Description

Technical Field

[0001] The utility model relates to the technical field of rainwater filtration, in particular to a filtering device for water supply and drainage. Background Art

[0002] With the rapid development of urbanization, the proportion of impermeable areas in cities continues to increase, and runoff pollution formed by urban rainfall has become one of the main sources of urban water environment pollution. The originally clean natural rainfall is affected by roads, squares, roofs and even air dust, making it rich in impurities and pollutants, resulting in poor water quality in the early stage. If the initial rainwater is discharged directly into the natural receiving water body, it will cause very serious pollution to the water body. If it is collected directly, its water quality will not only affect the collection and storage of rainwater, but also increase the production cost of subsequent rainwater treatment. Therefore, in the process of improving the water quality and environment of rainwater, the initial rainwater must be discarded through the municipal water supply and drainage filtration device.

[0003] A self-priming pump rainwater initial abandonment filter device mentioned in the existing Chinese public patent (authorization announcement number:). It includes a self-priming pump rainwater initial abandonment filter device. The existing rainwater initial abandonment filter device has high requirements on the size ratio of each structure in the device, which causes the device to be difficult to manufacture and the actual rainwater collection effect is not good. The following scheme is now proposed, which includes a self-priming pump and a collection pipe, the bottom end of the collection pipe is connected to a vertical pipe, and the two sides of the vertical pipe are respectively provided with a first through hole and a second through hole, and one end of the first conduit is installed in the second through hole, and the other end of the first conduit is connected to the water inlet end of the self-priming pump, and the water outlet end of the self-priming pump is installed with one end of the second conduit, and the other end of the second conduit is connected to a water storage tank. The utility model is easy to implement, the initial abandonment process of rainwater can be automatically completed, and the subsequent use of the self-priming pump can increase the speed of collecting rainwater, so as to avoid the speed of collecting rainwater by the device being excessively limited by the size of the pipe itself.

[0004] However, when the filter screen of the outlet pipe on the existing device is in use, a large amount of rainwater may carry debris and clog the filter screen, which not only affects the normal use of the filter screen, but also makes it difficult to clean the debris accumulated inside the device. Utility Model Content

[0005] The purpose of the present application is to solve the problem that impurities are difficult to clean and easily accumulate at the filter screen of the water outlet pipe of the municipal water supply and drainage filtering device. The present application provides a filtering device for water supply and drainage.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A filtering device for water supply and drainage, comprising a filter box, to which an inlet pipe is fixedly connected, to which an outlet pipe is fixedly connected, a partition plate is fixedly connected in the filter box, a sewage hole is opened on the partition plate, a sewage pipe is fixedly connected to the filter box, a filter frame is installed at the outlet pipe, and a cleaning structure is arranged between the filter box and the outlet pipe.

[0008] By adopting the above technical solution, when the device is used to filter rainwater, the debris in the rainwater will be blocked by the filter frame, and the larger debris will be left in the filter box, while the smaller debris will be affected by the cleaning structure and remain in the filter frame. This allows the device to filter rainwater through multi-layer filtering effects, so that the rainwater discharged from the outlet pipe contains less debris and is cleaner. After the device is used, the filter frame can be lifted upward by the cleaning structure, so that the debris accumulated in the device can be cleaned up in a timely and convenient manner, thereby reducing the impact of debris accumulation on the filtering work.

[0009] Furthermore, the cleaning structure comprises a mounting frame fixedly connected in the filter box, the mounting frame and the filter frame are slidably arranged, the filter frame is provided with filter holes, and the filter frame is fixedly connected with a handle.

[0010] By adopting the above technical solution, the installation frame can limit the position of the filter frame, thereby facilitating the installation and removal of the filter frame and making it easier to clean.

[0011] Furthermore, an arc-shaped filter plate is fixedly connected to the filter frame, the arc-shaped filter plate is matched with the water outlet pipe, and the filter holes on the arc-shaped filter plate are smaller than the filter holes on the filter frame.

[0012] By adopting the above technical solution, when the device is filtering rainwater, larger debris is blocked by the filter frame and remains on the partition plate, while smaller debris enters the filter frame and is blocked by the arc filter plate and remains at the bottom of the filter frame.

[0013] Furthermore, a threaded rod is rotatably connected to the partition plate, a lifting plate is threadedly connected to the threaded rod, and the lifting plate is in contact with the filter frame.

[0014] By adopting the above technical solution, the lifting plate can be driven to move by rotating the threaded rod, which makes it convenient for the device to move the filter plate to the upper end of the filter box, thereby facilitating cleaning personnel to clean up the debris therein.

[0015] Furthermore, the bottom side of the partition plate is rotatably connected to gear 2, and gear 2 is fixedly connected to the threaded rod. The bottom side of the partition plate is rotatably connected to gear 1, and gear 1 is meshed with gear 2. A rotating column is rotatably connected to the mounting frame, and the rotating column is fixedly connected to gear 1. A rotating plate is fixedly connected to the rotating column.

