Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a vacuum mud discharge device. Background Art

[0002] In some biochemical pool construction sites, sludge pumping operations are often involved. Sludge pumping operations refer to the process of extracting the sludge inside the biochemical pool through a machine and discharging it to the outside to facilitate other construction steps. Submersible sewage pumps are often involved in the process of sludge pumping operations. Submersible sewage pumps can be directly installed inside the biochemical pool or sewage pool to extract sludge by diving below the liquid surface.

[0003] However, the existing mud pumping operation still has some defects. For example, the submersible sewage pumps used in some biochemical pool construction sites are often large submersible sewage pumps. Due to their large overall size and certain weight, they need to be installed inside the biochemical pool during installation, and it is also necessary to stop transporting sludge into the biochemical pool in advance to keep it empty, which hinders the overall progress of the mud pumping operation. In addition, the space of the biochemical pool is limited, and it is not easy to install a large submersible sewage pump in the limited space. The installation process is inconvenient and the large submersible sewage pump occupies a lot of the internal space of the biochemical pool. In addition, if the submersible sewage pump fails during operation, it needs to be pulled out of the biochemical pool for maintenance, and then reinstalled after the maintenance is completed, which is very time-consuming and consumes a lot of labor costs.

At the same time, the sludge 9 inside the semi-underground pool body 1 will also be sucked and flow upward to the first mud pumping pipeline 2011 and the second mud pumping pipeline 2012. At this time, the vacuum pressure gauge 3012 on the vacuum pipeline 301 is observed. If the vacuum pressure gauge 301 2 stabilizes and reaches the vacuum degree, the first dry pump 2021 and the second dry pump 2022 are turned on, and the first dry pump 2021 and the second dry pump 2022 extract the sludge 9 in the first sludge pumping pipeline 2011 and the second sludge pumping pipeline 2012 into the first conveying pipeline 2023 and the second conveying pipeline 2024, and the first conveying pipeline 2023 and the second conveying pipeline 2024 then convey the sludge 9 to the sewage main pipe 2025, and the sludge 9 finally flows to the thickening tank 5 through the sewage main pipe 2025;
