[0032] The automatic dosing device for sewage treatment is designed to accurately add chemicals and optimize sewage treatment. The device includes a machine 1, the top of which is equipped with a base 4, and a rotating drive member 5 is installed on the base 4. The drive member drives the screw 6 to rotate, and controls the horizontal movement of the sewage treatment barrel 10 through the nut seat 8 and the guide rod 7. The sewage treatment barrel 10 is equipped with a pH sensor 2101, a turbidity sensor 2102 and a total phosphorus sensor 2103, and a water quality monitoring box 22 is set on the top of the supporting plate 9. The surface of the water quality monitoring box 22 is provided with an analyzer in the water quality monitoring box that cooperates with the pH sensor 2101, the turbidity sensor 2102 and the total phosphorus sensor 2103 for monitoring, so as to monitor the parameters in the sewage in real time.

The PLC drives the solenoid valve 18 and the variable frequency motor 16 to ensure that the medicine can be added efficiently and accurately, and the stirring paddle 19 is used to keep the medicine evenly mixed.

[0034] To enhance the functionality, the liquid storage barrel 14 and the sewage treatment barrel 10 of the dosing device are also equipped with a liquid level meter 23 on their inner walls. The liquid level meter 23 can be used to monitor the liquid level of the agent in the liquid storage barrel 14 and the sewage treatment barrel 10. The output end of the liquid level meter 23 is electrically connected to the input end of the PLC controller inside the control panel 3, so the liquid level data monitored by the liquid level meter 23 can be displayed in real time by the control panel 3. When the liquid medicine inside the liquid storage barrel 14 and the sewage treatment barrel 10 is at a low liquid level, the staff can observe this phenomenon based on the liquid medicine level displayed on the control panel 3, so that the operator can replenish the agent in time.

The communication module 25 is a 5G communication module. The setting of the communication module 25 is easy for the device to monitor the operating status of the device and the corresponding The alarm is transmitted remotely, and the top of the sewage treatment barrel 10 is partially blocked to prevent dust, debris, and rainwater from entering the sewage treatment barrel 10. The remaining space after the sewage treatment barrel 10 is blocked is sufficient for the liquid storage barrel 14 to add medicine. An eaves board 26 is added to the top of the vertical plate 2 so that the device can be placed outdoors for use. It can also protect the control panel 3 and its PLC, and improve the use range of the device. The filling pipe 17 on the outer wall of each liquid storage barrel 14 is tilted downward by three to five degrees. After the addition is completed, the residual agent in the solenoid valve 18 can be drained to achieve the purpose of protecting the solenoid valve 18, so that the solenoid valve 18 can have a longer service life.
