[0002] As the dry process for lithium battery pulping becomes increasingly popular, the demand for lithium battery production capacity is also growing. The existing functions of mixers, the mainstream equipment for lithium battery pulping, can no longer fully meet the needs of the lithium battery market. The dry process for lithium batteries involves first dry-mixing the main material powder, auxiliary material powder, and glue in a high-viscosity mixer, then diluting and mixing to achieve a kneaded and dispersed slurry. The maximum process viscosity can reach hundreds of thousands of mP·s, placing very high demands on pulping equipment.

[0060] The second stirring part 12 is provided on one side of the first stirring part 11. When the kneading device is in use, the first stirring part 11 rotates around a first rotation axis 13, and the second stirring part 12 rotates around a second rotation axis 14. The first rotation axis 13 and the second rotation axis 14 are parallel to each other.

[0061] The first stirring portion 11 includes a first threaded belt 111 and a second threaded belt 112 .

[0062] The second thread belt 112 and the first thread belt 111 are centrally symmetrically arranged about the first rotation axis 13. The second thread belt 112 is fixedly connected to the first thread belt 111. The structure of the first thread belt 111 is the same as that of the second thread belt 112.

[0063] The second stirring portion 12 includes a third thread belt 121 and a fourth thread belt 122 .

[0064] The fourth thread belt 122 and the third thread belt 121 are centrally symmetrically arranged about the second rotation axis 14. The third thread belt 121 is fixedly connected to the fourth thread belt 122. The structure of the third thread belt 121 is the same as that of the fourth thread belt 122.

[0065] The pitch of the first thread band 111 is smaller than the pitch of the third thread band 121 .

[0066] Specifically, the pitch of the first thread band 111 is equal to the pitch of the third thread band 121 is equal to two to one, the cross-sectional shape of the first thread band 111 is the same as the cross-sectional shape of the second thread band 112, and the cross-sectional shape of the third thread band 121 is the same as the cross-sectional shape of the fourth thread band 122;.

[0067] In this embodiment, the first stirring part 11 and the second stirring part 12 rotate synchronously, and the rotation speed of the first stirring part 11 is twice the rotation speed of the second stirring part 12, and the rotation direction of the first stirring part 11 is opposite to the rotation direction of the second stirring part 12, so that the first thread belt 111 rotates and engages with the third thread belt 121 at twice the rotation speed, further improving the stirring efficiency of the slurry; at the same time, the second thread belt 112 rotates and engages with the fourth thread belt 122 at twice the rotation speed, further improving the stirring efficiency of the slurry; further, in the process of stirring the slurry by the first stirring part 11 and the second stirring part 12, engagement and disengagement are continuously generated to improve the stirring efficiency of the slurry.

[0068] like Figure 2 and Figure 3 As shown, in one embodiment of the present application, the kneading device further includes a first connecting member 15 and a second connecting member 16 .

[0069] The first connecting member 15 is disposed between the first threaded belt 111 and the second threaded belt 112. The first threaded belt 111 and the second threaded belt 112 are connected by the first connecting member 15 to fix the relative position between the first threaded belt 111 and the second threaded belt 112.

[0070] The second connecting member 16 is disposed between the third threaded belt 121 and the fourth threaded belt 122. The third threaded belt 121 and the fourth threaded belt 122 are connected by the second connecting member 16 to fix the relative position between the third threaded belt 121 and the fourth threaded belt 122.

[0071] Specifically, the first connecting member 15 is provided with an inclined first extrusion surface 151 and an inclined second extrusion surface 152. The first extrusion surface 151 is provided on one side of the first connecting member 15, and the second extrusion surface 152 is provided on the other side of the first connecting member 15. The first extrusion surface 151 and the second extrusion surface 152 form a V shape.

[0072] The second connecting member 16 is provided with an inclined third extrusion surface 161 and an inclined fourth extrusion surface 162. The third extrusion surface 161 is provided on one side of the second connecting member 16, and the fourth extrusion surface 162 is provided on the other side of the second connecting member 16. The third extrusion surface 161 and the fourth extrusion surface 162 form a V shape.

