Abstract
A stacked and rolled type composite filter element comprises a composite filter screen and a filter pipe which is a porous metallic pipe. A seal cover is arranged at an upper end opening of the filter pipe, the composite filter screen is formed in a way that metallic screens in identical size and nonwoven cloth are stacked to be rolled into a cylinder around the filter pipe, and two ends and the middle of the cylinder are fastened by hoops. The metallic screens are flexible stainless steel screens, and the nonwoven cloth is made of polypropylene or polyethylene. The stacked and rolled type composite filter element is large in filtering flow volume, high in filtering precision, low in production cost, simple in manufacturing process and suitable for popularization and application.
Description
Technical field
The utility model relates to filter core, is specifically related to the filter core that the stack of a kind of wire netting and nonwoven is reeled.
Background technology
Filtering material commonly used has wire netting, nonwoven, gauze, nylon mesh, wool, filter paper, canvas etc.The selection of filter material is very important in practical application, be according to concentration, viscosity, the pH value of required treat liquid, and factors such as the concentration of operating temperature, filtering accuracy, solid impurity and particle diameter are taken all factors into consideration.Conventional filter material is easy blocking in filtration treatment, therefore use instead methods such as cleaning, more renew filter material always and keep filter efficiency, but except that the wire netting filter material, generally the anti-ten minutes that cleans is difficult after the filter material obstruction, and the frequent change filter material can improve production cost.
Wire netting and nonwoven are combined the technology that constitutes filter screen have advantages such as shock-resistant, good mechanical property.Application number is that the patent documentation of CN96231060.3 discloses a kind of special air conditioning for device room air cleaner; It is with wire netting and overlay on its surperficial chemical fibre filter cloth formation filter core; Application number is that the patent documentation of CN200920278416.4 discloses a kind of fiber-reactive charcoal composite screen, comprises that nonwoven layer, NACF layer, nonwoven layer and the wire netting of superimposed setting from top to bottom supports the layer that is shaped.Above patent documentation shows, the existing filter material that wire netting and nonwoven are combined is the individual layer stack, is used for gas filtration more, filters if use it for water treatment, and is then damaged by the water impact distortion easily.
The utility model content
To above-mentioned technical problem, the utility model provides a kind of composite filter element that the stack of wire netting and nonwoven is reeled and constituted, can flow impact resistant, and can take flushing apart after stopping up and utilize again.The utility model filtering traffic is big, and filtering accuracy is high, and production cost is low, and manufacturing process is simple, is suitable for applying.
The technical scheme of the utility model is following:
The folded formula composite filter element of volume comprises composite screen, chimney filter, and said chimney filter is covered with aperture, is provided with seal cover in the port of chimney filter; Said composite screen is the cylindrical body that measure-alike wire netting stack nonwoven is wound into around said chimney filter, and two ends and the middle part of said cylindrical body tighten with clip.
The width of said wire netting and nonwoven is 30 ~ 50cm, and length is 17 ~ 22m;
Said wire netting is soft stainless (steel) wire, and its footpath is 0.3 ~ 0.6mm, and its aperture is 120 ~ 180 orders;
Said nonwoven is a polypropylene non-woven fabric, and its thickness is 0.2 ~ 0.5mm, and the silk footpath is 3 ~ 5 Tekes, and the aperture is 150 ~ 200 μ m, and softening point is 120 ~ 150 ℃;
Perhaps said nonwoven is the polyethylene nonwoven, and its thickness is 0.2 ~ 0.5mm, and the silk footpath is 3 ~ 5 Tekes, and the aperture is 150 ~ 200 μ m, and softening point is 120 ~ 150 ℃;
The plate thickness of said chimney filter is 1.5 ~ 2mm, and diameter is 50 ~ 60mm, highly is 50 ~ 80cm;
The diameter of the aperture on the said chimney filter is 4 ~ 6mm.
The utility model beneficial technical effects is:
1, the wire netting and the non-woven fabric compounded stack of the folded formula composite filter element of this volume form the three-D space structure with space, and current can pass through from the three dimensions hole, so the rate of filtration is fast, and filtering accuracy is high, are not easy simultaneously to stop up.
2, the folded formula composite filter element of this volume increases along with handling Total Water, after the obstruction, can composite filter element be taken out from filtering container; Unclamp several roads clip on surface, laid out flat is on the level land, with the high pressure water washing that is added with cleaning agent; Roll up once more after cleaning finishes and gather into folds; Rechuck can use repeatedly, does not influence the rate of filtration and filtering accuracy.
Description of drawings
Fig. 1 is the front view of the folded formula composite filter element of this volume, among the figure: 1, composite screen; 2, chimney filter; 3, seal cover; 4, clip.
Fig. 2 is the vertical view of the folded formula composite filter element of this volume, among the figure: 1, composite screen; 3, seal cover.
The specific embodiment
Like Fig. 1, the folded formula composite filter element of preparation volume shown in 2, comprise composite screen 1, chimney filter 2, said chimney filter 2 is for being covered with the metal tube of aperture, is provided with seal cover 3 in the port of chimney filter 2; The cylindrical body that said composite screen 1 is wound into around chimney filter 2 for measure-alike wire netting stack nonwoven, two ends of said cylindrical body tighten with clip 4 with the middle part.
Wherein the width of wire netting and nonwoven is 40cm, and length is 20m; Wire netting is soft stainless (steel) wire, and its footpath is 0.5mm, and its aperture is 160 orders; Nonwoven is a polypropylene non-woven fabric, and its thickness is 0.3mm, and the silk footpath is 4 Tekes, and the aperture is 180 μ m, and softening point is 125 ℃; The plate thickness of chimney filter is 2mm, and diameter is 52mm, highly is 54cm; The diameter of the aperture on the chimney filter is 5mm.
