[0040] In this application, "multiple" means two or more (including two).

[0041] The development of new materials is advancing rapidly. In the process of processing powder materials, we often encounter the problem of using kilns (roller kilns, pusher kilns, etc.) to calcine the materials. After calcination, many materials often clump together after being poured out of the sagger, forming clumped materials. Therefore, coarse crushing must be carried out before subsequent fine crushing.

[0042] Taking the production of cathode materials for lithium batteries as an example, the production process requires mixing raw materials in a certain proportion, then loading them into a high-temperature saggar for high-temperature sintering, followed by crushing, sieving, demagnetizing, and packaging. Before high-temperature sintering, the materials in the saggar are cut into pieces to prevent large lumps of caking material from forming after sintering.

[0043] However, due to the characteristics of the materials and the changes in sintering conditions, even though the materials were cut into blocks before sintering, varying degrees of agglomeration still occurred after high-temperature sintering. Therefore, coarse crushing was necessary before fine crushing.

[0044] In existing technologies, roller mills or rotary mills are commonly used for coarse crushing. During the coarse crushing process, bridging may occur, causing caking materials to be unable to enter the crushing device, resulting in the accumulation of caking materials and blockage. This not only easily creates breakpoints in the production process, affecting processing efficiency, but also requires manual unblocking. There is a probability that foreign objects may be introduced into the crushing device, leading to abnormal product indicators and a decline in product quality.

[0045] Based on this, this application proposes a crushing device that uses a spinning assembly to spin the bridging material upstream of the feed inlet to improve the bridging phenomenon of the bridging material, reduce the probability of material blockage, and improve production efficiency. Moreover, it eliminates the need for manual material blockage clearing and also reduces the probability of foreign objects entering the crushing device, thereby improving product processing quality.

[0046] The following is for reference. Figures 1-4 Describes a crushing device 100 according to an embodiment of the present utility model.

[0047] like Figure 1 and Figure 2 As shown, this application provides a crushing device 100 for caking materials, including: a device body 10, a feed bin 20, and at least one spinning assembly 30.

[0048] The device body 10 is equipped with a crushing component 11 and has a feed inlet 121. The feed bin 20 is located above the device body 10, and the slab material is suitable to enter the device body 10 through the feed bin 20 and be crushed. The spinning component 30 is located in the feed bin 20 and has a spinning part 32. The spinning part 32 rotates perpendicular to the feeding direction a and is used to push the slab material in the feed bin 20 to the feed inlet 121.

[0049] The crushing component 11 inside the device body 10 can be a double-roll crushing structure or a rotary mill crushing structure. The device body 10 can include a housing 12, with a feed inlet 121 at one end and a discharge outlet at the other end. The crushing component 11 is disposed between the feed inlet 121 and the discharge outlet and is adapted to coarsely crush the caking material entering through the feed inlet 121 and discharge it through the discharge outlet.

[0050] For example, the crushing component 11 adopts a roller crushing structure. The crushing component 11 includes two rollers arranged opposite each other. The two rollers rotate towards each other, such as one rotating counterclockwise and the other rotating clockwise, to crush the caking material. A clamping structure, such as a clamping spring, can be provided between the housing 12 and the rollers. The gap between the two rollers can be adjusted by the clamping spring to adjust the particle size of the coarse crushing. After the gap is adjusted, the gap between the two rollers can remain stable to improve the reliability and stability of the coarse crushing.

[0051] However, when the volume of the caking material is large, and there are serious large lumps of caking material, the caking material may be suspended in the feed hopper 20 and unable to contact the rollers, resulting in bridging and blockage, which affects processing efficiency.

[0052] Furthermore, this application provides a spinning assembly 30 in the feed hopper 20. There can be one or more spinning assemblies 30. The spinning part 32 of the spinning assembly 30 can rotate in a direction perpendicular to the feeding direction a, so as to push the caking material located above the feed inlet 121 through the spinning part 32, assist the caking material to contact the roller, improve the processing phenomenon, and reduce the probability of material blockage.

[0053] It is understandable that by rotating the spinning part 32 inside the feed bin 20 and pushing the bridging material to the feed inlet 121 in the feeding direction a, the bridging material can be broken up during the pushing process to improve the bridging phenomenon. Through the pushing action, the amount of bridging material supplied to the roller can be more stable, so as to alleviate or even eliminate the accumulation of bridging material.

