Description

Pipeline filter

Technical field

The utility model belongs to chemical pipeline technical field, relates to a kind of filter, especially relates to a kind of pipeline filter.

Background technology

Pipeline is again piping filter with filter, mainly adapter, cylindrical shell, filter basket, flange, blind flange and securing member etc., consists of.Be arranged on pipeline and can remove the larger solid impurity in fluid, make machinery equipment (comprising compressor, pump etc.), instrument normally work and to turn round, reach stabilizing technical processes, the effect guaranteeing safe production.When liquid enters after filter basket by cylindrical shell, solid impurity particle is blocked in filter basket, and clean fluid is by filter basket, discharged by filter outlet.When needs clean, the supervisor bottom plug screw of outwarding winding, emptying fluid, dismounting blind flange, reloads after cleaning.Therefore, working service is very convenient.

But the fluid of existing piping filter directly impacts on filter basket or filtering screen, therefore cause a large amount of being gathered on filter basket or filtering screen of impurity particle, need to unpick and wash frequently filter, for producing, make troubles.

Utility model content

The purpose of this utility model is for the problems referred to above, and a kind of pipeline filter is provided; Solve prior art existing fluid and directly impacted the technical problem that filter screen or filtering screen, filter need to be unpicked and washed frequently.

For achieving the above object, the utility model has adopted following technical proposal: a kind of pipeline filter, the pipe-like body that comprises both ends open, described body one end seals with ellipse head, other end cover plate for sealing, on described body sidewall, be provided with a feed pipe and a discharge nozzle, described body interior is also provided with a right-angle elbow pipe, described right-angle elbow pipe one end and discharge nozzle sealing are connected, the other end and filtering screen are dismountable to be tightly connected, described filtering screen is positioned at body, described feed pipe is over against the corner of right-angle elbow pipe.

At above-mentioned pipeline, with in filter, described right-angle elbow pipe and the junction of filtering screen are provided with a retainer ring, and described retainer ring is fixedly connected with right-angle elbow pipe, and described filtering screen is enclosed within on retainer ring.

At above-mentioned pipeline, with in filter, described retainer ring comprises fixed head and is stationary pipes cylindraceous with fixed head is connected; Described filtering screen bottom is provided with a base plate, described base plate center has the first fixing hole matching with described stationary pipes aperture, and on described base plate and the edge that is positioned at the first fixing hole is also provided with a groove matching with fixed head size, shape.

At above-mentioned pipeline, use in filter, in described right-angle elbow pipe, be provided with a fixed leg, described fixed leg one end and right-angle elbow pipe inwall are connected, and the other end is through being arranged on second fixing hole at filtering screen top and being connected with filtering screen with the nut being enclosed within on fixed leg.

At above-mentioned pipeline, with in filter, on described cover plate, be provided with a safety valve.

At above-mentioned pipeline, with in filter, described ellipse head bottom is connected with a blow-off pipe.

Compared with prior art, the utility model has the advantage of: after fluid impact right-angle elbow pipe, flow to filtering screen, in the process of this impact, particle is deposited to the bottom of filter, greatly reduce the filter pressure of filtering screen, thereby can extend the service time of filter, reduce and unpick and wash frequency; When the safety valve arranging on filter can cause pressure jump when filter is plugged, realize pressure release, be convenient to the problem that producers find filter in time; The blow-off pipe of filter bottom setting can, in the situation that not taking filter apart, discharge solid particulate matter.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Fig. 5, a kind of pipeline filter, the pipe-like body 1 that comprises both ends open, ellipse head 13 sealings for described body 1 one end, cover plate 5 sealings for the other end, in the present embodiment, cover plate 5 is realized and being tightly connected by sealing ring 6 with body 1, on described body 1 sidewall, be provided with a feed pipe 3 and a discharge nozzle 4, described body 1 inside is also provided with a right-angle elbow pipe 8, described right-angle elbow pipe 8 one end and discharge nozzle 4 sealings are connected, the other end and filtering screen 2 is dismountable is tightly connected, described filtering screen 2 is positioned at body 1, described feed pipe 3 is over against the corner of right-angle elbow pipe 8.

Described right-angle elbow pipe 8 is provided with a retainer ring 7 with the junction of filtering screen 2, and described retainer ring 7 is fixedly connected with right-angle elbow pipe 8, and described filtering screen 2 is enclosed within on retainer ring 7.

Described retainer ring 7 comprises fixed head 71 and is stationary pipes 72 cylindraceous with fixed head 71 is connected; Described filtering screen 2 bottoms are provided with a base plate 22, described base plate 22 centers have the first fixing hole 21 matching with described stationary pipes 72 apertures, and on described the base plate 22 and edge that is positioned at the first fixing hole 21 is also provided with a groove 23 matching with fixed head 71 sizes, shape.

In described right-angle elbow pipe 8, be provided with a fixed leg 9, described fixed leg 9 one end and right-angle elbow pipe 8 inwalls are connected, the other end is through being arranged on second fixing hole 24 at filtering screen 2 tops and being connected with filtering screen 2 with the nut 91 being enclosed within on fixed leg 9, screwing nut 91 can be pressed in filtering screen 2 on retainer ring 7, thereby makes filtering screen 2 and retainer ring 7 realize face sealing.

On described cover plate 5, be provided with a safety valve 10, safety valve 10 can need to be selected the pressure of pressure release according to technique.

Described ellipse head 13 bottoms are connected with a blow-off pipe 11.

In use, fluid flows into from feed pipe 3, the corner of impacting right-angle elbow pipe 8, the solid that particle is larger is deposited in the decanting zone 12 of body 1 bottom in impact process, thereby has alleviated the filter pressure of filtering screen 2, can extend the service time of filter, reduce and unpick and wash frequency, 12 the solid particle in decanting zone, can discharge by blow-off pipe 11, under blow-off pipe 11 duties, can connect valve or with flange seal, when needs blowdown, open.When filter is blocked, because pressure needs to discharge, now, the safety valve 10 arranging on cover plate 5 can be opened pressure release automatically, also reminds producers change in time or unpick and wash simultaneously.
