Description
Technical field
The utility model is related to a kind of filter, more particularly to a kind of high accuracy multi-layer silk screen spherical filter.
Background technology
Space station in orbit during, when occurring catching fire or producing toxic gas in cabin, it is necessary to space station sealed compartment
Emergency pressure relief, emergency pressure relief feeder connection needs integrated two filters.It is big in the sealed compartment pressure leak process of space station in order to prevent
Block fifth wheel blocks filter, and filter uses spherical structure, filter equivalent latus rectum to be not less than 40mm, and filtering accuracy is not less than
20μm.Existing filter typically uses individual layer silk screen and skeleton welding structure form, and filtering accuracy reaches 20 μm of single-layer metal
Silk screen is general all very soft, it is difficult to process globulate, can only typically be processed into planar structure, in order to ensure filter intensity and
Rigidity, it is necessary to process baroque metallic framework.Therefore, existing filter exist complex structure, processing and manufacturing it is difficult,
The shortcomings of quality is big and is easily damaged short life.
The content of the invention
For the deficiencies in the prior art, problem to be solved in the utility model be to provide a kind of simple structure,
Filtering accuracy is high, strength and stiffness are good, convenient processing and manufacture, the spherical filter of long lifespan.
The technical scheme that the utility model solves the above problems is：A kind of spherical filter, including screen pack and flange, institute
Stating screen pack includes the casing play silk screen, filter layer silk screen and the protective layer silk screen that set gradually from inside to outside, three layers of silk screen welding
It is structure as a whole, and punching press globulate, screen pack and flange are integrated by being welded to connect.
Filter layer silk screen is clipped in the middle of protective layer silk screen and casing play silk screen, it is protected well, while also may be used
To ensure the high filtering precision and high stability of filter.Protective layer silk screen is played and protected in the outermost of filter layer silk screen
Not by the effect of impurity damage, casing play silk screen plays a part of support to filtering layer silk screen in the most beneath of screen pack, it is ensured that filtering
Net has preferable strength and stiffness.
The casing play silk screen, filter layer silk screen and protective layer silk screen are by the welding of vacuum electric welding resistance, screen pack and flange
By Welding.
The casing play silk screen and protective layer silk screen are coarse net, and filtering accuracy is 20 mesh, and filter layer silk screen is fine-structure mesh, filtering
Precision is 20um.Three layers of silk screen are made up of two-layer coarse net and one layer of fine-structure mesh, and three layers of silk screen are welded together by vacuum electric welding resistance,
Ensure not separated mutually during punch forming.
The casing play silk screen, filter layer silk screen and protective layer silk screen are stainless steel cloth.
The utility model has the advantages that：Woven wire as a result of three layers of different size forms one by vacuum-sintering
Body structure, it is ensured that the strength and stiffness of screen pack, can be with punching press globulate by special tooling, and processing and manufacturing is simple and convenient,
And strength and stiffness are good.The filter layer silk screen for constituting screen pack simultaneously is clipped in the middle of protective layer and casing play, it is obtained very well
Protection, while it is also ensured that the high filtering precision and high stability of filter.Protective layer silk screen screen pack outermost,
Play a part of to protect filter layer silk screen not by impurity damage, effectively extend the service life of filter.The utility model with
Traditional filter is compared without processing baroque metallic framework, so that filtration device structure is simple, light weight.
Brief description of the drawings
Fig. 1 is one structural representation of specific embodiment of the utility model；
Fig. 2 is the screen pack close-up schematic view of one specific embodiment of the utility model.
Reference：1- screen packs, 2- flanges, 11- casing play silk screens, 12- filter layer silk screens, 13- protective layer silk screens
Specific embodiment
Content of the present utility model is described in further detail below in conjunction with the drawings and specific embodiments：
Spherical filter as shown in Figure 1 and Figure 2, including screen pack 1 and flange 2, the screen pack 1 are included from inside to outside
Casing play silk screen 11, filter layer silk screen 12 and the protective layer silk screen 13 for setting gradually, three layers of silk screen are welded as a whole structure, and rush
It is pressed into spherical, screen pack 1 and flange 2 are integrated by being welded to connect.Filter layer silk screen 12 is clipped in protective layer silk screen 13 and skeleton
In the middle of layer silk screen 11, it is set to be protected well, while it is also ensured that the high filtering precision and high stability of filter.Protect
Sheath silk screen 13 plays a part of to protect filter layer silk screen 12 not by impurity damage, skeleton in the outermost of filter layer silk screen 12
Layer silk screen 11 plays a part of support in the most beneath of screen pack 1, it is ensured that screen pack 1 has preferable strength and stiffness.
The casing play silk screen 11, filter layer silk screen 12 and protective layer silk screen 13 are welded by vacuum electric welding resistance, screen pack 1
Pass through Welding with flange 2.
Three layers of silk screen are made up of two-layer coarse net and one layer of fine-structure mesh, and the casing play silk screen 11 and protective layer silk screen 13 are thick
Net, filtering accuracy is 20 mesh, and filter layer silk screen 12 is fine-structure mesh, and filtering accuracy is 20um.Three layers of silk screen are welded by vacuum electric welding resistance
It is connected together, it is ensured that do not separated mutually during punch forming.Simple shape can only be processed into compared to traditional individual layer silk screen
Filter, multi-layer silk screen of the present utility model can be with the complicated shape filter such as punching press globulate, without as traditional single-layer yarn
Web filter needs to process filter skeleton, and coarse net can substitute filter skeleton completely, and strength and stiffness are all preferable, filter
The efficiency of processing is significantly improved；Screen pack 1 uses spherical structure, it is ensured that the circulation area of filter and prevent bulk fifth wheel
Block filter.
The casing play silk screen 11, filter layer silk screen 12 and protective layer silk screen 13 are stainless steel cloth.
Filter equivalent latus rectum 40mm, 20 μm of filtering accuracy, outward appearance structure spherical in shape, with simple structure, filtering essence
The advantages of degree height, good strength and stiffness, light weight, convenient processing and manufacture, long lifespan, can be used as machineries such as valve, pump and blower fans
The inlet filter of equipment is used.
