[0066] like Figures 1-6 As shown, according to the first aspect of the embodiment of the present application, a stirring device 100 is provided, comprising a shell 1, wherein the shell 1 comprises a first section 11, a second section 12 and a third section 13 connected in sequence, wherein a first accommodating chamber 11a, a second accommodating chamber 12a and a third accommodating chamber 13a are formed in communication with each other inside the shell 1, wherein the first accommodating chamber 11a is located inside the first section 11, the second accommodating chamber 12a is located inside the second section 12, and the third accommodating chamber 13a is located inside the third section 13; A first interlayer 111 is provided between the inner wall and the outer wall, and the first interlayer 111 is a cooling layer, which cools the first accommodating cavity 11a; a second interlayer 121 is provided between the inner wall and the outer wall of the second section 12, and the second interlayer 121 is a heating layer, which heats the second accommodating cavity 12a; a third interlayer 131 is provided between the inner wall and the outer wall of the third section 13, and the third interlayer 131 is a cooling layer, which cools the third accommodating cavity 13a.

[0067] The stirring device 100 of the present application can be used for mixing dry electrode materials, and can also be used for mixing other powder materials. The embodiment of the present application is described by taking dry electrode material mixing as an example.

[0068] like Figure 1-Figure 3 As shown, the stirring device 100 includes a shell 1, which includes a first section 11, a second section 12 and a third section 13 connected in sequence. A first accommodating chamber 11a, a second accommodating chamber 12a and a third accommodating chamber 13a are formed inside the shell 1. The first accommodating chamber 11a is located inside the first section 11, the second accommodating chamber 12a is located inside the second section 12, and the third accommodating chamber 13a is located inside the third section 13.

Specifically, the inner wall of the second section 12 is located in the second accommodating cavity 12a, and the second interlayer 121 is a heating layer.

Specifically, the inner wall of the third section 13 is located in the third accommodating cavity 13a, and the third interlayer 131 is a cooling layer for cooling the third accommodating cavity 13a to cool the fiberized mixed material to facilitate discharge of the third section 13.

[0070] In the related art, the shell 1 of the stirring device 100 has a accommodating chamber, in which mixing is first performed, and then the mixture is fiberized after the mixing is completed, and then the fiberized mixture is discharged. Therefore, the accommodating chamber needs to be cooled during mixing, heated during fiberization, and cooled during discharge of the fiberized mixture; constant cooling, heating, and cooling alternation will reduce the working efficiency of the stirring device 100.

[0071] Therefore, the stirring device 100 provided in the present application carries out mixing, fiberization of the mixture, and buffering of the fiberized mixture for discharge in different containing chambers respectively, and cools the first containing chamber 11a, heats the second containing chamber 12a, and cools the third containing chamber 13a without the need for replacement, thereby improving the working efficiency of the stirring device 100.

The cooling mechanism cools the reflux cooling liquid and then outputs it from the first inlet 112 to the first circulation channel.

[0076] Specifically, if Figure 2 and Figure 3 As shown, the third interlayer 131 is located between the inner wall and the outer wall of the third section 13.

The cooling mechanism cools the reflux cooling liquid and then transports it to the third circulation channel from the third inlet 132.

[0077] In this embodiment, liquid cooling is used to simplify the structures of the first section 11 and the third section 13 and achieve a more uniform cooling effect.

[0078] In a specific embodiment, Figure 3As shown, a second inlet 122 and a second outlet 123 are provided on the outer wall of the second section 12, the second inlet 122 is connected to the second interlayer 121, and the second outlet 123 is connected to the second interlayer 121; specifically, the second interlayer 121 is located between the inner wall and the outer wall of the second section 12, which can be understood as a second circulation channel provided between the inner wall and the outer wall of the second section 12, the second circulation channel being used to accommodate oil; a second inlet 122 and a second outlet 123 are provided on the outer wall of the second section 12, the second inlet 122 is connected to the second circulation channel, and the second outlet 123 is connected to the second circulation channel; the second inlet 122 and the second outlet 123 are used for an external heating mechanism, the heating mechanism transports the heated oil into the second circulation channel through the second inlet 122, and the heated oil circulates in the second circulation channel and flows out from the second outlet 123 to the heating mechanism, the heating mechanism heats the refluxed oil and then transports it from the second inlet 122 to the second circulation channel. By heating the oil, the structure of the second section 12 can be simplified and the cooling effect can be more uniform.

[0079] In another specific embodiment, Figure 2 As shown, a heating assembly 124 is provided within the second interlayer 121. Specifically, the second interlayer 121 is located between the inner and outer walls of the second section 12. This can be understood as a receiving groove defined between the inner and outer walls of the second section 12. The heating assembly 124 is disposed within the receiving groove to heat the second receiving cavity 12a. In this embodiment, the heating efficiency is higher. The heating assembly 124 can be an electric heating rod, which provides greater temperature controllability and improves the quality of the mixed material fiberization.

[0081] In another specific embodiment, a second heat insulation layer 16 is provided between the second section 12 and the third section 13 .

[0082] In another specific embodiment, a first heat insulating layer 15 is provided between the first section 11 and the second section 12, and a second heat insulating layer 16 is provided between the second section 12 and the third section 13. This embodiment is taken as an example for description.

[0083] Specifically, if Figure 2 and Figure 3As shown, since the first section 11 cools the first accommodating cavity 11a and the second section 12 heats the second accommodating cavity 12a, in order to avoid the first section 11 and the second section 12 affecting each other, a first thermal insulation layer 15 is set between the first section 11 and the second section 12; since the third section 13 cools the third accommodating cavity 13a, in order to avoid the second section 12 and the third section 13 affecting each other, a second thermal insulation layer 16 is set between the second section 12 and the third section 13.

[0085] In an alternative embodiment, Figure 2 and Figure 3 As shown, along the axial direction of the first accommodating chamber 11a, the inner diameter of the first accommodating chamber 11a gradually increases from the end away from the second section 12 to the end close to the second section 12; specifically, the axial cross-section of the first accommodating chamber 11a is trapezoidal, that is, narrow at the top and wide at the bottom. This structure is conducive to the formation of a more uniform vortex of the mixed material in the first accommodating chamber 11a, thereby enhancing the dispersion effect of the mixed material; it can also guide the mixed material to form a stable circulating flow in the first accommodating chamber 11a, so as to reduce the retention of the mixed material at the end of the first accommodating chamber 11a away from the second accommodating chamber 12a, thereby facilitating the mixed material to enter the second accommodating chamber 12a.
