[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

[0027] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the first embodiment of a heat preservation device for the production of lithium battery negative electrode materials provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the insulation box. An insulation device for the production of lithium battery negative electrode materials includes: a main body 1, the main body 1 including an insulation box 11, an insulation mechanism 2 disposed on the surface of the insulation box 11, and the insulation mechanism 2 including an insulation cavity 21 connected to the interior of the insulation box 11;

[0028] The isolation mechanism 3 includes a drawer 31, which is connected to the interior of the insulation cavity 21.

[0029] Heating mechanism 4, which includes a gas pipe 42, is fixedly installed inside the insulation box 11.

[0030] The insulation box 11 consists of an outer shell, an insulation layer, and an inner lining. The outer shell is made of stainless steel, which has high mechanical strength and high temperature resistance, making it suitable for long-term repeated use. The insulation layer is made of glass wool, which has high temperature resistance. The inner lining is made of polytetrafluoroethylene, which has strong corrosion resistance, is non-stick, and is resistant to high and low temperatures. The function of the insulation mechanism 2 is to support and seal the isolation mechanism 3 to achieve insulation of the negative electrode sheet. There are multiple insulation cavities 21, which are fixedly connected to the inner surfaces of the left and right ends of the insulation box 11. Their composition and materials are the same as those of the insulation box 11, and they have a high insulation effect. The function of the isolation mechanism 3 is to store the negative electrode sheet separately to prevent external air from entering and affecting the temperature of the negative electrode sheet. There are multiple isolation mechanisms 3, and each drawer 31 is embedded in the interior of each insulation cavity 21, and its size is just right to be embedded in the interior of the insulation cavity 21. The function of the heating mechanism 4 is to heat the insulation water inside the insulation box 11 and then transfer it to the surface of the insulation cavity 21 to achieve insulation of the negative electrode sheet.

[0031] The top of the heat preservation box 11 is connected to a water inlet 12, and the two ends of the heat preservation cavity 21 are respectively provided with a discharge port 22 and a feed port 23. A support plate 24 is connected to the outer surface of the heat preservation box 11 at one end of the heat preservation cavity 21.

[0032] A valve is installed on the surface of the water inlet 12, which allows the addition of insulation water to the inside of the insulation box 11. A drain valve is connected to one end of the insulation box 11 near the bottom, which allows the insulation water inside the insulation box 11 to be discharged. The discharge port 22 and the inlet port 23 are respectively opened at the left and right ends of the insulation cavity 21 and the connection with the inner surface of the insulation box 11. The drawer 31 can be embedded into the inside of the insulation cavity 21 through the discharge port 22 and the inlet port 23. The support plate 24 is connected to the outer surface of the insulation box 11 at the opening end of the inlet port 23.

[0033] The drawer 31 has a sealed cavity 32 inside, and a material outlet 33 is provided at the bottom of the sealed cavity 32. The two ends of the drawer 31 are connected to handles 34.

[0034] The drawer 31 has multiple sealed cavities 32 arranged inside. Each negative electrode is placed inside each sealed cavity 32. Each sealed cavity 32 has a discharge port 33 at its bottom. When it is necessary to place the negative electrode inside the sealed cavity 32, the handle 34 at the feed port 23 end of the drawer 31 is pulled to connect the discharge port 33 to the support plate 24. Then the negative electrode is placed inside the sealed cavity 32 on the support plate 24. Then the drawer 31 is pushed into the heat preservation cavity 21, thereby moving the negative electrode into the heat preservation cavity 21 for heat preservation.

[0035] A heating box 41 is installed on the outer surface of one end of the heat preservation box 11, and an air filter 43 is installed on the top of the heat preservation box 11. An exhaust pipe 44 is connected to the top of the air filter 43.

[0036] The heating box 41 is fixedly installed on the outer surface of the insulation box 11 at the bottom of the bottom support plate 24. It heats the air with fuel. The heated air enters the gas pipe 42, which absorbs the heat from the air and heats up. It then transfers the heat to the insulation water inside the insulation box 11. The insulation water then transfers the heat to the surface of the insulation cavity 21, thus achieving the effect of heat preservation of the negative electrode plate inside the insulation cavity 21. Finally, the air is filtered by the air filter 43 and discharged from the exhaust pipe 44.

