Title:
ACTIVE SORTING MUCK-COLLECTING DEVICE FOR SLURRY BALANCING SHIELD
Document Type and Number:
WIPO Patent Application WO/2021/042832
Kind Code:
A1
Abstract:
An active sorting muck-collecting device for a slurry balancing shield comprises a sorting stirring drum, a circulation pipeline (30), and a muck collection container (40). The sorting stirring drum comprises an external drum (10) and a rotatable grating drum (20) arranged coaxially. The grating drum (20) is provided with a rotating shaft (51), and is fixedly provided with a helical conveyance mechanism therein. The rotating shaft (51) is fixedly connected to the grating drum (20). The circulation pipeline (30) communicated with the grating drum (20) is correspondingly provided below the grating drum. The muck collection container (40) is fixedly provided below the circulation pipeline (30). The muck collection container (40) is communicated with the grating drum (20) at an opening end of a slurry discharge pipeline (32). The active sorting muck-collecting device for a slurry balancing shield has a compact structure, is easy to manufacture and install, and lowers the frequency of cleaning the muck collection container (40) by separate collection of large-sized and small-sized muck, thereby improving tunneling efficiency.
