Description

TECHNICAL FIELD

[0001] The utility model relates to drying equipment technical field, concretely is a kind of high-efficiency energy-saving drying equipment of high-purity carbon nanotube or graphite powder. BACKGROUND

[0002] Due to the nanometer size effect and special structure of high-purity carbon nanotube, there is strong van der waals force between high-purity carbon nanotubes, which is easy to agglomerate. Graphite powder has high surface energy. During the drying process, as the water gradually evaporates, the intermolecular force on the surface of graphite particles increases. In order to reduce the surface energy, the particles will come close to each other and combine together, resulting in the occurrence of agglomeration. The agglomeration of high-purity carbon nanotubes or graphite powder during the drying process not only affects the drying effect, but also increases the drying time, resulting in the long-term continuous output of the drying heat source, thereby increasing the drying cost of high-purity carbon nanotubes or graphite powder.

[0003] Therefore, there is an urgent need for a high-efficiency energy-saving drying equipment for high-purity carbon nanotubes or graphite powder to solve the above problems. SUMMARY

[0004] The utility model aims at providing a kind of high-efficiency energy-saving drying equipment for high-purity carbon nanotubes or graphite powder to solve the problem of agglomeration of high-purity carbon nanotubes or graphite powder during the drying process proposed in the above background.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0016] like Figures 1-4 The image shown is a schematic diagram of an embodiment of a high-efficiency and energy-saving drying device for high-purity carbon nanotubes or graphite powder provided by this utility model:

[0017] A high-efficiency and energy-saving drying device for high-purity carbon nanotubes or graphite powder includes a working box 1, two support rings 2 disposed inside the working box 1, and a drying cylinder 3 rotatably connected to the two support rings 2. The inner wall of the drying cylinder 3 is fixedly connected with multiple material plates 4. The working box 1 is provided with a supply component for supplying heat to the drying cylinder 3 and a circulation component for recycling the heat source. The drying cylinder 3 is provided with a dispersion component for dispersing high-purity carbon nanotubes or graphite powder. The working box 1 is also provided with a rotating component for driving the drying cylinder 3 to rotate and a driving component disposed on the rotating component for driving the dispersion component.

[0018] The dispersing component includes a mounting ring 502 rotatably connected to the opening end of the drying cylinder 3 and a plurality of connecting plates 501. The two ends of the connecting plates 501 are respectively connected to the inner wall of the working box 1 and the outer wall of the mounting ring 502. A protective door 504 is hinged to the side of the mounting ring 502 away from the drying cylinder 3, and a mesh plate 503 is connected to the other side of the mounting ring 502 through a telescopic component.

[0019] It should be noted that, through the setting of the dispersion component, and with the cooperation of the telescopic component and the drive component, while rotating and drying high-purity carbon nanotubes or graphite powder, the high-purity carbon nanotubes or graphite powder are continuously sieved. This not only continuously separates particles that are in contact or close together, preventing them from forming large agglomerates, but also continuously disperses accumulated particles, preventing local accumulation. This reduces the probability of agglomeration of high-purity carbon nanotubes or graphite powder during the drying process, thereby further enhancing the drying effect of high-purity carbon nanotubes or graphite powder while reducing the continuous output time of the heat source. This improves the drying efficiency of high-purity carbon nanotubes or graphite powder while reducing energy consumption, achieving energy-saving effects. At the same time, through the setting of the circulation component, hot air can be reused, further improving the energy-saving effect of the high-purity carbon nanotubes or graphite powder drying process.

[0020] The telescopic assembly includes two fixed plates 601 fixedly connected to the inner wall of the mounting ring 502. The two fixed plates 601 are symmetrically arranged, and each of the two fixed plates 601 is fixedly connected to a T-shaped rod 602 on the side of the mesh plate 503. The two sides of the mesh plate 503 are slidably connected to the corresponding T-shaped rods 602. A spring 603 is also sleeved on the T-shaped rod 602, and the two ends of the spring 603 are respectively connected to the mesh plate 503 and the fixed plate 601.

[0021] It should be noted here that the telescopic components are designed to provide support, guidance, and reset for the stencil 503.

[0022] The rotating assembly includes a rotating tube 701 rotatably connected to the side of the working box 1 away from the protective door 504. One end of the rotating tube 701 is connected to the drying cylinder 3. A gear ring 702 is fixedly connected to the outer peripheral wall of the rotating tube 701. An L-shaped plate 703 is fixedly connected to one side of the working box 1. A gear 704 is connected to the L-shaped plate 703 through a rotating shaft. The gear 704 and the gear ring 702 are meshed with each other. A motor 705 is provided on the side of the L-shaped plate 703 away from the working box 1. The output end of the motor 705 is connected to the rotating shaft.

