Description

Technical Field

[0001] The utility model relates to the field of graphitization processing, in particular to a box-type graphitization furnace cover plate disassembly and assembly auxiliary device. Background Art

[0002] Box-type graphitization furnaces are used in the production of graphite materials for negative electrodes of lithium batteries. In the prior art, box-type graphitization furnaces use multiple partitions to divide the entire furnace core into several chambers, and the raw materials are directly placed in a material box surrounded by graphite plates. Since the graphite plates are conductive, the material box itself generates heat after power is turned on. While serving as a container for the raw materials, the material box can also achieve the purpose of heating and keeping the materials warm. After the box-type graphitization furnace is loaded, it is necessary to lay insulation auxiliary materials on top of the materials. In order to prevent the insulation auxiliary materials from mixing with the raw materials, a cover plate used to isolate the insulation auxiliary materials from the raw materials needs to be set between the raw materials and the insulation auxiliary materials. The cover plate is also made of conductive graphite. However, both the early installation of the cover plate and the later removal of the cover plate are inconvenient to operate, and there are even safety risks. Take disassembly work as an example. Because impurities in graphitized materials volatilize at high temperatures, materials sink, causing the cover to collapse. Before the furnace is taken out, the cover needs to be removed manually. However, the furnace surface is wide, and it is very easy for people to fall due to unstable stepping during manual work. The existing solution mainly uses wooden pallets to cover the graphitized cover for operators to step on. However, the need to move the pallets frequently is not only inefficient, but also easy to mix with foreign matter, which needs to be solved urgently. Summary of the invention

[0003] In order to solve the technical problems in the background technology that there are safety hazards, labor-intensive, low efficiency, and graphitized materials are easily contaminated by foreign matter when removing the box-type graphitization furnace cover, the utility model proposes a box-type graphitization furnace cover disassembly and assembly auxiliary device.

[0006] Preferably, the support assembly specifically includes: a support member supported on the first furnace wall or the second furnace wall when the disassembly and assembly auxiliary device is used in conjunction with the furnace body, and a connecting portion connecting the support member and the workbench, wherein the connecting portion is arranged vertically.

[0007] Preferably, guide grooves extending along the length direction are provided on the top walls of the first furnace wall and the second furnace wall, and the support member specifically includes a guide wheel group and a mounting frame.

[0018] The design scheme is described in detail below with reference to the accompanying drawings.

A plurality of partitions 13 are installed between the first furnace wall 11 and the second furnace wall 12 relatively included in the graphitization furnace. The plurality of partitions 13 divide the furnace cavity into a plurality of compartments. The disassembly and assembly auxiliary device 2 specifically comprises: two groups of support components 21 and a workbench 22 connected between the two groups of support components 21.

When in use, the operator stands on the workbench 22, and the workbench 22 is close to the disassembly and assembly position of the cover plate 15, which is convenient for disassembly and assembly. The workbench 22 can also be used to temporarily place the cover plate 15 to avoid the cover plate 15 from bearing weight, thereby avoiding safety risks.

[0020] like Figure 2 , Figure 3 As shown, the support assembly 21 specifically includes: when the box-type graphitization furnace cover assembly and disassembly auxiliary device 2 is used in conjunction with the furnace body, the support assembly 21 is supported on the first furnace wall 11 or the second furnace wall 12, and a connecting portion 23 connecting the support assembly 21 and the workbench 22, and the connecting portion 23 is arranged vertically. The support assembly 21 is not only structurally stable, but also easy to process and has a relatively low cost.
