The first venthole 431 and the second venthole will not be entered, cabinet is directly discharged by drainage hole 46 and drainpipe 47, in this way may be used
Avoid condensed water as air-flow enters diversion pipe 45 and then takes the caused influence to paper product quality on paper to.
In the present embodiment, wide pressure area curved surface 21 is formed at the cooperation extruding of boot last pressure roller 2 and vacuum pressure roller 1, wide pressure area is bent
There is fit clearance between face 21 and vacuum pressure roller 1.The width of wide pressure area curved surface is set as 25cm~35cm, fit clearance setting
For 8mm~12mm.When paper web is by pressure area between boot last pressure roller 2 and vacuum pressure roller 1, boot last pressure roller 2 and vacuum pressure roller 1 it
Between the wide pressure area curved surface 21 with certain fit clearance is formed in extrusion process from inside to outside, thus the long-time under forming static pressure
Wide pressure area dehydration, can adjust line pressure in wider pressure area, make web moisture profile more evenly, greatly improve squeezing mass dryness fraction, in turn
The bulk and pliability for improving finished paper, reduce the steam consumption of subsequent drying, more energy saving.
When work, l Water Paper is advancing into heating net belt 5 into boot last pressure roller 2, and by steam chest 4 on heating net belt 5
L Water Paper carries out steam heating, so that l Water Paper is first removed portion of water, subsequently enters the pressure between boot last pressure roller 2 and vacuum pressure roller 1
Area forms the long-time width pressure area dehydration under static pressure.Compared with prior art, using above-mentioned hot-air and heating net belt 5 and boots pressure
With the combination squeezing structure of vacuum pressure roller 1, it can make to squeeze mass dryness fraction and improve to 50% or more, and then improve speed and remain good
Bulk, and subsequent drying energy consumption is made to reduce about 30%.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
