Abstract
The utility model relates to papermaking equipment, and provides a press unit of a paper machine. With the press unit, dryness of top-grade, high-quality and multispecies cultural paper is effectively increased, and production efficiency is improved. The press unit comprises a suction transfer roll, a suction press roll, a central stone roll, three grooved press rolls, press felts, a plurality of guide rolls, a stone roll with a large roll diameter, a rubber roll with a large roll diameter and a transfer roll. A five-roll three-press zone is formed by the suction transfer roll, the suction press roll, the central stone roll, the grooved press rolls, the press felts and the guide rolls. A rear press zone comprises the transfer roll, the stone roll with a large roll diameter, the rubber roll with a large roll diameter, the press felt and the guide rolls, and is arranged at a paper web outlet of the five-roll three-press zone. The transfer roll is arranged at the paper web outlet of the five-roll three-press zone. Each grooved press roll is provided with a water bucket.
Description
Technical field
The utility model relates to paper making equipment, particularly a kind of press section of paper machine.
Background technology
Along with present paper machine press section is commonly referred to as five roller three nips, be that paper web moves roller strap to press felt by the vacuum suction, by carried out the first squeezing by suction press roll and grooved press roller, under the vacuum action of vacuum pressure roller, paper web is attached on press felt and continues the unipress that forms by other two grooved press rollers and center stone roll, then enters oven dry section.Because paper web is only pressed through five rollers three, thereby it is larger to enter the paper web moisture of oven dry section, and the press section operational efficiency is not high, causes the paper web drying time long, affects production efficiency.
Summary of the invention
Therefore, for above-mentioned problem, the press section of the paper machine of the utility model proposes the high-grade high-quality of a kind of effective raising and many kinds cultural paper mass dryness fraction, enhancing productivity.
for solving this technical problem, the utility model is taked following scheme: a kind of press section of paper machine, comprise that the vacuum suction moves roller, suction press roll, the center stone roll, 3 grooved press rollers, press felt and a plurality of deflector roll, described vacuum is inhaled and is moved roller, suction press roll, the center stone roll, 3 grooved press rollers, press felt and a plurality of deflector roll consist of five roller three nips, also comprise big roller footpath stone roll, big roller footpath rubber roll and suction move roller, the paper web exit of described five roller three nips is provided with by suction moves roller, big roller footpath stone roll, large footpath roller rubber roll, the rear nip that press felt and a plurality of deflector roll consist of, described suction moves the paper web exit that roller is located at five roller three nips, be equipped with the water receiving bailing bucket on described each grooved press roller.
Further, be positioned on described rear nip to inhale and move the roller rear portion and be provided with air-suction trunk.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: by nip after setting up after former five roller three nips, further get rid of the moisture content of paper web, effectively improve high-grade high-quality and many kinds cultural paper mass dryness fraction, enhance productivity, simultaneously, be provided with air-suction trunk squeezing the front portion, got rid of the air between paper web and press felt, can eliminate the problem of curling round the roll, greatly improve production efficiency, can extensively promote the use of.
Description of drawings
Fig. 1 is the structural representation of cutting open of the utility model embodiment.
The specific embodiment
Now with the specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
with reference to figure 1, the press section of preferred a kind of paper machine of the present utility model, comprise that the vacuum suction moves roller 1, suction press roll 2, center stone roll 3, grooved press roller 4, 5, 6, press felt 7, 8, 9, 10, a plurality of deflector rolls 11, suction moves roller 12, big roller footpath stone roll 13 and big roller footpath rubber roll 14, described vacuum is inhaled and is moved roller 1, suction press roll 2, center stone roll 3, grooved press roller 4, 5, 6, press felt 7, 8, 9, a plurality of deflector rolls 11 consist of five roller three nips, the paper web exit of described five roller three nips is provided with by suction moves roller 12, big roller footpath stone roll 13, large footpath roller rubber roll 14, the rear nip that press felt 10 and a plurality of deflector roll 11 consist of, described suction moves the paper web exit that roller 12 is located at five roller three nips, described 3 grooved press rollers 4, 5, be respectively equipped with water receiving bailing bucket 15 on 6, 16, 17, be positioned on described rear nip to inhale and move roller 12 rear portions and be provided with air-suction trunk 18.
The utility model is by nip after setting up after former five roller three nips, further get rid of the moisture content of paper web, effectively improve high-grade high-quality and many kinds cultural paper mass dryness fraction, enhance productivity, simultaneously, the squeezing front portion be provided with air-suction trunk, got rid of the air between paper web and press felt, can eliminate the problem of curling round the roll, greatly improved production efficiency, can extensively promote the use of.
Although specifically show and introduce the utility model in conjunction with preferred embodiment; but one of ordinary skill in the art should be understood that; within not breaking away from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
