OPTICAL SEPARATOR WITH COOLING SYSTEM Russian patent published in 2024 - IPC G01N21/47 B07C5/342 

FIELD: various technological processes.

SUBSTANCE: invention relates to separation of multi-coloured material and can be used in mining, glass, food, light, chemical and other industries in installations for recycling scrap glass. Optical separator with a cooling system includes a housing with a device for feeding multi-coloured material, a pitched glass, illuminators, an optical sensor, behind which, in the direction of movement of the material, a sorting system is installed, which is connected to a control unit of the separator operation. Sorting system is equipped with a number of blowing nozzles, each of which is connected to a compressed air supply system, which is also connected to a control unit. Optical separator is equipped with a cooling system comprising three heat exchange units serving to remove heat from light sources, namely background and front illumination lamps and a detection system. Besides, the cooling system is equipped with an air supply unit with a filtering element, which is also connected to an air blower and a pipeline for supplying air from the atmosphere. Optical sensor is made in the form of an optical unit equipped with a sealed housing, into which compressed air is supplied through a hose to create excess pressure inside. In the housing of the optical unit there is a front illumination lamp and a detection system, each of which is equipped with its own heat exchange unit. Also, the heat exchange unit is equipped with a background illumination lamp located outside the housing of the optical unit, behind the back face of the pitched glass. Heat exchange units of the lamps are made in the form of hollow aluminium profiles, on one of the outer walls of which there are light-emitting diode light sources which release heat transmitted through the wall of the profile to its inner cavity. Heat exchange unit of the detection system is equipped with a radiator in the form of an aluminium profile located on the inner wall of the housing of the optical unit. Opposite the radiator there are two circulating fans directing the heated air into the flow of passing cooling air. Cooling air from the atmosphere is supplied to all units of the cooling system through a filter element of the air supply unit via pipeline by an air blower.

EFFECT: increasing the efficiency of cooling individual elements and separator units by using a cooling system with three heat exchange units, which reduce thermal emissions from the detection units and front and background illumination lamps.
