Description

Seven apertures in the human head PVC milipore filter

Technical field

The utility model relates to a kind of seven apertures in the human head PVC milipore filter, mainly can be used for the water purified treatment.

Background technology

How in a tubular form the ultrafiltration body of existing seven apertures in the human head PVC milipore filter, the centre is provided with a hole (pore), and water passes tube wall from the outside, enters in the hole of ultrafiltration body, the ultrafiltration body that particulate contamination in the water and macromolecule contaminant are configured tube wall filters out, and realizes the purpose of purifying waste water thus.Owing to have only a hole in the pipe of this seven apertures in the human head PVC milipore filter, therefore the effective filtration area under the unit volume that forms is little, has restricted disposal ability.

The utility model content

For overcoming the above-mentioned defective of prior art, the utility model provides a kind of seven apertures in the human head PVC milipore filter, and the effective filtration area under this milipore filter unit volume is big, helps improving disposal ability.

The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of seven apertures in the human head PVC milipore filter, comprise ultrafiltration body in a tubular form, and be provided with a plurality of holes in the described ultrafiltration body.

The beneficial effects of the utility model are: owing to be provided with a plurality of holes in the ultrafiltration body of tubulose, therefore the effective filtration area that forms under same volume is big, for improving filter capacity, reducing the filter plant volume condition is provided.

The specific embodiment

Referring to Fig. 1, Fig. 3, Fig. 4 and Fig. 5, the invention provides a kind of seven apertures in the human head PVC milipore filter, the ultrafiltration body 10 of this seven apertures in the human head PVC milipore filter is provided with a plurality of holes 20 in a tubular form in the ultrafiltration body.Usually, the hole of elliptical aperture or other arbitrary shapes also can be arranged in these Kong Weiyuan holes or approximate hole, garden.

As shown in Figure 1, the quantity in the hole in the described ultrafiltration body can be 7, and one of them hole is positioned at central authorities, and other 6 holes evenly distribute along a circumference around the hole of central authorities.

As shown in Figure 3, the quantity in the hole in the described ultrafiltration body is 3, and described 3 holes evenly distribute along a circumference.

As shown in Figure 4, the quantity in the hole in the described ultrafiltration body is 4, and described 4 holes evenly distribute along a circumference.

As shown in Figure 5, the quantity in the hole in the described ultrafiltration body is 5, and described 5 holes evenly distribute along a circumference.

The quantity in the hole in the described ultrafiltration body also can adopt other quantity.

Referring to Fig. 2, can be divided into alternate

close filtering layer

12,13,14 and thin filtering layer 11 in the described ultrafiltration body, be provided with some thin cavitys in the described close filtering layer, be provided with some thick cavitys in the described thin filtering layer, thus when water passes close filtering layer, need more by the filtration entity on the ultrafiltration body, form effectively and filter; When passing the coarse filtration layer, can enter the thick cavity in the coarse filtration layer, enter the filtration entity of back by thick cavity, not only on the filtration entity in zone, ultrafiltration surface, form effectively thus and filter, on the filtration entity of ultrafiltration body inside, also form effectively and filter, increase effective filtration area greatly, also reduced the resistance of filtering bodies simultaneously.The shape of described various cavitys can be determined by preparation technology, can be the cavity of regular shape, but mostly usually are erose cavitys.The size of thin cavity and thick cavity can be set according to actual needs, different cavity parameters can be set in preparation technology, form two kinds of cavitys of thickness, perhaps in preparation process, form the cavity of different sizes naturally by preparation technology.So-called thin cavity and thick cavity are relative concepts, and the average-size that refers to a kind of cavity (thin cavity) is less than another kind of cavity (thick cavity).

Usually, the outer surface edge zone of described ultrafiltration body and the marginal surface zone in inner each hole are

close filtering layer

12,13, so not only convenient processing, and help in filtering bodies, carrying out the reasonable distribution of close filtering layer and thin filtering layer, increase effective filtration area to greatest extent.

Also be provided with the close filtering layer 14 of one deck between the close filtering layer of the close filtering layer of described ultrafiltration external surface fringe region and inner each hole surface fringe region, to improve effective filtration area.

Be equipped with between described each close filtering layer and dredge filtering layer 11, so that make the water that passes the close filtering layer of one deck enter next close filtering layer rapidly, reduce the resistance between each close filtering layer, and because these lower resistance are dredged the setting of filtering layer, water is all had on all directions of each close filtering layer comparatively uniformly distribute, to improve effective rate of utilization each close filtering layer.

The thickness of the close filtering layer of the close filtering layer of described ultrafiltration external surface fringe region and inner each hole surface fringe region is greater than the close thickness of filter bed between these marginal surface zones, so that form good balance between filter effect and resistance.

The present invention can adopt various suitable materials such as PVC to make, and adopts the PVC material to help reducing production costs.

Filter the internal microstructure of entity and the technology that the preparation method can adopt prior art and other any suitable among the present invention.
