Open type single-net double-flow slurry inclined net forming machine

Abstract

The invention discloses an open type single-net double-flow slurry inclined net forming machine. The forming machine comprises two flow slurry boxes, a forming net wound in a ring shape on a pluralityof driving rolls, vacuum suction boxes and homogenizing rolls. A plurality of partition plates are arranged inside the two flow slurry boxes and divided into an upper partition plate group and a lower partition plate group, the upper partition plate group includes a plurality of upper partition plates which have the same height and are arranged at equal distances, the upper ends and two sides ofthe upper partition plates are in sealed and fixed connection with top plates and two side plates of the flow slurry boxes, and gaps are formed between the lower ends of the upper partition plates andbottom plates of the flow slurry boxes; the lower partition plate group includes a plurality of lower partition plates which are arranged at equal distances and have progressively decreased height inthe flow direction of slurry, the lower ends and two sides of the lower partition plates are in sealed and fixed connection with the bottom plates and the two side plates of the flow slurry boxes, and gaps are formed between the upper ends of the lower partition plates and the top plates of the flow slurry boxes; the upper partition plates and the lower partition plates are arranged at intervals.The designed homogenizing rolls meet the characteristics of the slurry, the adjustment is convenient, and the slurry can be evenly spread to the net. Meanwhile, the vacuumizing pressure of a wet absorbing box is independently and accurately controlled to ensure uniform dehydration.

Description

technical field [0001] The invention relates to the field of paper machine formers, in particular to special paper paper machine formers. Background technique [0002] At present, most of the forming equipment for special paper in my country is fourdrinier forming and cylinder forming, with poor technical equipment and backward control methods, it is difficult to meet the market demand for multi-variety, small-batch and high-performance special paper. In recent years, the production process of special paper is gradually changing from traditional Fourdrinier forming and rotary forming to inclined forming. Compared with fourdrinier forming and rotary forming, inclined wire forming has lower netting concentration, better dehydration performance, higher sheet uniformity and longer fiber length, suitable for paper with high air permeability (such as filter paper) and glass fiber paper , wet-laid non-woven fabrics and other special paper production. Although inclined wire formin...

Problems solved by technology

[0008] The present invention provides an open type single-net double-flow pulp inclined-net former, which solves the problem that in the prior art, only paper composed of one kind of pulp can be made at a time, and the fiber pulp is not refined and evenly distributed, which easily leads to settlement, Flocculation and large-scale turbulence, technical issues affecting the vertical and horizontal distribution of fibers on the web and paper properties
