Pleated filter wall

The innovation relates to a folded filter wall with deformations pressed into the individual ribs.

It is known to enlarge a filter area by placing it in folds. If the folding is carried out very tightly , there is a risk that the individual folds of the fold will lie against one another, as a result of which the efficiency of the folded filter wall is significantly reduced.

According to the invention, this disadvantage is to be prevented are made by introducing suitable deformations in the hips of the fold.

The details of the innovation are shown in the accompanying drawing.

Figure 1 shows a folded filter wall from the front with 3 possibilities of the innovation according to the deformation of the hips of the folded filter wall

Figure 2 shows the section through Figure 1 along the section line AB seen from above

Figure 5 shows the section through a known, tightly folded filter wall, which is laid in a known manner in the shape of an arc of a circle after folding.

As shown in Figure 3, it is known to fold a filter surface 1 - preferably made of fabric, perforated sheet metal, felt or paper - so that individual lips 2 are formed · Passages 3 must remain between the individual ribs so that the substance to be filtered can pass can. The narrower the fold, the narrower the passage 3 *, especially when the folded filter wall according to FIG To ensure, according to Figure 1 and 2, according to the innovation, additional deformations are pressed into the ribs.

The folded strip according to FIGS. 1 and 2 is improved on the left, for example, by Extensions 5 are pressed between the ribs 2.

The example in the middle of FIGS. 1 and 2 shows impressions 6 in the ribs 2 the adjacent ribs kept at a distance and the remaining openings 7 allow unimpeded Passage of the substance to be filtered. The right embodiment of Figure 1 and 2 shows transverse folds 8 directed to the right. These transverse folds are designed so that they are on the left Form a widened passage 9 and rest on the right on the left leg 1o of the adjacent rib.

Auen through, this deformation of the clans becomes one Prevents contact with the rib legs 1o over the entire length of the rib and improves the flow. In terms of this innovation, deformations of the ribs and rib legs can also be formed that have other shapes but are able to have sufficient passage between to keep two adjacent ribs open.

The listed deformations of the ribs or rib thighs can, if necessary should also be introduced on both sides of the folded pilter wall.

Claims (1)

PA673 680 * 10/22/62 C " -4-protection requirements 1 «) Folded filter wall made of fabric, perforated plate., Mushroom, filter paper or the like, thereby characterized in that the ribs or rib legs in regular, or irregular Distances deformed in this way by enlargements, impressions, cross folds, bulges, etc. that the rib leg pieces that are not deformed on this? / iron that between the deformations, cannot come together, 2 #) G-folded filter wall according to claim 1, characterized characterized in that enlarged by widening two adjacent rib legs Passages remain that allow an Iluß of the substance to be filtered, whether probably the adjoining rib leg pieces that were not deformed in this way can lie against each other. 3.) G-folded 3? Filter wall according to claim 1 and 2, characterized in that the ■ deformations either only on the front or only on the back, or equally on the front and back the filter wall are located.
