Anti-explosion powder supply device

Abstract

The invention relates to an anti-explosion powder supplying device and pertains to the field of flow field testing. The anti-explosion powder supplying device has a cylinder body, the upper port of which is provided with an inner convex edge; an anti-explosion opening is arranged below the inner convex edge; the cylinder body between the inner convex edge and a gas-collecting skirt is provided with at least two ribs; the gas-collecting skirt is fixedly connected with one end of a feed pipe; the feed pipe is provided with a discharge pipe and the other end of the feed pipe is provided with an end cap; the lower port of the cylinder body is provided with an outer convex edge connected with a base; the bottom of the cylinder body is provided with an intake pipe; the intake pipe arranged in the cylinder body is provided with a fluidized pipe; and the top of the intake pipe is provided with a pipe plug. The device can provide required trace particles for a tested flow field evenly in time or put powder particles in a known space evenly, meet air-carrying particles with rather high pressure, ensure the safe running of the air-carrying particles, prevent the blocking of particles caused by cementation and solve the problem that the quality of powder supply is affected by the flowing out of particles in strands, thus improving the precision of the powder supply, being capable of controlling the flow speed and flow quantity of the particles evenly and effectively and ensuring the safe generation of powder supply.

Description

1. Technical field [0001] The patent of the invention relates to an explosion-proof powder supply device, which belongs to the field of flow field testing. 2. Background technology [0002] In the laser measurement research of gas flow, liquid particles or solid particles are generally used as tracer particles. For solid particles, tracer particles can be obtained by atomizing a solution or liquid with suspended solid particles, or vibrating a fine powder of particulate material with air in a fluidized bed. Usually a good particle generator can generate high-quality tracer particles and improve the quality and accuracy of the measurement signal. An ideal particle generator should preferably produce a monodisperse suspension. However, such particles are not easy to generate in the low flow rate range of small instruments, nor is it easy to generate small amounts of uniform particles. 3. Contents of the invention [0003] The object of the present invention is to provide ...
