Description

Technical Field

[0001] This utility model relates to the field of graphene storage, specifically to a new energy graphene material storage device. Background Technology

[0002] Graphene is a material with many unique properties and enormous potential in the field of new energy. Graphene is composed of a single layer of carbon atoms arranged in a hexagonal structure, exhibiting extremely high electrical and thermal conductivity, strength, and flexibility. Graphene can be applied in new energy fields, such as in batteries. Graphene slurry (containing graphene powder, solvents, dispersants, binders, additives, etc.) can be coated onto electrode sheets to improve the electrical performance of batteries.

[0003] Currently, graphene slurry is stored in storage tanks. When needed, the graphene slurry is released from the storage tank for use. If the graphene slurry is stored for a long time, it needs to be stirred before release to ensure that the internal components of the graphene slurry are mixed evenly.

[0004] The flowability of graphene slurry is temperature-dependent. At low temperatures, the flowability of graphene slurry decreases, primarily due to: 1. Increased solvent viscosity: As temperature decreases, solvent viscosity typically increases, leading to reduced slurry flowability. 2. Enhanced interactions between graphene sheets: Low temperatures increase the attractive forces between graphene sheets, causing aggregation and sedimentation, further affecting slurry flowability. 3. Reduced dispersant effectiveness: Some dispersants lose some of their dispersing effect at low temperatures, reducing the dispersibility of graphene and also impacting slurry flowability.

[0005] Therefore, as the temperature increases, the fluidity of the graphene slurry improves, thereby reducing the resistance to stirring and enhancing the stirring effect. However, current storage tanks do not have a heating function, so the fluidity of the graphene slurry is poor at low temperatures, resulting in greater stirring resistance. Utility Model Content

[0006] The present invention aims to provide a new energy graphene material storage device to achieve heating of graphene slurry and solve the problem of poor fluidity of graphene slurry at low temperatures.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a new energy graphene material storage device, comprising a storage tank and a stirring mechanism, the stirring mechanism comprising a vertical stirring shaft and stirring blades, the stirring shaft extending into the storage tank, the stirring blades and the stirring shaft being fixedly connected, the stirring blades being vertically arranged; a motor for driving the stirring shaft to rotate is provided on the outside of the storage tank; the stirring shaft is provided with a discharge channel and a feed trough, the feed trough being located at the top of the stirring shaft, the discharge channel being arranged along the axial direction of the stirring shaft, the bottom of the discharge channel being sealed, and the top of the discharge channel being connected to the outside of the stirring shaft; The mixing blade has a horizontal discharge channel, a vertical intermediate channel, and a horizontal return channel inside. The intermediate channel connects the discharge channel and the return channel; the discharge channel is connected to the feed chute; and the return channel is connected to the bottom of the discharge channel.

[0008] The principle and advantages of this scheme are as follows: The storage tank is used to hold graphene slurry. A motor drives the stirring shaft to rotate, which in turn drives the stirring blades, thus achieving stirring of the graphene slurry within the storage tank. Before or during stirring, a heating medium is introduced into the feed trough of the stirring shaft. Since the discharge channel and the feed trough are connected, the heating medium enters the discharge channel from the feed trough. Because the intermediate channel connects the discharge channel and the return channel, the heating medium enters the intermediate channel from the discharge channel and then enters the return channel. The heating medium then enters the discharge channel along the return channel and moves upwards along the discharge channel, finally flowing out from the stirring shaft. After being heated, the heating medium re-enters the feed trough, thus creating a cyclical flow. In this way, heating medium continuously flows through the discharge channel, intermediate channel, and return channel on the stirring blade. The heating medium heats the stirring blade, and the stirring blade heats the graphene slurry. This solves the problem of poor fluidity of graphene slurry at low temperatures, improves the fluidity of graphene slurry, helps reduce stirring resistance, and improves the stirring effect.

[0009] In addition, the stirring blades in this design have a heating function. The stirring blades can stir and heat at the same time. Heating while the stirring blades are rotating is more conducive to the graphene slurry in different parts of the storage tank coming into full contact with the heat dissipation compared to heating while the stirring blades are stationary. This results in more uniform heating of the graphene slurry and a better heating effect.