[0023] It should be noted here that the rotating component is used to drive the drying drum 3 to rotate.

[0024] The driving assembly includes a driving rod 801 slidably connected to the side of the drying cylinder 3 near the rotating tube 701. One end of the driving rod 801 is connected to the mesh plate 503. The driving rod 801 and the rotating tube 701 are concentrically arranged. A driving plate 802 is fixedly connected to the outer wall of the driving rod 801. A plurality of triangular plates 803 are fixedly connected to the end of the rotating tube 701 near the driving plate 802.

[0025] It should be noted here that the drive component is configured to drive the mesh plate 503 to reciprocate within the drying drum 3.

[0026] The working principle of this embodiment one is roughly as follows:

[0027] When drying high-purity carbon nanotubes or graphite powder, first open the protective door 504, put the high-purity carbon nanotubes or graphite powder into the drying cylinder 3, then close the protective door 504, start the motor 705, drive the gear 704 on the rotating shaft to rotate, and during the rotation of the gear 704, through the meshing transmission action of the gear 704 and the gear ring 702, drive the rotating tube 701 to rotate, and then drive the drying cylinder 3 to rotate.

[0028] During the rotation of the drying cylinder 3, the conveyor plates 4 will rotate synchronously, carrying high-purity carbon nanotubes or graphite powder to the upper side of the drying cylinder 3. Under gravity, these materials will fall onto the mesh plate 503. Simultaneously, the rotation of the rotating tube 701 will also drive the triangular plate 803 to rotate. When the triangular plate 803 comes into contact with the drive plate 802, the interaction force and the guiding action of the telescopic components will push the drive plate 802 away from the rotating tube 701, thus moving the mesh plate 503 away from the protective door 504. When the triangular plate 803 passes the drive plate 802, the elasticity of the telescopic components will cause the mesh plate 503 to move closer to the protective door 504, thereby moving the high-purity carbon nanotubes or graphite powder onto the mesh plate 503. 1. During continuous rotation, the triangular plate 803 will reciprocate against the drive plate 802, thereby pushing the mesh plate 503 to reciprocate within the drying cylinder 3. This is used to sieve high-purity carbon nanotubes or graphite powder. It can not only continuously separate particles that are in contact or close together, preventing them from forming large agglomerates, but also continuously disperse accumulated particles to prevent local accumulation. This reduces the probability of high-purity carbon nanotubes or graphite powder agglomerating during the drying process. This further enhances the drying effect of high-purity carbon nanotubes or graphite powder while reducing the continuous output time of the heat source. Thus, while improving the drying efficiency of high-purity carbon nanotubes or graphite powder, it reduces energy consumption and achieves energy-saving effects.

[0029] Example 2: A high-efficiency and energy-saving drying device for high-purity carbon nanotubes or graphite powder

[0030] like Figures 2-4 As shown, this second embodiment further illustrates the concept based on the first embodiment:

[0031] The supply assembly includes a hot air blower 901 located on one side of the working box 1. The hot air blower 901 has a supply hose 902 at its air outlet end. The other end of the supply hose 902 is connected to the drive rod 801 via a universal ball joint. The drive rod 801 is provided with multiple air outlet pipes 903 on the outer wall inside the drying cylinder 3. All multiple air outlet pipes 903 are connected to the supply hose 902. Each air outlet pipe 903 is also provided with multiple nozzles 904 on the side near the mesh plate 503.

[0032] It should be noted that the supply component is used to continuously deliver hot air into the drying cylinder 3, thereby achieving the drying of high-purity carbon nanotubes or graphite powder.

[0033] Furthermore, if the hot air delivery pressure of the hot air blower 901 is greater than or equal to the air outlet pressure of each nozzle 904, then the hot air can be evenly sprayed out from each nozzle 904.

[0034] Please see Figure 2 and Figure 3The circulation assembly includes a circulation hose 1001 disposed on the side of the protective door 504 away from the drying cylinder 3. One end of the circulation hose 1001 is connected to the side wall of the air inlet pipe of the hot air blower 901, and the other end of the circulation hose 1001 is located inside the drying cylinder 3 and is connected to a circulation cover 1002.

[0035] It should be noted that by setting up the circulation component, the hot air inside the drying cylinder 3 is re-introduced into the hot air blower 901 through the circulation cover 1002 at one end of the circulation hose 1001, thereby realizing the circulation of hot air inside the drying cylinder 3 and the reuse of hot air, thus improving the energy-saving effect of the drying process of high-purity carbon nanotubes or graphite powder.

[0036] Furthermore, a dehumidifier can be installed on the outer wall of the circulation hose 1001 to dehumidify the circulating hot air, thereby ensuring the dryness of the hot air circulating into the hot air blower 901.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
