Abstract

The invention relates to the field of papermaking machines, in particular to a novel flow box. The novel flow box comprises a box body. At least two pulp distribution devices are arranged inside the box body and arranged vertically in a layered mode. The pulp distribution devices work independently. The novel flow box is simple in structure, convenient to use, practical, one flow box can convey two or more kinds of sizing agents to a paper machine at the same time, and the pulp mixing operation performed before pulp enters the flow box is omitted.

Description

technical field [0001] The invention relates to the field of papermaking machinery, and more specifically, relates to a novel headbox. Background technique [0002] The function of the headbox is to receive the pulp sent by the flushing pump, convert the pipeline pulp flow into a uniform width, which is equal to the width of the paper machine, and form a rectangular pulp flow with a uniform flow rate in the longitudinal direction of the paper machine. The existing headbox has only one set of pulp distributing device. If papermaking wants to use two or more kinds of pulp, the pulp mixing operation must be carried out before the pulp enters the headbox. Contents of the invention [0003] The present invention provides a novel headbox for overcoming at least one defect described in the above-mentioned prior art. The invention is simple in structure, convenient and practical, can realize one headbox to deliver two or more kinds of pulp to the paper machine at the same time, a...
