Description

Technical Field

[0001] This utility model belongs to the field of crucible loading technology, specifically relating to an automatic filling device for graphitized crucibles. Background Technology

[0002] Currently, graphite-based materials still dominate the anode materials for commercial lithium-ion batteries. In the preparation process of graphite-based anode materials, it is necessary to first crush the blocky or large-particle natural graphite or artificial graphite precursor into powder particles of appropriate particle size, and then carry out carbonization and graphitization treatment to improve its capacity and cycle performance, so as to prepare qualified graphite-based anode materials.

[0003] In existing related technologies, graphite powder or natural graphite powder is directly loaded into the crucible. During the graphite compaction process, the powder is prone to leakage, causing pollution. Therefore, there is an urgent need to design an automatic filling device for graphitized crucibles to deal with these problems. Utility Model Content

[0007] The filling mechanism includes a gantry frame that is longitudinally and parallelly fixed on one side of the mixing and feeding mechanism. A lead screw is vertically and rotatably mounted on the gantry frame. A power motor is installed at one end of the lead screw. A lifting platform is installed on the outer surface of the lead screw. A movable limiting platform is fixedly mounted on the lifting platform. A lifting corrugated pipe is fixedly mounted on the middle of the upper part of the movable limiting platform.

[0013] The beneficial effects are:

[0014] This utility model discloses an automatic filling device for graphitization crucibles. Through a filling mechanism, a power motor drives a lead screw to rotate, which in turn drives a lifting platform and a moving limit platform mounted on the outer surface of the lead screw to rise and fall. This also drives a lifting bellows and a dustproof limit cover to rise and fall. After the dustproof limit cover is moved to the outer surface of the crucible body and compacted, graphite falls into the crucible body through the lifting bellows and the dustproof limit cover. An electric telescopic rod is then activated to push a compaction plate to fill and flatten the graphite inside the crucible body. When filling and flattening, graphite dust is generated. A dust removal component is activated to suck up and clean the dust through a suction pipe. After filling and flattening are completed, continuous filling is performed through the rotation of an intermittent component, ensuring the graphite compaction effect and removing dust, thus improving filling and compaction efficiency and demonstrating strong practicality.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Reference Figure 1-5One embodiment of this utility model is an automatic filling device for graphitization crucibles, including a base 1, a stirring and feeding mechanism 2 above the base 1, and a filling mechanism 3 on one side of the stirring and feeding mechanism 2.

[0025] In this embodiment: the mixing and feeding mechanism 2 includes a frame 201 fixedly mounted on one side above the base 1. A discharge bin 202 is fixedly installed on the frame 201. A discharge pipe 203 is fixedly installed above the discharge bin 202. A drive motor 204 is installed above the discharge bin 202. A mixing component is fixedly installed on the power end of the drive motor 204. A material quantity monitor 206 is fixedly installed on the discharge bin 202. A suction box 207 is fixedly installed at the lower end of the discharge bin 202. A suction pump 208 is fixedly installed on the suction box 207. A feed pipe 209 is fixedly installed on the suction pump 208. The mixing component includes a rotating rod 2041 located at the power end of the drive motor 204. An agitator blade 205 is fixedly installed on the outer surface of the rotating rod 2041. A mixing rod 2051 is fixedly installed at the lower end of the rotating rod 2041. An observation hole 210 is fixedly installed vertically on the front side of the discharge bin 202. A material quantity probe is movably mounted on the material quantity monitor 206 and is horizontally installed inside the discharge hopper 202, making contact with the graphite. A cap is movably mounted above the discharge pipe 203 to isolate the graphite in the discharge hopper 202 from the outside environment. One end of the feed pipe 209 is provided with a receiving metering chamber that is connected through it and is interconnected with the lifting corrugated pipe 305. The discharge hopper 202 is under positive pressure. An air pump (not shown in the diagram) on the receiving metering hopper draws air into the receiving metering hopper, creating a negative pressure. This pressure difference causes material to be blown from the discharge hopper 202 into the receiving metering hopper through the feed pipe 209. The pressure difference between the discharge hopper 202 and the receiving metering hopper is used to transport the material into the receiving metering hopper. The receiving metering hopper is connected to the feed inlet of the lifting corrugated pipe 305, completing the graphite filling of the crucible body 315. When the crucible body 315 is fully filled, the air pump stops pumping air, and the air pressure in the discharge hopper 202 and the receiving metering hopper becomes the same, stopping the material transport in the discharge hopper 202. A transparent material is installed on the observation hole 210 for easy observation of the interior of the discharge hopper 202.

