Description
Technical field
The utility model relates to rainwater harvesting technology field, particularly relates to a kind of rain water drainage filter.
Background technology
Along with developing rapidly of urbanization, the waterproof regional percentage in city continues to increase, and the runoff pollution formed by Urban Rain has become one of main source of current city water environment pollution.Originally clean natural rainfall, owing to being subject to road, square, the roofing even impact of airborne dust, makes it be rich in a large amount of impurity and pollutant, causes early stage water quality poor.If early-stage rainwater is directly entered nature receiving waters, very serious pollution will be caused to water body.If directly collected, its water quality not only affects rainwater-collecting and stores, and also improves the cost of production of rainwater subsequent treatment.Therefore, in the process of the water quality and environment of improving rainwater, abandoned stream process must be carried out to early-stage rainwater.
Utility model content
Technical problem to be solved in the utility model is: in order to overcome deficiency of the prior art, and the utility model provides a kind of rain water drainage filter, carries out abandoned stream filtration, automatic pollution discharge process to early-stage rainwater.
The utility model solves the technical scheme that its technical problem will adopt: a kind of rain water drainage filter, comprise mud sinking chamber well seat and abandoned stream strainer, described abandoned stream strainer is placed in described mud sinking chamber well seat, and described abandoned stream strainer two ends are connected with upstream line and downstream line respectively, the displacement of described upstream line and the displacement of downstream line are all greater than the displacement of described abandoned stream strainer.By size variable diameter design, make the laminar condition of current be transformed into turbulent condition, ensure solid pollutant abandoned stream, clean liquid falls into mud sinking chamber well seat bottom collection.
Further, in order to realize the connection of variable diameter design, also comprise upstream line bellmouth and downstream line bellmouth, described upstream line bellmouth and downstream line bellmouth are all arranged on described mud sinking chamber well seat sidewall, and described abandoned stream strainer two ends are connected with described upstream line and downstream line with downstream line bellmouth respectively by upstream line bellmouth.The connection of upstream line and downstream line and abandoned stream strainer is realized by the transition of upstream line bellmouth and downstream line bellmouth.
Further, the caliber of described upstream line bellmouth and downstream line bellmouth is all greater than the caliber of abandoned stream strainer.Realize reducing at upstream line bellmouth and downstream line socket and can ensure that the silt in rainwater prematurely precipitates, avoid the blocking of upstream line.
Further, described abandoned stream strainer comprises tube wall, and described tube wall comprises screen pack and abandoned stream board slot, and described abandoned stream board slot is positioned at the below of described screen pack, and described abandoned stream board slot both sides are connected with described screen pack both sides respectively.It is inner that abandoned stream strainer is horizontally installed on mud sinking chamber well seat, be abandoned stream board slot in the below of tube wall, top is screen pack, the foreign material precipitated can either be avoided to enter bottom mud sinking chamber well seat, and be conducive to sedimentary discharge, realize again the filtration of rainwater, improve the efficiency of filtering, not easily produce the situation of screen pack blocking.Early-stage rainwater stream abandoning filtration, automatic pollution discharge is realized by abandoned stream board slot and screen pack.
Further, in order to reach better filter effect, described screen pack and abandoned stream board slot are arc, and the arc range of described abandoned stream board slot is 0 °-270 °.
Concrete, the radian of described abandoned stream board slot is 60 °, 120 ° or 180 °.
Further, in order to realize the connection of abandoned stream strainer and upstream line bellmouth and downstream line bellmouth, described abandoned stream strainer also comprises two bellmouth links, the two ends of described tube wall are fixedly connected with described bellmouth link respectively, and described abandoned stream strainer is connected with described upstream line bellmouth and downstream line bellmouth respectively by described bellmouth link.Bellmouth link is convenient fixing, also has the effect supporting screen pack and abandoned stream board slot simultaneously.
Further, caliber due to abandoned stream strainer is less than the caliber of upstream line bellmouth and downstream line bellmouth, in order to realize connecting, the excircle of the junction of described bellmouth link and described upstream line bellmouth and downstream line bellmouth is provided with flange, the external diameter of described flange and the minor diameter fit of described upstream line bellmouth and downstream line bellmouth.Flange can make junction seal, and avoids the rainwater without filtering to enter follow-up gathering-device.
Further, in order to reduce the risk that upstream and downstream pipeline and abandoned stream strainer junction block, described flange and described bellmouth link are eccentric setting, being centrally located at directly over described bellmouth link center of described flange.Owing to containing a large amount of silt and foreign material in early-stage rainwater, a small amount of precipitation will inevitably be there is in rain early-stage rainwater before entering abandoned stream strainer, again because the caliber of upstream line bellmouth and downstream line bellmouth is greater than the caliber of abandoned stream strainer, therefore in order to avoid silt and the foreign material precipitation in abandoned stream filter inlet and exit, flange adopts eccentric setting, the flange of abandoned stream strainer lower end is designed less, decrease the accumulation of silt and foreign material.
Further, in order to make tube wall connect firm stable more, described tube wall is circumferentially with multiple ring stiffener, described reinforcing rib is fixedly connected with described tube wall.Because screen pack is net structure, its intensity is less, and easily distortion and damage, therefore make screen pack more solid by reinforcing rib, avoids distortion and damages.
Further, fix and be interconnected to make reinforcing rib, described tube wall is provided with multiple junction plate vertically, described junction plate is fixedly connected with described reinforcing rib.
Further, after realizing filtering, collect rainwater, also comprise rainwater collection collector, described rainwater collection collector is connected with the bottom of described mud sinking chamber well seat.By rainwater collection collector by rainwater-collecting in rainwater storage device.
Preferably, in order to increase the service life, described abandoned stream strainer adopts stainless steel material to make.Stainless steel material is also convenient to the later stage and is instead cleaned.
The beneficial effects of the utility model are: a kind of rain water drainage filter that the utility model provides, and the abandoned stream strainer adopting reducing to arrange makes the laminar condition of rainwater stream be transformed into turbulent condition, realize early-stage rainwater stream abandoning filtration, automatic pollution discharge; The rain early-stage split-flow adapted in varying environment situation by the design of the different proportion of screen pack and abandoned stream board slot is filtered; This device have functional strong, structure simple, filter efficiency advantages of higher.
