Description

Technical Field

[0001] The utility model provides a graphite powder purification device for high-temperature purification equipment, belonging to the technical field of carbon-based material production equipment. Background Art

[0002] When high-temperature purification equipment is used to purify graphite powder, the graphite powder needs to be placed in a purification device. In order to increase the loading capacity of the purification device, the height of a purification device is generally set to 1000mm. In addition, in order to reduce the manufacturing cost of the purification device, the outer cylinder and the inner cylinder of the purification device are set to a coaxial hollow cylindrical structure. The outer cylinder is divided into an upper outer cylinder a and a lower outer cylinder b, and the inner cylinder is divided into an upper inner cylinder c and a lower inner cylinder d. The upper outer cylinder a and the lower outer cylinder b are coaxially arranged and interpenetrate each other, the upper inner cylinder c and the lower inner cylinder d are coaxially arranged and interpenetrate each other, and the lower outer cylinder b and the lower inner cylinder d are both threadedly connected to the bottom plate e. When in use, the graphite powder to be purified is placed between the inner cylinder and the outer cylinder. After the process gas is introduced, the gas enters between the inner cylinder and the outer cylinder through the air holes evenly distributed on the inner cylinder, and reacts with the impurities in the graphite powder to be purified to purify the graphite powder. However, in conventional purification devices, the upper outer cylinder a and the lower outer cylinder b are connected by threads, the upper inner cylinder c and the lower inner cylinder d are connected by threads, the lower inner cylinder d and the bottom plate e are connected by threads, and the lower outer cylinder b and the bottom plate e are connected by threads. When the graphite powder is poured out of the purification device after purification, the inner cylinder and the outer cylinder are subjected to large forces due to the effects of the graphite powder and their own gravity. After long-term use, the connecting threads are damaged, thereby shortening the service life of the purification device. Figures 1 to 2 shown.

[0003] In addition, due to the different particle sizes of graphite powder, some small-sized graphite particles leak through the vent holes on the inner cylinder to the outside of the purification device, affecting the stability of the high-temperature purification equipment. Utility Model Content

[0004] In order to solve the technical problems that the inner cylinder and the outer cylinder of the graphite powder purification device of high-temperature purification equipment are subjected to large forces, thereby affecting the service life of the purification device, and the graphite powder penetrates into the outside of the purification device, thereby affecting the stability of the high-temperature purification equipment, the utility model proposes a graphite powder purification device of high-temperature purification equipment, and the purpose is to extend the service life of the purification device and prevent graphite powder from penetrating into the outside of the purification device by improving the hardware structure of the graphite powder purification device.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a high-temperature purification equipment graphite powder purification device, comprising a first purification component and a second purification component, wherein the first purification component and the second purification component are both hollow structures;

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this invention based on specific circumstances.

[0034] like Figures 1 to 8 As shown, the utility model provides a high-temperature purification equipment graphite powder purification device, including a first purification component 1 and a second purification component 2. The first purification component 1 and the second purification component 2 are both hollow structures. One end of the first purification component 1 is provided with a first top cover 3, and the other end of the first purification component 1 is provided with a first bottom plate 4. One end of the second purification component 2 is provided with a second top cover 5, and the other end of the second purification component 2 is provided with a second bottom plate 6. The first bottom plate 4 and the second top cover 5 are detachably connected.

