Description
Technical field
It the utility model is related to a kind of gas-particulate filter import/export connection structure, and in particular to a kind of gas-particulate filter
With import/export integral connecting structure.
Background technology
Civil air defense constructions and installations is a kind of special hypogee for being used for wartime, having requirement of shelter, and the filtering for civil air defense constructions and installations is inhaled
Device is received, it is necessary to there is extremely strong filter effect, the air containing toxic gas, radioactive dust can be effectively filtered, in addition, bomb blast
After can produce enormous impact ripple, although when shock wave reaches gas-particulate filter, overbottom pressure has become very little, but still can be to filtering
Fine filter inside absorber causes to damage, and substantial amounts of dust also be easy to cause fine filter blocking, reduces its service life.
At present, gas-particulate filter inlet/outlet air diffuser connection structure, by two independent parts 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 is assembled with steel ring, carry out screwing bonding by spinning process.
The content of the invention
Goal of the invention：The purpose of this utility model is to overcome deficiency of the prior art, there is provided and one kind is integrally formed,
Use intensity is substantially increased, adds the tightness and product reliability of integral product, saves material cost, reduces energy wave
The people's air defense special filtering absorber inlet/outlet air diffuser integral connecting structure taken.
Technical solution：In order to solve the above-mentioned technical problem, a kind of people's air defense special filtering absorber described in the utility model
With inlet/outlet air diffuser integral connecting structure, it includes inlet/outlet air diffuser and steel ring, they are integrally formed, it is described into/
Outlet air diffuser includes taper inlet/outlet air diffusion shell and circular ring shape connecting portion, in the taper inlet/outlet air diffusion shell and circular ring shape
The junction of connecting portion is equipped with entry/exit air port, and the steel ring is structure of right angle tyoe, and the taper inlet/outlet air diffusion shell includes expanding
Joint face is dissipated, is equipped with reinforced convex surface on the diffusion joint face, the taper inlet/outlet air diffusion shell is connected from circular ring shape
Portion junction expands outwardly to and steel ring junction.
The inlet/outlet air diffuser and steel ring are all stainless steel.
Inlet/outlet air diffuser and steel ring the being integrated punch forming.
The opening inside diameter of the circular ring shape connecting portion is identical with the internal diameter size in entry/exit air port.
Four exterior angles of the steel ring are all fillet.
Beneficial effect：Compared with prior art, its remarkable advantage is the utility model：The utility model overall structure is set
Rationally, inlet/outlet air diffuser and steel ring being integrated punch forming, substantially increase overall use intensity, while add whole
The tightness and product reliability of body product, meet the requirement to product entirety air-tightness in filter end properties requirement,
Air leakage factor≤0.1%, solves former steel ring manufacturing process obtained by whole plate punch forming, among plate more than large area punching press
The problem of material wastes, saves production cost, sets reinforced convex surface, effectively improves the integral strength of diffusion joint face, meets reality
Border requirement.
Brief description of the drawings
Fig. 1 is the overlooking the structure diagram of the utility model；
Fig. 2 is the positive structure diagram of the utility model.
Embodiment
The utility model is further described 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 inlet/outlet air diffuser described in the utility model
Integral connecting 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 connecting portion 3, in the company of the taper inlet/outlet air diffusion shell 2 and circular ring shape connecting portion 3
Meet place and be 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, be equipped with reinforced convex surface 6 on the diffusion joint face 5, the taper inlet/outlet air diffusion shell 2 from circular ring shape connecting portion 3
Junction expands outwardly to and 1 junction of steel ring；The inlet/outlet air diffuser and steel ring 1 are all stainless steel；It is described into/
1 the being integrated punch forming of outlet air diffuser and steel ring；The opening inside diameter of the circular ring shape connecting portion 3 and entry/exit air port 4 it is interior
Footpath size is identical；Four exterior angles of the steel ring 1 are all fillet.It is reasonable that the utility model overall structure is set, inlet/outlet air diffusion
Device and steel ring being integrated punch forming, substantially increase overall use intensity, at the same add integral product tightness and
Product reliability, meets the requirement to product entirety air-tightness in filter end properties requirement, air leakage factor≤0.1%, solution
Former steel ring manufacturing process of having determined among plate the problem of the waste of large area punching press clout, is saved obtained by whole plate punch forming
Production cost, sets reinforced convex surface, effectively improves the integral strength of diffusion joint face, meets actual operation requirements.
The utility model provides a kind of thinking and method, and it is many to implement method and the approach of the technical solution, with
Only it is the preferred embodiment of the utility model described in upper, it is noted that for those skilled in the art,
