The upper branch pipe 11 and the lower branch pipe 13 are connected by a connecting pipe 15, and the upper branch pipe 27 and the lower branch pipe 21 are connected by a connecting pipe 29. The upper branch pipe 11, the lower branch pipe 13, the connecting pipe 15, the upper branch pipe 27, the lower branch pipe 21, and the connecting pipe 29 can all be switched on and off. The upper branch pipe 11 and the lower branch pipe 13 are connected to the outside of the tank body 2. 13. Connecting pipe 15, upper branch pipe 21, lower branch pipe 21, and connecting pipe 29 are respectively connected to a first solenoid valve 12, a second solenoid valve 14, a third solenoid valve 16, a fourth solenoid valve 18, a fifth solenoid valve 22, and a sixth solenoid valve 20. It also includes an L-shaped aeration pipe 6. The end of the aeration pipe 6 that passes through the tank 2 to the outside is connected to a pump body 7. The pump body 7 is connected to an air inlet pipe 8. A one-way valve is connected inside the air inlet pipe 8. A filter element is connected to the air inlet pipe 8. An exhaust pipe is connected to the tank 2. A pressure relief valve is connected to the exhaust pipe. The tank 2 and the pump body 7 are both fixedly connected to the connecting frame. The bottom of the tank 2 is connected to an L-shaped discharge pipe 9. A manual valve 10 is connected to the discharge pipe 9.

[0026] It also includes a first flow sensor, a second flow sensor, a first voltage comparator circuit, a second voltage comparator circuit, and a controller. The controller includes an STM32F103RCT6 embedded microcontroller. The probe of the first flow sensor is disposed in the upper branch tube 11, and the probe of the second flow sensor is disposed in the upper branch tube 17. The output terminal of the first flow sensor is coupled to the input terminal of the first voltage comparator circuit, and the output terminal of the second flow sensor is coupled to the input terminal of the second voltage comparator circuit. The output terminals of both the first and second voltage comparator circuits are coupled to the input terminal of the controller. The output terminal of the controller is coupled to the third solenoid valve 16 and the sixth solenoid valve 20 through the first and second relays, respectively. Both the first and second voltage comparator circuits include voltage comparators.

[0027] A vertically arranged drive motor 5 is fixedly connected to the top surface of the cover 3 via a connecting seat 4. The output shaft of the drive motor 5 passes through the connecting seat 4 and the cover 3 to the tank body 2. The output shaft of the drive motor 5 is fixedly connected to a stirring paddle located inside the tank body 2.

[0028] When preparing environmentally friendly water-based paint, this invention allows the solvent, water-based resin, pigments, and fillers of the environmentally friendly water-based paint to be added into tank 2 through the opening at the top of tank 2. The opening of tank 2 is then sealed with a cap 3, allowing the stirring paddle to enter tank 2. The drive motor 5 then starts working, rotating its output shaft, which in turn causes the stirring paddle to agitate and mix the solvent, water-based resin, pigments, and fillers of the environmentally friendly water-based paint within tank 2. To accelerate the mixing efficiency, the pump 7 is then activated. After the outside air is filtered through the filter element in body 7, it is guided into the aeration pipe 6 by the one-way valve. The aeration pipe 6 aerates the solvent, water-based resin, pigments, and fillers of the environmentally friendly water-based paint in tank 2, thereby accelerating the mixing of the various raw materials of the environmentally friendly water-based paint. Afterwards, various additives are input through upper branch pipe 11, lower branch pipe 13, upper branch pipe 27, and lower branch pipe 21. The first flow sensor and the second flow sensor detect the flow rate of the additives in upper branch pipe 11 and upper branch pipe 27, respectively. There is also a first voltage comparison circuit and a second voltage comparison circuit. The voltage comparison circuit compares the signals. If the first flow signal output by the first flow sensor is less than the first reference signal in the first voltage comparison circuit, a first comparison signal is sent to the controller. Similarly, if the second flow signal output by the second flow sensor is less than the second reference signal in the second voltage comparison circuit, a second comparison signal is sent to the controller. The controller can control the third solenoid valve 16 and the sixth solenoid valve 20 via the first and second relays respectively. That is, if the additive flow rate in the upper branch pipe 11 or the upper branch pipe 27 is low, then it is necessary to open the connecting pipe 15 or the connecting pipe 20. Connect pipe 2 19 to mix the additives in the upper branch pipe 11 with the additives in the lower branch pipe 13. The mixed additives are then mixed with the main water-based paint raw materials from below the tank 2 through the lower branch pipe 13. Similarly, the additives in the upper branch pipe 2 17 are mixed with the additives in the lower branch pipe 2 21. The mixed additives are then mixed with the main water-based paint raw materials from below the tank 2 through the lower branch pipe 2 21. In this way, the additives can directly enter the tank 2 and mix with the environmentally friendly water-based paint near the aeration pipe 6 below, so that the equipment can complete the preparation of the annular water-based paint in a shorter time.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
