Embodiment

[0044] Such as Figure 1 to Figure 8 An emptying device is shown, which includes an emptying pipe 1 , a protective cover 2 , a filter element, a connecting cover 5 and a flow regulating valve 6 .

[0045] In this embodiment, the emptying pipe 1 is provided with an emptying passage for discharging the first rain, and the emptying pipe 1 is fixed in the waste flow device 7 . Wherein when being installed on the bottom wall of flow-discarding device 7, can adopt such as figure 2 In the arrangement shown, specifically, the emptying pipe 1 is vertically installed in the flow discarding device 7; and when installed on the side wall of the flow discarding device 7, such as image 3In the arrangement shown, specifically, the emptying pipe 1 is an L-shaped structure, the first end arm of the L-shaped structure is arranged vertically, and the second end arm of the L-shaped structure is arranged horizontally and passed through the side of the flow discarding device 7 on the wall. Aban...

Abstract

The invention discloses an emptying device comprising an emptying pipe, a filter piece and a protection cover. An emptying passageway used for discharging first rain is arranged in the emptying pipe.The emptying pipe is arranged in a flow abandoning device in a penetrating manner and fixed in the flow abandoning device. The filter piece is arranged on the emptying pipe in a sleeving manner and fixed to the emptying pipe. The protection cover is arranged on the emptying pipe and the filter piece in a covering manner. When the first rain falls into the flow abandoning device, due to the covering arrangement of the protection cover, the emptying pipe and the filter piece are sheltered from the first rain, the emptying pipe and the filter piece can be protected by the protection cover, the flow direction of the first rain can also be changed, the emptying route of the first rain is lengthened, and the impact of the first rain on the filter piece and the emptying pipe is reduced; the situation that part of pollutant is extremely likely to sink to the bottom of the flow abandoning device under the effect of the gravity of itself and it is avoided that the emptying pipe is blocked can happen, the situation that the other part of the pollutant is under the effect of the filter piece and it is avoided that the emptying pipe is blocked can also happen, and therefore the emptying efficiency and the emptying effect are ensured, dependence on manual work is small, and automatic emptying of the first rain can be achieved.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to an emptying device. Background technique [0002] Urban rainwater runoff has an obvious initial effect, that is, the concentration of pollutants in the runoff rainwater generated at the beginning of rainfall is very high. Therefore, when urban rainwater is used, it is necessary to discard the first rainwater, and a certain volume of runoff rainwater after the rainfall begins is regarded as the first rainwater. , Use a specific space to store the initial rain separately to achieve the separation effect, so as to obtain relatively clean later rainwater for environmental protection. [0003] In the prior art, the initial rainwater stored inside the first rain abandonment device is emptied through the emptying valve at the bottom of the first rain abandonment device, and the emptying is performed by manually switching the emptying valve after each rainfall. In the proces...
