Description

Technical Field

[0001] This utility model relates to the technical field of carbon fiber powder production equipment, specifically a carbon fiber powder production equipment. Background Technology

[0002] In the process of producing carbon fiber powder, carbon fiber needs to be crushed. After crushing and filtering, carbon fiber powder can be obtained. According to the carbon fiber powder preparation device proposed in patent authorization announcement number: CN217189947U, multiple steel balls are arranged in the powder preparation tank, and the powder preparation tank is connected to a rotating shaft. When the rotating shaft drives the powder preparation tank to rotate, the steel balls in the powder preparation tank will move freely. When the steel balls collide and hit each other, they will squeeze and grind the carbon raw material, thus producing uniform carbon fiber powder.

[0003] However, in the existing powdering process, carbon fibers are pulverized by the collision of steel balls. But as the carbon fibers are gradually pulverized, the fixed space inside the chamber increases the range of motion of the steel balls, leading to a longer time interval between their collisions, which affects pulverization efficiency. Furthermore, it is difficult to separate the sized carbon fiber powder from the carbon fibers during pulverization. Therefore, improvements to the existing technology are needed.
