[0007] Furthermore, the air-drying bin includes a bin body, a bin door, a ventilation window, a support seat, a connecting seat and a sealing groove. The bin doors are provided on the front and rear sides of the bin body, and ventilation windows are symmetrically provided on both sides of the front end of the bin body. A support seat is provided on the top of the bin body, and connecting seats are provided on the left and right sides of the support seat. At the same time, sealing grooves are provided on the top surface of the support seat and the upper end of the inner wall surface.

[0008] Furthermore, the support seat is connected to the warehouse body by welding, and the connecting seat and the support seat are arranged as an integral structure.

Connecting piles are equidistantly arranged on the left and right sides of the upper cover, a filter is provided on the top of the upper cover, and a fan is mounted at the bottom of the filter. Sealing rings are provided on the upper and lower edges of the upper cover.

[0010] Furthermore, the connecting pile and the upper cover are arranged as an integral structure, and the connecting pile and the connecting seat are connected to each other in an inserting structure and fixed by bolts, and the outer surface structure of the sealing ring matches the inner surface structure of the sealing groove.

[0011] Furthermore, the brackets and support columns are arranged alternately and equidistantly with each other, and the support columns are arranged in a circular array structure with the bracket as the center, and the fixing frame is arranged in a circular array structure with the driving motor as the center.

The electric heating structure 5 is installed on the left and right sides of the air-drying bin 1, wherein the driving motor 401 is vertically fixed to the bottom of the fixed beam 3 by using the matching bolts of the fixing frame 402, and at the same time, a plurality of brackets 404 are vertically arranged on the surface of the transmission shaft 403 vertically connected to the bottom of the driving motor 401. With this structural arrangement, under the operation of the driving motor 401, the transmission shaft 403 connected thereto will perform axial rotation in the vertical direction, so that the brackets 404 connected to the transmission shaft 403 will rotate synchronously.

[0026] like Figures 1 to 6As shown, the air-drying bin 1 includes a bin body 101, a bin door 102, a ventilation window 103, a support seat 104, a connecting seat 105 and a sealing groove 106. The bin door 102 is provided on the front and rear sides of the bin body 101, and the ventilation windows 103 are symmetrically provided on both sides of the front end of the bin body 101. A support seat 104 is provided on the top of the bin body 101, and connecting seats 105 are provided on the left and right sides of the support seat 104.

[0027] In summary, if Figures 1 to 6 As shown, when using the air drying equipment for lithium battery manufacturing, first open the doors 102 on the front and rear sides of the bin body 101, then put the lithium battery materials to be processed on the surface of the bracket 404, and ensure that the appropriate number and spacing between them are placed, and then close the doors 102;

[0028] Then, the electric heating structure 5 fixedly installed on the left and right sides of the air-drying bin 1 by the fixing angle plates 504 on the upper and lower sides of the stabilizing frame 503 and the use of bolts is started. Under the operation of the electric heating coil 502, appropriate heat begins to be generated. In this process, since the metal reflective plate 501 is a common heat-reflecting plate with high reflectivity, it can effectively reflect light and heat, so as to ensure that the heat generated by the electric heating coil 502 can be radiated toward the side of the holding rack 4 as much as possible;

[0029] At the same time, the holding rack 4 installed at the bottom of the fixed beam 3 will operate synchronously. Under the drive of the driving motor 401, the transmission shaft 403 connected thereto will rotate axially in the vertical direction, thereby driving the bracket 404 connected thereto and with the lithium battery material placed on the surface to rotate slowly and uniformly to ensure uniform heat conduction;

[0030] During this process, the fan 204 mounted at the bottom of the filter 203 will operate simultaneously, and cooperate with the structural characteristics of the filter 203 to purify and filter the impurities contained in the external air while directing the external air into the air-drying bin 1, thereby ensuring that the lithium battery materials are not affected until the air-drying process is completed. During the processing, the ventilation windows 103 set on both sides of the bin body 101 can discharge excess hot air to avoid the temperature inside the air-drying bin 1 being too high, which may cause unnecessary problems.

[0031] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
