Description

Technical Field

[0001] This invention belongs to the technical field of battery anode material production equipment, specifically relating to a crucible powder loading and compaction device for battery graphite anode material production. Background Technology

[0002] In the production of lithium-ion battery anode materials, during the pre-carbonization process in a crucible tunnel kiln and the purification process in an Atchison graphitization crucible furnace, semi-finished graphite powder of the anode material needs to be filled into the crucible before loading into the furnace. During filling, the graphite powder has numerous gaps between particles, is loose, and has a low density, which hinders heat transfer between the graphite particles. Therefore, the filled graphite powder needs to be thoroughly compacted. Compacted graphite exhibits better thermal uniformity, helping to ensure that the graphite undergoes a consistent heat treatment process, thus obtaining a uniform product. Otherwise, loose areas may not reach the required temperature (insufficient graphitization), while dense areas may overheat (energy waste and raw material loss).

[0003] The traditional method involves manually filling the crucible with graphite raw material and then manually tamping the material. However, this method has several problems. The manual tamping method is limited by the strength of the person, resulting in a low compaction density. This leads to a small filling volume, high labor costs, material spillage and loss, excessive costs, low efficiency, inconvenient operation, and dust generation, which causes large-scale environmental pollution in the workshop. It is also difficult to collect the dust in an organized manner, and the serious material loss reduces the yield of finished products. Summary of the Invention

[0004] This application proposes a crucible powder filling and compaction device for the production of graphite anode materials for batteries, which can fill the crucible with graphite powder and compact the graphite powder, thereby improving the filling efficiency of graphite powder into the crucible.

[0005] To achieve the above objectives, the invention provides the following technical solution: A crucible powder loading and compaction device for producing graphite anode materials for batteries includes a filling section, a compaction section, and a recovery section. The filling section, compaction section, and recovery section are mounted and supported by a mounting frame. The filling section is located above the compaction section, and the recovery section is located below the compaction section. The filling section is provided with a filling cavity, and a first screen is provided at the bottom of the filling cavity. A feeding pipe is provided at the lower part of the first screen, and the feeding pipe is connected to a conveying pipe. The bottom end of the conveying pipe is connected to a distribution bin in the compaction section. A distribution pipe is provided at the bottom of the distribution bin, and the distribution pipe extends to the crucible. The crucible is placed on a vibration platform, and a vibration motor is provided in the vibration platform. A partition is provided below the vibration platform, and a first discharge hopper is provided below the partition. The first discharge hopper is located above the recovery section, and the first discharge hopper is connected to a second discharge hopper below it.

[0006] In one embodiment of this application, a pack-breaking knife is provided at the upper end of the first screen. The pack-breaking knife is composed of multiple blades, and the blades are arranged in a conical shape.

[0007] In one embodiment of this application, an observation window is provided on the sidewall of the packing cavity.

[0008] In one embodiment of this application, the feed tube disposed at the lower part of the first screen is made of flexible canvas.

[0009] In one embodiment of this application, a dust suction hood is provided between the feed pipe and the feed tube. The dust suction hood is connected to the first suction pipe through a second suction pipe. The first suction pipe is connected to a bag filter dust collector, which is disposed inside the packing section.

[0010] In one embodiment of this application, a first dust suction pipe is provided on one side of the packing chamber, and the first dust suction pipe is connected to the bag filter through a first air suction pipe.

[0011] In one embodiment of this application, the second suction pipe extends into the vibrating section, and the air inlet of the second suction pipe faces the opening of the crucible.

[0012] In one embodiment of this application, the material distribution bin, crucible, and vibration platform are arranged inside a dust collection compartment, and a roller shutter door is provided on one side of the dust collection compartment.

[0013] In one embodiment of this application, a vibrating screen is provided between the first hopper and the second hopper.

[0014] In one embodiment of this application, a stirring and crushing component is provided at the bottom of the material distribution bin.

