Abstract

The utility model discloses a direct through typed filter device used for a conveying pipeline, comprising a shell; the shell consists of two parts which are butted to each other; the shell is internally provided with a filter net which is a cylinder shape with one end of opening; the opening of the filter net faces to the output end of the shell; the net body extends toward the input end direction of the shell; the filter net is a taper with the diameter gradually contracted from the opening to the bottom; the shell at the periphery of the filter net is also provided with an impurity collecting trough which is provided with a sewage outlet; the filter device adopts the conical cylindrical filter net which is fixed inside the shell by a straight through way; when in use, the filtrated impurities can slide into the collecting trough on the shell through the surface of the oblique filter net automatically and are exhausted finally through the sewage outlet, thus achieving the object of self-cleaning of the filter net and bringing the convenience for the maintenance of the conveying pipeline.

Description

Conveyance conduit straight-through type filtrating equipment

Technical field

The utility model relates to the filtrating equipment that uses in a kind of conveyance conduit, and especially a kind of straight-through type is filtered system.

Background technique

The filtrating equipment that uses in the existing liquid conducting pipes mostly is conventional y-type filter greatly, its structure as shown in Figure 1, filter screen 1 is fixed in the filter by mounting flange, and during use, liquid flows into through filter screen 1 filtration back from filter one end and flows out from an end in the pipeline.Though its filter screen easy accessibility of this filter, but because filter screen itself does not have self-cleaning ability, impurity in liquid more for a long time, be easy to accumulate in the filter screen surface, cause the obstruction of filter screen, thereby must change continually in the using process, the cleaning and filtering net, bring very big inconvenience for the regular maintenance of pipeline.

The model utility content

At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of filter screen itself to have certain self-cleaning ability, and need not pull down the filtrating equipment that filter screen gets final product blowdown.

For achieving the above object, a kind of conveyance conduit of the utility model straight-through type filtrating equipment comprises housing, and this housing is made of two-part that butt joint connects, and housing is provided with for the input end and the output terminal that link to each other with conveyance conduit; Be provided with filter screen in the housing, this filter screen is the tubular of an end opening, and is provided with annular mounting disc at its opening, and the filter screen mounting disc is clamped on the two-part abutted flange face of housing, its opening is towards the housing output terminal, and its body extends to housing input end direction; Described filter screen is made of the filter screen that is positioned at inboard skeleton and be coated on the skeleton outer surface, filter screen integral body be diameter from its opening to its bottom diminishing taper, also be provided with the impurity collecting tank on the housing of filter screen periphery, this collecting tank place is provided with sewage draining exit.

Further, the bottom of described filter screen is a sphere shape, and filter screen and the coaxial setting of the housing of its place part.

The utility model filtrating equipment adopts taper tubular filter screen, and after adopting straight-through form to be fixed in the housing, in the using process, in the impurity that leaches can be under the disturbance of working fluid be slipped to collecting tank on the housing from the filter screen surface that tilts automatically, and finally discharge from sewage draining exit, thereby realize the self-cleaning of filter screen, for the maintenance of conveyance conduit brings convenience.

Fig. 2 is the utility model conveyance conduit straight-through type filter apparatus configuration schematic representation;

Fig. 3 is a filter screen structure schematic representation shown in the sequence number 4 among Fig. 2.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 2, the utility model filtrating equipment comprises housing, and its housing is made of left-half 2 and right half part 3 two-part that butt joint connects, and left half housing 2 is provided with output terminal, and right half housing 3 is provided with input end; Be provided with filter screen 4 in the housing, this filter screen 4 is the tubular of an end opening, and be provided with annular mounting disc 43 at its opening, filter screen mounting disc 43 is clamped on the abutted flange face of left and right sides two

halves housing

2,3, the opening of filter screen 4 is towards the housing output terminal, and its body then extends to housing input end direction.

As shown in Figure 3, filter screen 4 is made of inboard skeleton 42 and the filter screen 43 that is coated on skeleton 42 outer surfaces, filter screen 4 integral body be diameter from its opening to its diminishing taper in bottom, and its bottom is a sphere shape.

Filter screen 4 axis are concentric with the axis of the right half part housing 3 at its place.Also be provided with impurity collecting tank 5 on the housing of filter screen 4 peripheries, collecting tank 5 bottoms are provided with drain pipe 6, have valve 7 on the drain pipe 6.

During use, liquid enters housing from the input end on housing right side, filters the output terminal output of back from the housing left side through filter 4, and the impurity in the liquid then is left in the right half part housing 3.

Because of filter screen 4 whole tapered, and be installed in the housing so that direct-passing mode is coaxial, not only increase effective filter area, improved filter efficiency, and can by liquid by the time disturbance that produces impurity is fallen from the filter screen upper punch, avoid impurity the gathering of filter screen surface, guaranteed the stability of filter screen work.

In order to keep the filtrating equipment stable operation, the valve 7 that can regularly open on the drain pipe 6 is discharged the impurity in the collecting tank in the housing 5.

Structure when the filtrating equipment in the foregoing description is the level use, when with the filtrating equipment inlet opening last when being vertically mounted in the conveyance conduit, collecting tank 5 in the housing should be around the filter screen setting, and with the opening end of drain pipe 6 as close as possible filter screens, to guarantee effective discharge of impurity.

Claims

1. a conveyance conduit straight-through type filtrating equipment is characterized in that, comprises housing, and this housing is made of two-part that butt joint connects, and housing is provided with for the input end and the output terminal that link to each other with conveyance conduit; Be provided with filter screen in the housing, this filter screen is the tubular of an end opening, and is provided with annular mounting disc at its opening, and the filter screen mounting disc is clamped on the two-part abutted flange face of housing, its opening is towards the housing output terminal, and its body extends to housing input end direction; Described filter screen is made of the filter screen that is positioned at inboard skeleton and be coated on the skeleton outer surface, filter screen integral body be diameter from its opening to its bottom diminishing taper, also be provided with the impurity collecting tank on the housing of filter screen periphery, this collecting tank place is provided with sewage draining exit.
