Description

Technical Field

[0001] The utility model relates to the technical field of sintering processing equipment for biomass hard carbon negative electrode materials, in particular to a sintering device for biomass hard carbon negative electrode materials. Background Art

[0002] Multi-stage sintering of biomass hard carbon negative electrode materials is an advanced sintering technology designed to optimize the microstructure of the material and thus improve its performance in the battery. This method can more finely control the physical and chemical properties of hard carbon materials by sintering in stages and at different temperatures. This multi-stage sintering is usually divided into the following stages:

[0003] Pre-sintering stage: In this stage, the biomass raw materials are first processed at a relatively low temperature. This step is intended to remove moisture and other volatile components in the biomass, while beginning to form a preliminary carbon structure. Pre-sintering is usually carried out at a temperature of several hundred degrees.

[0004] Medium temperature sintering stage: Next, the material is sintered at a medium temperature. During this stage, the microstructure of the material will further transform to form a more ordered carbon structure. This helps to improve the conductivity and structural stability of the material.

[0005] High temperature sintering stage: Finally, a high temperature sintering step may be performed. This step is usually over 2000°C, the purpose of which is to further improve the crystallinity of the material and reduce defects, thereby achieving optimal electrochemical performance.

[0006] Through this multi-stage sintering process, important parameters such as the porosity, specific surface area, electrochemical activity and structural order of hard carbon materials can be effectively controlled. This method helps to improve the capacity, cycle stability and rate performance of hard carbon materials, making them more suitable as negative electrode materials for high-performance lithium-ion batteries.

[0007] The patent application number is 202220759309.9, which discloses a sintering device for hard carbon negative electrode materials. It relates to the technical field of hard carbon negative electrode materials, including a sintering device and a switch door arranged in the middle of one side of the sintering device. A protective component is arranged in the middle of the lower end of the sintering device. When the operator takes the sintered hard carbon negative electrode material, he can pull the handle to slide the flat plate out of the inner cavity of the embedded groove before opening the switch door. The long strip is fixedly installed on both sides of the lower end of the sintering device. After pulling the flat plate out, open the switch door to take the hard carbon negative electrode material. If the hard carbon negative electrode material falls during the taking, it will fall directly to the upper end of the placement plate. During daily taking, if the sintered hard carbon negative electrode material is small, the operator can directly place it on the upper end of the placement plate, and start the heat dissipation fan as needed to temporarily dissipate the heat of the hard carbon negative electrode material arranged on the upper end of the placement plate through heat transfer, which is more flexible to use.

[0008] However, according to the applicant, the above-mentioned equipment is only applicable to the sintering process of single-stage biomass hard carbon negative electrode materials, and cannot be applied to the sintering process of multi-stage biomass hard carbon negative electrode materials.

The grabbing hand module 42 is provided with multiple groups, and the grabbing hand module 42 is reciprocatingly arranged to grab the material barrel 5 for step-by-step movement switching. The number of the grabbing hand module 42 is N, and the number of the sintering furnace single machine 10 is n, and N and n satisfy the relationship: N=n+1. Accordingly, when the sintering furnace single machine 10 is provided with three groups, the corresponding There are four groups of grabbing hand mold groups 42. The grabbing hand mold groups 42 of the first group reciprocate between the loading platform 2 and the sintering furnace single machine 10 of the first group, the grabbing hand mold groups 42 of the second group reciprocate between the sintering furnace single machine 10 of the first group and the sintering furnace single machine 10 of the second group, the grabbing hand mold groups 42 of the third group reciprocate between the sintering furnace single machine 10 of the second group and the sintering furnace single machine 10 of the third group, and the grabbing hand mold groups 42 of the fourth group reciprocate between the sintering furnace single machine 10 of the third group and the unloading platform 3.

Silicon carbide has excellent high temperature resistance, thermal conductivity and chemical stability, and is suitable for sintering furnace insulation layers with higher requirements.

[0072] Embodiment 2:

[0073] like Figures 4 to 8 As shown, with reference to Example 1, the difference between Example 2 of the utility model and Example 1 is described as follows:

[0079] The Z-axis moving unit 423 is installed on the Y-axis moving unit 422, and the Z-axis moving unit 423 drives the grabber 424 to move in a horizontal direction perpendicular to the length direction of the truss 41. The grabber 424 is installed on the moving end of the Z-axis moving unit 423, and the grabber 424 includes two groups of symmetrically arranged grabber forks 4241, which cooperate with the fixed block 53 to fork the material barrel 5.

[0080] Correspondingly, the X-axis moving unit 421 includes an X-axis slide rail pair 4211, an X-axis sliding seat 4212, an X-axis gear pair 4213 and an X-axis motor 4214;

[0081] The slide rails in the X-axis slide rail pair 4211 are arranged along the length direction of the truss 41 , and the sliders in the X-axis slide rail pair 4211 are installed on the X-axis slide seat 4212 ;

[0082] The rack of the X-axis gear pair 4213 is arranged along the length direction of the truss 41 , and the gear of the X-axis gear pair 4213 is installed on the X-axis motor 4214 ;

[0083] The X-axis motor 4214 is installed on the X-axis sliding seat 4212, and the X-axis motor 4214 drives the X-axis sliding seat 4212 to slide.
