[0001] This utility model belongs to the field of crucible filling technology, and in particular relates to a pre-carbonized crucible filling, compaction and venting device. Background Technology

[0002] In the carbonization process of lithium battery anode material preparation, artificial graphite powder or natural graphite powder needs to be placed in a crucible and calcined.

[0003] For example, patent CN217076295U discloses a graphitization crucible filling device, including a support, a buffer hopper, a motor, and a screw rod. The buffer hopper is fixed on the support and has an inlet and an outlet. The motor is located above the buffer hopper and connected to one end of the screw rod. The other end of the screw rod passes through the buffer hopper and is positioned at the outlet. A stirring blade is provided on the screw rod to stir the material in the hopper. The beneficial effects of this invention are: compared with the prior art, this invention has a simple structure, uses a screw to transport the material downwards, and has a stirring blade above the screw. The stirring blade stirs the material in the buffer hopper as the screw rod rotates, making the material entering the screw uniform. By combining the stirring blade with the screw, uniform material drop can be ensured, increasing the material density.

[0004] Existing pre-carbonized crucible filling, compaction, and venting devices require the removal of air from the graphite fines during use; however, the venting ports are prone to blockage during this process. Therefore, we propose a new pre-carbonized crucible filling, compaction, and venting device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a pre-carbonized crucible filling, compaction, and venting device to prevent the venting port from becoming easily blocked.

[0006] In view of this, the present invention provides a pre-carbonized crucible filling, compaction and venting device, including a filling frame, a hopper fixedly connected to the top of the filling frame, a connecting cylinder fixedly connected to the bottom of the hopper, a filling plate fixedly connected to the bottom of the connecting cylinder, a through hole opened at the bottom of the filling plate, an venting frame fixedly connected to the outer wall of the filling plate, a negative pressure interface fixedly connected to the top of the venting frame, a pneumatic push rod fixedly connected to the outer wall of the connecting cylinder, a lifting seat fixedly connected to the output end of the pneumatic push rod, and a clearing needle fixedly connected to the bottom of the lifting seat.

[0007] Based on the above structure, the graphite fines in the connecting cylinder are filled into the crucible through the filling plate. At the same time, the negative pressure device generates negative pressure, which discharges the air in the graphite fines through the through hole, realizing the vacuum filling operation of the graphite fines. Meanwhile, the graphite fines are compacted by the filling plate. After the filling is completed, the pneumatic push rod drives the lifting seat to slide vertically. The sliding of the lifting seat drives the clearing needle to move, pushing out the impurities blocking the through hole.

[0008] Preferably, six sets of through holes are provided, and the six sets of through holes are distributed in a circular pattern at equal angles about the center of the filling plate. In this embodiment, by providing six sets of through holes, it is beneficial to uniformly discharge air from the graphite fines.

[0009] Preferably, the lifting seat is circular in shape and parallel to the filling plate. In this embodiment, after filling is completed, the pneumatic push rod drives the lifting seat to slide vertically, thereby realizing the vertical sliding operation of the lifting seat.

[0010] Preferably, there are six sets of unblocking needles, and each set of unblocking needles corresponds to one of the six sets of through holes. In this embodiment, it is convenient for the lifting seat to slide and drive the unblocking needles to move, so as to push out the impurities blocking the through holes.

[0011] Preferably, a conveying frame is fixedly connected to the outer wall of the filling frame, a conveying roller is provided at the top of the conveying frame, a lifting frame is provided on the inner wall of the filling frame, a positioning push rod is fixedly connected to the inner wall of the lifting frame, a push plate is fixedly connected to the output end of the positioning push rod, a connecting rod is screwed to both ends of the push plate, a telescopic plate is screwed to the outer wall of the connecting rod, a telescopic frame is fixedly connected to the outer wall of the telescopic plate, a positioning plate is fixedly connected to the top of the telescopic frame, and a gasket is provided on the outer wall of the positioning plate. In this embodiment, the push plate slides through the connecting rod to drive the telescopic plate to slide along the inner wall of the lifting frame, the telescopic plate drives the positioning plate at the top of the telescopic frame to slide synchronously, and the sliding of the positioning plate causes the gasket to fit tightly against the outer wall of the crucible, thereby realizing the positioning operation of the crucible.

[0012] Preferably, the conveying frame and the lifting frame are located at the same height. In this embodiment, this facilitates the conveying rollers to transport the crucible to the lifting frame.

[0013] Preferably, the gasket is arc-shaped. In this embodiment, by setting an arc-shaped gasket, it is easy for the positioning plate to slide and drive the gasket to fit tightly against the outer wall of the crucible.

[0014] The beneficial effects of this utility model are:

[0015] 1. The pre-carbonized crucible filling, compaction, and venting device uses a shim to push the plate, which slides along the inner wall of the lifting frame via a connecting rod. The telescopic plate then slides synchronously with the positioning plate at the top of the telescopic frame. The sliding of the positioning plate causes the shim to fit tightly against the outer wall of the crucible, thus achieving the positioning operation of the crucible.

