Document Type and Number:
WIPO Patent Application WO/2024/036669
Kind Code:
A1
Abstract:
A water coal slurry concentration device, which belongs to the technical field of water coal slurry preparation apparatuses. The device comprises a grinding housing (1), wherein a grinding mechanism is connected inside the grinding housing (1); a filter unit is connected below the grinding housing (1), and arranged corresponding to a discharge port of the grinding mechanism; a pulverized-coal particle size distribution mechanism is correspondingly arranged below the filter unit, and is configured to separate pulverized coal having different particle sizes; an output end of the pulverized-coal particle size distribution mechanism communicates with a stirrer, which is configured to stir the pulverized coal having different particle sizes into a water coal slurry; and the grinding mechanism comprises a first support (2) which is fixedly connected to an inner side wall of the grinding housing (1), and a step-by-step grinding unit, a first adjustment unit and two second adjustment units are connected to the first support (2), the first adjustment unit being configured to synchronously adjust grinding gaps of the step-by-step grinding unit, and the two second adjustment units being configured to unify the grinding gaps of the step-by-step grinding unit.
