[0002] A solid-state battery is a battery that uses solid electrodes and solid electrolytes. At present, the negative electrode materials of solid-state batteries are mainly divided into three categories: graphite negative electrode, silicon-based negative electrode and metal lithium negative electrode. Silicon (Si) is regarded as the most promising negative electrode material in all-solid-state lithium-ion batteries because of its theoretical capacity of up to 4200 mAh / g, which is much higher than the capacity of graphite negative electrode, and its abundant silicon resources and low cost. Especially in sulfide all-solid-state lithium-ion batteries, the application of silicon-based negative electrodes is expected to greatly increase the energy density of batteries and promote technological innovation in the fields of electric vehicles and energy storage systems. In the preparation of solid-state battery negative electrode materials, the silicon-based materials and solid electrolytes need to be fully dispersed and contacted, so an efficient stirring device for stirring the negative electrode materials is required.

[0022] In this embodiment: the solid-state battery negative electrode material stirring device is mainly divided into three parts: a mixing bin 1, a stirring mechanism 2 and a cleaning mechanism 3. When the device is in use, a variety of solid-state battery materials are first added to the mixing bin 1 through the feed pipe 102. Then the stirring motor 201 and the rotating motor 109 are started. When the stirring motor 201 drives the cantilever 208 to rotate, the stirring fan 214 will also revolve relative to the walking gear ring 211 while revolving relative to the stirring gear 212. When the stirring motor 201 drives the linkage rod 202 to rotate, at this time, under the drive of the linkage bevel gear 204, the driven bevel gear 206 drives the driven cylinder 205 and the stirring arm 207 to rotate in opposite directions. After the raw materials in the mixing bin 1 are stirred, they are temporarily stored in the storage bin 113 through the reflux pump 115. When unloading is required, the discharge pump 117 and the cleaning motor 120 are started, and the cleaning motor 120 drives the flip cylinder 301 and the cleaning arc plate 306 to reciprocate and clean the inner wall of the discharge pipe 116.

[0023] See attached Figure 2 -Attached Figure 5A meshing cavity 105 is also provided at the top of the annular cavity 103, and a rotating gear ring 107 movably arranged in the meshing cavity 105 is installed on the top of the scraping ring 106; a mounting plate 108 is provided on the outer wall of the mixing chamber 1, and a rotating motor 109 is installed on the mounting plate 108, and a driving gear 110 meshing with the rotating gear ring 107 is installed at the output end of the rotating motor 109.

[0024] In this embodiment, during the mixing operation, due to the presence of a small amount of dead angle in the mixing mechanism 2, some raw materials will adhere to the inner wall of the mixing bin 1. When the rotary motor 109 drives the scraping ring 106 to rotate, the raw materials on the inner wall of the scraping ring 106 at the slots 104 will fall down or accumulate on the inner wall between the slots 104 under the scraping of the slots 104, and finally the raw materials between the slots 104 will slide down under the action of the accumulated gravity.

[0025] See attached Figure 1 and attached Figure 7 A feed pipe 102 is provided on the top cover 101, a reflux pipe 114 connected to the storage bin 113 is installed at the bottom of the mixing bin 1, and a reflux pump 115 is installed on the reflux pipe 114; a discharge pump 117 connected to the discharge pipe 116 is installed in the storage bin 113, and a control panel 122 is also provided on the outer wall of the mixing bin 1.

[0026] In this embodiment, after the raw materials in the mixing bin 1 are mixed, in order not to delay the subsequent mixing operation, they are temporarily stored in the storage bin 113 through the reflux pump 115. In order to control the operation of the equipment, a control panel 122 structure is designed.

[0027] See attached Figure 2 -Attached Figure 4 A through linkage chamber 111 is provided at the bottom of the mixing bin 1 , and the driven cylinder 205 is movably installed in the linkage chamber 111 . A bearing 123 movably connected to the driven cylinder 205 is also installed on the inner wall of the linkage chamber 111 .

[0028] In this embodiment: During the stirring operation, in order to further improve the stirring effect, two sets of stirring structures with opposite stirring directions are designed. When the stirring motor 201 drives the linkage rod 202 to rotate clockwise, the active bevel gear 203 at the bottom will also rotate clockwise. At this time, driven by the linkage bevel gear 204, the driven bevel gear 206 drives the driven cylinder 205 and the stirring arm 207 to rotate counterclockwise. In order to ensure that the driven cylinder 205 can rotate freely relative to the linkage chamber 111, a bearing 123 structure is designed.

[0029] See attached Figure 5 -Attached Figure 6A plurality of cantilevers 208 are also provided on the outer wall of the linkage rod 202, and a coaxial upper linkage gear 209 and a lower linkage gear 210 are movably installed in the middle of the cantilever 208; the upper linkage gear 209 and the lower linkage gear 210 are respectively located on both sides of the cantilever 208, and a traveling gear ring 211 meshing with the upper linkage gear 209 is fixedly provided at the bottom of the top cover 101; a stirring gear 212 meshing with the lower linkage gear 210 is movably installed at the end of the cantilever 208, and a swing arm 213 is fixedly provided at the bottom of the stirring gear 212, and a stirring fan 214 which is not coaxial with the stirring gear 212 is fixedly provided at the bottom of the swing arm 213.

