    • A screen bowl centrifuge having first and second conically diverging screen sections. And a method of separating solids from liquid of a slurry includes feeding a slurry from a conveyor hub (14) to a cylindrical section (6) of a bowl (4)extending about the conveyor hub; scrolling the solids along the cylindrical section in a first direction and a majority of the liquid in a second direction opposite the first direction using at least one helical blade (16) extending from the conveyor hub; and sliding the solids from the cylindrical section along a conically diverging screen section of the bowl that includes a first conically diverging section (11) and a second conically diverging section(13), the first conically diverging section extending at a first angle (41) to the axis and the second conically diverging section extends at a second angle (43) to the axis, and the first angle is different from the second angle.

    • A screen bowl-type centrifugal machine that eliminates the problem of lowering of productivity caused by clogging by crystals at a screen portion, and in addition, where the amount of mesh leakage of processed objects at the screen portion can be reduced. Inside a hub (41) of a screw conveyor (40) is provided a cleaning liquid-receiving portion (43) for receiving a cleaning liquid for cleaning nozzles (45). Further, in the cleaning liquid-receiving portion (43) is provided a residual layer cleaning liquid-receiving portion (46) for receiving a cleaning liquid for cleaning a residual layer of processed objects at a screen portion (30). The residual layer cleaning liquid-receiving portion (46) is provided such that it is partitioned independently of the cleaning liquid-receiving portion (43). A cleaning liquid delivered to the residual layer-cleaning liquid-receiving portion (46) is directly jetted toward the residual layer of processed objects from the outer peripheral edge of a flight (42) with the residual layer-cleaning liquid-receiving portion (46) being partitioned from the cleaning liquid-receiving portion (43). The jetting is made by a cleaning route for a residual layer, which route is provided along a spiral direction of the flight (42).
    • 一种筛碗式离心机,其消除了由于屏幕部分处的晶体堵塞而导致的生产率降低的问题,此外,可以减少筛网部分处理物体的网眼泄漏量。 在螺旋输送机(40)的轮毂(41)的内侧设置有用于接收清洗喷嘴(45)的清洗液的清洗液接收部(43)。 此外,在清洗液接收部(43)中设置有残留层清洗液接收部(46),用于接收用于清洗屏幕部(30)的被处理物残留层的清洗液。 残留层清洗液接收部分46被设置为独立于清洗液接收部分43进行分隔。 输送到残留层清洗液接收部分(46)的清洁液体,从残留的层清洗液体接收部分(46)从飞行物(42)的外周边缘朝向被处理物体的残留层直接喷射 )与清洗液接收部(43)隔开。 喷射由用于残留层的清洁路线制成,该路线沿着飞行(42)的螺旋方向设置。

    • A centrifugal classifier that is reduced in size and capable of reliably and efficiently separating sediment and suspended matter from a raw liquid and capable of sufficiently washing separated substances, the classifier being also superior in drainage efficiency. Installed on the shaft barrel (30a) of a screw conveyor (30) are a plurality of plate vanes (33) extending axially and radially on the inner diameter side of a spiral vane (31). The outer end edge of each plate vane is positioned between the liquid level in a bowl (20) and the inner peripheral surface of the bowl, and the spiral vane is rotated along the outer end edges of the plate vanes. And the space between adjoining plate vanes on the inner diameter side of the spiral vane is a suspended matter conveyance passage (R). Further, the position close to a dam (24) in the inner peripheral surface of the bowl is tapered such that the diameter is gradually reduced toward the front. Further, a suspended matter drainage region (25) is tapered such that the diameter is gradually increased toward the suspended matter outlet (26) at the front end.
    • 一种离心分级机,其尺寸减小,能够可靠而有效地将原料液中的沉淀物和悬浮物质分离并能够充分洗涤分离的物质,分选机排水效率也优越。 安装在螺旋输送器(30)的轴筒(30a)上的是在螺旋叶片(31)的内径侧上轴向和径向延伸的多个板叶片(33)。 每个板叶片的外端边缘位于碗(20)中的液面和碗的内周表面之间,并且螺旋叶片沿着叶片的外端边缘旋转。 并且螺旋叶片的内径侧的相邻板状叶片之间的空间是悬浮物质输送路径(R)。 此外,靠近碗的内周面中的坝(24)的位置是锥形的,使得直径朝向前方逐渐减小。 此外,悬浮物排出区域(25)是锥形的,使得直径在前端朝着悬浮物质出口(26)逐渐增加。
