Description

A kind of air filter

Technical field

The present invention relates to a kind of air filter.

Background technology

Air filter (AirCleaner) is mainly used in the field such as pneumatic machinery, diesel machine, 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.The key component of air filter is filter element and casing, and wherein filter element is main filtration fraction, carries the filtration work of gas, and casing is must external structure to be protected for filter element offer.The job requirement of air filter is to undertake the work of high efficiency air-filtering, does not increase too much resistance for air flowing, and can long time continuous working.

Existing air filter, owing to air is under impacting with high pressure, it is impossible to filtered fully in filter element, air out cannot meet higher pure requirement, and existing air filtering device structure is complicated, at high temperature, it is easy to leakage, breaks down.

Summary of the invention

The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of simple in construction, filter air filter more fully.

The purpose of the present invention implements by the following technical programs:

A kind of air filter, is made up of filtering lid, filtering cup, filter, air inlet and gas outlet, and described filtering lid seals with filtering cup and combines；Described filtering is covered with filter and gas outlet, and the top of described filtering cup is provided with air inlet；

The cylindrical structure of described filter, and it extend in filtering cup, seal with filtering cup and combine；

Described filtering cup is in the pyramidal structure with spherical bottom, and described air inlet is downward-sloping setting, and gas pours at the bottom of bottle；

Described air inlet place is provided with trapezoidal deflector；

The spherical bottom of described filtering cup fills out punching two-layer filler, and upper strata is one or both the mixing in activated carbon, zeolite, lower floor is soda lime；

Described filter is made up of the air buffer chamber of filter element Yu filter element upper strata, and described air buffer chamber connects with gas outlet, and described surge chamber is filled with the montmorillonite of loose structure.

Preferably, it is 45-60 degree angle at the bottom of the wall of cup of described filtering cup and cup.With 45 degree of angles for optimum selection.

Preferably, journey 45-85 degree angle at the bottom of described air inlet and filtering cup cup.With 60 degree of angles for optimum selection.

Preferably, the spherical bottom upper strata filler of described filtering cup is activated carbon: the mass ratio of zeolite is the mixture of 2:1.

Air is entered by air inlet, bottom the entrance filtering cup of deflector, is flowed out by gas outlet after entering air buffer chamber then through the air after filter element filtering.

Beneficial effects of the present invention:

Air filter provided by the invention, the setting of the Ball-type packing layer at the bottom of cup, the air air poured from air inlet had the effect as lower attraction, it is to avoid air, directly into filter element, can make the filled absorption that the moisture of filtration is instant simultaneously.And, filtering cup conical design trapezoidal deflector collaborative under, the air entanglement forming uniform pressure at the bottom of cup can be enabled air to and crossing around air filtration, and the structural design of surge chamber, the flow velocity making from filter element air out is cushioned, so by the pressure effect at filter element two ends, make the air in filter element uniformly boundless and indistinct wherein, purified fully.
