Abstract

El invento se refiere a una máquina concebida como columna neumática de flotacion, la que presenta una carcasa consistente en una parte superior más amplia y en una parte inferior, un tubo interno que se halla dentro de la parte superior más amplia y que la divide en cámaras de flotacion básica y de postflotacion (1,resp. 3), así como en un recipiente colector de espuma que está configurado como canal de forma cronica, con tubos opuestos (7) para extraer el producto espumado. Además, el recipiente colector de espuma se encuentra ubicado preferentemente sobre la parte externa del tubo interior, dentro de la parte interior de la parte superior más amplia de la carcasa, entre las cámaras de flotacion básica y la de postflotacion (1, resp. 3), y está realizado preferentemente con una inclinacion de su fondo de entre aprox. 45 degree hasta aprox. 60 degree respecto de la superficie horizontal. Un ángulo como este garantiza la mejor capacidad de transporte de los productos espumados. El invento provoca un incremento en la productividad de la máquina después del espumado a través de la exclusion de la posibilidad de entremezclado de los productos espumados provenientes de las cámaras de flotacion básica y de postflotacion (1, resp. 3) sobre la superficie de la pulpa y a través de la exclusion de la destruccion mutua entre los aerofloculos en la capa de espuma. En la construccion de la máquina precedentemente descripta se encuentra excluida la posibilidad de entremezclado de los productos de las cámaras de flotacion básica y de postflotacion (1, resp. 3) sobre la superficie de la pulpa y la de choque y destruccion mutua entre los aerofloculos en la capa de espuma, en razon de que los productos espumados de las cámaras de flotacion básica y de postflotacion (1, resp. 3) son conducidos hacia el recipiente colector de espuma desde dos lados, es decir, desde la parte externa y desde la parte externa.The invention relates to a machine designed as a pneumatic floating column, which has a housing consisting of a wider upper part and a lower part, an internal tube that is inside the wider upper part and which divides it into Basic and post-floating flotation chambers (1, resp. 3), as well as in a foam collecting vessel that is configured as a channel chronically, with opposite tubes (7) to extract the foamed product. In addition, the foam collecting container is preferably located on the outer part of the inner tube, inside the inner part of the wider upper part of the housing, between the basic floating and post-floating chambers (1, resp. 3 ), and is preferably made with an inclination of its bottom of between approx. 45 degree to approx. 60 degree with respect to the horizontal surface. An angle like this guarantees the best transport capacity of foamed products. The invention causes an increase in the productivity of the machine after foaming through the exclusion of the possibility of intermingling of the foamed products coming from the basic and post-floating flotation chambers (1, resp. 3) on the surface of the pulp and through the exclusion of mutual destruction between the aeroflocles in the foam layer. In the construction of the machine described above, the possibility of intermingling of the products of the basic and post-floating flotation chambers (1, resp. 3) on the surface of the pulp and that of shock and mutual destruction between the aerofloccles is excluded in the foam layer, on the grounds that the foamed products of the basic and post-floating flotation chambers (1, resp. 3) are led to the foam collecting vessel from two sides, that is, from the outside and from the external part
