Description

A kind of rainwater filtering device

Technical field

The utility model relates to rainwater recycle fields, and in particular to a kind of rainwater filtering device.

Background technique

Sponge city is the new concept that state key advocates construction, and it is main in sponge urban construction that rainwater recycle, which utilizes, Link.

Rainwater is filtered, collects, sterilizing, after the operation such as degerming using referring to by rainwater recycle, is collected to rainwater It uses, so that the waste of rainwater resource and the generation of rainwash are reduced, to reach supplement shortage of water resources and reduction The purpose that flood generates.

When collecting the rainwater of earth's surface, because at rainfall initial stage, the impurity as contained in the rainwater that rainfall is 2~5mm is such as Sandy soil are more, so that the rainwater in this stage, which generally requires, does abandoned stream processing.

In the prior art, it is net that the Chinese invention patent that Authorization Notice No. is CN105130055B discloses a kind of rainwater-collecting Change treatment for reuse system, which also discloses a kind of rainwater flow-discarding device, it includes: water inlet 3a, filter screen 3b be set into The top of mouth of a river 3a, water outlet 3c are set to the top of filter screen 3b.Floating ball 3d is correspondingly arranged at the lower section of water inlet 3a, and and spring Mechanism 3e connection, abandoned stream sewage draining exit 3f are correspondingly arranged at the lower section of floating ball 3d, and positioned at the bottom of rain water drainage filter device, rainwater is abandoned The bottom for flowing filter device is funnel-shaped.

In use, the rainwater effect into rainwater flow-discarding device is less than in the power on floating ball 3d when rainwater flow is smaller Spring mechanism 3e is to the active force of floating ball, so that abandoned stream sewage draining exit 3f is opened, to flow into the rainwater of rainwater flow-discarding device through abandoning Stream sewage draining exit 3f is expelled directly out, to achieve the purpose that abandoned stream.

But this rainwater flow-discarding device only can when rainfall continues smaller by the control of spring mechanism because of its abandoned stream The always on situation of abandoned stream sewage draining exit can be will appear, so as to cause in small rainfall rainwater flow-discarding device by rainwater all arrange Out, so as to cause the lesser rain fall of flow is directed to, whole rainwater-collecting purified treatment reclaiming system cannot work, therefore have There is room for improvement.

Utility model content

In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of rainwater filtering device, the rainwater Filter device can still provide for filtration treatment when rainwater flow is smaller, have the advantages that applicability raising.