[0015] In summary, the technical solution proposed in this application includes the following beneficial technical effects: This application places the crucible on a vibration platform, and the vibration platform is equipped with a vibration motor. The vibration motor drives the vibration platform, which in turn drives the crucible to vibrate. As graphite powder is added to the crucible, the graphite particles are in motion with the vibrating crucible, which reduces the static friction between the graphite particles. Under the action of gravity, the graphite particles will move and fill the gaps between the particles. That is, the vibration causes the graphite particles to be displaced and rearranged in the crucible, making the graphite particles more compact and improving the filling efficiency of graphite powder into the crucible.

Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0023] This embodiment provides a crucible powder loading and compaction device for the production of graphite anode materials for batteries. (See reference...) Figures 1-7 As shown, it includes a filling section 1, a compaction section 2, and a recovery section 3. The filling section 1, the compaction section 2, and the recovery section 3 are mounted on a support frame. The filling section 1 is located above the compaction section 2, and the recovery section 3 is located below the compaction section 2. The filling section 1 is provided with a filling cavity 11. A first screen 111 is provided at the bottom of the filling cavity 11. A feeding pipe 12 is provided at the lower part of the first screen 111. The feeding pipe 12 is connected to a conveying pipe 13. The bottom end of the conveying pipe 13 is connected to a distribution bin 21 in the compaction section 2. A distribution pipe 22 is provided at the bottom of the distribution bin 21. The distribution pipe 22 extends into the crucible 4. The crucible 4 is placed on a vibration platform 23. A vibration motor 231 is provided in the vibration platform 23. A partition is provided below the vibration platform 23. A first dropping hopper 31 is provided below the partition. The first dropping hopper 31 is located above the recovery section 3. The first dropping hopper 31 is connected to a second dropping hopper 32 below it.

[0024] In the above embodiment, the packing section 1, the compaction section 2, and the recovery section 3 are arranged vertically using a metal mounting frame. The packing section 1 is positioned above the compaction section 2, and the recovery section 3 is positioned below the compaction section 2. The packing section 1 contains a packing cavity 11 for pouring or adding graphite powder. For example, a movable lifting device is positioned above the packing cavity 11 to lift a ton bag containing graphite powder into the packing cavity 11. The graphite powder packaging is broken to allow the graphite powder to fall into the packing cavity 11. A first screen 111 is positioned at the bottom of the packing cavity 11 for preliminary screening and filtration of the graphite powder, which helps improve the uniformity of the graphite powder. Furthermore, a feeding pipe 12 is provided at the lower part of the first screen 111, and the feeding pipe 12 is connected to the conveying pipe 13. Graphite powder enters the conveying pipe 13 through the feeding pipe 12. The bottom end of the conveying pipe 13 is connected to the distribution bin 21 in the vibrating section 2, that is, graphite powder enters the distribution bin 21 in the vibrating section 2 through the conveying pipe 13. Multiple distribution pipes 22 are connected to the bottom of the distribution bin 21. A crucible 4 is placed below the distribution pipe 22, that is, the distribution pipe 22 is used to add graphite powder into the crucible 4. Optionally, a pneumatic butterfly valve is installed on each distribution pipe 22 to control the opening and closing of the distribution pipe 22. The outlet of the distribution pipe 22 extends into the opening of the crucible 4. Furthermore, the crucible 4 is placed on the vibration platform 23, and the vibration platform 23 is equipped with a vibration motor 231. The vibration motor 231 drives the vibration platform 23, which in turn drives the crucible 4 to vibrate. This causes the graphite particles to move along with the vibrating crucible 4 during the addition of graphite powder, reducing the static friction between the graphite particles. Under the influence of gravity, the graphite particles move and fill the gaps between them. In other words, the vibration causes the graphite particles to shift and rearrange within the crucible 4, resulting in a more compact arrangement of graphite particles. In addition, the graphite particles form tiny channels during their movement, allowing air to escape upwards and preventing voids in the graphite powder. Compared to simple compaction, the moving graphite particles have more freedom to accurately locate and fill the voids, achieving a more uniform and dense graphite powder. In addition, a partition is provided below the vibration platform 23, and a hole is provided on the partition. A first funnel is provided below the partition. When graphite powder is added to the crucible 4, the scattered graphite powder enters the discharge hopper in the recovery section 3 through the hole on the partition for recovery, which is beneficial to improving the utilization efficiency of graphite powder.

