[0034] Next, refer to Figures 1 to 3 Describe a charge loading device for a graphitization furnace and a graphitization furnace according to an embodiment of the present invention.

[0035] The charge loading device for a graphitization furnace according to the first aspect embodiment of the present invention, as Figures 1 to 3 shown, includes a blanking pipe 100, a charging box 200, a negative pressure mechanism 300, and a vibrating compaction mechanism 400.

[0036] Among them, the blanking pipe 100 has a feed end 101 and a discharge end 102. There can be at least two feed ends 101 which are connected to the top of the discharge end 102, and the feed end 101 is used to connect to the discharge port of the graphitization furnace. The shape of the discharge end 102 of the blanking pipe 100 can be various according to the shape of the loading box 200. For example, it can be circular or square. When used for charging the crucible of the Acheson graphitization furnace, the discharge end 102 of the blanking pipe 100 can be circular. When used for charging the graphite box of the box-type graphitization furnace, the discharge end 102 of the blanking pipe 100 can be square.

[0037] The loading box 200 is connected to the discharge end 102. The loading box 200 is used to load graphite powder, and the shape of the loading box 200 can be various, such as circular, square or other suitable shapes.

[0038] The negative pressure mechanism 300 is connected to the loading box 200 and / or the blanking pipe 100. During the loading process, the negative pressure mechanism 300 is started, and the negative pressure mechanism 300 provides a negative pressure environment to the inside of the loading box 200, and indirectly provides a negative pressure environment to the inside of the blanking pipe 100, so that a slightly negative pressure is maintained inside the loading box 200 and the blanking pipe 100.

[0039] The compaction mechanism 400 includes a lifting part 401 and a compaction part 402. The lifting part 401 can be an oil cylinder, a cylinder, an electric push rod, a motor screw mechanism or other suitable structures that can control the lifting of the compaction part 402. The compaction part 402 is connected to the lifting part 401. The lifting part 401 is used to drive the compaction part 402 to lift and lower. During the descending process of the compaction part 402, it can extend into the loading box 200 to compact the powder inside the loading box 200.

[0040] In the present utility model, the feed end 101 of the blanking pipe 100 is connected to the discharge port of the graphitization furnace, and the loading box 200 is connected to the discharge end 102 of the blanking pipe 100. The graphite powder produced by the graphitization furnace enters the loading box 200 through the blanking pipe 100 to achieve loading. During the loading process, the negative pressure mechanism 300 is started. The negative pressure mechanism 300 provides a negative pressure environment to the inside of the loading box 200, and indirectly provides a negative pressure environment to the inside of the blanking pipe 100, so that a slightly negative pressure is maintained in the loading box 200 and the blanking pipe 100, thereby being able to reduce the generation of dust and avoid excessive dust affecting the physical health of the staff and the reliability of the operation of the workshop equipment. In addition, during the loading process, the lifting part 401 of the compaction mechanism 400 drives the compaction part 402 to reciprocate up and down. The compaction part 402 can extend into the loading box 200 to compact the powder inside the loading box 200, so that the loading is more uniform and compact, and the loading quality is better.

[0041] In some embodiments of the present utility model, such as Figure 1 and Figure 3As shown, the compaction part 402 includes a plurality of compaction rods 403 arranged side by side, and the compaction rods 403 extend vertically. For example, nine compaction parts 402 can be provided, and the compaction parts 402 can be arranged in a matrix. In this embodiment, the compaction part 402 includes a plurality of compaction rods 403 arranged side by side. With such an arrangement, the effect of compacting the powder in the charging box 200 is better, so that the charging is more uniform and compact, and the charging quality is better.

[0042] In some embodiments of the present utility model, as Figure 1 and Figure 3 shown, the lifting part 401 is located above the discharge end 102. A plurality of openings are provided at the top of the discharge end 102. The compaction mechanism 400 further includes a plurality of compaction sleeves 404. The plurality of compaction sleeves 404 are located in the discharge end 102. The top of the tube wall of the compaction sleeve 404 is connected to the edge of the opening, and the compaction rod 403 passes through the compaction sleeve 404. For example, the number of compaction sleeves 404 is the same as the number of compaction rods 403 and corresponds to the compaction rods 403 one by one. The compaction sleeve 404 penetrates vertically, and the top of the tube wall of the compaction sleeve 404 is connected to the edge of the opening.

[0043] In this embodiment, the compaction sleeve 404 is provided. The compaction sleeve 404 is used to separate the blanking space in the discharge end 102 and the moving space of the compaction rod 403. In this way, not only can the adhesion of the compaction rod 403 to the powder be reduced, but also the discharge of dust from the gap between the compaction rod 403 and the discharge end 102 can be reduced, so that the generation of dust can be further reduced, and the excessive dust can be further avoided from affecting the physical health of the staff and the reliability of the operation of the workshop equipment.

[0044] In some embodiments of the present utility model, as Figure 1 shown, the bottom of the compaction sleeve 404 extends into the charging box 200. With such an arrangement, not only can the adhesion of the compaction rod 403 to the powder be further reduced, but also the compaction sleeve 404 is relatively long, which can reduce the discharge of dust from the compaction sleeve 404, and the dust prevention effect is better.

