Description

Air filter

Technical field

The utility model relates to a kind of air filters, particularly relate to a kind of air filter for fresh air system.

Background technique

Fresh air system is the power-saving technology for communicating operator and being widely used, and general fresh air system all includes main equipment and control Two major parts of device, wherein main equipment be fresh air system air inlet and filtering capital equipment, critical component in addition to blower with It is exactly outside filter.Traditional fresh air system filter is generally using the planar structure filter for being similar to filter net type, largely Result of practical application show this filter there are serious dust blockage problem, even if dust also can with after the short period Strainer screen pore is blocked, intake is caused to substantially reduce.Since this drawback exists, so that this planar structure filters Device needs are regularly maintained, including clean or replace, to affect the using effect of fresh air system.

Currently, filtration device structure relatively new type in industry is in addition, bristle arrangements filter (Chinese Patent No. No. 201080047243.0) and ripple dust suction chip air filter (Chinese Patent No. 201410401567.X), both are new Type filter is used for fresh air system, although having preferable maintenance-free performance, the production installation of filter is more complicated, to mistake For the clipping room of the internal part of filter away from more demanding, production efficiency is lower, in actual production and life, using very wideless It is general.

Summary of the invention

The purpose of this utility model is to provide a kind of air filters, and pick-up performance is good, overcome plate filter Be easy blocking the problem of, substantially prolong the maintenance period of filter, at the same again have simple production process, high production efficiency, The advantages such as low to installation requirement.

To achieve the goals above, the utility model provides a kind of air filter, including air pipeline and filter core, described Filter core is set between the air inlet and air outlet of air pipeline, and the filter core is covered with the cross section of entire air pipeline, described Filter core is made of multiple dust adsorbents being stacked in a cartridge support frame, the dust adsorbent stack when between exist between Gap.

Further, the rough outer diameter of dust adsorbent is 2mm -20mm.

Further, the dust adsorbent is the sphere with certain surface roughness.

Further, the dust adsorbent is the irregular sphere that surface has recess or protrusion.The dust adsorbent Depression in the surface or projection length are 1-5mm.

Further, the multiple dust adsorbent is placed in hollow out accommodating cavity with 3-30 for one group.The hollow out is held Setting the rough outer diameter of chamber is 10-50mm.

Further, the area in gap is 1mm between the dust adsorbent²—25mm²。

Further, on the air-flow direction of air pipeline, the outer diameter of the dust adsorbent is sequentially reduced.

Further, on the air-flow direction of air pipeline, the dust adsorbent that 2-3 layers of outer diameter are gradually reduced is set.

The attainable beneficial effect of the utility model institute is:

1, the utility model carries out air filtration using novel dust adsorbent, has broken existing flat screen structure Constraint, filtration device structure is simple, easily fabricated.

2, the dust adsorbent of the utility model carries out dust absorption using rough surface to dust, between dust adsorbent Gap ventilating air, filter effect is good, be not easy to plug, the maintenance of clean-up time extend.

Specific embodiment

The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art The utility model can be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.

As shown in Figure 1, the embodiments of the present invention one, the utility model air filter includes air pipeline and filter The flow direction of core, air is from bottom to top that filter core is made of multiple dust adsorbents 2 being stacked in a cartridge support frame 1, Cartridge support frame 1 can be a flase floor, as long as guaranteeing that dust adsorbent is not fallen out.Filter core is set to air pipeline Between air inlet and air outlet, in the present embodiment, the dust adsorbent 2 is plastic sphere of uniform size, baton round body surface Face is rough surface, sphere diameter 10mm, and there are gaps between random each adsorbent of heap poststack.According to the big of air filter Small, the area in gap is 1mm between dust adsorbent²—25mm².In addition it is also possible to which multiple plastic spheres are placed in a hollow out In accommodating cavity 3, multiple hollow out accommodating cavities 3 are placed in cartridge support frame 1, as shown in Figure 2.

Refering to Fig. 3, another embodiment of the utility model, general structure is the same as example 1, and difference is this implementation Dust adsorbent is that surface has the sphere being uniformly recessed in example, and recess length is 1-5mm.Such as it can be similar golf Surface, this surface is more advantageous to absorption dust.

Refering to Fig. 4, the utility model embodiment three, dust adsorbent described in the present embodiment can such as divide three-layer set, On air inlet wind direction, the outer diameter of dust adsorbent is sequentially reduced, respectively 10mm, 5mm, 2mm, to reach the filtering effect of layering Fruit.

The dust adsorbent of the utility model is not limited to above structure, can also be cobblestone shape, and surface has column The sphere of shape protrusion, in short, can adsorbing dust and can stack to form any solid in gap and can constitute at random The dust adsorbent of the utility model.

Embodiment described above is only preferred embodiments for fully illustrating the utility model, the utility model Protection scope it is without being limited thereto.Those skilled in the art made equivalent substitute or change on the basis of the utility model It changes, both is within the protection scope of the present invention.The protection scope of the utility model is subject to claims.
