(ZH) 一种筛选疏解机
Abstract:
(EN) Disclosed is a screening and deflaking machine for solving the problem in the prior art of pulp screening machines only being capable of screening pulp and not deflaking. The screening and deflaking machine comprises a screen cylinder (1) and a rotor (2) provided in the screen cylinder, wherein the screen cylinder (1) rotates relative to the rotor (2), the rotor (2) comprises a positive pressure section (21) and a negative pressure section (22), an arc transition section (23) is provided between the positive pressure section (21) and the negative pressure section (22) of the rotor (2), the arc transition section (23) and the screen cylinder (1) are concentric, and a deflaking area is formed between the arc transition section (23) and the screen cylinder (1). The screening and deflaking machine has a simple structure and is convenient to use, can achieve multiple purposes in one machine, does not require additional installation of a separate deflaker, and has good practicability.
(FR) L'invention concerne une machine de criblage et de dépastillage permettant de résoudre le problème dans l'état de la technique des machines de criblage de pâte, uniquement en mesure d'effectuer un criblage de la pâte et pas un dépastillage. La machine de criblage et de dépastillage comporte un cylindre formant crible (1) et un rotor (2) mis en œuvre dans le cylindre formant crible, dans lequel le cylindre formant crible (1) tourne par rapport au rotor (2), le rotor (2) comporte une section de pression positive (21) et une section de pression négative (22), une section de transition d'arc (23) est mise en œuvre entre la section de pression positive (21) et la section de pression négative (22) du rotor (2), la section de transition d'arc (23) et le cylindre formant crible (1) sont concentriques, et une zone de dépastillage est formée entre la section de transition d'arc (23) et le cylindre formant crible (1). La machine de criblage et de dépastillage présente une structure simple et est pratique à utiliser, peut réaliser de multiples objectifs dans une machine, ne nécessite pas l'installation supplémentaire d'un dépastilleur séparé, et présente un bon aspect pratique.
(ZH) 一种筛选疏解机,用以解决现有技术中纸浆筛选机只能对纸浆进行筛选而无法进行疏解的问题。该筛选疏解机包括筛鼓(1)和设置于筛鼓内的旋翼(2),筛鼓(1)与旋翼(2)相对转动,旋翼(2)包括正压区段(21)和负压区段(22),旋翼(2)的正压区段(21)和负压区段(22)之间为圆弧过渡段(23),圆弧过渡段(23)与筛鼓(1)之间同心,圆弧过渡段(23)与筛鼓(1)之间形成疏解区。该筛选疏解机结构简单,使用方便,能够实现一机多用,无需另外设置单独的疏解机,具有很好的实用性。
