POWER-EFFECTIVE UNIT FOR ECOLOGICALLY SAFE PROCESS OF PRODUCTION OF POLYSTYRENE AGGREGATE FOR CONCRETE Russian patent published in 2002 - IPC

Abstract RU 2182870 C2

FIELD: civil engineering, applicable in equipment for manufacture of polymeric aggregate for concrete. SUBSTANCE: the unit has an apparatus for foaming of starting polystyrene granules with an agitating device, apparatus for an additional heat treatment of foamed granules with an agitating device, service hopper, loading- unloading device, system of service lines and test and measuring instruments. It is provided with a service hopper with a screw feeder for feeding of prefoamed polystyrene granules to the foaming apparatus. Mounted in the upper part of the apparatus for heat treatment of foamed granules are a sealing cap, special gate unit, deactivator, fan and a gaseous detoxicant generator. EFFECT: reduced noxious effluents into the atmosphere, reduced density of polystyrene aggregate and reduced specific power consumption. 2 cl, 1 dwg
