Description
Technical field
The present invention relates to the technical field of paper making equipment, specifically a kind of high speed paper machine, particularly its mechanical connecting structure.
Background technology
Documents, the patent No.: 200980136442.6, the applying date: 2009.09.16, patentee: Metso Pei Pokaersitade company, this case discloses a kind of " method of tissue machine and manufacture tissue paper web ", and this tissue machine comprises: the wet end that is used to form fibrous web; For squeezing the press section of described fibrous web, described press section comprises: single squeezer, and this squeezer comprises: the first pressing part; The second pressing part, forms the press. nips with predetermined pressure between described pressing part; Press felt, described press felt contacts and moves with loop checking installation by described press. nips and with this fibrous web around a plurality of deflector rolls and together with the described fibrous web forming, and described the second pressing part is arranged on the inner side in the loop of described press felt; Smooth zone, this smooth zone contacts and moves with loop checking installation by described press. nips and with this fibrous web around a plurality of deflector rolls and together with the described fibrous web forming, and described the first pressing part is arranged on the inner side in described Dai loop; And transfer roller, this transfer roller is arranged on the inner side in the loop of described smooth zone; Drying section, this drying section is finally dried for the fibrous web to after squeezing in described press. nips, and described drying section comprises for the fibrous web to after described squeezing and carries out final dry desiccated surface; Described transfer roller is set to form transmission nip together with described desiccated surface, for described fibrous web is sent to described desiccated surface, wherein said smooth zone is set to transport the fibrous web after described squeezing between described press. nips and described transmission nip, this tissue machine is characterised in that: the provided upstream at described squeezer is equipped with pre-dehydration device, to enter in the operation of described fibrous web before the described press. nips of described squeezer described fibrous web predrainage to the mass dryness fraction that is preferably 15-30%; And described press felt and described smooth zone be set to after leaving described press. nips immediately separated from one another and define therebetween Jiaoα，Gai angle α at least 5 ° moistening again to prevent the fibrous web after described squeezing.
From above, during the operation of the head box of existing general paper machine, it can not be adjusted the intensity in length and breadth of page, cannot meet the requirement of strength of the various occasions in market to finished product paper.If there is just needs replacing in time of excessive wear in paper machine woollen blanket in running simultaneously, because woollen blanket is pressed on rod lower side, need driving that the rod of a ton of weighing is promoted to rear replaceable, whole process wastes time and energy, and has affected the production efficiency of paper machine.
Because paper machine is in processing paper process, page need to be dried, when paper industry is dried, can produce a large amount of steam.Because page and Yankee cylinder are initial, contact to leaving, the degree of saturation of its water vapour is different.During initial contact, its water vapour contains saturated vapor, very moist, can not reuse, and the steam quality of after-stage is higher, can substantially reclaim.And the humidity discharging moist steam device of existing paper machine is conventionally too complicated, complete equipment cost is high, maintenance is inconvenient, or a simple equipment is only installed, humid air is discharged, steam for former and later two stages is not done differentiated treatment, waste a large amount of dry steams, be unfavorable for energy-saving and emission-reduction.Finally, high-speed broad-width toilet paper goes out Yankee cylinder, need carry out with creping doctor.After a period of time used, blade is all over the blunt blade that more renews of needing.Because blade is wider; need 2 people to operate just simultaneously and can complete tool changing work; the old cutter of whole extraction; insert about one minute consuming time of the process need of new cutter; for high-speed paper machine; running speed per second will reach 20 ms/min, shuts down the time of one minute, paper output that will loss one km.
Summary of the invention
The object of the present invention is to provide a kind of improved paper machine, the head box that it can overcome paper machine in prior art is to adjust to the intensity in length and breadth of page, the woollen blanket of paper machine is difficult for the drying section of replacing, paper machine and will not recycles dry steam, paper machine scraper is replaced and is difficult for simultaneously, the some shortcomings that waste time and energy.
To achieve these goals, technical scheme of the present invention is: a kind of high speed paper machine, it mainly comprise pedestal and be successively set on forming part on pedestal,
press section, drying section and wrinkling portion, it is characterized in that: forming part is provided with paper forming machine structure and head box guiding mechanism,
press sectionbe provided with paper dewatering mechanism and roller hoisting mechanism, drying section is provided with humidity discharging moist steam device, and wrinkling portion is provided with doctor assemblies and paper winder.
During use, paper pulp sprays by head box, forms l Water Paper page between the forming web above format roll and woollen blanket, by the effect of format roll centrifugal force, dewaters, page after dehydration, along with woollen blanket runs between vacuum carrying roller and Yankee cylinder, further carries out high line pressure high temperature dehydration.Page by the creping doctor on Yankee cylinder, is peeled off from Yankee cylinder, and then runs to reel machine and carry out coil paper, thereby completes from paper pulp to the process that becomes paper.
Owing to being provided with head box guiding mechanism in forming part, by the adjusting of head box spray angle, control slurry Luo Jiangdian position, thereby be embodied as the paper requirement of different tension intensity performances in length and breadth.Press section is provided with roller hoisting mechanism, when needs are more during felt changing, and rotating nut, roller is just raised, and reserves behind space, and woollen blanket is just easy to change.Whole mechanism operation is easy, and efficiency is higher, can promote a plurality of rollers, the restriction of not driven a vehicle simultaneously.Drying section is provided with humidity discharging moist steam device, the very moist water vapour producing when page initially can be contacted with Yankee cylinder is separated with gas hood, by gland steam exhauster, emit, when page advances to after-stage, the steam quality in gas hood is higher again, can directly recycle, the simple structure of this use is very effective by the method for water vapour differentiated treatment, can greatly improve energy-saving effect, and apparatus structure is simple, cost is lower, for ease of maintenaince and maintenance.Wrinkling portion is provided with allowing blade replacement device, and whole exchanging knives process only needs one man operation to complete, and simultaneously tool change time is original 1/4th, has greatly improved the efficiency of allowing blade replacement, has reduced labour intensity, has improved production efficiency.
