1400×1400毫米倾斜浓密箱是一种高效浓缩设备。笔者在做郴州矿冶厂尾矿水净化和锰矿细泥回收工业试验中,采用了这种设备,并在原定型设备结构的基础上作局部改进,使其具有过滤和浓缩的双重作用。具体作法如下。(一)将原上层朝一个方向倾斜55°角的倾斜板(见图a),改为上中两层分别朝两个相反方向倾斜55°角的倾斜板(见图b)。这样能增加上升矿泥微粒(群)与倾斜板碰撞的机会,有利于矿泥沉淀。(二)在图b的基础上,将上层倾斜板取消,用过滤介质代替(见图c),本试验采用卵石和焦 The 1400 × 1400 mm sloping thickener is an efficient concentrator. The author is doing Chenzhou mine tailings purification and manganese ore fine sludge recycling industrial test, the use of such equipment, and the original stereotypes in the structure of equipment for local improvements, so that it has the dual role of filtration and concentration. Specific practices are as follows. (A) Change the incline plate inclined 55 ° to one direction from the upper deck (see Figure a) to the incline plate (Figure b) inclined by 55 ° in two opposite directions respectively. This will increase the chances of increasing the collision of the slime particles (slabs) with the sloping plate, which is favorable for the sludge settling. (B) On the basis of Figure b, remove the upper inclined plate and replace it with filter media (see Figure c). The test uses pebbles and coke
