Piece can damage laser head when serious, while smog can also pollute the indoor equipment of molding and metal powder material.Unsealed
Smog not only pollutes environment but also endangers personnel health in the printer course of work.After the completion of print job, it is in molding room
The discarded impurity generated in the powder of sintering doped with a large amount of sintering, to save material, it is necessary to remaining powder indoor to molding
Removal of impurities is filtered with secondary use.
Notification number discloses one kind for the Chinese utility model patent CN201620644694.7 of CN205763853U and is used for
The gas circulating purifying device of 3D printing equipment forming atmosphere is mainly separated by the way that cyclone type particle is arranged on circulation line
Device, filter core group reach separation and purification to smog and dust in 3D printer molding room, although having reached to the net of smog
Change effect, but any recovery processing is not done to the powder after separation, causes unnecessary waste.
The Chinese utility model patent CN201720919623.8 that notification number is CN207207146U discloses a kind of 3D and beats
Print machine powder recovering device, the main cooperation for passing through absorption tube and vibration screen, reaches the filtration, purification to remaining metal powder.
The difficulty for reducing manual recovery powder, saving the time improves efficiency, but does not do any processing to smog, and needs another
Outer increase equipment.
In conclusion can only be purified in the prior art to the smog of 3D printer or need in addition to increase equipment pair
Powder after printing is filtered processing.
Utility model content
The purpose of the utility model is to provide a kind of filtration system of 3D printer, filtration system both can be to 3D printing process
In smog purified, while the powder after the completion of printing can be recycled.
The utility model utility model design be in filtration system be arranged solid gas separator, powder filter device and
Gas cleaning plant purifies smog by gas cleaning plant by the separation of solid gas separator realization powder and gas,
Metal powder is filtered by powder filter device.
The embodiment of the utility model includes a kind of filtration system of 3D printer, including vacuum cycle pump 8, blower 13, sky
Gas purifier 12 and cyclone separator 9, further include powder filter device, and the powder filter device is vibrating screen 10；It is described true
The outlet of idle loop pump 8 connects the import of cyclone separator 9 by pipeline, and the solid outlet of the cyclone separator 9 connects vibration
The import of dynamic sieve 10, the gas discharge mouth of cyclone separator 9 connect the entrance of air purifier 12, air cleaning by pipeline
The outlet of device 12 connects the entrance of blower 13 by pipeline.
In actual use, in the course of work of 3D printer, the separation of powder and gas is realized by cyclone separator 9,
Powder enters powder filter device, filters out the impurity generated when sintering, and gas enters air purifier, completes purification heel row
Out.It is sent into cyclone separator 9 after forming indoor powder after the completion of printing, powder is entered by the solid outlet of cyclone separator 9
Powder filter device, filtering powder away in impurity i.e. be recycled utilize again.
Technical solution disclosed by the utility model increases powder filter on the basis of existing technology compared with prior art
Device, powder raw material is recovered by filtration after the completion of printing, structure simply can in print procedure to smog in Photocopy Room into
Row purification, can be recycled powder after having printed.
