A powder feeding device and method

Abstract

The embodiment of the invention discloses a powder feeding device and method, including a material storage mechanism and a stirring and feeding mechanism, the storage mechanism is used to provide powder to the stirring and feeding mechanism; A powder stirring component and a powder discharging component, wherein the powder stirring component is used for loosening the powder, and the powder discharging component is used for transferring the loose powder to the outside of the stirring and feeding mechanism. The powder feeding method includes conveying the powder after being loosened. By sequentially connecting the powder stirring assembly and the powder discharging assembly along the discharge direction, it is convenient for the powder to be pre-stirred during the falling process of the powder stirring assembly. When it is in the material component, through the further stirring of the powder material mixing component, the inside of the powder material will be relatively rotated to realize the loosening of the powder material, which is convenient for its feeding, and the loose powder material is evenly distributed, so that the feeding amount is consistent and effectively avoids jamming death and other issues.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of powder feeding, and in particular to a powder feeding device and method. Background technique [0002] During the production of gypsum boards, several powdery additives need to be added to gypsum powder for mixing, so the stability of the powder adding equipment will greatly affect the quality of gypsum boards. [0003] Powder adding equipment currently in use such as figure 1 As shown, the powder is stored in the silo (reference number 10), and is scraped and fed into the screw feeder (reference number 30) through a scraper (reference number 20) during use to realize Quantitative addition of powder; however, this set of equipment is prone to agglomeration of materials in the silo during use, and the feed volume of the scraper is difficult to control. When the feed volume is greater than the feed volume of the screw conveyor, it is prone to jamming and other situations. Conten...