[0016] 2. This pre-carbonized crucible filling, compaction, and venting device, through the setting of a filling plate and a clearing needle, allows the graphite fines in the connecting cylinder to be filled into the crucible through the filling plate. At the same time, the negative pressure equipment works to generate negative pressure, which discharges the air in the graphite fines through the through hole, realizing the vacuum filling operation of the graphite fines. Meanwhile, the filling plate compacts the graphite fines. After filling is completed, the pneumatic push rod works to drive the lifting seat to slide vertically. The sliding of the lifting seat drives the clearing needle to move, pushing out the impurities blocking the through hole. Attached Figure Description

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] This application discloses a pre-carbonized crucible filling, compaction, and venting device, including a filling frame 1, a hopper 2 fixedly connected to the top of the filling frame 1, a connecting cylinder 3 fixedly connected to the bottom of the hopper 2, a filling plate 4 fixedly connected to the bottom of the connecting cylinder 3, a through hole 5 opened at the bottom of the filling plate 4, an venting frame 6 fixedly connected to the outer wall of the filling plate 4, a negative pressure interface 7 fixedly connected to the top of the venting frame 6, a pneumatic push rod 8 fixedly connected to the outer wall of the connecting cylinder 3, a lifting seat 9 fixedly connected to the output end of the pneumatic push rod 8, and a clearing needle 10 fixedly connected to the bottom of the lifting seat 9.

[0026] Based on the above structure, the graphite fines in the connecting cylinder 3 are filled into the crucible through the filling plate 4. At the same time, the negative pressure device generates negative pressure, which discharges the air in the graphite fines through the through hole 5, realizing the vacuum filling operation of the graphite fines. Meanwhile, the graphite fines are compacted by the filling plate 4. After the filling is completed, the pneumatic push rod 8 drives the lifting seat 9 to slide vertically. The sliding of the lifting seat 9 drives the clearing needle 10 to move, pushing out the impurities blocking the through hole 5.

[0027] In one embodiment, six sets of through holes 5 are provided, and the six sets of through holes 5 are distributed in a circular manner at equal angles about the center of the filling plate 4.

[0028] In this embodiment, by setting six sets of through holes 5, it is beneficial to uniformly discharge air from the graphite fines.

[0029] In one embodiment, the lifting seat 9 is circular in shape and is parallel to the loading plate 4.

[0030] In this embodiment, after the filling is completed, the pneumatic push rod 8 drives the lifting seat 9 to slide vertically, thereby realizing the vertical sliding operation of the lifting seat 9.

[0031] In one embodiment, six sets of unblocking needles 10 are provided, and the six sets of unblocking needles 10 correspond one-to-one with the six sets of through holes 5.

[0032] In this embodiment, the lifting seat 9 is slidably driven to move the unblocking needle 10, which pushes out the impurities blocking the through hole 5.

[0033] In one embodiment, a conveying frame 11 is fixedly connected to the outer wall of the filling frame 1. A conveying roller 12 is provided at the top of the conveying frame 11. A lifting frame 13 is provided on the inner wall of the filling frame 1. A positioning push rod 14 is fixedly connected to the inner wall of the lifting frame 13. A push plate 15 is fixedly connected to the output end of the positioning push rod 14. A connecting rod 16 is screwed to both ends of the push plate 15. A telescopic plate 17 is screwed to the outer wall of the connecting rod 16. A telescopic frame 18 is fixedly connected to the outer wall of the telescopic plate 17. A positioning plate 19 is fixedly connected to the top of the telescopic frame 18. A gasket 20 is provided on the outer wall of the positioning plate 19.

[0034] In this embodiment, the push plate 15 slides through the connecting rod 16 to drive the telescopic plate 17 to slide along the inner wall of the lifting frame 13. The telescopic plate 17 drives the positioning plate 19 at the top of the telescopic frame 18 to slide synchronously. The sliding of the positioning plate 19 causes the pad 20 to fit tightly against the outer wall of the crucible, thereby realizing the positioning operation of the crucible.

[0035] In one embodiment, the conveyor frame 11 and the lifting frame 13 are located at the same height.

[0036] In this embodiment, the conveying roller 12 is used to transport the crucible to the lifting frame 13.

[0037] In one embodiment, the gasket 20 has an arc-shaped profile.

[0038] In this embodiment, by setting an arc-shaped pad 20, the positioning plate 19 can slide to make the pad 20 fit tightly against the outer wall of the crucible.

[0039] In this embodiment, the pre-carbonized crucible filling, compaction, and venting device is used as follows: First, the operator places the crucible in the conveying roller 12 on the conveying frame 11. Then, the conveying roller 12 operates to transport the crucible to the lifting frame 13. Next, the positioning push rod 14 operates to drive the push plate 15 to slide. The sliding of the push plate 15 drives the telescopic plate 17 to slide along the inner wall of the lifting frame 13 via the connecting rod 16. The telescopic plate 17 drives the positioning plate 19 at the top of the telescopic frame 18 to slide synchronously. The sliding of the positioning plate 19 causes the gasket 20 to fit tightly against the outer wall of the crucible, thereby achieving the positioning operation of the crucible.

[0040] Next, the lifting frame 13 lifts the crucible to below the filling plate 4. Then, the graphite fines in the hopper 2 are injected into the connecting cylinder 3. The graphite fines in the connecting cylinder 3 are filled into the crucible through the filling plate 4. At the same time, the negative pressure device generates negative pressure, which discharges the air in the graphite fines through the through hole 5, realizing the vacuum filling operation of the graphite fines. Meanwhile, the graphite fines are compacted by the filling plate 4. After the filling is completed, the pneumatic push rod 8 drives the lifting seat 9 to slide vertically. The sliding of the lifting seat 9 drives the clearing needle 10 to move, pushing out the impurities blocking the through hole 5.
