Abstract
The utility model discloses an air filter. The air filter comprises a cylinder extending in the front and back direction. A rear end cover is arranged at the rear end of the cylinder. A filter element extending in the front and back direction is arranged in the cylinder. An annular air inlet cavity is formed in the cylinder and on the outer side of the filter element in the circumferential direction. An air inlet which extends in the circumferential direction around the filter element or is evenly distributed is formed in the rear end cover. The air inlet is correspondingly communicated with the annular air inlet cavity. Rotational flow blades used for guiding air to form rotational flow are arranged in the annular air inlet cavity and/or the air inlet. When air enters the annular air inlet cavity through the air inlet, air directly flows to the rotational flow blades without turning, and therefore the influences on the flow speed of air are eliminated, centrifugal force generated by subsequent rotational flow is ensured, and the processing effect of the rotational flow blades on large-grained dust in air is ensured.
Description
Technical field
The utility model relates to a kind of air-strainer.
Background technique
Air-strainer is for filtering air; to avoid airborne dust impurity to enter the next gas unit of using as in motor; general air-strainer mainly comprises housing and is arranged on the filter core in the inner chamber of housing; filter core is main filtration fraction; bearing the work of filtering gas, and housing is mainly used in providing necessary outer protection for filter core.
In the Chinese utility model patent specification that is CN200946541Y at notice of authorization number, a kind of eddy flow dry-type air cleaner is disclosed, filter cleaner comprises housing and filter core, week in filter core in housing is furnished with annular inlet chamber laterally, filter core middle part has middle outlet chamber, one end of housing is provided with the suction port, the other end that are communicated with air-inlet cavity and is provided with the air outlet being communicated with outlet chamber, and suction port and air outlet are all arranged on the neutral position place of housing respective end.When work, air to be filtered enters air-inlet cavity by suction port, after filter element filtering, is being drained by air outlet through outlet chamber.For protection filter core; between housing and filter core, be provided with around filter core circumferentially uniform for guiding air to form the swirl vane of eddy flow; swirl vane is located on wind scooper; in the time that flowing through swirl vane, the air of device to be filtered forms eddy flow; under the effect of centrifugal force; the dust that in air, particle is larger is thrown in inner walls, and drains through the dust outlet geometry being communicated with air-inlet cavity, and relatively clean air is filtered it by filter core again.
But the suction port in above-mentioned filter cleaner is arranged on the neutral position place of housing one end; and swirl vane must be around filter core circumferential arrangement in filter core outside; this is staggeredly arranged suction port and swirl vane; the air to be filtered that enters air-inlet cavity through suction port must turn after curved and just can flow on swirl vane; air can reduce flow velocity in turning process; and then affect the centrifugal force that follow-up eddy flow produces, affect the treatment effect of swirl vane to large particle dust in air.
Model utility content
The purpose of this utility model is to provide a kind of air-strainer, just can flow to solve the technical problem that swirl vane causes air velocity to reduce in prior art from suction port the air to be filtered entering must turn round.
For achieving the above object, the technological scheme of air-strainer provided by the utility model is: air-strainer, comprise the cylindrical shell extending along fore-and-aft direction, cylinder back-end is provided with rear end cover, in cylindrical shell, be provided with the filter core extending along fore-and-aft direction, in described cylindrical shell, be furnished with laterally annular inlet chamber in filter core week, on described rear end cover, offer around filter core and circumferentially extend or uniform suction port, suction port is corresponding with described annular inlet chamber to communicate, and is furnished with for guiding air to form the swirl vane of eddy flow in described annular inlet chamber and/or described suction port.
The described swirl vane and the rear end cover that are arranged in suction port are wholely set.
The corresponding sealing of front end of described cylindrical shell is fixedly inserted with front cover, filter core has middle outlet chamber, on described front cover, offer the air outlet being communicated with outlet chamber, described annular inlet chamber extends to described front cover place, on front cover or described cylindrical shell, be provided be communicated with described annular inlet chamber for discharging the Ash valves of dust.
Usefulness of the present utility model is: the suction port on the rear end cover of air-strainer provided by the utility model is around circumferentially extension or uniform of filter core; and suction port is corresponding identical with annular inlet chamber; suction port is just just to the swirl vane in annular inlet chamber and/or suction port; when air is in the time that suction port enters in annular inlet chamber; air will directly flow on swirl vane; do not need to turn round; and then eliminate the impact on air velocity; guarantee the centrifugal force that follow-up eddy flow produces, guarantee the treatment effect of swirl vane to large particle dust in air.
Further, swirl vane one is connected on rear end cover, like this, is convenient to simplify the overall structure of filter cleaner, improve installation efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of embodiment's of air-strainer provided by the utility model structural representation;
Fig. 2 is the right elevation of air-strainer shown in Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, a kind of embodiment of air-strainer, air-strainer in this embodiment comprises housing, housing comprises along fore-and-aft direction extends and two ends are the cylindrical shell 3 of hatch frame and peg graft with the corresponding fixing seal of cylindrical shell 3 both ends open front cover 1, rear end cover 6, between front cover 1 and cylindrical shell 3, be provided with front seal ring 2, rear end cover 6 and cylindrical shell 3 are fixed together by the clamp button of the spring 7 around circumferential arrangement, and after being provided with between rear end cover 6 and cylindrical shell 3 seal ring 5.The filter core 4 extending along fore-and-aft direction is installed in housing, in cylindrical shell, within 4 weeks, be furnished with laterally annular inlet chamber 10 in filter core, annular inlet chamber 10 extends to forward front cover 1 from rear end cover 6, outlet chamber 12 in the middle of being provided with at filter core 4 middle parts, on front cover 1, be provided with the air outlet 13 being communicated with middle outlet chamber 12, and on rear end cover 6, offer around circumferentially uniform suction port 11 of filter core, suction port 11 is corresponding with annular inlet chamber 10 to communicate.When use, the air of device to be filtered is entered in annular inlet chamber 10 by suction port 11, after filter core 4 filters, drains from air outlet 13 through outlet chamber 12.
