The machine is solid-liquid separation equipment which adopts
continuous operation and intermittent discharging. It is controlled
by PLC.It regulates speed by frequency convertor, braking system
adopts dynamic braking and regenerative braking. Through such
procedures as product level detection, speed, inspection, shaft
temperature and vibration monitoring, the whole separation process
is automatic circulative work(including feeding, dehydration,
washing, discharging and etc.) Also manual operation mode is
available which can be changed over from full-automation mode by
customer's will.
WORKING PRINCIPLE
▷When predetermined target is met and drum speed is suitable for
feeding, feeding valve will be open automatically and product level
detection begins to work.▷When layer thickness is thick enough to reach the product
detection slab, feeding valve closes to stop feeding.
▷Under the effect of centrifugal force, most of the liquid in
suspension is thrown out through filter cloth and then flows into
mother liquid tank through horizontal liquid outlet.
▷With product dehydration going on, centrifuge will automatically
slow down to washing speed according to technical requirement for
washing.
▷Washing valve opens automatically. With washing liquid rising to a
certain height, washing valve closes and centrifuge speeds up
automatically for further dehydration(secondary filter).
▷After operation, product will be fully dried. Then discharging
valve opens and discharging cylinder begins to work when
centrifuge automatically slows down to predetermined speed.
▷With scraper rising spirally and automatically,solid product is
scraped down into the hopper equipped with spiral discharger: With
constant motion of spiral discharger, product is pushed out and
discharged through valve.▷Scraper rises closer to filter cloth with a certain distance till
the bar on scraper device approaches proximity switch to stop
scraper rising then retreats quickly after a short stay(about
15s)then enters next cycle.
MAIN CHARACTERISTICS♦ It is fully conformed to GMP CGMP and meet the requirements of
asepsis raw medicine production.
♦ With absolute isolation between power area and process area.It is
suitable for occasion when customer requires high quality cleaning
to avoid the contamination to product.
♦ The out shell bucket can be opened, so the whole internal parts
can be observed and easy for touch wiping and cleaning.
♦ Perfect CIP system can be carried out to wash the internal parts
of centrifuge to avoid cross contamination which are not easy to
clean.
♦ Unique pneumatic counter-pulse device is equipped, which can
remove remnant filter cake as much as possible.
♦ Totally-enclosed structure equipped with inert gas protection is
adopted to be used in ex-proof 1 section.♦ The automatic residual cakes removing device is optional (have
owned the national patent).
