Problems solved by technology

[0005] The existing nano-scale raw material grinding device for lithium batteries still has some shortcomings. Due to the high speed of the device during operation, not only is it easy to cause the temperature of the internal grinding parts to be too high, resulting in a reduction in the life of the device, but also the extension rod is easy to contact with the raw material under high-speed rotation. The rapid impact occurs, resulting in excessively high temperatures and damage to the properties of the raw materials, resulting in a problem of lower quality of the prepared product

Embodiment 1

[0030] Such as Figure 1 to Figure 2As shown, a high heat dissipation lithium battery nano-scale raw material grinding device described in the embodiment of the present invention includes a base 1, a drive box 2 is fixedly installed on the top of the base 1, and one side of the drive box 2 A grinding tank 3 is provided, and the grinding tank 3 includes a central rod pin 8 and an outer casing 5, and one end of the central rod pin 8 is fixedly mounted with a motor 7, and the motor 7 is located inside the drive box 2, and the central rod Grinding rods 6 are fixedly installed on the outside of the pin 8, and several groups of extension rods 10 are fixedly installed on the outside of the grinding rod 6. Cooling fan 4, the cooling fan 4 is located on the outside of the outer casing 5, and the inner side of the center rod pin 8 is provided with a heat transfer assembly, when working, put the raw material to be ground into the grinding tank 3, and the starting motor 7 drives the cente...

Embodiment 2

[0040] Such as Figure 5 As shown in Comparative Example 1, another embodiment of the present invention is as follows: the outside of the grinding mesh 12 is provided with several sets of permeable grooves 21, and the permeable grooves 21 are arranged in a narrow shape with wide ends at both ends and a narrow center in the middle. Moreover, both sides of the grinding net 12 are fixedly installed with several groups of protrusions 22. When working, the two ends of the outer side of the grinding net 12 pass through the groove 21 and the narrow shape is set in the middle, so that the raw material can enter it more easily. It will be squeezed and shaken, and then shaken and broken up at the exit, so as to further increase the crushing effect on raw materials.

[0041]When working, put the raw materials to be ground into the grinding tank 3, start the motor 7 to drive the center rod pin 8 and the grinding rod 6 to rotate, through the rotation friction, impact and vibration, the raw...

Abstract

The invention belongs to the field of lithium battery preparation, and particularly relates to a high-heat-dissipation nanoscale raw material grinding device for lithium batteries, which comprises a base, a driving box is fixedly mounted at the top end of the base, a grinding tank is arranged on one side of the driving box, and the grinding tank comprises a central rod pin and an outer wrapping cylinder. A motor is fixedly installed at one end of the center rod pin and located on the inner side of the driving box, a grinding rod is fixedly installed on the outer side of the center rod pin, a cooling fan and a heat transfer assembly are arranged, the heat transfer assembly can absorb and transfer high temperature generated by the grinding rod, and the surface temperature of the grinding rod is reduced; the heat dissipation fan is fixedly connected with the center rod pin, so that high-speed rotation of the center rod pin can be inherited, the heat dissipation fan can conduct physical cooling through rotation, the surface temperature of the grinding rod is effectively reduced through mutual cooperation of the heat dissipation fan and the heat transfer assembly, the service life of the device is greatly prolonged, and the grinding efficiency is improved. And meanwhile, the quality of finished products is effectively improved.

Description

technical field [0001] The invention belongs to the field of lithium battery preparation, in particular to a high heat dissipation nanoscale raw material grinding device for lithium batteries. Background technique [0002] Lithium battery is a kind of disposable battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Compared with ordinary lead-acid batteries, lithium battery has the advantages of larger capacity and smaller volume. [0003] In the production process of lithium batteries, the raw materials need to be crushed. Since the raw materials in the lithium battery will expand and shrink during the working process, it is easy to cause the battery as a whole to be damaged. The best way is to nano-grind the raw materials. [0004] A Chinese patent with a publication number of CN108615852A discloses a lithium battery production process in which the graphite raw material is screened for impurities; the...
