Abstract: In a metal melting and temperature-raising supply system, a melting apparatus heats a metal material that is in a solid state and changes the metal material to a molten metal that is in a liquid state. A temperature raising apparatus includes a heat-resistant container that houses the molten metal produced by the melting apparatus and a temperature-raising heating unit that heats the molten metal housed in the heat-resistant container. A molten metal supply apparatus provides the molten metal to an external processing equipment in a state in which a temperature of the molten metal heated by the temperature raising apparatus is maintained. A control apparatus controls an amount of metal material in the solid state changed to the molten metal by the melting apparatus and supplied to the heat-resistant container, based on an amount of molten metal supplied to the external processing equipment from the molten metal supply apparatus.

Abstract: A device includes an agitation tank, a liquid circulation means for circulating a liquid along a tank wall of the agitation tank, and at least one auxiliary heat transfer means provided inside the agitation tank, wherein the auxiliary heat transfer means is constantly put in a wetted state.

Abstract: With a liquid ejection apparatus where a liquid-transporting body is attached to an agitator shaft, the liquid-transporting body is revolved about the agitator shaft, with the rotational speed being changed in accordance with a change in liquid depth. Hence ejection liquid ejected from an upper opening of the liquid-transporting body over a large ejection distance and in sufficient volume, is distributed onto the inner surface of the tank and/or into the space above the liquid surface, thereby washing the inner surface of the tank, maintaining the heat transfer area, dispersing a foam layer on the liquid surface, and promoting evaporation of liquid in the tank.

Abstract: A liquid ejection apparatus has gutter bodies secured to an agitator shaft at predetermined inclination angles or gutter bodies or tubular bodies attached to these agitator shaft so that the size of the inclination angles are adjustable. The gutter bodies or tubular bodies of the liquid ejection apparatus are revolved around the agitator shaft so that liquid is ejected from the respective upper openings of the gutter bodies or tubular bodies. This liquid is distributed onto the inner surface of a tank, and/or into a space above a liquid surface, thereby washing the inner surface of the tank, maintaining the heat transfer area, and promoting evaporation of the liquid in the tank.

Abstract: An agitator blade comprises one or more cylindrical local agitators which have inner fabrics therein and are radially mounted on a mounting frame, which in turn is secured to an agitator shaft. The inner fabrics can include, for example, one or more twisted plates, one or more orifice plates, a plurality of bent plates, which are disposed in an alternately inverted relationship with one another so that the facing bent peripheral side of the adjacent bent plates cross each other, a plurality of flat plates or one or more net-like sheets. The agitator shaft is rotated by a motor to drive the local agitators to mix the fluid throughly. When applied for agitation and mixing processes, the agitator blade of this invention can realize a high degree of mixing easily and reliably in a short period of time and with a small driving power. Further, the construction of this agitator blade is simple.

Abstract: A thin-film evaporator comprises a substantially cylindrical heating wall, a rotating shaft disposed coaxially with respect to said heating wall, a reversible motor connected to said shaft for driving it in opposite directions, blade means on said rotating shaft for applying liquid to be evaporated to said heating wall to form a thin film thereon during rotation of said shaft in one direction and scraping means on said shaft for scraping possible scales off said heating wall during rotation of said shaft in the other direction.
