Disc centrifuge is a kind of vertical centrifuge. The drum is installed on the upper end of the vertical shaft, which is driven
by the motor through the transmission device. There is a set of disc-shaped parts in the drum, which are overlapped with
each other. There is a small gap between discs. The suspension (or emulsion) is added to the drum through the feed pipe in
the center of the drum. When the suspension (or emulsion) flows through the gap between the discs, the solid particles (or droplets) settle on the discs under the action of centrifuge to form sediment (or liquid layer).
The sediment slides along the surface of the disc and gets away from the disc and accumulates in the part with the largest
diameter in the drum. The separated liquid is discharged from the outlet of the drum. The function of disc is to shorten the
settling distance of solid particles (or droplets) and expand the settling area of the drum. The production capacity of the
separator is greatly improved due to the installation of disc in the drum.
It can realize liquid-solid separation. This machine has better separation. It can be operated manually or automatically or remotely with PLC control to timer the process of working and solid discharge to save lots of labour work. It is simple in structure and easy in maintenance.
Main Purposes: This machine is widely used for many industries, such as dairy, beverage, pharmacy, chemicals, petrol, metallurgy and biology, etc.
Structure and Principle:
The bowl rotates at a high speed round the main axis, driven by a motor through hydraulic coupling and screw gear pair. stock liquid flows from the upper feeding pipe into the bowl's bottom and then will be separated through holes of disc seat. by the action of centrifugal force field, heavy liquid flows along the inner wall of discs to the inner wall of the bowl, after up flowing along them, it will be discharged by the heavy liquid pump, the light liquid will be done by the light liquid pump, which flows along the inner wall of discs into centre pipe and then up to high liquid outlet. the larger solid phase particles left will sedimentate on the bowl's wall and then will be discharged through nozzle out of the sediment outlet.
