Shield site muck screening treatment device and using method thereof

Abstract

The invention discloses a shield site muck screening treatment device and a using method thereof, and belongs to the technical field of shield muck treatment. The shield site muck screening treatment device comprises a feeding assembly, a multi-stage screening assembly, a concentration tank and a belt filter press, wherein the multi-stage screening assembly comprises a vibrating screen, a stirring wheel, a fine sand recycling machine and a coarse sand recycling machine, the vibrating screen comprises a screen body and a plurality of layers of screen faces, and screen holes are formed in the screen faces correspondingly. According to the shield site muck screening treatment device and the using method thereof, the feeding assembly is used for collecting muck on a shield site and conveying the muck to the multi-stage screening assembly, the muck is screened through multiple layers of screening faces to obtain rock blocks, then the muck sequentially pass through the stirring wheel, the fine sand recycling machine and the coarse sand recycling machine, then muck particles are classified and screened, finally, the muck is discharged into the concentration tank in the form of a sand-water mixture, and then precipitation separation is conducted, and mud is discharged to the belt filter press, and recyclable mud cakes are finally discharged through the filter press, so that the problem that muck is inconvenient to screen and treat on a shield site in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of shield tunneling dregs treatment, in particular to a screening and processing device for dregs on a shield tunneling site and a method for using the same. Background technique [0002] At present, major and medium-sized cities across the country are constantly constructing subways, and a large amount of subway muck, especially subway shield muck, is also produced. However, the high moisture content of the subway muck makes the muck show a certain flow state, which increases the difficulty of transporting the muck. Moreover, the existing slag and sewage can be recycled after certain treatment, but there is a lack of corresponding treatment devices at the shield tunneling site. Therefore, there is a problem in the prior art that it is inconvenient to screen the muck at the shield tunneling site. Contents of the invention [0003] The object of the present invention is to provide a screening and processi...
