Technical Field

[0001] This application relates to the field of mixing technology, and in particular to kneading equipment. Background Technology

[0002] With the increasing prevalence of dry lithium-ion battery pulping processes, the demand for lithium-ion battery production capacity is also growing. As the mainstream equipment for lithium-ion battery pulping, the existing functions of mixers can no longer fully meet the needs of the lithium-ion battery market. The dry lithium-ion battery process involves first dry-mixing the main material powder, auxiliary material powder, and adhesive in a mixer at high viscosity, then diluting and mixing them to achieve kneading and dispersion of the slurry—a rapid pulping process. Its highest process viscosity can reach hundreds of thousands of mP·s, thus placing extremely high demands on the pulping equipment.

[0003] The market demands mixers with longer continuous operating time, longer maintenance cycles, and lower failure rates when using dry processes; however, existing mixer products cannot meet the market's needs for continuous, trouble-free operation in a vacuum under high resistance and high-intensity operating conditions, while ensuring high safety and environmental friendliness. Summary of the Invention

[0019] One end of the second connector is connected to any point on the third threaded band, and the other end of the second connector is connected to any point on the fourth threaded band.

[0020] Furthermore, it also includes:

The third threaded band is fixedly connected to the second support member, and the fourth threaded band is fixedly connected to the second support member to fix the relative position between the third threaded band and the fourth threaded band.

[0023] Furthermore, the length of the first threaded band along the first rotation axis is equal to the length of the third threaded band along the second rotation axis.

[0024] Furthermore, when the first threaded band rotates around the first rotation axis, one end of the first threaded band forms a first cutting annular surface, and the other end of the first threaded band forms a second cutting annular surface;

[0025] The first cutting ring surface and the second cutting ring surface are parallel to each other, and the first rotation axis is perpendicular to the first cutting ring surface.

[0026] Furthermore, when the third threaded band rotates around the second rotation axis, one end of the third threaded band forms a third cutting annular surface, and the other end of the third threaded band forms a fourth cutting annular surface;

[0030] Furthermore, the helical direction of the first threaded band is opposite to that of the third threaded band.

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0059] like Figure 1 As shown, in one embodiment of this application, the kneading device includes a first stirring section 11 and a second stirring section 12.

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

[0061] The first stirring part 11 includes a first threaded band 111 and a second threaded band 112.

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

[0063] The second stirring section 12 includes a third threaded band 121 and a fourth threaded band 122.

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

[0065] The pitch of the first threaded band 111 is less than the pitch of the third threaded band 121.

[0066] Specifically, the pitch of the first threaded band 111 is 2:1 compared to the pitch of the third threaded band 121. The cross-sectional shape of the first threaded band 111 is the same as that of the second threaded band 112, and the cross-sectional shape of the third threaded band 121 is the same as that of the fourth threaded band 122.

[0067] In this embodiment, the first stirring part 11 and the second stirring part 12 rotate synchronously, with the rotation speed of the first stirring part 11 being twice that of the second stirring part 12, and the rotation direction of the first stirring part 11 being opposite to that of the second stirring part 12. This causes the first threaded belt 111 to engage with the third threaded belt 121 at twice the rotation speed, further improving the stirring efficiency of the slurry. At the same time, the second threaded belt 112 also engages with the fourth threaded belt 122 at twice the rotation speed, further improving the stirring efficiency of the slurry. Furthermore, the continuous engagement and disengagement of the first stirring part 11 and the second stirring part 12 during the stirring of the slurry further enhances the stirring efficiency of the slurry.

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

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

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

[0071] Specifically, the first connector 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 connector 15, and the second extrusion surface 152 is provided on the other side of the first connector 15. The first extrusion surface 151 and the second extrusion surface 152 form a V-shape.

[0072] The second connector 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 connector 16, and the fourth extrusion surface 162 is provided on the other side of the second connector 16. The third extrusion surface 161 and the fourth extrusion surface 162 form a V-shape.