[0073] In this embodiment, when the first connecting member 15 rotates, the synchronized first extrusion surface 151 and the second extrusion surface 152 will rotate synchronously, and then the inclined first extrusion surface 151 and the inclined second extrusion surface 152 will be used to continuously extrude the slurry to form a stirring vortex; when the second connecting member 16 rotates, the synchronized third extrusion surface 161 and the fourth extrusion surface 162 will rotate synchronously, and then the inclined third extrusion surface 161 and the inclined fourth extrusion surface 162 will be used to continuously extrude the slurry to form a stirring vortex; there is an intersection between the vortex generated by the first connecting member 15 and the vortex generated by the second connecting member 16, so as to further improve the stirring efficiency of the slurry.

[0074] like Figure 2 As shown, in one embodiment of the present application, the first connecting member 15 is disposed between the first threaded belt 111 and the second threaded belt 112, with one end of the first connecting member 15 connected to any point on the first threaded belt 111, and the other end of the first connecting member 15 connected to any point on the second threaded belt 112. The second connecting member 16 is disposed between the third threaded belt 121 and the fourth threaded belt 122, with one end of the second connecting member 16 connected to any point on the third threaded belt 121, and the other end of the second connecting member 16 connected to any point on the fourth threaded belt 122.

[0075] Specifically, the connection position of the first connecting member 15 can be set according to the characteristics of the slurry being stirred, including density and viscosity, etc., so as to adjust the strength of the entire first stirring part 11, thereby adjusting the size of the gap between the first threaded belt 111 and the second threaded belt 112. It can also save materials because the positions where the first connecting member 15 and the second connecting member 16 are set in this embodiment use less material than if they are set at the end.

[0076] In this embodiment, the first connecting member 15 is not only used to fix the relative position between the first threaded belt 111 and the second threaded belt 112, but also used to stir the slurry; the second connecting member 16 is not only used to fix the relative position between the third threaded belt 121 and the fourth threaded belt 122, but also used to stir the slurry.

[0077] like Figure 4 and Figure 5 As shown, in one embodiment of the present application, the kneading device further includes a first support member 17 and a second support member 18 .

[0078] The first support member 17 is disposed at one end of the first threaded belt 111. The first threaded belt 111 is fixedly connected to the first support member 17. The second threaded belt 112 is fixedly connected to the first support member 17 to fix the relative position between the first threaded belt 111 and the second threaded belt 112.

[0079] The second support member 18 is disposed at one end of the third threaded belt 121. The third threaded belt 121 is fixedly connected to the second support member 18. The fourth threaded belt 122 is fixedly connected to the second support member 18 to fix the relative position between the third threaded belt 121 and the fourth threaded belt 122.

[0080] Specifically, the first support member 17 is arranged at the end of the first threaded belt 111, and the end surface of the first support member 17 close to the first threaded belt 111 is fixedly connected to the first threaded belt 111, and the end surface of the first support member 17 close to the first threaded belt 111 is also fixedly connected to the second threaded belt 112.

[0081] An inclined first extrusion surface 151 and an inclined second extrusion surface 152 are provided on a side of the first support member 17 away from the first threaded belt 111 , and the first extrusion surface 151 and the second extrusion surface 152 are arranged in a V shape.

[0082] The second support member 18 is arranged at the end of the third thread belt 121, and the end surface of the second support member 18 close to the third thread belt 121 is fixedly connected to the third thread belt 121, and the end surface of the second support member 18 close to the third thread belt 121 is also fixedly connected to the fourth thread belt 122.

[0083] An inclined third extrusion surface 161 and an inclined fourth extrusion surface 162 are provided on a side of the second support member 18 away from the third threaded belt 121 , and the third extrusion surface 161 and the fourth extrusion surface 162 are arranged in a V shape.

[0084] like Figure 4As shown, in one embodiment of the present application, the length of the first thread belt 111 along the first rotation axis 13 is equal to the length of the third thread belt 121 along the second rotation axis 14 .

[0085] Specifically, the length of the first threaded belt 111 along the first rotation axis 13, the length of the second threaded belt 112 along the first rotation axis 13, the length of the third threaded belt 121 along the second rotation axis 14, and the length of the fourth threaded belt 122 along the second rotation axis 14 are all equal, and the end of the first threaded belt 111 close to the first support member 17, the end of the second threaded belt 112 close to the first support member 17, the end of the third threaded belt 121 close to the second support member 18, and the end of the fourth threaded belt 122 close to the second support member 18 are located in the same plane.

