Technical field

The present invention relates to a kind of air filter, specifically a kind of buffering blast pipe and the air mistake that air inlet impact can be slowed down Filter.

Background technique

Air is the necessary condition of tellurian animals and plants existence, and animal breath, photosynthesis of plant all be unable to do without air； And for the high request high standard of air, being just pregnant with air filter in current production and living, in practice, in order to The filter effect of air is improved, often flow velocity is all quickly, rigid in exhausting for the filter screen of conventional rigid connection for the air of suction Into when, there are certain pressure difference in filtering, directly impact will cause filter screen damage.

Therefore, in order to overcome the problems, such as appeal, the present invention provides a kind of air for buffering blast pipe and can slowing down air inlet impact Filter.

Summary of the invention

The purpose of the present invention is to provide a kind of buffering blast pipe and the air filter entered the wind and impacted can be slowed down, to solve The problems mentioned above in the background art.

To achieve the above object, the invention provides the following technical scheme:

A kind of buffering blast pipe, including installing pipe and connecting tube, the described blast pipe further include screen pipe group；

The screen pipe group is removably mounted between the installing pipe and the connecting tube；

The impact of air inlet can be mitigated, the chimney filter group is made of outer tube and inner tube, and two are equipped between outer tube and inner tube A Buffer Unit being symmetric；

And said inner tube is equipped with bellows；

And air screen assemblies are installed inside said inner tube, and add on the outside of the air sieve that air screen assemblies are equipped with Equipped with buffer layer.

Specifically, when exhausting enters, the opposite stretching of bellows cooperates the elastic buffer and air of Buffer Unit Buffer layer is added on the outside of sieve, the impact of air can be buffered, nor affects on normal filtration, and then improve and use the longevity Life avoids directly impacting will cause filter screen damage.

Further embodiment of the present invention: the air screen assemblies are made of air sieve and outer fixed frame, and solid outside Determine frame in a ring, the limit of air sieve is inside outer fixed frame and buffer layer is arranged between air sieve and outer fixed frame.

The present invention further scheme: the buffer layer is gasket ring in elasticity.

The present invention further scheme: said inner tube is equipped with two section bellowss, and adds between two section bellowss Interior fixing pipe, air screen assemblies are mounted on inside interior fixing pipe, are connected with outboard tube on the outside of bellows；And said inner tube is worn It is inserted in outer tube, outer tube cooperation Buffer Unit offers cavity.

The present invention further scheme: Buffer Unit is stated equipped with limited block, limited block is arranged on inner pipe, and limits Block two sides are respectively fixed with an elastic component.

The present invention further scheme: the elastic component is made of spring and telescopic rod, and telescopic rod is interspersed in bullet Inside spring.

The present invention further scheme: the installing pipe and connecting tube are connected by inner connection tube and external pipe thread It connects, and inner connection tube is respectively arranged at outer tube both ends, and surface is equipped with screw thread.

The present invention further scheme: being equipped with the first fixed sleeving on the inside of the installing pipe, and the first fixed sleeving is logical It crosses screw thread to connect with inner connection tube, and the first fixed sleeving is by being provided with gasket, Yi Jian between screw thread and inner connection tube The first mounting flange is equipped on the outside of tubulature.

The present invention further scheme: being connect by the second fixed sleeving with inner connection tube on the inside of the connecting tube, and The second connecting flange is equipped on the outside of connecting tube.

It is a further object to provide the air filters that one kind can slow down air inlet impact, in the described filter Portion has installed the buffering blast pipe of above-mentioned record additional.

Compared with prior art, the beneficial effects of the present invention are:

When exhausting enters, the opposite stretching of bellows cooperates outside the elastic buffer and air sieve of Buffer Unit the present invention Side adds buffer layer, can buffer to the impact of air, nor affect on normal filtration, and then improve service life, avoid Directly impact will cause filter screen damage.