[0016] By adopting the above technical solution, the rotating plate drives the rotating column to rotate, thereby driving gear one to engage gear two to rotate, so that the threaded rod rotates, thereby driving the lifting plate to move, and allowing the filter frame to move upward.

[0017] Furthermore, a guide column is fixedly connected to the partition plate, and the guide column is slidably connected to the lifting plate.

[0018] By adopting the above technical solution, the lifting of the lifting plate is restricted by the guide column, thereby improving the lifting stability of the lifting plate.

[0019] Furthermore, a fixing rod is fixedly connected inside the filter box, a connecting rope 1 is fixedly connected to the fixing rod, a buoyancy ball is fixedly connected to one end of the connecting rope, two corresponding hemispherical plates are rotatably connected to the partition plate, the hemispherical plates are adapted to the sewage discharge holes, a connecting rope 2 is fixedly connected to the hemispherical plates, and the connecting rope 2 is fixedly connected to the buoyancy ball.

[0020] By adopting the above technical solution, when the rain is heavy, the buoyancy ball is affected by the buoyancy of the rain and moves upward, pulling the connecting rope to close the two hemisphere plates, so that the sewage pipe is closed, allowing rainwater with less impurities to be better discharged from the outlet pipe.

[0021] Furthermore, a driving motor is fixedly connected to the bottom side of the filter box, a crushing blade is fixedly connected to the output end of the driving motor, and the crushing blade is arranged inside the sewage discharge hole.

[0022] By adopting the above technical solution, the driving motor is started to drive the crushing blade to rotate, so as to break up the debris in the rainwater, making it easier to discharge the sewage through the sewage pipe and reducing blockage.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when the device is filtering rainwater, larger debris is blocked by the filter frame and remains on the partition plate, while smaller debris will enter the filter frame and be blocked by the arc filter plate and remain at the bottom of the filter frame. When the inside of the device is cleaned, the rotating plate drives the rotating column to rotate, thereby driving gear one to engage gear two to rotate, so that the threaded rod rotates and drives the lifting plate to lift the filter frame upward along the guide column. Then the cleaning staff pulls the handle to lift the filter frame and clean the debris therein. The size of the debris is separated by multi-layer filtration, which makes it difficult for the inside of the device to be blocked, improves the quality of rainwater discharged from the drain pipe, reduces the difficulty of cleaning the filter frame, and allows the cleaning staff to clean the accumulated debris more quickly, thereby reducing the impact of blockage caused by the accumulation of debris.

[0025] 2. In the present application, when the device is filtering rainwater, the driving motor is started when the rainwater is small to drive the crushing blade to rotate, thereby breaking up the debris in the rainwater and making it easier to discharge the sewage through the sewage pipe. In this way, the device is not easily blocked by debris during the sewage discharge process, thereby enhancing the sewage discharge effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a filtering device for water supply and drainage.

[0035] Reference Figure 1 and Figure 2 A filtering device for water supply and drainage includes a filter box 1, a water inlet pipe 2 is fixedly connected to the filter box 1, a water outlet pipe 3 is fixedly connected to the filter box 1, a partition plate 12 is fixedly connected in the filter box 1, a sewage hole is opened on the partition plate 12, a sewage pipe 4 is fixedly connected to the filter box 1, a filter frame 7 is installed at the outlet pipe 3, and a cleaning structure is arranged between the filter box 1 and the outlet pipe 3.

[0036] When the device is used to filter rainwater, rainwater will enter the filter box 1 through the water inlet pipe 2. When the rainwater starts to fall, the precipitation is small. At the same time, the rainwater will carry more debris from the sewage hole into the bottom of the filter box 1 and be discharged from the sewage pipe 4. As the rainwater continues to increase and the water volume increases, the debris mixed in it is also reduced, and the rainwater begins to flow to the outlet pipe 3. At this time, the debris in the rainwater will be blocked by the filter frame 7, leaving the larger debris in the filter box 1, while the smaller debris will be affected by the cleaning structure and remain in the filter frame 7. This enables the device to filter rainwater through multi-layer filtering effects, so that the rainwater discharged from the outlet pipe 3 has less debris and is cleaner. After the device is used, the filter frame 7 can be lifted upward by the cleaning structure, so that the debris accumulated in the device can be cleaned up in time and conveniently, thereby reducing the impact of debris accumulation on the filtering work.