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

[0074] like Figure 2 As shown, in one embodiment of this application, a first connector 15 is disposed between a first threaded band 111 and a second threaded band 112. One end of the first connector 15 is connected to any point on the first threaded band 111, and the other end of the first connector 15 is connected to any point on the second threaded band 112. A second connector 16 is disposed between a third threaded band 121 and a fourth threaded band 122. One end of the second connector 16 is connected to any point on the third threaded band 121, and the other end of the second connector 16 is connected to any point on the fourth threaded band 122.

[0075] Specifically, the connection position of the first connector 15 can be set according to the characteristics of the slurry being stirred, including density and viscosity, thereby adjusting the strength of the entire first stirring part 11 and adjusting the size of the gap between the first threaded band 111 and the second threaded band 112. This can also save materials, because in this embodiment, the positions where the first connector 15 and the second connector 16 are set require less material than those where they are set at the ends.

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

[0077] like Figure 4 and Figure 5 As shown, in one embodiment of this 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 band 111. The first threaded band 111 is fixedly connected to the first support member 17. The second threaded band 112 is fixedly connected to the first support member 17 to fix the relative position between the first threaded band 111 and the second threaded band 112.

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

[0080] Specifically, the first support member 17 is disposed at the end of the first threaded band 111, and the end face of the first support member 17 near the first threaded band 111 is fixedly connected to the first threaded band 111. The end face of the first support member 17 near the first threaded band 111 is also fixedly connected to the second threaded band 112.

[0081] The first support member 17 has an inclined first extrusion surface 151 and an inclined second extrusion surface 152 on the side away from the first threaded band 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 disposed at the end of the third threaded band 121, and the end face of the second support member 18 near the third threaded band 121 is fixedly connected to the third threaded band 121. The end face of the second support member 18 near the third threaded band 121 is also fixedly connected to the fourth threaded band 122.

[0083] The second support member 18 has an inclined third extrusion surface 161 and an inclined fourth extrusion surface 162 on the side away from the third threaded band 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 this application, the length of the first threaded band 111 along the direction of the first rotation axis 13 is equal to the length of the third threaded band 121 along the direction of the second rotation axis 14.

[0085] Specifically, the lengths of the first threaded band 111 along the first rotation axis 13, the second threaded band 112 along the first rotation axis 13, the third threaded band 121 along the second rotation axis 14, and the fourth threaded band 122 along the second rotation axis 14 are all equal, and the ends of the first threaded band 111 near the first support member 17, the ends of the second threaded band 112 near the first support member 17, the ends of the third threaded band 121 near the second support member 18, and the ends of the fourth threaded band 122 near the second support member 18 are located in the same plane.

[0086] In this embodiment, by setting the vertical lengths of the first threaded band 111, the second threaded band 112, the third threaded band 121, and the fourth threaded band 122 to be the same, the first threaded band 111 and the third threaded band 121, as well as the second threaded band 112 and the fourth threaded band 122, can be engaged 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 this application, when the first threaded band 111 rotates about the first rotation axis 13, one end of the first threaded band 111 forms a first cutting annular surface 19, and the other end of the first threaded band 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 containing the first cutting ring surface 19 and the plane containing the second cutting ring surface 20 are parallel to each other. The first cutting ring surface 19 is annular, and the center of the first cutting ring surface 19 is located on the first rotation axis 13. The second cutting ring surface 20 is annular, and the center of the second cutting ring surface 20 is located on the first rotation axis 13.

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

[0091] In this embodiment, the relative positional relationship between the first cutting ring surface 19 and the second cutting ring surface 20 is used to improve the stress stability of the two ends of the first threaded band 111 when stirring the slurry and to improve the stress stability of the two ends of the second threaded band 112 when stirring the slurry.

[0092] like Figure 6 As shown, in one embodiment of this application, when the third threaded band 121 rotates about the second rotation axis 14, one end of the third threaded band 121 forms a third cutting annular surface 21. The other end of the third threaded band 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 containing the third cutting ring 21 is parallel to the plane containing the fourth cutting ring 22. The third cutting ring 21 is annular, and its center is located on the second rotation axis 14. The fourth cutting ring 22 is annular, and its center is located on the first rotation axis 13.

