Description

Technical Field

[0001] This invention relates to the field of graphite anode material processing technology, and in particular to a graphite anode material cooling device. Background Technology

[0002] In the industrial production of graphite anode materials, after processes such as high-temperature calcination and mechanical crushing, the material forms a high-temperature powder. This powder needs to undergo strict cooling treatment to bring its temperature down to the range required by subsequent processing techniques before it can proceed to the next production step. If the cooling process is not standardized or sufficient, it will not only affect the crystal structure and electrochemical performance of the graphite anode material, but may also lead to problems such as material agglomeration and equipment wear during subsequent processing, thereby affecting the quality stability of the final product.

[0003] Currently, there are many types of cooling devices for graphite anode material powder in the industry, but they still have many common defects in practical applications, making it difficult to meet the needs of large-scale, high-quality production. Existing cooling devices generally suffer from low cooling efficiency, mainly because the powder material is difficult to disperse uniformly after entering the device, easily forming local agglomerates. This results in insufficient contact between the material and the cooling medium, and some materials cannot be effectively cooled. At the same time, most cooling devices have a relatively simple cooling structure design with limited cooling area, failing to achieve graded and continuous cooling of the material, further limiting the improvement of cooling efficiency.

[0004] In addition, the drive system design of some existing cooling devices is complex, and problems such as jamming and poor synchronization are prone to occur during operation, which affects the continuity and stability of unloading. At the same time, some devices lack reasonable guidance and buffering design for the material during the falling process. The material falls too fast and the contact time with the cooling structure is insufficient, resulting in poor cooling effect and difficulty in meeting the production requirements of high-specification graphite anode materials.

[0005] Therefore, developing a device that can overcome the shortcomings of the existing technology and achieve efficient, uniform, and sufficient cooling of graphite anode material powder has become an urgent technical problem to be solved in the current field of graphite anode material processing. Summary of the Invention

[0006] To address the technical problems existing in the background art, the present invention proposes a cooling device for graphite anode materials.

[0007] The present invention proposes a cooling device for graphite anode materials, comprising: Cooling chamber: It is a cylindrical structure with a feed inlet at the top and a discharge outlet at the bottom, and a water-cooled chamber inside. The water-cooled chamber is equipped with a partition that divides it into a cold water chamber and a hot water chamber. The water-cooled chamber adopts a double-layer structure design with an inner wall and an outer wall. The cold water chamber is located close to the inner wall of the cooling chamber, and the hot water chamber is located on the outer wall side of the cooling chamber. The cooling medium is introduced into the cold water chamber through the inlet pipe, and the warm water after heat exchange is discharged from the hot water chamber through the outlet pipe.

[0008] Cooling structure: Multiple layers are spaced apart along the axial direction of the cooling chamber. Each layer includes several cooling components. The cooling components in each layer are evenly distributed circumferentially, and the upper and lower cooling components are staggered. The lower cooling components correspond to the gap positions of the upper cooling components to achieve layered reception of powder. The cooling components are provided with a spiral heat exchange channel inside. The water inlet of the spiral heat exchange channel is connected to the cold water chamber, and its water outlet is connected to the hot water chamber to achieve circulating heat exchange of the cooling medium. Dispersion mechanism: Located inside the cooling chamber, below the feed inlet, it disperses the powder conveyed by the feed inlet and throws it to the supporting cooling structure, which can achieve uniform dispersion of powder and ensure subsequent cooling effect. Drive mechanism: Used to drive the rotation of the cooling structure to achieve unloading and transfer of powder.

[0009] Preferably, the cooling component is a cylindrical roller.

[0010] Preferably, the cooling component has a flat paddle-shaped structure, and the spiral water channel inside the cooling component is adapted to the cross-sectional profile of the cooling component, so that the inner wall of the spiral water channel fits into the inner wall of the cooling component.

[0011] Preferably, the dispersing mechanism includes a guide cone, a turntable, a screw, a telescopic rod, and a fixed straight pipe. The guide cone is fixedly installed inside the cooling chamber to guide the feed to the turntable. The turntable is rotatably connected to the middle of the fixed straight tube via a bearing. The fixed straight tube is located vertically inside the cooling chamber, and its axis coincides with the axis of the cooling chamber. The bottom of the fixed straight tube is fixedly connected to the inner wall of the cooling chamber via a connector. The screw and telescopic rod are both housed inside the fixed straight tube to prevent the transmission components from contacting the powder and to prevent jamming. The screw is threadedly connected to the center of the turntable. When the screw moves downward and disengages from the turntable, the turntable rotates at high speed due to inertia, evenly throwing the powder onto the supporting cooling structure to achieve uniform dispersion.

