DEVICE FOR THERMAL TREATMENT OF CONSTRUCTION MATERIALS AND ITEMS FROM THEM Russian patent published in 2015 - IPC B28B11/00 B28B11/24 

FIELD: construction.

SUBSTANCE: device for thermal treatment of construction materials and items from them comprises a chamber with generators of infrared radiation, heat-insulated doors, a control panel, devices and instruments regulating parameters of emission flows and internal pressure in the chamber. Generators are made as paired symmetrically infrared emitters and reflectors of complex configuration made of curvilinear sections creating a reflector in the form of two mirror cylindrical surfaces symmetrical relative to the vertical plane of the chamber of cylindrical surfaces having a common line. In the cross section the centres of curvature of curvilinear sections of the reflector in the chamber are arranged on a straight line stretching via centres of infrared emitters. At the same time radii of curvature of curvilinear sections of reflectors are related to each other as 1:π:π². The chamber is made as closed. On side internal surfaces of the chamber vertically and in the arch of the chamber there are horizontally installed identical generators of infrared radiation. At the same time in each generator in the cross section the centres of curvature are arranged on straight lines crossing at the angle of 60° , one of which stretches via the centres of infrared radiators installed inside the sections of smallest radius of curvature. Centres of the largest radius of curvature are tops of equilateral triangles, the base of which is a section of a straight line that connects centres of smallest radii of curvature, at the same time completion of the largest radius of curvature. At the same time radii of largest curvature of vertically and horizontally installed generators start from one point.

EFFECT: increased quality and strength of items due to even distribution of heat along area and depth of infrared radiation penetration.
