The principle of applying the integrated system and method for adhesive removal and discharge in other types of equipment is essentially the same as the principle applied in the field of power battery recycling technology, which will not be elaborated here.

[0022] See also Figure 1 , Figure 1 1 is a structural schematic diagram of an integrated system and method for degumming and discharging in one embodiment of the present invention. The integrated system for degumming and discharging includes a reactor 1, a medium component 2, a valve component 3 and a stirring component 4. A accommodating chamber 11 for accommodating materials is formed inside the reactor 1. The medium component 2 includes a first medium tank 21 and a second medium tank 22.

The valve component 3 is arranged between the reactor 1 and the first medium tank 21 or the second medium tank 22, and is used to add discharge media or degumming media into the reactor 1. The stirring component 4 includes a high-speed disperser 41. The high-speed disperser 41 has a fixed end and a rotating end.

[0042] During the process of the rotating end of the high-speed disperser 41 rotating relative to the fixed end thereof, the discharge medium or the degumming medium can be effectively promoted to contact with the battery core, thereby improving the production efficiency.

[0043] Furthermore, in order to prevent the rotating end of the high-speed disperser 41 from colliding with the material barrel 5 or the kettle body 12 when rotating with the sealing cover 13, the sealing cover 13 is opened or closed by moving closer to or away from the kettle body 12 in the vertical direction, which will not be elaborated here.

[0048] The floating ball 63 drives the sliding rod 62 to slide relative to the transparent cover 61 to reflect the depth of the liquid level in the reactor 1, which is convenient for users to observe.

[0049] Furthermore, the float 63 here is a small hollow ball that is common and easy to purchase on the market. It can float on the liquid level and rise and fall with the change of the liquid level. The float 63 here belongs to a conventional setting well known to technical personnel in this field and will not be described in detail here.
