Abstract

The utility model relates to a filtering device for an urban drainage pipeline, which comprises a water inlet pipeline and a water outlet pipeline, wherein a first filter passage and a second filter passage are arranged between the water inlet pipeline and the water outlet pipeline; the first filter passage and the second filter passage are communicated with the water inlet pipeline and the water outlet pipeline respectively; a first valve is arranged at a water inlet end of the first filter passage; a first filter screen is fixed at the middle of the first filter; a first pollution discharge port is arranged at one end, between the first valve and the first filter screen, near the first valve; a second valve is arranged at the water inlet end of the second filter passage. The filtering device for the urban drainage pipeline has the benefits that the structure is simple, the design is reasonable, impurities in the urban drainage pipelines can be effective filtered, the filtered impurities can be discharged from the pipelines conveniently, the operation is convenient and the use cost is low.

Description

Urban discharging pipeline filter

Technical field

The utility model relates to filter device for pipes, particularly a kind of urban discharging pipeline filter.

Background technology

Urban discharging pipeline collects sanitary sewage, waste water and rainwater and discharges, but in sanitary sewage, waste water and rainwater, contain a large amount of foreign material, very easily stop up the drainage pipeline networks in city, and then cause unnecessary trouble, although the filter arranging in urban discharging pipeline at present, although but these filters can filter foreign material, the cost of clearing up foreign material is higher, and use inconvenient.

Utility model content

For the defect existing in prior art, the purpose of this utility model is to provide a kind of urban discharging pipeline filter.

For reaching above object, the technical scheme that the utility model is taked is:

A kind of urban discharging pipeline filter, comprising: inlet channel and outlet conduit, arrange the first filtration channel and the second filtration channel between described inlet channel and outlet conduit; Described the first filtration channel and the second filtration channel respectively with inlet channel and outlet conduit UNICOM; The water inlet end of described the first filtration channel arranges the first valve; The middle part of described the first filtration channel is fixed with the first screen pack; One end near the first valve between described the first valve and the first screen pack arranges the first sewage draining exit; The water inlet end of described the second filtration channel arranges the second valve.

On the basis of such scheme, the middle part of described the second filtration channel arranges the second screen pack; One end near the second valve between described the second screen pack and the second valve arranges the second sewage draining exit.

On the basis of such scheme, the end of described inlet channel arranges first and screws button; The end of described outlet conduit arranges second and screws button.

The beneficial effects of the utility model: the filter that urban discharging pipeline described in the utility model is used, simple in structure, reasonable in design, not only can effectively filter foreign material in urban discharging pipeline, and convenient the foreign material that filter out are cleaned out to pipeline, easy to operate, use cost is low.

Brief description of the drawings

The utility model has following accompanying drawing:

Fig. 1 is the filter apparatus configuration schematic diagram described in the utility model embodiment 1;

Fig. 2 is the filter apparatus configuration schematic diagram described in the utility model embodiment 2;

Fig. 3 is the structural representation of the first screen pack described in the utility model and the second screen pack.

Detailed description of the invention

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

Embodiment 1

As shown in Figure 1, a kind of urban discharging pipeline filter, comprising: inlet channel 1 and outlet conduit 2, arrange the first filtration channel 3 and the second filtration channel 4 between described inlet channel 1 and outlet conduit 2; Described the first filtration channel 3 and the second filtration channel 4 respectively with inlet channel 1 and outlet conduit 2 UNICOMs; The water inlet end of described the first filtration channel 3 arranges the first valve 6; The middle part of described the first filtration channel 3 is fixed with the first screen pack 5; One end near the first valve 6 between described the first valve 6 and the first screen pack 5 arranges the first sewage draining exit 7; The water inlet end of described the second filtration channel 4 arranges the second valve 8.

When use, close the second valve 8, open the first valve 6, sewage enters the first filtration channel 3 from inlet channel 1, under the effect of the first screen pack 5, the foreign material in sewage is tackled; In the time that the foreign material on the first screen pack 5 are too much, close the first valve 6, open the second valve 8 and the first sewage draining exit 7, sewage carries out back-flushing by the second filtration channel 4 to the first screen pack 5, by the first screen pack 5 interception foreign material discharge the first filtration channel 3 by the first sewage draining exit 7, drained after, close as early as possible the first sewage draining exit 7, open the first valve 6, close the second valve 8 simultaneously, circulation said process filters and back-flushing process.

Embodiment 2

As shown in Figure 2, a kind of urban discharging pipeline filter, in the situation that other structures are identical with embodiment 1, arranges the second screen pack 12 at the middle part of described the second filtration channel 4; One end near the second valve 8 between described the second screen pack 12 and the second valve 8 arranges the second sewage draining exit 9.

When use, close the first sewage draining exit 7 and the second sewage draining exit 9, open the first valve 6 and the second valve 8 simultaneously, sewage enters respectively the first filtration channel 3 and the second filtration channel 4, the first screen pack 5 and the second screen pack 12 are tackled the foreign material in sewage simultaneously, in the time that the foreign material on the first screen pack 5 need to be cleared up, first close the first valve 6, open the first sewage draining exit 7, foreign material are discharged by the first sewage draining exit 7; In the time that the foreign material on the second screen pack 12 need to be cleared up, close the second valve 8, open the second sewage draining exit 9, foreign material are discharged by the second sewage draining exit 9.

For the ease of cleaning foreign material, the first sewage draining exit 7 and the second sewage draining exit 9 can be connected on the ground and carry out on the ground gauge tap, for the ease of the operation of whole device, the first valve 6 and the second valve 8 can be arranged on the ground.

Embodiment 3

As depicted in figs. 1 and 2, for the ease of the use of the device described in the utility model embodiment 1 and 2, can arrange in the end of described inlet channel 1 first and screw button 10, arrange second in the end of described outlet conduit 2 and screw button 11 simultaneously, when installation, only this device need be screwed by first to button 10 and second screws button 11 and urban discharging pipeline is connected and sealed.

With way of example, the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes of doing based on the utility model or modification all belong to the claimed scope of the utility model.
