Feed pipe slurry enters, 2 clarifies liquid phase, 3 bowl, 4 slurry
enters the bowl directly, 5 screw conveyor, 6 solid phase settles
and pushes into the cone end, 7 solid phase outletSeparation
principle: Under the action of centrifugal force field, when the
density of the solid phase is greater than that of the liquid
phase, the solid phase is deposited on the inner wall of the bowl,
and the screw conveyor and the bowl move the solid phase to the
discharge under the set differential speed. When it enters the cone
end of the bowl and reaches the discharge port, it leaves the
overflow surface, the moisture content of the solid phase is
further reduced, and is discharged to the discharge port. The
liquid phase overflows from the overflow port at the big end of the
bowl.The overflow radius can be adjusted to suit different
materials. The smaller the overflow radius, the higher the moisture
content of the solid phase and the lower the solid content of the
liquid phase (the liquid phase is clearer); the larger the overflow
radius, the lower the moisture content of the solid phase and the
lower the solid content of the liquid phase. High (more turbid
liquid phase).LWX horizontal decanter (centripetal pump liquid)
centrifuge: the liquid discharge method is centripetal pump, and
the liquid discharge radius is adjustable. The outlet liquid has a
certain pressure and can be directly connected to the outlet
pipeline.LWXF horizontal decanter (explosion-proof) centrifuge:
Before starting the centrifuge, the centrifuge inner cavity and the
casing cavity are replaced with nitrogen, and the oxygen content
concentration in the inner cavity is below the set safe
concentration before it can be started. Nitrogen is added during
operation. Nitrogen seals are installed at both ends of the
centrifuge to ensure the isolation of the centrifuge cavity from
the outside and meet explosion-proof requirements. The motor of the
centrifuge and the electrical components on site must meet the
explosion-proof grade of the working condition. The transmission
belt is antistatic and has static grounding. In explosion-proof
applications, centripetal pumps are generally used. The solid
outlet of the centrifuge must be connected to the fan and other
devices.The settling velocity of the solid-liquid two-phase mixture
is determined by the dispersion state of the suspended matter and
the two-phase density, and is also significantly affected by the
surface state of the solid-liquid two-phase, because it can affect
the stability of the mixture and control the interaction between
particles. state of contact. The properties of these systems may
also be time dependent, as some suspensions have settling
velocities that vary with time.Settling velocity is the main basis
for type selection. By analyzing and testing the physical and
chemical properties of the solid-liquid mixture, determining the
separation process, and conducting necessary technical and economic
analysis (product quality, yield, energy consumption, production
capacity, operation safety, control), select the appropriate
separation equipment.Generally, the sedimentation method is more
economical than the filtration method, especially in those cases
involving high-volume, continuous liquid flow, gravity settling is
considered to be the first choice.When the density difference
between the solid-liquid two-phase is very small, try not to use
the sedimentation method for solid-liquid two-phase separation. Or
increase the density difference through appropriate process
methods, or increase its separation power through the action of
centrifugal force. Centrifuge system Centrifuge
