Abstract

Patente de Invenção: <B>"MONTAGEM PARA DESCARREGAR E MISTURAR MATERIAL GRANULOSO".<D>A invenção refere-se a uma montagem para descarregar e misturar material granuloso de um forno de cuba compreendido de um corpo oco abrindo para baixo e/ou para pelo menos um lado para descarregar o material de reação, no qual hélices para o corpo oco são radialmente arranjadas, essas hélices tendo eixos de comprimentos diferentes em um nível e/ou uma hélice sendo designada como hélice principal. Uma das combinações possíveis dos eixos em cantilever 2 de três comprimentos diferentes é montar os eixos radialmente para formar um octágono no forno de cuba 1, onde os eixos em cantilever opostos 2 têm comprimentos iguais. A área de "homem morto", isto é, o espaço inativo no centro do forno de cuba, é extremamente reduzido por essa combinação.Invention Patent: <B> "ASSEMBLY TO UNLOAD AND MIX GRANULATE MATERIAL". <D> The invention relates to an assembly for unloading and mixing granular material from a vat oven comprised of a hollow body opening down and / or for at least one side to discharge the reaction material, in which propellers for the hollow body are radially arranged, those propellers having axes of different lengths on one level and / or a propeller being designated as the main propeller. One of the possible combinations of the cantilever 2 axes of three different lengths is to mount the axes radially to form an octagon in the vat 1, where the opposite cantilever axes 2 are of equal length. The "dead man" area, that is, the inactive space in the center of the vat oven, is extremely reduced by this combination.
