Description

Technical Field

[0001] This utility model relates to the technical field of graphitization process of negative electrode materials, and in particular to a cooling device for a graphitization furnace of negative electrode materials. Background Technology

[0002] The graphitization process of anode materials is mainly used to transform carbon materials into highly ordered graphite structures in order to improve their conductivity, structural stability and lithium storage performance.

[0003] After the negative electrode material is graphitized in a graphitization furnace, the furnace still has a high temperature after heating is stopped. Currently, natural cooling is usually used, which is slow and makes the graphitization process of the negative electrode material very long and the production efficiency low. Utility Model Content

[0004] To address the aforementioned shortcomings, this invention provides a cooling device for a graphitization furnace of negative electrode materials, which can accelerate the cooling speed of the graphitization furnace, speed up material turnover time, and improve production efficiency.

[0005] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0006] A cooling device for a graphitization furnace of a negative electrode material, comprising:

[0007] The top plate has a first end plate extending downward from one end and a second end plate extending downward from the other end.

[0008] A toothed plate is disposed between the bottom ends of a first end plate and a second end plate. The toothed plate includes a base plate and a plurality of upwardly shaped teeth.

[0009] A pair of side plates extend downwards to the two ends of the top plate, with the two ends of the side plates connected to the first end plate and the second end plate respectively. The bottom edge of the side plates is connected to the side end of the toothed plate, and a cavity is formed between the top plate, the toothed plate, and the two side plates.

[0010] The water inlet is located at the first end plate;

[0011] The water outlet is located on the second end plate.

[0012] Furthermore, the tooth includes a pair of inclined surfaces and a horizontal surface disposed between the tops of the two inclined surfaces.

[0013] Furthermore, the number of teeth is twelve.

[0014] Furthermore, the height of the outlet is higher than the height of the inlet.

[0015] Furthermore, the bottom edge of the side panel is serrated.

[0016] The beneficial effects of this technical solution are as follows:

[0017] The multiple teeth on the toothed plate form parallel flow channels, achieving a low pressure drop and highly uniform cooling effect, suitable for uniform heat dissipation under high heat loads in graphitization furnaces. Furthermore, the geometric structure formed by the teeth enhances the rigidity of the toothed plate, preventing softening or deformation at high temperatures and improving reliability. The cooling device of this application can accelerate the cooling rate and improve production efficiency. Attached Figure Description

[0018] Figure 1 A front view of an embodiment of this application is shown. Detailed Implementation

[0019] The present application will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present application can be combined with each other.

[0020] like Figure 1 The cooling device for a graphitization furnace of negative electrode material shown includes a top plate 1, a toothed plate 4, a side plate 5, a water inlet 6, and a water outlet 7.

[0021] One end of the top plate 1 extends downward to a first end plate 2, and the other end extends downward to a second end plate 3.

[0022] The toothed plate 4 is disposed between the bottom ends of the first end plate 2 and the second end plate 3. The toothed plate 4 includes a base plate and a plurality of upwardly bent teeth. Each tooth includes a pair of inclined surfaces and a horizontal surface disposed between the top ends of the two inclined surfaces. In this embodiment, the number of teeth is twelve.

[0023] There is a pair of side plates 5, which extend downward to both sides of the top plate 1. The two ends of the side plates 5 are connected to the first end plate 2 and the second end plate 3 respectively. The bottom edge of the side plates 5 is toothed and connected to the side end of the toothed plate 4. A cavity is formed between the top plate 1, the toothed plate, and the two side plates.

[0024] Specifically, the top plate 1, toothed plate 4, and side plate 5 are made of stainless steel with a thickness of 5mm.

[0025] The inlet 6 is located on the first end plate 2. The inlet 6 can be opened and closed; specifically, a valve can be connected to the outside of the inlet 6 for control.

[0026] The outlet 7 is located on the second end plate 3, and its height is higher than that of the inlet 6. When the cooling water flows, dissolved gases or residual air in the water will gradually rise due to the density difference. If the outlet 7 is located at a higher position, air bubbles can be naturally discharged with the water flow instead of remaining at the top of the cavity, avoiding air resistance and ensuring continuous water flow. The outlet 7 can be opened and closed; specifically, a valve can be connected to the outside of the outlet 7 for control.

[0027] Work style:

[0028] Twenty-four hours after the graphitization furnace is powered on, the cooling device for the graphitization furnace of the negative electrode material is hoisted onto the furnace surface.

[0029] Connect stainless steel pipes to both the inlet 6 and the outlet 7. Then open the outlet 7 first, then open the inlet 6, and then flow water into the cooling device.

[0030] When the furnace surface temperature is below 100℃, first close the water inlet 6, then close the water outlet 7, and lift the cooling device off the furnace surface.

[0031] Use an auxiliary material crane to remove 400mm thick insulation material, then hoist the cooling device back onto the furnace surface, and repeat the above cooling steps until the furnace temperature drops to 40℃ to end the cooling process.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