[0012] Preferably, the drive mechanism includes a double-sided gear ring, a bevel gear, and a drive gear; Each cooling component of the load-bearing cooling structure of each layer has a rotating shaft that penetrates the side wall of the cooling chamber, and the bevel gear is fixedly connected to the end of the rotating shaft that extends out of the side wall of the cooling chamber; The number of double-sided toothed rings corresponds to the number of layers of the cooling structure. Each double-sided toothed ring is rotatably connected to the outer wall of the cooling chamber through a bearing, and each double-sided toothed ring meshes with all the bevel gears of the corresponding layer of the cooling structure. Each double-sided toothed ring has its other side meshing with a drive gear, which is driven by a drive element.

[0013] Preferably, when a single driving component is used, the single driving component drives each driving gear to rotate synchronously through a vertical transmission shaft and gear transmission, thereby driving all double-sided gear rings, bevel gears and cooling components to rotate synchronously, realizing the synchronous rotation of all load-bearing cooling structures.

[0014] Preferably, the top surface of the turntable has multiple sets of partition plates distributed in the central area. The partition plates are evenly spaced along the circumference of the turntable to separate and guide the powder on the turntable, thereby improving the uniformity and intensity of the powder ejection.

[0015] Preferably, the top of the cooling chamber is provided with multiple sets of inert gas nozzles, which are used to spray cooling inert gas into the cooling chamber to assist in the cooling of the powder.

[0016] Preferably, the outlet of the cooling chamber is connected to an elevator, and the outlet end of the elevator is connected to the inlet of the cooling chamber, so that the powder that is not completely cooled can be sent back into the cooling chamber for secondary cooling, thereby realizing the cyclic cooling of the powder.

[0017] Preferably, a sealing assembly is provided at the point where the rotating shaft passes through the side wall of the cooling chamber and the partition of the water-cooled chamber. The sealing assembly includes a sealing sleeve and a sealing ring, which are used to seal the gap between the rotating shaft and the partition and the side wall of the cooling chamber to prevent the cooling medium from leaking and powder from entering the water-cooled chamber.

[0018] The graphite anode material cooling device proposed in this invention has the following beneficial effects:

[0019] 1. The powder enters in a stream at the feed inlet, and the guide cone achieves the first-stage central diversion to avoid agglomeration; the turntable and partition plate achieve the second-stage centrifugal dispersion, dispersing the powder to each cooling component and inner wall area, ensuring that every piece of powder can enter the cooling area.

[0020] 2. The multi-layer staggered cooling structure significantly expands the powder contact area. The staggered cooling components in the upper and lower layers divide a stream of powder into multiple parts. Each layer supports a portion of the powder, while the unsupported powder leaks to the next layer, achieving graded cooling and greatly improving the overall contact area and cooling efficiency.

[0021] 3. The cold water chamber is positioned close to the inner wall of the cooling chamber. Some powder is thrown onto the inner wall and then slides down along the inner wall, receiving cooling simultaneously. This structure allows part of the powder to contact the cooling components and part to contact the inner wall of the cooling chamber, achieving dual-system synergistic cooling of the cooling components and the inner wall, significantly improving the overall cooling capacity.

[0022] 4. The rotating shaft extends the powder path and enhances the cooling efficiency. The rotating shaft of each cooling component forms an obstruction in the powder's falling path, changing the powder's falling trajectory and causing it to be disturbed multiple times during its descent along the inner wall. This prolongs the contact time between the powder and the cooling structure, ensuring sufficient and uniform cooling.

[0023] 5. The spiral heat exchange channel improves the heat exchange efficiency of a single cooling component. The internal spiral water channel of the cooling component increases the contact length between the cooling medium and the cooling component, enhances the cooling capacity of a single cooling component, and ensures that each layer of powder can be effectively cooled.

[0024] 6. A single drive unit synchronously drives all cooling components, reducing control costs. A single drive unit drives all layers of double-sided gear rings, bevel gears and cooling components through gear transmission to achieve synchronous rotation, ensuring both uniform unloading and consistent surface refresh of cooling components, thus reducing equipment control difficulty and manufacturing costs.

[0025] 7. The sealed structure ensures stable and leak-free operation. The screw and telescopic rod of the dispersion mechanism are completely housed in the fixed straight pipe to prevent powder from getting stuck. A sealing component is installed between the rotating shaft and the partition and bin wall to prevent the cooling medium from leaking and ensure stable operation of the device.

