Abstract

The utility model relates to a dustless type highly-efficient filtering screen which comprises a frame body and a filtering layer. The frame body is formed by combining two L-shaped supporting frames in a detachable way and form a hollow space, and the two L-shaped supporting frames form a groove upwards, the groove surrounds the hollow space, the filtering layer is provided with a plurality of filter paper layers, plastic material is adhered around the filter paper layers for fixation, the filtering layer is arranged in the hollow space in order to ensure the plastic material to extend into the groove, thus the groove grips the plastic material to fix the filtering layer, hereby, the air passes through the filtering layer, and then dust micro particles in the air can be filtered for providing pure air for indoor use, and when the filtering layer is required to be replaced, the two L-shaped supporting frames are only required to be disassembled and then the filtering layer can be taken out for replacement, thus the cost for repair and maintenance is low, and the dustless type highly-efficient filtering screen has environmental protection concept.

Description

Dustless formula high efficiency filter screen

Technical field

The utility model relates to a kind of dust free room equipment, relates in particular to the air filter screen structure of a kind of used in dustless room in the filtering dust particle.

Background technology

Dust free room is semiconductor industry, opto-electronics and the indispensable processing site of precision optical machinery processing industry, it can avoid airborne dust fall to influence process rate, for keeping the cleanliness factor of dust free room, must allow and remain malleation in the dust free room, to avoid dust particle to waft in the dust free room, therefore must be by behind the air filter screen filtering dust in air particulate, so that pure air is sent in the dust free room only.

See also shown in Figure 1, known air filter screen, it forms by the fixing a plurality of filter paper layer 2 of framework 1 clipping, can allow air form pure air via the filtration of these a plurality of filter paper layer 2, use for dust free room, these a plurality of filter paper layer 2 are after permanent the use, and it can reduce gas permeability because of the accumulation dust, thereby must be changed, to avoid the excessive or forfeiture dust removing effects of windage, known air filter screen, because framework 1 is fixing non-removable structure, thereby as changing this a plurality of filter paper layer 2, then must change together with framework 1, that is it must change whole air filter screen, thereby causes its replacement cost high, and the waste resource.

The utility model content

Therefore, main purpose of the present utility model is to provide a kind of filter structure of replaceable filter paper layer, to reduce its maintenance cost.

Via as can be known above, for achieving the above object, the utility model is a kind of dustless formula high efficiency filter screen, it comprises framework and filter course, wherein this framework is combined removably by two L type supports, and formation hollow space, and these two L type supports form groove inwardly, this groove is around this hollow space, and this filter course has a plurality of filter paper layer, binded by the plastics material and fix around these a plurality of filter paper layer, and this filter course is located in this hollow space, and allow this plastics material stretch in this groove, to fix this filter course by this plastics material of this groove clipping.

In view of the above, when the utility model was changed this a plurality of filter paper layer when needs, as long as these two L type supports are taken apart, promptly replaceable these a plurality of filter paper layer, and do not need all to change were compared knownly, and the utility model can reduce maintenance cost, satisfies user's demand.

The specific embodiment

For feature of the present utility model, purpose and effect are had more deep understanding and approval, now enumerate explanation of preferred embodiment and conjunction with figs. as back:

Shown in Fig. 2, Fig. 3-1 and Fig. 3-2, the utility model is a kind of dustless formula high efficiency filter screen, it comprises a framework 10 and a filter course 20, wherein this framework 10 is combined removably by two L type supports 11, and form a hollow space 12, can utilize at least one screw 30 mutual screw locks together as these two L type supports 11, and these two L type supports 11 form a groove 13 inwardly, this groove 13 is provided with posterior limiting 14, this elastic layer 14 can be made for rubber, and this groove 13 is around this hollow space 12.

This filter course 20 has a plurality of filter paper layer 21, binded by a plastics material 22 around these a plurality of filter paper layer 21 and fix, and this filter course 20 is located in this hollow space 12, and allow this plastics material 22 stretch in this groove 13, to fix this filter course 20 by this this plastics material 22 of groove 13 clippings, and this elastic layer 14 can contact for this plastics material 22, stability and air-tightness during with the increase clipping.

As mentioned above, two L type supports 11 of the present utility model are dismountable, so the filter course put of its inside 20 as when needing to change a plurality of filter paper layer 21, as long as these two L type supports 11 of dismounting can be changed easily, thereby can satisfy user's demand.