[0025] In one embodiment of this application, see reference Figure 5 As shown, the upper end of the first screen 111 is provided with a pack-breaking knife 112, which is composed of multiple blades and the blades are arranged in a conical shape.

[0026] In the above embodiment, the packing cutter 112 is used to cut open the outer packaging of the ton bag, i.e., graphite powder, which is hoisted into the filling cavity 11, so that the graphite powder flows out. Furthermore, the packing cutter 112 is composed of multiple blades, and the blades are arranged in a conical shape. When the ton bag comes into contact with the packing cutter 112, the conical blades collide and tear open the outer packaging. The edges of the cone can break the outer packaging from multiple angles and directions. Compared with using a single blade to break the outer packaging, the packing efficiency is higher. It can also avoid the situation where the packaging is cut open but the opening is not fully opened, saving the process of manual unpacking and improving the feeding efficiency. In addition, compared with manual opening, it reduces the process of workers coming into contact with powder and avoids the risk of dust inhalation and being cut by the blade.

[0027] In one embodiment of this application, see [reference] Figure 2 As shown, an observation window 113 is provided on the side wall of the packing cavity 11.

[0028] In the above embodiment, the observation window 113 provided on the side wall of the filling cavity 11 can be made of a transparent wear-resistant material, such as tempered glass. Through the observation window 113, the operator can intuitively observe the material level of graphite powder in the filling cavity 11, the working condition of the bag breaking tool, and the feeding status of graphite powder. For example, when graphite powder is blocked or abnormal at the sieve plate, the problem point can be located in time through the observation window 113, which greatly shortens the time for troubleshooting when feeding graphite powder. In addition, the observation window 113 can be movably connected to the outer wall of the filling cavity 11 through hinges and buckles. If an abnormal fault is found in the filling cavity 11, the observation window 113 can be opened after stopping feeding to deal with the abnormal situation in the filling cavity 11.

[0029] In one embodiment of this application, see reference Figure 2 As shown, the feed pipe 12 provided at the lower part of the first screen 111 is made of flexible canvas.

[0030] In the above embodiment, the feed pipe 12 is made of flexible canvas. On the one hand, the flexibility of the flexible pipe allows for a certain installation error and facilitates the adjustment of the docking position, making the connection between the feed pipe 13 and the feed pipe 12 more convenient and reducing the precision requirements for manufacturing and assembly. In addition, the flexible connection can effectively isolate the vibration transmitted from the vibration platform 23 to the upper packing structure, preventing strong vibration from affecting the screening efficiency of the upper screen and the stability of the structure, avoiding fatigue fracture of component connections due to long-term vibration, and helping to improve the stability of the device during operation.

[0031] In one embodiment of this application, see reference Figure 2As shown, a dust suction hood 121 is provided between the feed pipe 12 and the feed pipe 13. The dust suction hood 121 is connected to the first suction pipe through the second suction pipe. The first suction pipe is connected to the bag filter dust collector, which is located inside the packing section 1.

[0032] In the above embodiment, graphite powder is prone to overflow at the interface where the feed pipe 12 and the feed pipe 13 meet. The dust collection hood 121 is connected to the first suction pipe through the second suction pipe. The air drawn into the dust collection hood 121 through the first suction pipe creates a negative pressure inside the dust collection hood 121, which absorbs the graphite powder overflowing from the interface where the feed pipe 12 and the feed pipe 13 meet. The absorbed graphite powder is then passed into a bag filter for filtration and collection. On the one hand, this reduces the diffusion of graphite dust in the production workshop, lowers the dust concentration in the workshop air, protects the health of the staff, and meets the requirements of environmental protection and safe production. On the other hand, collecting graphite powder through the bag filter prevents graphite powder waste and helps improve the utilization efficiency of graphite powder.

