Patent ID: 8580008

Claim:
A vertical filtering and separating apparatus for purifying pollutants in a machine which generates machine chips, oil, steam, mist or smoke, comprising: an air inlet suction pipe having a first section connected to a machine to be purified, and a filter cabin that is transversely crossed by a mesh, for coarse filtering of air sucked through the inlet pipe, said air inlet suction pipe having a second section which extends down from said filter cabin and enters a central part of a separating system containing a cylindrical outer casing, a cylindrical rotor and a rotor bottom, said air inlet suction pipe extending down near to the rotor bottom; said cylindrical rotor having a curved face with vertical parallel shaped openings, inner paddles at angles tilted a few degrees from the vertical axis, outer paddles at angles tilted a few degrees from the vertical axis with longitudinal folds of about 130° forming gutters in the direction of rotation, and holes leading to a drainage surface, the cylindrical rotor having an upper face with a central circular opening through which the air inlet suction pipe passes, said upper face also having a set of external horizontal rectangular paddles, the cylindrical rotor being connected by a shaft to an electrical motor located under the separating system; said cylindrical outer casing having an upper lace through which the air inlet suction pipe enters, the cylindrical outer casing having a set of holes in its curved face located under the rotor but above the motor and leading to a drainage pipe, plus a second set of elongated holes located higher on said curved face which also lead to a drainage pipe, the cylindrical outer casing having a set of filters placed under said upper face for fine filtration of air, composed of an inner filter and an outer filter; and an alarm system connected to a pressure switch with a sensor that detects an increase in air pressure.
