The present invention is directed to a molten metal pump comprising an elongated pumping chamber tube with a base end and an open top end. A shaft extends into the tube and rotates an impeller therein, the impeller rotates proximate the base end. The tube has a diameter at least 1.1 times the diameter of the impeller. The pumping chamber tube preferably has a length at least three times the height of the impeller. The base end includes an inlet and the top end includes a tangential outlet. Rotation of the impeller draws molten metal into the pumping chamber and creates a rotating equilibrium vortex that rises up the walls of the pumping chamber. The rotating vortex adjacent the top end exists the device via the tangential outlet.

The present invention is directed to a molten metal pump comprising an elongated pumping chamber tube with a base end and an open top end. A shaft extends into the tube and rotates an impeller therein, the impeller rotates proximate the base end. The tube has a diameter at least 1.1 times the diameter of the impeller. The pumping chamber tube preferably has a length at least three times the height of the impeller. The base end includes an inlet and the top end includes a tangential outlet. Rotation of the impeller draws molten metal into the pumping chamber and creates a rotating equilibrium vortex that rises up the walls of the pumping chamber. The rotating vortex adjacent the top end exists the device cia the tangential outlet.

A molten metal pump includes an impeller, a pump base housing at least partially enclosing the impeller, a shaft connected to the impeller, a motor connected to the shaft, a motor mount plate for supporting the motor; and a post for connecting the motor mount plate to the pump base housing. The molten metal pump can include a connector that connects the post to the motor mount plate. The molten metal pump can include a socket for connecting the shaft to the motor. The shaft can comprise an assembly including an elongated metal rod having a first end and a second end and a metal non-circular drive member attached at the second end of the elongated metal rod. The impeller can include a cap member having a plurality of generally polygonally shaped inlet openings communicating with internal passages of the impeller, each inlet opening having an inner wall and an outer wall, the outer wall being longer than the inner wall, each inlet opening also including a leading wall and a trailing wall, the leading wall and the trailing wall each interconnecting the inner wall and the outer wall and each being inclined such that an uppermost edge of each wall precedes a lowermost edge of each wall in a first rotational direction.

Molten metal pump

A quick change conveyor roll assembly for metal or glass processing comprising an inner roll shaft having a rigid and elongated cylindrical surface supported and rotationally driven by an associate rotor mean. At least one removable spool having a cylindrical body with a first diameter, a hollow interior therethrough and a collar rigidly adapted at a first end, the collar having a second diameter whereby the second diameter is greater than the first diameter. At least one removable and replaceable insulated roll sleeve being slidably mounted over at least a portion of said removable spool and abutting said collar, the insulated roll sleeve including at least one layer of an insulation material and a securing means operably adjustable to hold said roll sleeve about said removable spool at a second end in a predetermined location on said inner roll shaft.

According to one embodiment, a molten metal impeller is provided. It includes a generally cylindrical graphite body having a plurality of passages extending from a top surface to a side wall. A hub is formed in the center of the graphite body. A ceramic cap member is secured to the top surface of the graphite body. The cap member is comprised of a ring forming a central passage shaped cooperatively to overlap the hub and a plurality of vanes extending radially from the ring to an outer rim. The rim has a height between adjacent vanes which increases in the direction of intended impeller rotation. The rim further has a height which decreases from its radially outer most edge to an inner most edge.

Molten metal impeller

A continuous galvanizing line uses a coating pot containing a molten zinc bath having bottom dross and further comprises a pump. The pump agitates the bottom dross so the bottom dross interacts with aluminum and converts to top dross, which can be removed without needing to stop the galvanizing line. A reaction vessel may also be used to provide a higher concentration of aluminum to react with the bottom dross.

Galvanizing bath apparatus

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.

Pump for molten materials with suspended solids

An apparatus for moving a stream of molten metal comprising a pumping member, a housing at least partially enclosing the pumping member, a power device seated on a support, and a shaft connecting the power device and the pumping member. At least one post is disposed between the support and the housing. The post includes an elongated rod comprising a metal alloy surrounded by an outer sheath. An inner member may surround the rod and provide a molten metal resistant barrier. The rod includes a first end connected to the support and a second end secured to the housing. A similar design for a shaft is also provided.

Shaft and post assemblies for molten metal apparatus

A self-contained water display. The water display includes a cylindrical fountain housing. The fountain housing contains at least one fountain nozzle extending vertically upwardly, and at least one pump adapted to supply water to the nozzle with sufficient volumetric throughput to cause a vertical water stream to be ejected therefrom. A vertically disposed transparent cylindrical cover surrounds the fountain housing with the fountain housing being located in a lower portion of the transparent cylindrical cover. The transparent cylindrical cover has a height above the nozzle that is at least as great as the height of the vertical water stream generated by the fountain nozzle. The fountain housing and the lower portion of the transparent cylindrical cover are surrounded by a lightweight shell simulating a rock. The water display may include a transparent aquarium surrounding the fountain housing and transparent cylindrical cover.
