[0002] The dosing device of the sewage system usually adds oxidants, reductants, flocculants, coagulants, pH regulators, etc.

[0003] The dosing pipeline of the dosing device is relatively simple. The drug outlet pipeline can be directly connected to the reaction tank that needs to be dosing in one direction. When installing the dosing pipeline, the plastic pipeline is relatively soft, and the support frame or pipe clamp needs to be denser to prevent sagging. When installing outdoors, you should also consider spraying thermal insulation or UV protection coating to extend the service life of the pipeline.

[0004] The existing dosing device requires manual mixing of medicine and water, which has low dosing efficiency and high labor intensity for workers. It is impossible to add medicine quantitatively according to needs, which easily leads to waste of resources. In addition, manual handling of medicines poses a great threat to the health of operators.

[0005] For this reason, we propose an automatic dosing device to solve the existing problems. Utility Model Content

The slide cylinder 9 is inlaid and installed on the tank body 2. A suction tube 14 is installed at the bottom opening of the slide cylinder 9. The suction tube 14 is inside the tank body 2. A discharge pipe 10 is installed at the lower opening of the slide cylinder 9. A one-way valve 13 is installed in the discharge pipe 10 and the suction tube 14. The piston rod 8 is installed inside the slide cylinder 9 for lifting and sliding.

[0029] Based on Example 1: During use, the automatic dosing device of the utility model can store the liquid medicine to be added inside the tank body 2. At this time, ensure that the piston rod 8 is at the lowest end of the slide cylinder 9. When quantitative dosing is performed, connect the external power supply to make the motor 6 work to drive the gear 5 to rotate, and through the meshing action between the gear 5 and the rack 12, drive the piston rod 8 to move upward in the slide cylinder 9. Under the action of air pressure, the liquid medicine inside the tank body 2 is sucked into the slide cylinder 9 through the suction tube 14. The amount of liquid medicine sucked in can be controlled by controlling the movement stroke of the piston rod 8. Then, the piston rod 8 can be controlled to move downward, so that the liquid medicine inside the slide cylinder 9 is squeezed out through the discharge pipe 10, and the automatic quantitative dosing operation of the liquid medicine can be completed.
