Screening system for shield muck treatment

Abstract

The invention belongs to the technical field of shield muck treatment, particularly relates to a screening system for shield muck treatment, and solves the problems that a screening device is low in screening efficiency, poor in effect and high in sand and stone mud ratio in the prior art. The screening system comprises a vibrating screen (1) and a mounting frame (2), wherein the vibrating screen (1) is fixedly connected to the mounting frame (2); a feeding machine (3) is arranged at the feeding end of the vibrating screen (1); the vibrating screen (1) is provided with a high-pressure spraying pipeline (4) in a matched mode; and the high-pressure spraying pipeline (4) flushes each layer of screen. According to the screening system, the feeding machine is used for feeding materials to the vibrating screen, so that the amount of shield muck entering the vibrating screen is uniform, the muck is loose, the screening efficiency and the screening effect can be improved, and the high-pressure spraying pipeline flushes each layer of screen, so that the mud ratio of screened sand and stones can be further reduced. The screening system is suitable for screening treatment of the shield muck.

Description

technical field [0001] The invention belongs to the technical field of shield machine dregs treatment, and in particular relates to a screening system for shield machine dregs treatment. Background technique [0002] At present, the direct transport method is mostly adopted for the disposal of the muck generated in shield tunneling construction, but directly transporting the muck to landfill will pollute the environment, and a large amount of available resources in the muck will be wasted, so some construction sites use The method of vibrating sieving is adopted to classify and treat the muck. [0003] In the prior art, the muck excavated by the shield machine will be directly transported to the vibrating screening device by means of screw conveyor and belt conveyor. Due to the large mud content of the shield muck, the dregs are more likely to agglomerate. There are many, and the distribution of muck on the belt conveyor is uneven. If the muck is directly transported to the...
