[0003] Some large graphitization furnaces require manual feeding, where workers cut open ton bags to allow the material to be thrown into the furnace chamber by gravity; however, this method of feeding can easily cause workers to fall into the furnace chamber, resulting in safety accidents.

[0004] Therefore, how to design a graphitization furnace system and a mobile feeding trolley to replace manual feeding is a key issue.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0024] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0025] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figure 1 , Figure 2 As shown, at least one embodiment provides a graphitization furnace system, including: a graphitization furnace body 1 and several moving platforms 2, wherein the moving platforms 2 are provided with a storage bin 3, a negative pressure generator 4, an annular tubular chain conveyor 5 and a discharge assembly 6.

[0027] Specifically, such as Figure 1 As shown, the graphitization furnace body 1 is provided with multiple furnace cavities 11, and graphite materials can be put into each furnace cavity 11. In order to adapt to different production needs, a mobile platform 2 is independently set on each furnace cavity 11 on the graphitization furnace body 1.

[0028] Specifically, such as Figure 1 As shown, the mobile platform 2 is set on the graphitization furnace body 1 and located above the furnace cavity 11, and can be moved along the length of the furnace cavity 11 by the drive of the driver.

[0029] Specifically, such as Figure 2 As shown, the negative pressure generator 4 is connected to the upper part of the storage silo 3, the middle part of the storage silo 3 is connected to the material pipeline 12, the bottom of the storage silo 3 is connected to the annular tubular chain conveyor 5, and the discharge assembly 6 is connected to the annular tubular chain conveyor 5; that is, the storage silo 3 receives the material conveyed by the positive pressure in the material pipeline 12, and the negative pressure generator 4 reduces the pressure in the storage silo 3. Then the material in the storage silo 3 falls into the annular tubular chain conveyor 5 for conveying and moving in the annular tubular chain conveyor 5 until it is discharged into the furnace cavity 11 from the discharge assembly 6.

[0030] In this embodiment, automated feeding is used instead of manual feeding. The storage silo 3 receives the material conveyed under positive pressure and reduces the pressure through the negative pressure generator 4. Then, the annular tubular chain conveyor 5 receives the material in the storage silo 3 and feeds it into the furnace cavity 11 through the discharge assembly 6. Finally, the movement of the moving platform 2 drives the discharge assembly 6 to feed materials into various areas of the furnace cavity 11. This not only avoids the safety hazards caused by manual feeding but also improves the feeding efficiency.

[0031] like Figure 2 As shown, in some embodiments, a rotary valve 31 is provided on the connecting pipeline between the storage bin 3 and the annular tubular chain conveyor 5.

[0032] In this embodiment, the rotary valve 31 can separate the storage bin 3 from the annular tubular chain conveyor 5, avoiding abnormal feeding due to pressure difference, and at the same time, it can accurately feed the material in a quantitative manner.

[0033] In some embodiments, the annular tubular chain conveyor 5 is provided with a plurality of discharge ports 51; the discharge assembly 6 is connected to each discharge port 51 to guide the material to be discharged into the furnace chamber 11.

[0034] In this embodiment, an on / off valve is provided on the discharge port 51 to control the opening and closing of the discharge port 51.

[0035] like Figure 3 As shown, in some embodiments, the discharge assembly 6 includes: a plurality of transverse adjustment platforms 61; a plurality of guide pipes 62, which are disposed on the corresponding transverse adjustment platforms 61; wherein the upper end of the guide pipe 62 is connected to the corresponding discharge port 51; the transverse adjustment platform 61 is adapted to adjust the spacing of the guide pipes 62.

[0036] Specifically, the lower surface of the transverse adjustment table 61 is provided with a slider, a motor and a gear, and the moving platform 2 is provided with a guide rail and a rack; wherein, the gear and the rack mesh, that is, the transverse adjustment table 61 is driven by the motor to rotate the gear, thereby causing the transverse adjustment table 61 to slide on the guide rail.

[0037] In this embodiment, in order to adapt to different needs, the number and spacing of the baffles in the furnace cavity 11 will be adjusted. Therefore, a transverse adjustment platform 61 is set for each material guide pipe 62 to drive the material guide pipe 62 to move horizontally, so that the material guide pipe 62 can be aligned with the feeding position.

