Abstract

The utility model relates to an activated carbon filter, which comprises an outer filter frame, a filter member and sieves; wherein the sieves are arranged on both surfaces of the filter member; the filter member is fixed in the outer filter frame; and the activated carbon filter is characterized in that the upper and the lower layers of the filter member are non-woven fabrics, between which a layer of activated carbon granules are sandwiched. The utility model simplifies the fabrication technique and reduces the investment and the cost; the folding type enlarges the filtering area, the adsorption capacity is high, and resistance is low; since the activated carbon granules are sandwiched between the two layers of non-woven fabrics, dust can be prevented from falling off to cause secondary pollution; and since the structure of the filter is compact and reasonable, the mounting space can be saved.

Description

A kind of active carbon filter

Technical field

The utility model relates to the air cleaning unit of harmful substance in the filtering air, relates in particular to a kind of active carbon filter.

Background technology

At present, in central fan system,, improve air quality, can in ventilating system, install active carbon filter additional usually for removing airborne peculiar smell and pernicious gas.And existing active carbon filter is that 92221886.2 Chinese patent exists complex manufacturing technology as the patent No., and filter area is little, and dust comes off and causes secondary pollution problem, has hindered further promoting the use of of active carbon filter.

The utility model content

The utility model provides a kind of active carbon filter at the above-mentioned defective of prior art, to simplify filtration device structure, prevents from that dust from coming off to cause secondary pollution.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of active carbon filter comprises filter housing, filter core, screen cloth, and the two-sided screen cloth that covers of filter core is fixed in the filter housing, it is characterized in that: the upper and lower two-layer nonwoven that is of described filter core accompanies the layer of active carbon particle in the middle of the nonwoven.

Preferably, left and right two inboards of filter housing are brushed with white glue with vinyl, housing upper and lower two inboard pad NACFs.

Preferably, described filter core is for wavy through what fold.

Preferably, described screen cloth is the galvanized wire mesh of 6*6mm.

The advantage that compared with the prior art the utility model has: cover net folding and simplify manufacture craft, reduce investment cost, reduce cost; Collapsible increase filter area, adsorption capacity is big, and resistance is low; Two-layer nonwoven folder granular activated carbon can prevent that dust from coming off and cause secondary pollution; Structure of filter compactness, reasonable has been saved installing space.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is a filter core sectional view of the present utility model.

The specific embodiment

Below in conjunction with the specific embodiment the utility model is described in further detail.

Extremely shown in Figure 3 referring to Fig. 1, active carbon filter described in the utility model mainly contains the housing 1 of filter and is loaded on folding sandwich active carbon filter core 2 in the housing 1, filter core 2 covers 3 one on double side zinc coating wire netting when folding folding, in housing 1 the right and left inner side brush white glue with vinyl, housing is two inboard pad NACFs up and down, in case leak-stopping wind.Filter core 2 upper and lower two-layer be nonwoven 21, accompany layer of active carbon particles 22 in the middle of the nonwoven 21.Be installed in the housing 1 through being folded in behind the filter core 2 two-sided plating zinc-iron silk screens.

As preferred implementation of the present utility model, screen cloth adopts the galvanized wire mesh of 6*6mm.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.

Claims

1, a kind of active carbon filter comprises filter housing, filter core, screen cloth, and the two-sided screen cloth that covers of filter core is fixed in the filter housing, it is characterized in that: the upper and lower two-layer nonwoven that is of described filter core accompanies the layer of active carbon particle in the middle of the nonwoven.

2, active carbon filter according to claim 1 is characterized in that: left and right two inboards of filter housing are brushed with white glue with vinyl, housing upper and lower two inboard pad NACFs.
