Centrifuge, removing fluid efficiently from substances with small solid content, minimising stress etc. - has three rotors with 1st rotor, turning at same speed as closing unit and 2nd rotor turning at same speed as 3rd rotor having apertures leading to cells on 2nd rotor

摘要

The centrifuge has a centrally symmetric rotor (100) consisting of two coaxial sections (10,20) turning in the same direction at different speeds. The first rotor (10) consists of a cylindrical case with an outlet (12) surrounded by a closing unit (40) incorporating a drainage window (42) and rotating at the same speed. Between the first rotor section (10) and the closing unit (40) formed as a cylindrical case by the second rotor (20), is a wheel incorporating cells (22) which ejects fluid of specific weight from the centrifuge chamber (50) outlets (12) through the drainage window (42). The novelty is that the rotor (10) turns at the same speed as the closing unit (40) and is arranged between the rotor chamber and the drainage window (42) and thus prevents the immediate egress of the centrifuged product from the chamber; further that a third rotor (30) turns at the same speed as the second (20) and that the third rotor (30) has apertures leading to the cells (22) on the second rotor (20). USE/ADVANTAGE - The assembly separates substances of different specific weights. The assembly removes fluid efficiently from substances with minimum solid content and minimises physical stress and damage to the product in continual operation.
