Abstract
The invention provides a spherical filter with a simple structure, a high filtration precision, good strength and rigidity, light weight, manufacturing convenience and a long service life. The spherical filter comprises a filter screen and a flange. The filter screen orderly comprises a skeleton layer silk screen, a filter layer silk screen and a protective layer silk screen from inside to outside. The three layers of silk screens are welded together to form a spherical structure. The filter screen and flange are welded together to form an integral body. The spherical filter solves the problem that the existing filter has a complex structure, high manufacturing difficulty and large mass, is easy to damage and has a short service life. The filter can be used as an inlet filter for mechanical equipment such as a valve, a pump and a fan.
Description
Technical field
The present invention relates 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, need space station sealed compartment
Emergency pressure relief, emergency pressure relief feeder connection need 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 adopts spherical structure, filter equivalent latus rectum to be not less than 40mm, and filtering accuracy is not less than
20μm.Existing filter typically adopts monolayer silk screen and skeleton welding structure form, filtering accuracy to reach 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 by this invention is to provide a kind of simple structure, filtration
High precision, strength and stiffness are good, the spherical filter of convenient processing and manufacture, life-span length.
Technical proposal that the invention solves the above-mentioned problems is：A kind of spherical filter, including drainage screen and flange, the mistake
Filter screen includes casing play silk screen, filter layer silk screen and the protective layer silk screen for setting gradually from inside to outside, and three layers of silk screen are welded as one
Body structure, and punching press globulate, drainage screen 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 so as to 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 was 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 in the most beneath of drainage screen to filtering layer silk screen, it is ensured that filter
Net has preferable strength and stiffness.
The casing play silk screen, filter layer silk screen and protective layer silk screen are through the welding of vacuum electric welding resistance, drainage screen 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, is filtered
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,
Mutually do not separate during ensureing punch forming.
The casing play silk screen, filter layer silk screen and protective layer silk screen are stainless steel cloth.
It is an advantage of the invention that：As a result of three layers of different size metal gauze by vacuum-sintering integral knot
Structure, it is ensured that the strength and stiffness of drainage screen, can be simple and convenient with punching press globulate, processing and manufacturing by special tooling, and by force
Degree and good rigidity.The filter layer silk screen for constituting drainage screen simultaneously is clipped in the middle of protective layer and casing play so as to protected well
Shield, while it is also ensured that the high filtering precision and high stability of filter.Protective layer silk screen is played in the outermost of drainage screen
Protect filter layer silk screen not by the effect of impurity damage, effectively extend the service life of filter.It is of the invention with traditional mistake
Filter is compared without processing baroque metallic framework, so that filtration device structure is simple, light weight.
Description of the drawings

Fig. 2 is the drainage screen close-up schematic view of a specific embodiment of the invention.
Reference：1- drainage screens, 2- flanges, 11- casing play silk screens, 12- filter layer silk screens, 13- protective layer silk screens
Specific embodiment
Present disclosure 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 drainage screen 1 and flange 2, the drainage screen 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, drainage screen 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 so as to protected well, while it is also ensured that the high filtering precision and high stability of filter.Protect
Outermost of the sheath silk screen 13 in filter layer silk screen 12, plays a part of to protect filter layer silk screen 12 not by impurity damage, skeleton
Layer silk screen 11 plays a part of support in the most beneath of drainage screen 1, it is ensured that drainage screen 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 through vacuum electric welding resistance, drainage screen 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 are 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 mutually do not separate during punch forming.Simple shape can only be processed into compared to traditional monolayer silk screen
Filter, the multi-layer silk screen of the present invention can be with the complicated shape filter such as punching press globulate, without as traditional monolayer silk screen mistake
Filter needs to process filter skeleton, and coarse net can substitute filter skeleton completely, and strength and stiffness are all preferable, filter processing
Efficiency significantly improve；Drainage screen 1 adopts 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, filter essence
The advantages of degree height, good strength and stiffness, light weight, convenient processing and manufacture, life-span length, can be used as machineries such as valve, pump and blower fans
The inlet filter of equipment is used.