[0054] According to the embodiment of this application, the crushing device 100, by setting a spinning component 30 in the feed bin 20, crushes the large volume of caking material in the feed bin 20 and pushes the caking material to the feed inlet 121, which can improve the overhang phenomenon, avoid material blockage, improve crushing efficiency, eliminate the need for manual material blockage clearing, reduce the probability of foreign objects entering the feed bin 20, and prevent the caking material from being contaminated, thereby improving the coarse crushing effect and coarse crushing quality.

[0055] like Figure 3 As shown, according to some embodiments of this application, the spinning assembly 30 includes: a rotating shaft 31 and a plurality of spinning portions 32 disposed on the rotating shaft 31, the plurality of spinning portions 32 being spaced apart in the axial direction of the rotating shaft 31, and the rotating shaft 31 being rotatably disposed in the feed bin 20.

[0056] Specifically, the rotating shaft 31 is disposed inside the feed hopper 20, at least one end of the rotating shaft 31 passes through the feed hopper 20, and a bearing can be disposed between the rotating shaft 31 and the feed hopper 20 to reduce the resistance of the rotating shaft 31 to rotate relative to the feed hopper 20. Multiple spinning parts 32 can be spaced apart in the axial direction of the rotating shaft 31, that is, multiple spinning parts 32 can be spaced apart in the length direction of the feed hopper 20.

[0057] Therefore, by setting multiple spinning sections 32 on the rotating shaft 31, and the multiple spinning sections 32 can be spaced apart along the length of the feed bin 20, the large volume of caking material can be crushed and the caking material as a whole can be pushed and conveyed toward the feed inlet 121 in different areas and positions of the feed bin 20 through the multiple spinning sections 32. This allows the caking material in each area inside the feed bin 20 to be pushed and supplied to the feed inlet 121 by the corresponding spinning section 32, thereby improving the clearance, avoiding material accumulation, improving processing efficiency, improving crushing quality, and reducing the probability of caking material being contaminated.

[0058] like Figure 3 and Figure 4 As shown, according to some embodiments of this application, the spinning part 32 includes a connecting rod 321 and a crushing head 322. The connecting rod 321 is connected to the rotating shaft 31, and the crushing head 322 is disposed at the free end of the connecting rod 321. At least a portion of the cross-sectional area of ​​the crushing head 322 is larger than the cross-sectional area of ​​the connecting rod 321.

[0059] Specifically, a sleeve is provided at one end of the connecting rod 321, which is fitted onto the rotating shaft 31. A crushing head 322 is provided at the other end of the connecting rod 321 so that the crushing head 322 can rotate synchronously with the rotating shaft 31. At least part of the cross-sectional area of ​​the crushing head 322 is larger than the cross-sectional area of ​​the connecting rod 321, which can increase the pushing area of ​​the crushing head 322, thereby improving the conveying efficiency of caking materials and improving the crushing effect of the crushing head 322 on large-volume caking materials, thereby improving bridging phenomenon and reducing the probability of material blockage.

[0060] Therefore, by setting a crushing head 322 with a cross-sectional area larger than that of the connecting rod 321, on the one hand, the crushing effect of the larger crushing head 322 is better and the pushing effect of the caking material is better. On the other hand, the smaller connecting rod 321 generates less rotational resistance in the area of ​​the connecting rod 321 during the spinning process, and the overall spinning assembly 30 has higher working stability and reliability.

[0061] like Figure 3 As shown, according to some embodiments of this application, the orthographic projection profile of the crushing head 322 on the axial direction of the rotating shaft 31 is arc-shaped.

[0062] Specifically, the crushing head 322 is arc-shaped, and when the crushing head 322 is rotated to be perpendicular to the feeding direction a, the arc surface of the orthographic projection of the crushing head 322 is concave towards the feed inlet 121, so that the arc-shaped crushing head 322 can carry and push more slab material to the feed inlet 121, thereby improving the pushing efficiency, increasing the feeding speed, and improving the production efficiency.

