Description

Technical Field

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

[0002] The municipal drainage device is a drainage facility arranged under the road. It can discharge urban wastewater, rainwater and other precipitation out of the city to prevent urban waterlogging. The municipal drainage device is an integral part of the city's overall planning. The urban drainage system usually consists of drainage pipes and sewage treatment plants. When the sewage and rainwater diversion system is implemented, the sewage is collected and discharged by the drainage pipes.

[0003] The sink and pipe of the current drainage system are fixedly connected. When sewage enters the pipe through the sink, small stones carried in the sewage will also enter the pipe with the water flow, which can easily cause the pipe to be blocked. Secondly, the pipe does not have the function of filtering the sewage passing through. The sewage filtered by the sink flows directly through the pipe, and the debris that is not completely filtered will enter the pipe. If it continues to operate like this, it will easily cause a lot of debris to accumulate in the pipe, reducing the sewage discharge capacity. Finally, the drainage pipe cannot block the odor in the pipe. When the weather is hot in summer, the odor of the sewage will drift out of the pipe and affect the surrounding environment. Therefore, a filtering device for municipal road water supply and drainage is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a filtering device for municipal road water supply and drainage to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A filtering device for municipal road water supply and drainage, comprises a sink, a connecting pipe and a shell, one end of the connecting pipe is fixedly connected to a box, a secondary filter screen and a tertiary filter screen are fixedly connected inside the box, a support rod is fixedly connected inside the box, a baffle is rotatably connected to the bottom end of the box, a locking plate is fixedly connected to one side of the baffle, a bolt is fixedly connected to the bottom end of the box, a discharge port is provided at the bottom end of the box, an end of the box away from the connecting pipe is fixedly connected to a through pipe, a slide groove is provided on the inner side wall of the shell, a connecting block is slidably connected to the slide groove, one end of the connecting block is fixedly connected to a cover plate, the bottom end of the cover plate is fixedly connected to a rubber pad, and an end of the shell away from the through pipe is fixedly connected to a drain pipe.

[0007] Preferably, a primary filter is fixedly connected inside the lower water pool, and a connecting pipe is fixedly connected outside the lower water pool.

[0008] Preferably, the primary filter is arranged obliquely inside the lower water tank.

[0009] Preferably, there is a certain distance between the connecting pipe and the bottom of the lower pool.

[0010] Preferably, the distance between the cover plate and the rubber pad is larger than the diameter of the through pipe.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the sewage entering the pipeline can be filtered by the lower pool, the primary filter and the connecting pipe, and the debris can be blocked from entering the lower pool. After the small stones pass through the primary filter and enter the lower pool, since the connecting pipe is higher than the bottom of the lower pool by a certain height, the heavy objects such as small stones will remain in the lower pool and will not enter the pipeline with the water flow.

[0013] 2. In the utility model, the sewage entering the box can be filtered twice and three times by the provided box, secondary filter screen, tertiary filter screen, baffle, lock plate and bolts, so as to remove the debris in the sewage as much as possible. The filtered debris will fall to the bottom of the box. After a certain amount of debris is accumulated, the baffle can be opened to take out the debris from the discharge port;

[0014] 3. In the utility model, the shell, slide, cover, rubber pad, connecting block and through pipe are provided, so that the through pipe can be closed without affecting the discharge of sewage, and preventing the odor of sewage inside the pipe from escaping from the pipe and affecting the external environment.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A filtering device for municipal road water supply and drainage, comprising a sink 1, a connecting pipe 3 and a shell 13, one end of the connecting pipe 3 is fixedly connected to a box body 4, a secondary filter screen 5 and a tertiary filter screen 6 are fixedly connected inside the box body 4, a support rod 7 is fixedly connected inside the box body 4, a baffle plate 8 is rotatably connected to the bottom end of the box body 4, a locking plate 9 is fixedly connected to one side of the baffle plate 8, a bolt 10 is fixedly connected to the bottom end of the box body 4, a discharge port 11 is provided at the bottom end of the box body 4, a through pipe 12 is fixedly connected to one end of the box body 4 away from the connecting pipe 3, a slide groove 14 is provided on the inner side wall of the shell body 13, a connecting block 16 is slidably connected inside the slide groove 14, one end of the connecting block 16 is fixedly connected to a cover plate 15, a rubber pad 17 is fixedly connected to the bottom end of the cover plate 15, and a drain pipe 18 is fixedly connected to one end of the shell body 13 away from the through pipe 12.

[0025] A primary filter screen 2 is fixedly connected inside the lower water pool 1, and a connecting pipe 3 is fixedly connected to the outside of the lower water pool 1; the primary filter screen 2 is arranged obliquely inside the lower water pool 1; there is a certain distance between the connecting pipe 3 and the bottom end of the lower water pool 1; the distance between the cover plate 15 and the rubber pad 17 is larger than the diameter of the through pipe 12.

[0026] Working process: When the device is used, first make necessary tight connections between the various components of the device. When sewage needs to be discharged, the sewage enters from the sink 1 and will first pass through the primary filter 2. Since the primary filter 2 is inside the sink 1 and is arranged in an inclined manner, the sewage can be better filtered. Moreover, the primary filter 2 is inside the sink 1, and the filtered debris will remain on the surface of the primary filter 2 and will not be washed away by the sewage. Different from the existing sewage filtration, the sewage after the primary filtration enters the inside of the sink 1, and heavy objects such as small stones will remain at the bottom of the sink 1 and will not enter the pipe. The sewage will be discharged from the sink 1 through the connecting pipe 3, and the sewage will enter the box 4 through the connecting pipe 3. Under the filtration of the secondary filter 5 and the tertiary filter 6, the debris will be left in the box 4, and the support rod 7 supports the secondary filter 5 and the tertiary filter 6. It plays a supporting role. After the filtered debris accumulates to a certain amount in the box body 4, the nut on the bolt 10 is unscrewed, the baffle 8 is rotated, and the lock plate 9 is separated from the bolt 10. After the baffle 8 is opened, the debris will be discharged from the discharge port 11, and the filtered sewage will enter the shell body 13 through the L-shaped through pipe 12. A slide groove 14 is arranged inside the shell body 13, and the cover plate 15 slides up and down in the shell body 13 through the connecting block 16. When the sewage does not enter the shell body 13 from the through pipe 12, the cover plate 15 will be pressed on one end of the through pipe 12 under the action of gravity. The rubber pad 17 plays a sealing role to prevent odor from being discharged from the through pipe 12 and affecting the external environment. When sewage flows through the through pipe 12, the sewage will lift the cover plate 15, and the cover plate 15 will rise upward in the slide groove 14 through the connecting block 16, and then be discharged through the drain pipe 18 outside the shell body 13.
