Abstract

The utility model discloses a point-rest type filter without a baffle plate, relating to a filter for filtering various fluid media. The stripe-shaped separators of the existing filter are changed into point-shaped separators with small area. A plurality of upward or downward point-shaped bulges are regularly produced as the separators when filtering materials are produced, or the point-shaped separators made of plastic are arranged out of the plate-shaped filtering materials when the plate-shaped filtering materials are folded, and two layers of filtering material are supported and fixed by adhesive. The utility model can keep minimum contact area among the filtering materials, effective filtering area is enlarged, and the filtering materials are supported and stressed reasonably. The point-rest type filter without a baffle plate has easy fabrication, material saving and low cost, and the point-rest type filter without a baffle plate can be used for filtering various fluids.

Description

Point-rest type filter without division plate

The utility model relates to a kind of filter that filters various fluid media (medium)s, does not have baffle filter especially for the point-rest type of filtered air in the air-conditioning system.

When filtering various fluid media (medium), for appearance and size and the raising filter efficiency that reduces filter, filtrate in the filter is always made through repeatedly folding, keep certain distance as the passage that is filtered medium between the folding filtrate in order to make, must be separated out between each metafiltration material, be that what is called has baffle filter, its volume weight is all big; After develop into separators such as paper slips, plastic ties, alleviated the part weight and volume, still have complex process, the shortcoming of waste material.Little fold-type of the external invention of the eighties does not have baffle filter have been cancelled and has added separator, and filtrate itself has the bar shaped projection as separator, though reduced weight and volume, but still have following shortcoming:

1, filtrate itself is concavo-convex alternate, and the bar shaped projection links to each other when filtrate is folding, because of filtrate simultaneously is stressed, makes filtrate itself be easy to generate distortion, increases resistance.

2, in order to prevent filtrate distortion, the bar shaped partitioned portion of filtrate itself must take bigger area and be used for separation support between the two-layer filtrate, has reduced the effective filtration area of filtrate.

3, filtrate itself must possess bigger deflection, and further reduction resistance is restricted.

The purpose of this utility model provides a kind of improved no baffle filter, avoids the filtrate distortion, reduces the effective filtration area that separator accounts for to greatest extent, thereby improves effective filtration area.

Solution of the present utility model is: change present filter into area very little point-like separator by the bar shaped separator, it is stressed rationally to reduce rest distance and rest, thereby reach the increase effective filtration area, avoid the filtrate distortion, reduction is to the requirement of filtrate deflection, reduce the resistance of filter, economical with materials.

Below in conjunction with specific embodiment technical characterictic of the present utility model is described in further detail.

Fig. 1 does not have the part expanded view of baffle filter filtrate (1) for point-rest type, when producing filtrate, just produce some alternate up and down point-like projectioies as separator (2) regularly, but it is then protruding to same one side in both sides, broken line place, stain is represented to lower convexity among Fig. 1, and white point is represented to raise up.These some expression filtrates (1) among the figure are being rolled over behind the A-A alignment, the corresponding position of point-like projection when before the B-B alignment, rolling over, point-like projection on two filtrates (1) the rest filtrate (1) that contacts makes to form certain spacing between each sheet of filtrate (1), so that filter medium passes through.

Figure 2 shows that another kind of embodiment, when plate shaped filtrate (1) is folding, add point-like separator (2), separator (2) can be made of light materials such as plastics, the mode that sticks with glue is fixed two-layer filtrate (1) rest, paster more than the A-A line and above below the B-B line being, paster below between two lines, when behind the A-A alignment, rolling over, when before the B-B alignment, rolling over, point-like separator (2) rest filtrate (1) is all arranged between per two filtrates (1), make it separately, be filtered the interval that medium passes through thereby form.

In the filtrate production process, the gluing rule of the making of point-like projection or point-like separator (2) also can have other arrangement mode, or it is evenly arranged evenly not have the standard of strict rule.

The utility model makes and keeps minimum contact area between each sheet filtrate (1), thereby improved effective filtration area, again because separator (2) is the very little point-like sheet of area, thereby economical with materials, and make easily, cost is lower, and is easy to utilize, not only can be used for the filtration of gases such as air, and can be used for the filtration of multiple liquid.

Claims (3)

1, a kind of point-rest type does not have baffle filter, and it has filtrate (1) and separates the separator (2) of filtrate (1), it is characterized in that separator (2) is the very little point-like of area.

2, filter according to claim 1 is characterized in that producing some point-like projectioies up or down as separator (2) on filtrate (1).

3, filter according to claim 1, when it is characterized in that filtrate (1) is folding by adding point-like separator (2) rest.
