Abstract

The object of the invention is a mechanical rotary casting sand reclaimer, having a base with a grain hole and a lock, wherein the base contains a rotor supported by a vertical bearing, coupled with a driving motor by means of a belt transmission, and an abrasive ring installed on the base and enclosed within a cylindrical casing oriented concentrically to the rotor. The reclamation unit comprises an abrasive ring (5) with a profiled internal surface and a cylindrical external surface with lugs on its perimeter and on the bottom of the ring located within the cylindrical casing (4). It further comprises a rotor supported by a vertical bearing, the rotor having abrasive blades or rods (6) and located in the base concentrically to the abrasive ring (5). The rotor is connected with a driving motor (7) by means of the belt transmission. It further comprises a ring air blade (9) installed on the top surface of the abrasive ring (5), the ring air blade having a dedusting chamber casing (10) attached to it. The casing (10) is equipped with a casting sand batch hole (11) and a side revision window (12). On the top surface of the abrasive ring (5) there is further installed, coaxially with the axis of the chamber, a telescopic dedusting duct (14) ending (13), the dedusting duct (14) being connected with a dedusting cyclone (17) and a suction fan (18). The dedusting duct (14) has sensors (15) for measuring air velocity and a triboelectric dust counter; the sensors (15) being connected with a triboelectric sensor signal converter (16) and a controller of the rotational speed of the driving motor (7).
