Description

Technical Field

[0001] The utility model relates to the technical field of graphitization furnaces, in particular to a graphitization furnace with automatic heating and cooling functions. Background Art

[0002] With the development of new energy power, lithium-ion batteries are increasingly favored by investors. As a key component of lithium-ion batteries, the market for carbon negative electrode materials is also facing explosive growth. A key step in the production process of carbon negative electrode materials is to increase the degree of graphitization and purity. Graphitization refers to the transformation of carbon atoms from a disordered and irregular arrangement to a regularly arranged hexagonal planar network structure, namely, a graphite microcrystalline structure, at high temperatures. The purpose is to obtain graphite's high electrical conductivity, high thermal conductivity, corrosion resistance, and friction resistance. The graphitization temperature can be as high as 3100°C. The higher the temperature, the more perfect the development of the graphite microcrystalline structure, thereby increasing the degree of graphitization. At the same time, at such a high temperature, other atoms with low melting points are discharged in the form of gas, thereby achieving material purification.

[0003] After use, the current graphitization furnace needs to wait until it cools down before it can be recycled. Usually, the cooling process of the graphitization furnace adopts natural cooling, which results in a long waiting time for cooling, thereby reducing the production efficiency of graphite. Therefore, a graphitization furnace with automatic heating and cooling is proposed. Utility Model Content

[0029] like Figures 1 to 6 As shown, a graphitization furnace with automatic heating and cooling comprises: a fixed barrel 1, the fixed barrel 1 is open at one end, a heating tank 101 is provided inside the fixed barrel 1, a heating layer 103 is provided between the heating tank 101 and the fixed barrel 1, a cavity 104 is provided inside the heating tank 101, a water inlet pipe 102 and a first water outlet pipe 109 are provided outside the cavity 104, and the water inlet pipe 102 and the first water outlet pipe 109 are both connected to the cavity 104; a fixed cover 2 is provided outside the heating tank 101 for sealing the heating tank 101; a first heat absorbing member 3 is provided inside the heating tank 101 for cooling the inside of the graphite, specifically, when processing the graphite After completion, the cavity 104 inside the fixed barrel 1 and the first heat absorption component 3 are used to cool the completed graphite from the inside and outside simultaneously, thereby increasing the cooling speed of the graphite after processing. Heat-absorbing liquid can flow inside the cavity 104 and the first heat absorption component 3. The fixed barrel 1 protects the heating tank 101 while blocking the temperature of the heating tank 101. The heating layer 103 is heated by electromagnetic induction. The heating layer 103 includes a support tube and a wire. The wire is arranged inside the support tube, and the support tube fixes the position of the wire. The wire can heat the material inside the heating tank 101 during use. The heating layer 103 is a prior art and will not be explained in detail here.

[0030] like Figures 1 to 6 As shown, a guide plate 105 is further provided inside the cavity 104, and a connecting hole 106 and a connecting groove 107 are further provided inside the heating tank 101, and the connecting hole 106 is connected to the water inlet pipe 102. A plurality of connecting pipes 108 are provided on the outside of the heating tank 101, and a second heat-absorbing component 4 for further cooling the graphite is further provided inside the heating tank 101. Specifically, when it is necessary to heat the processed graphite, the heat-absorbing liquid is first introduced into the cavity 104 and the first heat-absorbing component 3 through the water inlet pipe 102, so as to cool the processed graphite. The guide plate 105 can increase the time for the heat-conducting liquid to flow inside the cavity 104 during use, thereby ensuring the heat absorption effect of the heat-conducting liquid. The guide plate 105 can be a spiral plate or a continuously staggered plate. The first water outlet pipe 109 guides the heat-conducting liquid during use, so that the heated heat-conducting liquid is discharged, thereby improving the cooling effect of the graphite.

[0031] like Figures 1 to 6 As shown, the fixed cover 2 is arranged at the open end of the heating tank 101. Specifically, during use, the heating tank 101 is sealed by the fixed cover 2 to prevent graphite from overflowing from the inside of the heating tank 101 during use. The fixed cover 2 and the heating tank 101 can be connected by bolts or snaps to ensure the stability of the fixed cover 2 when connected to the heating tank 101.

[0032] like Figures 1 to 6 As shown, the first heat absorption component 3 includes a fixed column 301, which is connected to the heating tank 101 and is located directly above the connecting hole 106. A second water outlet pipe 302 is provided on the outside of the fixed column 301, and one end of the second water outlet pipe 302 passes through the fixed cover 2. A guide plate 303 is provided inside the fixed column 301. Specifically, during use, the heat-conducting liquid enters the fixed column 301 through the water inlet pipe 102 and the connecting hole 106. The heat-conducting liquid entering the fixed column 301 fully absorbs the heat of the graphite under the guidance of the guide plate 303. The guide plate 303 is spirally shaped, thereby extending the flow path of the heat-conducting liquid inside the fixed column 301, ensuring that the heat-conducting liquid can fully cool the graphite. The shape of the fixed column 301 can be cylindrical, hexagonal or elliptical.

[0033] like Figures 1 to 6 As shown, the second heat absorbing member 4 includes a first fixed tube 401 and a second fixed tube 402, the first fixed tube 401 and the second fixed tube 402 are arranged inside the heating tank 101, the sizes of the first fixed tube 401 and the second fixed tube 402 are gradually reduced, and the axis of the first fixed tube 401 and the second fixed tube 402 are parallel to the height direction of the heating tank 101, the first fixed tube 401 and the second fixed tube 402 are respectively provided with a groove 403 relative to the end of the heating tank 101, and the connecting groove 107 is connected to the first fixed tube 401 and the second fixed tube 402, and the connecting tube 108 is connected to the first fixed tube 401 and the second fixed tube 402. The fixed tubes 402 are connected. Specifically, when the graphite is cooled, the first fixed tube 401 and the second fixed tube 402 are connected through the cooperation of the connecting tube 108 and the connecting groove 107, so that the heat-conducting liquid can flow in the groove 403 inside the first fixed tube 401 and the second fixed tube 402 to absorb heat, thereby further increasing the cooling rate of the graphite. The contact area between the heat-conducting liquid and the graphite during cooling is increased by the cooperation of the first fixed tube 401 and the fixed column 301. The shape of the second fixed tube 402 can be a circular tube, a square tube or a hexagonal tube, etc.

[0034] like Figures 1 to 6 As shown, a barrier ring 404 is provided inside the first fixed tube 401 and the second fixed tube 402, one end of the barrier ring 404 is connected to the heating tank 101, and the height direction of the cavity 104 is parallel to the height direction of the first fixed tube 401. Specifically, when the heat-conducting liquid inside the first fixed tube 401 and the second fixed tube 402 absorbs heat and cools the graphite, the barrier ring 404 increases the flow time of the heat-conducting liquid inside the first fixed tube 401 and the second fixed tube 402, thereby improving the heat absorption efficiency of the heat-conducting liquid. The barrier ring 404 has the same shape as the first fixed tube 401 and the second fixed tube 402, and the barrier ring 404 can be a straight cylinder or a wavy barrel.