[0010] In addition, the heating method of this solution allows the graphene slurry to be heated simply by the heating medium flowing through the stirring blades. There is no need to set up an additional heating structure inside the storage tank, so it will not occupy extra space inside the storage tank and will not affect the normal stirring of the graphene slurry.

[0011] Preferably, as an improvement, there are multiple stirring blades, which are distributed around the stirring shaft. This arrangement of multiple stirring blades increases the contact area between the blades and the graphene slurry, thereby improving the heating efficiency of the graphene slurry. When multiple stirring blades are used, the heating medium in the feed trough enters into multiple stirring blades, thus heating them. The heating medium from all the stirring blades simultaneously enters the discharge channel and flows upwards.

[0012] Preferably, as an improvement, there are multiple intermediate channels, which are arranged in parallel and are all connected between the discharge channel and the return channel.

[0013] Therefore, multiple intermediate channels are set on each stirring blade, thereby increasing the contact area between the stirring blade and the graphene slurry and improving the heating efficiency of the graphene slurry.

[0014] Preferably, as an improvement, the aperture of the multiple intermediate flow channels gradually increases from the end of the stirring blade near the stirring shaft to the end of the stirring blade away from the stirring shaft.

[0015] Therefore, the orifice diameter of the intermediate flow channel located at the end of the stirring blade furthest from the stirring shaft is the largest, while the orifice diameter of the intermediate flow channel closest to the stirring shaft is the smallest. The orifice diameter of the intermediate flow channels gradually increases from the smallest to the largest. This design is because the tank wall dissipates heat outwards. The slurry closer to the tank wall dissipates more heat, while the slurry farther from the tank wall dissipates less. If the orifice diameters of all intermediate flow channels were the same size, the heating effect of the slurry closer to the tank wall would be lower than that of the slurry farther from the tank wall. Therefore, to avoid this problem, the orifice diameters of the multiple intermediate flow channels are set to gradually increase from the stirring shaft towards the tank wall, thereby improving the heating effect of the slurry closer to the tank wall, compensating for the heat dissipated from the tank wall, and ensuring the uniformity of heating of the entire slurry within the tank.

[0016] Preferably, as an improvement, a driven gear is coaxially fixedly connected to the stirring shaft, and a driving gear is coaxially fixedly connected to the output shaft of the motor, with the driven gear and the driving gear meshing.

[0017] Thus, the motor drives the drive gear to rotate, the drive gear drives the driven gear to rotate, and the driven gear drives the stirring shaft to rotate, thereby achieving the drive to rotate the stirring blades.

[0018] Preferably, as an improvement, the top end of the stirring shaft is provided with a first rotating head, and a feed nozzle is connected to the first rotating head.

[0019] Therefore, the external heating medium, after being heated, enters the feed nozzle and then the first rotating head, which in turn enters the feed trough of the stirring shaft. Since the stirring shaft and the first rotating head are rotatably connected, the first rotating head remains stationary while the stirring shaft rotates. This ensures that the external heating medium is injected into the feed trough through the stationary first rotating head. The design of the first rotating head also allows the heating medium to be injected into the feed trough even when the stirring shaft is rotating.

[0020] Preferably, as an improvement, the discharge channel and the stirring shaft are coaxially arranged; the feed trough and the stirring shaft are coaxially arranged, and the discharge channel is located below the feed trough; a material cylinder is fixedly installed inside the feed trough, and the material cylinder and the discharge channel are coaxially arranged and connected; the top of the material cylinder is located above the stirring shaft.

[0021] Thus, the feed cylinder extends above the top of the stirring shaft. The heating medium flowing upward from the discharge channel enters the feed cylinder and flows out of the feed cylinder, thereby realizing the flow of the heating medium from the stirring shaft. The feed cylinder has the function of guiding the heating medium from inside the discharge channel of the stirring shaft to the outside of the stirring shaft. At the same time, the feed cylinder also has the function of isolating the heating medium entering the feed trough from the heating medium exiting from the discharge channel.

