Description

Technical Field

[0001] This utility model relates to the field of sewage interception devices, specifically a drainage sewage interception device. Background Technology

[0002] In municipal construction, sewage interception is a crucial task, directly related to the improvement of the urban water environment and the enhancement of residents' quality of life. As an important component of municipal infrastructure, urban water supply and drainage interception projects play a vital role in creating a good urban living environment and controlling the quality of urban drinking water.

[0003] Existing wastewater interception methods typically use filter plates to intercept impurities in wastewater. However, during use and observation, it has been found that filter plates need to be replaced after a long period of use. This requires disassembling the device and removing a large number of bolts, increasing the complexity of the filter plate replacement operation.

[0004] Therefore, a drainage and sewage interception device is proposed to address the above problems. Utility Model Content

[0007] Preferably, a second drain pipe is connected to the middle of the box body; a pair of second filter plates are fixedly connected to the middle of the rotating shaft; the second filter plates are located between the sealing plate and the first filter plate; the second drain pipe and the first drain pipe are located on the same side of the box body; through the cooperation of the second filter plates and the second drain pipe, rotating the rotating shaft will cause the second filter plates to come into contact with the box body, which will cause sewage to be discharged from the first drain pipe and the second drain pipe at the same time, reducing the drainage pressure of the first drain pipe and the filtration pressure of the first filter plate, and improving the device's ability to intercept sewage.

[0008] Preferably, a cleaning plate is fixed to the inner wall of the box; the surface of the cleaning plate is porous; a cleaning pipe is connected to the middle of the cleaning plate; the cleaning pipe and the box are connected through each other; the cleaning pipe and the water inlet pipe are located on the same side of the box; when the operator replaces the two first filter plates, the operator can connect a water pump to the cleaning pipe to allow cleaning water to enter the cleaning pipe and spray out from the surface of the cleaning plate. The cleaning water will reach the surface of the contaminated first filter plate and rinse its surface, reducing the impurities accumulated on the surface of the first filter plate, realizing the cleaning of the first filter plate by the device, and improving the convenience of cleaning the first filter plate by the device.

[0009] Preferably, a guide plate is fixedly connected to the middle of the upright plate near the cleaning plate; the guide plate and the box body are also fixedly connected; the middle of the guide plate is perforated; the guide plate has an arc-shaped structure; when the second drain pipe is open, sewage will pass through the gap between the upright plates and reach the cavity between the cleaning pipe and the second drain pipe. The guide plate will block the sewage and reduce the direct contact between the sewage and the cleaning plate. When cleaning the first filter plate, the cleaning water sprayed from the cleaning plate will reach the surface of the guide plate. Some of the cleaning water will spray out from the holes in the middle of the guide plate, and the rest of the cleaning water will spray out from the edge of the guide plate, increasing the flow range of the cleaning water.

[0010] Preferably, the inner sidewall of the box is symmetrically rotatably connected with baffles; the baffles and the box are connected by torsion springs; the baffles and guide plates are correspondingly arranged; when sewage flows from the upper and lower ends of the guide plate to the cleaning plate, the baffles will adhere to the ends of the guide plates under the action of the torsion springs and seal the two sides of the guide plates, further reducing the sewage from contaminating the cleaning plate, while the cleaning water sprayed from the cleaning plate will impact the surface of the baffles under the action of water pressure, causing the baffles to rotate along the box, reducing the obstruction of the cleaning water by the baffles.

At the same time, because the sealing gasket has an arc-shaped structure, the resistance when the sealing gasket comes into contact with the upright plates and the box is smaller, which improves the sealing gasket's ability to fill gaps.

The cleaning water will reach the contaminated surface of the first filter plate 17 and rinse its surface, reducing the impurities accumulated on the surface of the first filter plate 17, realizing the cleaning of the first filter plate 17 by the device, and improving the convenience of cleaning the first filter plate 17 by the device.

[0029] Please see Figure 3 As shown, a guide plate 4 is fixedly connected to the middle of the upright plate 18 near the cleaning plate 32; the guide plate 4 and the box body 1 are also fixedly connected; the middle of the guide plate 4 is perforated; the guide plate 4 has an arc-shaped structure; when the second drain pipe 22 is in the open state, the sewage will pass through the gap between the upright plates 18 and reach the cavity between the cleaning pipe 3 and the second drain pipe 22. The guide plate 4 will block the sewage and reduce the direct contact between the sewage and the cleaning plate 32. When cleaning the first filter plate 17, the cleaning water sprayed from the cleaning plate 32 will reach the surface of the guide plate 4. Some of the cleaning water will spray out from the hole in the middle of the guide plate 4, and the rest of the cleaning water will spray out from the edge of the guide plate 4, increasing the flow range of the cleaning water.

[0030] Please see Figure 3 and Figure 5As shown, baffles 5 are symmetrically rotatably connected to the inner sidewall of the box 1; baffles 5 and box 1 are connected by torsion springs; baffles 5 and guide plates 4 are correspondingly arranged; when sewage flows from the upper and lower ends of guide plates 4 to cleaning plates 32, baffles 5 will adhere to the ends of guide plates 4 under the action of torsion springs and seal both sides of guide plates 4, further reducing the pollution of cleaning plates 32 by sewage, while the cleaning water sprayed from cleaning plates 32 will impact the surface of baffles 5 under water pressure, causing baffles 5 to rotate along box 1, reducing the obstruction of cleaning water by baffles 5.

