Description

Technical Field

[0001] This utility model relates to the field of graphite purification technology, specifically a graphite purification device. Background Technology

[0002] Graphite, as a carbon-carbon composite material, has a metallic luster, a relatively soft and slippery texture, stable chemical properties, corrosion resistance, and does not easily react with acids, alkalis, and other agents. Graphite requires purification during its manufacturing process, thus necessitating the use of purification equipment.

[0003] Chinese patent application CN 113428853 A discloses a high-temperature graphite purification device, including a multi-stage temperature-controlled vortex contact reaction device, a vortex-action solid-vapor separation device, a waste heat recovery device, a graphite cooling and purity maintenance device, and a primary feed pipe for mixed raw materials. This invention belongs to the field of graphite purification technology, specifically providing a device without complex or rigid mechanical structures. It achieves uniform contact between graphite and high-temperature gas through a spirally stacked feed pipe and heating pipe. The multi-stage temperature-controlled vortex contact reaction device allows for more precise temperature control, and the batch feeding of fuel and hot air improves nitrogen oxide control, reducing the difficulty of denitrification. Heat energy can be recycled through the waste heat recovery device, protecting the gas and saving costs. Utilizing the characteristics of a heat pump, while cooling impurities and graphite, the generated heat can heat the combustion air, resulting in high hot air temperature, stable combustion, complete combustion, and further fuel savings in this high-temperature graphite purification device.

[0004] In existing purification devices, graphite is usually purified by high-temperature heating. However, this process fails to ensure uniform heating of the graphite particles, resulting in poor purification uniformity and affecting the purification quality. Therefore, a graphite purification device is proposed to address this problem. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a graphite purification device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a graphite purification device, including a frame, on which a heating furnace is mounted. A control panel is mounted on the outer wall of the heating furnace, a fixing frame is mounted on the inner wall of the heating furnace, and a guide plate is mounted on the fixing frame. A heating groove is formed between the guide plate and the inner wall of the heating furnace. A first heating plate is installed inside the side wall of the heating furnace, and a second heating plate is installed inside the guide plate. The first and second heating plates are connected to the control panel through an internal circuit. A rotating rod is rotatably mounted on the top plate of the heating furnace. A material guide groove is opened inside the rotating rod, and a spiral blade is mounted on the rotating rod. A first gear is fixedly sleeved around the rotating rod. A drive motor is mounted on the top plate of the heating furnace via a base. The output shaft of the drive motor... A second gear is installed on the top plate of the furnace, which is rotatably connected to the top plate of the furnace. The second gear meshes with the first gear. A support frame is installed on the top plate of the furnace, and a storage hopper is installed on the support frame. The storage hopper is rotatably connected to a rotating rod, and a cover is installed on the storage hopper. Graphite particles enter the furnace through the guide chute. The rotating rod drives the spiral blades to rotate, and the spiral blades drive the graphite particles upward. Then, the graphite particles slide downward into the heating groove between the guide plate and the inner wall of the furnace, where they come into contact with the inner wall of the heating groove and are heated evenly. This structure ensures that each graphite particle is heated evenly, achieving stability and uniformity in the heating of the graphite particles, which is beneficial to improving the uniformity of graphite particle purification and the purification quality of the graphite particles.

[0007] Preferably, a gas guide pipe is installed on the side wall of the heating furnace, and the other end of the gas guide pipe is connected to a condenser bottle. The condenser bottle is fixedly connected to the outer wall of the heating furnace. A first discharge pipe is installed on the bottom side of the condenser bottle, and a first valve is installed on the first discharge pipe. A second discharge pipe is installed on the bottom side of the heating furnace, and a second valve is installed on the second discharge pipe. Graphite particles are uniformly heated in the heating furnace, and the moisture contained in the graphite is evaporated by the heating. During this process, water vapor is generated in the heating furnace. The water vapor enters the condenser bottle from the gas guide pipe and is condensed into water droplets, thus treating the water vapor and preventing the condensed water droplets from directly suspending inside the heating furnace. This avoids cleaning the inner wall of the heating furnace and helps improve the cleanliness of the device.

[0008] The advantages of this utility model are:

[0009] 1. This utility model involves graphite particles entering the heating furnace from the feed chute. A rotating rod drives the spiral blades to rotate, which in turn moves the graphite particles upward. The graphite particles then slide downward into the heating trough between the guide plate and the inner wall of the heating furnace, where they come into contact with the inner wall and are heated evenly. This structure ensures that each graphite particle is heated uniformly, achieving stability and uniformity in the heating of the graphite particles. This is beneficial for improving the uniformity of graphite particle purification and thus improving the purification quality of the graphite particles.

