Sieve, then fall into feeding barrel 3, it recycles repeatedly；
When 8 feedback signal of the Material Sensor alarm at 3 top of feeding barrel in S3, illustrate that powder has been filled in powder feeding bucket, if
It is standby to shut down；Or in shaping axle 22, receipts powder bucket after powder absorption, equipment is turned off manually in operator, and closes each valve,
Feeding barrel 3 and equipment are disconnected, pitches out to be installed in increasing material manufacturing equipment by feeding barrel 3 with fork truck and carries out working standby.
Embodiment 2
In Fig. 6, for the non-powder falling formula increasing material manufacturing equipment that cannot be exactly matched with present device or any do not join
With powder circulation process, only need to sieve the end being collected into when, need in the Equipment Foundations of embodiment 1
The material-receiving system and feed system are removed, screening system is retained；Then dress is put into the position for placing vaccum storage bucket 1 originally
There is the upper power collecting bucket 14 of powder；The power collecting bucket 15 in the case where the position for placing powder feeding bucket originally is placed；The upper end of screening hopper 2 and upper storage
The lower end of powder bucket 14 is connected by hose；The lower end of screening hopper 2 is connect with the upper end of lower power collecting bucket 15 by hose；Exist simultaneously
Screening system gas control module 16 is set on the multi-purpose stand 13, the powder sieving of example 1 is implemented, collecting equipment repacks into
It is independent screening plant.
It is the screening plant control flow after repacking in Fig. 7:
S1, starting up, inert gas intake valve and outlet valve are opened, and are started progress gas inside screening system and are set
It changes；After sieving the lambda sensor in powder module and feeding back oxygen content to setting value such as 2%, inert gas intake valve is closed, while sieving powder