[0038] like Figure 2 As shown, in some embodiments, a pair of roller sets 21 are provided on the lower surface of the mobile platform 2; a corresponding track 13 is provided on the upper surface of the graphitization furnace body 1; wherein the roller sets 21 are arranged on the corresponding track 13.

[0039] In this embodiment, the track 13 is arranged along the length of the furnace cavity 11, thereby guiding the movement of the moving platform 2 so that the discharge assembly 6 can fill the furnace cavity 11 more evenly.

[0040] like Figure 3 As shown, in some embodiments, a pair of drive motors 22 are provided on the mobile platform 2, and a spur gear 23 is provided at the end of the drive motor 22; a corresponding spur rack 14 is provided on the upper surface of the graphitization furnace body 1; wherein, the spur gear 23 meshes with the corresponding spur rack 14.

[0041] In this embodiment, the drive motor 22 can be a servo motor, and the two drive motors 22 rotate synchronously to make the mobile platform 2 move on the track 13.

[0042] like Figure 3 As shown, in some embodiments, a plurality of drag chains 15 are provided on the upper surface of the graphitization furnace body 1; wherein, the material pipe 12 passes through the corresponding drag chain 15.

[0043] In this embodiment, the cable chain 15 can restrict the position of the material pipe 12 to prevent the material pipe 12 from blocking the movement of the mobile platform 2.

[0044] At least one embodiment also provides a mobile feeding trolley 7, applied to a graphitization furnace system, comprising: a mobile platform 2, on which a storage silo 3, a negative pressure generator 4, an annular tubular chain conveyor 5, and a discharge assembly 6 are mounted; wherein the negative pressure generator 4 is connected to the upper part of the storage silo 3, the middle part of the storage silo 3 is connected to the material pipeline 12, the bottom of the storage silo 3 is connected to the annular tubular chain conveyor 5, and the discharge assembly 6 is connected to the annular tubular chain conveyor 5; the storage silo 3 receives material conveyed under positive pressure in the material pipeline 12 and depressurizes the storage silo 3 through the negative pressure generator 4, and is adapted to convey the stored material into the annular tubular chain conveyor 5; the discharge assembly 6 is adapted to discharge the material in the annular tubular chain conveyor 5 into the furnace cavity 11.

[0045] In this embodiment, automated feeding is used instead of manual feeding. The storage silo 3 receives the material conveyed under positive pressure and reduces the pressure through the negative pressure generator 4. Then, the annular tubular chain conveyor 5 receives the material in the storage silo 3 and feeds it into the furnace cavity 11 through the discharge assembly 6. Finally, the movement of the moving platform 2 drives the discharge assembly 6 to feed materials into various areas of the furnace cavity 11. This not only avoids the safety hazards caused by manual feeding but also improves the feeding efficiency.

[0046] In some embodiments, a rotary valve 31 is provided on the connecting pipeline between the storage silo 3 and the annular tubular chain conveyor 5.

[0047] In this embodiment, the rotary valve 31 can separate the storage bin 3 from the annular tubular chain conveyor 5, avoiding abnormal feeding due to pressure difference, and at the same time, it can accurately feed the material in a quantitative manner.

[0048] In some embodiments, the discharge assembly 6 includes: a plurality of transverse adjustment platforms 61; a plurality of guide pipes 62 disposed on the respective transverse adjustment platforms 61; wherein the upper end of the guide pipe 62 is connected to the respective discharge port 51; the transverse adjustment platform 61 is adapted to adjust the spacing of the guide pipes 62.

[0049] In this embodiment, in order to adapt to different needs, the number and spacing of the baffles in the furnace cavity 11 will be adjusted. Therefore, a transverse adjustment platform 61 is set for each material guide pipe 62 to drive the material guide pipe 62 to move horizontally, so that the material guide pipe 62 can be aligned with the feeding position.

[0050] In summary, this graphitization furnace system and mobile feeding trolley adopt an automated feeding method to replace manual feeding. Specifically, the storage silo 3 receives the material conveyed under positive pressure and reduces the pressure through the negative pressure generator 4. Then, the annular tubular chain conveyor 5 receives the material in the storage silo 3 and feeds it into the furnace cavity 11 through the discharge assembly 6. Finally, the movement of the mobile platform 2 drives the discharge assembly 6 to feed materials into various areas within the furnace cavity 11. This not only avoids the safety hazards caused by manual feeding but also improves the feeding efficiency.
