Abstract
The utility model discloses a large -scale ventilation corridor airstrainer relates to air filter technical field, including frame, apron and filter media, the frame is long square frame structure, and the frame bottom is equipped with the grid of ventilating, the apron lower surface is equipped with the grid of ventilating, and hinge and frame attach are passed through to apron one end, and the other end is through detaining position device and frame attach, the filter media is folded many times and is continuous U-shaped, and the filter media is placed between frame and apron. The utility model discloses novel structure, reasonable in design, convenient to use, filter media fold many times and are continuous U-shaped, have increased the area of contact of filter media with the air, and the filter effect is better, the frame is connected with the apron is active, conveniently unpicks and washes, the emergence of having stopped ventilation corridor incident.
Description
Technical field
The utility model relates to air filter technical field, particularly relates to a kind of large-scale air filter screen for ventilation corridor.
Background technology
As everyone knows, the air filter on ventilation gallery is its important part.In the conventional technology, airstrainer is all the structure of plane formula, but with all the other working environments unlike, air mass flow in ventilation gallery is large, also relatively high to the requirement of airstrainer, the structure of plane formula and air contact surfaces amass little, and the effect of filtration is poor; In addition, large-scale ventilation gallery filter screen is easily dirty, and traditional airstrainer is integral type structure, inconvenience cleaning, and when the dust in filter screen is too much, blower fan running resistance is comparatively large, linkage section pressure may be caused to raise, cause security incident.
Summary of the invention
The utility model object is to provide a kind of large-scale air filter screen for ventilation corridor, can not only increase the contact area of filter material and air, can also be convenient for dismounting and washing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of large-scale air filter screen for ventilation corridor, relates to air filter technical field, comprises framework, cover plate and filter material; Described framework is rectangle frame structure, and base of frame is provided with air grid; Described cover plate lower surface is provided with air grid, and cover plate one end is connected with framework by hinge, and the other end is connected with framework by fastening device; Described filter material is repeatedly folding in continuous print " Qian " shape, and filter material is positioned between framework and cover plate.
Further, described framework and cover plate material are TPE plastic rubber, and both are all by particular manufacturing craft single injection-molded.
Further, described filter material material is non-woven fabrics.
Beneficial effect: compared with original technology, the large-scale air filter screen for ventilation corridor novel structure of one of the present utility model, reasonable in design, easy to use, filter material is repeatedly folding in continuous print " Qian " shape, and add the contact area of filter material and air, filter effect is better; Framework is connected with cover plate activity, convenient for dismounting and washing, has stopped the generation of ventilation gallery security incident.
Accompanying drawing explanation
Fig. 1 is overall construction drawing of the present utility model.
Fig. 2 is framework of the present utility model and covering plate structure schematic diagram.
Description of reference numerals: 1-framework, 2-cover plate, 3-filter material, 4-air grid, 5-hinge, 6-fastening device.
Detailed description of the invention
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the utility model further.
As depicted in figs. 1 and 2, a kind of large-scale air filter screen for ventilation corridor, relates to air filter technical field, comprises framework 1, cover plate 2 and filter material 3; Described framework 1 is rectangle frame structure, is provided with air grid 4 bottom framework 1; Described cover plate 2 lower surface is provided with air grid 4, and cover plate 2 one end is connected with framework 1 by hinge 5, and the other end is connected with framework 1 by fastening device 6; Described filter material folds in continuous print " Qian " shape for more than 3 time, and filter material 3 is positioned between framework 1 and cover plate 2.
Wherein, described framework 1 and cover plate 2 material are TPE plastic rubber, and both are all by particular manufacturing craft single injection-molded.
Wherein, described filter material 3 material is non-woven fabrics.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
