At the same time, if the negative electrode material inside the crucible is bagged at this time, when the relatively hot negative electrode material is injected into the packaging bag, it will damage the packaging bag. Therefore, it is also necessary to perform a cooling treatment on the negative electrode material inside the crucible.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The present application will be further elaborated in detail below with reference to the drawings and embodiments.

[0030] Refer to Figure 1 and Figure 2 An embodiment of the present application provides a cooling device for the negative electrode material when it comes out of the furnace, including a pulverizing tank 1. A filling funnel 16 is installed at the top of the pulverizing tank 1, and the bottom of the filling funnel 16 extends into the interior of the pulverizing tank 1. The filling funnel 16 can be used to better fill the negative electrode material that needs to be cooled into the interior of the pulverizing tank 1. A discharge pipe 17 is installed on the outer side of the bottom of the pulverizing tank 1, and one end of the discharge pipe 17 extends into the interior of the pulverizing tank 1.

[0031] Inside the crushing tank 1, a crushing mechanism is provided for crushing the negative electrode material. At the top of the crushing tank 1, a driving mechanism is provided for driving the crushing mechanism to rotate. A cooling tank 2 is installed outside the crushing tank 1. Inside the cooling tank 2, a cooling mechanism is provided. A circulation mechanism is provided between the crushing tank 1 and the cooling tank 2. The cooling mechanism cooperates with the circulation mechanism to cool down the negative electrode material inside the crushing tank 1. By providing a crushing mechanism inside the crushing tank 1 and cooperating with the cooling mechanism and the circulation mechanism, it is possible to cool down the negative electrode material placed inside the crushing tank 1 while crushing it, cooling it from both the inside and the outside of the tank body, greatly improving the cooling effect, thereby avoiding the phenomenon of agglomeration of the negative electrode material and being beneficial to practical applications. At the same time, by setting up a circulation mechanism to cooperate with the cooling mechanism, it is possible to circulate and cool the air inside the equipment, thereby preventing external hot air from entering the equipment, and thus greatly reducing the energy consumption of the equipment.

[0032] Referring to Figure 1 , Figure 3 and Figure 4 , in one aspect of this embodiment, the cooling mechanism includes a thermoelectric cooler 3, an air guide groove 4, and a blower fan 5. The thermoelectric coolers 3 are equidistantly installed on the outside of the cooling tank 2. One end of the condensation fin of the thermoelectric cooler 3 is located inside the cooling tank 2, and one end of the heat dissipation fin of the thermoelectric cooler 3 is located outside the cooling tank 2. The temperature cooling operation inside the cooling tank 2 is realized by using the condensation fin and the heat dissipation fin of the thermoelectric cooler 3. The air guide groove 4 is opened at the bottom of the inner wall of the cooling tank 2, and the blower fan 5 is installed inside the air guide groove 4. The blower fan 5 is used to blow air into the cooling tank 2 through the air guide groove 4, and at the same time, it is cooled by passing through the thermoelectric cooler 3.

[0033] Referring to Figure 3 and Figure 4 , in one aspect of this embodiment, the crushing mechanism includes a rotating pipe 6, three crushing pipes 7, and two rotary joints 8. The rotating pipe 6 is rotatably connected inside the crushing tank 1 and both the upper and lower ends extend outside the crushing tank 1. The three crushing pipes 7 are equidistantly installed inside the rotating pipe 6. Check valves are provided inside both ends of the crushing pipe 7. By the function of the check valves, the air entering from the top of the rotating pipe 6 can smoothly enter the inside of the crushing pipe 7 through the top of the crushing pipe 7 and finally converge at the bottom of the rotating pipe 6 through the bottom of the crushing pipe 7. The two rotary joints 8 are respectively installed on the top and bottom of the rotating pipe 6. By the function of the rotary joints 8, when the rotating pipe 6 rotates, it will not drive the external structures connected to it to rotate. The crushing pipes 7 and the rotary joints 8 are both communicated with the inside of the rotating pipe 6. By the rotation of the rotating pipe 6, the crushing pipes 7 can be driven to rotate, thereby being able to crush the negative electrode material inside the crushing tank 1 and prevent agglomeration.

[0034] The driving mechanism includes a first gear 9, a motor 10, and a second gear 11. The first gear 9 is installed on the outer side of the top of the rotating tube 6. The motor 10 is installed on the top of the crushing tank 1, and the second gear 11 is installed on the output shaft of the motor 10. The second gear 11 is meshed and connected with the first gear 9. By controlling the operation of the motor 10, the second gear 11 can be driven to rotate, thereby driving the first gear 9 to rotate, and at the same time, the rotating tube 6 can be driven to rotate, thus completing the driving operation.

[0035] A control panel 18 is installed on the outer side of the cooling box 2. The semiconductor refrigeration sheet 3, the air supply fan 5, and the motor 10 are all electrically connected to the control panel 18, and the control panel 18 can be used to control the overall operation of the device.

