Description

Technical Field

[0001] This utility model relates to the field of lithium battery anode material production technology, specifically a novel current-guiding column overlapping structure. Background Technology

[0002] The production of lithium batteries is inseparable from artificial graphite. Graphitization is a key process in the production of artificial graphite, which mainly utilizes thermal activation to transform thermodynamically unstable carbon atoms from a disordered layer structure to an ordered graphite crystal structure. Currently, the industry uses the Atchison box furnace process for graphitization. The box is constructed by building a box with refractory bricks, graphite electrode strips, and graphite blocks. Semi-graphite materials are used to make box panels of different specifications (including bottom plate, side plate, top cover plate, and baffle). Graphite powder is laid under the bottom plate, and carbon black powder is filled between the side plates and the outer furnace body. Finally, a box measuring 26.8m long x 4.2m wide x 2500mm is formed, which is filled with lithium battery negative electrode material (powder).

[0003] The existing drainage column is a standard cuboid. (See attached image) Figure 5 As shown, during furnace loading, the guide columns are longitudinally overlapped and laid flat on the negative electrode material. When these square guide columns are placed inside the furnace and overlapped vertically, the contact is unstable. The heat generated during high current transmission can easily cause the guide columns to bend and deform, forming gaps at the contact points. This can cause the guide columns to arc, causing the current to deviate from the furnace core, increasing power consumption and affecting product quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a new type of diversion column overlapping structure, which can optimize the power supply method, reduce energy consumption, increase the unit power supply efficiency, and steadily improve product quality, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel drainage column overlapping structure, comprising a box and the material filled inside it, wherein a drainage network is laid in layers inside the material, the drainage network comprising longitudinal drainage lines, the longitudinal drainage lines being formed by overlapping three or more drainage columns, the two ends of the longitudinal drainage lines being electrically connected to the end plates of the conductive box, and drainage columns being overlapped between adjacent longitudinal drainage lines to form a drainage network.

[0006] As a preferred technical solution of this utility model, the drainage columns in the drainage network are of three types: type A drainage column, type B drainage column, and type C drainage column. The cross-section of type A, type B, and type C drainage columns is rectangular. Among them, type A drainage column is a cuboid that overlaps two adjacent longitudinal drainage lines. One end face of type B drainage column is a sloping surface, and the other end face is a vertical surface. One end of the vertical surface of type B drainage column overlaps with the end plate of the box. Both ends of type C drainage column are sloping surfaces. When type B drainage column and type C drainage column overlap to form a longitudinal drainage line, the bevels are tightly abutted.

[0007] As a preferred embodiment of this utility model, the main view of the C-type drainage column is a parallelogram, and the inclination angle of the sloping end face of the B-type drainage column is the same as that of the C-type drainage column.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. The mesh-like overlapping between the flow columns enhances the stability of the flow columns during furnace loading, effectively avoids loose connections, reduces the probability of electric arcs, and improves production safety.

[0010] 2. It achieves balanced power delivery, higher conductivity, reduced energy consumption, and improved product quality and unit power delivery efficiency;

[0011] 3. The overlapping method of the mesh-type diversion column effectively avoids the loose connection caused by the bending and deformation of the diversion column when the material reaches a temperature of 2200℃ during the power supply process. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4This utility model provides a technical solution: a novel diversion column overlapping structure, including a box 1 and the material 2 filled inside it. A diversion network 3 is laid in layers inside the material 2. The diversion network 3 includes longitudinal diversion lines, which are formed by overlapping three or more diversion columns 4. The two ends of the longitudinal diversion lines are electrically connected to the end plates of the conductive box 1. A transverse diversion column 4 is overlapped between two adjacent longitudinal diversion lines to form a diversion network, which plays the role of mutual communication and flow, changing the longitudinal DC power transmission into longitudinal planar power transmission and improving the power transmission efficiency.

[0020] The drainage columns 4 in the drainage network 3 are of three types: type A drainage column 41, type B drainage column 42, and type C drainage column 43. The cross-sections of all three types are rectangular. Type A drainage column 41 is a cuboid, overlapping two adjacent longitudinal drainage lines. Type B drainage column 42 has a sloping end and a vertical end, with the vertical end overlapping the end plate of the box 1. Type C drainage column 43 has sloping ends. Type B drainage column 42 overlaps with the end plate of the box 1. When the C-type diversion columns 43 overlap to form a longitudinal diversion line, the bevels are tightly joined. The main view of the C-type diversion column 43 is a parallelogram. The inclination angle of the sloping end face of the B-type diversion column 42 is consistent with that of the C-type diversion column 43. This makes the connection of the overlapping C-type diversion columns 43 more stable under the gravity pressure of the A-type diversion column 41, effectively avoiding incomplete connections, reducing the probability of generating electric arcs, and improving production safety. During the power supply process, when the material reaches a temperature of 2200℃, it can also effectively avoid incomplete connections caused by the bending deformation of the C-type diversion column 43.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
