Description

Technical Field

[0001] The utility model relates to the field of mud treatment, in particular to a mud treatment device for a mud-water balance shield machine. Background Art

[0002] The mud slag discharge of the slurry shield machine is completely dependent on the circulation of the mud. During the shield tunneling process in sandy gravel formations, round gravel formations, strongly weathered rock formations, fault fracture zones, and calcareous mudstone, siltstone and other formations, a large number of pebbles or broken rocks with a particle size of 20mm-250mm will be produced on the shield face under the cutting of the shield cutter head. The maximum particle size of the material allowed to pass through the slurry pump (p2.1 pump) of the general slurry shield machine is 160mm-200mm. These large-size particles may block the slurry circulation pipeline or damage the blades of the slurry pump when entering the slurry tank, slurry circulation pipeline, and slurry pump.

[0003] Chinese patent number CN202221327035.2 discloses a mud processing device for a slurry balance shield machine, including a first crushing component, a second crushing component, a feed pipeline and a discharge pipeline. The first crushing component includes a jaw crushing mechanism, and the second crushing component includes a toothed roller crushing mechanism. The feed port of the jaw crushing mechanism is connected to the feed pipeline, the discharge port of the jaw crushing mechanism is connected to the feed end of the toothed roller crushing mechanism, and the discharge end of the toothed roller crushing mechanism is connected to the discharge pipeline.

[0004] From the above, it can be seen that the mud processing device can be set at the bottom of the air cushion bin of the slurry balance shield machine to further improve the crushing effect and prevent long pebbles and large-size pebbles from entering the next-level processing equipment. However, this case still has the following shortcomings: the crushed stone is further crushed by the crushing mechanism, but the crushing of the crushed stone is uncontrolled, resulting in the crushed stone being of different sizes. When such crushed stone and mud are transported uniformly, it is very easy to cause damage to the spiral feeding piece of the mud conveying device.

[0005] Therefore, in order to solve the above problems, a slurry processing device for a slurry balance shield machine is proposed. Utility Model Content