[0037] One end of the insulation box 11 is provided with a receiving mechanism 5, which includes a guide trough 51. The guide trough 51 is connected to the outer surface of one end of the insulation box 11, and the bottom of the guide trough 51 is connected to a receiving box 52.

[0038] The material guide trough 51 is fixedly connected to the outer surface of the insulation box 11 at the opening end of the discharge port 22, and its width is exactly the width of the discharge port 33. When the sealing cavity 32 is inside the material guide trough 51, the discharge port 33 is connected to the inside of the material guide trough 51, and the negative electrode sheet inside the sealing cavity 32 falls into the inside of the receiving box 52 through the discharge port 33 and along the inside of the material guide trough 51.

[0039] The working principle of the heat preservation device for lithium battery negative electrode material production provided by this utility model is as follows:

[0040] When it is necessary to keep the negative electrode sheet warm, first hold the handle 34 at one end of the drawer 31 located at the feed inlet 23 and pull it. The drawer 31 will slide out of the heat preservation box 11 from the feed inlet 23. Then, place the negative electrode sheet into the sealed cavity 32 in sequence, and then push it into the heat preservation cavity 21 for heat preservation. When it is necessary to remove the negative electrode sheet, hold the handle 34 at the end of the drawer 31 located at the discharge port 22 and pull it. When the sealed cavity 32 is pulled out of the heat preservation cavity 21 and moved into the guide trough 51, the negative electrode sheet inside the sealed cavity 32 will fall into the receiving box 52 through the sealed cavity 32. During this process, in order to centrally process the sealed cavity 32 that has moved into the guide trough 51, it is always in a sealed state connected to the surface of the heat preservation cavity 21 to prevent external air from entering the sealed cavity 32 and changing the temperature of the negative electrode sheet.

[0041] Compared with related technologies, the heat preservation device for the production of lithium battery negative electrode materials provided by this utility model has the following beneficial effects:

[0042] This utility model provides a heat preservation device for the production of lithium battery negative electrode materials. By placing the negative electrode sheets separately inside the drawer 31 and embedding them inside the heat preservation cavity 21, the heating mechanism 4 can heat the water inside the heat preservation box 11 and maintain a constant temperature, thereby achieving the effect of heat preservation for the negative electrode sheets. Furthermore, by pulling the drawer 31, the electrode sheets can be added sequentially and kept sealed to prevent air from entering the interior and causing temperature changes in the electrode sheets, thus improving the heat preservation effect of the heat preservation box 11.

[0043] Second Embodiment

[0045] Specifically, the difference in the second embodiment of this application regarding the heat preservation device for the production of lithium battery anode materials is that the heat preservation device for the production of lithium battery anode materials has a stirring mechanism 6 provided on the surface of the heat preservation box 11. The stirring mechanism 6 includes a stirrer 61, one end of which is connected to a transmission belt assembly 62, and a drive motor 63 is connected to the surface of the transmission belt assembly 62.

[0046] There are two stirrers 61, which are rotatably installed at the upper and lower ends inside the insulation box 11, respectively. The two ends of the two stirrers 61 are rotatably connected to the inner surfaces of the front and rear ends of the insulation box 11. The transmission belt assembly 62 consists of a gear belt with the surfaces of two gears meshing. The two gears are fixedly connected to the rear ends of the two stirrers 61. The drive motor 63 is fixedly connected to the surface of the top gear. The drive motor 63 drives the top gear to rotate, and the gear belt meshes with the gear. Then it meshes with the bottom gear, causing the bottom gear to drive the bottom stirrer 61 to rotate, thereby achieving synchronous rotation of the two stirrers 61.

[0047] The working principle of the heat preservation device for lithium battery negative electrode material production provided by this utility model is as follows:

[0048] During operation, the drive motor 63 drives the transmission belt assembly 62 to rotate, causing the two agitators 61 to rotate synchronously inside the insulation box 11, thereby keeping the insulation water inside the insulation box 11 in motion. The insulation water in different positions comes into contact with each other, transfers heat, and maintains temperature uniformity.

[0049] Compared with related technologies, the heat preservation device for the production of lithium battery negative electrode materials provided by this utility model has the following beneficial effects:

[0050] This utility model provides a heat preservation device for the production of lithium battery negative electrode materials. Driven by a drive motor 63 and driven by a transmission belt assembly 62, the stirrer 61 rotates inside the heat preservation box 11 to stir the heat preservation water, ensuring the uniformity of the heat preservation water temperature.
