Description
Technical field
The present invention relates to a kind of micro-nano powder powder feeder, is in particular a kind of micro-nano that uninterrupted powder feeding can be achieved
Ground rice body powder feeder.
Background technology
Powder feeder is the core component of the powder processing equipments such as thermal spraying, cold spraying, deposition, spheroidizing of powder, powder feeding process
Continuity and uniformity will directly affect the stability of powder process.Currently used powder feeder is broadly divided into rotating disk
Formula powder feeder, boiling bed powder feeder, screw powder feeder, scrape disc type powder feeder, drum type powder feeder and Electromagnetically vibrating and send
Powder device.
The powder feeder used currently on the market has that " Hu Xiaodong, Ma Lei, Luo Cheng laser claddings are synchronous for document
Present Research [J] aero-manufacturing technologies of powder feeder, 2011 (9):The structure of rotating disc type powder feeder is described in 47-49 ".It is main
To be made up of powder hopper, powder disk, starch sucking nozzle and flour extraction pipe.During work, powder falls into powder disk by self gravitation effect from powder hopper, and
Delivered in the case where motor rotates induced effect at powder absorbing pipe, powder delivers to flour extraction pipe under gas pressure effect.Rotating disc type powder feeder
Powder pushing precision is high, but requires that powder has preferable mobility, and powder has pulsation phenomenon in conveying, and precision is difficult into one
Step lifting.In addition, rotating disc type powder feeder can not be applied to the micro-nano powder that powder size is tiny, mobility is poor.
