Description

TECHNICAL FIELD

[0001] The utility model relates to electrode raw material processing equipment technical field, concretely relates to a kind of porous carbon electrode raw material grinding equipment. BACKGROUND

[0002] Porous carbon electrode is a kind of electrode made of carbon material with high specific surface area and abundant pore structure, which exhibits important application value in energy storage and conversion devices such as batteries, supercapacitors and electrocatalysis due to its excellent electrical conductivity and excellent electrochemical activity. Porous carbon electrode raw material refers to the raw material used to prepare porous carbon electrode. These materials usually have rich carbon content and the potential to form porous structure, such as activated carbon, graphene-based carbon materials, biomass materials (such as waste lentil straw), etc. After carbonization, activation and other process treatments, they can be converted into porous carbon electrode materials with controllable pore size and pore distribution, high specific surface area and excellent electrochemical performance.

[0003] However, when grinding electrode raw material into powder for the next step of processing, in order to ensure the accuracy of the powder particles and improve the processing quality and efficiency of the powder, most of the existing grinding machines have a filter frame inside.

[0024] In one embodiment, when the storage tank 3 is installed, the storage tank 3 can be placed on the upper end face of the lower end plate 21 and directly below the grinding machine 1, then the support feet 36 at the four corners of the storage tank 3 are screwed, the support feet 36 are displaced downward through the threaded grooves 361 in the inner cavities of the support feet 36 on the outer wall of the threaded rods 35 and are in close contact with the upper end face of the lower end plate 21, the storage tank 3 is lifted and displaced upward, the storage tank 3 is clamped at the bottom of the grinding machine 1 through the recesses 311 on the top supporting plates 31 of the storage tank 3, the installation of the storage tank 3 and the filter frame 32 thereon is completed, the storage tank 3 and the filter frame 32 thereon can be used to filter and store the powder after the grinding machine 1 grinds, and the grinding quality of the electrode raw materials is ensured.

[0025] In one embodiment, when the filter frame 32 is installed, the filter frame 32 can be directly inserted into the storage cavity 301 through the through groove 302, and then the U-shaped baffle 33 is pushed upward by the elastic force of the reset spring 34 to tightly press the filter frame 32 at the upper end of the through groove 302, thereby limiting the position of the filter frame 32 and preventing the filter frame 32 from shaking.
