Abstract
The invention discloses a mesh wet vacuum dehydration system used for a multi-cylinder long mesh paper machine, and belongs to the field of accessories of paper making equipment. The mesh wet vacuum dehydration system comprises a wet vacuum box which is provided with a dehydration plate in contact with a forming table, the middle of the wet vacuum box is a wet vacuum box vacuum chamber, and the length of a mesh wet vacuum dehydration system area is increased by 10%-50% than that of a mesh wet vacuum dehydration system area of a traditional multi-cylinder long mesh paper machine with the same width and the same speed. The mesh wet vacuum dehydration system has the advantages that paper pulp dwell time is long, the dehydration degree is high, orderly distribution of paper pulp fibers and padding can be effectively promoted, and the paper sheet shaping effect is good. The problem that a traditional mesh wet vacuum dehydration system is not suitable for being used for production of high padding paper pulp paper sheets is solved.
Description
Technical field
The invention discloses and a kind ofly for the wet vacuum dewatering system of the wet end on multi-cylinder long mesh paper machine, belong to paper machine equipment accessory field, be suitable for being used on the paper machine of producing high filler paper, be particularly suitable for being used in and using on the paper machine of active calcium silicate as high filler papermaking.
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 be accompanied by 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 is short, 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.
The wet vacuum dewatering system of long mesh paper making machine wet end is an important component part in paper machine equipment.
As shown in Figure 1, 2, the wet vacuum dewatering system of traditional web part of paper machine, is provided with dewatering plate 3 on wet vacuum tank 2 and contacts with forming table 1, and middle part is wet vacuum tank vacuum chamber 4; When selecting high filler paper pulp to produce, there are the following problems:
1, paper pulp is short in the wet vacuum dehydration region time of staying of wet end, and dehydration is not enough, and meanwhile, wet web is shaped poor;
2, the dewatering plate of the wet vacuum dewatering system of traditional wet end is applicable to slowly dehydration and the shaping of common paper pulp, when using high filler paper pulp, in whole wet vacuum dewatering system region, the arrangement in the deficiency of dewatering plate total number and dewatering plate gap hinders the dehydration of paper pulp, cause high filler paper pulp dewatering speed slow, do not have the effect of effective promotion paper pulp fiber and filler ordered arrangement, paper sheet formation weak effect.
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 a kind ofly for the wet vacuum dewatering system of the wet end on multi-cylinder long mesh paper machine, it has, and the paper pulp time of staying is long, degree of dehydration is high, can effectively promote paper pulp fiber and filler ordered arrangement, the effective feature of paper sheet formation.
The object of the present invention is achieved like this: a kind of for the wet vacuum dewatering system of the wet end on multi-cylinder long mesh paper machine, the wet vacuum dewatering system of wet end is comprised of the vacuum tank that wets, on wet vacuum tank, dewatering plate being installed contacts with forming table, middle part is wet vacuum tank vacuum chamber, and the wet vacuum dewatering system zone length of traditional multi-cylinder long mesh paper machine wet end of the relatively equal fabric width of the wet vacuum dewatering system zone length of wet end and the speed of a motor vehicle increases 20%-100%;
