Description

Technical Field

[0001] The invention relates to the technical field of lithium battery production equipment, in particular to a graphite coating carbonization equipment for producing lithium battery electrodes. Background Art

[0002] Graphite materials such as graphite powder and graphite film are increasingly being used due to their unique electrical and thermal properties. Graphite used in lithium-ion batteries has the advantages of high operating voltage, high specific energy, light weight, small size, long cycle life, fast charging and discharging, and no environmental pollution. However, the compatibility of graphite with electrolyte is poor, which limits the application of pure graphite in lithium-ion batteries. Therefore, the graphite material must be modified, and a layer of amorphous carbon material must be coated on the graphite surface to increase the tap density and increase the battery charge and discharge capacity. The reaction process of coated graphite is generally to first disperse the graphite in a liquid coating material or a molten coating material, then evaporate the solvent or the coating material to coat the amorphous carbon precursor on the surface of the graphite material, and then carbonize it. At present, most of the graphite coating carbonization equipment is a carbonization furnace, which is used to dry the graphite coating material to carbonize it. However, the existing carbonization furnace is large in size and takes up more space. In addition, before carbonization, the graphite needs to be wrapped with carbon material and then transported to the carbonization furnace, which is time-consuming and labor-intensive.

[0003] For example, patent application number CN201820811492.6 specifically relates to a graphite coated carbonization furnace, the structure of which can rapidly cool down the interior of the furnace through condensed water, and use a fan to pass argon into the furnace to protect the graphite material. The fan can also fully circulate the gas in the furnace so that the hot air can fully contact with the condensed water, thereby improving the overall cooling efficiency. At the same time, the temperature distribution of the carbonization furnace is uniform, which is conducive to the forming of the graphite material. However, the carbonization furnace itself is large in size and occupies more space. In addition, the graphite carbon material needs to be manually transported to the carbonization furnace before carbonization, which is time-consuming and labor-intensive. Summary of the invention

[0037] See also Figure 8-9 The surface of the rotating plate 421 is fixedly provided with a sliding groove 421-1, the inner cavity of the sliding groove 421-1 is fixedly connected with a sliding rod 421-2, the surface of the sliding rod 421-2 is slidably sleeved with a telescopic plate 421-3, the surface of the telescopic plate 421-3 and the inner cavity of the sliding groove 421-1 are mutually matched, and the surface is flush, the surface of the telescopic plate 421-3 is provided with a handle 421-5, the telescopic plate 421-3 and the side interlayer of the workbench 1 are both provided with a magnetic strip 421-4, the corner of the surface of the rotating plate 421 is provided with a groove 421-6, the groove 421-6 The inner wall is fixedly connected to a metal spring 421-8, and the inner cavity of the groove 421-6 is rotatably connected to a supporting foot 421-7, which is movably engaged in the inner cavity of the metal spring 421-8.

At the same time, the frame plate 422 and the rotating plate 421 can also be folded up to achieve a storage effect.

[0038] See also Fig.10 The molding die 4210 includes a hollow plate 2101 fixedly connected to the surface of the conveyor belt 428, a spring 2105 is symmetrically fixedly connected to the inner wall of the hollow plate 2101, one end of the spring 2105 is fixedly connected to a clamping block 2104, a molding cavity plate 2102 is slidably sleeved on the surface of the hollow plate 2101, and a screw 2103 is threadedly sleeved on the surface of the molding cavity plate 2102. By replacing the molding cavity plate 2102, the coating material liquid graphite can be carbonized into carbonized coated graphite of different sizes in the corresponding molding cavity plate 2102.

