[0002] With the continuous development of industrial production, the application of circulating cooling water systems is becoming more and more extensive. A circulating cooling water system refers to a cooling operation system that uses water as a cooling medium and circulates it.

[0003] Publication No.: CN114538659B, titled: A Method and System for Controlling and Treating Circulating Water Quality, includes the following steps: S1. Add an oxidizing biocide to the pump suction inlet of the circulating water tank and add it continuously for 24 hours. The oxidizing biocide used is sodium hypochlorite; S2. Regularly take samples to detect the residual chlorine content; S3. If the residual chlorine content detected in step S2 exceeds the range, change the addition concentration of sodium hypochlorite; S4. Regularly add a non-oxidizing biocide and stop adding the oxidizing biocide before adding the non-oxidizing biocide; S5. After the addition of the non-oxidizing biocide is completed, continue to add the oxidizing biocide. This application enables the control of the quality of circulating water by regularly adding oxidizing biocides and non-oxidizing biocides to the circulating water.

[0015] Preferably, a chemical dosing method for a circulating water quality automatic chemical dosing system includes the following steps:

[0016] Step 1: The acquisition module collects the water quality information in the water tank main body and feeds it back to the user control terminal. The user control terminal controls the servo motor to start. The servo motor drives the stirring rod to rotate. Through the connection of the coupling rod, the rotating table is driven to rotate. As the rotation progresses, different medicine storage tanks on the rotating table are driven to move. When the medicine storage tank moves to the material receiving assembly, the data information in the RFID identification board at the medicine storage tank is read by the RFID scanner. After confirming that it is the required medicine storage tank, the first flow control valve is opened to let the medicine in the medicine storage tank fall into the material receiving groove through the channel;

[0036] Please refer to Figure 2 , Figure 3 , Figure 4 , the docking assembly 5 includes an elbow pipe 501 installed at the discharge end of the discharge valve 406. One end of the elbow pipe 501 is installed with an assembly frame 502. Two sets of electric telescopic rods 503 are installed on the outer wall of the assembly frame 502.

A plurality of medicine adding valves 102 are installed above the water tank main body 1. A magnetic attraction ring 103 is installed in the upper slot of the medicine adding valve 102. A collection module 101 is installed on one side of the medicine adding valve 102. The detection end of the collection module 101 extends into the water tank main body 1. Two sets of infrared receivers 104 are installed around the medicine adding valve 102. The moving frame 3 includes an outer frame body 301.

Displacement sliders 204 are installed on the outer walls of the ball screw 201 and the guide rod 203.

[0037] The acquisition module 101 is used to collect the water quality changes in the water tank at its location. Specifically, this module includes multiple pH sensors, residual chlorine sensors, bacterial content sensors, etc., which are used to monitor various water quality parameters of the circulating water in real time. These sensors are distributed at different node positions in the circulating water system and can comprehensively and accurately obtain water quality data. Through the settings of the magnetic dosing valve 102 and the magnetic ring 103, they are used to control the opening and closing state here and can be magnetically connected to the docking interface 505 in a magnetic attraction manner, which is convenient for the two to be combined together and improves the sealing performance between the two. Through the setting of the docking assembly 5, the mixed medicine can be sent into the water tank to achieve the purpose of dosing. Specifically, through the setting of the electric telescopic rod 503, it can drive the telescopic tube 504 to expand and contract, so as to form a channel structure for the medicine to be fed into the inner cavity of the water tank. This structure can also facilitate the subsequent rapid separation of the docking interface 505 from the dosing valve 102 after dosing. The lead screw motor 202 and the ball screw 201 can make the displacement slider 204 perform linear displacement.

Through the connection of the coupling rod 408, it drives the rotating table 703 to rotate. As the rotation progresses, it drives the different medicine storage tanks 706 on the rotating table 703 to move. When the medicine storage tank 706 moves to the feeding assembly 6, the data information in the RFID identification board 707 of the medicine storage tank 706 is read by the RFID scanner 605. After confirming that it is the required medicine storage tank 706, the first flow control valve 603 is opened to make the medicine in the medicine storage tank 706 fall into the feeding trough 601 through the channel 702;

[0040] Step 2: The medicine in the feeding trough 601 enters the second flow control valve 705 through the material dropping port 602. The second flow control valve 705 is opened to make the medicine flow along the pipeline into the mixing tank 401. The stirring rod 404 and the stirring blade 405 in the mixing tank 401 stir and mix the medicine;

[0041] Step 3: During the mixing process, the displacement assembly 2 drives the moving frame 3 to displace to the position of the required dosing valve 102, and the required position is determined through the infrared receiver 104 and the infrared emitter 303;

[0042] Step Four: The electric telescopic rod 503 drives the docking port 505 to move downward, so as to form a communication channel among the elbow pipe 501, the telescopic pipe 504, the docking port 505 and the chemical addition valve 102. After the mixing is completed, the discharge valve 406 is opened, so that the mixed medicine enters the main body of the water tank 1 through the communication channel;

[0043] Step Five: After the chemical addition, the acquisition module 101 collects the water quality change after the chemical addition again and feeds the data back to the user control terminal. The user performs the operation of adding medicine again or ending the chemical addition according to the water quality change information at the control terminal.
