Centrifuge Decanter

BWT卧螺离心脱水机主要由转毂和带空心转轴的螺旋输送器组成，污泥由空心转轴送入离心脱水机转筒后，在高速旋转产生的离心力作用下，立即被甩人转毂腔内。污泥颗粒比重较大，因而产生的离心力也较大，被甩贴在转毂内壁上，形成固体层；水密度小，离心力也小，只在固体层内侧产生液体层。固体层的污泥在螺旋输送器的缓慢推动下，被输送到转载的锥端，经转毂周围的出口连续排出，液体则由堰四溢流排至转毂外，汇集后排出脱水机。

BWT Decanter Centrifuge mainly by sedimentation and reproduced with the hollow shaft of the screw conveyor formed by the hollow shaft into the sludge dewatering machine drum, in high-speed rotation of the centrifugal force, were immediately transferred hub cavity left behind inside. A larger proportion of the sludge particles, the resulting centrifugal force is also large, been left attached to the switch hub wall, the formation of the solid layer; water density, centrifugal force is also small, resulting only in the solid layer inside the liquid layer. Solid layer of sludge in the screw conveyor driven by the slow, was transported to the end cone reprinted, reproduced by the continuous discharge of the export around the liquid discharge from the overflow weir to four reproduced, the collection discharge after the dryer.
