工作原理

Operating principle

刮刀下部卸料离心机为立式全自动过滤离心机。电机通过皮带驱动转鼓高速旋转，待分离的物料在预先编制的程序控制下，通过进料系统进入高速旋转的离心机转鼓内。在离心力场的作用下物料通过过滤介质 (滤布 /滤网)的过滤，液相经出液管排出机外，固相则被截留在转鼓内。物料检测装置实时检测物料充填位置，当转鼓内滤饼达到机器规定的装料量时停止进料。然后对滤饼进行洗涤、甩干。滤饼达到脱液要求后，离心机降低到刮料速度，刮刀装置在液 (气)动控制下将滤饼刮下并经离心机下部的出料口排出。

The automatic bottom discharge scraper centrifuge is vertical tuiiy-automatic filtrationcentrifuge. The motor drives the basket to rotate at high speed th rough the belt, andunder the control of pre-written program, the material to be separated is fed into thebasket through the feed system. After the material is filtered through the filtrationmedium (filfe r cloth/screen) under the action of centrifu g al force, the liquid phasedischarges out of the centrifuge through the liquid pipeline, and the solid phase isretained in the basket. A material detection device is used to detected material fillingposition in real-time manner and when the solid cake deposited in the basket reaches thespecified holding capacity of the centrifuge, feeding stops. Then wash and dry the solidcake. After the solid cake meets requirements for knock-out, the centrifuge reduces to thescraping rate, under the hydraulic (pneumatic) control, the scraper device removes thesolid cake, and then the cake id discharged at bottom outlet of the centrifuge.
