Description

TECHNICAL FIELD

[0001] The utility model relates to the field of graphene preparation technology, concretely to a graphene heat-conducting paste preparation device convenient for feeding. BACKGROUND

[0002] Graphene heat-conducting paste is a high-thermal-conductivity mixture with graphene as the main component, usually composed of graphene, solvent or carrier material (such as polymer) and other additives. When preparing graphene heat-conducting paste, it is usually mixed by a preparation device. The paste with excellent thermal conductivity is prepared mainly by uniformly mixing graphene powder and liquid base (such as solvent or polymer).

[0003] The patent with the publication number CN221693378U discloses a graphene carbon nanotube heat-conducting paste preparation device, which includes a shell. The upper surface of the shell is movably connected with a top cover through a first bolt. The middle part of the upper surface of the top cover is fixedly connected with a motor. The output end of the motor is fixedly connected with a rotating rod. The middle part of the outer surface of the rotating rod is fixedly connected with a spiral stirring blade. One side of the upper surface of the top cover is fixedly connected with a compressed air pump. The graphene carbon nanotube heat-conducting paste preparation device is driven by the motor to rotate the rotating rod, so that the spiral stirring blade stirs and mixes the paste, increases the movement between the pastes, and the compressed air pump flows gas into the inside of the fixed pipe along the conveying pipe through multiple nozzles. The gas flow stirs the paste, promotes the mixing and stirring of the paste, improves the stirring efficiency of the paste, and makes the stirring more uniform and thorough, thereby enhancing the mixing efficiency.

At the same time, the flowability during the feeding process may make the feeding process less convenient and accurate, which may cause waste of raw materials. In addition, the paste may be left in the inner wall of the equipment during the preparation process, which makes the subsequent cleaning process difficult and thus affects the subsequent processing.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the scope of the utility model protection.

[0029] Please refer to Figures 1-7 The utility model provides a kind of technical scheme: a kind of graphite alkene heat-conducting paste preparation device of convenient feeding, it includes: preparation cauldron 1, cover plate 2, rotating shaft 3, threaded rod 4, rubber scraper 5, synchronous pulley 6, first motor 7, belt 8, shunt bin 9, blanking tube 10, transmission groove 11, spiral rod 12, first bevel gear 13, second motor 14, second bevel gear 15, stock bin 16, rotating rod 17, separating plate 18, gear 19, rack 20, electric push rod 21.

[0030] Firstly, as shown in the drawings Figure 1 , as shown in the drawings Figure 2 , as shown in the drawings Figure 3 , as shown in the drawings Figure 4As shown in the middle, when the graphene heat-conducting paste is prepared by the preparation device, the hopper 16 is fixedly installed on the top of the cover plate 2, and the shunt bin 9 is also fixedly installed on the top of the cover plate 2. Then the raw materials are poured into the hopper 16 through the feeding port on the hopper 16. Since the hopper 16 is arranged in a “W” shape, and the left and right ends of the bottom of the hopper 16 are arranged in a communication state with the shunt bin 9, the raw materials poured into the hopper 16 enter the inside of the shunt bin 9. Since the transmission groove 11 is fixedly installed at the middle position of the inside of the shunt bin 9, the left and right ends of the inside of the shunt bin 9 are also rotatably connected with the screw rod 12, and the screw rod 12 extends through the inside of the transmission groove 11. The first bevel gear 13 is fixedly installed at one end of the screw rod 12 in the inside of the transmission groove 11. The second motor 14 is fixedly installed at the rear end of the shunt bin 9, and the second motor 14 is fixedly installed with the second bevel gear 15 at one end in the inside of the transmission groove 11. The second bevel gear 15 is meshed with the first bevel gear 13. The second motor 14 is started to drive the screw rod 12 to rotate through the meshing between the second bevel gear 15 and the first bevel gear 13, and the screw rods 12 at the left and right ends in the inside of the shunt bin 9 rotate in opposite directions, so that the raw materials in the shunt bin 9 are moved by the screw rod 12. The left and right ends of the bottom of the shunt bin 9 are fixedly installed with the discharge pipe 10, and the pipe body of the discharge pipe 10 is arranged in a communication state with the cover plate 2. The raw materials in the shunt bin 9 are conveyed into the inside of the preparation kettle 1 through the discharge pipe 10 by the rotation of the screw rod 12. The raw materials in the preparation kettle 1 are prepared by the preparation kettle 1. The raw materials are shunted by the cooperation between the shunt bin 9, the discharge pipe 10 and the screw rod 12, and the feeding process is more convenient. The flowability of the raw materials is improved by the rotation of the screw rod 12, and the time required for feeding is reduced.

