Description

Vacuum laser SLM printer vacuum dust filter unit

Technical field

This utility model relates to a kind of vacuum laser SLM printer, particularly to one Vacuum laser SLM printer vacuum dust filter unit.

Background technology

The shaping house dust of vacuum laser SLM printer is big, existing vacuum dust mistake Filter can only provide disposable filtering dust, and method is the method spread by micropore, Forevacuum time lengthening, can only remove vacuum chamber eolian dust, beats for SLM metal Print machine, owing to constantly producing new dust in work process, is carried out along with SLM prints, Metal dust, flue dust constantly produce, it is clear that not all right by micropore diffusion method, normal with other Rule dedusting method, as centrifugal, then flow is the least, is difficult to produce enough centrifugal force, By filter screen (paper) formula, then resistance is too big, inapplicable diffusion pump or the work of molecular pump Requirement.

Utility model content

In order to make up above deficiency, this utility model provides a kind of vacuum laser SLM Printer vacuum dust filter unit, this vacuum laser SLM printer vacuum dust-filtering Device have employed maze-type structure and achieves the abundant filters to dust, and to air-flow Resistance is little, simple in construction, economical and practical.

This utility model be the technical scheme is that one to solve its technical problem Plant vacuum laser SLM printer vacuum dust filter unit, including shell, described shell It is formed with import on end wall, another end wall of shell is formed with outlet, inside shell Intersect respectively on two relative sidewalls and be provided with some groups of dividing plates, between dividing plate, form labyrinth Formula circuitous channel, these labyrinth type circuitous channel two ends respectively with the inlet and outlet of shell Connection.

As the further improvement of utility model, each dividing plate going out towards shell described Mouth direction is obliquely installed.

As the further improvement of utility model, described dividing plate with and side wall of outer shell vertical Plane included angle be 10 °～85 °.

As the further improvement of utility model, described dividing plate two-by-two be arranged in parallel.

As the further improvement of utility model, described dividing plate is along air current flow direction The back side is fixed with extension fluorubber plate.

As the further improvement of utility model, described shell includes first and second housing, First and second housing can be sealedly and fixedly connected, and the first case inside wall is fixed with The dividing plate that some rows extend in the same direction, the second case inside wall is fixed with some rows with The dividing plate that first case inside wall upper spacer is oppositely extending, the first case inside dividing plate with Second case inside dividing plate intersects the most one by one, the first case inside wall upper spacer end with Between second case inside wall formed space, the second case inside wall upper spacer end with Also space is formed between first case inside wall, adjacent on first and second case inside wall Dividing plate between also form space.

As the further improvement of utility model, described first and second housing two end portions Not forming semi-circular cut-out, the semi-circular cut-out at first and second housing both ends is just spliced Become the inlet and outlet of filter.

As the further improvement of utility model, described shell be column type structure or Square chest type structure.

As the further improvement of utility model, if arrange in opposite directions two pieces of dividing plates are one Group, is provided with 2 groups～5 groups of dividing plates in shell.

As the further improvement of utility model, adjacent separator spacing be 4mm～ 60mm。

Advantageous Effects of the present utility model is: this utility model is by using labyrinth Formula structure realizes the filtration of dust, and the air-flow labyrinth type between dividing plate with dust is roundabout Process in passage, dust strikes and is blocked on dividing plate being deposited in housing, according to powder Dirt granular size and kind, can adjust the quantity of dividing plate, plate spacing, angle of inclination, Realize fully filtering, keep less gas-flow resistance, it is ensured that vacuum pump is normally transported simultaneously OK, dividing plate inverted draft one side surface is coated with fluorubber, increases the resistance of dust movement, Effectively dust can be blocked in shell wall, it is to avoid it flows out with air-flow, this practicality is new Type simple in construction, filters fully, it is possible to realize vacuum laser SLM printer working chamber Interior lasting dedusting, it is ensured that laser forming Product Precision, effectively extends the use of equipment Life-span.

Detailed description of the invention

Embodiment: a kind of vacuum laser SLM printer vacuum dust filter unit, including Shell, described shell end wall is formed with import 1, and another end wall of shell is formed There is outlet 2, intersect respectively on two relative sidewalls inside shell and be provided with some groups of dividing plates 3, form labyrinth type circuitous channel 4, this labyrinth type circuitous channel 4 between dividing plate 3 Two ends connect with import 1 and the outlet 2 of shell respectively.

During work, the import 1 of shell connects with vacuum laser SLM printer forming box, The outlet 2 of shell connects with vacuum pump, and vacuum laser SLM printer is become by vacuum pump Shape case evacuation all the time, gas and dust together enter filter from the import 1 of shell In, gas and dust flow in labyrinth type circuitous channel 4, and dust is at flow process In by the stop of dividing plate 3, settle down after it strikes dividing plate 3, so, Through the stop of multiple tracks dividing plate 3, the dust in air-flow is in all this stop is deposited to shell Portion, final clean air is discharged into vacuum pump from housing outlet 2, this filter Use labyrinth type filtration, it is achieved that tiny flow quantity, lower resistance filter, and both ensure Abundant filtration, turn avoid vacuum pump and damages, and achieve vacuum laser SLM In printer forming box, dust is discharged in time, it is ensured that laser forming precision.

Each dividing plate 3 described is obliquely installed towards outlet 2 direction of shell, Dou formula of inclining Dividing plate 3 has non-proliferation effect, it is to avoid pump oil vapour flows backwards and pollutes space, working chamber.

Described dividing plate 3 with and the vertical plane included angle of side wall of outer shell be 10 °～85 °.

Described dividing plate two-by-two 3 be arranged in parallel, it is ensured that air-flow smooth flow.

Described dividing plate 3 is fixed with extension fluorubber plate along the back side in air current flow direction, Increase dust movement resistance, make dust the most sufficiently deposit, it is to avoid its with Air-flow outflow filter.

Described shell includes first and second housing 5,6, first and second housing 5,6 energy Enough it is sealedly and fixedly connected, the first housing 5 medial wall is fixed with some rows and prolongs in the same direction The dividing plate 3 stretched, the second housing 6 medial wall is fixed with some rows and the first housing The dividing plate 3 that 5 medial wall upper spacers 3 are oppositely extending, the first housing 5 inboard partition 3 Just intersect one by one with the second housing 6 inboard partition 3, on the first housing 5 medial wall every Space is formed, inside the second housing 6 between plate 3 end and the second housing 6 medial wall Also space is formed between wall upper spacer 3 end and the first housing 5 medial wall, first, Also space is formed between dividing plate 3 adjacent on two housing 5,6 medial walls, split type Structure, it is simple to filter processing and manufacturing molding.

Described first and second housing 5,6 both ends form semi-circular cut-out respectively, the One, the semi-circular cut-out at two housing 5,6 both ends is just spliced into the import of filter 1 and outlet 2.

Described shell is column type structure or square chest type structure.

If arrange in opposite directions two pieces of dividing plates 3 are one group, in shell, it is provided with 2 groups～5 groups Dividing plate 3, this kind arranges good filtration effect, and little to gas-flow resistance.

Adjacent separator 3 spacing is 4mm～60mm, it is ensured that while filter effect, right Gas-flow resistance is little.
