Description

Crushing and shaping device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on August 25, 2023, with application number 202322308025.5 and application name “Crushing and Shaping Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of negative electrode material preparation, and in particular to a crushing and shaping device. Background Art

[0003] Graphite is an allotrope of carbon, a gray-black, opaque solid with stable chemical properties, corrosion resistance, and low reactivity with acids and alkalis. Natural graphite comes from graphite deposits, but it can also be made from materials such as petroleum coke and asphalt coke through a series of processing steps to produce artificial graphite. Graphite burns in oxygen to produce carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It is used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in nuclear reactors. It is also used in the manufacture of crucibles, electrodes, brushes, dry cell batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, and pen refills.

[0004] Graphite is the main material for lithium battery negative electrodes. Before making batteries, it needs to be processed through processes such as crushing, shaping, coating, and carbonization. Among them, the crushing and shaping processes put forward strict requirements on the graphite's tap density, specific surface area, sphericity and other indicators. Currently, the most common graphite crushing and spheroidization processes are mainly based on mechanical crushing and shaping, and the use of other forms of crushing and spheroidization equipment is rarely reported.

[0005] In the existing technology, when processing graphite, the entire set of equipment in some factories consists of more than ten airflow vortex micro-powder machines. The production line is very long, the area occupied is huge, and the energy consumption of using more than ten devices in series is very high. Some factories will use 2-5 fine crushers in series to crush the graphite and 3-20 shaping machines in series to shape the graphite. In the process of crushing and shaping, electric heating is used to heat the chamber, resulting in high energy consumption, long production line and large area occupied in this production line. There is also a horizontal three-roller crushing and shaping unit. The whole main machine is equipped with three drive motors, and each motor drives each crushing and shaping chamber arranged in parallel. Although it simplifies the process and reduces the area occupied, there are still problems of excessive energy consumption and low electrical production capacity.

The feed port 24 and the discharge port 25 are respectively connected to the accommodating chamber 23. The crushing mechanism 3 is accommodated in the accommodating chamber 23, and the crushing mechanism 3 has a feed end 3a and a discharge end 3b.

[0059] In one embodiment, the housing 2 includes a first portion 21 and a second portion 22 . The first portion 21 and the second portion 22 are detachably connected to form an accommodating cavity 23 , which facilitates maintenance and replacement of components in the accommodating cavity 23 .

[0060] In one embodiment, the first portion 21 and the second portion 22 are detachably connected by bolts. In other embodiments, the first portion 21 and the second portion 22 may also be connected by snap fasteners or other means.

[0061] In one embodiment, the feeding hopper 6 uses a screw feeding method to feed materials. It can be understood that in other embodiments, other methods can also be used to feed materials.

[0062] In one embodiment, the crushing and shaping device further includes a first support member 7 , which is disposed on the base 1 , and the shell 2 is disposed on the first support member 7 , and the first support member 7 is used to support the shell 2 .

[0063] In one embodiment, a plurality of crushing mechanisms 3 are provided, and the plurality of crushing mechanisms 3 are distributed along the first direction, so that the accommodating chamber 23 is divided into a plurality of crushing and shaping chambers that are interconnected along the first direction, and the driving mechanism 4 is connected to each crushing mechanism 3. A single driving mechanism 4 can simultaneously drive the plurality of crushing mechanisms 3 to work together, thereby simplifying the production line, reducing the floor space, increasing the electrical capacity, reducing energy consumption, and reducing production costs.

[0064] Referring to Figures 1, 4, 5, 6, and 7, Figure 4 is a schematic diagram of the structure of the rotating member of the crushing and shaping device provided in an embodiment of the present application, Figure 5 is a schematic diagram of the structure of the side cross-section of the rotating member of the crushing and shaping device provided in an embodiment of the present application, Figure 6 is a schematic diagram of the structure of the connection between the rotating member and the hammer blade of the crushing and shaping device provided in an embodiment of the present application, and Figure 7 is a schematic diagram of the structure of the side cross-section of the connection between the rotating member and the hammer blade of the crushing and shaping device provided in an embodiment of the present application. The drive mechanism 4 includes a motor 41, a main shaft 42, and a coupling 43. The first portion 21 of the housing 2 has first through holes at both ends, and the second portion 22 has second through holes at both ends. The positions of the first through holes correspond to the positions of the second through holes, and the main shaft 42 is rotatably inserted into the first through hole and the second through hole, respectively. The size of the first through hole and the size of the second through hole can be the same or different.

