Abstract

"APERFEIçOAMENTOS INTRODUZIDOS EM FORNO GIRATóRIO DE ALTO RENDIMENTO CALORìFICO PARA FABRICAçãO DE SEMI-HIDRATO E ANIDRITA II". O forno é dotado de uma série de pás sobre a superfície do material refratário e ligadas ao corpo tubular interno, e é dotado, em sua parte posterior, de uma câmara adaptada para receber pó de gesso recuperado previamente no filtro de manga da instalação, assim como de suportes deslizantes, que permitem o deslocamento linear, entre os diferentes corpos tubulares concêntricos, que formam o forno, de uma parte de lareira porta-queimador móvel, de um ou vários anéis de retenção, dotados de orifícios passantes, ligados ao corpo cilíndrico interno, que limitam a passagem do material de cocção através dos mesmos e regulam a velocidade de passagem do material, de nervuras em segmento de espiral, que exercem uma retenção do material, regulando sua passagem pelas aberturas de saída, e de uma tampa de estanqueidade, ligada ao chassi de rodagem e dotada de uma saída de vapor em comunicação com um conduto de aspiração de gases, de uma porta para a amostragem e de um suporte para sondas."IMPROVEMENTS INTRODUCED IN HIGH CALORIC INCOME ROTATING OVEN FOR MANUFACTURE OF SEMI-HYDRATE AND ANHYDROTE II". The furnace is provided with a series of blades on the surface of the refractory material and connected to the inner tubular body, and is provided at its rear with a chamber adapted to receive previously recovered plaster dust on the sleeve filter of the installation as well. as sliding brackets, which allow linear displacement between the different concentric tubular bodies forming the furnace of a movable burner fireplace part, one or more retaining rings with through holes connected to the cylindrical body limiting the passage of the cooking material therethrough and regulating the speed of passage of the material, of spiral-segmented ribs retaining the material by regulating its passage through the outlet openings, and a tightness cap connected to the chassis and fitted with a steam outlet in communication with a gas suction duct, a sampling port and a port for probes.
