Description

Rainwater separation and recovery device

technical field

The utility model relates to an energy-saving device, in particular to a rainwater separation and recovery device for separating sediment and floating objects in rainwater.

Background technique

The rainwater on the building flows into the municipal pipe network through the collection pipes. Due to the excessive impurities in the rainwater, most of them flow into the sewer and have not been effectively used. At present, the main method of using rainwater is to filter the sediment in the rainwater Filter it out so that the clean water flows into the storage tank through the pipeline for use, but this method only adopts the first-level separation to simply separate the sediment impurities and ignores the separation of the floating matter, and the floating matter is mainly in the pipe. The upper part of the wall flows, the particles are larger, and it is easier to block the pipe.

Utility model content

In order to solve the above problems, the utility model adopts a two-stage separation rainwater separation and recovery device

The utility model adopts the following technical solutions: a rainwater separation and recovery device, including a box body, the box body is divided into two-stage sedimentation chambers, the upper right of the box body is a second-stage sedimentation chamber, and the outer part of the second-stage sedimentation chamber The box part of the box is a first-level sedimentation chamber, the upper ends of the two sedimentation chambers are connected to each other, the upper left side wall of the first-level sedimentation chamber is provided with a water inlet, and the lower right side wall of the first-level sedimentation chamber is There is a drain port and a first filter screen on the top, the secondary sedimentation chamber is connected to the water inlet through the water inlet pipe, the water inlet pipe is provided with the water inlet of the first-stage sedimentation chamber, and the water inlet of the first-stage sedimentation chamber is set There is a float valve, and the right side of the secondary sedimentation chamber is provided with a clear water discharge port and a floating separation port. Located above the clear water outlet, the bottom of the secondary sedimentation chamber is provided with a through hole to communicate with the primary sedimentation chamber, the through hole is provided with a third filter, and the mesh number of the first filter is 150-200, the mesh number of the second filter net is 100-150, and the mesh number of the third filter net is 50-100.

The utility model adopts a two-stage separation chamber to separate sediment, and adds a floating object separation port in the secondary sedimentation chamber to separate floating objects in rainwater, which can effectively realize the separation of floating objects and sediment, dredge the pipeline, and recycle and clean of water resources.

Detailed ways

The rainwater separation and recovery device as shown in Figure 1 includes a box body 1, which is divided into two-stage sedimentation chambers, wherein the upper right of the box body 1 is a second-level sedimentation chamber 3, and the other parts of the box body 1 are The first-stage sedimentation chamber 2, the upper ends of the two sedimentation chambers are connected to each other, the upper left side wall of the first-stage sedimentation chamber 2 is provided with a water inlet 4-1, and the water inlet 4-1 is connected to the second-stage sedimentation chamber 3 through the water inlet pipe 4 , the lower right side wall of the primary settling chamber 2 is provided with a drain port 11, the drain port 11 is provided with a 170-purpose first filter screen 12, and the right side wall of the secondary settling chamber 3 is provided with a clear water discharge port 8 and The floating matter separation port 7 is opened in the upper section of the right side wall of the secondary sedimentation chamber 3, and the clean water discharge port 8 is opened in the middle section of the right side wall of the secondary sedimentation chamber 3 and is provided with a 65-mesh third filter screen 9. In order to allow rainwater to infiltrate slowly, the caliber of the clean water outlet 8 should be smaller than that of the water inlet 4-1, and the bottom of the secondary sedimentation chamber 3 has a through hole and a 115-mesh second filter screen 10. The primary sedimentation chamber The bottom of 2 is provided with a slope 13 .

Working process: rainwater enters the primary sedimentation chamber 2 from the water inlet 4-1 through the float valve 5, and flows to the drain outlet 11 under the action of the slope 13, and is infiltrated and discharged through the first filter screen 12. Due to the small mesh, it can only infiltrate discharge, causing the water level of the primary sedimentation chamber 2 to rise. When it reaches the float valve 5, the float valve 5 is closed, and the rainwater directly enters the secondary sedimentation chamber 3 through the water inlet pipe 4. A large amount of rainwater is filtered by the third filter net The clear water discharge port 8 is discharged and recycled into the water storage tank, and a small amount of water penetrates into the primary sedimentation chamber 2 through the second filter screen 10 on the through hole at the bottom of the secondary sedimentation chamber 3 to supplement the water discharged from the primary sedimentation chamber 2 through the drain port 11. Rainwater, in order to keep the water level stable so that the float valve 5 is in a normally closed state. When there are many floating objects in the rainwater, it is blocked at the clean water discharge port 8 and the diameter of the water inlet is larger than that of the clean water discharge port 8. Therefore, the secondary sedimentation chamber The water level in 3 rises, and when the water level rises to the float separation port 7, the float is discharged from the float separation port 7, the pipeline is dredged, and the clean rainwater is continuously discharged from the clear water discharge port 8 without any influence. When floating matter is blocked at the outlet 11 in the primary sedimentation chamber 2, the water level in the primary sedimentation chamber 2 rises, and when it rises to the same level as the upper end of the secondary sedimentation chamber 3, the float flows into the secondary sedimentation chamber 3, thereby When the water level in the secondary sedimentation chamber 3 rises, the floating matter is separated and discharged from the floating matter separation port 7, so that the sediment and floating matter in the rainwater can be separated to obtain clean rainwater.
