УДОСКОНАЛЕННЯ КОНСТРУКЦІЇ ХОЛОДИЛЬНИКА КОЛОСНИКОВОГО З МЕТОЮ ПІДВИЩЕННЯ ЗНОСОСТІЙКОСТІ КОЛОСНИКІВ

Abstract

The article discusses one of the ways to improve the design of the grate refrigerator in order to increase the wear resistance of grate. Typically, the life of the grate is reduced when a certain amount of wear is exceeded, it is expressed in a decrease in the thickness of the elements and walls of the grate, which undergo oxidation and abrasion due to the movement of the cooled material. As a result, the grate ceases to function properly. In connection with that, there is proposed an improved grate design, in which: we have a contour of the bottom surface of the cavity in an inclined grate plate, made with an inclination growing in a direction opposite to the direction of movement of the cooled material. The grates are made with the ledges in an inclined plate of a triangular shape, also with reinforcing stiffening ribs of arched shape between the passages for cooling air. This will create a permanent protective layer of chilled material and will reduce the surface area of the grate while cooling the clinker in the grate refrigerator, which will increase the strength and lifespan of the grate and will accelerate the cooling of hot material.
