Description

Technical Field

[0001] This utility model relates to the field of nanomaterial production technology, specifically to a raw material grinding device for nanomaterials. Background Technology

[0002] Nanomaterials are materials that have at least one dimension in three-dimensional space at the nanoscale (1-100nm) or are composed of them as basic units. This is roughly equivalent to the scale of 10-1000 atoms packed together. When producing nanomaterials using physical pulverization methods, the raw materials must be crushed. Due to the size characteristics of nanomaterials, the raw materials must be ground finely enough.

[0003] An existing patent (publication number: CN213557410U) discloses a crushing device for the production of nanomaterials. The patent states that the device includes a fixed base plate, a production box above the fixed base plate, a motor box fixed in the middle of the top of the production box, a motor inside the motor box, an output shaft of the motor extending through the top of the production box and connected to a crushing component, a feed hopper penetrating the outer wall of the top of the production box at the front of the top of the production box, a filter screen in the middle of the inner cavity of the production box, and a discharge hole in the middle of the lower end face of the production box, with a discharge pipe inside the discharge hole. The invention utilizes the interaction between the grinding ball and the annular crushing disc at the lower end of the connecting rod to facilitate more thorough crushing of the raw materials. Furthermore, the entire grinding process of the raw materials is carried out inside the production box, avoiding the mixing of external impurities into the raw materials and improving the quality of the produced nanomaterials.

[0004] While the aforementioned patent can perform preliminary crushing and filtration of the added nanomaterials and improve grinding efficiency, its fixed filter screen can cause clogging during material feeding, making it impossible to clean the filter screen and thus affecting the grinding effect of the nanomaterials. Therefore, a raw material grinding device for nanomaterials is proposed. Summary of the Invention

[0012] As a further preferred embodiment of this technical solution: the support is U-shaped, and the width of the top plate is smaller than the diameter of the feeding hopper.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model drives the rotating shaft and grinding balls to rotate by starting the drive motor. At this time, the filter plate is rotated by the flat key, which can screen nanomaterials.
