[0029] The regulating component 2 is arranged inside the heat exchange tube 10. The regulating component 2 can control the flow of water vapor inside the heat exchange tube 10, so that the wastewater inside the wastewater pool 1 can be heated, so that the flocculant can react better with the wastewater at a certain temperature;

[0030] The stirring component 3 is rotatably connected to the annular outer surface of the heat exchange tube 10 to stir the wastewater in the wastewater pool 1 in a rotating manner, thereby further improving the mixing effect of the wastewater and the flocculant.

A driving wheel 26 is connected to the upper end of the driving rod 29, and the driving wheel 26 is in contact with the belt 25. The driving wheel 26 is driven by the motor 20 to rotate, and the driven wheel 24 and the threaded rod 241 are driven by the belt 25 to rotate, so as to adjust the height of the adjusting rod 23 inside the adjusting tube 22, thereby changing the height of the adjusting cone 21 at the lower end opening of the heat exchange tube 10, thereby realizing the adjustment of the flow rate inside the heat exchange tube 10. The user can adjust the steam flow inside the heat exchange tube 10 according to the usage.

[0032] Embodiment 2

[0033] A spring three 40 is fixedly connected between the regulating tube 22 and the regulating rod 23. The spring three 40 is made of a memory alloy. When the temperature is too high, the spring three 40 will automatically shrink, thereby pulling the regulating cone 21 to move upward to reduce the flow inside the heat exchange tube 10. If the temperature to which the spring three 40 is subjected is restored, it will automatically reset, so that the regulating cone 21 moves downward along the heat exchange tube 10, and the heat exchange tube 10 is restored to the maximum flow. The flow of the heat exchange tube 10 is automatically controlled by the spring three 40 made of the memory alloy.

[0034] The stirring assembly 3 includes a friction ring 32, which is rotatably connected to the outer surface of the heat exchange tube 10 through a bearing. A stirring plate 31 is provided at the lower end of the friction ring 32. The driving rod 29 passes through the motor 20. A friction plate 2 35 is connected to the lower end of the driving rod 29. The friction plate 2 35 is in contact with the friction ring 32. The driving rod 29 is driven by the motor 20 to drive the friction plate 2 35 to rotate. The edges of the friction plate 2 35 and the friction ring 32 are both designed with inclined structures. When the motor 20 is started, the friction ring 32 is driven to rotate through the friction plate 2 35, thereby driving the stirring plate 31 to rotate inside the wastewater pool 1 to stir the wastewater inside so that it is better mixed with the flocculant.

[0035] A telescopic groove 36 is provided on the outer surface of the lower end of the friction ring 32, and a telescopic plate 37 is slidably connected inside the telescopic groove 36.

When the stirring plate 31 starts to rotate driven by the friction ring 32, the inside of the wave groove 30 is slidably connected to the slider 38. When the stirring plate 31 rotates, the slider 38 forces the stirring plate 31 to rise and fall under the restriction of the wave groove 30, and cooperates with the stirring plate 31 with a T-shaped structure to further increase the stirring of the flocculant. The arrangement of the telescopic plate 37 and the telescopic groove 36 ensures the vertical displacement of the stirring plate 31.

A friction plate 27 is slidably connected to the upper end of the driving rod 29, and a spring 28 is fixedly connected between the friction plate 27 and the electromagnet 291. Since the driving rod 29 passes through the motor 20, in order to prevent the adjustment component 2 and the stirring component 3 from interfering with each other, the friction plate 27 is made of magnetic material and repel each other with the electromagnet 291. When it is necessary to drive the driving wheel 26 to rotate, the electromagnet is energized to push the friction plate 27 to move upward and fit together with the driving wheel 26, and drive it to rotate through friction. The spring 28 can reset the friction plate 27 after the electromagnet is powered off.

[0037] The driving rod 29 is slidably connected to the friction plate 35. The annular outer surface of the driving rod 29 is fixedly connected to the electromagnet 33. A spring 34 is fixedly connected between the electromagnet 33 and the friction plate 35. The friction plate 35 is also made of magnetic material. When the stirring assembly 3 is needed to stir the wastewater, the electromagnet 33 is energized to push the friction plate 35 to contact the friction ring 32, and the friction ring 32 is driven to rotate by friction. The setting of the spring 34 can reset the friction plate 35 when the electromagnet 33 is powered off.
