Abstract
The invention discloses a headbox for a low-speed paper machine. The headbox for the low-speed paper machine comprises a box body, a pulp distributor branch pipe for inputting pulp into the box body, and a breast roll; a hole roll and two separating plates are arranged in the box body; a pulp feeding device is arranged on the box body and positioned to the right side of each separating plate; the two separating plates are equipped with angular sections and arc-shaped bottom parts; an arc-shaped bulge is arranged at the bottom part of the box body, corresponding to the bottom part of each separating plate. The headbox for the low-speed paper machine has the advantages that the arc-shaped bottom parts of the separating plates are matched with the arc-shaped bulges at the bottom part of the box body, the section of an opening between the arc-shaped bottom parts and the arc-shaped bulges is gradually reduced and then gradually expanded, so that pulp can rotationally flow well through the continuously-varied fracture, and as a result, the pulp homogenizing effect is improved, and the paper quality is raised.
Description
technical field:
The present invention relates generally to head box technical field, particularly relates to a kind of head box for low-speed paper machine.
background technology:
Head box is a key component of paper machine, and the stuctures and properties of head box is for the ru nnability of the formation of page, paper machine, so that the quality of paper all has important impact.To its requirement be: 1) effective loosen collagen fibre, prevent fleeces from gathering.2) keep stable slurry speed and the relation of network speed, and will be convenient to control and regulate.3) Liu Jiang road device interior level and smooth, there is no hanging, be convenient to cleaning.But in prior art, the technology for homogenization effect aspect still compares shortcoming.
summary of the invention:
The object of the invention is exactly the defect in order to make up prior art, and provide a kind of head box for low-speed paper machine, it has better homogenization effect.
The present invention is achieved by the following technical solutions:
A kind of head box for low-speed paper machine, include casing, in casing, input the portion of paper pulp slurry device arm and breast roll, hole Gun He bis-road dividing plate is provided with in described casing, the position, right side casing being positioned at dividing plate is provided with quetsch, it is characterized in that: the cross section of described twice dividing plate is angle-style, and the bottom of dividing plate is set to arc, and the lower portion of the corresponding each dividing plate of bottom half is provided with arc convex.
For a head box for low-speed paper machine, it is characterized in that: distance minimum between the curved bottom of described dividing plate and arc convex is 0.5-3mm.
For a head box for low-speed paper machine, it is characterized in that: distance minimum between the curved bottom of described dividing plate and arc convex is 2mm.
Advantage of the present invention is:
In structure of the present invention, the curved bottom of dividing plate and the arc convex of bottom half cooperatively interact, the cross section of oral area becomes large gradually after first diminishing gradually between the two, make paper pulp after the fracture of so continuous change flows out, form better eddy flow, obtain better homogenization effect, improve the quality of paper.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
detailed description of the invention:
See accompanying drawing.
A kind of head box for low-speed paper machine, include casing 1, in casing 1, input the portion of paper pulp slurry device arm 2 and breast roll 3, hole roller 4 and two road dividing plates 5 are provided with in described casing 1, the position, right side casing 1 being positioned at dividing plate is provided with quetsch 6, the cross section of twice dividing plate 5 is angle-style, and the bottom of dividing plate is set to arc 7, and bottom casing 1, the lower portion of corresponding each dividing plate 5 is provided with arc convex 8.
Distance minimum between the curved bottom 7 of dividing plate and arc convex 8 is 2mm.
