Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of dust-filtering purification system for SLM device of the present invention, as shown in Figure 1, including passing sequentially through pipeline phase
Even and form the forming chamber 100 of closed loop, cyclone separator 200, two-stage HEPA Rose Box 300, blower 400；
Cyclone separator 200 is collected the bulky grain in dust, and excessive dust is avoided to reduce it through filtration core
Shelf life.
300 cabinet independent design of two-stage HEPA Rose Box, it can be ensured that when to filter process will not contaminated equipment other
Component guarantees equipment neat and tidy.
Machine 400 of giving a dinner for a visitor from afar for the flowing of air-flow provides power.
As shown in Fig. 2, two-stage HEPA Rose Box 300 includes the cabinet 1 of side opening, 1 upper bottom surface of cabinet, which is worn, is connected to air inlet
Pipe 2, one end that air inlet pipe 2 is located in cabinet 1 are sequentially connected the first bellows 4, shunt metal plate 5, is low precision filter 6, high-precision
Filter 7, escape pipe 8 are spent, escape pipe 8 passes through 1 bottom surface of cabinet and connects the second bellows 13, and air inlet pipe 2 is connected by pipeline
Cyclone separator 200, the second bellows 13 connect blower 400 by pipeline.
Shunting metal plate 5 is horn-like structure, and the one end for being open small connects the first bellows 4, and one end connection for being open big is low
Precision filter 6 shunts in metal plate 5 and the array hole metal plate that can be shunted is arranged close to the big one end that is open, guarantees with dust
Air-flow can scatter when entering two-stage filter, so that effectively being cut by air-flow when low precision filter 6, high-precision filter 7
Face is sufficiently large, effectively promotion filter effect, while also can avoid air-flow and being only concentrated through filter core center regional area, improves filter core
It can guarantee good filter effect while service life.
