Abstract

The utility model discloses a shape-forming plate for a mesh portion gravity dehydrating system of a multi-cylinder long mesh paper machine. A first shape-forming plate strip is parallel to other shape-forming plate strips, is fixedly arranged on the upper portion of the shape-forming plate and is attached closely to the mesh table. The number of the shape-forming plate strips of the shape-forming plate is increased by 10 percent to 50 percent compared with that of a traditional multi-cylinder long mesh paper machine with same breadth and vehicle speed. The shape-forming plate for the mesh portion gravity dehydrating system of the multi-cylinder long mesh paper machine solves the existing problem of the traditional shape-forming plate when processing high-temperature loadings in the process of paper making, and has the advantages that the high-temperature pulp loading can be naturally dehydrated and the high-temperature pulp loading and a paper sheet are evenly formed.

Description

Forming board in the multi-cylinder long mesh paper machine wet end gravity dehydration system

Technical field

The utility model 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 on the paper production equipment of active calcium silicate as papermaking filler.

Background technology

Paper-making industry is that China Today (also being the 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 the forest growth rate of preparation paper making pulps is far below the requirement consumes speed of paper making pulps, under the constant prerequisite of paper products total output, how reducing the paper making pulps consumption, and can produce high-quality paper, has been 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, the 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 world's wood pulp supply chain supply shortage in a day is arranged, China will be in the face of fearful " with slurry " exhausted problem, it is stable directly to threaten national security, 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 analyze first today here is one of paper product state in short supply of maximum in the world still.

Based on above-mentioned, people are studying always and are seeking high filler paper production technology and production equipment thereof, in the hope of untiing early an above-mentioned difficult problem.

Paper machine is the equipment of uniting 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 the long mesh paper making machine gravity dehydration system is a significant components in the paper machine production equipment, as shown in Figure 1, forming board in the 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 all is D`, shaping plate body 2 overall width are A`, the 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, the paper sheet formation weak effect.Fig. 3 is that forming board is installed in the use view in the 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 purpose of this utility model provides the forming board in a kind of multi-cylinder long mesh paper machine wet end gravity dehydration system, and it has the advantages that the paper pulp natural-dehydration that can make well high filler and page evenly are shaped.

The purpose of this utility model is achieved in that 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 zone of the relatively equal fabric width of the length A in forming board zone and the speed of a motor vehicle increases 10%-50%;

Forming board lath quantity has the 5-10 bar;

The bar forming board lath that is 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 the forming board lath is between 60-80mm.

The utility model has the advantages that: because the structural change of forming board described in the utility model, the zone lengthens, not only prolonged the paper pulp natural-dehydration time, also so that paper pulp is even in the forming board drape forming, dehydration is good, has solved the problem that traditional forming board exists when producing high filler paper;

Because forming board described in the utility model has adopted the structure of optimal design, so that the forming board zone is in the situation of paper sheet formation turbulent flow that do not exert an influence, dewatering time prolongs, significantly increase the water separation capability of wet pulp, and the fiber rapid subsidence is arranged as orderly l Water Paper page or leaf in fast dewatering, solved traditional forming board zone when producing high filler paper, the poor problem of the slow paper forming effect of dewatering speed.
