The top of the stable bracket 1 is fixedly connected with a mounting bracket 2, and a driving mechanism is arranged on the top of the mounting bracket 2. The driving mechanism includes a stepper motor 3. The stepper motor 3 can accurately control the rotation angle of its output shaft, and it is convenient to adjust the rotation speed and rotation angle of its rotating shaft. It can be adjusted accordingly according to different work requirements to improve the control accuracy. The stepper motor 3 is fixedly installed on the top of the mounting bracket 2.

The top of the stable bracket 1 is fixedly connected with a tank body 19.

[0031] Reference Figure 2-Figure 3The driving mechanism also includes a rotating shaft 4 arranged in a horizontal state, which is fixedly mounted on the front side of the output shaft of the stepping motor 3. A circular plate 5 with a circular cross-section is fixedly connected to the front side of the rotating shaft 4. The driving mechanism also includes a shaft block 7, and a threaded rod 8 is fixedly connected to the rear side of the shaft block 7. A threaded hole 6 is provided on the front side of the circular plate 5. The threaded rod 8 is threadedly mounted on the inner wall of the threaded hole 6. The shaft block 7 can be detachably mounted on the front side of the circular plate 5. The driving mechanism also includes a connecting rod 9, one end of the connecting rod 9 is hinged to the circumferential surface of the shaft block 7, and the other end of the connecting rod 9 is hinged to a vertical rod 10 arranged in a vertical state. The number of threaded holes 6 is set to multiple, and the multiple threaded holes 6 are arranged on the surface of the circular plate 5 in a straight line with equal intervals. By installing the threaded rod 8 in different threaded holes 6, the distance between the shaft block 7 and the center of the circular plate 5 can be changed.

[0032] Reference Figure 1 , Figure 3 , Figure 4 The adding mechanism includes a piston plate 11, the piston of the piston plate 11 is installed on the inner wall of the canning cylinder 13, the displacement direction of the piston plate 11 is up and down movement, the adding mechanism also includes a liquid storage tank 14 filled with chemical raw materials, the liquid storage tank 14 is fixedly installed on the top of the stable bracket 1, the left side of the liquid storage tank 14 is fixedly connected to the canning cylinder 13 through a liquid inlet pipe 15, and a one-way valve 16 is provided on the surface of the liquid inlet pipe 15. By providing the one-way valve 16, the chemical raw materials can only flow from the liquid storage tank 14 to the inside of the canning cylinder 13. The adding mechanism also includes a delivery pipe 17, and the canning cylinder 13 is delivered through the delivery pipe 17 is fixedly connected to the tank body 19, and a one-way valve 18 is arranged on the surface of the delivery pipe 17. By arranging the one-way valve 18, the chemical raw materials can only flow from the canning cylinder 13 to the inside of the tank body 19, and a pressure relief valve 20 is arranged on the surface of the delivery pipe 17 on the left side of the one-way valve 18. By arranging the pressure relief valve 20, the chemical raw materials inside the canning cylinder 13 will enter the inside of the tank body 19 only after being squeezed by the piston plate 11, thereby preventing the chemical raw materials from flowing into the inside of the tank body 19 when the piston plate 11 stops moving, thereby further improving the control accuracy of the addition amount of the chemical raw materials.

[0033] Working principle: When in use, the power supply of the stepper motor 3 is started, the stepper motor 3 works to drive the rotating shaft 4 to rotate, the rotation of the rotating shaft 4 drives the circular plate 5 to rotate, the rotation of the circular plate 5 drives the connecting rod 9 to move, the movement of the connecting rod 9 squeezes or pulls the vertical rod 10, and then the vertical rod 10 makes a linear reciprocating motion in the vertical direction on the inner wall of the canning cylinder 13, the movement of the vertical rod 10 drives the piston plate 11 to make a linear reciprocating motion, the movement of the piston plate 11 cooperates with the one-way valve 16 and the one-way valve 2 18 and the pressure relief valve 20 to press the chemical raw materials inside the liquid storage tank 14 into the inside of the tank body 19. When the chemical raw materials are pressed into the tank body When the chemical raw materials inside 19 reach the required amount, the stepper motor 3 stops working. Since the rotation angle of the stepper motor 3 and the volume inside the canning cylinder 13 are controllable, the chemical raw materials pressed into the tank body 19 can be accurately controlled, thereby accurately controlling the amount of added chemicals, and the chemical raw materials inside the canning cylinder 13 are blocked by the pressure relief valve 20 to prevent the chemical raw materials from entering the tank body 19 under the action of gravity, resulting in inaccurate amount of chemical added inside the tank body 19, further improving the control accuracy of the amount of chemical added.

[0034] By loosening the threaded rod 8, the shaft block 7 is removed from the surface of the circular plate 5, and then the position of the threaded rod 8 in the threaded hole 6 is replaced appropriately according to the needs of different chemicals. Then, the threaded rod 8 is tightened and the shaft block 7 is re-fixed on the front side of the circular plate 5. The speed of injecting chemical raw materials into the tank body 19 can be controlled, thereby accurately controlling the amount of chemicals added.