[0031] Please see Figure 3 As shown, multiple elastic rods 6 are fixed to the inner sidewall of the box 1; a ball 62 is fixed to the end of the elastic rod 6; the ball 62 and the second filter plate 2 and the first filter plate 17 are arranged correspondingly; when the rotating shaft 15 rotates, it will drive the first filter plate 17 and the second filter plate 2 to rotate and make them contact the elastic rods 6 and the ball 62. When the ball 62 contacts the first filter plate 17 and the second filter plate 2, it will vibrate under the impact, reducing the impurities accumulated on its surface.

[0033] Please see Figure 4 As shown, the adjacent sealing plate 16 and the first filter plate 17 are arranged vertically; the surface of the sealing gasket 7 is an arc-shaped structure; because the sealing plate 16 and the first filter plate 17 are arranged vertically, when the sealing plate 16 seals the upright plate 18, the two first filter plates 17 just contact the side wall of the box body 1, which improves the stability of sewage interception after the first filter plate 17 is switched. At the same time, because the sealing gasket 7 is an arc-shaped structure, the resistance when the sealing gasket 7 contacts the upright plate 18 and the box body 1 will be smaller, which improves the sealing gasket 7's ability to fill gaps.

[0034] Working principle: Wastewater is discharged into the housing 1 through the inlet pipe 12. The wastewater passes through the first filter plate 17 and is discharged from the first drain pipe 13. The sealing plate 16 contacts the vertical plate 18 and forms a sealing structure, allowing the wastewater to flow stably in the cavity between the inlet pipe 12 and the first drain pipe 13. The first filter plate 17 intercepts impurities in the wastewater. When too many impurities accumulate on the surface of the first filter plate 17, the operator can start the motor 14 to rotate the shaft 15. The shaft 15 will cause the first filter plate 17 and the sealing plate 16 to rotate. At this time, the blocked first filter plate 17 will be swapped with another first filter plate 17, realizing the device's rapid replacement of the first filter plate 17. When the water pressure at the first drain pipe 13 is high, the operator can... The startable motor 14 causes the rotating shaft 15 to drive the second filter plate 2 to rotate together. When the second filter plate 2 contacts the side wall of the box 1, a gap will appear between the sealing plate 16 and the upright plate 18. At this time, the cavities on both sides of the upright plate 18 will be connected. After the sewage enters the box 1, it will be filtered by the two second filter plates 2 and finally discharged from the second drain pipe 22 and the first drain pipe 13 respectively. The cleaning pipe 3 and the water inlet pipe 12 are located on the same side of the box 1. When the staff replaces the positions of the two first filter plates 17, the staff can connect an external water pump to the cleaning pipe 3 to allow cleaning water to enter the cleaning pipe 3 and spray it out from the surface of the cleaning plate 32. The cleaning water will reach the contaminated surface of the first filter plate 17 and rinse its surface, reducing the impurities accumulated on the surface of the first filter plate 17. The device cleans the first filter plate 17. When the second drain pipe 22 is open, sewage passes through the gap between the vertical plates 18 and reaches the cavity between the cleaning pipe 3 and the second drain pipe 22. The guide plate 4 blocks the sewage, reducing direct contact between the sewage and the cleaning plate 32. When cleaning the first filter plate 17, the cleaning water sprayed from the cleaning plate 32 reaches the surface of the guide plate 4. Some of the cleaning water sprays out from the central hole of the guide plate 4, and the rest sprays out from the edge of the guide plate 4. When sewage flows from the upper and lower ends of the guide plate 4 to the cleaning plate 32, the baffle 5, under the action of the torsion spring, adheres tightly to the end of the guide plate 4 and seals both sides of the guide plate 4, further reducing the contamination of the cleaning plate 32 by sewage. The cleaning water sprayed from the cleaning plate 32... The clean water impacts the surface of the baffle 5 under water pressure, causing the baffle 5 to rotate along the box 1. When the rotating shaft 15 rotates, it drives the first filter plate 17 and the second filter plate 2 to rotate and come into contact with the elastic rod 6 and the ball 62. When the ball 62 comes into contact with the first filter plate 17 and the second filter plate 2, it vibrates under the impact. When the sealing plate 16 comes into contact with the upright plate 18, the sealing gasket 7 also comes into contact with the upright plate 18. The sealing gasket 7 fills the gap between the sealing plate 16 and the upright plate 18, improving the airtightness of the connection between the sealing plate 16 and the upright plate 18. When the first filter plate 17 and the second filter plate 2 come into contact with the box 1, the sealing performance is also enhanced by the filling effect of the sealing gasket 7. The surface of the sealing gasket 7 has an arc-shaped structure.Because the sealing plate 16 and the first filter plate 17 are vertically arranged, when the sealing plate 16 seals against the upright plate 18, the two first filter plates 17 are in contact with the side wall of the box body 1, improving the stability of sewage interception after the first filter plates 17 are switched. At the same time, because the sealing gasket 7 has an arc-shaped structure, the resistance is lower when the sealing gasket 7 contacts the upright plate 18 and the box body 1.
