Inhale dual water removal effect.
Description of the drawings
With reference to the accompanying drawings and examples this utility model is further illustrated；
Fig. 1 is the structural representation of preferred embodiment of the present utility model；
In figure：1st, upper roller, 2, lower roll, 3, capillary layer, 4, air-flow guide layer, 5, ventilating area, 6, seal area, 7, paper.
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 shown in figure 1, a kind of high-efficiency vacuum squeezing roller group for papermaking, including：Two mutually press together it is true
Empty roller, and two vacuum furnaces are setting up and down, respectively upper roller and lower roll, are hollow-core construction at vacuum furnace axle center, and pass through end
Connection vacuum equipment, the roller wall of vacuum furnace includes double-layer structure, air-flow guide layer respectively with air-vent and is located at air-flow
Capillary layer outside guide layer, capillary layer can circling gas flow guide layer it is for the relative rotation, upper roller interior air-flow guide layer it is ventilative
The air-vent of hole and lower roll interior air-flow guide layer is concentrated near the tangent position between upper roller and lower roll.
Two vacuum furnaces press together, and can form extruding force to paper, and squeeze out the water in paper, two vacuum
Roller outermost layer adopts capillary layer made by capillary materials, it is ensured that the water energy for squeezing out enough is turned round and look at and is quickly flowed into pore
It is interior, it is not result on paper that the water Liu Dao for pressurizeing out had been extruded.
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.
Two ventilating areas are oppositely arranged, and can pick up the moisture of paper both sides faster, define squeezing and aspirate
Dual water removal effect.
Ventilating area and seal area are provided with air-flow guide layer, intensive on ventilating area to be provided with air-vent, ventilating area is possess
One fixed width, and length direction is axially in parallel with vacuum furnace, ventilating area is located at the corresponding region that upper roller and lower roll press together.
By arrange air-flow guide layer, it is ensured that vacuum equipment is primarily directed to extrusion position and is evacuated, so can in time by
Water in the pore of capillary layer is quickly aspirated away, it is ensured that the water absorbing properties of pore remain at higher level.
Vacuum furnace both ends of the surface seal setting, capillary layer one end connection bearing, other end connection driving means, driving means
Capillary layer can be driven to rotate along own axes.
Above according to desirable embodiment of the present utility model to enlighten, by above-mentioned description, related personnel is complete
Various change and modification can be carried out in the range of without departing from this utility model technological thought.This utility model
Technical scope be not limited to the content in description, it is necessary to technical scope is determined according to right.
