[0003] Since peracetic acid disinfectant has certain corrosivity, it must be diluted before use. According to the different disinfection targets, the concentration of disinfectant used is also different, for example, when disinfecting food, the required concentration is 0.2-0.5%; when disinfecting tableware, the required concentration is 0.5%; when disinfecting building, the required concentration is 10-15%; when hand or skin disinfection is needed, the concentration is generally not more than 0.2%.

[0004] Therefore, different concentrations of peracetic acid disinfectant need to be prepared for different needs. At present, the dilution process of peracetic acid disinfectant is mainly completed by manual, first, the worker adds a proper amount of water into the stirring tank, then slowly adds peracetic acid stock solution into the stirring tank, and stirs while adding to prevent releasing too much heat. The concentration of disinfectant needs to be tested repeatedly during the dilution process to see if it meets the standard, if not, water or stock solution needs to be added again until the concentration meets the standard. Therefore, this dilution method is low in efficiency and needs to be improved. UTILITY MODEL CONTENTS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] like Figs. 1-2 As shown, the peracetic acid disinfectant dilution device in this embodiment includes a tank 1, support legs 2, a stirring shaft 3, a drive motor 4, a water inlet 5, a liquid inlet 6, and a drain outlet 7. The support legs 2 are spaced around the bottom of the tank 1 to support the tank 1. The stirring shaft 3 is longitudinally arranged inside the tank 1. The drive motor 4 is located on the top outside of the tank 1 and is connected to the stirring shaft 3 via a coupling 8. The drive motor 4 drives the stirring shaft 3 to rotate, thereby stirring and diluting the liquid inside the tank.

[0021] Water inlet 5 and liquid inlet 6 are respectively located on the top two sides of tank 1, for adding clean water and peracetic acid stock solution into the tank respectively, and a metering pump 9 is provided on liquid inlet 6 for precisely controlling the flow rate of peracetic acid stock solution.

[0022] The drain port 7 is located at the bottom of the tank 1, and the drain port 7 is equipped with a drain valve 10 for discharging the diluted peracetic acid disinfectant out of the tank.

The upper and lower ends of the spiral tube 12 are respectively provided with a water inlet 13 and a water outlet 14. The spiral tube 12 is set close to the outer wall of the tank body 1. During the dilution process, the original liquid will release some heat. By pumping cooling water into the water inlet 13, the cooling water flows along the spiral tube 12, carrying away the heat inside the tank body 1, and finally being discharged through the water outlet 14, so as to achieve the cooling and temperature reduction of the original liquid in the tank.

[0024] A spiral stirring blade 15 is provided around the stirring shaft 3, and the spiral stirring blade 15 is fixedly connected to the stirring shaft 3 via a support rod 16. The spiral stirring blade 15 ensures that the liquid in the tank is fully mixed in all directions, eliminating dead zones and thus diluting the peracetic acid stock solution more evenly and quickly. Furthermore, this spiral stirring structure can adapt to liquids of different concentrations, regardless of their thinness or viscosity, meeting their stirring requirements. Therefore, it is particularly suitable for diluting peracetic acid disinfectants of various concentrations.

[0025] The tank body 1 is provided with a sampling port 17 on one side of the bottom, and a sampling valve 18 is connected to the sampling port 17; a small amount of disinfectant can be obtained through the sampling valve 18 for concentration detection, without stopping the machine for sampling, and the concentration detection efficiency is improved.

[0026] In use, the calculated amount of clean water is first added to the tank body 1 through the water inlet 5, then the peracetic acid stock solution is slowly added to the tank body 1 through the liquid inlet 6, the liquid in the tank is stirred and diluted by the driving motor 4 driving the stirring shaft 3, and the flow of the peracetic acid stock solution is accurately controlled by the metering pump 9, so that the concentration of the disinfectant is accurately controlled, repeated liquid supplementing and testing are avoided, and the dilution efficiency of the disinfectant is improved.
