Abstract
Abstract In a heat exchanger for cooling lumpy materials, there is provided a discharging means defined by a plurality of slotshaped holes formed in the bottom of the heat exchanger and located parallel to each other, and under which holes a perforated plate is installed for a reciprocating motion. A strip is mounted in each slot-shaped hole and along thereof, protruding beyond the lower edge of said hole and pushing the material being cooled to the holes in the perforated plate when the latter is in motion. This ensures uniform discharging of the heat exchanger over its entire cross-sectional area.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
149 words
A heat exchanger for cooling lumpy material, particularly ore cinders, comprising a housing having an upper portion and a bottom portion; tubular sections located horizontally one above the other in said housing and adapted for passing cooling water; adapters successively connecting said sections to each other; said heat exchanger housing having charging openings in its upper portion; said bottom portion being provided with slot-shaped holes parallel to each other and having their cross section shaped as trapeziums having their smaller base facing downwardly; a perforated plate reciprocably mounted underneath said bottom portion of the heat exchanger being capable of reciprocating motion in a direction perpendicular to the holes in the bottom portion; a strip installed along each hole in said bottom portion and protruding beyond the lower edge thereof and serving for directing the material being cooled to the holes in said perforated plate, when the latter is moving.
