Abstract

A composite microporous membrane hollow core filtering plate belongs to the technical field of liquid filtering, which is composed of double-layer microporous membrane hollow core slabs and is characterized in that an lining of the composite microporous membrane hollow core filtering plate is a fine filter layer, the microporous membrane pore diameter of the fine filter layer conforms to fine filter requirements, a preliminary filter layer is coated on the upper surface, the lower surface and the circumferential surface of the fine filter layer, the microporous membrane pore diameter of the preliminary filter layer is larger than that of the fine filter layer, the two layers have the same microporous direction, a central through hole which can be inserted with a flow guide pipe with a groove is inserted in the center of the filtering plate, and the central through hole is linked with tubular cavities of the fine filter layer by a plurality of pores. In filtration, fluid passes through micropores of the external preliminary filter layer and the micropores of the internal fine filter layer and flows in the central through hole, then the fluid is output by the flow guide pipe with a groove inserted in the center of the filtering plate, and a required filter fluid sample is obtained. The filtering plate can complete preliminary filter and fine filter in one time, which has dual purposes, can not only reduce troubles of filter operation but also lower filter cost.

Description

Composite micro porous film hollow filter

[technical field]

The utility model relates to a kind of microporous barrier hollow filter that is used for liquid beverage filters such as drinks, is a kind of composite micro porous film hollow filter specifically.

[background technology]

As everyone knows, the liquid beverages such as drinks that each enterprise produces all will filter before packing, be used for the equipment that this class I liquid I beverage filters at present, generally be to adopt the micro-pore-film filtration machine of forming by polylith microporous barrier hollow filter, existing used its micropore size of microporous barrier hollow filter of micro-pore-film filtration machine has only single specification usually, for the degree of purity that makes liquid beverages such as drinks meets or exceeds state specified standards, many enterprises often adopt the microporous barrier hollow filter of different size to comprise the multiple times of filtration of coarse filtration and smart filter, the microporous barrier hollow filter that this specification is single, not only to increase the filtration cost of enterprise, but also to increase operational trouble, prolong filtration time.

[summary of the invention]

For overcoming the single trouble of bringing of filter specification of existing microporous barrier hollow filter, the utility model provides a kind of composite micro porous film hollow filter, so that the liquid beverage that is assembled into by the such filter of polylith filters the task that function is finished coarse filtration and smart filter simultaneously, reduce troublesome poeration, reach the machine purposes of doing more.

For solving its technical problem, the technical solution adopted in the present invention is: design a kind of two-layer composite micro porous film hollow filter that has, its feature is: the nexine of 1. described double-deck microporous barrier hollow filter is a filter bed of essence, filter bed of essence up and down and circumferential surface be provided with the coarse filtration layer, the microporous barrier micropore size of this coarse filtration layer is greater than the aperture of filter bed of essence microporous barrier micropore.2. described composite micro porous film hollow filter is a round sheet sheet material, be provided with at the center of this filter and can intert the through hole of band groove mozzle, the inner hole wall of this through hole is provided with a plurality of apertures, and these apertures connect with the cavity of the filter bed of essence microporous barrier hollow that links to each other respectively.3. the coarse filtration layer of composite micro porous film hollow filter parcel smart filtering layer, the micro-hole of coarse filtration layer is consistent with the orientation of filter bed of essence micro-hole, and the microporous barrier hollow cavity of the fine holes of the thick micropore of coarse filtration layer and filter bed of essence and filter bed of essence, the aperture on the filter central through hole wall and the filter centre bore company of passing through mutually.

The microporous barrier hollow filter that the utility model and existing specification are single has been compared following two significant advantages: the one, and the utility model is established coarse filtration layer and filter bed of essence, make filtrate earlier through coarse filtration, automatically flow to filter bed of essence again and carry out secondary smart filter, twice filtration once finished, reduce operation and gone up trouble, improved the efficient of filtering; The 2nd, because of the smart filter of coarse filtration is integrated, make task of wanting two filters to finish, just can finish with the novel filter of this reality for one, dual-use can be saved the filter plant cost for enterprise.

[description of drawings]

The present invention is further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation cutaway view of the present utility model.

Fig. 2 is a structural representation vertical view of the present utility model.

Among the figure: 1 coarse filtration layer; 2 filter bed of essence; 3 cavitys; 4 central through holes.

[specific embodiment]

With reference to accompanying drawing: select for use to conform with smart filter and require the microporous membrane material in aperture to make the filter bed of essence 2 of round sheet, mid portion at filter bed of essence 2 is provided with cavity 3, be provided with coarse filtration layer 1 the upper and lower of filter bed of essence and circumference outer end face, the micropore size of this coarse filtration layer is greater than the aperture of filter bed of essence micropore, and coarse filtration layer micropore and the filter bed of essence micropore company of passing through mutually; Form the composite microporous hollow filter of the utility model by filter bed of essence 2 and coarse filtration layer 1, be processed with axial central through hole 4 at the center of this filter, through hole 4 is provided with small through hole with the cavity 3 corresponding hole walls of filter bed of essence 2, and this aperture makes the cavity 3 of filter bed of essence connect with central through hole 4.Be interspersed with the mozzle of band groove during work in the filter central through hole, liquid to be filtered around the filter through the gross porosity of coarse filtration layer 1, again through the pore of filter bed of essence 2 and the aperture on cavity and the central through hole wall, flow into central through hole 4, the mozzle that last filtrate wearing long is inserted in the central through hole flows out, and becomes qualified filtrate finished product.
