[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0020] like Figures 1 to 8 As shown, a high-viscosity ion exchange resin slurry mixing device includes an air pump 1, a storage tank 2, a proportioner 3 and a stirring device 4. The storage tanks 2 are connected by air pipes, that is, the storage tanks 4 are in a connected state, that is, the internal air pressure remains consistent, but the materials are not mixed with each other, and the output end of the air pump 1 is connected to the air pipe. When the air pump 1 is working, it pumps gas into the storage tank 4, and the gas in the storage tank 2 is pressed out by increasing the air pressure. In addition, an air pressure sensor and an overflow valve are also provided in the air pipe to ensure that the air pressure in the storage tank 2 is in a safe state. The proportioner 3 is arranged between the storage tank 2 and On the material pipe between the stirring devices 4, and on the proportioner 3, a plurality of baffles 33 are arranged, and holes 34 with different apertures are arranged in the middle of each baffle 3. During the process of pressure feeding, the material passes through the proportioner 3, that is, through the holes 34 with different apertures. Therefore, when the outlet diameters of the two connected containers are different, the relationship between the flow ratio and the diameter ratio per unit time can be obtained through Poiseuille's law in fluid mechanics. Because various materials are pressed out under the same air pressure, it can be regarded that when the material passes through the hole 34, its pressure is equal. Therefore, by controlling the aperture of the hole 34, the requirements of the on-demand proportioning of various materials can be achieved. This structure has the advantage of being able to perform real-time proportioning of materials. At the same time, compared with the metering pump, the feeding accuracy of the metering pump is mainly determined by the rotation speed of the impeller, which is more complicated to control, while the proportioning of materials in this scheme is relatively simple as a whole and easy to achieve.
[0021] The stirring device 4 includes a temporary storage tank 44, which is a cylindrical structure. A stirring drum 47 is fixedly connected to the bottom of the temporary storage tank 44, and the stirring drum 47 extends to the interior of the temporary storage tank 44. Specifically, the stirring drum 47 is embedded in the interior of the temporary storage tank 44, and only the lower end portion is exposed from the stirring drum 47.

The first motor 41 drives the stirring impeller 46 to rotate, and then various materials enter from the lower part of the stirring drum 47 and flow upward. During the process, the rotating stirring impeller 46 stirs and shears the materials, and finally sends them out from the overflow hole 410.
[0022] The storage tank 2 includes a tank body 21, both ends of which are hemispherical structures. The upper side wall of the tank body 21 is provided with a first discharge port 22 and a first feed port 23, which are respectively used for the delivery and entry of materials. A connecting air port 24 is provided at the upper end of the tank body 21, and the connecting air port 24 is connected to the air pipe. The connecting air port 24 is set at the upper end of the tank body 21 to prevent the material from entering other tank bodies 21.
[0023] Furthermore, the raw materials of the slurry for preparing the ion exchange membrane contain solids, so the solid raw materials need to be dissolved before being sent to the storage tank 2.

A floating block 26 is slidably provided on the guide column 25. Under the restriction of the guide column 25, the floating block 26 is ensured to float up and down.

The provision of the floating block 26 and the connecting hose 27 ensures that the lower end of the connecting hose 27 is as close to the liquid surface of the material as possible, that is, the pressure of the material delivered from each storage tank 2 is ensured to be consistent, and the proportioning accuracy of the proportioner 3 is further improved.
[0025] The proportioner 3 includes a plate body 31, which is a rectangular metal piece as a whole. A plurality of through holes are arranged on the plate body 31, and a convex ring 310 is arranged on the middle inner wall of the through hole. The baffle 33 is located on one side of the convex ring 310. The front and back sides of the through hole are respectively threadedly connected with a front connector 32 and a rear connector 39. The front connector 32 and the rear connector 39 are both used to connect pipelines. If necessary, the rear connector 39 is disassembled and the baffle 33 is replaced, that is, the holes 34 with different apertures are replaced to meet the proportioning needs of various materials.
[0026] A sealing gasket 37 is provided between the convex ring 310 and the baffle 33 to seal the two.

A second discharge port 43 is provided on the lower side wall of the temporary storage tank 44, and the stirred material is discharged from the second discharge port 43 for use. The second discharge port 43 is set at the bottom, and its purpose is that the material enters the mixing drum 47 from the bottom, is stirred while rising, and then flows out from the overflow hole 410, and finally flows downward and is discharged from the second discharge port 43. During the process, the material circulates at different levels, and the material is fully mixed to a certain extent.
[0029] A plurality of scrapers 49 are vertically arranged inside the temporary storage tank 44, and the edges of the scrapers 49 are in contact with the temporary storage tank 44. When the scrapers 49 are in operation, the materials adhering to the inner wall of the temporary storage tank 44 are scraped off. Connecting rings 48 are fixedly connected to the scrapers 49 at equal intervals. The connecting rings 48 combine the scrapers 49 into a whole and improve the structural strength of the whole.
