Embodiment Construction
[0048] Refer to the following specific implementation methods Figure 1 to Figure 14 .
[0049]A rainwater filtering device provided with a sand discharge door, comprising a filter plate 20 installed in a filter box 10, on which several rows of filter holes 200 are provided; the filter plate divides the filter box into an upper chamber and a lower chamber, and the upper chamber A water outlet 101 is provided on the side wall of the chamber, and rainwater flows into the filter box through the top water inlet of the filter box; a sand discharge port is provided at the bottom of the filter box, and a sand discharge door is installed on the sand discharge port.
[0050] A plate frame 30 is slidably arranged on the side wall of the filter box, and a row of baffle plates 31 are arranged on the plate frame. The baffle plate is close to the bottom plane of the filter plate, and the baffle plate moving horizontally with the plate frame blocks the filter holes.
[0051] The filter plat...

The invention relates to a rainwater filtering plant with sediment ejection doors. The rainwater filtering plant comprises a filtering plate installed in a filtering box, wherein the filtering plate is provided with multiple rows of filtering holes; the filtering box is divided into an upper chamber and a lower chamber by the filtering plate, the side wall of the upper chamber is provided with a water outlet, and rainwater flows into the filtering box through a water inlet at the top of the filtering box; the bottom of the filtering box is provided with sediment ejection ports, and sediment ejection doors are installed on the sediment ejection ports; and the number of the sediment ejection doors is two, a first sediment ejection door in the two sediment ejection doors is hinged to left side of the bottom of the filtering box, a second sediment ejection door in the two sediment ejection doors is hinged to the right side of the bottom of the filtering box, and the first sediment ejection door and the second sediment ejection door in horizontal states seal the sediment ejection ports. When broken stones and sand grains in the lower chamber accumulate to a certain degree, the sediment ejection doors are opened, so that the broken stones and sand grains flow out of the filtering box through the sediment ejection ports.
Description
technical field [0001] The invention relates to urban infrastructure construction, in particular to the design of urban water storage and drainage equipment. Background technique [0002] Rainwater from the sky can be stored for later use, but the rainwater that falls on the ground is mixed with gravel and sand, so the rainwater that falls on the ground cannot be directly used for production or life. Contents of the invention [0003] The technical problem solved by the invention: how to remove gravel and sand grains in rainwater. [0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: a rainwater filtering device provided with a sand discharge door, including a filter plate installed in the filter box, and several rows of filter holes are opened on the filter plate; the filter plate divides the filter box into The upper chamber and the lower chamber have a water outlet on the side wall of the up...