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

[0096] In this embodiment, the relative positional relationship between the third cutting ring surface 21 and the fourth cutting ring surface 22 is used to improve the stress stability of the two ends of the third threaded band 121 when stirring the slurry and to improve the stress stability of the two ends of the fourth threaded band 122 when stirring the slurry.

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

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

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

[0100] like Figure 7 As shown, in one embodiment of this 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 ring surface 19 is the same as that of the third cutting ring surface 21, and the first cutting ring surface 19 and the third cutting ring surface 21 have an intersecting portion on the same plane; the size of the second cutting ring surface 20 is the same as that of the fourth cutting ring surface 24, and the second cutting ring surface 20 and the fourth cutting ring surface 24 have an intersecting portion on the same plane.

[0102] like Figures 8 to 11 As shown, in one embodiment of this application, the helical direction of the first threaded band 111 is opposite to the helical direction of the third threaded band 121.

[0103] Specifically, the helical direction of the first threaded band 111 is the same as that of the second threaded band 112; the helical direction of the third threaded band 121 is the same as that of the fourth threaded band 122.

[0104] In this embodiment, by setting the rotation direction of the first stirring part 11 to be opposite to that of the second stirring part 12, and setting the rotation speed of the first stirring part 11 to be twice that of the second stirring part 12, the first threaded band 111 and the third threaded band 121 are engaged in a meshing relationship under the condition of a pitch ratio of 2:1, and the second threaded band 112 and the fourth threaded band 122 are engaged in a meshing relationship under the condition of a pitch ratio of 2:1.

[0105] Specifically, the first threaded band 111 includes a first threaded surface 111a, a second threaded surface 111b, and a third threaded surface 111c. The solid formed by the first threaded surface 111a, the second threaded surface 111b, and the third threaded surface 111c constitutes the first threaded band 111. A first helix 23 is formed at the connection between the first threaded surface 111a and the second threaded surface 111b. A second helix 24 is formed at the connection between the first threaded surface 111a and the third threaded surface 111c. A third helix 25 is formed at the connection between the second threaded surface 111b and the third threaded surface 111c.

[0106] The second threaded band 112 includes a fourth threaded surface 112a, a fifth threaded surface 112b, and a sixth threaded surface 112c. The solid formed by the fourth threaded surface 112a, the fifth threaded surface 112b, and the sixth threaded surface 112c constitutes the second threaded band 112. A fourth helix 26 is formed at the junction of the fourth threaded surface 112a and the fifth threaded surface 112b. A fifth helix 27 is formed at the junction of the fourth threaded surface 112a and the sixth threaded surface 112c. A sixth helix 28 is formed at the junction of the fifth threaded surface 112b and the sixth threaded surface 112c.

[0107] The third threaded band 121 includes a seventh threaded surface 121a, an eighth threaded surface 121b, and a ninth threaded surface 121c. The entity formed by the seventh threaded surface 121a, the eighth threaded surface 121b, and the ninth threaded surface 121c in sequence constitutes the third threaded band 121. A seventh helix 29 is formed at the connection between the seventh threaded surface 121a and the eighth threaded surface 121b. An eighth helix 30 is formed at the connection between the seventh threaded surface 121a and the ninth threaded surface 121c. A ninth helix 31 is formed at the connection between the eighth threaded surface 121b and the ninth threaded surface 121c.

[0108] The fourth threaded band 122 includes a tenth threaded surface 122a, an eleventh threaded surface 122b, and a twelfth threaded surface 122c. The solid formed by the tenth threaded surface 122a, the eleventh threaded surface 122b, and the twelfth threaded surface 122c constitutes the fourth threaded band 122. The tenth helix 32 is formed at the connection between the tenth threaded surface 122a and the eleventh threaded surface 122b. The eleventh helix 33 is formed at the connection between the tenth threaded surface 122a and the twelfth threaded surface 122c. The twelfth helix 34 is formed at the connection between the eleventh threaded surface 122b and the twelfth threaded surface 122c.

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

[0110] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted.
