GKH Series Horizontal Siphon Scraper Discharge Centrifuge is a kind of filtering centrifuge with automatic control, continuous operation and intermittent discharging, which can complete the processes of backwash, feeding, desludging, washing, dumping and discharging at full speed or variable speed, and it is suitable for separating the crystalline or short-fibre materials with the particle size (diameter) of 5μm~5mm and the concentration of suspending liquid (solid-phase volumetric ratio) of 1%~40%, and it is especially suitable for the occasions of large-load production and the need of full washing. It is especially suitable for large-load production and occasions requiring sufficient washing.
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).
