Threadingly extend several through holes of arrangement, the through hole connects the hollow-core construction.
In one preferred embodiment of this utility model, the outer wall of the dehydration roll is made up of capillary materials, the capillary material
Pore is provided with material.
In one preferred embodiment of this utility model, the dehydration roll both ends of the surface seal setting.
In one preferred embodiment of this utility model, described capillary layer one end connects bearing, and the other end connects driving means,
The driving means can drive the capillary layer to rotate along own axes.
In one preferred embodiment of this utility model, also it is disposed between the wet vacuum tank and the dry vacuum case
Two dehydration rolls and a table roll.
In one preferred embodiment of this utility model, the forming net bottom of annular is supported by idler roller and according to certain
Tension force is tightened.
In one preferred embodiment of this utility model, from the table roll to the forming net bottom the dry vacuum case also
It is provided with collecting board.
This utility model solves defect present in background technology, and this utility model possesses following beneficial effect：
（1）Dehydration roll outermost layer adopts capillary layer made by capillary materials, it is ensured that the water energy of forming net bottom surface is enough turned round and look at soon
Being flowed in pore for speed, is not result in that the plain boiled water stream that forming net oozes out arranges vacuum equipment in other positions, dehydration roll,
Ensure that the water in pore quickly can be sucked away.
（2）By the rotation of dehydration roll, a certain amount of plain boiled water can be seized and be accommodated to thread groove, and rotary course can be by
The thread groove position principle paper of plain boiled water is equipped with, then plain boiled water can be siphoned away by vacuum drawn by through hole, dehydrating effect
It is relatively good, serve energy-saving effect.
（3）The plain boiled water that the positions such as forming board, table roll, dehydration roll, wet vacuum tank and dry vacuum case can be trickled down by collecting board
Accept, arbitrarily will not trickle down.

Specific embodiment
This utility model is described in further detail presently in connection with drawings and Examples, these accompanying drawings are simplified
Schematic diagram, only illustrates basic structure of the present utility model in a schematic way, therefore which only shows the structure relevant with this utility model
Into.
As depicted in figs. 1 and 2, a kind of energy-efficient dehydration screen cloth, including：Forming net, and run along forming net top
Breast roll, forming board, table roll, dehydration roll, wet vacuum tank, dry vacuum case, ornamenting roller and couch roll that direction sets gradually, its feature exist
In, it is hollow-core construction at the dehydration roll axle center, and hollow-core construction connects vacuum equipment, the outer surface of the dehydration roll is provided with
Along the thread groove that its axial screw extends, the thread groove bottom arranges several through holes for threadingly extending arrangement, institute
State through hole and connect the hollow-core construction.
Capillary layer has the material with pore to make, and capillary materials are made up of the resin for being doped with temperature-sensitive material, then
By the resin for heating doping, in causing resin, thermo-sensitive material is gradually separated out, and is deformed into countless pores, therefore sets in resin
Fat has certain air-and water-permeable performance, and quickly a small amount of squeeze water can be directed in the resin of capillary material.
Resin possesses certain pliability in itself, and when two vacuum furnaces are mutually extruded, a certain degree of deformation that capillary layer is produced is led
The planar structure of the region formation one fixed width of two vacuum furnace extruding is caused, pressurised zone significant surface is adds somewhat to
Product, squeezing effect are more preferable.
By the rotation of dehydration roll, a certain amount of plain boiled water can be seized and be accommodated to thread groove, and rotary course will can hold