[0036] Referring to Figure 1 、 Figure 3 and Figure 4 In one aspect of this embodiment, the circulation mechanism includes a first air inlet pipe 12, a return air pipe 13, a cooling tank 14, and a second air inlet pipe 15. The first air inlet pipe 12 is installed between the top of the cooling box 2 and the rotary joint 8 installed on the top of the rotating tube 6. The cooling box 2 and the rotary joint 8 installed on the top of the rotating tube 6 are kept internally connected through the first air inlet pipe 12. When the air supply fan 5 performs an air supply operation into the interior of the cooling box 2 through the air guide groove 4, a part of the air after being cooled by the semiconductor refrigeration sheet 3 will enter the interior of the rotating tube 6 through the first air inlet pipe 12 and the rotary joint 8, and then enter the corresponding interior of the crushing tube 7 from the top of the crushing tube 7 respectively. The return air pipe 13 is installed at the bottom of the cooling box 2. One end of the return air pipe 13 close to the cooling box 2 extends into the interior of the air guide groove 4. The cooling tank 14 is opened in the interior of the crushing tank 1. One end of the return air pipe 13 away from the cooling box 2 extends into the interior of the cooling tank 14. The rotary joint 8 located at the bottom of the rotating tube 6 is kept interconnected with the middle part of the return air pipe 13 through a pipeline. A one-way valve is provided inside the pipeline between the rotary joint 8 located at the bottom of the rotating tube 6 and the return air pipe 13. By the function of the one-way valve, the air inside the rotating tube 6 can smoothly enter the interior of the return air pipe 13 through the pipeline, ensuring that the air inside the return air pipe 13 will not flow back into the interior of the rotating tube 6. At the same time, the air entering the interior of the rotating tube 6 through the first air inlet pipe 12 will flow back into the interior of the air guide groove 4 again through the return air pipe 13, and then undergo cyclic cooling treatment again. The second air inlet pipe 15 is installed between the cooling box 2 and the crushing tank 1. The cooling box 2 and the cooling tank 14 are kept internally connected through the second air inlet pipe 15. When the air supply fan 5 performs an air supply operation into the interior of the cooling box 2 through the air guide groove 4, a part of the air after being cooled by the semiconductor refrigeration sheet 3 will enter the interior of the cooling tank 14 through the second air inlet pipe 15, and also flow back into the interior of the air guide groove 4 again through the return air pipe 13, and then undergo cyclic cooling treatment again.

[0037] Working principle:

[0038] During use, first place the device stably at the designated position, power on the device, and then electrically connect all the electrical components on the device to the control panel 18. At the same time, a temperature sensor can be set inside the pulverizing tank 1 to detect the temperature of the negative electrode material, so as to cooperate with the overall device for use;

[0039] Then, pour the negative electrode material that needs to be cooled into the pulverizing tank 1 through the filling funnel 16. At the same time, control the motor 10 to work through the control panel 18 to drive the second gear 11 to rotate, thereby driving the first gear 9 to rotate. At the same time, it can drive the rotating pipe 6 to rotate. By using the rotation of the rotating pipe 6, the pulverizing pipe 7 can be driven to rotate, so as to pulverize the negative electrode material inside the pulverizing tank 1 and prevent caking;

[0040] At this time, control the air supply fan 5 and the semiconductor refrigeration sheet 3 to work through the control panel 18. Use the air supply fan 5 to blow air into the cooling box 2 through the air guide groove 4. At the same time, it is cooled by the semiconductor refrigeration sheet 3. After being cooled by the semiconductor refrigeration sheet 3, a part of the air will enter the inside of the rotating pipe 6 through the first air inlet pipe 12 and the rotary joint 8, and then enter the corresponding pulverizing pipe 7 from the top of the pulverizing pipe 7 respectively. Finally, it converges at the bottom of the rotating pipe 6 through the bottom of the pulverizing pipe 7, and then flows back into the air guide groove 4 again through the return air pipe 13, and finally undergoes cyclic cooling treatment again;

[0041] At the same time, when the air supply fan 5 blows air into the cooling box 2 through the air guide groove 4, a part of the air after being cooled by the semiconductor refrigeration sheet 3 will enter the inside of the cooling groove 14 through the second air inlet pipe 15, and also flows back into the air guide groove 4 again through the return air pipe 13, and then undergoes cyclic cooling treatment again;

[0042] Thus, it is possible to cool the negative electrode material placed inside the pulverizing tank 1 while pulverizing it, and cool it from both the inside and the outside of the tank body, greatly improving the cooling effect, thus avoiding the phenomenon of caking of the negative electrode material, being beneficial to practical applications, and being able to circulate and cool the air inside the device, thus preventing external hot air from entering the device, and further greatly reducing the energy consumption of the device.
