Description
Technical field
The present invention relates to a kind of gas-particulate filter import/export connection structures, and in particular to a kind of gas-particulate filter with into/
Export integral connecting structure.
Background technique
Civil air defense constructions and installations be it is a kind of for wartime, have the special hypogee of requirement of shelter, the filtering for civil air defense constructions and installations is inhaled
Device is received, extremely strong filter effect is needed, can effectively filter the air containing toxic gas, radioactive dust, in addition, bomb blast
After can generate enormous impact wave, although shock wave reach gas-particulate filter, overbottom pressure has become very little, but still can be to filtering
Fine filter inside absorber damages, and a large amount of dust also be easy to cause fine filter to block, and reduces its service life.
Currently, gas-particulate filter inlet/outlet air diffuser connection structure, by two independent components of inlet/outlet air diffuser and steel ring
Composition, and the manufacturing process of steel ring, obtained by whole plate punch forming, large area punching press clout wastes among plate, inlet/outlet air
By sealing glue when diffuser and steel ring assemble, carry out screwing bonding by spinning process.
Summary of the invention
Goal of the invention: purpose of the invention is to overcome the shortcomings in the prior art, provides a kind of integrated molding, significantly
Use intensity is improved, the tightness and product reliability of integral product are increased, material cost is saved, reduces energy waste
People's air defense special filtering absorber inlet/outlet air diffuser integral connecting structure.
Technical solution: in order to solve the above-mentioned technical problem, a kind of people's air defense special filtering absorber of the present invention with into/
Outlet air diffuser integral connecting structure, it includes inlet/outlet air diffuser and steel ring, they are integrally formed, and the inlet/outlet air expands
Scattered device includes taper inlet/outlet air diffusion shell and circular ring shape interconnecting piece, in the taper inlet/outlet air diffusion shell and circular ring shape interconnecting piece
Junction be equipped with entry/exit air port, the steel ring be structure of right angle tyoe, the taper inlet/outlet air diffusion shell include diffusion connection
Face, is equipped with reinforced convex surface on the diffusion joint face, and the taper inlet/outlet air diffusion shell is connect from circular ring shape interconnecting piece
Place expands outwardly to and steel ring junction.
The inlet/outlet air diffuser and steel ring are all stainless steel material.
The inlet/outlet air diffuser and steel ring are integrated punch forming.
The opening inside diameter of the circular ring shape interconnecting piece is identical with the inner diameter size in entry/exit air port.
Four exterior angles of the steel ring are all fillet.
The utility model has the advantages that compared with prior art, the present invention its remarkable advantage is: overall structure setting of the present invention is reasonable, into/
Outlet air diffuser and steel ring are integrated punch forming, substantially increase whole use intensity, while increasing integral product
Tightness and product reliability meet the requirement in filter end properties requirement to product entirety air-tightness, air leakage factor
≤ 0.1%, solve former steel ring manufacturing process obtained by whole plate punch forming, large area punching press clout waste among plate
Problem saves production cost, reinforced convex surface is arranged, and effectively improves the integral strength of diffusion joint face, meets actual use and want
It asks.
Detailed description of the invention
Fig. 1 is overlooking structure diagram of the invention；
Fig. 2 is positive structure diagram of the invention.
Specific embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of people's air defense special filtering absorber of the present invention inlet/outlet air diffuser one
Formula connection structure, it includes inlet/outlet air diffuser and steel ring 1, they are integrally formed, and the inlet/outlet air diffuser includes taper
Inlet/outlet air diffusion shell 2 and circular ring shape interconnecting piece 3, in the junction of the taper inlet/outlet air diffusion shell 2 and circular ring shape interconnecting piece 3
Equipped with entry/exit air port 4, the steel ring is structure of right angle tyoe, and the taper inlet/outlet air diffusion shell 2 includes diffusion joint face 5,
The diffusion joint face 5 is equipped with reinforced convex surface 6, and the taper inlet/outlet air diffusion shell 2 is connect from circular ring shape interconnecting piece 3
Place expands outwardly to and 1 junction of steel ring；The inlet/outlet air diffuser and steel ring 1 are all stainless steel material；The inlet/outlet air
Diffuser and steel ring 1 are integrated punch forming；The opening inside diameter of the circular ring shape interconnecting piece 3 and the internal diameter in entry/exit air port 4 are big
It is small identical；Four exterior angles of the steel ring 1 are all fillet.Overall structure setting of the present invention is reasonable, inlet/outlet air diffuser and steel ring
For integrated punch forming, substantially increase whole use intensity, at the same increase integral product tightness and product it is reliable
Property, meet the requirement in filter end properties requirement to product entirety air-tightness, air leakage factor≤0.1%, before solving
Steel ring manufacturing process among plate the problem of the waste of large area punching press clout, saves production cost obtained by whole plate punch forming,
Reinforced convex surface is set, effectively improves the integral strength of diffusion joint face, meets actual operation requirements.
The present invention provides a kind of thinking and methods, and there are many method and the approach for implementing the technical solution, the above institute
Stating is only the preferred embodiment of the present invention, it is noted that for those skilled in the art, is not being departed from
