Abstract
The utility model provides an one presses upward roller dehydration scraper device, press including one and go up roller, scraper and the surperficial water ring of roller on presses, the scraper is located a pressure just is close to in the position of paper export on going up the roller. The utility model discloses an increasing the dehydration scraper on the roller on one presses, getting rid of the roll surface water ring, promote the mass dryness fraction that the page goes out a pressure, increase the page and get into dryer part intensity, reduce disconnected paper, reduce the steam consumption, reduction in production cost increases economic benefits.
Description
Technical field
This utility model relates to a kind of paper making equipment, particularly relates to a kind of one and presses roller dehydration device.
Background technology
In recent years, in paper-making process, produce progressively stable, production capacity and promote, speed has been promoted to 800 ms/min, but along with the lifting of speed, page goes out press section mass dryness fraction and is unable to reach optimum state, mainly due to a press-dehydrating difficulty, especially one press roll-in water outlet and form water ring at roll surface, removing not fall, affect the mass dryness fraction of page, causing into paper, to go out press section mass dryness fraction too low, steam consumption increases, and cadre's web strength fragility causes that disconnected paper is more.And then have impact on into the quality of paper.
China's utility model (201020118194.2: the dehydration device of paper machine) discloses the dehydration device of a kind of paper machine, it mainly includes a pressure roller group being coordinated transmission from upper supporting roller with snub pulley, one carries out dehydration with the felt of l Water Paper page through this pressure roller group on it, it is characterized in that: also include a high-order dancer rools, l Water Paper page first through this high position dancer rools then through pressure roller group, and this high position dancer rools is higher than upper supporting roller setting.
Above-mentioned utility model is by adding a high-order dancer rools, forming the previously extruded dehydration to the l Water Paper page before press dewatering, make the dewatering efficiency of pressure roller group promote further between this high position dancer rools and upper supporting roller；But page goes out the mass dryness fraction of press section and reaches optimum state in the process of dehydration it cannot be guaranteed that after dehydration, paper overdrying after dehydration or overly moist all can affect the quality of paper.It is indeterminable for this problem in above-mentioned utility model.
Utility model content
For problems of the prior art, this utility model presses roller one increases a set of dehydration doctor blade device, removes roll surface water ring, promotes page and goes out a degree of pressing dry, and increases page and enters drying section intensity.
For realizing above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of one presses roller dehydration doctor blade device, including scraper, one presses roller body and is formed at a water ring pressing roller surface；Scraper is located at described one and is pressed on roller, and close to the position of paper outlet.
Preferably, water ring is cut off by described scraper in paper outlet position.
Compared with prior art, this utility model produces to provide the benefit that:
(1) improve into paper paper web and go out press section mass dryness fraction, add page and enter the intensity of drying section, improve the stability of paper machine operation；
(2) become paper paper web mass dryness fraction to promote, reduce the disconnected paper probability of drying section, promote time efficiency；
(3) paper web mass dryness fraction promotes, and reduces steam consumption, reduces production cost, adds economic benefit.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below the accompanying drawing used required during the present embodiment is described is briefly described, apparent, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is of the present utility model one structural representation pressing roller dehydration doctor blade device.
Wherein, roller is pressed at 1: one；2: scraper；3: water ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining.
Shown in ginseng Fig. 1, this utility model one one presses roller dehydration doctor blade device, including: one presses roller 1, scraper 2 and water ring 3.Water ring 3 is formed at a surface pressing roller, and scraper 2 is located at one and is pressed on roller, and close to the position of paper outlet；Water ring is cut off by scraper 2 at paper outlet place, removes the water ring of roll surface；When paper enter into one press roller after, scraper quits work, until paper output, thus can promote page and go out the mass dryness fraction of a pressure, enhances page and enters the intensity of drying section, reduces disconnected paper phenomenon.
A series of detailed description mentioned above is only for illustrating of feasibility embodiment of the present utility model; they limit protection domain of the present utility model; in the ken that described technical field those of ordinary skill possesses, the various changes made under the premise without departing from this utility model objective belong to protection domain of the present utility model.
Below for a certain production line, within 9 months one, press before contrasting 2014 roller increase after doctor blade device with the steam consumption data same period in 2013, evaluate the economic benefit brought after this utility model increases doctor blade device.
(1) contrast within 9 months one, pressed before 2014 roller increase after doctor blade device with the steam consumption data same period in 2013, as shown in table 1.
Table 1
The average ton paper steam mono-consumption 1.984 tons of 9 months before can being drawn 2013 by table 1, and 2014 9 months ton paper unit consumption are 1.883 tons, ton paper steam mono-consumption reduces by 0.101 ton.
In Jan-Sept, 2014, papermaking yield is 184037 tons, and steam price presses 95 yuan/ton of calculating, and in Jan-Sept, 2013 steam saving fund is on year-on-year basis:
184037*0.101*95=176.6 ten thousand yuan.
6 months steam saving expenses of average computation are: 176.6/9*6=117.7 ten thousand yuan.
(2) contrast within 9 months one, pressed before 2014 roller increase after doctor blade device with the yield data same period in 2013, as shown in table 2.
Table 2
Before can being drawn 2013 by table 2,9 months total outputs are 179835 tons, and the same period in 2014, yield was 184037 tons, exceeded 184037-179835=4202 ton on year-on-year basis, if ton paper net profit can be calculated by 200 yuan:
Within first 9 months, have more pure benefit: 4202*200=84.04 ten thousand yuan；
Amounting to into 6 months pure benefits is: 84.04/9*6=56 ten thousand yuan.
Therefore, the one one that this utility model provides presses roller dehydration doctor blade device, removes roll surface water ring, promotes paper and goes out a degree of pressing dry, and increases page and enters the intensity of drying section, reduces disconnected paper, reduces steam consumption, reduce production cost, increases economic benefit.
