Description

Primary sedimentation tank track type suction device

technical field

The utility model relates to a mud suction pipe for a primary sedimentation tank, in particular to a track type mud suction device for a primary sedimentation tank.

Background technique

At present, when domestic sewage and industrial sewage with high suspended solids are treated, primary sedimentation tanks are usually set up to pretreat the sewage to reduce the load on subsequent treatment facilities. At the same time, primary sedimentation tanks are also the most economical purification steps .

The dredging device of the existing primary sedimentation tank is usually a dredged main pipe connected to several dredged pipes, however, there are many deficiencies in this dredged method. On the one hand, if there is an air leak in one place of the dredged pipe, It will cause all the suction pipes to fail to suck mud; and if there is a blockage in one suction pipe, shutting down and cleaning will affect the work of other suction pipes, so that the whole suction dredge cannot work; on the other hand , when the suction pipe is blocked, it is difficult to clean up, and the pipe needs to be dismantled for flushing, which is difficult to clean and takes a long time to shut down. In addition, when the suction force is not enough, the mud suction pipe will not be able to suck the mud, and the mud will accumulate at the bottom of the pool, and when it accumulates to a certain thickness, the mud suction pipe will be stuck, causing the mud suction pipe to crack or break. Increase the maintenance workload and maintenance costs; and the current suction pipe is located under the suction main pipe, and the staff have to sit on the suction main pipe to check whether the suction pipe is unblocked, which is extremely inconvenient and increases the inspection work amount, consume a lot of manpower and material resources.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, the utility model provides a track-type mud suction device for the primary settling tank, which is used to discharge the sludge in the primary settling tank A into the sludge collection tank B. The track-type mud suction device for the primary settling tank Including a suction pipe 10, a ball valve 20, a butterfly valve 30, a vacuum pump 40 and an electric valve 50, the butterfly valve 30 is installed on the suction pipe 10, the ball valve 20 is installed on the suction pipe 10 and is located in front of the butterfly valve 30 On the side, the vacuum pump 40 is connected to the suction pipe 10 on the rear side of the butterfly valve 30 through a vacuum pipe 60. The vacuum pump 40 generates a vacuum by sucking the air in the suction pipe 10, and the electric valve 50 is arranged on the vacuum pipe 60. Siphon suction for cutting off suction pipes.

The dredging pipes 10 extend from the primary sedimentation tank A to the mud collecting tank B to siphon mud. In this embodiment, the number of the dredged pipes 10 is four, and the four dredged pipes 10 are arranged side by side at intervals. Ball valve 20 and butterfly valve 30 are all installed on each described suction pipe 10, and described butterfly valve 30 is used for opening or closing each corresponding suction pipe 10, and described ball valve 20 has good sealing performance, when one of them When the dredging pipe 10 is blocked, the dredging pipe 10 can be cleared by blowing air, and the blocked dredging pipe 10 can be dredged without dismantling the dredging pipe 10 for cleaning, which is easy to operate and will not affect To the normal work of other suction pipes 10. In this embodiment, the ball valve 20 is a DN25 ball valve, and the butterfly valve 30 is a DN80 butterfly valve.

One end of the vacuum pipe 60 is connected to the dredge pipe 10 at the rear side of the butterfly valve 30 , and the other end is connected to the vacuum pump 40 .
