Summary of the invention

[0005] In order to improve the problem that larger impurities are easily accumulated in the diversion device and cause blockage, the present application provides a municipal drainage rainwater and sewage diversion treatment device.

[0007] By adopting the above technical solution, sewage is discharged to the sewage treatment plant through the sewage pipe, so as to treat the sewage. When it rains, rainwater mixed with impurities flows through the wellhead, flows into the drain pipe through the rotating component, and the rainwater flowing into the drain pipe falls into the conical filter. At the same time, the rotating part is started, and the rotating part drives the conical filter to rotate. During the rotation of the conical filter, the rainwater and impurities can be centrifugally filtered.

After that, some impurities that are not filtered flow through the sewage pipe to the sewage pipe, and then flow into the sewage treatment plant. Compared with the related art, the present application drives the conical filter to rotate by a rotating part to centrifugally filter rainwater and impurities. Since impurities of different particle sizes have different motion trajectories and speeds in the conical filter, more precise separation can be achieved. Subsequently, some impurities that are not filtered flow along the sewage pipe into the sewage treatment plant, which is conducive to improving the problem that larger impurities are easily accumulated in the diversion device and cause blockage.

[0008] Optionally, the second filter assembly includes a first filter plate, the first filter plate is tilted and located at the connection between the drain pipe and the sewage pipe, the first filter plate is tilted and arranged downward from the drain pipe to the sewage pipe, the lower end of the first filter plate is fixed to the sewage pipe away from the fixing plate, the higher end of the first filter plate is fixed to the drain pipe, the filter holes of the first filter plate are smaller than the filter holes of the conical filter screen, and the first filter plate separates rainwater and impurities; The sewage guide pipe is arranged obliquely, and the sewage guide pipe is arranged obliquely downward from the drainage pipe to the sewage discharge pipe.

[0011] By adopting the above technical scheme, when rainwater and unfiltered impurities flow to the first filter plate and the first sewage sensor senses sewage, the first sewage sensor transmits a signal to the closing shaft, and then the closing shaft drives the arc plate to rotate toward the side away from the sewage pipe, and the arc plate opens the connection between the drain pipe and the sewage pipe, and the rainwater falls on the first filter plate with impurities, and the impurities flow into the sewage pipe along the sewage pipe; when the first sewage sensor does not sense sewage, the sewage sensor transmits a signal to the closing shaft, and then the closing shaft drives the arc plate to rotate toward the side close to the sewage pipe, and the arc plate can close the connection between the drain pipe and the sewage pipe. At this time, rainwater flows into the river through the first filter plate along the drain pipe.

At this time, the rotating plate 4335 drives the transmission rod 4331 to rotate, and then the transmission rod 4331 drives the rotating shaft 431 to rotate, which can rotate the conical filter 42 to centrifugally filter the rainwater. Since impurities of different particle sizes have different motion trajectories and speeds in the conical filter 42, more refined separation can be achieved.

[0039] Reference Figure 6 , Figure 7 and Figure 8The second filter assembly 5 is located at the connection between the drain pipe 21 and the sewage pipe 22. The second filter assembly 5 includes a first filter plate 51, a closing member 52, a first sewage sensor 53, a second filter plate 54, a blocking member 55 and a second sewage sensor 56.

The filter hole of the first filter plate 51 is larger than the cone. The filter holes of the shaped filter 42 are small, and the first filter plate 51 separates rainwater and impurities. The closing member 52 is located above the first filter plate 51. The closing member 52 includes a closing shaft 521, an arc plate 522 and two connecting rods 523.

The first sewage sensor is electrically connected to the closing shaft 521 through a controller. When the first sewage sensor 53 senses sewage, the first sewage sensor 53 transmits a signal to the closing shaft 521. Subsequently, the closing shaft 521 drives the arc plate 522 to rotate toward the side away from the sewage pipe 22. The rainwater carries impurities and falls on the first filter plate 51. The impurities flow into the sewage pipe 12 along the sewage pipe 22. When the first sewage sensor 53 does not sense sewage, the sewage sensor transmits a signal to the closing shaft 521. Subsequently, the closing shaft 521 drives the arc plate 522 to rotate toward the side close to the sewage pipe 22. The arc plate 522 can close the connection between the drain pipe 21 and the sewage pipe 22. At this time, rainwater flows into the river along the drain pipe 21 through the first filter plate 51; the drain pipe 21 is fixedly connected with a rain sensor 212 at the connection between the drain pipe 21 and the sewage pipe 22 by screws, and the rain sensor 212 is electrically connected to the closing shaft 521. When the rain sensor 212 senses a large amount of water, the rain sensor 212 transmits a signal to the closing shaft 521, and the closing shaft 521 drives the arc plate 522 to rotate toward the side away from the sewage pipe 22, and rainwater can flow into the sewage pipe 22 and the drain pipe 21 at the same time; conversely, the arc plate 522 can close the connection between the drain pipe 21 and the sewage pipe 22, and rainwater flows into the river along the drain pipe 21.

