[0038] Embodiment 2:

[0039] On the basis of Example 1, before a flocculant reaction tank with an automatic feeding function starts working, the base liquid, acid liquid and alkali liquid required for preparing the flocculant are first injected into the base liquid storage tank 803, the acid liquid storage tank 801 and the alkali liquid storage tank 802 respectively, and the flocculant preparation program is set through the main control box 3. The flocculant reaction tank with an automatic feeding function starts working, and the main control box 3 controls the base liquid flowmeter 709 to open. The base liquid in the base liquid storage tank 803 flows through the base liquid conduit 808 through the base liquid flowmeter 709 and is injected into the base liquid feed port 704, and finally enters the tank body 1. At the same time, the driving motor 701 is started, and the driving motor driving shaft 707 drives the driving stirring guide rod 9 to start rotating, and the stirring blade 10 stirs the base liquid in the tank body 1. The liquid level measuring rod 11 measures the liquid level in the tank body 1, and feeds back the liquid level information to the main control box 3. The main control box controls the driving power of the driving motor according to the liquid level information.

[0040] The oil heat control box 5 heats the heating oil and drives the heating oil into the tank wall cavity 101 through the oil supply pipe 503. The heating oil fills the tank wall cavity 101 and heats the base liquid in the tank body 1. Finally, it returns to the oil heat control box 5 along the return oil pipe 502 to form a closed loop. When the base liquid in the tank body 1 is heated to the set temperature, the main control box 3 controls the acid flow meter 809 to open, and the acid in the acid storage bin 801 flows through the acid flow meter 809 through the acid conduit 804 and enters the acid feed port 703, and finally enters the tank body 1. When the amount of acid put into the tank body 1 reaches the set value, the main control box 3 controls the acid flow meter 809 to close.

[0041] At this time, if the pH value of the mixed liquid in the tank body 1 is more alkaline than the set value, the main control box 3 controls the acid flowmeter 809 to open slightly, and injects a small amount of acid. When the pH value of the mixed liquid in the tank body 1 is adjusted to the set value, the acid flowmeter 809 is closed. At this time, if the pH value of the mixed liquid in the tank body 1 is more acidic than the set value, the main control box 3 controls the alkaline flowmeter 807 to open, and the alkali liquid in the alkali liquid storage bin 802 flows through the alkali liquid flowmeter 807 through the alkali liquid conduit 805 and enters the alkali liquid feed port 705, and finally enters the tank body 1. When the pH value of the mixed liquid in the tank body 1 is adjusted to the set value, the main control box 3 controls the alkali liquid flowmeter 809 to close.

[0042] The oil heat control box 5 continuously heats the mixed liquid in the tank body 1 by heating oil, so that its temperature is always maintained within the set temperature range. The main control box controls the driving power of the driving motor 701 according to the temperature, pH value and liquid level information of the mixed liquid in the tank body 1, so that the stirring guide rod 9 drives the stirring blade 10 to stir the mixed liquid at a certain speed, so that the preparation reaction of the flocculant is completed in the best state.

[0043] As the flocculant preparation reaction continues, the pH value of the mixed liquid in the tank 1 will change. The main controller 3 adds an appropriate amount of acid or alkali liquid to the mixed liquid in the tank 1 by opening and closing the acid flowmeter 809 and the alkaline flowmeter 807 to maintain the pH value of the mixed liquid in the tank 1.

[0044] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
