Abstract

The invention relates to the technical field of powder feeding devices, in particular to a gas explosion type micro powder feeding device and a powder feeding method.The gas explosion type micro powder feeding device comprises a powder conveying pipe and a first driving mechanism, a plurality of powder conveying mechanisms are arranged on the powder conveying pipe in the axial direction of the powder conveying pipe, and each powder conveying mechanism comprises a cylinder arranged on the powder conveying pipe and communicated with the powder conveying pipe; a first valve is arranged between the cylinder body and the powder conveying pipe, a piston matched with the cylinder body is arranged in the cylinder body, the first driving mechanism is in transmission connection with the piston and used for controlling the piston to move in the cylinder body, and a powder storage mechanism and a one-way valve are arranged on the cylinder body. And then the first driving mechanism controls the displacement of the piston and applies pressure to the cylinder body, the first valve is opened, and the powder enters the powder conveying pipe under the action of pressure to realize powder feeding, so that the powder is fed at intervals among a plurality of groups of different powder conveying mechanisms according to requirements, particles are uniformly mixed in a gas explosion manner, and the powder feeding requirement is met.

Description

technical field [0001] The invention relates to the technical field of powder feeding devices, in particular to an air-explosive micro-powder feeding device and a powder feeding method thereof. Background technique [0002] When studying the particle deposition characteristics of gas-solid two-phase flow, most of them involve the problem of micro powder feeding of 0.1-1 g / min and the problem of small particle bonding. In order to ensure the smooth progress of the experiment, uniform and continuous feeding is required. At present, the commonly used powder feeding devices mainly include screw feeding, pneumatic feeding or scraper feeding, etc. However, the existing powder feeding devices have problems such as material bridging, agglomeration or powder accumulation in the feeding structure in the silo. It is difficult to solve, which leads to problems such as uneven or discontinuous powder feeding, which seriously affects the accuracy, stability, continuity and uniformity of ma...