[0033] In one embodiment of this application, see reference Figure 2 As shown, a first dust suction pipe is provided on one side of the packing chamber 11, and the first dust suction pipe is connected to the bag filter through a first air suction pipe.

[0034] In the above embodiment, the air inlet of the first dust suction pipe is located at the upper part of the packing cavity 11 to absorb the dust flying when the material is added into the packing cavity 11, and to prevent graphite dust from overflowing from the upper end of the packing cavity 11 into the production workshop, so as to reduce the diffusion of graphite dust in the production workshop.

[0035] In one embodiment of this application, see reference Figure 3 As shown, a second suction pipe is provided inside the vibrating section 2, and the air inlet of the second suction pipe faces the opening of the crucible 4.

[0036] In the above embodiment, during the process of graphite powder being injected into crucible 4 through the distribution pipe 22, and during the process of crucible 4 vibrating on the vibration platform 23, graphite dust is easily stirred up. The stirred-up dust can be absorbed by the second dust suction pipe, which can reduce the settling of graphite dust in areas such as the vibration platform 23 and the outer wall of crucible 4, and reduce the frequency of equipment cleaning and maintenance.

[0037] In one embodiment of this application, see reference Figure 3 As shown, the material distribution bin 21, crucible 4, and vibration platform 23 are arranged in the dust collection compartment 24, and a roller shutter door 241 is provided on one side of the dust collection compartment 24.

[0038] In the above embodiment, the dust collection compartment 24 is used to separate the material distribution bin 21, the crucible 4, and the vibration platform 23, blocking the graphite dust source and the vibration noise source to prevent dust and noise from spreading in the production workshop. A roller shutter door 241 is provided on one side of the dust collection compartment 24, which can be quickly opened when the crucible 4 needs to be replaced or maintained, providing ample operating space; it is closed during normal operation to provide sound and dust insulation, that is, to physically isolate the vibration and dust sources from the external production environment, which is beneficial to improving the cleanliness and comfort of the workshop.

[0039] In one embodiment of this application, see reference Figure 3 As shown, a vibrating screen 311 is provided between the first hopper 31 and the second hopper 32.

[0040] In the above embodiment, the vibrating screen 311 is disposed between the first hopper 31 and the second hopper 32 to screen the spilled and recovered powder, so as to separate the particle agglomerates or other particulate impurities that may be mixed in the recovered graphite powder, which facilitates the subsequent recovery of the collected graphite powder. In addition, pre-screening to remove impurities can prevent the recovery pipe and hopper from becoming blocked.

[0041] In one embodiment of this application, see reference Figure 3 As shown, a mixing and crushing assembly 211 is provided at the bottom of the material distribution bin 21.

[0042] In the above embodiment, the stirring and crushing component 211 at the bottom of the distribution bin 21 is used to continuously agitate and mix the graphite powder in the distribution bin 21, preventing the graphite powder from statically accumulating and agglomerating, keeping the graphite powder in a loose and uniform flow state, and preventing local accumulation and compaction of graphite powder. The blades or toothed structure are driven by a motor, which can directly cut and crush the agglomerates formed in the graphite powder. On the one hand, it can improve the uniformity of graphite powder when it is added to the crucible 4, and on the other hand, it can prevent the graphite powder from getting blocked during the conveying process of the device, avoiding production interruption, cleaning and maintenance time loss caused by blockage of the conveying pipeline, which is beneficial to improving the production efficiency and operational reliability of the device.

