[0033] In this embodiment, the frame 1 is used to install and support the stirring assembly. The water purification shell 2 is used to form a chemical wastewater storage space, and the chemical wastewater and the reagents required for purification are injected into the water purification shell 2, and then the chemical wastewater and the reagents are fully mixed through the stirring mechanism 3, so that the harmful impurities in the chemical wastewater can fully react with the reagents and improve the impurity removal efficiency. The driving member 4 is the power source of the stirring mechanism 3, which generates power through electricity to drive the stirring shaft 301 and the blades 303 to rotate or reciprocate.

[0034] In this embodiment, the above-mentioned drug delivery component is used to transport the liquid drug at different depths in the water purification shell 2 through the liquid separation mechanism 9, which is convenient for rapid mixing of the drug and wastewater and can greatly improve the mixing efficiency; in addition, clean water can also be transported through the liquid separation mechanism 9 for cleaning the stirring component and the inside of the water purification shell 2, with high cleaning efficiency.

[0035] Furthermore, the liquid storage tank 7 is used to store the prepared water purification agent, the delivery pipeline 8 is used to process the water purification agent and deliver it into the water purification shell 2, and the liquid separation mechanism 9 is used to output the water purification agent at different height positions in the water purification shell 2, so as to facilitate the rapid dispersion of the water purification agent in the water purification shell 2, thereby greatly improving its mixing efficiency and improving the water purification efficiency.

[0036] Please refer to Figure 1 and Figure 4 In some implementations of the present embodiment, the stirring mechanism 3 includes a stirring shaft 301, a swing rod 302 and blades 303.

The centrifugal force generated by the rotating stirring shaft 301 moves the swing rod 302 from being attached to the outer wall of the stirring shaft 301 to swinging perpendicular to the stirring shaft 301. The shear force and turbulence generated by the swing rod 302 achieve uniform mixing of the medicine and industrial wastewater, so that the active ingredients in the medicine can effectively react with the impurities in the wastewater.

The servo motor can control the speed, and the position accuracy is very accurate. It can convert the voltage signal into torque and speed to drive the control object. The excellent control accuracy of the servo motor is the offline material of the driving member 4, but it is not limited to the above-mentioned servo motor material, and can also be other materials with similar performance.

[0043] Please refer to Figure 1 and Figure 3 In some implementations of this embodiment, a booster pump 10 for increasing the liquid pressure is connected in series to the delivery pipeline 8 .

[0044] In this embodiment, the booster pump 10 is used to increase the pressure of the water purification agent delivered to the liquid separation mechanism 9, so that the water purification agent can actively diffuse when delivered to the water purification shell 2, thereby improving the efficiency of the water purification agent diffusion and thus improving the efficiency of water purification.

[0045] Please refer to Figure 1 and Figure 3 In some implementations of the present embodiment, a cleaning pipe 11 for conveying clean water to the inner cavity of the purification shell 2 is provided on the above-mentioned delivery pipe 8, and a control valve 12 is connected in series to the cleaning pipe 11.

[0046] In this embodiment, the above-mentioned cleaning pipe 11 is used to transport water to clean the water purification shell 2 and the stirring mechanism 3, so as to facilitate the input of clean water to clean the inner wall of the water purification shell 2 after use, and avoid the chemical wastewater remaining on the surface from corroding the water purification shell 2 and the stirring mechanism 3, thereby improving the service life of the water purification system.

[0047] When in use, the cleaning pipe 11 is connected to the tap water pipe, and then the control valve 12 is opened. Clean tap water is transported to the clean water shells 2 at different heights through the liquid separation mechanism 9, thereby flushing the clean water shell 2 and the stirring mechanism 3 to achieve automatic cleaning.

[0048] Please refer to Figure 1 In some implementations of this embodiment, the liquid storage tank 7 is a transparent structure.

[0049] In this embodiment, the liquid storage tank 7 adopts a transparent structure, so that the user can observe the liquid level of the medicine stored in the liquid storage tank 7 in real time, and the user can add medicine according to his / her usage needs.

[0050] When in use, the control valve 12 connected in series on the cleaning pipe 11 is closed, and an appropriate amount of agent for purifying industrial wastewater is added to the liquid storage tank 7. The pre-treated industrial wastewater is connected to the water inlet pipe 5, and the drainage pipe 6 is connected to the next water purification process. The water body is controlled to stay in the water purification shell 2, and then the booster pump 10 and the stirring mechanism 3 are driven to work simultaneously to transport the liquid agent in the liquid storage tank 7 to the liquid separation mechanism 9. The liquid separation mechanism 9 disperses the agent in different height spaces of the water purification shell 2 through the liquid feeding ring 901. Under the rotation of the stirring shaft 301, the swing rod 302 of the stirring mechanism 3 is separated from the stirring shaft 301 to form a larger stirring area, which accelerates the mixing of the agent and the industrial wastewater, and finally transports the agent and the industrial wastewater to the next operation process; when cleaning the water purification shell 2, the booster pump 10 is controlled to be closed, the control valve 12 is opened, and the clean water is transported to the liquid separation shell and the stirring mechanism 3 through the liquid separation mechanism 9, and the impurity water body is output through the drainage pipe 6.
