Abstract

<B>"PROCESSO E APARELHO PARA LAVAGEM DE MISTURA DE POLPA DE FIBRA"<D> Processo e aparelho para lavagem de uma mistura de polpa de fibra, através dos quais a água, assim como, as cinzas e outras impurezas tipo partícula nela contidas são removidas da mistura de polpa de fibra. No processo, a polpa de fibra que está sendo lavada é alimentada entre as duas telas de arame (1,2) de modo que a água e as cinzas são removidas da polpa de fibra através de ambas telas de arame (1,2), após o que as telas de arame (1,2) e a polpa de fibra contida entre estas são conduzidas para correr ao longo de uma superfície curva para remover qualquer água extra por meio de pressão das telas de arame (1,2) e da força centrífuga. O aparelho possui duas telas de arame (1,2) e uma seção de secagem (3) entre as telas de arame (1,2) e a água e impurezas são removidas na seção de secagem (3) através de ambas telas de arame (1,2).<B> "PROCESS AND APPLIANCE FOR WASHING A FIBER PULP MIXTURE" <D> Process and apparatus for washing a mixture of fiber pulp, through which water, as well as ash and other particulate impurities contained therein are removed from the fiber pulp mixture. In the process, the fiber pulp being washed is fed between the two wire screens (1,2) so that water and ash are removed from the fiber pulp through both wire screens (1,2), whereupon the wire screens (1,2) and the fiber pulp contained between them are conducted to run along a curved surface to remove any extra water by pressing the wire screens (1,2) and the centrifugal force. The apparatus has two wire screens (1,2) and a drying section (3) between the wire screens (1,2) and water and impurities are removed in the drying section (3) through both wire screens (1,2).