[0031] As shown in the middle, when the graphene heat-conducting paste is prepared by the preparation device, the hopper 16 is fixedly installed on the top of the cover plate 2, and the shunt bin 9 is also fixedly installed on the top of the cover plate 2. Then the raw materials are poured into the hopper 16 through the feeding port on the hopper 16. Since the hopper 16 is arranged in a “W” shape, and the left and right ends of the bottom of the hopper 16 are arranged in a communication state with the shunt bin 9, the raw materials poured into the hopper 16 enter the inside of the shunt bin 9. Since the transmission groove 11 is fixedly installed at the middle position of the inside of the shunt bin 9, the left and right ends of the inside of the shunt bin 9 are also rotatably connected with the screw rod 12, and the screw rod 12 extends through the inside of the transmission groove 11. The first bevel gear 13 is fixedly installed at one end of the screw rod 12 in the inside of the transmission groove 11. The second motor 14 is fixedly installed at the rear end of the shunt bin 9, and the second motor 14 is fixedly installed with the second bevel gear 15 at one end in the inside of the transmission groove 11. The second bevel gear 15 is meshed with the first bevel gear 13. The second motor 14 is started to drive the screw rod 12 to rotate through the meshing between the second bevel gear 15 and the first bevel gear 13, and the screw rods 12 at the left and right ends in the inside of the shunt bin 9 rotate in opposite directions, so that the raw materials in the shunt bin 9 are moved by the screw rod 12. The left and right ends of the bottom of the shunt bin 9 are fixedly installed with the discharge pipe 10, and the pipe body of the discharge pipe 10 is arranged in a communication state with the cover plate 2. The raw materials in the shunt bin 9 are conveyed into the inside of the preparation kettle 1 through the discharge pipe 10 by the rotation of the screw rod 12. The raw materials in the preparation kettle 1 are prepared by the preparation kettle 1. The raw materials are shunted by the cooperation between the shunt bin 9, the discharge pipe 10 and the screw rod 12, and the feeding process is more convenient. The flowability of the raw materials is improved by the rotation of the screw rod 12, and the time required for feeding is reduced. Figure 1 , attached Figure 2 , attached Figure 3 , attached Figure 6As shown, when raw materials are poured into the hopper 16, and simultaneously fed into the preparation vessel 1 via the connection between the hopper 16 and the diversion chamber 9, two sets of electric push rods 21 are installed at the rear end of the top of the hopper 16, and racks 20 are slidably connected to both ends of the top of the hopper 16. The output ends of the electric push rods 21 are connected to the rear ends of the racks 20. Rotating rods 17 are rotatably connected to both ends inside the hopper 16, and gears 19 are fixedly installed on the upper end of the rotating rods 17. The racks 20 and gears 19 mesh with each other, thereby controlling the operation of the two sets of electric push rods 21 simultaneously or separately. The electric push rod 21 drives the rack 20 to slide on the top of the hopper 16, and the rack 20 and the gear 19 mesh with each other, which can synchronously drive the rotating rod 17 to rotate inside the hopper 16. Since the separating plate 18 is fixedly installed on the rod body of the rotating rod 17 and the separating plate 18 is set in a mesh state, when the rotating rod 17 rotates, it can synchronously drive the separating plate 18 to rotate. Thus, the reciprocating extension and retraction of the electric push rod 21 can drive the separating plate 18 to rotate in both directions. The mesh state and the forward and reverse rotation of the separating plate 18 can stir the raw materials inside the hopper 16, thereby effectively preventing the accumulation or agglomeration of raw materials and maintaining the fluidity of raw materials during the feeding process.

[0032] As attached Figure 1 Appendix Figure 5 and attached Figure 7 As shown, after the graphene thermal conductive slurry is prepared in the preparation vessel 1, the first motor 7 can be started. Then, a threaded rod 4 is rotatably connected to the inner top of the cover plate 2, and a rotating shaft 3 is rotatably connected to the lower end inside the preparation vessel 1. The lower end of the threaded rod 4 is oriented in a directional state, and the lower end of the threaded rod 4 is inserted and connected to the rotating shaft 3. Since the synchronous pulley 6 on the upper end of the threaded rod 4 is connected to the synchronous pulley 6 on the output end of the first motor 7 through a belt 8, the operation of the first motor 7 can drive the threaded rod 4 to rotate inside the preparation vessel 1. Then, the rod of the threaded rod 4 is connected to the rubber scraper 5 through threads, and the diameter of the rubber scraper 5 is the same as the diameter of the inner wall of the preparation vessel 1. The rotation of the threaded rod 4 can drive the rubber scraper 5 to form a lifting structure, so that the rubber scraper 5 can scrape the inner wall of the preparation vessel 1, which simplifies the cleaning process of the inner wall of the preparation vessel 1 and reduces the residue of raw materials on the inner wall of the preparation vessel 1.