[0022] Preferably, as an improvement, a second rotating head is rotatably provided at the top of the barrel, and a discharge nozzle is connected to the second rotating head. Thus, the heating medium flowing from the barrel enters the second rotating head and flows out through the discharge nozzle. Because the second rotating head and the barrel are rotatable, while the stirring shaft drives the barrel to rotate, the second rotating head remains stationary, allowing the heating medium in the barrel to flow steadily out of the discharge nozzle through the stationary second rotating head. The arrangement of the second rotating head ensures that the heating medium can be discharged from the barrel even when the stirring shaft is rotating.

[0023] Preferably, as an improvement, the number of intermediate channels is three.

[0024] Preferably, as an improvement, there are four stirring blades.

[0025] Preferably, as an improvement, a blocking block is fixedly connected to the bottom of the stirring shaft to block the discharge channel. The blocking block achieves bottom blocking of the discharge channel. Attached Figure Description

[0031] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: tank body 1, support leg 2, discharge pipe 3, feed pipe 4, tank cover 5, motor 6, drive gear 7, stirring shaft 8, driven gear 9, first rotating head 10, feed nozzle 11, second rotating head 12, discharge nozzle 13, material cylinder 14, discharge channel 15, stirring blade 16, return channel 17, sealing block 18, feed trough 19, discharge channel 20, intermediate channel 21.

[0032] The basic implementation examples are as follows: Figures 1-5 The diagram shows a new energy graphene material storage device, comprising a storage tank and a stirring mechanism. In this embodiment, the storage tank is cylindrical, with support legs 2 welded to its bottom. The storage tank includes a tank body 1 and a lid 5 covering the top of the tank body 1. A feed pipe 4 is provided on the lid 5, and a discharge pipe 3 is provided at the bottom of the tank body 1. The feed pipe 4 allows graphene slurry to be added to the tank body 1, and the discharge pipe 3 allows the stirred graphene slurry to be discharged. Both the feed pipe 4 and the discharge pipe 3 are fixed with cover plates via flange structures, thus sealing the feed pipe 4 and discharge pipe 3 when not in use.

[0033] Combination Figure 3 and Figure 4 As shown, in this embodiment, the stirring mechanism includes a vertical stirring shaft 8 and stirring blades 16. The stirring shaft 8 extends into the storage tank, and its top end passes through the tank cover 5. The stirring shaft 8 is rotatably connected to the tank cover 5 via bearings. A motor 6 for driving the stirring shaft 8 is provided on the outside of the storage tank. Specifically, the motor 6 is fixed to the tank cover 5 by bolts. A drive gear 7 is coaxially fixed to the output shaft of the motor 6 via a key, and a driven gear 9 is coaxially fixed to the stirring shaft 8 via a key. The drive gear 7 and the driven gear 9 mesh, so the motor 6 drives the drive gear 7 to rotate, the drive gear 7 drives the driven gear 9 to rotate, and the driven gear 9 drives the stirring shaft 8 to rotate.

[0034] The stirring blade 16 and the stirring shaft 8 are fixedly connected. Figures 3-4As shown, in this embodiment, there are four stirring blades 16. Each stirring blade 16 has a horizontal discharge channel 15, three vertical intermediate channels 21, and a horizontal return channel 17. The intermediate channels 21 connect the discharge channel 15 and the return channel 17, and the three vertical intermediate channels 21 are arranged in parallel. Figure 4 As shown, the apertures of the three intermediate channels 21 on each stirring blade 16 are different. The aperture of the intermediate channel 21 closest to the stirring shaft 8 is the smallest, while the aperture of the intermediate channel 21 located at the end of the stirring blade 16 away from the stirring shaft 8 is the largest.

