DEVICE FOR LOOSE MATERIAL COOLING Russian patent published in 2011 - IPC C10B39/00 F27B7/38 

FIELD: machine building.

SUBSTANCE: device for loose material cooling consists of water bath 1 with rotary drum 2 installed in it, of cooling pockets and of facilities for loose material loading 3 and unloading 4. The drum is made with guiding elements in form of three rectangular strips with laps of rectangular shape for cooling pockets. The rectangular strips are bent alternately into opposite sides at angle of 140° along cuts made at 60° to each other and to lengthwise edges of the strips thus forming equilateral triangles along length of the strip; also the triangles are arranged alternately into opposite sides. The strips are interconnected along their lengthwise edges at angle of 70° and along internal perimetre they form three broken screw grooves of main direction and two broken screw grooves of opposite direction. Along external diametre the strips form three broken screw lines of main direction and two broken screw lines of opposite direction, where in the salient points there are located converging places of sides of six equilateral triangles.

EFFECT: simplified assembly of structure and lengthwise transfer of loose material particles from loading to unloading at horizontal position of drum.