[0010] 2. This utility model achieves uniform heating of graphite particles in a heating furnace, causing the moisture contained in the graphite to evaporate. During this process, water vapor is generated in the heating furnace. The water vapor enters the condenser bottle through the gas guide pipe and is condensed into water droplets, thus treating the water vapor and preventing the condensed water droplets from being directly suspended inside the heating furnace. This avoids cleaning the inner wall of the heating furnace and helps improve the cleanliness of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-4 As shown, a graphite purification device includes a stand 1, a heating furnace 2 mounted on the stand 1, a control panel 3 mounted on the outer wall of the heating furnace 2, a fixing frame 4 mounted on the inner wall of the heating furnace 2, a guide plate 5 mounted on the fixing frame 4, a heating groove between the guide plate 5 and the inner wall of the heating furnace 2, a first heating plate 6 mounted inside the side wall of the heating furnace 2, a second heating plate 7 mounted inside the guide plate 5, the first heating plate 6 and the second heating plate 7 being connected to the control panel 3 via internal circuitry, and a rotating rod 8 rotatably mounted on the top plate of the heating furnace 2, with a material guide groove 9 opened inside the rotating rod 8. A spiral blade 10 is installed, and a first gear 11 is fixedly sleeved around the rotating rod 8. A drive motor 12 is mounted on the top plate of the heating furnace 2 via a base. A second gear 13 is mounted on the output shaft of the drive motor 12. The second gear 13 is rotatably connected to the top plate of the heating furnace 2, and the second gear 13 and the first gear 11 mesh with each other. A support frame 14 is mounted on the top plate of the heating furnace 2, and a storage hopper 22 is mounted on the support frame 14. The storage hopper 22 is rotatably connected to the rotating rod 8, and a cover 15 is mounted on the storage hopper 22. During operation, in the existing purification device, during the purification of graphite, ... Graphite is often purified by high-temperature heating. However, this process fails to ensure uniform heating of the graphite particles, resulting in poor purification uniformity and affecting the quality of the purified particles. To address this, graphite particles are poured into a storage hopper 22 and then covered with a cover 15. The particles then enter the heating furnace 2 through a guide chute 9. The drive motor 12 rotates the second gear 13, which in turn drives the first gear 11. The first gear 11 then rotates the rotating rod 8, which in turn rotates the spiral blades 10. The spiral blades 10 then move the graphite particles upwards until they reach a certain point. After reaching the top of the guide plate 5, the graphite particles slide down into the heating groove between the guide plate 5 and the inner wall of the heating furnace 2. The first heating plate 6 and the second heating plate 7 on the guide plate 5 and the inner wall of the heating furnace 2 keep the guide plate 5 and the inner wall of the heating furnace 2 at a high temperature. During the process of the graphite particles sliding down the heating groove, they will come into contact with the inner wall of the heating groove and be heated evenly. This structure can make each graphite particle evenly heated, realize the stability and uniformity of the graphite particle heating, which is beneficial to improving the uniformity of graphite particle purification and improving the purification quality of graphite particles.

[0020] Please see Figure 5As shown, a gas guide pipe 16 is installed on the side wall of the heating furnace 2, and the other end of the gas guide pipe 16 is connected to a condenser bottle 17. The condenser bottle 17 is fixedly connected to the outer wall of the heating furnace 2. A first discharge pipe 18 is installed on the bottom side of the condenser bottle 17, and a first valve 19 is installed on the first discharge pipe 18. A second discharge pipe 20 is installed on the bottom side of the heating furnace 2, and a second valve 21 is installed on the second discharge pipe 20. During operation, in the existing purification device, the condensed water droplets are directly suspended inside the device during the purification process of graphite, which requires cleaning of the inner wall of the device, resulting in poor cleanliness inside the device. By uniformly heating the graphite particles in the heating furnace 2, the water contained in the graphite is evaporated. During this process, water vapor is generated inside the heating furnace 2. The water vapor enters the condenser bottle 17 from the gas guide pipe 16 and is condensed into water droplets, thus treating the water vapor and preventing the condensed water droplets from being directly suspended inside the heating furnace 2, avoiding the need to clean the inner wall of the heating furnace 2, and improving the cleanliness inside the device.

[0021] Working principle: In existing purification devices, graphite is typically purified by high-temperature heating. However, this fails to ensure uniform heating of the graphite particles, resulting in poor purification uniformity and affecting the quality of the purified graphite particles. By pouring graphite particles into the storage hopper 22 and then covering it with the cover 15, the graphite particles enter the heating furnace 2 through the guide chute 9. The drive motor 12 operates, driving the second gear 13 to rotate. The second gear 13 drives the first gear 11 to rotate, which in turn drives the rotating rod 8 to rotate. The rotating rod 8 drives the spiral blades 10 to rotate, causing the graphite particles to move upwards until they reach above the guide plate 5. The graphite particles then slide downwards into the heating groove between the guide plate 5 and the inner wall of the heating furnace 2. The first heating plate 6 and the second heating plate 7 on the guide plate 5 and the inner wall of the heating furnace 2 maintain a high temperature for the graphite particles. As the graphite particles slide down the heating tank, they come into contact with the inner wall of the tank, resulting in uniform heating. This structure ensures that each graphite particle is heated evenly, achieving stability and uniformity in heating. This improves the uniformity of graphite particle purification and enhances the purification quality. In existing purification devices, condensed water droplets are directly suspended inside the device, requiring cleaning of the inner wall and resulting in poor cleanliness. By uniformly heating the graphite particles in the heating furnace 2, the moisture in the graphite evaporates. During this process, water vapor is generated inside the heating furnace 2. The water vapor enters the condenser bottle 17 through the gas guide pipe 16 and is condensed into water droplets. This process treats the water vapor, preventing the condensed water droplets from being directly suspended inside the heating furnace 2 and avoiding the need for cleaning the inner wall, thus improving the cleanliness of the device's interior.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