[0035] Combination Figures 3-5 As shown, in this embodiment, a feed trough 19 is provided at the top of the stirring shaft 8. The feed trough 19 is circular and coaxially arranged with the stirring shaft 8. A discharge channel 20 is provided on the stirring shaft 8. The discharge channel 20 is located below the feed trough 19 and is arranged axially along the stirring shaft 8. The top of the discharge channel 20 extends to the feed trough 19, and the bottom of the discharge channel 20 extends to the bottom of the stirring shaft 8. A sealing block 18 is welded to the bottom of the stirring shaft 8, and the sealing block 18 seals the bottom of the discharge channel 20. In this embodiment, the diameter of the feed trough 19 is larger than the diameter of the discharge channel 20. A material cylinder 14 is welded into the feed trough 19. The material cylinder 14 and the discharge channel 20 are coaxially arranged and connected. The top of the material cylinder 14 extends to the outside of the top of the stirring shaft 8. The material cylinder 14 separates the discharge channel 20 from the feed trough 19, so that the feed trough 19 and the discharge channel 20 are not connected to each other.

[0036] In this embodiment, the discharge channel 15 and the feed trough 19 are connected; the return channel 17 and the space inside the sealing block are connected, thereby realizing the bottom connection between the return channel 17 and the discharge channel 20.

[0037] Combination Figure 1 , Figure 2 As shown, a first rotating head 10 (bottle cap-shaped) is rotatably mounted on the top of the stirring shaft 8. The top of the first rotating head 10 has a hole for the material cylinder 14 to extend out. The first rotating head 10 is fitted and covers the top of the stirring shaft 8 (the inner wall and bottom of the first rotating head 10 are provided with sealing rings). The inner diameter of the first rotating head 10 is equal to the diameter of the stirring shaft 8. The top of the first rotating head 10 and the stirring shaft 8 are rotatably connected. A feed nozzle 11 is connected to the first rotating head 10. The feed nozzle 11 is connected to a heating box (not shown) outside the storage tank through a hose. The heating box contains a heating medium, which can be heated water, heated oil, or steam. The heating box is equipped with a heating wire, which can heat the heating medium.

[0038] The top of the material cylinder 14 is provided with a second rotating head 12 (bottle cap shaped). Since the top of the material cylinder 14 is located above the top of the stirring shaft 8, the second rotating head 12 is located above the first rotating head 10. The second rotating head 12 is fitted and covers the top of the material cylinder 14 (the inner wall and bottom of the second rotating head 12 are provided with sealing rings). The inner diameter of the second rotating head 12 is equal to the diameter of the material cylinder 14. The second rotating head 12 is connected to a discharge nozzle 13, which is connected to the heating box.

[0039] The specific implementation process is as follows: The storage tank contains graphene slurry. The stirring shaft 8 and stirring blades 16 are inserted into the graphene slurry. The motor 6 drives the drive gear 7 to rotate, the drive gear 7 drives the driven gear 9 to rotate, the driven gear 9 drives the stirring shaft 8 to rotate, and the stirring shaft 8 drives the stirring blades 16 to rotate together, thereby realizing the stirring of the graphene slurry in the storage tank.

[0040] Before or during mixing, the heating medium in the heating tank is pumped into the feed nozzle 11. The heating medium enters the first rotating head 10 through the feed nozzle 11 and then into the feed trough 19 in the gap between the stirring shaft 8 and the material cylinder 14. Figure 4 As shown, the heating medium entering the feed trough 19 flows into the four discharge channels 15. Since the intermediate channel 21 connects the discharge channel 15 and the return channel 17, the heating medium enters the multiple intermediate channels 21 from the discharge channel 15 and flows downward along the intermediate channels 21. The heating medium flows downward from the intermediate channels 21 into the return channel 17. The heating medium in the multiple return channels 17 enters the discharge channel 20 along the return channel 17 and moves upward along the discharge channel 20, finally entering the material cylinder 14 and flowing upward along the material cylinder 14. The heating medium enters the second rotating head 12 and flows out from the discharge nozzle 13 on the second rotating head 12. Finally, the liquid returns to the heating box. After the heating box heats the heating medium, it is pumped back into the feed nozzle 11 by the pump. The heating medium enters the stirring blade again through the feed trough 19, thus circulating.

[0041] In this way, heating medium continuously passes through the discharge channel 15, the intermediate channel 21, and the return channel 17 on the stirring blade 16. The heating medium heats the stirring blade, and the stirring blade 16 heats the graphene slurry. This solves the problem of poor fluidity of graphene slurry at low temperatures, improves the fluidity of graphene slurry, helps to reduce stirring resistance, and improves the stirring effect.
