[0026] As a technical optimization solution of the present invention, refer to Figure 1 and Figure 2 As shown, a mounting bracket 6 is fixedly installed on the top of the adding and mixing barrel 1, and a servo motor 7 is fixedly installed on the bottom of the mounting bracket 6. The output end of the servo motor 7 is connected to a rotating shaft 8. One end of the rotating shaft 8 extends into the adding and mixing barrel 1 and is installed with a stirring assembly. The stirring assembly includes a plurality of stirring rods 9 fixedly installed on the rotating shaft 8. The plurality of stirring rods 9 are located in the adding and mixing barrel 1. The operation of the servo motor 7 drives the rotating shaft 8 to rotate, thereby driving the plurality of stirring rods 9 to rotate, and can stir the sewage transported in.

[0027] As a technical optimization solution of the present invention, refer to Figure 2 , Figure 4 and Figure 5 As shown, an addition barrel 10 is arranged above the addition mixing barrel 1, a restraint belt 11 is arranged between the mounting bracket 6 and the addition barrel 10, an addition port is arranged above the addition barrel 10, a control tube 12 is connected to the bottom of the addition barrel 10, a quantitative addition component is arranged in the control tube 12, the quantitative addition component is connected to the rotating shaft 8, the bottom of the control tube 12 is connected to an annular tube 15 through a connecting component, a drip head 16 is arranged at the bottom of the annular tube 15, and the quantitative addition component includes a baffle plate 25 fixedly installed inside the control tube 12, and a lower The top of the blocking plate 25 is provided with a sealing plate 27, which blocks the upper position of the blocking plate 25. A push rod 28 is fixedly installed on one side of the sealing plate 27, and an arc-shaped push block 29 is fixedly installed on one end of the push rod 28. An elliptical extrusion block 30 is fixedly sleeved on the rotating shaft 8, and the elliptical extrusion block 30 is adapted to the arc-shaped push block 29. An extrusion spring 31 is fixedly installed between the arc-shaped push block 29 and the control tube 12. A large amount of residual chlorine solution is stored in the adding barrel 10, and the residual chlorine solution is a sodium hypochlorite solution. The solution enters the control tube 12. The sealing plate 27 blocks the drop hole 26. At this time, the residual chlorine solution cannot fall. As the rotating shaft 8 rotates, the elliptical extrusion block 30 on the quantitative addition component will be driven to rotate. After the elliptical extrusion block 30 rotates, it will contact and squeeze the arc-shaped push block 29. The arc-shaped push block 29 moves after being squeezed, driving the push rod 28 to move. At this time, the sealing plate 27 will move to one side. At this time, the drop hole 26 will be opened, and the residual chlorine solution will fall from the drop hole 26, enter the annular tube 15 along the circulation pipe 13 and the telescopic pipe 14, and finally drip from the drip head 16. The annular tube 15 is arranged in an annular structure, and the dripping head 16 can evenly drip the residual chlorine solution to the bottom.

[0028] As a technical optimization solution of the present invention, refer to Figure 2 , Figure 3 and Figure 5As shown, an annular plate 18 is connected to the top of the annular tube 15, a telescopic adjustment component is connected between the top of the annular plate 18 and the top inner wall of the adding mixing barrel 1, an extrusion and shaking component is arranged between the annular plate 18 and the rotating shaft 8, the connecting component includes a flow tube 13 fixedly connected to the bottom of the control tube 12, the bottom end of the flow tube 13 is connected to the telescopic tube 14, the telescopic tube 14 is connected to the annular tube 15, the extrusion and shaking component includes a driving rod 22 fixedly mounted on the rotating shaft 8, the end of the driving rod 22 is rotatably mounted with a moving roller 23, and the moving roller 23 is arranged to move the moving roller 23. The roller 23 is located below the annular plate 18. A plurality of arc-shaped adjustment blocks 24 are fixedly installed at the bottom of the annular plate 18. The plurality of arc-shaped adjustment blocks 24 are adapted to the movable roller 23. The telescopic adjustment assembly includes a movable sleeve 19 fixedly installed on the inner wall of the top side of the adding mixing barrel 1. A movable rod 20 is fixedly installed on the top of the annular plate 18. The top of the movable rod 20 extends into the movable sleeve 19. A return spring 21 is fixedly installed between the top of the movable rod 20 and the inner wall of the movable sleeve 19. The annular tube 15 is connected to the outer side of the annular plate 18 by a connecting frame. 17, an extrusion and shaking-off assembly is provided, and the driving rod 22 on the extrusion and shaking-off assembly moves with the rotation of the rotating shaft 8, and the driving rod 22 can drive the moving roller 23 to move. After the moving roller 23 rotates, it will contact and squeeze the arc-shaped adjustment block 24. After the arc-shaped adjustment block 24 moves up, it drives the annular plate 18 to move up, and at this time drives the moving rod 20 to move and compress the reset spring 21. Under the driving action of the connection of the connecting frame 17, the annular tube 15 also moves up. When the moving roller 23 is misaligned with the arc-shaped adjustment block 24, one side of the arc-shaped adjustment block 24 is a cliff. The mode is interrupted, and the mobile roller 23 is acted upon by the elastic force of the reset spring 21, which drives the annular plate 18 to move downward, thereby achieving a vibration effect. The residual chlorine solution in the annular tube 15 can fully fall, thereby avoiding the problem that the residual chlorine solution cannot effectively drip. The dripping residual chlorine solution can be fully mixed with the internal sewage as the stirring rod 9 continues to rotate, thereby achieving a sterilization effect. Through the setting of this scheme, sewage can be continuously transported for sterilization, and the only requirement is to ensure the amount of residual chlorine solution in the adding barrel 10, thereby effectively solving the problem of traditional manual addition of residual chlorine.

[0029] During use: During the sewage treatment process, the servo motor 7 drives the rotating shaft 8 to rotate, thereby driving the multiple stirring rods 9 to rotate, and the sewage transported in can be stirred. The quantitative addition component is set, the rotating shaft 8 rotates to drive the elliptical extrusion block 30 to rotate, and the arc-shaped push block 29 drives the push rod 28 to move after being squeezed. At this time, the sealing plate 27 will move to one side, and the drop hole 26 will be opened. The residual chlorine solution will fall from the drop hole 26, and the solution will drip from the drip head 16, which can evenly drip the residual chlorine solution to the bottom through slow rotation and stirring, so as to achieve quantitative addition of residual chlorine solution, avoid excessive addition at one time, resulting in insufficient reaction between sewage and residual chlorine solution, and the sterilization and disinfection effect. In order to solve the problem of poor quality, an extrusion and shaking-off component is set up. The driving rod 22 on the extrusion and shaking-off component drives the moving roller 23 to move, contact and extrude the arc-shaped adjusting block 24, and drive the annular plate 18 to move up. With continuous rotation and under the action of the reset spring 21, the annular plate 18 is driven to move down to achieve the vibration effect. The residual chlorine solution in the annular tube 15 can fully fall, avoiding the problem that the residual chlorine solution cannot effectively drip. The dripping residual chlorine solution can be fully mixed with the internal sewage as the stirring rod 9 rotates continuously to achieve the sterilization effect. Through the setting of this scheme, the sewage can be continuously transported and sterilized. As long as the amount of residual chlorine solution in the adding barrel 10 is guaranteed, the problem of traditional manual addition of residual chlorine is effectively solved.
