Abstract
The invention relates to an air filter. The air filter comprises a tubular housing, wherein the circumferential wall of the housing is tangentially provided with an air inlet; the housing is internally provided with two circular ring-shaped filter elements which are coaxially sleeved; both ends of the two filter elements are in sealing connection with the upper and the lower end of the housing respectively; the filter element with smaller diameter is internally provided with a cyclone separation device. The cyclone separation device is combined with a two-layer filter element filtering structure, and thus the filtering effect of the device is improved so as to purify air better; the sealing face of the filtering device and an end cover is enlarged, so that the air brake is prevented, and the filtering effect is improved.
Description
Technical field
The present invention relates to the filter technology field, especially a kind of air cleaner.
Background technology
Air cleaner uses comparatively general, air is filtered, thereby avoid entering cylinder with the air of particle, avoids the high equipment of cleanliness factor and environment are caused damage.Also there are a large amount of reports at home and abroad in air cleaner and use, as Chinese patent CN1139884A, a kind of cylindrical air filter and manufacture of casing thereof of radial seal have been introduced, this air cleaner includes a tubular metal housing with air intlet, plastic end cover and a filter element, air cleaning is had certain effect, yet because filter element is only one, be that air only can once be filtered, effect is bad, simultaneously because the sealing surface of filter element is few, there is the air short circuit phenomenon, be difficult to play a role in filtering.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of air cleaner, degree of filtration is high, and air purity is high.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: a kind of air cleaner, comprise tubular shell, described housing circle wall tangentially is provided with air inlet; In described housing, be provided with two coaxial sheathed circular filter cores of crossing, two described two ends of crossing filter core are tightly connected with the upper and lower side of described housing respectively; The described mistake in filter core of minor diameter is provided with cyclone separator.
Further, described cyclone separator consists of ring-shaped baffle and conical hopper, and the upper end of described ring baffle and described conical hopper is tightly connected; Described air inlet is communicated with the space between described ring baffle and described conical hopper.
Further, described filter core excessively is that cassette is connected with the two ends of described housing.
Compared with prior art, the present invention has the following advantages: adopt cyclone separator in conjunction with two-layer filter element filtering structure, improve the filter effect of this device, reach better and purify air; The sealing surface of filter element and end cap is increased, avoided the air short circuit, strengthen filter effect.
The accompanying drawing explanation
Fig. 1 is the structural representation that the present invention partly cuts open.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.
A kind of air cleaner as shown in Figure 1, comprise tubular shell, and described housing circle wall tangentially is provided with air inlet 1; In described housing, being provided with two coaxial sheathed circular filter cores 4 excessively and 5, two described two ends of crossing filter core is tightly connected with the upper and lower side of described housing respectively; The described mistake in filter core 4 of minor diameter is provided with cyclone separator 3.Described cyclone separator 3 consists of ring-shaped baffle and conical hopper, and the upper end of described ring baffle and described conical hopper is tightly connected; Described air inlet is communicated with the space between described ring baffle and described conical hopper.Described filter core excessively is that cassette is connected with the two ends of described housing.
Adopt inner filter core 4 and outer filter core 5 double medium filtrations, and double-deck filter core adopts cassette to be connected with the upper and lower side of housing, the air quality after assurance is filtered, play a protective role to follow-up environment or machinery equipment.
Air with dirt is entered by air inlet 1, and spiral is descending between ring-shaped baffle and conical hopper, the weight deposition, and cleaned air is up, as shown in fig. 1 air flow direction; After inner filter core 4 and 5 filtrations of outer filter core, airborne particle is filtered and is stayed again, and the air that purifies 2 outflows from gas outlet.
Claims (3)
1. an air cleaner, comprise tubular shell, it is characterized in that: described housing circle wall tangentially is provided with air inlet; In described housing, be provided with two coaxial sheathed circular filter cores of crossing, two described two ends of crossing filter core are tightly connected with the upper and lower side of described housing respectively; The described mistake in filter core of minor diameter is provided with cyclone separator.
2. air cleaner as claimed in claim 1, it is characterized in that: described cyclone separator consists of ring-shaped baffle and conical hopper, and the upper end of described ring baffle and described conical hopper is tightly connected; Described air inlet is communicated with the space between described ring baffle and described conical hopper.
3. it is characterized in that as claimed in claim 2: described filter core excessively is that cassette is connected with the two ends of described housing.
