Abstract

The utility model discloses a rolled membrane screen structure, which consists of a plurality of transverse ribs and a plurality of longitudinal ribs. The transverse ribs are sandwiched among the longitudinal ribs. When a screen is matched with a membrane element, the transverse ribs do not contact with a membrane surface but contact with the longitudinal ribs only, directions of the longitudinal rids are consistent with a feeding direction, the screen has no dead angles after feed liquid enters a runner. Further, since the transverse ribs do not contact with the membrane surface, turbulence effect of the feed liquid is promoted while membrane filter area is expanded, and membrane filter efficiency is increased while settling of pollution is avoided. Accordingly, an existing thick water screen structure is modified, the transverse ribs of the screen do not contact with the membrane surface, and two shortcomings of the existing structure are overcome.

Description

Rolled film filter structure

Technical field

The relevant a kind of membrane separation technique of the utility model is meant a kind of rolled film filter structure especially.

Background technology

Cooperate shown in Fig. 1,2,3, no matter the dense water filter of existing domestic and international rolled film element is rhombus filter or rectangle filter, and its horizontal bar 1 all is partial to one side of longitudinal rib 2, and promptly horizontal bar 1 contacts with face 3.There are following 2 big defectives in the runner that forms between filter that is made of horizontal bar 1 and longitudinal rib 2 and the face 3 Kuai, a state in the Zhou Dynasty when work like this:

1,, thereby but reduced the reality usable floor area of membrane component because horizontal bar 1 tightly contacts with face 3, and the face 3 that causes being covered by horizontal bar 1 can't contact with feed liquid.

2, owing to be formed with angle between feedstock direction and the horizontal bar 1, horizontal bar 1 and face 3 position contacting form the dead angle, make that pollutant A is easy to deposit in this position, dead angle or block, and cause irrecoverable contact scar, also reduce the membrane component usable area simultaneously.

The utility model content

The purpose of this utility model provides a kind of rolled film filter structure, and it can improve the usable floor area of membrane component, avoids the generation at dead angle in the runner, and then prevents the deposition of pollutant.

For achieving the above object, solution of the present utility model is:

A kind of rolled film filter structure is made of a plurality of horizontal bars and a plurality of longitudinal rib, and wherein: each horizontal bar is to be folded between each longitudinal rib.

After adopting such scheme, because each horizontal bar in the filter structure is between each longitudinal rib, when then filter cooperates with membrane component, horizontal bar can not contact with face, and only have longitudinal rib to contact with face, but longitudinal rib is consistent with feedstock direction, and then feed liquid is after entering runner, filter can not produce the dead angle, horizontal bar does not contact with face simultaneously, plays when promoting the feed liquid turbulent flow, has increased the area of membrane filtration, promptly improved the efficient of membrane filtration, prevented the deposition of pollutant again, therefore, filter architecture advances of the present utility model existing dense water filter structure, the filter horizontal bar is not contacted with face, avoid two big defectives of existing structure.

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

Fig. 3 is the amplification work schematic diagram of Fig. 2;

Fig. 4 is the front view of the utility model filter structure;

Fig. 5 is that the B-B of Fig. 4 is to cutaway view;

The specific embodiment

A kind of rolled film element filter structure extremely shown in Figure 6 as Fig. 4, that the utility model discloses, it is made of with a plurality of longitudinal ribs 5 a plurality of horizontal bars 4 equally, and key is: each horizontal bar 4 is to be folded between longitudinal rib 5.

When then filter cooperated with membrane component, horizontal bar 3 can not contact with face 6, and only has longitudinal rib 5 to contact with face 6, but longitudinal rib 6 is consistent with feedstock direction, then feed liquid is after entering runner, and filter can not produce the dead angle, and the solid content in the feed liquid should not be stuck in and cause obstruction on the filter.Horizontal bar 4 does not contact with face 6 simultaneously, plays when promoting the feed liquid turbulent flow, has increased the area of membrane filtration, has promptly improved the efficient of membrane filtration, under the same situation of other conditions, can increase the actual available membrane area of 10-20%.

Therefore, filter architecture advances of the present utility model existing dense water filter structure, filter horizontal bar 4 is not contacted with face 6, avoid two big defectives of existing structure.

Claims (1)

1. a rolled film filter structure is made of a plurality of horizontal bars and a plurality of longitudinal rib, it is characterized in that: each horizontal bar is to be folded between each longitudinal rib.
