The tubular-bowl centrifuge of the present invention is by slide bearing assembly, drum assembly, catch tray component, nose assembly, machine
Body etc. is constituted.Power is transmitted to belt pulley and main shaft on head by belt, pinch roller by motor, so as to drive rotary drum around certainly
Body axis is rotated at a high speed, and powerful centrifugal force field is formed in drum inner wall.Material is in bottom feed mouthful injection rotary drum, powerful
Centrifugal action under, force feed liquid carry out hierarchical motion.The liquid of light weight flow to rotary drum top and passed through at rotary drum center
Catch tray is reclaimed；The solid of quality weight is got rid of on drum inner wall, and manual cleaning to be shut down, what liquid was then held with slave goes out liquid
Mouth is flowed continually out.
The disk centrifugal electric motor of the present invention drives and rotated at a high speed.There is one group of dish being nested together mutually in rotary drum
Shape part -- disk.The gap of very little is left between disk and disk.Suspension (or emulsion) is by entering positioned at rotary drum center
Expects pipe adds rotary drum.When suspension (or emulsion) flows through the gap between disk, solid particle (or drop) is in centrifuge
It is deposited under effect on disk and forms sediment (or liquid layer).Sediment slides along disc surface and departs from disk and accumulate in rotary drum
The maximum position of diameter, the liquid after separation discharges rotary drum from liquid outlet.The effect of disk is to shorten solid particle (or drop)
Settling height, expand the settling area of rotary drum, substantially increase the production energy of seperator due to being mounted with disk in rotary drum
Power.The solid in rotary drum is accumulated in take rotary drum apart after seperator shutdown and do not shutting down by manually removing, or by slagging device
In the case of from rotary drum discharge.The electrolyte of the present invention may be considered suspension.
