Description
Technical field
The present invention relates to a kind of air filter, is a kind of air filter assembly specifically.
Background technology
Air filter is mainly used in the field such as pneumatic machinery, diesel machine, and effect is for these plant equipment provide clean air, in case these plant equipment suck the probability increasing abrasion and damage with the air of impurity particle at work.Traditional air filter is directly communicated with air filter casing by air inlet pipe, be supply arrangement gas after in air filter casing, filter element filtering is set, have the following disadvantages: the critical point of air inlet pipe is the air inlet meeting huge discharge, blowing is needed to go out comparatively large diameter, when internal diameter is larger, its mouth of pipe intensity declines, and affects its service life; The multistage package assembly of air inlet pipe and adopt locked clip device with the connection of air filter case, the lower easy loose or dislocation of Long-Time Service vibration; Air inlet pipe air inlet is directly filtered in air filter case, and inflow noise is large, and filter core is not easily changed.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of structure simple, compact, take into account air intake structure intensity, noise reduction, be connected firmly, and the further noise reduction of air filter case, good filtration effect, filter element replacing is air filter assembly easily.
Technical scheme of the present invention is: a kind of air filter assembly, comprise air inlet pipe, air filter casing and filter core, air filter casing comprises upper cover and lower chambers, described bottom chamber is provided with hush pipe, air inlet pipe is arranged on lower chambers outer wall and is communicated with hush pipe, hush pipe offers multiple uniform bloop, hush pipe is communicated with air filter pipe, described lower chambers outer wall is also provided with resonance box and the filter core chamber that locking can be opened, filter core is arranged in filter core chamber, air filter pipe is communicated with filter core 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 of more than one is communicated with resonance box, 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 is communicated with position near air inlet pipe end on hush pipe.
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 comprises 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 bellows 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 matched by the key on its wall and keyway.
Further, described horn mouth outer tube is provided with the holder of more than, and holder is through forming the parallel brace rod support and connection horn mouth outer tube of multiple tracks with horn mouth outer tube integrated injection molding.
Compared with prior art, advantage of the present invention is:
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, guarantee grafting is accurate, and at arbitrary pipeline section, can bellows piece be set, take into account air inlet noise reduction resonance and meet different occasion lower inlet duct bellows of installing simultaneously and can meet fixing needs by mild distortion, avoid the rigid awkward of conventional gas introduction pipe solid structure to be mounted with; Meanwhile, integrated injection molding multiple tracks brace rod support and connection holder in air inlet pipe, holder is connected firmly in air inlet pipe, avoids traditional holder to be connected the hidden danger that easily comes off existed with the sideline of air inlet pipe, guarantees fixing safe, firm;
2, in horn mouth or flat mouth, oral cavity arranges the support column of above integrally blow together, supports the flat upper and lower inwall of the upper and lower inwall of horn mouth internal orifice or flat mouth, guarantees its bigbore mouth of pipe intensity, increase the service life.
3, after air inlet pipe access air filter casing, first the hush pipe noise reduction of band bloop, hush pipe near air inlet pipe connects high frequency waves long tube, high frequency waves long tube leads to resonance box 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 supported fixing with lower chambers, effective elimination low frequency noise, finally pass into and outer be connected on filter core chamber on air filter tank wall by filter element filtering, use internal unit air feed after filtration, filter core chamber inner filter core is changed convenient.
