Amorphous boron powder pretreatment device based on layer-by-layer staggered stacking

Abstract

The invention relates to the field of amorphous boron powder, in particular to an amorphous boron powder pretreatment device based on layer-by-layer staggered stacking. The technical problem is to provide the amorphous boron powder pretreatment device based on layer-by-layer staggered stacking. According to the technical scheme, the amorphous boron powder pretreatment device based on layer-by-layer staggered stacking comprises a bottom frame, a staggered feeding unit, a layer-by-layer laying unit and a compacting unit; the bottom frame is connected with the staggered feeding unit; the bottom frame is connected with the layer-by-layer laying unit; the bottom frame is connected with the compaction unit; and the staggered feeding unit is connected with the layer-by-layer laying unit. According to the method, the boron gangue powder and the magnesium shavings are laid in a staggered and laminated manner, so that the boron coal powder and the magnesium shavings can be in contact with each other to the greatest extent, the boron gangue powder and the magnesium shavings can be subjected to oxidation-reduction reaction conveniently, the purity of the produced amorphous boron powder can be improved, and the particle size is smaller and uniform after full reaction.

Description

technical field [0001] The invention relates to the field of amorphous boron powder, in particular to an amorphous boron powder pretreatment device based on layer-by-layer staggered stacking. Background technique [0002] Amorphous boron is stable in air at room temperature. Amorphous boron powder has a large specific surface area and a high calorific value of combustion. It is widely used in military, aerospace and automotive fields. At present, amorphous boron is produced at high temperatures, but this The amorphous boron produced by this method is easy to be further oxidized, resulting in low purity and uneven strength. [0003] Chinese patent CN104402014A aims at the existing problems of amorphous boron powder production, discloses a production process of amorphous boron powder, which overcomes the magnesia thermal reduction method in the prior art by stacking boron anhydride powder and magnesium shavings The obtained amorphous boron is easy to be further oxidized, resu...

Problems solved by technology

[0006] In order to overcome the obvious difference in the properties of boric anhydride powder and magnesium shavings in the production of amorphous boron powder, when they are stacked layer by layer, the laying of boric anhydride powder and magnesium shavings is uneven, which will lead to the particle size of amorphous boron It will be uneven, which will affect the combustion performance of the product, and when the boric anhydride powder and magnesium shavings are processed continuously in batches, the processing of the boric anhydride powder and magnesium shavings will be more cumbersome, and the working efficiency will be greatly limited. Technical problem: Provide a pretreatment device for amorphous boron powder based on layer-by-layer staggered stacking
