[0023] Referring to Figure 1 , Figure 2 and Figure 4 , a preparation device based on lithium ion battery diaphragm includes a heating barrel 1 and a heat preservation barrel 2. The heating barrel 1 is provided with the heat preservation barrel 2 on the side. The heating barrel 1 and the heat preservation barrel 2 are connected through the gas guide pipe 7 between the top of the heating barrel 1 and the top of the heat preservation barrel 2. The inner walls of the heating barrel 1 and the heat preservation barrel 2 at both ends of the gas guide pipe 7 are fixed with filter screens. The gas guide pipe 7 is located above the top of the feeding pipe two 12. The top surfaces of the heating barrel 1 and the heat preservation barrel 2 are both connected with the feeding port 3. The bottom of the heating barrel 1 away from the heat preservation barrel 2 is connected with the discharge port 16. The heat preservation barrel 2 is fixed with the inner preheating barrel 8 inside. The feeding port 3 on the top surface of the heat preservation barrel 2 penetrates into the inside of the inner preheating barrel 8. The outer side of the inner preheating barrel 8 and the inner side of the heat preservation barrel 2 form the preheating cavity 9. The gas guide pipe 7 is connected with the inside of the preheating cavity 9. The bottom of the heat preservation barrel 2 away from the heating barrel 1 is fixed with the water outlet 15 connected with the preheating cavity 9. The water outlet 15 is connected with the water storage pool through the water pipe. The bottom surface of the water outlet 15 is flush with the bottom surface of the preheating cavity 9.

[0024] The inner preheating barrel 8 is fixed with a feeding pipe 10 on the front side, and the feeding pipe 10 extends to the outside of the heat preservation barrel 2 and is fixed on the input end of the feeding pump 11. The output end of the feeding pump 11 is fixed with a feeding pipe 12. The inner preheating barrel 8 is made of heat-conducting material. The outer surfaces of the heat preservation barrel 2, the gas guide pipe 7, the feeding pipe 10 and the feeding pipe 12 are fixed with a heat preservation coating. The end of the feeding pipe 12 away from the feeding pump 11 is fixed on the upper part of the heating barrel 1. The heating barrel 1 and the heat preservation barrel 2 are both provided with stirring assemblies.

[0025] Specifically, when heating in the heating barrel 1, the steam generated by heating enters the preheating cavity 9 through the gas guide pipe 7 and preheats the raw materials in the inner preheating barrel 8. After heat exchange, the steam is liquefied into water and discharged through the water outlet 15. After the raw materials in the heating barrel 1 are heated, the preheated raw materials in the inner preheating barrel 8 are input into the heating barrel 1 through the feeding pipe 10, the feeding pump 11 and the feeding pipe 12 for continuous heating. Raw materials are added to the inner preheating barrel 8 through the feeding inlet 3 for continuous operation.

[0026] As an optimization scheme, as shown in Figure 3 and Figure 4 The stirring assembly includes a stirring rod 6 and a stirring rod 13. The heating barrel 1 is fixedly installed with a motor 4 above, and the motor 4 is fixed with a driven wheel 5 at the output end. The driven wheel 5 is fixed with the stirring rod 6 at the end away from the motor 4. The stirring rod 6 is rotatably connected with the inside of the heating barrel 1 through a bearing. Another driven wheel 5 is arranged on the top surface of the heat preservation barrel 2. Another motor 4 is fixed with a stirring rod 13 at the bottom surface. The diameters of the stirring rod 6 and the stirring rod 13 are smaller than the diameters of the inside of the heating barrel 1 and the inner preheating barrel 8. The upper and lower ends of the inner preheating barrel 8 are fixed on the inner wall of the heating barrel 1. The stirring rod 13 is rotatably connected with the inside of the heat preservation barrel 2 through a bearing. The two driven wheels 5 are drivingly connected through a belt 14.

[0027] Specifically, when the heating barrel 1 is heated and the heat preservation barrel 2 is preheated, the motor 4 is turned on to drive the driven wheel 5 to rotate, which drives the other driven wheel 5 to rotate through the belt 14. The rotation of the two driven wheels 5 drives the stirring rod 6 and the stirring rod 13 to rotate. When the stirring rod 6 and the stirring rod 13 rotate, the heated slurry and the preheated raw materials can be stirred to make them more evenly heated.
