Abstract

FIELD: metallurgy, in particular, equipment for processing of metal wastes, including those contaminated with organic substances, chips, powders separated from grinding wastes, metal containing sludges. SUBSTANCE: apparatus has vertical housing formed as pipe with open upper and lower bases and embraced with heater. Upper and lower bases of vertical housing are covered with upper and lower layers of granular inert material, respectively. Lower base is provided with grate and gate for retaining of lower layer of inert material. Vertical housing is mounted within auxiliary container, which is provided with sand seal overlapping lower base of housing and hole with gate for removal of sand and liquid metal. Grid has center plate, which covers hole. Upper layer is formed as dispersion valve with body deepened into sand seal and is composed of detachable parts, which may be inserted into housing, such as ring suspended below upper base of vertical housing and flanged branch pipe mounted on ring so that space is defined between ring and housing. Space is filled with sand. Heater is of inductor-type. Vertical housing is made conical, with top base having larger diameter. EFFECT: increased efficiency, wider operational capabilities, simplified construction and enhanced reliability.

Claims (1)

The invention relates to techniques for processing metal waste, including shavings contaminated with organic substances, powders isolated from grinding waste, metallurgical slag. The purpose of the invention: improving the efficiency of deeper processing of metal waste, namely processing to the final product in the form of metal ingots. New in the device is that the vertical casing is placed in an additional enclosing container with a sand shutter on the lower base, overlapping the lower base of the vertical housing, and a tap hole with a shutter for removing sand and liquid metal, while the grill is equipped with a thrust plate in its center, overlapping notch, and the upper layer is made in the form of a dispersion valve with a housing immersed in a sand valve assembled from detachable parts inserted into the housing, namely a ring suspended under the upper base of a vertical ceiling elements casing pipe flange mounted on this ring, to form a gap between it and the casing filled with sand. In addition, the heater is made in the form of an inductor, and the vertical body is made under a cone with an upper large base. The invention may find application in metallurgy.
