An oil drilling cutting dryer belongs to the technical field of solid-liquid separation equipment and aims to solve the problem that conventional solid-liquid separation equipment is unreasonable in structural design, causes environmental pollution and wastes resources. The oil drilling cutting dryer adopts the structure that a conical screen cloth is fixed on a rotating arm, a central shaft is mounted in a shaft hole of the rotating arm, a scraping device is mounted on the central shaft, a transmission is fixed on a dryer housing, a motor is connected with the input shaft of the transmission, the transmission is connected with the rotating arm and the central shaft, baffles are connected to the interior of the housing of a dryer baseframe and divide the housing into a wet cavity, a dry cavity and a transmission cavity, a feed hopper is fixed at the top of the dryer housing, and a discharge hopper is fixed at the bottom of the dryer housing. The oil drilling cutting dryer has a simple structure, is suitable for solid-liquid separation and recovery of oil drilling cuttings, as well as solid-liquid separation in other applicable industries.