[0065] The motor 41 is disposed on the base 1 and is connected to the main shaft 42 via a coupling 43. The pulverizing mechanism 3 includes a rotating member 31 and a pulverizing member 30. The pulverizing member 30 includes a hammer blade 32, a tooth plate 33, and a plurality of guide members 34. The rotating member 31 includes a fixed portion 310 and a mounting portion 311. The fixed portion 310 is sleeved on the main shaft 42. A plurality of mounting portions 311 are provided, and the plurality of mounting portions 311 are spaced apart on the fixed portion 310 along the circumference of the fixed portion 310. A plurality of hammer blades 32 are provided, and each hammer blade 32 is connected to a respective mounting portion 311. The tooth plate 33 is disposed on the inner wall of the housing 2, and is disposed correspondingly to the hammer blades 32. A spacing is provided between the tooth plate 33 and the hammer blades 32 along the radial direction of the rotating member 31. The spacing is the shortest distance between the outer surface of the tooth plate 33 and the outer surface of the hammer blade 32. In one embodiment, the spacing between the tooth plate 33 and the hammer blade 32 is equal to facilitate installation design.

[0066] In other embodiments, the spacing between the tooth plate 33 and the hammer knife 32 is not equal, for example, it is set to decrease step by step, so that the material can be crushed and shaped step by step.

[0067] A plurality of guide members 34 are respectively arranged on the inner wall of the shell 2, and each guide member 34 is respectively located between two adjacent tooth plates 33, for separating each crushing and shaping chamber, and guiding the material in the first crushing and shaping chamber 12 to the hammer knife 32 of the second crushing and shaping chamber 13, and guiding the material in the second crushing and shaping chamber 13 to the hammer knife 32 of the third crushing and shaping chamber 14, and so on.

[0068] In one embodiment, the motor 41 is controlled by variable frequency speed regulation, which saves energy, reduces the number of starts and stops of the motor 41 , and prolongs the service life of the motor 41 .

[0069] In one embodiment, the distance between the outer surface of the main shaft 42 and the inner surface of the first through hole is in the range of 4 mm to 10 mm, and the distance between the outer surface of the main shaft 42 and the inner surface of the second through hole is in the range of 4 mm to 10 mm. The main shaft 42 has a certain distance from the first through hole and the second through hole respectively, which ensures that the shell 2 will not be affected when the main shaft 42 rotates, and the distance range is 4 mm to 10 mm, which ensures that the material will not flow out of the first through hole and the second through hole due to the first through hole and the second through hole being too large.

[0070] In one embodiment, six mounting portions 311 are provided. It is understandable that in other embodiments, four, eight, ten, twelve, etc. mounting portions 311 may be provided.

[0071] In one embodiment, the motor 41 and the main shaft 42 are connected via a coupling 43. It is understood that in other embodiments, the motor 41 and the main shaft 42 may also be connected via other means, such as belt drive.

[0072] In one embodiment, the ratio of the power of the motor 41 to the inner diameter of the tooth plate 33 is in the range of 0.05-0.3, and the ratio of the number of crushing and shaping chambers to the power of the motor 41 is in the range of 0.04-0.2, ensuring the compatibility of the motor 41 and the crushing and shaping device.

[0073] Continuing with Figure 1 , the crushing and shaping device further includes a fan 10, a bearing seat 11, a bearing, a second support member 8, and a third support member 9. The fan 10 is sleeved on the main shaft 42 and disposed within the accommodating chamber 23 and located on the side of the housing 2 where the discharge port 25 is provided. A guide member 34 is disposed between the fan 10 and a toothed plate 33 adjacent to the fan 10. The guide member 34 is used to direct the material in the front crushing and shaping chamber to the fan 10. The fan 10 is used to cooperate with the negative pressure generated by the external blower to eject the crushed material from the housing 2 through the discharge port 25. The second support member 8 is disposed on the base 1 and located at the end of the housing 2 where the feed port 24 is provided. The third support member 9 is disposed on the base 1 and located at the end of the housing 2 where the discharge port 25 is provided. Two bearing seats 11 are provided, one on each of the second support member 8 and the other on each of the third support members 9. Two bearings are provided, each bearing being movably disposed in each bearing seat 11. The two ends of the main shaft 42 are connected to the two bearings. The bearing is used to support the main shaft 42 to reduce the friction coefficient of the main shaft 42 during rotation, so that the main shaft 42 rotates more smoothly and reduces energy consumption.

