Device of feeding solid powder into high-speed air flow

Abstract

The invention provides a device of feeding solid powder into a high-speed air flow. The device mainly comprises a supersonic spray pipe, a lateral annular pore plate gas inlet barrel, an auxiliary feeding nozzle, a charging cabin, a feeding pipe and the like. Gas enters through the lateral annular pore plate gas inlet barrel and carries materials fed from the charging cabin and the feeding pipe to collide with a target if being accelerated by the supersonic spray pipe, and the auxiliary feeding nozzle can feed in an auxiliary manner, so that the problem that a powdery material which is fed is likely to block is solved.

Description

technical field [0001] This patent relates to a device, in particular to a device for sending solid powder into a high-speed airflow. Background technique [0002] Low-heat solid-state reaction synthesis technology is a new material preparation technology that has developed rapidly in recent years. Its essential feature is energy transfer at room temperature or low temperature, that is, through mechanical grinding and other methods, mechanical energy is introduced into the powder reactant system and transformed into The chemical energy of the reaction system, so as to realize the solid phase synthesis at room temperature. From the perspective of material preparation technology, the necessary condition for realizing low-heat solid-phase synthesis reaction is to introduce mechanical energy into the system to induce the reaction. The study found that the use of high-speed airflow acceleration technology can also feed mechanical energy into the reaction system, and the energy d...
