APPARATUS FOR DEHYDRATING EXCAVATED EARTH AND SAND

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for dehydrating excavated earth and sand, in which the pressurizing force suitable for the throughput of the excavated earth and sand is exerted on the excavated earth and sand even when the throughput of the excavated earth and sand is fluctuated. SOLUTION: The apparatus 1 for dehydrating excavated earth and sand is composed of a dehydration mechanism 1a and a pressurization mechanism 1b. A pressurizing belt 32 constituting the pressurization mechanism 1b is composed of: an endless inner periphery-side belt main body 37 to be arranged on the inner peripheral side; a pressurizing body 38 arranged on the outside of the inner periphery-side belt main body; and an outer periphery-side belt main body 39 which is arranged on the outside of the pressurizing body and opposed to the inner periphery-side belt main body 37 in order to put the pressurizing body 38 between them. The pressurizing body 38 is formed by blowing air as a compressible fluid in the internal space of an endless bag 41 formed from a rubber-based material and arranging a plurality of partition walls 40 for partitioning the internal space in the internal space along the circulation direction of the pressurizing belt 32.
