Description
Technical field
The present invention relates to papermaking equipment technical field, specially one kind is vacuum formed roller.
Background technology
One of vacuum furnace, papermaking equipment composition, positioned at wet end end.Vacuum furnace is widely used in the wet end and pressure of paper machine
Squeezing portion, vacuum roller arrangement is the critical elements of wet end dehydration, and the quality of wet end dehydration is directly connected to the height of production cost.
Because vacuum furnace is, so as to which the moisture content in page is extracted, so to cause unavoidably on roll body by vacuumizing
Some moisture content is also remained, along with paper machine runs at high speed, due to the effect of centrifugal force, a part of moisture content remained on roll body
It will be thrown on felt, causing the water content of felt increases, and page detachment is poor, and the moisture content in page also rises therewith, page
Drying consumption also correspondingly increase, existing vacuum furnace is complicated, and cost is high, it is impossible to meet user's demand, nothing
The absorption affinity of the dispersed vacuum roller surface of method, the problem of suction couch roll is due to local scratch often being occurred by material impact, such as
The local damage of roll surface, roll body inwall are scratched, roll body two ends pneumatic tyre position is worn and torn etc.；The transmission portion abrasion of roll body is another kind of
The position abrasion of the failure often occurred, such as suction couch roll bearing, journal wear, keyway damage lamp, Traditional solutions with repair welding or
Based on brush plating, but the thermal stress that high temperature is produced during repair welding can not be completely eliminated, and Brush Plating is limited by coating layer thickness, easily stripping
Fall.
The content of the invention
Roller is vacuum formed it is an object of the invention to provide one kind, to solve the existing knot proposed in above-mentioned background technology
Structure is complicated, and cost is high, and dewatering is poor, it is impossible to the absorption affinity of dispersed vacuum roller surface, weares and teares more tight in use
The problem of weight.
To achieve the above object, the present invention provides following technical scheme：One kind is vacuum formed roller, including pressure gauge, exhaust
Mouth, suction inlet, vavuum pump, rotation connecting shaft, filter layer, vacuum drainpipe, rubber layer device, vacuum pressure roller and bearing mounting base
Device, the manometric right-hand member is fixedly installed exhaust outlet, and its upper right side is installed with suction inlet, the pressure gauge with
The inside of vavuum pump is connected, and the rotation connecting shaft is fixedly connected with vacuum drainpipe, and the upper end of vacuum drainpipe is fixed
Filter layer is mounted with, the top of the vacuum pressure roller is provided with rubber layer device, and its right-hand member is fixedly installed bearing mounting base dress
Put, led to repeatedly by pipeline between the vavuum pump and vacuum pressure roller, the vavuum pump is internally provided with pressure sensitive device,
The vacuum drainpipe is connected with the inside of externally drained equipment, eyelet a diameter of 3-4mm on the vacuum pressure roller, described
Vacuum pressure roller is detachable device with filter layer.
Compared with prior art, the beneficial effects of the invention are as follows：This is vacuum formed roll structure simply, and cost is relatively low,
Roller shell is high duty metal material, wear-resisting ageing-resistant, is hardly damaged in use, can be with the absorption of dispersed vacuum roller surface
Power, with preferable adhesion strength and compression strength, while oil resistant corrosion resistance that the coating of vacuum furnace has in itself and self-lubricating
Function, it is ensured that roll body rub proofness, it is to avoid the problem of degree of wear of roller is too fast, during high speed copy paper, woollen blanket and l Water Paper
After moisture is sucked out, by eyelet on roller, almost has little time to reach vacuum dehydration area is just turned in vacuum chamber, then by roller
Centrifugal force be thrown into white wate tray, roller shell is thicker, aspirate air volume it is more, be conducive to improve dewatering efficiency.On vacuum pressure roller
The axial and circumferential centre distance of eyelet is smaller, and eyelet number is more, can significantly improve the dehydration of vacuum pressure roller.
