摘要： A molten metal pump having an elongated shaft with an impeller disposed adjacent the end of the shaft and a means for rotating the shaft. The impeller is formed with an imperforate substantially circular base surrounded by a bearing and has a surface facing toward the shaft. At least two imperforate vanes are connected to and extend substantially perpendicular from the surface and radially from the shaft or a hub securing the shaft toward a peripheral portion of the base. The vanes are spaced apart at terminal inlet ends along their entire radial dimension to create an inlet area comprised of the axial opening between adjacent vanes at the terminal ends and an outlet area comprised of a radial opening between adjacent vanes along the axial direction of the vanes. Each vane has a leading edge with a distal portion adjacent the periphery of the base portion which forms an angle of less than about 100.degree. relative to a tangent to said circular base drawn at the center of the vane.

摘要： A molten metal pump includes an impeller disposed at the end of an elongate drive shaft. The drive shaft is disposed within an elongate, hollow post. The impeller and the end of the post are adapted to be immersed in molten metal. An inert gas is conveyed through the gap between the outer surface of the drive shaft and the inner surface of the post, which gas is discharged into the molten metal in the vicinity of the impeller. Because the drive shaft is insulated from the molten metal, it can be made of a durable material such as steel; because the post is stationary relative to the molten metal, the metal is stirred only by the impeller, and not by the drive shaft. The invention includes other features such as a quick disconnect capability and a radial adjustment capability.

摘要： A molten material pump includes an impeller housed within a base member of the pump. A plurality of grooves are defined in a peripheral sidewall of the impeller for either drawing a molten material into the base member's chamber or pushing molten material out of the base member's chamber. The impeller is rotated by a rotatable shaft connected to an upper surface of the impeller. The rotatable shaft includes a non-circular shaped lower end dimensioned to be received within a cooperating opening in the impeller. The molten material pump further includes a connecting assembly for interconnecting components of the molten material pump. The connecting assembly includes a first mounting member attached to a first pump component that is dimensioned to be fitted within a cooperating recess of a second mounting member attached to a second pump component. In another embodiment of the invention, a stub shaft connects an upper shaft portion of the shaft to the impeller. The stub shaft includes a universal joint that is not rigidly connected to the upper shaft portion. In addition, the universal shaft is configured to allow the stub shaft and impeller to pivot. A floating deflector block weighs on an upper sealing block of the pump for enhancing the seal at the pump's bearing surfaces.

摘要： Metal particles are melted by mixing them with molten metal contained in a bath. A shaft-supported, rotatable impeller is immersed into the molten metal and rotated so as to establish a vortex-like flow of molten metal. Metal particles are deposited onto the surface of the molten metal in the vicinity of the rotating impeller. The particles are submerged substantially immediately after being deposited onto the surface of the molten metal. The impeller includes a thin rectangular prism having sharp-edged corners and vanes that extend upwardly from the prism. The impeller also can be used to disperse gas into the molten metal by pumping the gas through a bore extending the length of the shaft and out of the impeller along the lower surface of the impeller. The gas is sheared into finely divided bubbles as it rises along the sides of the impeller.

摘要： Apparatus for injecting gas into molten metal includes a porous ceramic body having a first surface through which gas can be introduced into the body, and a second surface through which gas can flow from the body. A refractory member is attached to the body and surrounds at least the first surface, while leaving the second surface exposed. The refractory member is impervious to gas, while having a coefficient of thermal expansion approximating that of the body. Preferably, a refractory sealant securely attaches the refractory member to the body. By use of the present invention, the refractory member and the body remain tightly connected to each other at all times. Accordingly, gas leaks are prevented and all gas flowing into the body is discharged through the second surface, as desired.
