COKE COOLING MACHINE Russian patent published in 2017 - IPC C10B39/10 

FIELD: metallurgy.

SUBSTANCE: machine for coke cooling includes a water bath, a rotating drum mounted therein, devices for loading and unloading of clinker. The drum is mounted in sections serially connected with each other along the length of the drum through their end openings in the form of polygons. Each section is made up of two subsections, the first subsection around the perimeter assembled from an even number of at least four identical first isosceles triangles, the sides of which are alternately connected with the lateral sides of at least four identical second isosceles triangles which bases are greater than the base of the first four isosceles triangles, with formation of small and large end openings shaped as polygons, the second subsection is assembled from at least four identical equilateral triangles alternately connected along the perimeter with sides equal to the bases of the second isosceles triangles of the first sub-section, with the sides of at least four identical isosceles triangles with a 90° apex angle with the formation of small and large end openings shaped as polygons, where the big end opening shaped as the polygon of the first subsection is equal to the small end opening shaped as the polygon of the second subsection. The subsections are coupled together into sections through their end openings in the form of polygons. Along the whole length of the drum a conical spring with turns is mounted and equipped with a device for changing its pitch by tension or compression. Its turn direction is opposite to the direction of drum rotation and its taper matches with the taper of the drum.

EFFECT: efficiency enhancement.
