    • A method for improving the operation of a disc filter used for the filtering of fluids containing solid matter such as fibers. Known filtering methods have the drawback that the rate of water exhaustion is limited, because a vacuum tends to be created inside the sectors when the filtered fluid is drained by suction from the central channel of the disc filter. This drawback is an obstacle to increasing the speed of rotation and therefore to increasing the capacity of the disc filter. With the method of the present invention, this problem is solved by providing the disc filter with a means of admitting ambient air into the disc sectors and the central shaft channel and/or with equipment for blowing air into the sectors and the channel to remove the filtered fluid from them.
    • 一种用于改善用于过滤含有固体物质如纤维的流体的盘式过滤器的操作的方法。 已知的过滤方法具有这样的缺点:排水速率受到限制,因为当滤过的流体通过来自盘式过滤器的中心通道的抽吸排出时,在扇区内容易产生真空。 这个缺点是提高旋转速度并因此增加盘式过滤器的容量的障碍。 利用本发明的方法,通过为盘式过滤器提供将环境空气进入盘扇区和中心轴通道的装置和/或用于将空气吹入扇区和通道以除去 过滤后的液体。
