COKE COOLER Russian patent published in 2017 - IPC C10B39/04 C10B39/10 

FIELD: metallurgy.

SUBSTANCE: coke cooler comprises a water bath (1) mounted therein a rotating drum (2), a coke loading tool (3) and a coke dumping tool (4). Drum (2) is made of three or more bands of trapezoidal shape with different dimensions in width with increasing length. On strips alternately from opposite sides at an angle of 60° to the strips axis, zones are made of weakened cross section in the form of cuts with sloping walls forming across the perimeter of drum (2) of circular polygonal surfaces from alternately arranged equilateral and isosceles triangles. The strips are twisted in longitudinal direction relative to their longitudinal axis and curved in the transverse direction along a helical line on the tapered mandrel to form, across the drum perimeter, three or more helical lines and helical surfaces. Along the whole length of drum (2), a conical spring is mounted with turns plain section which is equipped with a device for modifying the turning pitch by tension or compression. Its turning direction is opposite to the direction of drum rotation, and its taper does not match the drum taper.

EFFECT: cooling efficiency increase.