[0074] Referring to Figures 1 and 8, Figure 8 is a schematic cross-sectional view of the guide member of the crushing and shaping device provided in an embodiment of the present application. The guide member 34 comprises a first surface 340, a second surface 341, and a guide bevel 342. The first surface 340 and the second surface 341 are disposed opposite each other. The first surface 340 is located on the side of the guide bevel 342 closer to the feed port 24, and the second surface 341 is located on the side of the guide bevel 342 closer to the discharge port 25. In a first direction, the projection of the first surface 340 completely falls within the projection of the second surface 341. The tooth plate 33 comprises a first contact surface and a second contact surface. The first contact surface is located on the side of the tooth plate 33 closer to the discharge port, and the second contact surface is located on the side of the tooth plate 33 closer to the feed port. The projection of the first surface 340 in the first direction completely falls within the first contact surface. The shortness of the first surface 340 facilitates the passage of the material through the guide bevel 342 of the guide member 34 into the next crushing and shaping chamber. The projection of the second contact surface in the first direction completely falls within the second surface 341. The second surface 341 is longer to prevent material entering the crushing and shaping chamber from passing directly into the next crushing and shaping chamber without being crushed. The angle θ between the guide slope 342 and the plane of the first surface 340 is in the range of 20° to 45°. Specifically, θ can be 20°, 25°, 30°, 35°, 40°, or 45°. This ensures that the material can be directed to the hammer blades 32 of the next crushing and shaping chamber without creating excessive resistance to the material flow.

[0075] Referring to Figures 9 and 10, Figure 9 is a schematic diagram of the structure of the tooth plate of the crushing and shaping device provided in an embodiment of the present application, and Figure 10 is a schematic diagram of the structure of another embodiment of the tooth plate of the crushing and shaping device provided in an embodiment of the present application. In one specific embodiment, the teeth of the tooth plate 33 are square in shape. The square's right angles can better crush the material when in contact with it, thereby improving work efficiency.

[0076] In another specific embodiment, the tooth shape of the tooth plate 33 is arc-shaped. The arc-shaped tooth shape has strong load-bearing capacity and bending resistance, which reduces the risk of damage to the tooth plate 33 caused by collision between the material and the tooth plate 33, thereby increasing the service life of the tooth plate 33.

[0077] In one embodiment, the guide member 34 and the tooth plate 33 are split into two halves at the center and are installed in the first portion 21 of the housing 2 and the second portion 22 of the housing 2 respectively.

[0078] Referring to Figure 11 , which is a schematic diagram of the structure of the tooth plates and guide members of the crushing and shaping device provided in an embodiment of the present application, the tooth plates 33 and guide members 34 are installed sequentially from the feed port 24 end of the housing 2 , such that adjacent tooth plates 33 are connected by the guide members 34 .

[0079] In a specific application scenario, the main shaft 42 is driven to rotate by the motor 41, and material is added to the feeding hopper 6. After the material enters the first crushing and shaping chamber 12 through the feed hopper 5, it is subjected to the interaction of the hammer knife 32 and the tooth plate 33 in the first crushing and shaping chamber 12, which collides, shears and grinds the material, thereby achieving the first crushing and shaping of the material. Then, under the action of the negative pressure generated by the external fan, the material enters the second crushing and shaping chamber 13 through the guide member 34 to continue crushing and shaping, and so on, until it reaches the last crushing and shaping chamber and completes the last crushing and shaping. The negative pressure generated by the fan 10 and the external fan jointly acts to make the material enter the grading mechanism through the discharge port 25. The grading mechanism sorts the graphite, and the qualified size material enters the collecting mechanism through the grading mechanism. The unqualified size material is sent back to the feed hopper 5 through the grading mechanism for further crushing and shaping.
