Description

Technical Field

[0001] The utility model relates to the technical field of shield muck treatment, and specifically, to a shield muck slurry separation device. Background Art

[0002] A large amount of shield muck will be generated when tunneling through a shield machine. Since the construction water during the shield tunneling construction process and the formation seepage water during the shield tunneling process will both enter the shield muck, the shield muck generally has a large water content and is in a slurry state, which is not easy to transport. Therefore, it is necessary to carry out slurry separation treatment on the shield muck.

[0003] After retrieval, the utility model patent with the publication number of CN218944564U discloses a shield muck slurry separation device, including: a left box, guide plates arranged on both sides of the bottom end inside the left box, a conveying mechanism arranged in the middle upper part inside the left box, an auxiliary mechanism arranged in the upper right part inside the left box, a right box arranged on the right side of the left box, a vibration mechanism arranged inside the right box, a drying mechanism arranged above the right box, an upper outlet arranged in the upper right part of the right box, and a lower outlet arranged in the lower right part of the right box. When in use, the two cams continuously touch the filter screen, so that the muck on the filter screen vibrates again, and the water on the muck can be further filtered out. And with the cooperation of a group of heating plates and two fan blades, as the muck vibrates and overturns, it is convenient to dry the water on the muck, with thorough separation, high efficiency and good use effect.

[0004] The above patent has the following deficiencies: when the muck precipitates in the left box, the auger is located in the middle position of the left box, and it is not convenient to completely extract the precipitated muck through the auger; in addition, when the subsequent vibration slurry separation of the muck is carried out, it is not convenient to discharge the separated muck on the filter screen from the upper outlet, which affects the continuity and working efficiency of the muck separation. For this reason, we propose a shield muck slurry separation device. Summary of the Utility Model
