Embodiment Construction

[0019] refer to figure 1 , The preferred embodiment of the rainwater initial flow abandonment device of the present invention includes the flow abandonment actuator 11 and the composite flow filter 28 connected thereto.

[0020] refer to Figure 2 ~ Figure 3 , the said jettison executive mechanism 11 comprises a water inlet pipe 1, and the water inlet pipe 1 is connected with a section dirt chamber 18, and a basket grid 12 is arranged in the dirt interception chamber 18, and the basket grid 12 includes a basket and is positioned above the basket and connected with it Connected metal grille. The inner surface of the basket is provided with a percolation sludge barrier layer to block the solid sludge in the basket, and the liquid can seep out. The dirt intercepting chamber 18 is connected to the water flow direction control chamber 29, and the two share a casing. The water flow direction control chamber 29 is connected with the collecting pipe 6 and the discarding pipe 8 . A...

Abstract

An early rainwater drainage device comprises a water inlet pipe, a collecting pipe and a drainage pipe. The water inlet pipe is connected with a dirt-collecting chamber inside which a basket grid is arranged. A sludge obstructing layer is arranged inside a basket of the basket grid. The dirt-collecting chamber is connected with a flow direction controlling chamber which is further connected with the collecting pipe and the drainage pipe respectively. A plate valve switching mechanism is arranged inside the flow direction controlling chamber and comprises a plate valve shaft vertically fixed inside the flow direction controlling chamber and a valve plate arranged on the plate valve shaft. The size of valve plate is sufficient to cover the pipe mouths of the collecting pipe and the drainagepipe. The plate valve shaft is also connected with a motor outside the flow direction controlling chamber. The inventive early rainwater drainage device can pre-filter rainwater and the rainwater flow inside the collecting pipe or drainage pipe is controlled by the plate valve switching mechanism. The device is simpler in structure than the prior art.

Description

technical field [0001] The invention relates to a rainwater treatment device, in particular to a rainwater initial waste flow device for primary treatment of rainwater. Background technique [0002] With the continuous development of urban industrialization, the crisis of water sources and the hazards of rain and floods are becoming more and more serious. Collecting and utilizing rainwater as an important water resource and implementing comprehensive management of it have become an emerging topic that is widely concerned by the whole society. Because natural rainwater has the advantages of low hardness and less pollutants, it is very suitable for its collection, treatment and utilization, thereby effectively saving limited water resources. At present, the initial treatment of rainwater generally adopts the discarding device. The existing discarding device adopts the parallel connection of the collection pipe and the discarding pipe in the sewage pipe, and realizes the switch...