[0039] During the stirring operation, the servo motor 417 is first started through the control panel 2, and the meshing connection of the chain 418 and the sprocket wheel 419 drives the screw rod 415 to rotate, and as the screw rod 415 rotates, the top cover 413 on the surface moves upward on the surface of the screw rod 415. The top cover 413 is removed from the port of the mixing drum 412, and then the graphite and the coating material are simultaneously placed in the inner cavity of the mixing drum 412, and then the servo motor 417 is reversed to cover the top cover 413 on the port of the mixing drum 412, and then the driving motor 414 is started, and the output end of the driving motor 414 drives the stirring blade 4112 to rotate, so that the graphite and the coating material are stirred and mixed to form the coating material liquid graphite, and then the solenoid valve 4111 is opened to transport the coating material liquid graphite along the discharge pipe 4110 to the connecting pipe 424.

[0040] During the carbonization operation, the coating material liquid will flow into the forming mold 4210 through the connecting pipe 424, and then the motor 429 will be started through the supporting leg 3, so that the output end of the heating tube 426 drives the roller 427 to rotate, thereby driving the conveyor belt 428 to rotate, and also driving the forming mold 4210 on the surface to move. When the forming mold 4210 moves to the bottom of the infrared actuator 4212 and is sensed by the infrared actuator 4212, the rotation of the motor 429 will be automatically stopped, so that the forming mold 4210 is located below the extrusion plate 4214, and then the electric push rod 4213 will be started, so that the telescopic end of the electric push rod 4213 drives the extrusion plate 4214 to move downward. The coating material liquid in the molding die 4210 is flattened and reset, and then the heating tube 426 and the motor 429 are started. The heating of the heating tube 426 will dry the coating material liquid in the molding die 4210, so that it is dried and carbonized. At the same time, the motor 429 continues to drive the molding die 4210 to continue to move. As the molding die 4210 moves, the carbonized coated graphite in the molding die 4210 will fall from the molding die 4210 into the collection box prevented by the conveyor belt 428, and the carbonized graphite is automatically transported by the stirring mechanism 41 and the carbonization mechanism 42, so as to solve the problem that the graphite needs to be wrapped with carbon material before carbonization and then transported to the carbonization furnace, which is time-consuming and labor-intensive.

[0041] Since there are multiple molding molds 4210 and the distance between them is the same, when the first molding mold 4210 with coating liquid is flattened, the subsequent molding mold 4210 will be located below the connecting tube 424, so that the connecting tube 424 will continue to flow the coating material liquid into the molding mold 4210 in sequence, so as to achieve cyclic carbonization.

[0042] The molding die 4210 is installed by first sliding the molding cavity plate 2102 onto the surface of the hollow plate 2101, and at the same time, the elastic force of the spring 2105 drives the clamping block 2104 to extrude the molding cavity plate 2102, so that the molding cavity plate 2102 can always be kept in the center position under the elastic force of the spring 2105, and then the screw 2103 is turned to fasten the molding cavity plate 2102 to the hollow plate 2101, and the coating material liquid will flow into the molding cavity on the top of the molding cavity plate 2102. In addition, the corresponding molding cavity plate 2102 can be replaced according to the size of the carbonized coated graphite required, so that the molding of carbonized coated graphite of different sizes can be completed.

[0043] During the storage work, when the work is completed, one end of the discharge pipe 4110 can be removed from the port of the connecting pipe 424, and then the rotating plate 421 is pulled up and flush with the side of the workbench 1, so that the frame plate 422 enters the inner cavity of the workbench 1, and then the telescopic plate 421-3 is pulled out from the sliding rod 421-2 in the sliding groove 421-1 through the handle 421-5, so that the telescopic plate 421-3 is against the inner wall of the side interlayer of the workbench 1, and is attracted to each other through the magnetic strip 421-4 (wherein the top of the telescopic plate 421-3 and the inner wall of the side interlayer of the workbench 1 are correspondingly provided with mutually attracting magnetic strips 421-4, so that the rotating plate 421 and the telescopic plate 421-3 can be closed on the side of the workbench 1), and finally the supporting foot 421-7 is rotated to enter the groove 421-6, and clamped in the inner cavity of the metal spring sheet 421-8 to prevent it from leaking out. By storing the carbonization mechanism 42, the volume of the carbonization equipment can be reduced, thereby reducing the occupied area.
