Abstract
The utility model relates to a composite filter element for metal fiber sintered felt, which comprises metal fiber sintered felt and a filter membrane formed by a metallic membrane, an organic membrane or a ceramic membrane on the metal fiber sintered felt. When the filter element is in use, both the filter capacity and the filter element strength are optimized, and the pressure is hardly lost while the filter element mechanical strength is guaranteed, so that the circulation is not affected; the metallic membrane, the organic membrane or the ceramic membrane sintered with a porous substrate has the function of separating solid particles, and the separation precision can reach the unit of submicron; since the membrane is thinner, the blockage can be avoided, the filter effect is better, and the precision is higher; and in reverse washing regeneration, filter cake impurity liquid can easily drop off from the surface, so that the service life of the filter element is prolonged.
Description
Technical field
The utility model relates to a kind of fluid filter element that is used to filter various materials and separating micro-diameter particles, is specially a kind of metallic fiber sintered felt composite filtering element.
Background technology
At present, the filtration fraction of employed metallic fiber sintered felt filter element all is a symmetrical structure in the industrial production, the filtering accuracy minimum can only be accomplished 1 micron, and circulation is extremely low when adopting the high accuracy filter element, filter material thickness is thicker, and enter wherein as particulate and stop up easily, and easy to clean not after stopping up, thereby influence filter effect and filter efficiency, shorten the service life of filter element.
Summary of the invention
The technical problem that the utility model solves provides a kind of filtering accuracy height, reduces the accumulation obstruction, improves filter efficiency, prolongs the filter element metallic fiber sintered felt composite filtering element in service life.
The utility model adopts following technical scheme:
The utility model comprises metallic fiber sintered felt and is arranged on the filter membrane that the one deck on the metallic fiber sintered felt is made of metal film, organic film or ceramic membrane.
The utility model metallic fiber sintered felt is cylindric, on the cylindrical metal fiber sintering felt serving inner surface or outer surface be provided with the filter membrane that one deck is made of metal film, organic film or ceramic membrane.
The beneficial effects of the utility model are: it is metallic fiber sintered felt as base material that the utility model is selected gross porosity footpath material for use, filter membrane in substrate surface spraying or the metallic film in the fine aperture of sintering one deck, organic film or ceramic membrane formation, thereby optimize filter capacity and two indexs of filer element strength, when guaranteeing the filter core mechanical strength, produce pressure loss hardly, thereby guarantee that its circulation is also unaffected; Function of separating solid particles, then by bearing with porous substrate sintering metallic film, organic film or ceramic membrane together, separation accuracy can reach submicron order, because this layer film thinner thickness, thus be difficult for blocking, and also filter effect is better, precision is higher, in the time of backwash and regeneration, filter cake impurity liquid comes off from its surface easily, thereby has prolonged the service life of filter element.

The specific embodiment
As shown in Figure 1, the utility model filter element is made base material by rough grade tabular metallic fiber sintered felt 1, surface or lower surface spraying thereon or the ultra-thin metal film of sintering last layer, and ceramic membrane or organic film are as filter membrane 2.
As shown in Figure 2, the utility model filter element is made base material by rough grade tubular metallic fiber sintered felt 1, spraying or the ultra-thin filter membrane 2 of sintering last layer on barrel outer surface or the inner surface, filter membrane 2 is a metal film, ceramic membrane or organic film. present embodiment is at outer surface spraying or sintering filter membrane 2.
The utility model is optimized filter capacity and filer element strength, when guaranteeing the filter core mechanical strength, produces pressure loss hardly, thereby guarantees that its circulation is also unaffected; Function of separating solid particles, then by bearing with porous substrate sintering metallic film, organic film or ceramic membrane together, separation accuracy can reach submicron order, because this layer film thinner thickness, thus be difficult for blocking, and also filter effect is better, precision is higher, in the time of backwash and regeneration, filter cake impurity liquid comes off from its surface easily, thereby has prolonged the service life of filter element.
The utility model metallic fiber sintered felt water penetration characteristic test (shown in the accompanying drawing 3):
Method of testing standard: ISO 4022
Specimen shape: disk, thickness 3mm
Filter area: 50.26cm2/
Water temperature: 20 ℃
The utility model metallic fiber sintered felt air permeability characteristic test (shown in the accompanying drawing 4):
Method of testing standard: ISO 4022
Specimen shape: disk, thickness 3mm
Filter area: 50.26cm2/
Air themperature: 20 ℃
Air pressure: 101.3Kpa
As shown in accompanying drawing 3,4:
1-1 is the metallic fiber sintered felt filter element curve of 3.0 microns of traditional filtering accuracies among the figure;
1-2 is the metallic fiber sintered felt filter element curve of 5.0 microns of traditional filtering accuracies among the figure;
1-3 is the metallic fiber sintered felt filter element curve of 10.0 microns of traditional filtering accuracies among the figure;
2-1 is the metallic fiber sintered felt composite filtering element curve of 0.5 micron of filtering accuracy among the figure;
2-2 is the metallic fiber sintered felt composite filtering element curve of 1.0 microns of filtering accuracies among the figure;
