水力旋流器

模型HV-EXP4480

技术描述:

水力旋流器可用于分离悬浮在液体中的固体。在悬浮液中是在容器中配制的。搅拌器可防止固体颗粒过早沉降。偏心螺杆泵将悬浮液输送到旋风分离器的切向入口。在气旋中产生了一个向下的初级漩涡。向下的锥度导致漩涡反向。在中间它作为一个二次涡运动回到浸没管，在那里悬浮从气旋出现，失去了粗的材料在它。在旋风内部形成一个空气芯。离心力使初级涡旋中较粗的固体颗粒得到富集。它们在尖端喷嘴随底流排出。 It is mainly the fine material that is discharged from the top. The outflow form of the bottom flow changes depending on the solid concentration of the introduced suspension. Where the solid concentration is high, strand discharge occurs. Where the solid concentration is low, the discharge is fan-shaped. The flow rate in the inlet is adjusted by way of the pump speed and measured with a magneto-inductive flow meter. Sampling points are installed at the bottom and top flow points. The flow rates in them can be determined by means of a measuring cup and a stopwatch. To determine the solid concentration, a balance and a drying chamber are recommended. Using a suitable analysis device (such as a diffraction spectrometer), a separation function can be produced and the separation size determined. Quartz powder is recommended for use as the solid.
