Abstract
The utility model discloses a kind of suction press roll, including vacuum lumen, body layer and liners, the body layer and the liners are provided with connected through hole, through hole side inwall is provided with adjustable plate and limited block, the adjustable plate base is flexibly connected with the through-hole wall, when the connected inwall of adjustable plate is bonded, top protrudes the through hole, and the limited block is used to limit the adjustable plate anglec of rotation.The utility model has the adjustable function of hole size.
Description
Technical field
A kind of suction press roll is the utility model is related to, belongs to pressure roller technical field.
Background technology
The major function of paper machine press section is dehydration, solidification page, while improves page characteristic, and it is strong to improve wet web
Spend to improve the drying capacity of drying section.Suction press roll is to realize the key equipment of press section major function.The master of vacuum furnace
It is to have the less through hole of many diameters on roller shell to want feature, and through hole is by liners and body layer, and roller shell inner chamber maintains during work
Continuous vacuum.When page and woollen blanket enter the nip of pressure roller and suction press roll, the water in page is transferred to woollen blanket, when in woollen blanket
Water saturation when, under pull of vacuum effect, water is discharged from woollen blanket, into through hole, is discharged after importing roller shell inner chamber.
Improve paper machine speed, it is desirable to which the dewatering efficiency of press section of a paper machine is higher.One of method is to improve nip
Line pressure.The line pressure of nip is bigger, and page dehydration is more, but because page may can not be too big by conquassation, line pressure.And line
Pressure is bigger, and the frame of press section and the rigidity increase of roller, making apparatus need to use more steel, and operation will consume more energy
Source.Still an alternative is that improving the water separation capability of vacuum furnace, the water separation capability for improving vacuum furnace can be by increasing on roller shell
The quantity of through hole realizes, because through hole by liners and body layer, too much perforate influences whether the overall strong of vacuum furnace
Degree, influences the raising of line pressure in turn, and the water separation capability of vacuum furnace is not greatly improved, has influence on press section and be integrally dehydrated energy
Power, govern the raising of paper machine speed.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of suction press roll that can adjust hole size.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of suction press roll, including vacuum lumen, body layer and liners, the body layer and the liners
Be provided with connected through hole, through hole side inwall is provided with adjustable plate and limited block, the adjustable plate base with it is described
Through-hole wall is flexibly connected, and when the connected inwall of adjustable plate is bonded, top protrudes the through hole, and the limited block is used
In the restriction adjustable plate anglec of rotation.
The limited block is symmetricly set on both sides on the inside of the via top edge.
The limited block is located at the via top radial distance away from the place of adjustable plate 1/3 to 1/2.
The adjustable plate is highly the adjustable plate tie point and the limited block line distance.
The adjustable plate bottom junctions are located at the via depth more than 1/2.
The adjustable plate is provided with the resetting means for being used to make the adjustable plate be bonded the through-hole wall.
The through hole section is square.
The beneficial effect that the utility model is reached：Using the combination settings of adjustable plate and limited block, can squeeze
When roller enters nip, limiting plate movement is driven, reduces through hole bore, improve line pressure, and then improve water separation capability, leave nip
Afterwards, homing and raising through hole bore, drainability can be improved, and then strengthen follow-up dehydration under resetting means effect
Ability.
Brief description of the drawings
Fig. 1 is the utility model section view；
Fig. 2 is the top view of the utility model different shape through hole.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating this
The technical scheme of utility model, and the scope of protection of the utility model can not be limited with this.
Such as Fig. 1, shown in Fig. 2, a kind of suction press roll, including vacuum lumen, body layer and liners, the body layer
And the liners is provided with connected through hole 1, the side inwall of through hole 1 is provided with adjustable plate 2 and limited block 3, institute
State the base of adjustable plate 2 to be flexibly connected with the inwall of through hole 1, when the 2 connected inwall of adjustable plate is bonded, top protrudes
The through hole 1, the limited block 3 are symmetricly set on both sides on the inside of the top edge of through hole 1, and the limited block 3 is positioned at described
1/3 to 1/2 place of the top radial distance of through hole 1 away from the adjustable plate 2, the height of adjustable plate 2 are that the adjustable plate 2 connects
Point and the limited block line distance, bottom junctions are located at the depth more than 1/2 of through hole 1, and the adjustable plate 2, which is provided with, to be used
In the resetting means for making the adjustable plate 2 be bonded the inwall of through hole 1, flexure strip, spring etc., the section of through hole 1 can be made
It is preferably square, it during using other shapes, can coordinate with limited block, limited block is arranged to suitable spacing swash plate, or
Adjustable plate 2 is arranged to arc, bending plate etc., coordinates the reduction for realizing through hole bore.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and deformation can also be made, these change
Enter and deform and also should be regarded as the scope of protection of the utility model.