[0086] In this embodiment, by setting the length of the first thread belt 111 along the vertical direction, the length of the second thread belt 112 along the vertical direction, the length of the third thread belt 121 along the vertical direction, and the length of the fourth thread belt 122 along the vertical direction to be the same, the first thread belt 111 and the third thread belt 121 are meshed, and the second thread belt 112 and the fourth thread belt 122 are meshed multiple times when the first stirring part 11 and the second stirring part 12 rotate synchronously, thereby improving the stirring efficiency of the slurry.

[0087] like Figure 6 As shown, in one embodiment of the present application, when the first thread belt 111 rotates around the first rotation axis 13 , one end of the first thread belt 111 forms a first cutting annular surface 19 , and the other end of the first thread belt 111 forms a second cutting annular surface 20 .

[0088] The first cutting annular surface 19 and the second cutting annular surface 20 are parallel to each other. The first rotation axis 13 is perpendicular to the first cutting annular surface 19 .

[0089] Specifically, the plane where the first cutting annular surface 19 is located is parallel to the plane where the second cutting annular surface 20 is located. The first cutting annular surface 19 is annular, and the center of the first cutting annular surface 19 is located on the first rotation axis 13. The second cutting annular surface 20 is annular, and the center of the second cutting annular surface 20 is located on the first rotation axis 13.

[0090] When the second threaded belt 112 rotates around the first rotation axis 13 , the annular surface formed at one end of the second threaded belt 112 coincides with the first cutting annular surface 19 , and the annular surface formed at the other end of the second threaded belt 112 coincides with the second cutting annular surface 20 .

[0091] In this embodiment, the relative position relationship between the first cutting annular surface 19 and the second cutting annular surface 20 is limited to improve the force stability of the two ends of the first thread belt 111 when stirring the slurry and improve the force stability of the two ends of the second thread belt 112 when stirring the slurry.

[0092] like Figure 6 As shown, in one embodiment of the present application, when the third thread belt 121 rotates around the second rotation axis 14 , one end of the third thread belt 121 forms a third cutting annular surface 21 , and the other end of the third thread belt 121 forms a fourth cutting annular surface 22 .

[0093] The third cutting annular surface 21 and the fourth cutting annular surface 22 are parallel to each other. The second rotation axis 14 is perpendicular to the third cutting annular surface 21 .

[0094] Specifically, the plane where the third cutting annular surface 21 is located is parallel to the plane where the fourth cutting annular surface 22 is located. The third cutting annular surface 21 is annular, and the center of the third cutting annular surface 21 is located on the second rotation axis 14. The fourth cutting annular surface 22 is annular, and the center of the fourth cutting annular surface 22 is located on the first rotation axis 13.

[0095] When the fourth threaded belt 122 rotates around the second rotation axis 14 , the annular surface formed at one end of the fourth threaded belt 122 coincides with the third cutting annular surface 21 , and the annular surface formed at the other end of the fourth threaded belt 122 coincides with the fourth cutting annular surface 22 .

[0096] In this embodiment, the relative position relationship between the third cutting annular surface 21 and the fourth cutting annular surface 22 is limited to improve the force stability of the two ends of the third thread belt 121 when stirring the slurry and improve the force stability of the two ends of the fourth thread belt 122 when stirring the slurry.

[0097] like Figure 7 As shown, in one embodiment of the present application, the first cutting annular surface 19 is coplanar with the third cutting annular surface 21 , and the second cutting annular surface 20 is coplanar with the fourth cutting annular surface 24 .

[0098] Specifically, the outer circle line of the first cutting annular surface 19 is tangent to the inner circle line of the third cutting annular surface 21 , and the outer circle line of the second cutting annular surface 20 is tangent to the inner circle line of the fourth cutting annular surface 24 .

[0099] In this embodiment, during the engagement of the first thread band 111 and the third thread band 121, the outer circle line of the first cutting annular surface 19 will be tangent to the inner circle line of the third cutting annular surface 21; during the engagement of the second thread band 112 and the fourth thread band 122, the outer circle line of the second cutting annular surface 20 will be tangent to the inner circle line of the fourth cutting annular surface 24.

