Settling basin of tailing recovery device

The utility model discloses a settling tank of a tailing recovery device, which is arranged in a conical shape, a porous filtering partition plate is arranged on the inclined surface of the settling tank according to the grain size of sand, a channel for muddy water to pass through is reserved between the porous filtering partition plate and the inclined surface of the settling tank, and a sand settling plate is arranged at the bottom of the porous filtering partition plate. Water inlet pipes and material pumping pipes are arranged at the bottoms of the porous filtering partition plate and the sedimentation tank. The sand and water mixture concentration can be increased and freely adjusted, sand and sand pre-separation is achieved, the proportion of sand and gravel in mortar is increased, and the later-period tailing recovery effect is guaranteed. 本实用新型公开了一种尾砂回收装置沉降池，沉降池呈锥形设置，在沉降池斜面上根据砂石粒径设置有多孔过滤隔板，多孔过滤隔板与沉降池斜面留有供泥水通过的通道，多孔过滤隔板底部设置有砂石沉淀板，多孔过滤隔板底部和沉降池底部均设置有进水管和抽料管。本实用新型可以增加并且自由调节砂水混合物浓度，实现泥沙预分离，提升砂浆中砂石比例，保证后期尾
