[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Combined with appendix Figure 1-3 An environmentally friendly sodium hexametaphosphate water treatment water circulation device includes a sodium hexametaphosphate supply system. The sodium hexametaphosphate supply system includes a premixing tank 1 and a postmixing tank 2. The postmixing tank 2 is equipped with a circulating water supply pipe 3 and a circulating water outlet pipe 4. The circulating water to be treated is input through the circulating water supply pipe 3 and output through the circulating water outlet pipe 4.

[0018] The premixing tank 1 is equipped with a water supply valve pipe 9 and a sodium hexametaphosphate feeding valve pipe 10 at the top for convenient water and sodium hexametaphosphate addition. The valves on the water supply valve pipe 9 and the feeding valve pipe 10 are preferably quantitative valves to control the addition amount. A first stirring motor 11 is located at the top of the premixing tank 1, and a first stirrer 12 extending into the premixing tank 1 is located at the power end of the first stirring motor 11. Multiple resistance heating rods 13 are located inside the premixing tank 1. A temperature sensor 14 and a concentration sensor 15 are located at the bottom of the premixing tank 1. When mixing sodium hexametaphosphate liquid is required, water and sodium are added through the water supply valve pipe 9 and the feeding valve pipe 10. Distilled water is preferred to ensure purity and the accuracy of the concentration sensor 15. Temperature is controlled by the resistance heating rods 13 and the temperature sensor 14. The first stirring motor 11 drives the first stirrer 12 to rotate and mix, ensuring rapid mixing of the sodium hexametaphosphate.

[0019] The premixing tank 1 is provided with a liquid guide pipe 5 at the bottom, and a temporary storage tank 6 is provided at the end of the liquid guide pipe 5. A liquid pump 7 is provided on one side of the bottom of the temporary storage tank 6. The liquid pump 7 is provided with a liquid delivery pipe 8 that is connected to the postmixing tank 2. Because the circulating water is continuously treated, the liquid supply cannot be stopped when water and sodium hexametaphosphate are mixed in the premixing tank 1. Therefore, the temporary storage tank 6 is set up so that the sodium hexametaphosphate mixture can be continuously supplied to the postmixing tank 2 while water and sodium hexametaphosphate are mixed in the premixing tank 1.

[0020] The liquid guide pipe 5 is equipped with an electrically controlled valve 23 at one end near the premixing tank 1. The liquid delivery pipe 8 is equipped with a first check valve 16 and a first flow control valve 17. The circulating water supply pipe 3 is equipped with a second check valve 18 and a second flow control valve 19. The check valve can prevent liquid backflow, and the flow control valve can adjust the delivery volume of sodium hexametaphosphate mixture according to the delivery volume of the circulating water supply pipe 3, thereby ensuring precise control of the amount of sodium hexametaphosphate added.

[0021] The top of the post-mixing tank 2 is equipped with a second stirring motor 20, and the bottom power end of the second stirring motor 20 is equipped with a second agitator 21 extending into the post-mixing tank 2. The top of the post-mixing tank 2 is equipped with a sealed bearing 22 that cooperates with the second agitator 21. By setting the second stirring motor 20 and the second agitator 21 together, the water to be treated and the sodium hexametaphosphate mixture can be quickly and efficiently mixed the moment they enter the post-mixing tank 2. The mixed liquid is discharged through the circulating water outlet pipe 4 for subsequent water treatment operations.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
