Abstract
The invention discloses an energy-saving wide-area squeezing wet section, which comprises a vacuum suction shifting roll, a stone roll, a squeezing roll, a guide roll, a centering roll, a deviation adjusting roll, a tension roll, a coarse cotton cloth washing device and a forming net, wherein every two of the vacuum suction shifting roll, the stone roll and the squeezing roll are tangentially arranged from bottom to top, the squeezing roll is a pneumatic tire roll, the forming net is respectively sleeved among the vacuum suction shifting roll, the guide roll, the deviation adjusting roll and the tension roll, the coarse cotton cloth washing device is also arranged under the forming net, and a pressure area is formed by the vacuum suction shifting roll and the stone roll. The vacuum suction shifting roll and the stone roll form the pressure area, the quantity of original dehydrating elements is greatly reduced, and the structure of the wet section is simplified, so that compared with a traditional structure, not only is the dehydrating effect good, but also the energy consumption of equipment such as a vacuum pump is also minimized, the workshop occupation space is reduced, and the maintenance cost of the equipment is also reduced.
Description
Technical field
The invention belongs to the Wire-cloth structure optimization of paper industry, is exactly to strengthen the net cornerite specifically, and the method for 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 is to rely 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 or leaf is about 18%---22%, the web part of paper machine (as shown in Figure 1) of commonly using now, this scheme does not have nip, the l Water Paper page or leaf is through dewatering plate, wet suction box and suction flat box etc. nearly behind tens the dehydration original paper, further inhales by vacuum after the dehydration through suction couch roll and moves roller and take the l Water Paper page or leaf to press section.The weak point of present this scheme is that the forming table of design is longer, the quantity of dewatering elements is more, the energy consumption of the auxiliary device of dehydration original paper (such as vavuum pump etc.) increases thereupon, so that whole Wire-cloth structure is complicated, not only take the space of plant building, and acquisition expenses is high, has increased the routine use maintenance cost.
Summary of the invention
Purpose of the present invention just is to overcome the Wire-cloth structure that above-mentioned deficiency provides a kind of novel energy-conserving.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of energy-saving wide district squeezing wet end, comprise that the vacuum suction moves roller, stone roll, pressure roller, deflector roll, regulating roller and idler roller, felt cleaner and forming web, vacuum is inhaled and is moved the from bottom to top in twos tangent setting of roller, stone roll and pressure roller, described pressure roller are pneumatic rollers, vacuum is inhaled to move between roller, deflector roll, regulating roller and the idler roller and is arranged with forming web, be arranged with forming web between pressure roller, deflector roll, regulating roller and the idler roller, also be provided with felt cleaner below forming web, vacuum is inhaled and is moved roller and stone roll composition 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, vacuum are inhaled the width that moves roller and are moved roller greater than general vacuum suction.
Above-mentioned energy-saving wide district squeezing wet end, described pneumatic roller is inflatable rubber roll.When stone roll and pneumatic roller formation nip, because low can the generation of glue surface hardness sunk, the contact-making surface of two rollers is widened, become face BC contact by original some A contact, then increased the width of original area, so when improving the roller linear pressure and pressure is constant or reduce, make the l Water Paper page or leaf elongated in the extruded time in the process of overpressure zone, thereby improve the mass dryness fraction of l Water Paper page or leaf.
Adopt technique scheme, wet end of the present invention has strengthened the cornerite of forming web on stone roll, with the pneumatic roller of press roll replacing Cheng Gengkuan, contact-making surface is widened, make the l Water Paper page or leaf elongated in the extruded time in the process of overpressure zone, improve the mass dryness fraction of l Water Paper page or leaf.On the other hand vacuum is inhaled and move roller and stone roll composition nip, not only saved the space, can also shorten the length of wet end, the vacuum suction moves roller two specific true suction sections, when the suction of l Water Paper page or leaf process vacuum moves the extruding of roller and stone roll, move specific two the suction districts of roller by the vacuum suction and the water that squeezes out is siphoned away and the l Water Paper page or leaf is adsorbed on the forming web, bring it to inhale and move the pressure roller place.
Adopt technique scheme, the present invention has following advantage: in the situation that existing paper machine structure is constant, utilize the low characteristic of pneumatic roller glue surface hardness, scientifically stone roll and pneumatic roller are formed nip, change the few difficult problem of traditional mechanical presses dehydration, improved to a great extent the effect of dehydration.

The specific embodiment
The present invention does with detailed description below in conjunction with drawings and Examples:
Such as Fig. 2, Fig. 3 and squeezing wet end in a kind of energy-saving wide district shown in Figure 5, comprise that the vacuum suction moves 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 is inhaled and is moved roller 1, stone roll 2 and pressure roller 3 are in twos tangent setting from bottom to top, described pressure roller 3 are pneumatic rollers, vacuum is inhaled and is moved roller 1, deflector roll 4, be arranged with forming web 8 between regulating roller 5 and the idler roller 6, pressure roller 3, deflector roll 4, be arranged with forming web 8 between regulating roller 5 and the idler roller 6, also be provided with felt cleaner 7 below forming web 8, vacuum is inhaled and is moved roller 1 and stone roll 2 composition nips.The vacuum of this press section of a paper machine is inhaled and is moved roller two specific true suction sections are arranged, i.e. the first true suction section c1 and the second true suction section c2, and stone roll is inhaled to move with vacuum and is consisted of the first nip y1 between the roller, formation the second nip y2 between stone roll and the pressure roller.The diameter of pneumatic roller of the present invention is greater than general pressure roller, and vacuum is inhaled the width that moves roller and moved roller greater than general vacuum suction, and described pneumatic roller is inflatable rubber roll.When stone roll and pneumatic roller formation nip, because low can the generation of glue surface hardness sunk, the contact-making surface of two rollers is widened, become face BC contact by original some A contact, then increased the width of original area, so when improving the roller linear pressure and pressure is constant or reduce, make the l Water Paper page or leaf elongated in the extruded time in the process of overpressure zone, thereby improve the mass dryness fraction of l Water Paper page or leaf.
When wet web when entering into the nip of stone roll and suction couch roll composition through the folder net former, suction couch roll has specific two true suction sections (such as Fig. 3), suction couch roll is after pushing with stone roll, by true suction section c1 the water that squeezes 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, thereby improve the aridity of l Water Paper page or leaf, this design can make the l Water Paper page or leaf bring up to 24 ~ 27% in the aridity of wet end.