[0026] 8. Circulating cooling ensures stable finished product quality. Powder that is not fully cooled is returned by an elevator and re-enters the cooling chamber, achieving multiple rounds of thorough cooling to ensure stable product quality.

[0027] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1

[0045] like Figures 1-9The graphite anode material cooling device shown includes a cooling chamber 1, a supporting cooling structure 2, a dispersion mechanism 3, and a driving mechanism 4. The specific structure and connection relationship of each component are as follows: The cooling chamber 1 has a cylindrical structure with an inlet 101 at the top and an outlet 102 at the bottom, and a water-cooled chamber 103 inside. The water-cooled chamber 103 adopts a double-layer structure design: the cold water chamber 1031 is set close to the inner wall of the cooling chamber 1, and the hot water chamber 1032 is located on the outer wall side of the cooling chamber 1. The two are separated by a partition 1033. The cold water chamber 1031 is supplied with cooling medium through an inlet pipe 1034. In this embodiment, the cooling medium is cooling water. The hot water chamber 1032 discharges the warm water after heat exchange through an outlet pipe 1035 to realize the circulation and heat exchange of the cooling medium. The cooling chamber 1 is equipped with a fixed straight pipe 305. The vertical axis of the fixed straight pipe 305 is located inside the cooling chamber 1, and its axis coincides with the axis of the cooling chamber 1. The bottom of the fixed straight pipe 305 is fixedly connected to the inner wall of the cooling chamber 1 through a connector to ensure that the fixed straight pipe 305 is stably set.

[0046] The cooling structure 2 is arranged in multiple layers (10 layers in this embodiment) along the axial direction of the cooling chamber 1. Each layer includes several cooling components 201 (22 components per layer in this embodiment). The cooling components 201 in each layer are evenly distributed circumferentially, and the upper and lower cooling components 201 are staggered. The lower cooling component 201 corresponds to the gap position of the upper cooling component 201, so as to realize the layered reception of powder. The cooling component 201 is a cylindrical roller. The cooling component 201 has a spiral heat exchange channel 2011 inside. The water inlet 2012 of the spiral heat exchange channel 2011 is connected to the cold water chamber 1031, and its water outlet 2013 is connected to the hot water chamber 1032, so as to realize the circulation heat exchange of the cooling medium, increase the heat exchange area, and improve the cooling efficiency.

[0047] The dispersing mechanism 3 is located below the feed inlet 101 and includes a guide cone 301, a turntable 302, a screw 303, a telescopic rod 304, and a fixed straight tube 305.

[0048] The guide cone 301, with its tip pointing upwards and directly facing the feed inlet 101, diverts the stream of powder injected from the feed inlet 101 from the center outwards, preventing the powder from directly agglomerating and falling into the central area of ​​the turntable.

[0049] The turntable 302 is rotatably connected to the middle of the fixed straight tube 305 via a bearing. The screw 303 and the telescopic rod 304 are both housed inside the fixed straight tube 305 to avoid contact with the powder and causing jamming.

[0050] The screw 303 is threadedly connected to the center of the turntable 302. When the screw 303 moves downward and disengages from the turntable 302, the turntable 302 rotates at high speed due to inertia, using centrifugal force to throw the powder towards the edge area.

[0051] Multiple sets of partition plates 3021 are evenly arranged on the top surface of the turntable 302. The partition plates 3021 are distributed circumferentially and have a two-stage effect on the powder: first, they separate the powder into multiple strands and improve the dispersion; second, they generate radial thrust on the powder and enhance the powder throwing intensity, so that the powder can be evenly thrown onto the cooling components or the inner wall of the cooling chamber.

[0052] The drive mechanism 4 includes a double-sided gear ring 401, a bevel gear 402, a drive gear 403, and a vertical transmission shaft 404.

[0053] Each cooling component 201 is connected to a rotating shaft 202 that passes through the side wall of the cooling chamber 1, and a bevel gear 402 is fixed to the protruding end of the rotating shaft 202.

[0054] The double-sided gear ring 401 meshes with all the bevel gears 402 of the corresponding layer, and the other side of the double-sided gear ring 401 meshes with the drive gear 403, which is driven by a drive component.

[0055] When a single drive unit is used, the single drive unit drives all drive gears 403 to rotate synchronously through the vertical drive shaft 404 and gear transmission, thereby driving all double-sided gear rings 401, bevel gears 402 and cooling components 201 to rotate synchronously.

[0056] The rotation of cooling component 201 serves two purposes: 1. Unloading: Shake the cooled powder off the surface of the cooling component to the next layer or the discharge port; 2. Refresh the surface of cooling components: Remove the original powder layer from the surface of the cooling components, keep them clean to receive the next batch of powder, and ensure that each batch is cooled on a clean surface.

