Abstract

The utility model relates to a membrane composite filtering cloth. A filter membrane (1) and a lining cloth (2) are composited into two layers or multi-layers composite material through adhesive joint; the utility model can be used for the dust removal for various atmosphere and the purification for liquid whose dust particle is below 1 micron. The utility model has the advantages of high efficiency of filtering and long service life.

Description

The film composite filtering cloth

The utility model relates to a kind of material that is used for industrial production and sphere of life dedusting, filtration, specifically is a kind of film composite filtering cloth.

Present industrial filter cloth is difficult to filtering to diameter at the dust granules below 5 microns.In the purified treatment of domestic water, adopt PE filter core or special film usually, the former low price effect is bad, though latter's effect is pretty good, but costs an arm and a leg, and the life-span is short.So known technology still can not effectively overcome the weak point of above-mentioned existence.

The purpose of this utility model is to provide a kind of novel filter cloth, and its adopts the MULTILAYER COMPOSITE between material, makes the filter efficiency height and cost is lower.

For achieving the above object, the utility model adopts following technical scheme:

By filter membrane (1) and lining cloth (2) by the bonding compound film composite filtering cloth integral body that becomes two layers or multilayer.Its complex form is:

Filter membrane (1)+lining cloth (2), or: filter membrane (1)+lining cloth (2)+filter membrane (1); Or: lining cloth (2)+filter membrane (1)+lining cloth (2), or: filter membrane (1)+lining cloth (2)+filter membrane (1)+lining cloth (2); Or: filter membrane (1)+lining cloth (2)+filter membrane (1)+lining cloth (2)+filter membrane (1)+lining cloth (2); Or: filter membrane (1)+lining cloth (2)+filter membrane (1)+lining cloth (2)+filter membrane (1) or: filter membrane (1)+lining cloth (2)+lining cloth (2)+filter membrane (1)+lining cloth (2)

Accompanying drawing of the present utility model and drawing are described as follows:

Fig. 1 is the cutaway view of two tunic composite filtering cloths;

Fig. 2 is the cutaway view of trilamellar membrane composite filtering cloth;

Fig. 3 is the cutaway view of trilamellar membrane composite filtering cloth;

Fig. 4 is the cutaway view of four tunic composite filtering cloths;

Fig. 5 is the cutaway view of six tunic composite filtering cloths;

Fig. 6 is the cutaway view of five tunic composite filtering cloths;

Fig. 7 is the cutaway view of five tunic composite filtering cloths;

Among the figure: 1. filter membrane, 2. lining cloth.

Now in conjunction with the accompanying drawings the best is implemented to be described in down:

Main material 1, i.e. polyvinyl fluoride filter membrane (1) by different base materials, adopts Method for bonding, the air-flow pressure sintering, different complex method such as meltblown is with base material, and promptly lining cloth (2) is compounded on the main material.Concrete composite bed can be combined into two tunic composite filtering cloths with main material (1) and base material (2), and as Fig. 1, also available main material (1) is combined into the trilamellar membrane composite filtering cloth at base material (2) two faces respectively, as Fig. 2; Also available base material 2 is combined into the trilamellar membrane composite filtering cloth at main material 1 two faces respectively, as Fig. 3; Also the method for available Fig. 1 is made four tunic composite filtering cloths, as Fig. 4; The method of also available Fig. 2, Fig. 3 is made six tunic composite filtering cloths, as Fig. 5; Also available Fig. 1 adds the method that Fig. 2 or Fig. 1 add Fig. 3 and makes five tunic composite filtering cloths, and as Fig. 6, also available different base material 2 is made the film composite filtering cloth of the different numbers of plies.

The utility model film composite filtering cloth, but can two layers also multilayer, also can two kinds or multiple material Carry out the composite membrane-forming composite filtering cloth, therefore have following significant practical advantage: 1. can be widely used in grit at all kinds of atmosphere dedustings below 1 micron, the needs of fluid purification; 2. because the teflon membrane filter smooth surface is more convenient for equipment, the recoil of equipment filtering layer, prolong The service life of filter cloth.
