Description

Technical Field

[0001] This utility model relates to the field of graphite crucible production technology, specifically to an automated production line for graphite crucibles used in aluminum alloys. Background Technology

[0002] Graphite crucibles are crucial containers and tools in the production of alloys and graphite anode materials for batteries, finding wide application in related industries. Current graphite crucible production primarily employs a semi-mechanized approach combined with manual handling, utilizing forklifts, overhead cranes, manual assistance, and individual machines to complete the entire workflow. Workers, in coordination with overhead cranes and clamps, handle the hoisting and transfer of all graphite crucibles and saggers, resulting in high labor intensity and significant safety risks. Cleaning the filler is mainly done manually, generating dust that significantly impacts worker health. The effectiveness of manual filler cleaning is difficult to guarantee, affecting the quality of the finished crucibles. Because each step requires personnel to coordinate with overhead cranes and clamps for transfer, production efficiency is low. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides an automated production line for graphite crucibles used in aluminum alloys. By arranging a complete set of automated equipment, the automatic production of graphite crucibles is achieved, thereby improving production efficiency and reducing safety risks and manual labor intensity.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0018] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments. Example

[0019] like Figures 1 to 4 As shown, this utility model provides an automatic production line for graphite crucibles used in aluminum alloys, including a raw crucible transport unit, a processing unit, a finished product transport unit, and a flatbed trolley transport unit. The processing unit includes a sagger conveyor 7, with a sagger cover conveyor 10 on one side. The inlet end of the sagger conveyor 7 and the inlet end of the sagger cover conveyor 10 are connected to the flatbed trolley transport unit via an overhead transfer and unloading device 15. The sagger conveyor 7 is sequentially equipped with a tilting and cleaning device 11 for tilting and cleaning the cooked crucibles and saggers, and a sagger bottom material filling device 9 along the conveying direction. A transition conveyor 12 is provided between the tilting and cleaning device 11 and the finished product transport unit. The raw crucible transport unit is connected to the outlet end of the sagger conveyor 7 via an overhead transfer and filling device 4. The outlet end of the sagger conveyor 7 and the outlet end of the sagger cover conveyor 10 are connected to the flatbed trolley transport unit via an overhead transfer and capping device 6. The flatbed trolley transport unit includes several flatbed trolleys 17.

[0020] Specifically, the raw crucible transport unit includes a raw crucible conveyor 2. The raw crucible conveyor 2 has a raw crucible tilting device 1 at its inlet end and a first clamping and positioning device 3 at its outlet end. The first clamping and positioning device 3 includes a clamping plate with two parallel arc-shaped grooves on one side and a cylinder connected to the other side. The sagger conveyor 7 also has a second clamping and positioning device 5 and a third clamping and positioning device 8. The second clamping and positioning device 5 is located at the outlet end of the sagger conveyor 7, and the third clamping and positioning device 8 is located inside the sagger bottom material filling device 9. The second clamping and positioning device 5 and the third clamping and positioning device 8 have the same structure as the first clamping and positioning device 3.

[0021] Specifically, the finished product transport unit includes a cooked crucible conveyor 13 and a finished product conveyor 16. The inlet end of the cooked crucible conveyor 13 is connected to the transition conveyor 12, and the outlet end of the cooked crucible conveyor 13 is connected to the finished product conveyor 16 through a cooked crucible tilting device 14. The inlet end of the cooked crucible conveyor 13 is provided with a manual cleaning auxiliary station 18.

[0022] Workflow:

[0023] In the raw crucible transport unit, the transported raw graphite crucibles are placed horizontally. The raw crucible tilting device 1 flips the raw graphite crucibles, turning them into vertical crucibles, which are then placed on the raw crucible conveyor 2. Upon reaching the outlet of the raw crucible conveyor 2, they are clamped and positioned by the first clamping and positioning device 3, and then wait.

[0024] In the processing unit, the calcined graphite crucible assembly is transported to a designated location via a flatbed trolley 17. An aerial transfer and capping device 15 transfers the calcined graphite crucible assembly from the flatbed trolley 17 to the sagger conveyor 7, and opens the sagger lid, transferring it to the sagger lid conveyor 10. The sagger conveyor then transports the capped calcined graphite crucible assembly to a tilting and cleaning device 11, which tilts the calcined graphite crucible assembly to separate the calcined filling material from the crucible inside the sagger. The inside of the sagger is then cleaned, and the calcined filling material is recovered for reuse. The separated calcined crucible is transferred to a transition conveyor 12. The cleaned sagger is then rotated in the opposite direction by the tilting and cleaning device 11 back to the sagger conveyor 7 and transported to the sagger bottom filling device 9. The third clamping and positioning device 8 clamps the crucible, then fills the inside of the crucible with firing base material and compacts it. After the crucible is filled with firing base material, it continues to be transported to the outlet end of the crucible conveyor, where the second clamping and positioning device 5 clamps it. The aerial transfer filling device 4 transfers the green graphite crucible on the green crucible conveyor 2 to the inside of the crucible already filled with firing base material on the crucible conveyor 7, fills it with firing filler and compacts it. After completing the above steps, the aerial transfer filling device 4 returns to the upper part of the green crucible conveyor 2. The aerial transfer capping device 6 places the crucible cap conveyed by the crucible cap conveyor 10 onto the green graphite crucible assembly that has been filled with firing filler and transfers the whole assembly to the flatbed trolley 17. The flatbed trolley 17 then sends it to the furnace for firing.

[0025] In the finished product conveying unit, the cooked crucible conveyor 13 receives the cooked crucibles transported by the transition conveyor 12. Workers inspect the cooked crucibles and clean the residual firing fillers at the manual cleaning auxiliary station 18 set at the inlet end of the cooked crucible conveyor 13. After passing the inspection, the cooked crucibles continue to be conveyed forward to the outlet end of the cooked crucible conveyor 13, where the cooked crucible tilting device 14 changes the horizontally placed cooked crucibles into vertically placed ones and places them on the finished product conveyor 16 for subsequent packaging and shipment.

[0026] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