[0026] In this embodiment: the filling mechanism 3 includes a portal frame 301 that is longitudinally and parallelly fixed on one side of the mixing and feeding mechanism 2. A lead screw 302 is vertically and rotatably mounted on the portal frame 301. A power motor 303 is provided at one end of the lead screw 302. A lifting platform 304 is provided on the outer surface of the lead screw 302. A movable limiting platform 3041 is fixedly mounted on the lifting platform 304. A lifting corrugated pipe 305 is fixedly mounted at the middle of the upper part of the movable limiting platform 3041. A dustproof limiting cover 306 is fixedly provided at the lower end of the movable limiting platform 3041. A compacted base plate 308 is movably installed inside the cover 306. A compacted plate 309 is located below the compacted base plate 308. An electric telescopic rod 307 is installed above the compacted base plate 308. A dust suction pipe 310 is fixedly installed on the dustproof limit cover 306. A dust removal component is fixedly installed at one end of the dust suction pipe 310. A rotating shaft 312 is rotatably installed above the base 1. A support platform 314 is fixedly installed at one end of the rotating shaft 312. A crucible body 315 is movably arranged above the support platform 314. An intermittent component is fixedly installed at the other end of the rotating shaft 312. The dust removal component includes a dust collection box 3101 fixedly installed at one end of the dust suction pipe 310, and a dust collector 311 fixedly installed on the dust collection box 3101. The intermittent component includes a grooved wheel 313 located at the other end of the rotating shaft 312. A grooved rod 3131 is provided on one side of the grooved wheel 313, and a first motor 3132 is provided at one end of the grooved rod 3131. The lifting bellows 305 and the dustproof limiting cover 306 are connected via a connecting inclined tube. A damping spring is installed between the compaction plate 309 and the compaction base plate 308. Limiting plates are installed at the upper and lower ends of the outer surface of the lead screw 302. The outer diameters of the compaction plate 309 and the compaction base plate 308 are smaller than the inner diameter of the dustproof limiting cover 306, allowing the compaction plate 309 and the compaction base plate 308 to move up and down easily within the dustproof limiting cover 306. The crucible body 315 is movably placed within the limiting platform. The outer diameter of the limiting platform is the same as the outer diameter of the dustproof limiting cover 306. The outer diameter of the crucible body 315 is the same as the inner diameter of the dustproof limiting cover 306.

[0027] Working Principle: In operation, the drive motor 204 is first started to rotate the rotating rod 2041, stirring blade 205, and agitator 2051. Graphite material is fed into the discharge hopper 202 through the feed pipe 203. The rotating rod 2041, stirring blade 205, and agitator 2051 stir the graphite material, while the material quantity monitor 206 monitors the amount of graphite material. After stirring for a certain period, the suction pump 208 is started, drawing the graphite material into the receiving metering hopper and lifting bellows 305 through the suction box 207 and feed pipe 209. The power motor 303 is then started to rotate the lead screw 302 clockwise, driving the lifting platform 304, moving limit platform 3041, and lifting bellows 305 to descend. The inner surface of the dustproof limit cover 306 contacts the outer surface of the crucible body 315, and the lowering continues until a certain position is reached, at which point the movement stops. The graphite material in the receiving metering bin and the lifting corrugated pipe 305 is fed into the crucible body 315 through the connecting inclined pipe. The electric telescopic rod 307 is activated to push the compaction plate 309 and the compaction base plate 308 downward, compressing the graphite material in the crucible body 315. During the compression, dust is generated. The dust collector 311 is activated to extract and collect the dust through the dust suction pipe 310 and the dust collection box 3101. After the graphite material in the crucible body 315 is filled, the power motor 303 is activated to drive the lead screw 302 to rotate counterclockwise, driving the lifting platform 304, the moving limit platform 3041, and the lifting corrugated pipe 305 to rise. The first motor 3132 is activated to drive the grooved rod 3131 to rotate, and engages with the grooved wheel 313 on one side to rotate, driving the support platform 314 and the crucible body 315 to rotate intermittently, repeating the graphite material filling process to complete the continuous filling.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