[0037] Reference Figure 2 and Figure 3 The cleaning structure includes a mounting frame 6 fixedly connected to the filter box 1, the mounting frame 6 and the filter frame 7 are slidably arranged, the filter frame 7 is provided with filter holes, and the filter frame 7 is fixedly connected with a handle 8. The filter frame 7 is fixedly connected with an arc filter plate 11, the arc filter plate 11 is adapted to the outlet pipe 3, and the filter holes on the arc filter plate 11 are smaller than the filter holes on the filter frame 7. The partition plate 12 is rotatably connected with a threaded rod 21, and a lifting plate 23 is threadedly connected with the threaded rod 21, and the lifting plate 23 abuts against the filter frame 7. The bottom side of the partition plate 12 is rotatably connected with a gear 2 19, the gear 2 19 is fixedly connected with the threaded rod 21, and the bottom side of the partition plate 12 is rotatably connected with a gear 1 18, and the gear 1 18 is meshed with the gear 2 19. The mounting frame 6 is rotatably connected with a rotating column 9, the rotating column 9 is fixedly connected with the gear 1 18, and the rotating column 9 is fixedly connected with a rotating plate 10. A guide column 22 is fixedly connected to the partition plate 12 , and the guide column 22 is slidably connected to the lifting plate 23 .

[0038] When the device is filtering rainwater, larger debris is blocked by the filter frame 7 and remains on the partition plate 12, while smaller debris will enter the inside of the filter frame 7 and be blocked by the arc filter plate 11 and remain at the bottom of the filter frame 7. When the inside of the device is cleaned, the rotating plate 10 drives the rotating column 9 to rotate, thereby driving the gear 18 to engage the gear 2 19 to rotate, so that the threaded rod 21 rotates and drives the lifting plate 23 to lift the filter frame 7 upward along the guide column 22. Then the cleaning staff pulls the handle to lift the filter frame 7 and clean the debris therein. The size of the debris is separated by multi-layer filtration, which makes it difficult for the inside of the device to be blocked, improves the quality of rainwater discharged from the drain pipe, reduces the difficulty of cleaning the filter frame 7, and allows the cleaning staff to clean the accumulated debris more quickly, thereby reducing the effects of blockage caused by the accumulation of debris.

[0039] Reference Figure 2 and Figure 4 , Figure 5 A fixing rod 5 is fixedly connected in the filter box 1, a connecting rope 13 is fixedly connected to the fixing rod 5, a buoyancy ball 14 is fixedly connected to the end of the connecting rope 13, two corresponding hemispherical plates 15 are rotatably connected to the partition plate 12, the hemispherical plates 15 are adapted to the drainage hole, a connecting rope 2 16 is fixedly connected to the hemispherical plates 15, and the connecting rope 2 16 is fixedly connected to the buoyancy ball 14. A driving motor 20 is fixedly connected to the bottom side of the filter box 1, a crushing blade 17 is fixedly connected to the output end of the driving motor 20, and the crushing blade 17 is arranged inside the drainage hole.

[0040] When the device is filtering rainwater, when the rainwater is small, the driving motor 20 is started to drive the crushing blade 17 to rotate, so as to break up the debris in the rainwater, making it easier to discharge sewage through the sewage pipe 4 and reducing blockage. When the rainwater is large, the buoyancy ball 14 is affected by the buoyancy of the rainwater, thereby moving upward and pulling the connecting rope 16 to drive the two hemispherical plates 15 to close, so that the sewage pipe 4 is closed, and rainwater with less impurities can be better discharged from the outlet pipe 3, so that the device is not easily blocked by debris during the sewage discharge process, thereby enhancing the sewage discharge effect of the device.

[0041] Working principle: When the device is used for rainwater filtering, rainwater will enter the filter box 1 through the water inlet pipe 2. When the rainwater starts to fall, the precipitation is small, and the rainwater will carry more debris into the bottom of the filter box 1 from the sewage hole. At this time, the drive motor 20 is started to drive the crushing blade 17 to rotate, crush the debris in the rainwater, and discharge it from the sewage pipe 4;

[0042] As the amount of rainwater continues to increase, the amount of impurities mixed in it also decreases, and the rainwater begins to flow toward the outlet pipe 3. The buoyancy ball 14 is affected by the buoyancy of the rainwater, thereby moving upward and pulling the connecting rope 16 to close the two hemisphere plates 15, so that the sewage pipe 4 is closed, allowing the rainwater with less impurities to be better discharged from the outlet pipe 3. At this time, the larger impurities are blocked by the filter frame 7 and remain on the partition plate 12, while the smaller impurities will enter the filter frame 7 and be blocked by the arc filter plate 11 and remain at the bottom of the filter frame 7;

[0043] When cleaning the inside of the device, the rotating plate 10 drives the rotating column 9 to rotate, thereby driving the gear 18 to engage the gear 2 19 to rotate, so that the threaded rod 21 rotates and drives the lifting plate 23 to lift the filter frame 7 upward along the guide column 22. Then the cleaning staff pulls the handle to lift the filter frame 7 and clean the debris therein. The size of the debris is separated by multi-layer filtration, which makes it less likely for the inside of the device to be blocked, improves the quality of rainwater discharged from the drain pipe, and reduces the difficulty of cleaning the filter frame 7.
