sewage treatment tank connected to the conveying pipe 19. The opening time of solenoid valve 20 is controlled by flow meter 21, which can accurately detect and control the amount of agent added to the domestic sewage treatment tank, thus improving the control accuracy.