[0043] In actual use, the filling section 1, the compaction section 2, and the recovery section 3 are arranged vertically using a metal mounting frame. The filling section 1 is positioned above the compaction section 2, and the recovery section 3 is positioned below the compaction section 2. The filling section 1 contains a filling cavity 11 for pouring or adding graphite powder. For example, a movable lifting device is installed above the filling cavity 11 to lift a ton bag containing graphite powder into the filling cavity 11. The graphite powder packaging is then broken to allow the powder to fall into the filling cavity 11. A packaging-breaking cutter 112 is installed at the upper end of the first screen 111 to cut open the ton bag (i.e., the outer packaging of the graphite powder) lifted into the filling cavity 11, allowing the graphite powder to flow out. Furthermore, the bag-breaking cutter 112 consists of multiple blades arranged in a conical shape. When the ton bag comes into contact with the bag-breaking cutter 112, the conical blades collide and tear open the outer packaging. The edges of the cone can break open the outer packaging from multiple angles and directions. An observation window 113 is provided on the side wall of the filling chamber 11. Through the observation window 113, the operator can directly observe the material level of graphite powder in the filling chamber 11, the working condition of the bag-breaking tool, and the feeding status of graphite powder. A first screen 111 is provided at the bottom of the filling chamber 11 for preliminary screening and filtering of graphite powder. A feeding pipe 12 is provided below the first screen 111, and the feeding pipe 12 is connected to the conveying pipe 13. The feeding pipe 12 is made of flexible canvas. On the one hand, the flexibility of the flexible pipe allows for a certain installation error and facilitates the adjustment of the docking position, making the connection between the conveying pipe 13 and the feeding pipe 12 more convenient and reducing the precision requirements for manufacturing and assembly. In addition, the flexible connection can effectively isolate the vibration transmitted from the vibration platform 23 to the upper packing structure, preventing strong vibration from affecting the screening efficiency of the upper screen and the stability of the structure. Graphite powder enters the feed pipe 13 through the feed pipe 12. A dust suction hood 121 is provided between the feed pipe 12 and the feed pipe 13. The dust suction hood 121 is connected to the first suction pipe through the second suction pipe. The first suction pipe is connected to the bag filter dust collector. The bag filter dust collector is set in the packing part 1. Air is drawn into the dust suction hood 121 through the first suction pipe, which creates a negative pressure in the dust suction hood 121 to absorb the graphite powder overflowing from the interface between the feed pipe 12 and the feed pipe 13. The absorbed graphite powder is then passed into the bag filter dust collector for filtration and collection. The bottom end of the feed pipe 13 is connected to the distribution bin 21 in the compaction section 2, that is, graphite powder enters the distribution bin 21 in the compaction section 2 through the feed pipe 13. The bottom of the distribution bin 21 is connected to multiple distribution pipes 22. A crucible 4 is placed below the distribution pipes 22. The distribution pipes 22 are used to add graphite powder into the crucible 4.Optionally, each distribution pipe 22 is equipped with a pneumatic butterfly valve to control the opening and closing of the distribution pipe 22. The outlet of the distribution pipe 22 extends towards the opening of the crucible 4, and the air inlet of the second dust suction pipe faces the opening of the crucible 4. The second dust suction pipe absorbs the dust that is raised, which can reduce the settling of graphite dust in areas such as the vibrating platform 23 and the outer wall of the crucible 4. The crucible 4 is placed on the vibrating platform 23, and a vibration motor 231 is installed inside the vibrating platform 23. That is, the vibration motor 231 drives the vibrating platform 23, which in turn drives the crucible 4 to vibrate. The vibration causes the graphite particles to shift and rearrange in the crucible 4, making the graphite particles more compact. A first funnel is provided below the partition. When graphite powder is added to the crucible 4, the scattered graphite powder enters the discharge hopper in the recovery section 3 through the holes in the partition for recovery. A vibrating screen 311 is provided between the first hopper 31 and the second hopper 32. The vibrating screen 311 is located between the first hopper 31 and the second hopper 32 and is used to screen the spilled and recovered powder to separate the particle agglomerates or other particle impurities that may be mixed in the recovered graphite powder, so as to facilitate the later recovery of the collected graphite powder.

[0044] In addition, a stirring and crushing component 211 is provided at the bottom of the distribution bin 21 to continuously turn over and mix the graphite powder in the distribution bin 21, prevent the graphite powder from statically accumulating and agglomerating, keep the graphite powder in a loose and uniform flow state, and prevent local accumulation and compaction of graphite powder. The blades or toothed structure are driven by a motor and can directly cut and crush the agglomerates formed in the graphite powder.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
