Summary of the invention
The utility model purpose 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 utility model 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 utility model 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.
