[0022] Please see Figure 1-4 An automatic dosing device for a wastewater treatment facility includes a treatment cylinder 1, with a dosing mechanism 2 disposed above the treatment cylinder 1.

[0023] The dosing mechanism 2 includes a fixed frame 201, the outer surface of which is fixedly connected to the outer surface of the processing cylinder 1. A first servo motor 202 is fixedly connected to the upper surface of the fixed frame 201. Three support legs 3 are fixedly connected to the bottom surface of the processing cylinder 1. A base 4 is fixedly connected to the bottom surface of each support leg 3. The support legs 3 are connected to the bottom surface of the processing cylinder 1 to provide vertical support force for the processing cylinder 1, so that the processing cylinder 1 can be placed stably. The base 4 is connected to the bottom surface of the support legs 3, which increases the contact area with the ground. According to the principle of physics, under a certain pressure, the larger the contact area, the smaller the pressure. This makes the entire device more stable on the ground, reducing the impact on the internal structure of the device that may be caused by shaking, and ensuring that the automatic dosing device can operate normally.

[0024] The output end of the first servo motor 202 passes through the fixed frame 201 and is fixedly mounted with a gear 203. The outer surface of the gear 203 is meshed with a rotating gear disk 204. A protective cover 5 is fixedly connected to the outer surface of the first servo motor 202. The bottom surface of the protective cover 5 is fixedly connected to the upper surface of the fixed frame 201. The protective cover 5 can protect the first servo motor 202 and prevent foreign objects from hitting the motor. The protective cover 5 can extend the service life of the first servo motor 202 and reduce motor failures caused by external environmental factors, thereby ensuring the normal operation of the dosing mechanism 2.

[0025] The outer surface of the rotating gear disk 204 is rotatably connected to the inner wall of the fixed frame 201. Three limiting rings 205 are fixedly connected to the bottom surface of the rotating gear disk 204. Two reinforcing blocks 13 are fixedly connected to the bottom surface of the fixed frame 201. The outer surface of each reinforcing block 13 is fixedly connected to the outer surface of the treatment cylinder 1. The reinforcing blocks 13 are connected to the bottom surface of the fixed frame 201 and the outer surface of the treatment cylinder 1, which enhances the connection strength between the fixed frame 201 and the treatment cylinder 1 from the side. During the operation of the device, especially when the dosing mechanism 2 is used for dosing, a certain vibration or torque may be generated. The reinforcing blocks 13 can prevent the connection between the fixed frame 201 and the treatment cylinder 1 from loosening, and ensure the integrity and stability of the entire device structure.

[0026] Three drug storage cylinders 206 are arranged below the rotating toothed disc 204. The outer surface of each drug storage cylinder 206 is in contact with the inner wall of the limiting ring 205. A controller 6 is fixedly connected to the front of the fixed frame 201, and a second servo motor 8 is fixedly connected to the inner top wall of the fixed frame 201. The controller 6 can conveniently control the drug addition and stirring work, as well as the drug addition flow rate. The controller 6 can operate the drug addition work according to the preset program. The controller 6 is the core component of the whole system. It receives signals from the equipment and processes them according to the preset algorithm and logic. The controller 6 usually uses a microprocessor or microcontroller chip to realize its functions. The second servo motor 8 can provide power for drug addition and stirring, so that the mixing and stirring work can be carried out quickly.

[0027] Each limiting ring 205 has a screw 207 threadedly connected to its inner wall. Each screw 207 has a compression ring 208 rotatably connected to one end near the limiting ring 205. The output end of the second servo motor 8 is fixedly connected to a stirring shaft 7. The bottom end of the stirring shaft 7 is rotatably connected to the inner wall of the treatment cylinder 1. When the second servo motor 8 is started, the stirring shaft 7 starts to rotate and stirs the sewage inside the treatment cylinder 1. During the dosing process, the agent enters the treatment cylinder 1 from the dosing mechanism 2. The rotation of the stirring shaft 7 can break the stratification between the sewage and the agent, so that the agent can spread quickly and evenly in the sewage.

[0028] The outer surface of each extrusion ring 208 is slidably connected to the inner wall of the limiting ring 205, and the outer surface of each extrusion ring 208 is in contact with the outer surface of the storage cylinder 206. A flow meter 11 is fixedly connected to the outer surface of each storage cylinder 206, and a solenoid valve 12 is fixedly connected to the outer surface of each storage cylinder 206. A sealing cover 9 is slidably connected to the inner wall of each storage cylinder 206, and a pull block 10 is fixedly connected to the upper surface of each sealing cover 9. The flow meter 11 can monitor the flow rate of the agent flowing out of the storage cylinder 206 in real time. In the wastewater treatment process, different wastewater qualities and treatment stages require different dosages of chemicals. The flow data monitored by the flow meter 11 is fed back to the controller 6. The controller 6 can control the opening and closing degree of the solenoid valve 12 according to the preset dosing scheme, thereby achieving precise dosing. Precise control of the dosage of chemicals added from the storage tank 206 to the treatment tank 1 avoids waste and ensures effective wastewater treatment. Appropriate dosage is crucial for the proper chemical reaction in wastewater treatment. Both the flow meter 11 and the solenoid valve 12 are equipped with WiFi modules for wireless control, eliminating the need for wiring. The sealing cover 9 effectively prevents the chemicals in the storage tank 206 from evaporating or becoming contaminated. When chemicals need to be replaced or replenished, operators can easily open the sealing cover 9 using the pull block 10. This structure ensures the quality of chemical storage, facilitates chemical management, and improves the practicality and maintainability of the entire automatic dosing device.

[0029] The working principle of this utility model is as follows: During use, the operator connects the electrical equipment to the power supply and electrically connects the first servo motor 202 and the second servo motor 8 to the controller 6. Simultaneously, the connection configuration between the flow meter 11 and the solenoid valve 12 and the controller 6 is completed. The automatic dosing device of the sewage treatment facility begins operation. A dosing mechanism 2 is located above the treatment cylinder 1. When dosing is required, the operator sets the dosing amount through the controller 6. Then, the controller 6 controls the activation of the first servo motor 202, the second servo motor 8, the flow meter 11, and the solenoid valve 12. The first servo motor 202 starts, driving the gear 203 to rotate. The gear 203 meshes with the rotating gear disk 204, causing the rotating gear disk 204 to rotate. The bottom surface of the rotating gear disk 204 has three limiting rings 205. The device corresponds to three drug storage cylinders 206, which can drive the drug storage cylinders 206 to rotate and add drugs. Each drug storage cylinder 206 has related components to assist in drug addition. There is a flow meter 11 and a solenoid valve 12 on the outside of the drug storage cylinder 206. The flow meter 11 can monitor the drug addition flow rate, and the solenoid valve 12 controls the on and off of the drug addition. There is a sealing cover 9 inside the drug storage cylinder 206. The sealing cover 9 has a pull block 10 for easy operation. The second servo motor 8 on the top wall of the fixed frame 201 is started, which drives the stirring shaft 7 to rotate inside the treatment cylinder 1. This helps the drugs to be fully mixed with the sewage in the treatment cylinder 1. When the flow meter 11 detects that the specified flow rate has been reached, the controller 6 controls the shutdown of the equipment, thereby realizing automatic and uniform drug addition. Finally, the treated sewage is discharged through the drain pipe at the bottom of the treatment cylinder 1.
