Technical field
The present invention relates to 3D printing associated machines fields, more particularly to one kind in 3D printing purification system for recycling
Dedusting filter device.
Background technology
During metal 3D, the molding metal powder of laser printing be easy under the high temperature conditions with the oxygen in air
Oxidation reaction occurs, generates a large amount of flue dust, it is therefore desirable to be passed through the inert gases such as nitrogen or argon gas in closed molding room
Gas shield is carried out to metal laser printing shaping process, prevents metal powder high-temperature oxydation.But still have a small amount of flue dust production
Raw, these flue dust can be attached under the disturbance of thermal current on window mirror, or be diffused on laser formation face, and influence is directly connect
Laser emission goes out energy, and the quality of metal forming part is rung from face.If the protective gas with flue dust is directly sucked into
Outside type room, the waste of protective gas is not only caused, but also serious pollution is caused to environment.Therefore, indoor to being molded
Protective gas, which carries out circularly purifying recycling, can effectively reduce printing cost, while generate smaller pollution to environment.
Existing recyclegas purification mostly uses the filter core mounting structure that fine filter adds high efficiency particulate air filter greatly, rectangular
Filter core size is larger, is placed in a welded seal babinet, and chamber door can be opened, with rubber seal rings for seal, for replacing filter core.
This filter apparatus configuration is more complex, and manufacturing cost is higher, and chamber door rubber seal aging is also easy to produce gas leakage, causes work system
Oxygen content increases.Simultaneously because filter core has certain thickness, filter core inside fold is more, and element back-wash filter effect is bad, not reproducible
It utilizes, higher operating costs, and filter core after just stopping using, has certain temperature, met in hard stop replacement process empty
Gas is also easy to produce dieseling, therefore, relatively high excellent using having in its cost per unit of the efficient filter core of cylindrical shape and recycling
Gesture.
