Description

A kind of abandoned stream filter device

Technical field

The utility model relates to abandoned stream filtration art, specially a kind of abandoned stream filter device.

Background technique

Water is at normal temperatures and pressures the transparency liquid of colorless and odorless, referred to as the source of human life.The drinking water of the mankind Mostly from surface water and groundwater.Underground water --- organic matter and microbial contamination are less, and ion then dissolve it is more, it is usually hard Spend higher, distillation easy scaling when heating up water；Sometimes manganese fluorine ion is exceeded, is not able to satisfy production and living water demand.

Surface water --- it is more compared with underground water organic matter and microbial contamination, if the ground belongs to In Limestone Area, earth's surface Water often also has greater hardness, such as Deyang, Mianyang, Guangyuan, the Aba area in Sichuan.

Rainwater is one of the important sources of low water and surface water.The foundation of the low drainpipe in city, be exactly to rainwater into Row centralized collection converges in earth's surface lake or is lowly saving, and is the critical facility for saving urban water resource.But rainwater is on ground Surface low would generally sweep along a large amount of impurity when dynamic, result in blockage to drainpipe, be unfavorable for rainwater discharge, it is easy to form waterlogging.

Embodiment 1

Fig. 1~2, a kind of abandoned stream filter device, including shell 3 and abandoned stream valve 4 are please referred to, the shell 3 is top opening Type structure, the left-hand end top perforation connection water inlet 1 of shell 3, the right-hand end top perforation connection water outlet 2 of shell 3 are described Water outlet 2 and water inlet 1 be equipped on same straight line, in the middle part of the inner cavity of shell 3 respectively with 2 phase of water inlet 1 and water outlet The abandoned stream valve 4 of cooperation, the front end face bottom end perforation connection abandoned stream mouth 6 of abandoned stream valve 4, the other end of the abandoned stream mouth 6 run through shell 3 Side wall and overhang in outside, the filter screen matched respectively with water outlet 2 and abandoned stream valve 4 is equipped on the right side of the inner cavity of shell 1 5, the filter screen 5 is stainless steel material production, and rainwater enters 3 inner cavity of shell from water inlet 1 and passes through filter screen 5 from water outlet 2 It flows out, abandoned stream valve 4 is provided with inside shell 3, Rainfall runoff water in pipe network is collected when rainfall is small, water quality is not up in pipe network It is required to collecting, the more such water of impurity organic matter does not do collection direct emission in pipe network；Water hour water without filter screen 5, Directly through abandoned stream 4, flowed out from the abandoned stream mouth 6 on abandoned stream valve 4, be discharged to downstream pipe network, when pipe network run-off increases, abandoned stream mouth 6 with Water flow increases and becomes smaller until closing, and at this moment rainwater is flowed out through filter screen 5 from water outlet 2, is flowed to collecting pit, is filtered the miscellaneous of interception Matter stays in 3 inner cavity of shell, and rainfalls is waited to terminate to be discharged with abandoned stream mouth 6；Water reduces when rainfall stops, and abandoned stream mouth 6 reduces with water And become larger, the impurity for filtering interception is stayed with the discharge of abandoned stream mouth to down-pipe net.

Embodiment 2

The present embodiment is being further described on the basis of embodiment 1, and the shell 3 includes a bottom plate 7 and four Porous disc, the top end face edge of the bottom plate 7 are uniformly set there are four porous disc, are detachably to connect between four porous discs It connects, several permeable holes is uniformly equipped on porous disc, rainwater can be penetrated into the soil of surrounding by porous disc, prevent shell 3 stop rainwater to the supplement of soil moisture, influence the ecological environment in soil.

The working principle of embodiment 1-2 collects Rainfall runoff water in pipe network when rainfall is small, and water quality is not up in pipe network It is required to collecting, the more such water of impurity organic matter does not do collection direct emission in pipe network；Water hour water without filter screen 5, Directly through abandoned stream 4, flowed out from the abandoned stream mouth 6 on abandoned stream valve 4, be discharged to downstream pipe network, when pipe network run-off increases, abandoned stream mouth 6 with Water flow increases and becomes smaller until closing, and at this moment rainwater is flowed out through filter screen 5 from water outlet 2, is flowed to collecting pit, is filtered the miscellaneous of interception Matter stays in 3 inner cavity of shell, and rainfalls is waited to terminate to be discharged with abandoned stream mouth 6；Water reduces when rainfall stops, and abandoned stream mouth 6 reduces with water And become larger, the impurity for filtering interception is stayed with the discharge of abandoned stream mouth to down-pipe net.

The innovative point of the utility model is, by the way that abandoned stream valve 4 is arranged, is realized using the flow of rainwater to rain and impurity Filtering and the discharge of impurity, can effectively prevent rain and impurity blocking caused by drainage pipeline, and rainwater clear up automatically it is miscellaneous Matter reduces maintenance cost, reduces maintenance difficulties.

The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective Various changes can be made.
