Stock inlet for paper-making machine - has sections where mixed part flows from a common feed to set suspension compsn. according to use

摘要

The stock inlet, for a paper-making machine, has a divided feed system to deliver suspensions with different characteristics. a feed for a common compsn. is divided into separate paths or channels. At least one divider is at least in one channel to separate the suspension into selected parts. A channel to carry the suspension away and a channel to carry it onwards is at each divider. At least two dividers, in succession, are in at least one channel, or they are parallel to each other. A flow control is at the common feed, and each channel has an individual flow control. Each divider is separately controlled, using a sifter, hydrocyclone or a centrifugal separator. At least one separator serves several sections, and at least one section is served by separators. USE/ADVANTAGE - The stock inlet, across the width of the paper-making machine, delivers the fibre suspension pulp according to the paper type and quality to be produced. The system allows suspension to be structured according to use, from a common feed, and gives sections of suspension delivery independent of each other.
