Description

Technical Field

[0001] This utility model relates to the field of graphitization furnace technology, and in particular to a water-cooled mobile graphitization furnace. Background Technology

[0002] Graphitization refers to a major production process in the production of carbon-graphite materials, in which amorphous carbon materials are transformed into graphitic materials at high temperatures (above 2500℃). Carbon-graphite materials are widely used in various industries such as metallurgy, machinery, chemicals, electronics, aerospace, transportation, lithium battery energy storage, and medicine. They are energy storage materials with excellent electrical conductivity, high-temperature resistance, friction resistance, and self-lubricating properties, and are indispensable and irreplaceable materials in modern industry, civilian use, and national defense. The high-temperature graphitization production of carbon-graphite materials is an essential production step.

[0003] After heating the material in the crucible, existing graphitization furnaces typically use natural air cooling to cool the material, which is inefficient and leads to reduced production efficiency. Utility Model Content

[0004] In view of this, it is necessary to provide a water-cooled mobile graphitization furnace to solve the technical problem that existing graphitization furnaces typically use natural air cooling to cool the material in the crucible after heating, which results in low cooling efficiency and reduced production efficiency.

[0005] To achieve the above objectives, this utility model provides a water-cooled portable graphitization furnace, including an outer shell layer, an insulation layer, and heating electrodes;

[0006] The outer shell has a sealed first receiving cavity, a cooling groove is formed in the wall of the outer shell, an inlet communicating with the cooling groove is opened at one end of the outer wall of the outer shell, and an outlet communicating with the cooling groove is opened at the other end of the outer wall of the outer shell.

[0007] The insulation layer is built into the first receiving cavity, and the insulation layer has a sealed second receiving cavity, which is used to place at least one crucible.

[0008] The heating electrode is housed within the second receiving cavity.

[0009] In some embodiments, a brick wall layer is embedded between the outer shell layer and the insulation layer.

[0010] In some embodiments, a first inlet / outlet is provided on the upper surface of the outer shell layer, and a second inlet / outlet is provided on the upper surface of the brick wall layer. A cover plate is detachably provided inside the first inlet / outlet and the second inlet / outlet.

[0011] In some embodiments, a first baffle and a second baffle are fixed in the cooling tank in an alternating manner. Each first baffle has a first notch between itself and the inner wall of the cooling tank, and each second baffle has a second notch between itself and the inner wall of the cooling tank. The first notch and the second notch are arranged opposite to each other.

[0013] In some embodiments, the water-cooled portable graphitization furnace further includes a main water inlet pipe, which is connected to each of the water inlets.

[0014] In some embodiments, the main water inlet pipe is connected to each of the water inlets via a plurality of first connecting pipes.

[0015] In some embodiments, the water-cooled portable graphitization furnace further includes a main water outlet pipe, which is connected to each of the water outlets.

[0016] In some embodiments, the main water outlet is connected to each of the water outlets via a plurality of second connecting pipes.

[0017] In some embodiments, the outer shell is a stainless steel outer shell.

[0018] Compared with existing technologies, the beneficial effects of the technical solution proposed in this utility model are as follows: In use, the material to be graphitized is loaded into each crucible. Then, the heating electrodes are energized, generating resistance heat to heat the material inside the crucible, thus graphitizing it. After heating, cold water is introduced through the inlet into a cooling tank and then discharged through the outlet. During this process, the cold water absorbs heat, thereby cooling the material inside the crucible. Once completely cooled, the graphitized material can be removed. This utility model, by setting a cooling tank within the wall of the outer shell and introducing cold water into the cooling tank, can greatly accelerate the cooling efficiency of the material inside the crucible, thereby improving production efficiency.

Detailed Implementation

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0023] Please refer to Figure 1 and Figure 2 This utility model provides a water-cooled portable graphitization furnace, including an outer shell layer 1, an insulation layer 2, and heating electrodes 3;

[0024] The outer shell layer 1 has a sealed first receiving cavity, and a cooling groove 11 is formed in the wall of the outer shell layer 1. One end of the outer wall of the outer shell layer 1 is provided with a water inlet 12 communicating with the cooling groove 11, and the other end of the outer wall of the outer shell layer 1 is provided with a water outlet 13 communicating with the cooling groove 11.

[0025] The insulation layer 2 is built into the first receiving cavity, and the insulation layer 2 has a sealed second receiving cavity, which is used to place at least one crucible 4.

[0026] The heating electrode 3 is housed within the second receiving cavity.

[0027] In use, the material to be graphitized is placed into each crucible 4, and then the heating electrode 3 is energized. The heating electrode 3 generates resistance heat, thereby heating the material in the crucible 4 and graphitizing it. After heating, cold water is introduced into the water inlet 12. The cold water enters the cooling tank 11 through the water inlet 12 and is discharged from the water outlet 13. During this process, the cold water absorbs heat, thereby cooling the material in the crucible 4. After complete cooling, the graphitized material can be removed. This invention, by setting a cooling tank 11 in the wall of the outer shell layer 1 and introducing cold water into the cooling tank 11, can greatly accelerate the cooling efficiency of the material in the crucible 4, thereby improving production efficiency.

Each first baffle 14 forms a first notch with the inner wall of the cooling tank 11, and each second baffle 15 forms a second notch with the inner wall of the cooling tank 11. The first notches and second notches are arranged opposite to each other. By setting the staggered first baffles 14 and second baffles 15, the path of the cold water during flow will be bent, thereby increasing the flow path of the cold water and improving the cooling effect.

In this embodiment, the partition plates 16 divide the cooling tank 11 into several non-communicating cooling units, which can prevent different areas from having different cooling rates due to different water inflow times, and can make the cooling rates of each area approximately equal.

[0037] To better understand this utility model, the following is combined with... Figure 1 and Figure 2 The working process of the water-cooled portable graphitization furnace provided by this utility model is described in detail below: In use, the material to be graphitized is loaded into each crucible 4. Then, the heating electrode 3 is energized, generating resistance heat to heat the material in the crucible 4, thereby graphitizing it. After heating, cold water is introduced into the water inlet 12. The cold water enters the cooling tank 11 through the water inlet 12 and is discharged from the water outlet 13. During this process, the cold water absorbs heat, thereby cooling the material in the crucible 4. Once completely cooled, the graphitized material can be removed. This utility model, by setting a cooling tank 11 within the wall of the outer shell layer 1 and introducing cold water into the cooling tank 11, can greatly accelerate the cooling efficiency of the material in the crucible 4, thereby improving production efficiency.