[0057] The top of the cooling chamber 1 is equipped with multiple sets of inert gas nozzles 5. The inert gas nozzles 5 are used to spray cooling inert gas into the cooling chamber 1. In this embodiment, nitrogen is used to assist in powder cooling and further improve the cooling effect. An elevator is connected to the outlet 102 of the cooling chamber 1. The outlet end of the elevator is connected to the inlet 101 of the cooling chamber 1, which can send the powder that has not been completely cooled back into the cooling chamber 1 for secondary cooling, so as to realize the circulating cooling of the powder and ensure that the powder temperature reaches the standard. A sealing assembly is provided at the point where the rotating shaft 202 passes through the side wall of the cooling chamber 1 and the partition 1033 of the water-cooled chamber 103. The sealing assembly includes a sealing sleeve and a sealing ring, which are used to seal the gap between the rotating shaft 202 and the partition 1033 and the side wall of the cooling chamber 1 to prevent the cooling medium from leaking and the powder from entering the water-cooled chamber 103.

[0058] The working process of this embodiment is as follows: High-temperature graphite anode material powder is fed into the cooling chamber 1 through the feed port 101. It is first guided by the cone 301 to flow from the center to the surrounding area and falls smoothly onto the turntable 302. The telescopic rod 304 drives the screw 303 to move downward. When the screw 303 disengages from the turntable 302, the turntable 302 rotates at high speed due to inertia. Under the separation and guidance of the partition plate 3021, the powder is evenly thrown onto the cooling component 201 of the upper-layer cooling structure 2 and the inner wall of the cooling chamber 1. Part of the powder falls onto the cooling component 201 and is cooled by the internal spiral heat exchange channel; the other part is thrown to the inner wall of the cooling chamber, slides down the inner wall, and is cooled by the cold water chamber 1031 at the same time. As the powder falls layer by layer, it is blocked by the rotating shafts 202 of each layer, which changes the falling path and prolongs the contact time with the cooling structure to ensure sufficient cooling. After cooling is completed, the drive unit drives all drive gears 403 to rotate synchronously through the vertical drive shaft 404 and gear transmission. The drive gears 403 drive the double-sided gear ring 401 to rotate, and the double-sided gear ring 401 drives the bevel gear 402 and the rotating shaft 202 to rotate, thereby driving all cooling components 201 to rotate synchronously, realizing the unloading and transfer of powder; the powder falls down layer by layer along the upper and lower staggered cooling components 201. The cooling medium enters the cold water chamber 1031 through the water inlet pipe 1034, and then exchanges heat with the powder through the spiral heat exchange channel 2011 inside the cooling component 201. The warm water after heat exchange enters the hot water chamber 1032 and is discharged through the water outlet pipe 1035, thus realizing the circulation heat exchange of the cooling medium. Meanwhile, the inert gas nozzle 5 sprays cooling inert gas into the cooling chamber 1 to assist in powder cooling; the powder that is not completely cooled enters the elevator through the discharge port 102, and is sent back to the feed port 101 by the elevator, and enters the cooling chamber 1 again for secondary cooling until the powder temperature reaches the standard, and is finally discharged through the discharge port 102.

[0059] After the powder scattering operation is completed and the turntable 302 gradually stops rotating, the telescopic rod 304 drives the screw 303 to move upward and reconnect with the center of the turntable 302 via a threaded connection. Since the turntable 302 is rotatably connected to the fixed straight tube 305 through a bearing, it can rotate freely around the fixed straight tube 305. Therefore, when the screw 303 moves upward, the turntable 302 can automatically fine-tune the rotation angle to precisely match the thread of the screw 303, achieving a smooth connection and preparing for the next powder scattering operation. This connection method is consistent with the rotational adaptation structure principle of the bamboo dragonfly, relying on the rotatable characteristics to achieve automatic alignment and matching of the threads. Example 2

[0060] like Figure 10As shown, the difference between this embodiment and Embodiment 1 is that the cooling component 201 has a flat paddle-shaped structure, which can increase the bearing area for high-temperature powder. The spiral water channel inside the cooling component 201 is adapted to the cross-sectional profile of the cooling component 201, so that the inner wall of the spiral water channel fits the inner wall of the cooling component 201, further increasing the heat exchange area, improving the cooling efficiency, and adapting to the cooling requirements of different types of graphite anode materials. The remaining structure and working process are the same as in Embodiment 1, and will not be described again here.
