Background technology
China is one of country of 13 serious water shortages in the world, along with rapid development of national economy, and the quick growth of population and the raising of living standards of the people, industry and urban domestic water increase considerably, and water resource day is becoming tight.Have only 0.28% freshwater resources to can be used as domestic water, agricultural water and water for industrial use on the earth, satisfy human needs.Because water resource inhomogeneous on spatial and temporal distributions, human in addition unreasonable development and use and serious waste to water resource, and in urbanization, course of industrialization increasing the weight of or the like pollution of waterhead, make that water contradiction is more and more outstanding.
Recently, people are to the rainwater utilization of natural water resources, more and more pay attention to, and the extensive utilization of rainwater resource is using water wisely, alleviate the city flood, alleviate the drainage pipeline burden, reduce pollutional load, improve the effective measures of water environment state.At present, more and more general to the collection utilization of rainwater both at home and abroad, rainwater is through certain filtration, and water uses in can be used as fully, even can also reach the standard of drinking water.Because collecting the gathering surface of rainwater all is open-air basically, various reasons can make rainwater be subjected in various degree pollution, and the direct utilization of this water is unsafe, also can produce adverse influence to environment, therefore, adopt suitable filter, it is necessary that the rainwater of collecting is filtered.
Summary of the invention
The object of the invention is to overcome the shortcoming that exists in the prior art, and a kind of rainwater cascade filtration device is provided, this device solves the problem that exists in the existing rainwater removal process, as polluting, the abandoned stream water yield is big, filter plant complex structure etc.
For achieving the above object, the present invention adopts following technical proposals:
A kind of rainwater cascade filtration device comprises filter house and the portion of being detained, and described filter house comprises shell body and ring-type screen pipe; Described shell body top is provided with water inlet, and the bottom is provided with delivery port, and the sidewall of shell body bottom is provided with the filtered water outlet; Touch to described ring-type screen pipe top and bottom coupling top and the bottom that is contained in shell body, and the water inlet of this shell body and delivery port are facing to the ring-type screen pipe mouth of pipe, the nozzle diameter of described ring-type screen pipe is greater than the water inlet diameter and the delivery port diameter of described shell body, and less than the diameter of described shell body.
The described portion of being detained is located at the below of filter house shell body, be one with the groove body structure of filter house shell body coupling, its groove body bottom is provided with sewage draining exit.
Further, the described set sewage draining exit place, portion bottom of being detained is provided with by-pass valve control.
Further, described ring-type screen pipe comprises internal layer screen pack, outer filter net and filtering material, and described filtering material is arranged between the inside and outside layer screen pack.Described internal layer screen pack will determine that if the outer filter host plays water guide and the fixedly effect of filtrate, the size of its mesh will be selected according to the granularity of filling filtrate according to filtering rainwater impurities granular size.Described filtering material is various water-purifying materials, and described filtering material is one or more the mixture in haydite, quartz sand, the fibrous nodules.
Further, be provided with the reinforcement sheet that is used to connect inside and outside layer screen pack between the described inside and outside layer screen pack, so that internal layer screen pack, outer filter net and filtering material are combined into a ring-type screen pipe, and strengthen the integral rigidity of this ring-type screen pipe.
After rainfall begins, contain the water inlet that the rainwater of leaf, dust granules is provided with by filter house shell body top, flow in the ring-type screen pipe, rainwater is under the effect of gravity, internal layer screen pack by the ring-type screen pipe carries out the filtration first time, and then carries out the second time through filtering material and filter, and rainwater is purified, set filtered water outlet flow in the storage tank on the sidewall of the logical shell body of rainwater after filtration bottom, and impurity such as leaf, dust granules then sink to the portion of being detained; When treating that impurity such as leaf, dust granules are stacked into to a certain degree, open the by-pass valve control that is arranged on the portion bottom blow-down mouth place of being detained, valve-off again after it is discharged continues by described ring-type screen pipe filtration rainwater.
The present invention is mainly used in rainwater and collects, and it is simple in structure, is provided with conveniently, and it is good to go out flowing water matter, is applicable to the rain water on roof offtake piping system in the building water supply and drainage field.
