Clear powder gas passage in mouth leads directly to the porous scaffold of forming board and powder conveying and filtering module；Powder conveys and filtering
Module includes：Porous scaffold, Powder Recovery funnel, Powder Recovery channel, drawer type are without fan-leaf fan, small mesh number mesh screen, big
Mesh number mesh screen forms, and wherein forming board is installed on porous scaffold, and Powder Recovery funnel is equipped with below porous scaffold,
Powder Recovery funnel is connected with Powder Recovery channel, bladeless fan, low mesh number mesh screen, the high mesh number installed successively in recovery approach
Mesh screen is dismountable drawer-type structure；Powder collection module includes：Powder Recovery bag mounting base, powder blocking plate, drawer type can
Powder Recovery bag is dismantled, Powder Recovery bag mounting base is installed on Powder Recovery channel end, and powder blocking plate is installed on Powder Recovery bag
In mounting base, Powder Recovery bag is installed in Powder Recovery bag mounting base.
In said program：Powder cleaning modul is that gas all the way is divided into the controllable two-way gas of start and stop using solenoid valve,
Gas enters the clear powder gas passage in powder-feeding nozzle, after act on forming board and porous scaffold.
The powder conveying of the metal powder recycling device for laser metal forming process is with filtering module by powder
Mesh screen etc. of the drawer type installed successively from top to bottom in end recycling funnel, Powder Recovery channel without fan-leaf fan, filtering powder.
The powder collection module of the metal powder recycling device for laser metal forming process is by being installed on
The Powder Recovery bag mounting base of Powder Recovery channel end, powder blocking plate, Powder Recovery bag composition, powder are conveyed and are filtered through powder
Enter Powder Recovery bag after module or is stranded under the action of powder blocking plate in Powder Recovery bag mounting base.
Present invention major advantage compared with existing equipment has：
For the present invention using the powder on clear powder gas cleaning work platform and substrate, avoiding manual cleaning powder may be to people
Body causes damages.
The present invention uses no fan-leaf fan to provide power for powder transmission process, the small, energy consumption compared with using wind turbine
It is low.
The present invention using drawer type can the powder collection mode that is combined of Powder Recovery bag and powder blocking plate, avoid removal process
Powder unrestrained and pollution.
