A kind of solid raw material pretreatment device and method for nanocomposite preparation

Abstract

The invention discloses a solid raw material pretreatment device and method for preparing nanocomposite materials, comprising an inner box and an outer box arranged outside the inner box, the upper end of the inner box is provided with a drive motor through a fixing frame, and the drive motor The output end is connected to the upper end of the rotating shaft, and the lower end of the rotating shaft runs through the upper and lower end surfaces of the inner box; the lower end surface of the outer box is provided with a discharge port, and the discharge port is equipped with a movable sealing plate for blocking. The right end is connected to a push cylinder for driving it to move left and right. The bottom of the outer box where the discharge port is located is provided with a collection bucket for collecting materials. This invention is designed for the disadvantages of existing devices and realizes the circular screening of materials. , to avoid the waste of materials, the air selection and the mesh screen are combined in the screening to ensure the screening effect, and the screened impurities can also be removed to avoid the accumulation of impurities, which is very practical.

Description

technical field [0001] The invention relates to the technical field of nanomaterial processing equipment, in particular to a solid raw material pretreatment device and method for preparing nanodiamond composite materials. Background technique [0002] Diamond is commonly known as "diamond". That is what we often call the original body of diamond. It is a mineral composed of carbon element, which is an allotrope of carbon element. Diamond is the hardest substance naturally occurring in nature. Diamonds are used in a wide variety of applications, such as: handicrafts, cutting tools in industry. Graphite can form synthetic diamond under high temperature and high pressure. It is also a precious gemstone. Purified nano-diamond is a kind of diamond. Nano-diamond is prepared by mixing nano-materials and diamond principles. The purity determines the quality. Impurities other than raw materials need to be screened out. It can screen out one of solid particles or soft impurities, ...

AI Technical Summary

Problems solved by technology

It is also a precious gemstone. Purified nano-diamond is a kind of diamond. Nano-diamond is prepared by mixing nano-materials and diamond principles. The purity determines the quality. Impurities other than raw materials need to be screened out. It can screen out one of solid particles or soft impurities, and the screening effect is poor

[0003] In view of the above problems, the patent announcement number CN209020774U now discloses a raw material pretreatment device, which is difficult to remove unqualified impurities when screening. In addition, the screening efficiency of this plate-shaped filter screen is low, which is not conducive to Provides preprocessing efficiency
