Abstract
Patente de Invenção: <B>"MéTODO E APARELHO PARA MANTER FLUXO UNIFORME DE MASSA EM MATERIAL GRANULAR PARA FORA DE UM RECIPIENTE"<D>. Método e aparelho para manutenção de um fluxo de massa susbstancialmente uniforme de material granular para fora de um recipiente. O aparelho inclui uma porção de transição convergente definindo uma abertura de entrada, que converge para uma abertura de saída. A abertura de saída tem uma dimensão de abertura transversal (x). Uma porção de chaminé alongada é acoplada à porção de transição convergente, na abertura de saída. A porção de chaminé alongada tem uma dimensão de altura (y). A proporção da dimensão de abertura transversal (x) em relação à dimensão de altura (y) é determinada por um ângulo de repouso do material granular para manter um fluxo de massa substancialmente uniforme de material granular.Invention Patent: <B> "METHOD AND APPARATUS TO MAINTAIN UNIFORM FLOW OF MASS IN GRANULAR MATERIAL OUT OF A CONTAINER" <D>. Method and apparatus for maintaining a substantially uniform mass flow of granular material out of a container. The apparatus includes a converging transition portion defining an inlet opening, which converges to an outlet opening. The outlet opening has a transverse opening dimension (x). An elongated chimney portion is coupled to the converging transition portion, at the outlet opening. The elongated chimney portion has a height (y) dimension. The ratio of the transverse opening dimension (x) to the height dimension (y) is determined by an angle of rest of the granular material to maintain a substantially uniform mass flow of granular material.
