[0026] The specific structure is as follows:

[0027] See also Figure 2 and Figure 3 The air extraction and exhaust mechanism 4 includes an air extraction pump 404 and a fixed sleeve 405. The air extraction pump 404 is purchased from outside and will not be described in detail here. The bottom of the air extraction pump 404 is bolted to the top of the self-heating barrel 1, and the bottom of the fixed sleeve 405 is fixedly connected to the top of the self-heating barrel 1. The bottom of the inner cavity of the fixed sleeve 405 is movably connected with a hollow rod 403 through a sealed bearing. The surface of the hollow rod 403 is movably connected to the connection between the self-heating barrel 1 and the self-heating barrel 1 through a sealed bearing. By setting the fixed sleeve 405, it can be fixedly connected to the self-heating barrel 1, and the fixed installation requirements of the drive motor 3 and the movable installation requirements of the hollow rod 403 are met. The bottom of the hollow rod 403 penetrates into the inner cavity of the self-heating barrel 1. The inner wall of the hollow rod 403 is connected to the rotating rod 401. By setting the rotating rod 401 and the hollow rod 403, it can play an auxiliary stirring role in the rotating state, and the hollow design meets the gas transmission requirements.

[0028] In this embodiment, an integrated seat 8 is provided on the top fixed sleeve of the surface of the hollow rod 403, and there are three stirring blades 5, which are fixedly connected to the integrated seat 8. By setting the stirring blades 5 and the integrated seat 8, they can rotate together with the hollow rod 403, and the battery raw materials at different heights in the self-heating barrel 1 can be stirred by the vertically inclined stirring blades 5.

[0029] See also Figure 2 and Figure 3 The ventilation and heating mechanism 6 includes a mounting sleeve 604, which is embedded in the center of the bottom of the self-heating barrel 1, and the outer ring of the mounting sleeve 604 is fixedly connected to the connection of the self-heating barrel 1.

[0033] The working principle of the utility model is as follows:

[0034] When in use, all components are in the initial installation state. First, a proper amount of battery raw materials - carbon microsphere particles or activated carbon particles are added into the self-heating barrel 1 through the feeding pipe 2, and then the self-heating barrel 1, the driving motor 3, the vacuum pump 404 and the electric heating ring 603 are controlled to work at the same time, wherein the self-heating barrel 1 works to heat up the whole, the driving motor 3 works to drive the hollow rod 403 to rotate, driving the stirring blade 5 and the rotating rod 401 to rotate, and the vacuum pump 404 works to make the gas pass through the installation sleeve 604, the air permeable mesh plate 602, and the air permeable hole 403. 02. The rotating rod 401, the hollow rod 403 and the fixed sleeve 405 transmit, and the electric heating coil 603 works to heat the gas flowing through, so that the heated gas enters the self-heating barrel 1, and dries the battery raw materials stirred by the stirring blades 5 and the rotating rod 401 in the self-heating barrel 1 to form hot air with moisture. The hot air at different positions in the self-heating barrel 1 enters the rotating rod 401 and the hollow rod 403 through the continuously rotating air holes 402, and is finally discharged to the outside to achieve the purpose of uniform drying.

[0035] In summary: the battery raw material drying device, by arranging an exhaust mechanism 4, a stirring blade 5 and a ventilation and heating mechanism 6, solves the problem that the battery raw materials in the device are concentrated at the bottom of the device and cannot be stirred by contacting the stirring element above, and at the same time, the drying uniformity is general and the moisture generated by drying cannot be discharged in time.
