FIELD: machine building. ^ SUBSTANCE: centrifuge consists of centrifuging drum with permeable wall designed for loading treated products into it, of drive of drum rotation around vertical axis and of unloading facility with device for cleaning internal surface of permeable wall of drum. According to the invention devices for wall cleaning are made in form of a unit with at least two blades located inside the drum and arranged to rotate around vertical axis to travel from a retracted position, when the blade less opposes drum rotation, into contact position for cleaning the said permeable wall of the drum. Also blades can perform vertical progressive motions during unloading of products. The first and the second blades are arranged with a set off by height of the drum for cleaning the upper and lower parts of the drum correspondingly. Also the centrifuge additionally contains facilities of vertical progressive motion of the second blade with run limitation, facilities of vertical progressive motion of the first blade with run limitation and a facility of independent control of two blades. ^ EFFECT: design of centrifuge of cyclic operation facilitating improved distribution of force during cleaning operation and raising efficiency. ^ 6 cl, 3 dwg |
