Description

Technical Field

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

[0002] High-temperature graphite purification technology mainly includes two methods: chemical purification and physical purification. Chemical purification includes the alkali-acid method, hydrofluoric acid method, and chlorination roasting method, while physical purification mainly involves the high-temperature method. The high-temperature method involves treating graphite ore at high temperatures, causing impurities to volatilize or decompose at high temperatures, thereby extracting high-purity graphite.

[0003] Traditional purification devices have a small contact area with graphite, which means that heat needs to be transferred from the outer layer of graphite to the inner layer. This results in a longer total heating time for the graphite in the device, which greatly reduces the graphite purification efficiency and is not conducive to the volatilization of impurities.

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figures 1 to 6 As shown, a graphite purification device of the present invention includes a high-temperature furnace 7, an internal heating mechanism 6 and a tilting mechanism. The tilting mechanism is driven to the high-temperature furnace 7. The internal heating mechanism 6 is installed inside the high-temperature furnace 7. An inlet and outlet are provided at one end of the high-temperature furnace 7. A sealing door 5 is removed from the inlet and outlet.

[0029] The internal heating mechanism 6 includes a rotation drive assembly, a first rotating shaft 604, and a plurality of internal heating assemblies. The first rotating shaft 604 is rotatably connected to the interior of the high-temperature furnace 7. A plurality of the internal heating assemblies are arranged alternately on the first rotating shaft 604. The rotation drive assembly is drivenly connected to the first rotating shaft 604.

[0030] The internal heating assembly includes a connecting rod 603, an arc-shaped component 602, a heating element 608, and scrapers 601. The side of the arc-shaped component 602 near the first rotating shaft 604 is connected to the outer surface of the first rotating shaft 604 via the connecting rod 603. Several scrapers 601 are provided on the side of the arc-shaped component 602 near the high-temperature furnace 7. A gap is provided between the arc-shaped component 602 and the inner surface of the high-temperature furnace 7. The scrapers 601 are movably connected to the inner surface of the high-temperature furnace 7. A first cavity 611 is provided inside the arc-shaped component 602. A second cavity 609 is provided inside the connecting rod 603. The first cavity 611 and the second cavity 609 are internally connected. The heating element 608 is laid inside both the first cavity 611 and the second cavity 609.

[0031] The working principle of this utility model is as follows: In actual production and use, when graphite needs to be purified, graphite powder can be fed into the high-temperature furnace 7 through the inlet and outlet. Then, the high-temperature furnace 7 and the heating element 608 are operated, causing the high-temperature furnace 7 to heat the graphite inside. Simultaneously, the heating element 608 heats the connecting rod 603 and the arc-shaped component 602. Part of the graphite adheres to the bottom of the high-temperature furnace 7, allowing the furnace 7 to directly transfer heat to this portion of graphite. Furthermore, this portion of graphite can also contact the arc-shaped component 602, thus... The graphite can be heated on both sides. During heating, the rotation drive assembly can also be operated, which drives several sets of internal heating assemblies to rotate through the first rotating shaft 604. During the rotation of the internal heating assemblies, the remaining graphite falls onto the upper part of the arc-shaped part 602, so that this part of the graphite material can be heated through the connecting rod 603 and the upper part of the arc-shaped part 602. When the scraper 601 moves, it can scrape away the graphite powder attached to the lower surface of the high-temperature furnace 7, so that the high-temperature furnace 7 will not continuously heat the same batch of graphite material.

[0032] Furthermore, the rotation drive assembly includes a first rotation drive component 605, two gears 606, and a fixed base 607. Each gear 606 is rotatably connected to the outside of the other end of the high-temperature furnace 7. One gear 606 is sleeved on the outer surface of the first rotating shaft 604 and fixedly connected to the first rotating shaft 604. The gears 606 mesh with each other. The first rotation drive component 605 is drivenly connected to the other gear 606. The first rotation drive component 605 is detachably connected to the outer surface of the high-temperature furnace 7 through the fixed base 607.

[0033] As can be seen from the above description, when it is necessary to turn the graphite in the high-temperature furnace 7, the first rotation drive 605 can be operated, so that the first rotation drive 605 drives the first rotating shaft 604 to rotate through the gear 606, thereby causing the first rotating shaft 604 to drive several internal heating components to turn the graphite.

[0034] Furthermore, a wiring groove 610 is provided in the middle of the first rotating shaft 604, and the second cavity 609 is connected to the wiring groove 610.

[0035] As can be seen from the above description, the heating element 608 in the first cavity 611 and the second cavity 609 can be better connected to electricity through the wiring groove 610.

[0036] Furthermore, the tilting mechanism includes a base, a bracket 3, a second rotating shaft 9, and a second rotating drive component 2. The upper part of the bracket 3 is sleeved on the outer surface of the high-temperature furnace 7 and is fixedly connected to the outer surface of the high-temperature furnace 7. The lower part of the bracket 3 is rotatably connected to the base through the second rotating shaft 9. The second rotating drive component 2 is drivenly connected to the second rotating shaft 9.

[0037] As can be seen from the above description, when it is necessary to add or unload materials to the high-temperature furnace 7, the second rotation drive 2 can be operated, so that the second rotation drive 2 drives the support 3 to rotate through the second rotating shaft 9, thereby causing the support 3 to drive the high-temperature furnace 7 to rotate, so that the inlet and outlet on the high-temperature furnace 7 can be moved to a suitable position, which facilitates subsequent addition or unloading of materials.

[0038] Furthermore, it also includes a gas inlet pipe 1. The high-temperature furnace 7 has several exhaust ports on its upper part, and a gas inlet pipe 1 is provided on each of the exhaust ports.

[0039] As can be seen from the above description, gases that are beneficial to the decomposition of impurities can be discharged outside the device through the gas inlet pipe 1 for treatment.

[0040] Furthermore, it also includes a filter screen 8, and each of the air intake pipes is provided with a filter screen 8.

[0041] As can be seen from the above description, the filter screen 8 is beneficial for blocking graphite powder and preventing graphite powder from overflowing.

[0042] Furthermore, it also includes a PLC controller, which is electrically connected to the high-temperature furnace 7, the internal heating mechanism 6, and the tilting mechanism, respectively.