[0041] Reference Figure 6 , Figure 7 and Figure 8The second filter plate 54 is located in the sewage pipe 22. The setting direction of the second filter plate 54 is parallel to the axial direction of the sewage pipe 22. A filter port 221 is provided at the bottom of the sewage pipe 22. A conduit 222 is welded at the filter port 221 of the sewage pipe 22. One end of the conduit 222 is connected to the sewage pipe 22, and the other end is connected to the river.

The blocking member 55 includes a receiving box 5 51, a blocking plate 552 and a telescopic rod 553, a receiving opening 223 is provided at the top of the sewage pipe 22, and the receiving opening 223 is close to the lower end of the filter opening 221, and the receiving box 551 is open, and the receiving box 551 is located above the sewage pipe 22, and the receiving box 551 opening faces the receiving opening 223, and the receiving box 551 opening fits with the receiving opening 223, and the receiving box 551 is welded to the sewage pipe 22, and the blocking plate 552 and the telescopic rod 553 are both located at the receiving opening 223. In the box 551, the blocking plate 552 is slidably connected to the containing box 551, the telescopic rod 553 is vertically arranged, one end of the telescopic rod 553 is welded to the containing box 551, and the other end is welded to the blocking plate 552, the second sewage sensor 56 is fixedly connected to the inner wall of the sewage pipe 22 by screws, and the second sewage sensor 56 is electrically connected to the telescopic rod 553. When the second sewage sensor 56 detects sewage, the second sewage sensor 56 transmits a signal to the telescopic rod 553, and the telescopic rod 553 pulls the blocking plate 552 to move toward the side close to the containing box 551, and the sewage flows to the sewage pipe 12; when the second sewage sensor 56 does not detect sewage, the second sewage sensor 56 transmits a signal to the telescopic rod 553, and the telescopic rod 553 pushes the blocking plate 552 to move away from the containing box 551, and the blocking plate 552 fits with the bottom of the sewage pipe 22. At this time, when the amount of rainwater is large, the rainwater flows through the sewage pipe 22 to the conduit 222 and then merges into the river.

[0042] The implementation principle of a municipal drainage rainwater and sewage diversion treatment device in an embodiment of the present application is as follows: sewage is discharged to a sewage treatment plant through a sewage pipe network 11, and the sewage is treated. When it rains, rainwater falls on the ground. At this time, the drainage component 2 will adjust the position of the fan-shaped adjustment plate 322 according to the amount of water. Subsequently, the rainwater falls into the first filter component 4, and the first filter component 4 can separate the rainwater and impurities in the rainwater. At the same time, the rainwater starts the driving component 33, which can move the first filter component 4. When the first sewage sensor 53 in the second filter component 5 senses sewage, the closing component 52 opens the connection between the drain pipe 21 and the sewage pipe 22, so that the sewage and impurities flow into the sewage pipe 12 along the sewage pipe 22. When the first sewage sensor 53 does not sense sewage, the closing component 52 closes the connection between the drain pipe 21 and the sewage pipe 22, and the rainwater falls into the drain pipe 21, and the rainwater flows to the river through the drain pipe 21.

[0043] When draining water on rainy days, the induction element 34 will sense the amount of water, and the induction element 34 will transmit the signal to the driving motor 331. The driving motor 331 can adjust the gap between the two adjacent fan-shaped fixed plates 321 to facilitate drainage on rainy days. The rain falls into the conical filter 42. At the same time, the rain hits the rotating plate 4335. Then, the transmission rod 4331 drives the rotating shaft 431 to rotate. At this time, the blade 432 rotates with the rotating shaft 431 to chop the impurities. The conical filter 42 rotates to Filtering; when the amount of rainwater is large, the water volume sensor transmits a signal to the closing shaft 521. At this time, the closing piece 52 opens the connection between the drain pipe 21 and the sewage pipe 22, allowing the rainwater to flow into the sewage pipe 22 and the drain pipe 21 at the same time. The second sewage sensor 56 does not sense sewage. The second sewage sensor 56 transmits a signal to the telescopic rod 553. The telescopic rod 553 pushes the blocking plate 552, so that the rainwater entering the sewage pipe 22 can flow from the filter port 221 to the conduit 222, and finally flow into the river.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
