Centrifugal muck separation device

The utility model relates to the technical field of subway shield construction, in particular to a centrifugal muck separating device which comprises an outer cylinder and an inner cylinder, the outer cylinder is installed at the position of a muck outlet of a spiral conveyor, the inner cylinder is arranged in the outer cylinder and can rotate in the outer cylinder, and spiral fan blades are arranged in the inner cylinder. A gap serving as a water collecting tank is formed between the outer barrel and the inner barrel, a water draining hole is formed in the inner barrel, and a water outlet is formed in the outer barrel. The high-water-content muck conveying device has the advantages that normal conveying of high-water-content muck is achieved, and the problem that the muck is accumulated at an outlet of a screw conveyor due to the fact that the muck cannot be normally conveyed by a belt conveyor due to too high water content is solved; the device is simple and reasonable in structure, can be matched with the
