Abstract

The utility model relates to a basket-chamber filter, which comprises a casing which is provided with an inlet and an outlet, wherein, a basket-chamber type filtering cylinder which is composed of a protective cover, a filtering screen cylinder, a supporting ring and a handle; a flange at the upper part of the basket-chamber type filtering cylinder is provided with a top cover; the flange and the top cover are tightened by screw bolts and nuts. The structure of the utility model has good tightness; high-pressure liquid in the casing can not leak out from a part between the top cover and the surface of the flange at the upper part; the utility model can be widely arranged on water pipelines and oil pipelines to filter impurities in the liquid.

Description

Basket chamber filter

The utility model relates to a kind of basket chamber filter that is installed on water delivery or the oil pipeline.

At present, be used in the basket chamber filter on water delivery or the oil pipeline, the form that adopts that cooperates between the oral area of its top cover and housing upper end is, above the oral area of housing upper end, the bearing cross beam that a center car has screw is set, is furnished with screw mandrel in the screw at this bearing cross beam center, the lower end and the top cover of screw mandrel offset, and realize closely cooperating between top cover and the housing upper end oral area by screwing this screw mandrel.In this fit system, only there is the center of top cover to accept top power, and is difficult to around the top cover to realize airtight with housing upper end oral area cause the highly pressurised liquid exosmose in the housing to take place often from screw mandrel.

The purpose of this utility model be to provide a kind of top cover can be airtight with housing upper end oral area, the basket chamber filter that can not exosmose of the highly pressurised liquid in the housing.

Basket of the present utility model chamber filter comprises housing, and this housing has import and outlet.Be provided with the basket cell-type filter cylinder that constitutes by protective cover, filtering net cylinder, support ring and handle in it, on the flange on its top top cover arranged.Its design feature is to be drilled with some through holes accordingly on the flange on housing top and the top cover, and the two tightens together by screw bolt and nut.

Because fastening with screw bolt and nut between the housing upper flange of basket of the present utility model chamber filter and top cover, the two can realize closely cooperating, the highly pressurised liquid in the housing can not exosmose.

Below in conjunction with drawings and Examples the utility model is described in further detail:

Fig. 1 is a basket of the present utility model chamber filter cross-sectional schematic;

Fig. 2 is the schematic top plan view of Fig. 1;

See Fig. 1, Fig. 2, basket of the present utility model chamber filter comprises a housing 1, its both sides, middle part have respectively as import 4 and outlet 15, with the flange that water delivery or oil pipeline join, this import and export communicates with housing 1 inner chamber.One basket cell-type filter cylinder is set in the housing 1, and this filter cylinder has two-layer, and internal layer is a filtering net cylinder 3, and skin is a protective cover 2; The upper end of filtering net cylinder 3 and protective cover 2 is screwed on support ring 5, fixes a handle 6 on the support ring, is easy to basket cell-type filter cylinder is taken out when making things convenient for scarfing cinder.It is to spend that the size of handle 6 should make its top and top cover offset.During assembling, the support ring 5 of basket cell-type filter cylinder is placed on the annular boss of middle and upper part in the housing 1 naturally, and basket cell-type filter cylinder is not touched with the inwall and the bottom connection of housing 1.Housing 1 top has as the flange that takes, puts basket cell-type filter cylinder, is furnished with top cover 11 on this flange, flange face circumferentially and top cover 11 circumferentially process six through hole (see figure 2)s accordingly, and housing 1 upper flange and top cover 11 are tightened together by means of bolt 7, pad 8 and nut 9.Top cover 11 upper surfaces also are welded with two and are convenient to portable handgrip 10.Bottom one side of housing 1 also is processed with a screw that communicates with its inner chamber, is furnished with plug 16 in the screw, removes with convenient being easy to when in the housing 1 sediment being arranged.

Bolt 7 in the foregoing description can be an eyelet bolt.When adopting eyelet bolt, the hemispherical counterbore is processed in the through hole at the housing 1 upper flange face back side, so that match with the movable joint head of eyelet bolt.Be drilled with the axial perpendicular through hole with eyelet bolt on the movable joint head of eyelet bolt, the movable joint headgear that makes eyelet bolt by this through hole is on annular bearing pin 13.Wherein annular bearing pin 13 is made up of two semicircle bearing pins, and is fastened to the back side of housing 1 upper flange face by means of screw 12 and stay hook 14.In addition, the bottom of housing 1 can be flat, can be at the bottom of the hemispherical, also can make other different shape.

In the foregoing description, the filter area of filtering net cylinder 3 and import 4 or the ratio that exports 15 inside nominal diameter are greater than 10 times.