[0035] Specifically, the first purification component 1 comprises a first inner cylinder 7 and a first outer cylinder 8. The first inner cylinder 7 is nested within the first outer cylinder 8, i.e., the first inner cylinder 7 and the first outer cylinder 8 are coaxially arranged. A first gap is left between the sidewalls of the first inner cylinder 7 and the sidewalls of the first outer cylinder 8. The first gap and the first bottom plate 4 form a first chamber for accommodating graphite powder 16. The second purification component 2 comprises a second inner cylinder 9 and a second outer cylinder 10. The second inner cylinder 9 is nested within the second outer cylinder 10, i.e., the second inner cylinder 9 and the second outer cylinder 10 are coaxially arranged. A second gap is left between the sidewalls of the second inner cylinder 9 and the sidewalls of the second outer cylinder 10. The second gap and the second bottom plate 6 form a second chamber for accommodating graphite powder 16. Third vents 19 are provided in both the first inner cylinder 7 and the second inner cylinder 9 to facilitate the entry of process gas into the gap through the third vents 19, allowing the process gas to react with impurities in the graphite powder 16, thereby purifying the graphite powder 16. One end of the first inner tube 7 and one end of the first outer tube 8 are both threadedly connected to the first base plate 4, and the other ends of the first inner tube 7 and the other ends of the first outer tube 8 are both threadedly connected to the first top cover 3. One end of the second inner tube 9 and one end of the second outer tube 10 are both threadedly connected to the second base plate 6, and the other ends of the second inner tube 9 and the other ends of the second outer tube 10 are both threadedly connected to the second top cover 5. The second top cover 5 is provided with a positioning groove 13, which is adapted to the first base plate 4. The first base plate 4 is detachably connected to the positioning groove 13, realizing a detachable connection between the first purification component 1 and the second purification component 2. In this embodiment, the height of the first purification component 1 and the second purification component 2 is 500 mm.

[0036] A first through-hole is defined in the first bottom plate 4, and a second through-hole 11 is defined in the second top cover 5. The first through-hole and the second through-hole 11 are coaxially arranged, and the first purification component 1 and the second purification component 2 are interconnected through the first through-hole and the second through-hole 11. Specifically, the first inner cylinder 7, the second inner cylinder 9, and the first through-hole are coaxially arranged, and the process gas introduced into the graphite powder purification device of the present invention can sequentially pass through the second inner cylinder 9, the second through-hole 11, the first through-hole, and the first inner cylinder 7.

[0037] A positioning device is provided within the second inner tube 9. The positioning device is fixedly connected to the side of the second inner tube 9 near the second base plate 6, that is, to the bottom of the second inner tube 9. A leak-proof component 14 is provided on the positioning device, which allows gas to pass through. Specifically, the positioning device includes a first positioning ring 17 and a second positioning ring 18, which are threadedly connected to the second inner tube 9 and axially positioned by a positioning stop on the second inner tube 9. The leak-proof component 14 is fixed between the first and second positioning rings 17, 18 to prevent graphite powder 16 of varying particle sizes from leaking out of the purification device, ensuring the stability of the high-temperature purification equipment while ensuring that process gas can flow smoothly into the second inner tube 9 and the first inner tube 7. In this embodiment, the leak-proof component 14 is a leak-proof felt. Those skilled in the art may also adapt the leak-proof component 14 to any desired configuration, as long as it ensures that process gas can pass through the leak-proof component 14, prevents graphite powder 16 of varying particle sizes from leaking out of the purification device, and ensures smooth operation of the purification process. A leak-proof component 14 may also be fixed in the first inner tube 7 .

[0038] When using the graphite powder purification device of the present invention for purification operations, the graphite powder 16 to be purified is placed in the first chamber and the second chamber. After the process gas is introduced, the process gas enters the second inner cylinder 9 and the first inner cylinder 7 in turn, and enters the first chamber and the second chamber from the third air vents 19 evenly distributed on the second inner cylinder 9 and the first inner cylinder 7 to purify the graphite powder 16. Since a leak-proof felt component is built into the second purification component 2 and is fixed by the first positioning ring 17 and the second positioning ring 18, graphite powder 16 of different particle sizes can be prevented from leaking to the outside of the purification device through the third air vents 19, thereby ensuring the stability of the high-temperature purification equipment and ensuring that the process gas can smoothly enter the second inner cylinder 9 and the first inner cylinder 7. When pouring out the graphite powder 16 after purification, since the first purification component 1 and the second purification component 2 are detachably connected, the first bottom plate 4 of the first purification component 1 is removed from the positioning groove 13 of the second top plate, and the purified graphite powder 16 in the first purification component 1 and the second purification component 2 are poured out respectively. At this time, the force strength at the threaded connection is greatly reduced compared with the traditional integrated purification device, making the connecting thread less likely to be damaged, thereby increasing the service life of the graphite powder purification device.
