  • Active sorting muck-collecting device for slurry balancing shield
    Patent number: 11484912
    Abstract: The present application discloses an active sorting muck-collecting device for slurry balancing shield, aiming at solving a technical problem that an existing muck-collecting device cannot provide reliable sorting function for a shield slurry circulation system. The device includes a sorting stirring cylinder, a circulation pipeline and a muck-collecting box, the sorting stirring cylinder includes an outer cylinder and a rotatable grid cylinder coaxially-configured. The grid cylinder is configured with a rotating shaft, and a spiral conveying mechanism is fixedly configured inside. The rotating shaft is fixedly connected with the grid cylinder. A circulation pipeline communicated with the grid cylinder is correspondingly configured below the grid cylinder. A muck-collecting box is fixedly configured below the circulation pipeline, and the muck-collecting box is communicated with the grid cylinder at where an output end of a slurry discharging pipeline locates.
