Problems solved by technology

[0002] At present, the commonly used powder conveying and feeding devices do not get effective fluidization before the powder enters the supply system, which often causes problems such as uneven powder density and poor fluidity, and sometimes even causes the powder to fail to flow smoothly. Enter the conveying device, or cause fluctuations in the amount of material during the feeding process and damage the downstream process

Abstract

The invention relates to a powder supplying system. The powder supplying system comprises a fluidization system, a buffer bin and a mixing chamber; the fluidization system comprises two or more stages of fluidization combination devices and an air storage tank; the two or more stages of fluidization combination devices are longitudinally and fixedly arranged on the outer wall of the buffer bin at intervals, and each stage of fluidization combination device is connected with an air outlet of the air storage tank sequentially through a flow meter and a flow adjusting valve; an air inlet of the air storage tank is connected with external compressed air through a pressure reduction valve and a drain outlet of the air storage tank is connected with an external sewage storage device through a sewage draining valve; and a discharging opening of the buffer bin is connected with the mixing chamber. It can be ensured that power continuously and stably enters an external conveying pipeline.

Description

technical field [0001] The invention relates to a feeding system, in particular to a powder feeding system. Background technique [0002] At present, the commonly used powder conveying and feeding devices do not get effective fluidization before the powder enters the supply system, which often causes problems such as uneven powder density and poor fluidity, and sometimes even causes the powder to fail to flow smoothly. Enter the conveying device, or produce fluctuations in the amount of material during the feeding process and damage the downstream process. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide a powder feeding system, which can ensure that the powder enters the external conveying pipeline continuously and stably. [0004] In order to achieve the above-mentioned technical purpose, the present invention adopts the following technical solutions: a powder feeding system, which includes a fluidizati...
