The methanol-water solution supply system with cleaning and stirring functions according to claim 1, characterized in that: The isolation assembly comprises: An isolation plate (5), the isolation plate (5) being arranged on the inner wall of the mixing tank (1) and located at the bottom of the mixing assembly; A discharge valve (501), the discharge valve (501) is connected to the bottom of the isolation plate (5), and the discharge valve (501) is used to control the temporary discharge and storage of the mixed methanol-water solution; A discharge pipe (105), the discharge pipe (105) is arranged at the bottom of the mixing tank (1), and the discharge pipe (105) is used for temporarily storing the methanol-water solution; A clean water outlet pipe (104), the clean water outlet pipe (104) being arranged on the side of the discharge pipe (105), and the clean water outlet pipe (104) being used for the outflow of clean water; A rotating part, the rotating part is used to open and close the liquid discharge valve (501), and the rotating part is inserted and connected to the outside of the mixing tank body (1).

9. A methanol aqueous solution supply system with cleaning and stirring functions according to claim 8, characterized in that: The rotating part comprises: A rotating rod (502), the rotating rod (502) is inserted and connected to the side of the mixing tank body (1), and the end of the rotating rod (502) is fixedly connected to the rotating opening and closing end of the liquid discharge valve (501); A hand wheel (503), wherein the hand wheel (503) is arranged at the end of the rotating rod (502) and is located outside the mixing tank body (1).

10. A method for using a methanol-water solution supply system with cleaning and stirring functions, using the supply system according to any one of claims 1 to 9, characterized in that: The method of use includes the following steps: In the first step, the device is powered on, and the direct stirring part in the mixing assembly starts to rotate, and the direct stirring part drives the centrifugal part to rotate in the mixing tank (1); In the second step, the closed component is connected to the pressure supply pipeline of methanol and water, so that the raw material pressure flow enters the supply system and then enters the polymerization discharge part at the bottom of the closed component. The polymerization discharge part injects methanol and water into the centrifugal part. The rotating centrifugal part collides and mixes the methanol and water, and the methanol and water fly out of the centrifugal part due to the centrifugal force. In the third step, the methanol preliminary mixed aqueous solution flying out of the centrifugal part is gathered in the inner cavity of the mixing tank body (1) and at the top of the isolation component, and the rotating direct stirring part finally mixes the methanol preliminary mixed aqueous solution and enters the isolation component to be temporarily stored in the bottom inner cavity of the mixing tank body (1), and the methanol final mixed aqueous solution is discharged from the mixing tank body (1) through the isolation component for use; In the fourth step, only water is introduced into the closed component to clean the centrifugal part, the polymerization discharge part, the direct stirring part, the isolation component and the inner wall of the mixing tank (1), and then discharged from the isolation component to perform self-cleaning of the system.