[0045] In some embodiments of the present utility model, as Figure 1 shown, there are at least two feeding ends 101, and the feeding ends 101 are connected to the top of the outer side wall of the discharge end 102. There are at least two feeding ends 101, so that they can be connected to the plurality of discharge ports of the graphitization furnace or the discharge ports of a plurality of graphitization furnaces, so that the discharging is more convenient, faster, and the applicable range is wider. Moreover, the feeding ends 101 are connected to the top of the outer side wall of the discharge end 102, which can avoid interference between the feeding ends 101 and the compaction mechanism 400.

[0046] In some embodiments of the present utility model, as Figure 1As shown, the negative pressure mechanism 300 includes a negative pressure sleeve 301 and a negative pressure generator. The negative pressure sleeve 301 is sleeved outside the material discharging pipe 100. The bottom of the negative pressure sleeve 301 is hermetically connected to the side wall of the loading box 200. A negative pressure channel 302 is formed between the negative pressure sleeve 301 and the material discharging pipe 100. The negative pressure generator is communicated with the negative pressure channel 302 to provide negative pressure to the negative pressure channel 302. The negative pressure generator can be a negative pressure fan or a vacuum negative pressure machine, etc. When the negative pressure generator is started, the negative pressure generator can provide negative pressure to the negative pressure channel 302, thereby indirectly forming negative pressure in the loading box 200 and the material discharging pipe 100, and further reducing the generation of dust, avoiding excessive dust from affecting the health of the staff and the reliability of the operation of the workshop equipment.

[0047] In this embodiment, the negative pressure sleeve 301 is sleeved outside the material discharging pipe 100 and a negative pressure channel 302 is formed between them. It not only has a simple structure but also is convenient to install. In addition, the effect of forming negative pressure is better.

[0048] In some embodiments of the present utility model, such as Figure 1 As shown, the bottom of the negative pressure sleeve 301 extends into the loading box 200, and a sealing structure 500 is provided between the bottom of the negative pressure sleeve 301 and the side wall of the loading box 200. The sealing structure 500 surrounds the negative pressure sleeve 301. By setting the sealing structure 500, the sealing performance between the bottom of the negative pressure sleeve 301 and the side wall of the loading box 200 can be better, reducing the discharge of dust from between the bottom of the negative pressure sleeve 301 and the side wall of the loading box 200, and further reducing the generation of dust, thereby further avoiding excessive dust from affecting the health of the staff and the reliability of the operation of the workshop equipment.

[0049] In some embodiments of the present utility model, the sealing structure 500 is set as a sealing rubber strip or a brush-type sealing structure. The sealing rubber strip and the brush-type sealing structure have good sealing performance, are convenient to set, and have a long service life, and are both relatively preferred sealing structures 500.

[0050] It should be noted that both the sealing rubber strip and the brush-type sealing structure are relatively common sealing structures 500, and their structures and working principles will not be elaborated here. The sealing structure 500 can also be other suitable structures for sealing, which will not be elaborated here.

[0051] In some embodiments of the present utility model, such as Figure 2As shown, the bottom of the discharge end 102 is lower than the bottom of the negative pressure sleeve 301. An annular partition 103 is provided on the outer side wall of the bottom of the discharge end 102. The annular partition 103 is located below the negative pressure sleeve 301 and forms a negative pressure suction port 303 between the annular partition 103 and the bottom of the negative pressure sleeve 301. The annular partition 103 can extend along the circumference of the discharge end 102 and surround the discharge end 102. By providing the annular partition 103, the annular partition 103 can play a certain blocking effect, and can reduce the waste of powder caused by the powder entering the negative pressure channel 302 and the negative pressure generator through the negative pressure suction port 303.

[0052] The graphitization furnace according to the second aspect embodiment of the present invention includes the graphitization furnace charging device of the first aspect embodiment described above.

[0053] According to the graphitization furnace of the embodiment of the present invention, by adopting the graphitization furnace charging device of the first aspect embodiment of the present invention, during the charging process, the negative pressure mechanism 300 is started, and the negative pressure mechanism 300 provides a negative pressure environment for the charging box 200, and indirectly provides a negative pressure environment for the feeding pipe 100, so that the charging box 200 and the feeding pipe 100 maintain a slightly negative pressure, thereby reducing the generation of dust and avoiding excessive dust from affecting the physical health of the staff and the reliability of the operation of the workshop equipment. In addition, during the charging process, the lifting part 401 of the compaction mechanism 400 drives the compaction part 402 to reciprocate up and down, and the compaction part 402 can extend into the charging box 200 to compact the powder in the charging box 200, so that the charging is more uniform and compact, and the charging quality is better.

[0054] It should be noted that since the graphitization furnace can adopt all the technical solutions of the graphitization furnace charging device of the first aspect embodiment described above, it at least has all the beneficial effects brought by the technical solutions of the first aspect embodiment described above.
