A first forming plate batten is parallel to other forming plate battens and is mounted and fixed on the upper portion of a forming plate body, is attached close to a forming table, the number of the forming plate battens on the forming plate body is increased by 10%-50% relative to the number of the forming plate battens of a traditional multi-cylinder long mesh paper machine of identical width and speed, and the problems of a traditional forming plate in processing high packing paper making process are solved. The forming plate on the mesh part gravity dehydration system of the multi-cylinder long mesh paper machine has the advantages of enabling high packing paper pulp to carry out natural dehydration well and paper sheets to be formed evenly.
Description
Technical field
The invention discloses the forming board in a kind of multi-cylinder long mesh paper machine wet end gravity dehydration system, belong to paper making equipment accessory field, be used on the paper making equipment of producing high filler paper, be particularly suitable for being used in and using on the paper production equipment of active calcium silicate as papermaking filler.
Background technology
Paper-making industry is that China Today (the Ye Shi world) consumes also one of large industry of the large and actual demand amount of Environmental costs, although Internet technology is advanced by leaps and bounds, but along with the develop rapidly of China's economic and global economy continue advance, China and the world do not change the aggregate demand of paper product, also slightly increase, demand to paper product, mean the demand to paper making pulps, and prepare the forest growth rate of paper making pulps far below the requirement consumes speed of paper making pulps, under the constant prerequisite of paper products total output, how to reduce paper making pulps consumption, and can produce high-quality paper, that one global problem pendulum is in face of the mankind.
Untie early this road difficult problem, significant to China.At present, the most of dependence on import of China's paper making pulps, import pulp amount has leapt to the first in the world, from strategic angle, the papermaking of China " with slurry " is in fact the use of " limited ", if You Yitian world wood pulp supply chain supply shortage, China is by " with slurry " the exhausted problem in the face of fearful, can directly threaten national security stable, the forest reserves of China are very limited, be difficult to the own paper product of reply and supply with, the China that does not first analyze today is here one of paper product state in short supply of maximum in the world still.
Based on above-mentioned, people are studying always and are finding high filler paper production technology and production equipment thereof, to untiing early an above-mentioned difficult problem.
Paper machine is the equipment of combining of paper making, and traditional paper machine mainly contains three types: long mesh paper making machine, cylinder mould machine, foudrinier.Wherein long mesh paper making machine is a kind of widely used paper machine type, and most paper grades of can manufacturing paper with pulp, is the mainstream model of paper machine.
Forming board in long mesh paper making machine gravity dehydration system is a significant components in paper machine production equipment, as shown in Figure 1, forming board in tradition long mesh paper making machine gravity dehydration system: article one forming board lath 4 and many forming board laths 3 are parallel to each other, be fixed on shaping plate body 2 tops, be close to forming table 1, width of sheet is all D`, shaping plate body 2 integral width are A`, tradition forming board is suitable for slowly dehydration and the shaping of common paper pulp, when using high filler paper pulp, because natural-dehydration speed is slow, the quantity of forming board lath and gap arrangement have hindered the dehydration of paper pulp, can not effectively promote the ordered arrangement of paper pulp fiber and filler, paper sheet formation weak effect.Fig. 3 is that forming board is arranged on the use view in conventional paper machines gravity dehydration system.
How to address the above problem, be one of people's important step of successfully developing high loaded sheet machine equipment.
Summary of the invention
The object of this invention is to provide the forming board in a kind of multi-cylinder long mesh paper machine wet end gravity dehydration system, it has can make the paper pulp natural-dehydration of high filler and the feature that page is evenly shaped well.
The object of the present invention is achieved like this: the forming board in a kind of multi-cylinder long mesh paper machine wet end gravity dehydration system, its article one forming board lath and other forming board laths are parallel to each other, be fixed on shaping plate body top, be close to forming table, traditional fourdrinier wire wire multi-cylinder paper machine forming board lath quantity of the relatively equal fabric width of forming board lath quantity and the speed of a motor vehicle increases 10%-50%;
The length A ` in traditional fourdrinier wire wire multi-cylinder paper machine forming board region of the relatively equal fabric width of the length A in forming board region and the speed of a motor vehicle increases 10%-50%;
Forming board lath quantity has 5-10 bar;
The bar forming board lath being parallel to each other is fixed on shaping plate body top, and article one forming board width of sheet of close head box is between 150mm-300mm;
The width of other forming board laths equates, between 50mm-80mm;
Installation interval between forming board lath is between 60-80mm.
Advantage of the present invention is: due to the structural change of forming board of the present invention, region lengthens, not only extended the paper pulp natural-dehydration time, also make paper pulp forming board drape forming evenly, dehydration is good, solved the problem that traditional forming board exists when producing high filler paper;
Because forming board of the present invention has adopted the structure of optimal design, make forming board region in the situation that not exerting an influence paper sheet formation turbulent flow, dewatering time extends, significantly increase the water separation capability of wet pulp, and fiber rapid subsidence is arranged as orderly l Water Paper page in fast dewatering, solved traditional forming board region when producing high filler paper, the poor problem of the slow paper forming effect of dewatering speed.
