[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figure 1 - Figure 2 , an embodiment provided by the present utility model: A circulating water dosing device for a refrigeration system, including a base 1, four metering pumps 8 are fixedly connected to the top of the base 1, two medicine tanks 9 are fixedly connected to the top of the base 1, a medicine delivery pipe 7 is fixedly connected to the side wall of the medicine tank 9, the inside of the medicine delivery pipe 7 is fixedly connected to the input end of the metering pump 8, the output end of the metering pump 8 is fixedly connected to a main water pipe 6, a water sample detector 5 is fixedly connected to the top of the main water pipe 6, a control box 2 is arranged above the water sample detector 5, a pipeline is connected between the bottom of the control box 2 and the top of the water sample detector 5, a flow detector 3 is arranged on the right side of the control box 2, a pipeline is connected between the flow detector 3 and the water sample detector 5, a coupon unit 10 is arranged on the left side of the control box 2, a sampling valve 4 is fixedly connected to the bottom of the coupon unit 10, a rotating assembly is arranged on the top of the medicine tank 9, and the rotating assembly is used for stirring the inside of the medicine tank 9. The two medicine tanks 9 are located on both sides of the metering pump 8. The coupon unit 10 can detect the wear condition of the coupon. The metering pump 8 and the control box 2 are electrically connected, and the water sample detector 5 and the control box 2 are electrically connected.

[0030] Specifically, in this embodiment, the water sample detector 5 can be used to monitor the water quality in the circulating water in real time, and parameters such as water quality PH, concentration multiple, conductivity, turbidity, ORP, etc. can be obtained and transmitted to the control box 2 for analysis and processing. The flow detector 3 can analyze the water flow in the water pipe, obtain the water flow signal, and assist the control unit to make control instructions. The coupon unit 10 can monitor the corrosion condition of the coupon in real time, and the sampling valve 4 can be used to take real-time samples of the water quality at any time. The control box 2 analyzes the obtained sample data to obtain the required chemical content, and sends a control command to the metering pump 8 through a 4-20 mA signal. After receiving the command, the metering pump 8 starts to pump the liquid medicine in the chemical tank 9 into the main water pipe 6 through the medicine delivery pipe 7, completing the treatment of the circulating water, without redundant manual operations, saving a large amount of manpower, saving the dosage of chemicals, and making the chemical addition amount more accurate.

[0031] Referring to Figure 3 , the rotating assembly includes a bracket 13, the bottom of the bracket 13 is fixedly connected to the top of the chemical tank 9, the top of the bracket 13 is fixedly connected with a motor 12, the output end of the motor 12 is fixedly connected with a main gear 14, the top of the main gear 14 is fixedly connected with a plurality of clamping blocks 17, the inside of the chemical tank 9 is rotatably connected with a stirring rod 15, the top of the stirring rod 15 is fixedly connected with a driven gear 16, and the driven gear 16 meshes with the clamping blocks 17. A medicine inlet 11 is formed in the side wall of the chemical tank 9, and two main gears 14 are rotatably connected to the top of the chemical tank 9, and the two main gears 14 mesh with each other.

[0032] Specifically, in order to make the drug and water mix faster, a stirring rod 15 is provided inside the chemical tank 9. After the drug is added through the medicine inlet 11, only the motor 12 needs to be started, and the main gear 14 rotates. Since the two main gears 14 mesh with each other, the two main gears 14 start to rotate in opposite directions. Since a plurality of clamping blocks 17 are provided at the top of the main gear 14, and the driven gear 16 meshes with the clamping blocks 17, when the clamping blocks 17 rotate with the main gear 14, the driven gear 16 will be driven to rotate. Specifically, the number of clamping blocks 17 on the top of one main gear 14 is half of the number of teeth on the outside of the driven gear 16. Therefore, the driven gear 16 can first mesh with the clamping blocks 17 on one main gear 14, and at this time, it can rotate half a turn, and then mesh with the clamping blocks 17 on the top of the other main gear 14, and the driven gear 16 will rotate half a turn in the opposite direction. The stirring rod 15 is driven by the driven gear 16 to rotate reciprocally inside the chemical tank 9, accelerating the mixing speed of the drug and water.

[0033] Working principle: The intelligent operation of the device can be realized through the set control box 2. The water sample detector 5 can accurately monitor parameters such as the water quality PH, concentration multiple, conductivity, turbidity, and ORP of the system, and upload them to the control box 2 for analysis and processing. The flow detector 3 can analyze the water flow signal. After the control box 2 collects this information, it sends control commands to the metering pump 8 through a 4-20 mA signal. The metering pump 8 can control the dosage of the medicine pumped into the circulating water to achieve the best cleaning effect on the circulating water without causing unnecessary waste of medicine. The required medicine powder can be added to the medicine tank 9. After starting the motor 12, it drives the main gear 14, and uses the clamping blocks 17 at the top of the two main gears 14 to drive the driven gear 16 to rotate reciprocally in the opposite direction. The stirring rod 15 can fully mix the medicine powder and water inside the medicine tank 9, eliminating the need for redundant manual operations, saving a large amount of manpower, and having a more obvious cleaning effect on the circulating water.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
