Horizontal spiral discharge sedimentation centrifuge (referred to as horizontal spiral centrifuge ) is the separation of suspension using the principle of centrifugal sedimentation. It can be used for various suspensions with solid phase particles greater than equal to 3um liquid-solid density difference greater than equal to 0.05g/cm3. Solid-liquid separation. This series of centrifuges are divided into cocurrent, countercurrent, compound spiral, bidirectional extrusion other forms on the rotor structure. In use, there are models for concentration, dehydration, integrated dehydration, three-phase separation, classification, clarification, etc., so they can be widely used Adapt to different material separation requirements, its characteristics are: continuous feed, continuous discharge, high speed, high length-to-diameter ratio, the solid phase is more dry after separation, the liquid phase is clearer.
After the rotating body composed of the rotating drum the spiral body reaches the rated rotational speeds n1 n2, the suspension continuously enters the spiral body accelerating hopper through the feed pipe for acceleration. Due to the centrifugal force , the materials are evenly distributed in the inner cavity of the rotating drum, the specific gravity The material is attached to the drum wall (outer layer), the smaller the specific gravity, the more the material will gather in the middle (inner layer), forming a two-phase multi-phase stratification. At this time, after the pushing effect of the spiral blade, the solid The pre-drying zone is pushed to the solid phase outlet discharged out of the machine, while the liquid phase is discharged the liquid phase outlet through the overflow hole.
