High speed, use suction press roll, suction press roll can be improved dehydration efficiency, improve page quality, reduce squeezing to
Paper industry bring adverse effect.Being mainly characterized by of vacuum furnace has the lesser through-hole of many diameters on roller shell, through-hole passes through vermicelli
Layer and body layer, roller shell inner cavity maintains continuous vacuum when work.When page and blanket net enter the pressure area of pressure roller and suction press roll
When, the water in page is transferred to blanket net；When the water saturation in blanket net, under pull of vacuum effect, water is discharged from blanket net, enters
Through-hole is discharged after importing roller shell inner cavity.The effect of vacuum furnace inner cavity vacuum degree is: the moisture for forcing pressure area to be extruded passes through blanket
Net, through the through-hole on vacuum furnace, into roller shell inner cavity.This process needs the regular hour, the vacuum degree of vacuum furnace vacuum area
Higher, this time is shorter, and interior at the same time just to have more moisture to be sucked out, page dehydration is more, that is, very
The water separation capability of empty roller is stronger.Improve paper machine speed, it is desirable that the dehydration efficiency of press section of a paper machine is higher.One of method is
Improve the line pressure of pressure area；The line pressure of pressure area is bigger, and page dehydration is more, but since page may be crushed, line pressure cannot be too；
And line pressure is bigger, and the rack of press section and the rigidity of roller increase, and making apparatus need to use more steel, and operation will consume more
The energy, existing press section of a paper machine in actual use, only uses the working efficiency of single chamber mostly only with a vacuum chamber
It still can further progress optimization.
Utility model content
The purpose of this utility model is to provide a kind of gears to rotate dual chamber suction roller, to solve to mention in above-mentioned background technique
There is still a need for advanced optimize the service efficiency of single chamber out.
To achieve the above object, the utility model provides the following technical solutions: a kind of gear rotation dual chamber suction roller, including
The left and right end inner cavity of roll body, operating device end, gear drive, through-hole, vacuum meter, push wheel, the roll body is fixedly mounted
There is hollow shaft diameter, the operating device end includes grasping outer labyrinth ring, operation side shaft holder, operation inboard bearing lid and passing behaviour inside
Water proof ring, and operating device end is fixedly installed in the outer wall of the hollow diameter of axle, the gear drive include connecting shaft pinion gear and
Gear wheel, the gear wheel are located at the outer wall of the hollow diameter of axle of right part, and the inner cavity of the roll body is respectively arranged with high vacuum case and low
Vacuum tank, the bottom end right part and right end of the hollow diameter of axle described in right part are separately installed with low vacuum suction pipe and high vacuum suction pipe, described
Low vacuum suction pipe and high vacuum suction pipe are connected to low vacuum case and high vacuum case respectively.
Preferably, the connecting shaft pinion gear and gear wheel transmission speed ratio are 2.7.
Preferably, the left part of the hollow diameter of axle described in left part is equipped with worm gear device.
Preferably, the low vacuum suction pipe and high vacuum suction pipe are stainless steel suction pipe.
Compared with prior art, the utility model has the beneficial effects that the present apparatus is by being changed to dual chamber for single chamber suction roller
Suction roller improves drainage effect to form the clearly demarcated gradient pressure difference of pressure, so that the air pressure being conducive in low-voltage vacuum case can
Quick-return low-pressure state during paper constantly passes in and out is saved the time for squeezing out moisture, and then is improved efficiency.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of gear rotation dual chamber suction roller, including roller
The left and right end inner cavity of body 1, operating device end, gear drive 9, through-hole, vacuum meter, push wheel, the roll body 1 is fixedly mounted
There is hollow shaft diameter 3, the operating device end includes grasping outer labyrinth ring 2, operation side shaft holder 4, operation inboard bearing lid 5 and passing behaviour
Inside water proof ring 6, and operating device end is fixedly installed in the outer wall of the hollow diameter of axle 3, the gear drive 9 includes that connecting shaft is small
Gear 91 and gear wheel 92, the gear wheel 92 are located at the outer wall of the hollow diameter of axle 3 of right part, and the inner cavity of the roll body 1 is respectively set
There are high vacuum case 7 and low vacuum case 8, the bottom end right part and right end of the hollow diameter of axle 3 described in right part are separately installed with low vacuum suction pipe
10 and high vacuum suction pipe 11, the low vacuum suction pipe 10 and high vacuum suction pipe 11 connect with low vacuum case 8 and high vacuum case 7 respectively
It is logical.
Wherein, connecting shaft pinion gear 91 and 92 transmission speed ratio of gear wheel are 2.7, and the left part of the hollow diameter of axle 3 of left part is equipped with snail
