Description

Technical Field

[0001] This invention relates to the field of graphene raw material preparation technology, and in particular to a high-efficiency, low-consumption continuous preparation device for graphene raw materials. Background Technology

[0002] Graphene is the thinnest and hardest known two-dimensional nanomaterial, with a single thin layer composed only of regularly arranged carbon atoms, possessing outstanding mechanical and electrical properties. Its strength far exceeds that of conventional metals, it exhibits excellent electrical and thermal conductivity, is not easily deformed or damaged, and is suitable for various composite modification processes. It is often fused with various metals to prepare graphene-metal composites, which can significantly optimize matrix strength, conductivity, and corrosion resistance. With its comprehensive and outstanding physicochemical properties, graphene has a wide range of applications, covering electronic devices, energy storage batteries, precision machinery, anti-corrosion coatings, and many other fields, making it a novel functional material with great development potential.

[0003] Patent CN216512878U discloses a graphene production and preparation device, including a support mechanism, a fixing mechanism, a preparation mechanism, and a stirring mechanism. The fixing mechanism is located at the upper end of the support mechanism, the preparation mechanism is located at the inner end of the fixing mechanism, and the stirring mechanism is located at the upper end of the preparation mechanism. The support mechanism includes a worktable, a fixed support frame, connecting feet, movable rollers, a push-pull drawer, and a handle. The fixed support frame is fixedly installed at the lower end of the worktable. In this graphene production and preparation device, the fixing plate can fix and limit the preparation cylinder to prevent it from falling during operation, and the shock-absorbing spring can dampen vibrations at the outer end of the preparation cylinder, effectively reducing the vibration generated during operation and improving the stability of the device. The heater and heating tube can continuously heat the inside of the preparation cylinder, allowing the graphene raw material inside the preparation cylinder to be effectively dispersed and recombined, thus improving the working efficiency of the device.

[0004] There are still some problems in the processing of graphene raw materials.

[0005] Graphene raw materials often contain coarse particles, which are prone to agglomeration. Direct stirring will result in uneven dispersion, affecting the performance of the composite material. Traditional processing equipment often uses separate and independent operations for conveying, grinding, and stirring. Material transfer is prone to dust and loss, the process is not connected, and the production efficiency is low. Existing mixing tanks lack built-in crushing structures, so coarse particles cannot be refined simultaneously in the tank. External mills are required for repeated cyclic grinding, which takes up a lot of space and is cumbersome to operate. Summary of the Invention

The bottom end of the drive rod 317 is fixedly connected to the output end of the second motor 318. The second motor 318 is fixedly installed on one side of the frame 104.

[0038] Specifically, when the material enters the conical groove 302, the main shaft 313 rotates, driving the second pulley 312 to rotate. The rotation of the second pulley 312 drives the first pulley 307 to rotate via the first transmission belt 308. The first pulley 307 is fixedly connected to the top of the driven shaft 305. The rotation of the first pulley 307 causes the driven shaft 305 to rotate. The bottom end of the driven shaft 305 is fixedly connected to an arm plate 304, and one end of the arm plate 304 is rotatably connected to a grinding roller 303. The grinding roller 303 is located inside the conical groove 302.

[0040] Specifically, when the material enters the material cylinder 1, the operation of the second motor 318 causes the fourth pulley 316 on the first pulley 307 to rotate. The rotation of the fourth pulley 316 drives the third pulley 314 to rotate through the second transmission belt 315. The third pulley 314 is fixedly connected to the top of the main shaft 313. The rotation of the third pulley 314 drives the main shaft 313 to rotate. The rotation of the main shaft 313 causes the docking plate 402 to rotate. A rod 403 is rotatably connected to the docking plate 402, and a gear 404 is fixedly connected to the top of the rod 403. The movement of the rod 403 causes the gear 404 to engage with the gear ring 405 and rotate, thereby facilitating the rotation of the rod 403 and causing the stirring rod 408 on the bottom plate 407 to stir the material.

[0041] The working principle of this invention is as follows: Material is added into the feed hopper 206 and then enters the interior of the conveying cylinder 201. Inside the conveying cylinder 201, a spiral conveying rod 203 is rotatably connected. The operation of the first motor 204 causes the spiral conveying rod 203 to rotate.

At the bottom position of the conveying cylinder 201, a discharge hopper 202 is fixedly connected. The material inside the conveying cylinder 201 enters the interior of the conical groove 302 through the discharge hopper 202.

[0042] When the material enters the conical groove 302, the main shaft 313 rotates, driving the second pulley 312 to rotate. The rotation of the second pulley 312 drives the first pulley 307 to rotate via the first transmission belt 308. The first pulley 307 is fixedly connected to the top of the driven shaft 305. The rotation of the first pulley 307 causes the driven shaft 305 to rotate. The bottom end of the driven shaft 305 is fixedly connected to an arm plate 304, and one end of the arm plate 304 is rotatably connected to a grinding roller 303. The grinding roller 303 is located inside the conical groove 302. The rotation of the driven shaft 305 causes the grinding roller 303 to crush the material inside the conical groove 302 via the arm plate 304.

[0043] When the material enters the material cylinder 1, the operation of the second motor 318 causes the fourth pulley 316 on the first pulley 307 to rotate. The rotation of the fourth pulley 316 drives the third pulley 314 to rotate through the second transmission belt 315. The third pulley 314 is fixedly connected to the top of the main shaft 313. The rotation of the third pulley 314 drives the main shaft 313 to rotate. The rotation of the main shaft 313 causes the docking plate 402 to rotate. A rod 403 is rotatably connected to the docking plate 402, and a gear 404 is fixedly connected to the top of the rod 403. The movement of the rod 403 causes the gear 404 to engage with the gear ring 405 and rotate, thereby facilitating the rotation of the rod 403 and causing the stirring rod 408 on the bottom plate 407 to stir the material.