[0100] like Figure 7 As shown, in one embodiment of the present application, the diameter of the first cutting annular surface 19 is equal to the diameter of the third cutting annular surface 21. The inner diameter of the first cutting annular surface 19 is equal to the inner diameter of the third cutting annular surface 21.

[0101] Specifically, the size of the first cutting annular surface 19 is the same as the size of the third cutting annular surface 21, and the first cutting annular surface 19 and the third cutting annular surface 21 have an intersecting portion on the same plane; the size of the second cutting annular surface 20 is the same as the size of the fourth cutting annular surface 24, and the second cutting annular surface 20 and the fourth cutting annular surface 24 have an intersecting portion on the same plane.

[0102] like Figures 8 to 11 As shown, in one embodiment of the present application, the spiral direction of the first thread belt 111 is opposite to the spiral direction of the third thread belt 121.

[0103] Specifically, the spiral direction of the first thread belt 111 is the same as the spiral direction of the second thread belt 112 ; the spiral direction of the third thread belt 121 is the same as the spiral direction of the fourth thread belt 122 .

[0104] In this embodiment, by setting the rotation direction of the first stirring part 11 to be opposite to the rotation direction of the second stirring part 12, and the rotation speed of the first stirring part 11 is twice the rotation speed of the second stirring part 12, the first thread band 111 and the third thread band 121 are meshed with each other under the condition of a pitch of two to one, and the second thread band 112 and the fourth thread band 122 are meshed with each other under the condition of a pitch of two to one.

[0105] Specifically, the first thread band 111 includes a first thread surface 111a, a second thread surface 111b and a third thread surface 111c. The first thread surface 111a, the second thread surface 111b and the third thread surface 111c are sequentially surrounded by a solid body to constitute the first thread band 111. The first thread surface 111a and the second thread surface 111b form a first spiral line 23 at the connection between the first thread surface 111a and the third thread surface 111c, the second spiral line 24 is formed at the connection between the first thread surface 111a and the third thread surface 111c, and the third spiral line 25 is formed at the connection between the second thread surface 111b and the third thread surface 111c.

[0106] The second thread band 112 includes a fourth thread surface 112a, a fifth thread surface 112b and a sixth thread surface 112c. The fourth thread surface 112a, the fifth thread surface 112b and the sixth thread surface 112c are sequentially surrounded by a solid body to constitute the second thread band 112. The fourth thread surface 112a and the fifth thread surface 112b are connected to form a fourth spiral line 26, the fourth thread surface 112a and the sixth thread surface 112c are connected to form a fifth spiral line 27, and the fifth thread surface 112b and the sixth thread surface 112c are connected to form a sixth spiral line 28.

[0107] The third thread band 121 includes a seventh thread surface 121a, an eighth thread surface 121b and a ninth thread surface 121c. The seventh thread surface 121a, the eighth thread surface 121b and the ninth thread surface 121c are sequentially surrounded by a solid body to constitute the third thread band 121. The seventh thread surface 121a and the eighth thread surface 121b are connected to form a seventh helical line 29, the seventh thread surface 121a and the ninth thread surface 121c are connected to form an eighth helical line 30, and the eighth thread surface 121b and the ninth thread surface 121c are connected to form a ninth helical line 31.

[0108] The fourth thread band 122 includes a tenth thread surface 122a, an eleventh thread surface 122b and a twelfth thread surface 122c. The tenth thread surface 122a, the eleventh thread surface 122b and the twelfth thread surface 122c are sequentially surrounded by a solid body to constitute the fourth thread band 122. The connection between the tenth thread surface 122a and the eleventh thread surface 122b forms a tenth spiral line 32, the connection between the tenth thread surface 122a and the twelfth thread surface 122c forms an eleventh spiral line 33, and the connection between the eleventh thread surface 122b and the twelfth thread surface 122c forms a twelfth spiral line 34.

[0109] In this embodiment, when the first stirring part 11 and the second stirring part 12 rotate synchronously, the first spiral line 23 will engage with the eighth thread surface 121b to stir the slurry; the fourth spiral line 26 will engage with the eleventh thread surface 122b to stir the slurry; at the same time, the first thread band 111, the second thread band 121, the third thread band 121 and the fourth thread band 122 are all solid structures surrounded by multiple thread surfaces in sequence, which not only improves the structural strength but also improves the stirring efficiency.
