Abstract
The present invention discloses a kind of energy-saving wide district squeezing wet end, comprise vacuum suction roller, stone roll, pressure roller, deflector roll, regulating roller and idler roller, felt cleaner and forming web, vacuum suction roller, stone roll and pressure roller are tangent setting between two from bottom to top, described pressure roller are pneumatic rollers, vacuum suction roller, deflector roll, between regulating roller and idler roller, be arranged with forming web, pressure roller, deflector roll, between regulating roller and idler roller, be arranged with forming web, below forming web, be also provided with felt cleaner, vacuum suction roller and stone roll form nip.This design vacuum suction roller and stone roll being formed nip, original dewatering elements quantity is significantly reduced, Wire-cloth structure simplifies, compared with traditional structure, not only dehydrating effect is good, the energy consumption of the equipment such as selected vavuum pump also drops to minimum thereupon, and take hall space and reduce, the maintenance cost of equipment also reduces.
Description
Technical field
The invention belongs to the Wire-cloth structure optimization of paper industry, be exactly strengthen net cornerite specifically, the method utilizing vacuum and extrusion dehydration to combine improves the mass dryness fraction of wet end wet web, reduces power consumption and the regular maintenance consumption of wet end.
Background technology
The wet end of Present Domestic paper machine mainly relies on gravity and vacuum to realize dehydration.The mass dryness fraction scope that the page of this paper machine goes out wet end l Water Paper page is about 18%---22%, now conventional web part of paper machine (as shown in Figure 1), this scheme does not have nip, l Water Paper page after reaching the dehydration original paper of tens through dewatering plate, wet suction box and suction flat box etc., then takes l Water Paper page to press section by vacuum suction roller after suction couch roll dewaters further.The weak point of current this scheme is that the forming table designed is longer, the quantity of dewatering elements is more, the energy consumption of the auxiliary device (as vavuum pump etc.) of dehydration original paper increases thereupon, make whole Wire-cloth structure complicated, not only take the space of plant building, and acquisition expenses is high, add routine use maintenance cost.
Summary of the invention
Object of the present invention is just to overcome the Wire-cloth structure that above-mentioned deficiency provides a kind of novel energy-conserving.
Object of the present invention realizes by following technical scheme:
A kind of energy-saving wide district squeezing wet end, comprise vacuum suction roller, stone roll, pressure roller, deflector roll, regulating roller and idler roller, felt cleaner and forming web, vacuum suction roller, stone roll and pressure roller are tangent setting between two from bottom to top, described pressure roller are pneumatic rollers, vacuum suction roller, deflector roll, between regulating roller and idler roller, be arranged with forming web, pressure roller, deflector roll, between regulating roller and idler roller, be arranged with forming web, below forming web, be also provided with felt cleaner, vacuum suction roller and stone roll form nip.
Above-mentioned energy-saving wide district squeezing wet end, the diameter of described pneumatic roller is greater than general pressure roller.
Above-mentioned energy-saving wide district squeezing wet end, the width of vacuum suction roller is greater than general vacuum suction roller.
Above-mentioned energy-saving wide district squeezing wet end, described pneumatic roller is inflatable rubber roll.When stone roll and pneumatic roller form nip, can sink because glue surface hardness is low, the contact surface of two rollers is widened, become face BC from original some A contact to contact, then the width of original area is increased, so while raising roller linear pressure, pressure is constant or reduce, and makes l Water Paper page extruded time in the process through overpressure zone elongated, thus improves the mass dryness fraction of l Water Paper page.
Adopt technique scheme, wet end of the present invention increases the cornerite of forming web on stone roll, by the pneumatic roller of press roll replacing Cheng Gengkuan, contact surface between pneumatic roller and stone roll is widened, make l Water Paper page extruded time in the process through overpressure zone elongated, improve the mass dryness fraction of l Water Paper page.On the other hand vacuum suction roller and stone roll are formed nip, not only save space, the length of wet end can also be shortened, vacuum suction roller has two specific true suction sections, when l Water Paper page is through the extruding of vacuum suction roller and stone roll, by the specific Liang Gexi district of vacuum suction roller the water squeezed out siphoned away and l Water Paper page is adsorbed on forming web, bringing it to and aspirate pressure roller place.
Adopt technique scheme, the present invention has following advantage: when existing paper machine structure is constant, utilizes the characteristic that pneumatic roller glue surface hardness is low, scientifically stone roll and pneumatic roller are formed nip, change the difficult problem that traditional mechanical extrusion dehydration is few, greatly enhance the effect of dehydration.

Detailed description of the invention
The present invention does below in conjunction with drawings and Examples with detailed description:
As Fig. 2, a kind of energy-saving wide district squeezing wet end shown in Fig. 3 and Fig. 5, comprise vacuum suction roller 1, stone roll 2, pressure roller 3, deflector roll 4, regulating roller 5 and idler roller 6, felt cleaner 7 and forming web 8, vacuum suction roller 1, stone roll 2 and pressure roller 3 are tangent setting between two from bottom to top, described pressure roller 3 are pneumatic rollers, vacuum suction roller 1, deflector roll 4, forming web 8 is arranged with between regulating roller 5 and idler roller 6, pressure roller 3, deflector roll 4, forming web 8 is arranged with between regulating roller 5 and idler roller 6, felt cleaner 7 is also provided with below forming web 8, vacuum suction roller 1 and stone roll 2 form nip.The vacuum suction roller of this press section of a paper machine has two specific true suction sections, and namely the true suction section c2 of the first true suction section c1 and second, forms the first nip y1, form the second nip y2 between stone roll and pressure roller between stone roll and vacuum suction roller.The diameter of pneumatic roller of the present invention is greater than general pressure roller, and the width of vacuum suction roller is greater than general vacuum suction roller, and described pneumatic roller is inflatable rubber roll.When stone roll and pneumatic roller form nip, can sink because glue surface hardness is low, the contact surface of two rollers is widened, become face BC from original some A contact to contact, then the width of original area is increased, so while raising roller linear pressure, pressure is constant or reduce, and makes l Water Paper page extruded time in the process through overpressure zone elongated, thus improves the mass dryness fraction of l Water Paper page.
When wet web is entering into stone roll and suction couch roll and forms nip through folder net former, suction couch roll has specific two true suction sections (as Fig. 3), suction couch roll is after extruding with stone roll, by true suction section c1, the water squeezed out is siphoned away, and make paper web be adsorbed on wire side, carry it into the true suction section c2 of suction couch roll, thus improve the aridity of l Water Paper page, this design can make l Water Paper page bring up to 24 ~ 27% in the aridity of wet end.
