Powder cleaning module comprises gas piping, two-bit triplet electricityMagnet valve, powder-feeding nozzle composition, wherein the clear powder gas in road is divided into two-way gas and enters powder-feeding nozzle after magnetic valveClear powder gas passage, the straight-through forming board of clear powder gas passage in powder-feeding nozzle and powder are carried and are filtered mouldThe porous workbench of piece; Powder is carried with filtering module and is comprised: porous workbench, Powder Recovery funnel, powderRecovery approach, drawer type without fan-leaf fan, little order count mesh screen, large order is counted mesh screen composition, wherein forming board peaceBe loaded on porous workbench, porous workbench below is provided with Powder Recovery funnel, Powder Recovery funnel and powderRecovery approach be connected, in recovery approach, be provided with successively dismountable drawer type without fan-leaf fan, little order count mesh screen,Large order is counted mesh screen; Powder collection module comprises: Powder Recovery bag mount pad, powder blocking plate, the detachable powder of drawer typeEnd collection bag, Powder Recovery bag mount pad is installed on Powder Recovery channel end, and powder blocking plate is installed on Powder RecoveryOn bag mount pad, Powder Recovery bag is installed on Powder Recovery bag mount pad.
In such scheme: powder cleaning module is to adopt magnetic valve Jiang Yi road gas to be divided into the controlled tow channel gas of start and stopBody, gas enters the clear powder gas passage in powder-feeding nozzle, after act on forming board and porous workbench.
The powder of the described metal powder recycling device for laser metal forming process is carried and filtering moduleBy in Powder Recovery funnel, Powder Recovery passage from top to bottom successively install drawer type without fan-leaf fan, filtrationThe compositions such as the mesh screen of powder.
The powder collection module of the described metal powder recycling device for laser metal forming process is by pacifyingBe loaded on Powder Recovery bag mount pad, powder blocking plate, the Powder Recovery bag composition of Powder Recovery channel end, powder warpAfter powder conveying and filtering module, enter Powder Recovery bag or under the effect of powder blocking plate, be stranded in Powder Recovery bagIn mount pad.
The present invention's major advantage compared with existing equipment has:
The present invention adopts the powder on clear powder gas cleaning work platform and substrate, has avoided manual cleaning powder possibilityHuman body is worked the mischief.
The present invention adopts without fan-leaf fan and provides power for powder course of conveying, with adopt blower fan phase specific volume little,Energy consumption is low.
The present invention adopts the drawer type can Powder Recovery bag and the powder collection mode that combines of powder blocking plate, avoids reclaimingUnrestrained and the pollution of the powder of process.
