Abstract

PROCESSO PARA A DRENAGEM DE POLPA E MáQUINA DE DRENAGEM PARA A EXECUçãO DO PROCESSO. A invenção se refere a um processo para a drenagem de polpa (2) em um modelador (3), no qual a polpa introduzida por um regulador (7) em uma peneira inferior (4) é conduzida, por um cilindro de desvio (8) , entre a peneira inferior (4) e uma peneira superior (5), formando uma área de peneira dupla (6), no minimo, em partes. O processo de acordo com a invenção é caracterizado pelo fato de que a polpa (2) é drenada previamente em uma área de drenagem prévia (9) disposta no sentido de peneira (S) da peneira inferior (4) por meio da peneira inferior (4), e que a polpa (2) é novamente drenada na área de peneira dupla (6) que apresenta um outro cilindro de desvio (13) por meio de tensões de peneira (T4, T5) exercidas pelas duas peneiras (4, 5) A invenção se refere ainda a uma máquina de drenagem (1) para a polpa (2), que é adequada para a execução do processo de acordo com a invenção.PULP DRAINING PROCESS AND DRAIN MACHINE FOR PROCESSING. The invention relates to a process for draining pulp (2) into a shaper (3), in which pulp introduced by a regulator (7) into a lower screen (4) is driven by a bypass cylinder (8). ) between the lower sieve (4) and an upper sieve (5), forming a minimum double sieve area (6) in parts. The process according to the invention is characterized in that the pulp (2) is pre-drained into a pre-draining area (9) arranged in the sieve direction (S) of the lower sieve (4) by means of the lower sieve ( 4), and that the pulp (2) is again drained into the double sieve area (6) having another bypass cylinder (13) by means of sieve tensions (T4, T5) exerted by the two sieves (4,5). The invention further relates to a drainage machine (1) for the pulp (2), which is suitable for carrying out the process according to the invention.
