Description

Technical Field

[0001] This utility model relates to the field of negative electrode material calcination technology, and more specifically, to a sagger for calcining negative electrode materials. Background Technology

[0002] Anode materials are a key component of lithium-ion batteries, mainly including carbon materials (such as natural graphite and artificial graphite), silicon materials, and lithium metal. Among them, carbon materials are widely used due to their good conductivity and cycle stability. Anode materials need to possess properties such as high specific capacity, good cycle stability, and low volume expansion rate. In recent years, silicon-based anode materials have become a development trend due to their high specific capacity, while lithium metal anode materials are a potential future research direction. The preparation process of anode materials requires calcination in a crucible.

[0003] For example, Chinese patents disclose a sagger (application numbers: CN202311564114.4, CN202320605823.1), which includes a sagger body. The sagger body comprises a square base and walls surrounding the base. Chamfers are provided at the four corners of the base and walls to form longitudinal vents. Support plates are provided at the top of each wall. Walls without support plates form transverse vents with the top of the longitudinal vents. In use, multiple sagger bodies are stacked, with four different sagger bodies within the same square area forming a channel through the longitudinal vents. The transverse and longitudinal vents in the sagger body create both transverse and longitudinal ventilation channels between each layer during stacking, significantly improving the convection space for the reaction atmosphere and heat, and enhancing the convection effect of the reaction atmosphere. Simultaneously, the right angle between the base and walls ensures ventilation while maximizing the sintering area, greatly improving sintering efficiency.

[0004] However, in the above technical solution, when stacking different saggars, they are fixed only by the friction between the different saggars. Therefore, when the stacked saggars are transported, the saggars are very likely to fall off, causing unnecessary losses. At the same time, the saggars are relatively flat, which makes it inconvenient to move them. Utility Model Content

[0011] As preferred, the guide slide column, semicircular limit block and sagger main body are slidably connected.

[0012] As preferred, the side of the spring is fixedly connected with sagger main body.

[0013] Compared with the prior art, the utility model has the advantages of:

[0014] (1) when the sagger main body needs to be carried, the support plate is rotated by ninety degrees with the rotating column main body as the center, so that the support plate is perpendicular to the outer wall of the sagger main body, then the sagger main body can be carried by grabbing the support plate, which facilitates the staff to carry the sagger main body, when two sagger main bodies need to be spliced, the insertion plate of one sagger main body is inserted into the insertion slot, the limit plate is fixed by extrusion through the insertion plate, the support plate is fixed through the limit plate, the insertion plate is limited through the limit plate, so that the two sagger main bodies are stably spliced together, preventing the sagger main body from falling off when the staff transports the stacked sagger main body.

[0026] The working principle of the kind of negative electrode material roasting kiln is as follows:

[0027] When the kiln body 1 needs to be carried, first, the supporting plate 5 is rotated ninety degrees around the rotating column body 401, so that the supporting plate 5 is perpendicular to the outer wall of the kiln body 1, then the kiln body 1 can be carried by grabbing the supporting plate 5, which facilitates the carrying of the kiln body 1 by the staff, when two kiln bodies 1 need to be spliced, first, the plug plate 7 of one kiln body 1 is inserted into the insertion slot 2, the limiting plate 6 is extruded and fixed by the plug plate 7, the supporting plate 5 is fixed by the limiting plate 6, the plug plate 7 is limited by the limiting plate 6, so that the two kiln bodies 1 are stably spliced together, preventing the kiln body 1 from falling off when the staff transports the stacked kiln bodies 1.
