Description
Technical field
The invention belongs to 3D printer technical fields, specifically, the present invention relates to a kind of smoke dust filters.
Background technology
With the development of science and technology, 3D printer occurs gradually in the visual field of people, currently, 3D printing technique is base
The process of entity component is manufactured in powder bed process, selective laser melting, which is SLM, is directly melted using high energy beam laser
Complicated three-dimensional geometry body is converted into two dimensional surface and manufactured by metal powder, SLM, and manufacturing cost depends not only on the complexity of part
Shape, the equipment for also manufacturing part, the method which substantially applies is as follows, power spreading device layer overlay metal powder on powder cylinder
End, laser beam under control of the computer, according to molded part cross sectional shape, carry out selective scanning to powder, make scanning area
Interior powder bonding or fusing, obtain the monolayer shape of molded part, and then powder cylinder declines the distance of a thickness, power spreading device weight
New powdering continues next layer of molding, is so successively superimposed, the final metal parts for obtaining geometry in particular.
In part sintering process, laser will produce many metal fumes when being heated to metal powder, and metal fumes can be right
Laser scanning operation impacts, and reduces the Forming Quality of part, and existing 3D printer is generally furnished with smoke dust filter,
The gas constantly sucked in shaping box simultaneously when forming parts is then discharged out, and the flue dust wherein generated is absorbed, existing mistake
It is to improve filter effect to be equipped with multiple filtration net to filter device, and flue dust is tiny solid particle, when first layer filter screen
When adsorbing excessive soot dust granule, the permeability of filter screen declines immediately, and gas is reduced by speed, and filter effect declines, this
When need worker to clean or replace filter screen, but in addition to first layer filter screen, subsequent filter screen is less due to adsorbing
Soot dust granule, suction-operated is still preferable, but due to the gas percent of pass of first layer filter screen decline, lead to subsequent mistake
Strainer can not play whole effects, cause worker more frequent to the processing of filter screen.

3D printer opens aspiration pump when working, aspiration pump sucks gas from air inlet pipe, and gas passes through filter screen one and filter screen two
Absorption after enter adsorption box in, filter screen one and filter screen two adsorb most soot dust granule, remaining a small amount of flue dust
Particle dissolves in adsorbing medium, is finally reentered in shaping box from escape pipe, during adsorbing flue dust, most of gas
First layer filter screen two is first passed around, partial gas passes through from the air passing hole of first layer filter device two, when the mistake of first layer
Strainer two adsorb flue dust it is excessive when, gas is started slack-off by speed, and most of gas starts from first layer filter device two
Air passing hole move downward, then gas is absorbed and filter by the filter screen two on second layer filter device two, similarly
Partial gas enters lower section from the air passing hole on second layer filter device two, then by filter screen a pair of gas of adsorbent equipment one
Body is absorbed and filter, and one both ends pore-free of filter device passes through, and makes it that can only pass through from filter screen one, when the filtering of the second layer
Net two due to absorption flue dust is excessive and when gas percent of pass reduces, the gas of the air passing hole of second layer filter device two passes through speed
Start the air velocity transducer for increasing, and being disposed below and is used for detecting its gas by speed, when its speed is more than to require speed
When, illustrate that the filter screen two of second layer filter device two can not work normally due to adsorbing excessive flue dust, gas can only be from mistake
Stomata flows, and air velocity transducer feeds back information to alarm lamp, and worker has found that alarm lamp lights Shi Zexu to the mistake in Rose Box
Strainer two and filter screen one are cleared up, and filter screen two gives full play to its strainability until being unable to normal filtration work at this time
Industry, this filter device can fully play the filtration of all filter screens compared to traditional filtering device, until all filterings
The strainability of net cannot meet the processing for being filtered net when normal operation again, reduce and frequently cleaned to filter device
Number.
