The invention discloses an initial rainwater recovery device, comprising: a shell, which is a closed cylinder with a hollow interior, the shell is composed of an upper shell and a lower shell fixedly connected together, the upper part of the upper shell A water inlet pipe is provided, and the lower part of the lower casing is provided with a clean water outlet pipe and a sundry outlet; the filter screen is arranged in the casing, and there is a certain gap with the inner wall of the casing, and the filter mesh is a cylinder with openings at both ends. Body, the bottom of the filter screen communicates with the debris discharge port; wherein, the connecting part of the water inlet pipe and the upper casing has a volute structure and is inserted into the upper casing from one side of the upper casing. The invention has simple structure, convenient use and maintenance, can quickly separate out sundries such as leaves and solid particles in rainwater, and discharge them from the sundry outlet, can make full use of rainwater and save water resources.
Description
technical field [0001] The invention relates to the technical field of rainwater collection and utilization, in particular to an initial rainwater recovery device. Background technique [0002] In the case of global freshwater scarcity, rainwater harvesting has become very important. Due to the great difference in the quality of rainwater in different periods during the rainfall process, and being affected by factors such as the atmosphere, building surfaces, and outdoor roads, the concentration of suspended matter and other pollutants in the initial rainwater is much higher than that in the middle and late rainwater. If no rainwater purification treatment is carried out It should not be used directly. [0003] The existing initial rainwater recovery device has complex design and low efficiency of impurity separation, and because it is buried underground, it is easily polluted by other pollution sources when not in use. Contents of the invention [0004] An object of the...