[0030] In this embodiment, when the stirring motor 201 drives the cantilever 208 to rotate, the upper linkage gear 209 will revolve relative to the travel gear ring 211 and drive the lower linkage gear 210 to rotate. Since the stirring fan 214 and the stirring gear 212 are not coaxially arranged, the stirring fan 214 will revolve relative to the travel gear ring 211 while revolving relative to the stirring gear 212.

[0031] See attached Figure 1 and attached Figure 7 -Attached Figure 8 A turning gear 303 is arranged on the top of the turning cylinder 301, and an installation cavity 118 cooperating with the turning cylinder 301 is also provided inside the discharge pipe 116; a limiting groove 119 is provided on the inner wall of the installation cavity 118, and a limiting convex ring 302 cooperating with the limiting groove 119 is provided on the outer wall of the turning cylinder 301; a cleaning motor 120 is installed at the bottom of the storage bin 113, and a driving gear 121 meshing with the turning gear 303 is installed at the output end of the cleaning motor 120.

[0032] In this embodiment, in order to ensure that the turning cylinder 301 is movably arranged in the installation cavity 118, a mutually matching limiting groove 119 and limiting convex ring 302 structure is designed. In order to drive the turning cylinder 301 to rotate automatically, a cleaning motor 120 structure is designed.

[0033] See attached Fig. 9 -Attached Fig.10 A plurality of telescopic cavities 304 are provided on the inner wall of the flip cylinder 301, symmetrical restoration cavities 305 are provided on both sides of the telescopic cavities 304, a slider 308 slidably arranged in the telescopic cavities 304 is fixedly arranged on the outer wall of the cleaning arc plate 306, and a symmetrical restoration spring 309 is also connected to the outer wall of the cleaning arc plate 306, and the end of the restoration spring 309 is connected to the inner wall of the restoration cavity 305.

[0034] In this embodiment: when the deformed gear ring 315 rotates counterclockwise, the cleaning arc plate 306 moves along the telescopic cavity 304 to the middle of the flip cylinder 301 under the pressure of the arc-shaped convex seat 317, and the inner diameter of the cleaning arc plate 306 is reduced and separated from the discharge tube 116, so as to prevent the cleaning arc plate 306 from adhering to the inner wall thereof for a long time and causing damage to the equipment. When the deformed gear ring 315 rotates clockwise, the arc-shaped convex seat 317 is separated from the cleaning arc plate 306, and the cleaning arc plate 306 moves along the telescopic cavity 304 to the outside of the flip cylinder 301 under the drive of the return spring 309, and the inner diameter of the cleaning arc plate 306 is enlarged and abuts against the inner wall of the discharge tube 116.

[0035] See attached Figure 8 and attached Fig.10 A scraping portion 307 is provided on the side of the cleaning arc plate 306 .

[0036] In this embodiment, in order to further improve the cleaning effect and avoid raw material residue, an inclined scraping portion 307 is designed.

[0038] In this embodiment: in order to ensure that the deformable gear ring 315 rotates freely relative to the rotating chamber 310, a track 311 and a ring track chamber 316 structure that cooperate with each other are designed. In order to drive the deformable gear rings 315 on the upper and lower sides to rotate synchronously, so as to further adjust the inner diameter of the cleaning arc plate 306, a dual-axis motor 313 structure is designed. In the initial state, that is, when the cleaning arc plate 306 abuts against the inner wall of the flip cylinder 301 and the inner diameter is the largest, the right angle side of the arc-shaped protrusion 317 abuts against the outer wall of the cleaning arc plate 306. This design can further improve the stability of the cleaning arc plate 306 during rotation and scraping.

[0039] Working principle of the present invention: When the device is in use, a variety of solid-state battery materials are first added to the mixing bin 1 through the feed pipe 102. Then the stirring motor 201 and the rotating motor 109 are started. When the stirring motor 201 drives the cantilever 208 to rotate, the stirring fan 214 will also orbit relative to the traveling gear ring 211 while revolving relative to the stirring gear 212. When the stirring motor 201 drives the linkage rod 202 to rotate, at this time, under the drive of the linkage bevel gear 204, the driven bevel gear 206 drives the driven cylinder 205 and the stirring arm 207 to rotate in opposite directions. After the raw materials in the mixing bin 1 are stirred, they are temporarily stored in the storage bin 113 through the reflux pump 115. When unloading is required, the discharge pump 117 and the cleaning motor 120 are started, and the cleaning motor 120 drives the flip cylinder 301 and the cleaning arc plate 306 to reciprocate and clean the inner wall of the discharge pipe 116.
