Abstract: The invention involves a vibrating inclined plate box settlement separator, which is used for the liquid-solid separation, particularly applicable to high-efficiency settling concentration and separation of solid particles from liquid or water. The separator consists of an upper box and a lower tapered hopper. The upper box and the lower tapered hopper are connected securely to each other and sealed. The upper box is a rectangular or square steel-structured box with two supporting platforms on both of its sides, on which several spring assemblies are installed. The inclined plate box modules which can independently vibrate are installed on the spring assemblies. The feed box is placed on top of or inside the upper box. An overflow collect chute is welded on the side of the box frame opposite to the feed box.
