摘要： A torque coupling system includes an impeller (13) that is connected to one end (26) of an impeller shaft (15) without the use of threads. The connection is made by cement and dowels (38). A drive system for the shaft (15) includes a hollow coupling (42) into which the other end (24) of the shaft (15) can be fitted. The shaft (15) includes longitudinally extending slots (40) formed at its end (24). The coupling (42) includes spaced, longitudinally extending keys (44) adapted to be fitted into the slots (40) formed in the shaft (15). The drive system also includes a torque limiter (60) that is connected intermediate the coupling (42) and a drive motor (16). If the drive motor (16) is an electric motor, the motor (16) can be provided with automatic shut-down circuitry that is activated in the event of a current/torque overload. Visual and aural alarms are provided to alert the user that a shut-down has occurred.

摘要： An impeller (1) for a molten metal pump having a cylindrical body comprised of a refractory material. The cylindrical body includes generally coplanar top (2) and bottom (12) surfaces. A central bore (4) is provided in the top surface (2) to provide a point for mating with a shaft. A plurality of circumferentially spaced passages (6) extend from the top surface (2) to a side wall (8) of the impeller (1), each of the passages being separate and preferably having an inlet opening (5) which is equal to or less than the corresponding outlet opening (9) in size.

摘要： In a charge well (C) for adding scrap metal pieces or particles to a molten metal bath, a stationary diverter (20) is provided in the charge well (C) for diverting the circular flow of molten metal, caused by orientation of the inlet port (14), in a downward direction, thereby creating a downward flow of molten metal which results in quick and efficient submergence of incoming lightweight scrap metal pieces or particles. Preferably, the diverter (20) includes a leading edge (22) which extends in a generally radial direction within the charge well (C) and a flat top (24) which tapers from the leading edge (22) to a point or narrowed trailing edge. A downward curver surface (28) extends from the leading edge (22) to facilitate the downward flow of molten metal.

摘要： A coupling mechanism for a molten metal processing system includes an elongated shaft having an upper axial end and a lower axial end. A passage having a torque facilitating shape extends through at least a portion of the shaft. The upper end of the shaft tapers inwardly and forms a tapered seat. At least one channel is machined into an outer surface of the upper end of the shaft. The channel has a first portion extending longitudinally downward from a top surface of the shaft and a second portion extending from the first portion at an angle greater than 90° relative to the first portion. A coupling member, for coupling the shaft to a drive system forming a bayonet coupling. The cavity of the coupling member tapers outwardly forming a mouth which engages the tapered seat of the shaft in a sealing relationship.
