LWL卧式螺旋卸料过滤离心机
LWLHorizontal Screw Unloading Centrifuge Filtration
■ 工作原理How To Work
悬浮液从进料管进入螺旋内腔，并通过螺旋小头接近锥端底部的喷料口进入转鼓，在离心力场作用下料浆中的液相通过设置在转壁上的筛网被分离出去，固相颗粒则被截留在转鼓内；同时，转鼓内的固相颗粒在离心力和螺旋与转鼓之间的差速作用下从转鼓小端向转鼓大端运动，在此运动过程中，由于回转直径的加大，离心力得到快速递增，固相从初始进入时的高含湿量固相到排出转鼓时达到低含湿量固相，从而实现固液相自动、连续的分离。
LWL卧式螺旋卸料过滤式离心机是一种能耗低、性能稳定、分离效果好的机型。广泛应用于化工、食品、盐、采矿、制药等行业。分离过程中的进料、脱水、洗涤、卸料等工序连续完成，生产效率和自动化程度高，是一种先进的分离设备。
但因其分离原理和结构特性，其对物料的针对性也较强，在选型时应进行物料分析和相应的试验，以确定其适用和分离性能。
The feed liquid / slurry is introduced to the centrifuge through a feed tube and into the feed distribution chamber, and is jetted into the drum through the hole near the cone point of the scroll. Under centrifugal force the solids separate from the liquid and settle against the bowl wall, while the clarified liquid exits over the overflow screen. The solids in the conical drum are conveyed up from the smaller end to the bigger end while the scroll turns at a slightly different speed. The bigger diameter is, the bigger centrifugal force produces to separate the liquid/solids.
The solids are dried when they are drained out the drum.
LWL horizontal scroll centrifuge is the one with low energy consumption, stable performance and good separating effectiveness. It is widely applied to chemical, foodstuffs, salts, mining and pharmacy industries. The separation processing from feeding to dewatering, cleaning and discharging is continuous with high processing efficiency and degree of automation. It is the advanced separation equipment.
Given the working principle and its structure, this model of centrifuges is not applied to all materials. So it needs to test and analyze the materials before selecting this model.
