Technical Field

[0001] This application relates to the technology of opening and closing the cover for unloading the filler of a graphitized crucible, and more particularly to a device for opening and closing the cover of a graphitized crucible for negative electrode materials. Background Technology

[0002] Graphitization of anode materials is completed by loading the anode material into a crucible and heating it at high temperature in a graphitization furnace. The crucible is covered after loading the anode material to reduce heat loss during graphitization and to protect the material from air.

[0003] During material discharge, the crucible is transported to the graphitization crucible lid-opening device via a crucible conveyor. The lid is opened using the clamping mechanism of the graphitization crucible lid-opening device, and then the crucible is moved to the material suction device for unloading. The crucible lids are manually stacked and transported in quantitative quantities. The stacked crucible lids are then quantitatively transferred to the crucible filling device. After the negative electrode material is refilled into the crucible, the crucible lid is placed back on the crucible for repeated graphitization of the negative electrode material.

[0004] The existing crucible lids, after being opened and sent out by the crucible lid conveyor, require a large number of workers to stack them in the transfer box, and then transfer them by forklift. The labor cost for stacking is high and the transfer efficiency is low. Utility Model Content

[0005] This application provides a device for removing and placing the lid of a graphitized crucible for negative electrode materials, which solves the problems of existing graphitized crucible lid removal and placement devices not having the function of receiving and storing crucible lids, and the inconvenience of transporting crucible lids.

[0006] This application provides a device for lifting and placing a crucible lid for graphitization of negative electrode materials, including a receiving box. The bottom of the receiving box is provided with lockable casters. One side of the receiving box is provided with an opening for docking with a crucible lid conveyor. A guide rail is vertically fixed on the inner wall of the receiving box. A support plate is slidably connected on the guide rail.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0019] like Figures 1-3 As shown, one embodiment of this application provides a device for lifting and lowering a graphitized crucible lid for a negative electrode material. The device includes a receiving box 6, with lockable casters at the bottom. One side of the receiving box 6 has an opening for docking with a crucible lid conveyor 3. A guide rail 8 is vertically fixed to the inner wall of the receiving box 6, and a support plate 7 is slidably connected to the guide rail 8. A through groove 9 is provided on the other side wall of the receiving box 6. The support plate 7 extends through the through groove 9 and is vertically connected to a threaded screw 10. The lower end of the screw 10 is fixed to the output shaft of a stepper motor 11, and the upper end of the screw 10 is rotatably connected to a fixing plate 12 fixed to the outer wall of the receiving box 6. The stepper motor 11 is controlled to rotate via electrical pulse signals. Each rotation of the screw 10 by the stepper motor 11 raises or lowers the support plate 7 by the thickness of a crucible lid 5.

[0020] When crucible 4 is discharged, it is transported to the graphitization crucible lid removal device via crucible conveyor 2. The clamping mechanism on the frame 1 clamps the crucible lid 5, opens it upwards, and places it on the crucible lid conveyor 3. The crucible lid 5 is then transported to the receiving box 6 via the crucible lid conveyor 3. After entering through the opening of the receiving box 6, the crucible lid 5 is placed on the pallet 7. The stepper motor 11 rotates the lead screw 10 to move the pallet 7 downwards, facilitating the stacking of subsequent crucible lids 5 on top. The crucible lids 5 are stacked in the receiving box 6 for easy movement to the filling area of ​​crucible 4. After the crucible lid 5 is removed, crucible 4 is transferred to the suction device via crucible conveyor 2 for unloading.

[0021] In this embodiment, a receiving box 6 capable of stacking crucible lids 5 is added to the graphitization crucible lid lifting and lowering device. The crucible lids 5, which are clamped and opened during discharge, are directly transported to the receiving box 6 via the crucible lid conveyor 3, reducing labor costs and improving the efficiency of the crucible lid lifting and lowering process. Furthermore, the crucible lids 5 stored in the receiving box 6 can be moved directly to the filling area as a whole for use, further improving the transfer efficiency of the crucible lids 5.

[0022] In one possible implementation, a guide roller 13 for delivering the crucible lid 5 into the box is provided below the opening of the receiving box 6. The guide roller 13 is rotated by a drive device mounted on the side.

[0023] The guide roller 13 rotates via a drive device, connecting the inside and outside of the receiving and discharging box 6, and transferring the crucible cover 5 that passes through at the top.

[0024] In one possible implementation, the receiving box 6 is provided with an arc-shaped push plate 14 for pushing the crucible lid 5 to the crucible lid conveyor 3. The push plate 14 is moved and pushed by a push rod 15 that passes through the side wall of the receiving box 6. The push rod 15 is driven by a geared motor 16 and a lead screw 17 mounted on the fixed plate 12.

[0025] The inner arc surface of the push plate 14 faces the opening of the receiving box 6, and two push rods 15 passing through the receiving box 6 are symmetrically fixed on the outer arc surface. The geared motor 16 is mounted on the upper end of the fixed plate 12, and the horizontally arranged lead screw 17 is threaded through the connecting plate between the two push rods 15. The rotation of the lead screw 17 by the geared motor 16 causes the push rods 15 to move along the length direction, and pushes the crucible cover 5 in the receiving box 6 from the opening onto the crucible cover conveyor 3 through the push plate 14.

[0026] The crucible lid 5 is pushed to the crucible filling device via the receiving box 6 and docked with the crucible lid conveyor 3 on the graphitized crucible lid lifting device downstream of the crucible filling device. The crucible lid 5 in the receiving box 6 is pushed onto the crucible lid conveyor 3 via the push plate 14, and the crucible filled with negative electrode material is closed by the graphitized crucible lid lifting device.

[0027] In one possible implementation, the opening of the receiving box 6 is located above the crucible lid 5 and is rotatably connected to a roller brush 18 that is driven by a drive device.

[0028] When the crucible lid 5 enters the receiving box 6, the top surface of the crucible lid 5 is cleaned by rotating the roller brush 18 through the drive device to prevent the particulate debris on the crucible lid 5 from sticking to the upper crucible lid 5 and preventing it from being placed flat.

[0029] In one possible implementation, a dust collection box 19 is provided above the roller brush 18, and the dust collection box 19 has a suction port facing the roller brush 18. A negative pressure fan 20 for suction is installed inside the dust collection box 19, and a filter plate 21 that can be detachably connected is installed between the negative pressure fan 20 and the suction port.

[0030] The particulate matter and debris cleaned by the roller brush 18 are sucked into the dust collection box 19 by the negative pressure fan 20, and temporarily stored by the filter plate 21. The dust collection box 19 is opened for periodic cleaning.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