[0063] In this way, by setting the crushing head 322 with an arc-shaped cross-section on the axial direction of the rotating shaft 31, the effective area of ​​the crushing head 322 can be increased, so that the crushing head 322 can push more caking material to the feed inlet 121, thereby improving the crushing efficiency.

[0064] See Figure 4 As shown, according to some embodiments of this application, the cross-sectional area of ​​the crushing head 322 gradually decreases in the direction away from the connecting rod 321.

[0065] Therefore, the crushing head 322 is roughly plow-shaped. During the process of pushing and pressing the agglomerated material, the large volume of agglomerated material can be pushed to the end of the crushing head 322 under the pushing and guiding action of the arc surface. The end area with a smaller cross-sectional area can crush the large volume of agglomerated material, reducing the difficulty of crushing the large volume of agglomerated material. Moreover, the smaller cross-sectional area of ​​the end area results in higher pressure applied to the agglomerated material, and the crushing effect of the large volume of agglomerated material is better. This can effectively improve the pushing and crushing effect, effectively avoid the phenomenon of material accumulation, and improve the coarse crushing effect and coarse crushing efficiency.

[0066] Combination Figure 1 and Figure 2 As shown, according to some embodiments of this application, there are multiple spinning components 30, and the multiple spinning components 30 are arranged sequentially in the feeding direction a.

[0067] Specifically, the feeding direction a can be the height direction, and multiple spinning components 30 are arranged sequentially in the height direction. By setting multiple spinning components 30, the crushing and pressing effect of the caking material can be further improved, thereby improving the coarse crushing effect of the crushing device 100 on the caking material.

[0068] For example, there are two spinning components 30, which are arranged sequentially in the height direction, with one spinning component 30 being higher than the other spinning component 30.

[0069] According to some embodiments of this application, the shafts 31 of adjacent spinning assemblies 30 are spaced apart in the width direction of the feed inlet 121.

[0070] Therefore, in the length direction of the feed inlet 121, multiple spinning parts 32 of each spinning assembly 30 are spaced apart, and in the width direction of the feed inlet 121, multiple spinning assemblies 30 are spaced apart, which can make the distribution of spinning parts 32 in the length and width directions of the feed inlet 121 more uniform, so that the spinning assembly 30 has a better crushing effect on large-volume caking materials and a better pushing effect on caking materials.

[0071] According to some embodiments of this application, the spinning portions 32 of adjacent spinning assemblies 30 are staggered in the axial direction of the rotating shaft 31, and the rotation directions of adjacent spinning assemblies 30 are opposite.

[0072] Therefore, while improving the crushing and pressing effects, it can also reduce the probability of interference between adjacent spinning components 30, thereby improving the working stability and reliability of the spinning components 30.

[0073] According to some embodiments of this application, among the plurality of spinning assemblies 30, the size of the crushing head 322 of the spinning assembly 30 adjacent to the feed inlet 121 is smaller.

[0074] For example, there are three spinning components 30, which are arranged sequentially in the height direction. The three spinning components 30 are defined as a first spinning component 30, a second spinning component 30, and a third spinning component 30 arranged sequentially in the direction away from the feed inlet 121. The crushing head 322 of the third spinning component 30 is the smallest, the crushing head 322 of the second spinning component 30 is the second largest, and the crushing head 322 of the third spinning component 30 is the largest.

[0075] Therefore, by using multiple crushing heads 322 for gradient crushing, the crushing effect of large-volume caking materials can be further improved.

[0076] According to some embodiments of this application, the crushing device 100 further includes at least one driving part 40, and the driving part 40 is poweredly connected to the crushing component 11 and the spinning component 30 to drive the crushing component 11 and the spinning component 30 to rotate.

[0077] Specifically, there can be one or more drive units 40. When there is only one drive unit 40, the crushing assembly 11 and the spinning assembly 30 can be driven by multiple sets of drive components respectively. There can also be multiple drive units 40. Each crushing assembly 11 and the spinning assembly 30 is provided with a corresponding drive unit 40 so that the crushing assembly 11 is driven by the drive unit 40 to perform coarse crushing, and the multiple spinning assemblies 30 are used to perform pushing before coarse crushing and crushing of large-volume caking materials, thereby improving the crushing effect.

[0078] It should be noted that the drive unit 40 can be configured as a drive motor.
