Description

A kind of air filter assembly

Technical field

This utility model relates to a kind of air filter, specifically a kind of air filter assembly.

Background technology

Air filter is mainly used in the field such as pneumatic machinery, diesel machine, and effect is the air providing cleaning for these plant equipment, in case these plant equipment suck the probability increasing abrasion with the air of impurity particle and damaging at work.Traditional air filter connects air filter casing either directly through air inlet pipe, it is supply arrangement gas after in air filter casing, filter element filtering is set, the critical point having the disadvantage that air inlet pipe is the air inlet meeting huge discharge, blowing is needed to go out larger interior diameter, when internal diameter is bigger, its mouth of pipe decrease in strength, affects its service life；The multistage package assembly of air inlet pipe and the locked clip device that is connected by with air filter case, easy loose or dislocation under life-time service vibration；Air inlet pipe air inlet is directly filtered in air filter case, and inflow noise is big, and filter element is not easily changed.

Summary of the invention

For deficiency of the prior art, this utility model provides a kind of simple in construction, compact, takes into account air intake structure intensity, noise reduction, is connected firmly, and the further noise reduction of air filter case, good filtration effect, the convenient air filter assembly of filter element replacing.

The technical solution of the utility model is: a kind of air filter assembly, including air inlet pipe, air filter casing and filter element, air filter casing includes upper cover and lower chambers, described bottom chamber is provided with hush pipe, air inlet pipe is arranged on lower chambers outer wall and connects hush pipe, hush pipe offers multiple uniform bloop, hush pipe connection air filter pipe, described lower chambers outer wall is additionally provided with resonance box and the filter element chamber of locking can be opened, filter element is arranged at filter element intracavity, air filter pipe connection filter element chamber, described hush pipe or air filter pipe are provided with the high frequency waves long tube of more than and the low frequency wave long tube of more than, the high frequency waves long tube connection resonance box of more than one, the low frequency wave long tube of more than one does not stretch out lower chambers and external port is closed.

Further, described high frequency waves long tube connects on hush pipe and is located proximate to air inlet pipe end.

Further, described low frequency wave long tube closed outer end mouth supports or is fixed on the latticed reinforcement of bottom chamber.

Further, described air inlet pipe includes pipe in horn mouth outer tube and flat mouth, one end of horn mouth outer tube is horn mouth, the outer wall of the other end of horn mouth outer tube is provided with snap fit or inwall is provided with bayonet socket, in flat mouth, one end of pipe is flat mouth, in flat mouth, the outer wall of the other end of pipe is provided with snap fit or inwall is provided with bayonet socket, in the other end of horn mouth outer tube and flat mouth, the other end of pipe coordinates grafting clamping through bayonet socket and snap fit, in flat mouth, pipe is corrugated tube near the part of the other end, in flat mouth, the flat mouth in pipe one end coordinates bayonet socket or snap fit grafting lower chambers through its outer wall upper clamping hook or inwall upper latch notch.

Further, bell-mouthed interior oral cavity, described horn mouth outer tube one end is provided with the support column of more than one integrally blow.

Further, in described flat mouth, the interior oral cavity of the flat mouth in pipe one end is provided with the support column of more than one integrally blow.

Further, in described horn mouth outer tube and flat mouth, pipe grafting is by the key on its wall and keyway pairing, and in described flat mouth, pipe and lower chambers grafting are by the key on its wall and keyway pairing.

Further, described horn mouth outer tube is provided with the fixing seat of more than, and fixing seat supports connection horn mouth outer tube through forming the parallel brace rod of multiple tracks with horn mouth outer tube integrated injection molding.

Compared with prior art, the utility model has the advantages that:

1, air inlet pipe adopts pipe in horn mouth outer tube and flat mouth to be formed by connecting, the inserting mode of snap fit and bayonet socket, grafting is convenient, firm, fit key and keyway pairing, ensure that grafting is accurate, and bellows piece can be set at arbitrary pipeline section, taking into account air inlet noise reduction resonance satisfied different mounting location lower inlet duct corrugated tube simultaneously can meet fixing needs by mild distortion, it is to avoid the rigid awkward assembling of conventional gas introduction pipe solid structure is fixed；Meanwhile, integrated injection molding multiple tracks brace rod support connection fixing base in air inlet pipe, fixing seat is connected firmly in air inlet pipe, it is to avoid the fixing seat of tradition is connected the hidden danger easy to fall off existed with the sideline of air inlet pipe, it is ensured that fix safely, securely；

2, the support column of above integrally blow together is set in the interior oral cavity of horn mouth or flat mouth, supports the flat upper and lower inwall of the upper and lower inwall of horn mouth internal orifice or flat mouth, it is ensured that its bigbore mouth of pipe intensity, increase the service life.

3, after air inlet pipe accesses air filter casing, first the hush pipe noise reduction of band bloop, high frequency waves long tube is being connect on the hush pipe of air inlet pipe, the logical resonance box of high frequency waves long tube effectively eliminates high frequency noise, and hush pipe connects many low frequency wave long tubes, and low frequency wave long tube collar extension is closed and supports fixing with lower chambers, effectively eliminate low frequency noise, finally passing into the outer filter element chamber being connected on air filter tank wall by filter element filtering, after filtration, internal unit supply is used, filter element intracavity filter element replacing is convenient.
