Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

The embodiment relates to a sponge city rainwater purifier, as shown in figure 1, it is including having into rain mouthful 1 and row's rain mouthful 2 casing 3 to and locate in casing 3 and be located into rain mouthful 1 and arrange the swash plate between the rain mouthful 2, this swash plate is cascaded decline, and the interval has linked firmly a plurality of filter screens 4 on the swash plate, and constitutes impurity chamber 5 between filter screen 4 and the swash plate.

In the structure, the shell 3 is an internal hollow structure, the rain inlet 1 and the rain outlet 2 are respectively arranged on two opposite side walls of the shell 3, and the rain inlet 1 is higher than the rain outlet, so that rainwater can flow down along the inclined plate by the gravity of the rainwater. Through setting up a plurality of filter screens 4 in this embodiment to make filter screen 4 and swash plate constitute the impurity chamber, and then can make impurity filtered in impurity chamber 5, when impurity chamber impurity full or filter screen blockked up the back, the rainwater continues to be filtered by the filter screen of low reaches behind the impurity chamber rather than corresponding, has avoided having caused the influence because of filter screen 4 is blockked up.

Structurally, the swash plate is formed by a plurality of branch boards 6 end to end welding in proper order in this embodiment to be provided with foretell filter screen 4 respectively on each branch board 6, should divide board 6 to include riser 601, and be the horizontal plate 602 that the L type is connected with riser 601, and filter screen 4 links firmly in the side department of horizontal plate 602, and it encloses the aforesaid impurity chamber 5 that constitutes jointly with riser 601, horizontal plate 602, and filter screen 4 highly is less than the height of riser 601, so that the rainwater flows downstream.
