Description
Technical field
The utility model belongs to pulping and paper-making equipment and technical field, is specifically related to a kind of paper machine forming section.
Background technology
The main effect of wire-cloths is that material is retained on the net as far as possible, more deviate from moisture and forms the wet web of full uniformity.Paper stock should evenly disperse on the net, make the full width page quantitatively, uniformities such as thickness, evenness, and possess certain intensity, so that wet web is introduced press section.Tradition paper sheet formation and dehydration generally comprise the network segment, shaping dewatering period, High Pressure Difference dewatering period, make page reach certain requirement in the mass dryness fraction of leaving wet end.Dehydration and shaping are simultaneous, are guaranteeing under the quality prerequisite that is shaped, fast as far as possible dehydration.Modern Paper Machine is along with the improve of the speed of a motor vehicle; For dewatering speed require increasingly highly, tightly can not influence the quality of shaping like this, comprise that the two sides difference is big, evenness is poor, cross direction profiles is uneven first-class; Also can increase the length of wet end, cause the increase of inconvenient operation and investment.
The utility model content
The purpose of the utility model is to change the structure of wet end and the layout of dewatering elements, to improve the restriction of wet end for paper machine speed, the paper machine can be moved under the high speed of a motor vehicle, and obtains good paper industry quality.
The utility model comprises fixedly top net, breast roll, wite roll, abdomen roller, head box and spacer screen; The top screen cloth is set to the form of endless loop and moves around said wite roll; Spacer screen is arranged to move around said breast roll, wite roll and abdomen roller with the form of endless loop; And top net and spacer screen form shaping area between abdomen roller and breast roll, and the head box outlet is in the tapered region between top net and spacer screen, and forming part also includes the vacuum tank of arranging along spacer screen; The profiled sheeting case that comprises the below that is installed in spacer screen in the said shaping area A loads scraper and the suction box of the reversal of the natural order of things corresponding with loading doctor position.
Before and after the abdomen roller in the utility model vacuum tank is arranged all, be connected with extraneous vacuum line, the forming board case comprises forming board and Wiper blade; Contact shaping wire side is a cambered surface, and there is the connector of vacuum pipe the side, links to each other with extraneous blower fan; Load scraper inside air bag is installed, be connected with compressed air.
Forming board case, loading scraper, suction box, vacuum tank and top net, spacer screen contact-making surface are equipped with ceramic Wiper blade material.
The utility model has following advantage: the slurry of head box ejection flows directly to get into goes up off line folder district, has eliminated the paper pulp Free Surface that causes occurring irregular slurry stream, has avoided owing to the restriction of Free Surface to the speed of a motor vehicle; The adjustment of the position of dewatering elements makes slurry accelerate in the shaping of wet end, and head box is starched at high-strength microturbulent motion state and just is shaped rapidly before the complete attenuation, has avoided curring time long and phenomenon that fiber that occur is wadded a quilt with cotton again and gathered has improved forming quality; Dewatering time is accelerated, and has improved production capacity; The active force that loads scraper makes the dehydration version apply lasting, stable fluctuation pressure to the net in the high-speed cruising through pneumatic mode control, makes water separation capability reduce the loss of fiber and filler along the mild increase of the direction of network operation; Being shaped, it is short to distinguish, compact conformation, and moving component quantity is few, occupies little space, and the construction investment expense reduces.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explanation:
Fig. 1 is the sketch map of the duty of the utility model;
Fig. 2 is the sketch map of the duty of loading scraper and profiled sheeting case in the utility model.
The specific embodiment
The utility model comprises fixing top net 8, breast roll 2, wite roll 11, abdomen roller 19, head box 1 and spacer screen 9; Top net 8 is arranged to move around said wite roll 11 with the form of endless loop; Spacer screen 9 is arranged to the form of endless loop around said breast roll 2, wite roll 11 and 19 operations of abdomen roller; And top net 8 and spacer screen 9 form shaping area A between abdomen roller 19 and breast roll 2, and head box 1 outlet is in the tapered region of 9 of top net 8 and spacer screens, and forming part A also includes along the vacuum tank 6 of spacer screen 9 layouts; The profiled sheeting case 3 that comprises the below that is installed in spacer screen 9 in the said shaping area A loads scraper 4 and the suction box 5 of the reversal of the natural order of things corresponding with loading scraper 4 positions.
All there is vacuum tank 6 abdomen roller 19 front and back in the utility model, are connected with extraneous vacuum line, and forming board case 3 comprises forming board and Wiper blade, and contact shaping wire side is a cambered surface, and there is the connector of vacuum pipe the side, links to each other with extraneous blower fan.Load scraper 4 inside air bag is installed, be connected with compressed air.Forming board case 3, loading scraper 4, suction box 5, vacuum tank 6 are equipped with ceramic Wiper blade material with top net 8, spacer screen 9 contact-making surfaces.
During work; Fibrous suspension is ejected into the tapered region that top net 8 and spacer screen 9 form by head box 1; Top net 8 runs up with spacer screen 9 fibrous suspension is taken away entering forming board case 3, under vacuum, Wiper blade, net tension force, own wt effect, begins a large amount of dehydrations.Hang upside down suction box 5 progressively dehydration under the effect of different vacuum then, loading scraper 4 increases certain pressure fluctuation, and the paper industry middle level slurry of as far as possible avoiding still being in suspended state is wadded a quilt with cotton again and gathered.The fluctuation pressure that the loading scraper acts on wet end is that this pressure fluctuation not only can improve the wet end water separation capability along on the direction of wet end operation, also can make the more even distribution of fiber in the l Water Paper industry.The adjusting of fluctuation pressure is to realize through regulating gasbag pressure.Vacuum tank 6 further already dewaters to paper under higher vacuum action the moisture that gets into abdomen roller 19 is further reduced.Inhale the net 8 from the top through vacuum abdomen roller 19 behind the paper industry preliminarily forming, be close to spacer screen 9 and get into vacuum tank 6, web dryness reaches 17-22%, gets into next process then.
