The operation of the centrifugal extractor is as follows:
A motor is connected to the mains supply, the shaft of which drives the rotor. After the rotor has set a predetermined number of revolutions, the initial processed solution through the nozzle - 20, and the extractant through the nozzle - 21 is fed into the mixing chamber - 18, where they are mixed with an agitator - 14 mounted on the rotor shaft - 12. The ribs 19 located in the chamber 18 prevent the twisting of liquids in the process of mixing. The resulting emulsion is transported by the blade conveyor 13 to the rotor 5. Under the action of centrifugal force in the rotor housing 6, the emulsion is stratified into light and heavy phases, while the ribs 9 assembled with a reflective disk prevent the emulsion from twisting inside the rotor. The light phase moves upward in the central part of the rotor while the heavy phase discarded by centrifugal force moves upward along the inner wall of the rotor. The light phase reaches the level of the nozzles 8, adjusted along the boundary of the separation of phases, and since the inlet openings of the nozzles are in the zone of movement of the light phase in the central zone of the rotor, the latter, overflowing into the nozzles, is removed from the rotor into the chamber 17, from where it is removed from the centrifugal nozzle 22 extractor. At the same time, the heavy phase, moving along the inner wall of the rotor, reaches the membrane 4 and through the holes in it enters the cavity of the hydraulic lock. The heavy phase moves to the hydraulic lock overflow and then, passing through the radial holes of the hydraulic lock, enters the chamber for the heavy phase 16 from where it is removed from the extractor through the pipe 23. Samplers 24 with shutoff valves 25, structurally combined to increase the rigidity of the assembly with nozzles 22 and 23, serve to control the quality of the extractor without stopping the separation process. The labyrinth seal formed by the water trap and the extractor cover prevents the entry of liquid, droplet-like and vapor medium into the extra-extractor space.
The length of the output tubes of the light phase 7 determines the position of the phase interface in the rotor, while the design allows you to refine the length of the tubes using screw adjusting nozzles 8 to configure the extractor for various density technological systems.
