Shield tunneling machine slurry separation equipment with porous rubber conveying belt type slurry separator

Abstract

The invention provides shield tunneling machine slurry separation equipment with a porous rubber conveying belt type slurry separator and a method. The shield tunneling machine slurry separation equipment is characterized in that slurry discharged from a shield tunneling machine enters a porous rubber conveying belt type separator 201 after being decompressed by a decompression box 202; and afterslurry is separated by the separator 201, coarse particle materials are conveyed into a slag field to be stacked, and small particle materials enter a slurry storage tank A 213 through meshes of a rubber conveying belt. The equipment and the method provided by the invention have the advantages that a conveying chain 302 is positioned outside a material blocking pore plate 303, so that the fault that stones in materials are clamped into the chain is avoided; the rubber belt runs stably and has no noise; the problem that a scraper of a traditional metal scraper conveyor is frequently jacked up by materials, so that the working efficiency is reduced is solved; and for materials which are difficult to separate and dehydrate, a flushing device and / or a vibrating device can also be additionallyarranged.

Description

technical field [0001] The invention relates to shield machine mud separation equipment and a method with a perforated rubber conveyor belt type mud water separator, belonging to the field of mud water treatment. Background technique [0002] In the traditional muddy water treatment process, such as figure 1 As shown, the mixed mud of muck, sand and stone discharged from the shield machine is decompressed through the decompression box 102, and then enters the coarse screen 101 for screening and dehydration, and the oversize material with larger particle size is sent to the slag yard for stacking; The small material enters the A slurry storage tank 113 and the B slurry storage tank 112 connected with it through the screen, and is pumped into the primary cyclone 104 by the 1# slurry pump 111, and the overflow of the primary cyclone 104 is fine. The particle slurry enters the C slurry storage tank 110 for secondary separation, returns to the B slurry storage tank 112 for recir...

AI Technical Summary

Problems solved by technology

[0003] The inventor found in engineering practice that the coarse sieve 101 of the above-mentioned traditional technology is a double-layer vibrating screen with a metal screen, which is bulky, expensive, and noisy in operation, and stones are easy to get stuck in the gaps of the metal screen bars. difficulty

Especially for those engineering cases that only dehydrate the mud of the shield machine and then discharge it, and do not need to recycle sand and gravel, it also exposes the shortcomings of supporting equipment with excessive functions, high operating costs, and complicated operation and maintenance.
