The emulsion tank 1 includes an emulsion oil studio 3 and an emulsion liquid studio 4 arranged side by side. The emulsion oil studio 3 is integrated with a liquid dispensing mechanism 5 outside the emulsion oil studio 3. The liquid dispensing mechanism 5 includes a water inlet solenoid valve 6, an oil pump 7 and a circulation pump 8. The emulsion liquid studio 4 is provided with a concentration sensor 9 and a liquid level sensor 10 for detecting the internal medium concentration and water level. The oil extraction pipe 11 of the oil pump 7 is connected to the emulsion oil studio 3. The oil inlet pipe 12 of the oil pump 7 is used to replenish oil to the emulsion liquid studio 4. One end of the water inlet solenoid valve 6 is connected to a water source, and the other end of the water inlet solenoid valve 6 replenishes water to the emulsion liquid studio 4. The circulation pump 8 is used to promote the flow of the medium in the emulsion liquid studio 4 to promote oil-water mixing. In this embodiment, the end of the water inlet solenoid valve 6 away from the emulsion liquid studio 4 can be connected to an external water source or a liquid pump. The concentration sensor 9 and the liquid level sensor 10 are commercially available, and the working principle is not specifically described.

[0020] Working principle: When the liquid level in the emulsion tank 1 drops to the set low liquid level, the liquid level sensor 10 sends a liquid replenishment signal to the electric control box 2. After the electric control box 2 receives the signal, the water inlet solenoid valve 6 is opened to replenish water into the emulsion tank 1. At the same time, the circulation pump 8 is turned on to realize the flow of internal medium. The concentration of the mixed liquid in the emulsion working room 4 is detected in real time by the concentration sensor 9. After the electric control box 2 receives the concentration signal, if the concentration is lower than the set low concentration value, it sends a start signal to the oil pump 7 to start the oil pump 7 to replenish oil into the emulsion working room 4, stop after a period of time, and then continue to detect the concentration until the concentration of the mixed liquid in the emulsion working room 4 reaches the set high concentration value, completing a liquid replenishment and liquid preparation procedure.

[0021] The circulation pump 8 is connected to the left side of the emulsion working room 4 through the liquid extraction pipe 25, and the other end of the circulation pump 8 is connected to the water inlet pipe 24 on the right side of the emulsion working room 4 through a hose, so as to promote the circulation of the internal mixed liquid and ensure the mixing of the oil.

[0022] An adapter 13 is provided on the side of the emulsion working room 4 facing the liquid dispensing mechanism 5. The adapter 13 has a water inlet end 14 directly or indirectly connected to the water inlet solenoid valve 6 and an oil inlet end 15 connected to the oil inlet pipe 12. There is no need to open more holes on the box body. The water inlet solenoid valve 6 and the oil pump 7 are connected at the same time through one adapter 13.

[0023] A filter chamber 16 connected to the adapter 13 is provided on the emulsion studio 4, and an opening 17 is provided below the filter chamber 16. The filter chamber 16 is located at the top of the emulsion studio 4. A detachable filter screen 18 is provided on the inner wall of the filter chamber 16 to filter the oil entering the emulsion studio 4 to prevent impurities from entering the emulsion tank 1 and causing pipeline blockage.

[0024] In this embodiment, the filter chamber 16 is a rectangular frame 19 integrally formed on the inner wall of the emulsion working chamber 4 , and a detachable cover plate 20 is provided on the top of the filter chamber 16 .
