[0027] In this embodiment, the cart 1 is provided with an armrest and a roller at the bottom of the cart 1. The cart 1 can be moved by pushing the armrest. Alcohol is selected as the cleaning agent, and water or other cleaning solvents can also be selected. The filtration accuracy of the first filter 7 and the second filter 8 is 60um. When cleaning is required, the drain valve 10 is first closed, and the first reversing switch 5 is used to connect the cleaning pipeline 2 with the storage tank 4. The second reversing switch 6 is used to connect the cleaning pipeline 2 with the hose. Then, one end of the hose is connected to the other end of the cleaning pipeline 2, and the other end of the hose is connected to the tank to be cleaned. Then connect the air source to the inlet of the air inlet valve 9, and then open the air inlet valve 9. When the pressure of the storage tank 4 is greater than the tank pressure of the tank to be cleaned, the cleaning agent flows from the storage tank 4 to the cleaning pipe 2, and passes through the cleaning pipe 2 through the hose to reach the inside of the tank to be cleaned for cleaning. When the cleaning inside the tank is completed, the first reversing switch 5 is used to reverse the direction so that the drain pipe 3 is connected to the storage tank 4, and the second reversing switch 6 is used to reverse the direction so that the drain pipe 3 is connected to the hose. Then open the air inlet valve 9 to ensure normal pressure in the storage tank 4, and then give a certain air pressure to the cleaned tank. Then the cleaning agent and impurities flow into the drain pipe 3, and flow into the storage tank 4 after being filtered by the second filter 8. When the refined wine at the bottom of the storage tank is not clean, you can open the drain valve 10 and connect the hose for draining.
