Abstract
A screen settlement coal slurry centrifugal dehydrator relates to a centrifugal device separating the fine grain from the water in the coal slurry and includes a material inlet pipe, a transmission belt wheel, a bearing, and a roller and so on. The cylindrical roller with the screen of the centrifugal dehydrator and the hollow shaft spiral rotator form high-speed differential speed rotation. The planetary gear box implements the differential speed operation. After the coal slurry flows into the coal slurry material tank through the material pipe, the coal slurry is distributed to the seam between the hollow shaft spiral rotator and the cylindrical roller with the screen. As a gap exists between the hollow shaft rotator and the cylindrical roller with the screen, the material is pushed forwards along the rotation of the hollow shaft spiral rotator. When the material flows into the roller screen section, by the action of the centrifugal force and the differential speed, the water is quickly thrown out of the roller and the left coal slurry cake-material is pushed into the coal slurry cake-material bin by the spiral rotator to make the fine grain products in the coal slurry is effectively recovered and the disposal quantity is large and the structure is simple.
