[0022] As Figures 1-6 shown, an automatic chemical addition device includes a sewage tank 1, a liquid storage barrel 2, a sprayer 3 and a piston 4. A sewage inlet pipe 5 is provided on the left side plate of the sewage tank 1, and a sewage discharge pipe 6 is provided on the right side plate of the sewage tank 1. The height of the sewage discharge pipe 6 is less than that of the sewage inlet pipe 5. The liquid storage barrel 2 is fixedly connected to the top of the sewage tank 1. A chemical addition pipe 7 is provided on the left side of the top of the liquid storage barrel 2. The bottom of the liquid storage barrel 2 is fixedly connected with a liquid outlet pipe 8. A motor 9 is fixedly connected to the center of the top of the liquid storage barrel 2. The bottom end of the motor 9 is connected with an output shaft 10. The output shaft 10 is rotatably connected to the liquid storage barrel 1. The bottom end of the output shaft 10 is fixedly connected with a reciprocating screw 11. A piston 4 is engaged with the reciprocating screw 11. The piston 4 is hermetically and slidably connected in the liquid outlet pipe 8. The bottom of the reciprocating screw 11 is fixedly connected with a sealing disc 12. The sealing disc 12 is rotatably connected in the liquid outlet pipe 8. A guide rod 13 is fixedly connected in the liquid outlet pipe 8. The guide rod 13 is slidably connected with the piston 4. A protective cover 14 is sleeved and rotatably connected on the liquid outlet pipe 8. A first water outlet 15 is evenly arranged in a circle at the position corresponding to the protective cover 14 on the liquid outlet pipe 8. Horizontal pipes 16 are symmetrically fixedly connected to the protective cover 14. The other ends of the horizontal pipes 16 are fixedly connected with installation barrels 17. A vertical pipe 18 is rotatably connected to the installation barrel 17. A water inlet 19 is provided at the position of the vertical pipe 18 corresponding to the installation barrel 17. The bottom end of the vertical pipe 18 is fixedly connected with the sprayer 3. The second water outlets 20 are densely arranged on the sprayer 3.

[0023] Furthermore, a groove 21 is provided on the inner bottom wall of the liquid outlet pipe 2. The groove 21 matches the sealing disc 12. A connecting rod 22 is fixedly connected to the lower surface of the sealing disc 12. The sealing disc 12 and the protective cover 14 are fixedly connected through the connecting rod 22.

[0024] Furthermore, a tooth ring 23 is fixedly connected to the inner top surface of the sewage tank 1. The top of the vertical pipe 18 is fixedly connected with a gear 24 through a shaft rod 25. The gear 24 is engaged with the inner ring of the tooth ring 23.

[0025] Further, stirring blades 26 are provided on the vertical pipe 18.

[0026] Further, a reciprocating thread sleeve 27 is fixedly connected inside the piston 4, and the reciprocating screw rod 11 is engaged in the reciprocating thread sleeve 27.

[0027] A specific embodiment of the present utility model is as follows:

[0028] As Figure 1 and 2 shown, the liquid storage barrel 2 is fixedly connected to the top of the sewage tank 1, and the toothed ring 23 is fixedly connected to the top inner wall of the sewage tank 1. The gear 24 is engaged with the toothed ring 23. The motor 9 is fixedly connected to the upper surface of the liquid storage barrel 2. The liquid outlet pipe 8 is fixedly connected to the bottom of the liquid storage barrel 2. The bottom of the liquid outlet pipe 8 is sealed by the sealing disc 12. The protective cover 14 is fixedly connected to the sealing disc 12 through the connecting rod 22. The protective cover 14 is sleeved and rotatably connected on the liquid outlet pipe 8.

[0029] When sewage flows into the sewage tank from the sewage inlet pipe 5, the motor 9 starts to work, drives the screw rod 11 to rotate through the output shaft 10, the piston 4 makes a reciprocating motion on the screw rod 11, squeezes the liquid medicine to flow into the protective cover 14 from the first liquid outlet 15, flows into the installation barrel 17 through the horizontal pipe 16, enters the vertical pipe 17 from the water inlet 19, sprays the liquid medicine through the second liquid outlet 20, and at the same time the stirring blades 26 perform stirring. When the sewage liquid level gradually rises, the sewage is discharged from the sewage discharge pipe 6, so as to uniformly stir the sewage and purify the sewage.

[0030] When the motor 9 works, it drives the screw rod 11 to rotate. The piston 4 is hermetically and slidably connected in the liquid outlet pipe. Since the piston 4 is engaged with the screw rod 11 through the reciprocating thread sleeve 27 and the piston 4 is guided by the guide rod 13, when the screw rod 11 rotates, the piston 4 makes a vertical reciprocating movement. When the piston 4 moves to the highest point, the liquid medicine flows into the liquid outlet pipe 8. When the piston 4 gradually moves to the lowest point, the piston 4 squeezes the liquid medicine to flow out from the first liquid outlet 15. At the same time, the screw rod 11 drives the sealing disc 12 to rotate, and the connecting rod 22 connected to the sealing disc 12 drives the installation barrel 17 to rotate along the outer wall of the liquid outlet pipe 8, drives the horizontal pipe 16 and the installation barrel 17 to rotate. At the same time, the gear 24 moves around the toothed ring 23, drives the vertical pipe 18 to rotate in the installation barrel 17 through the shaft rod 25, so as to realize that while the stirring blades 26 and the spray head 3 revolve around the screw rod 11, they also rotate by themselves through the gear 24. After the sewage treatment is completed, the motor 9 stops working, the piston 4 reaches the bottom of the liquid outlet pipe 8, the piston seals the liquid medicine in the liquid storage barrel 2, and the liquid medicine no longer discharges. At the same time, the sealing disc 12 can ensure the sealing performance of the liquid outlet pipe 8.
