Description of the drawings
Fig. 1 is the equipment connection diagram of the present invention.
Specific embodiment
As shown in Figure 1, a kind of preparation facilities of recycled writing paper, pulper 1 are connected with sieve 10, head box 11, fourdrinier wire wire side 12, squeezer 13 and drier 14 before impurity separator 2, HC Cleaner 3, defibrator 4, outer-flowing type pressure slotted screen 5, low dense desander 6, many disk thickeners 7, fiberizer 8, high-order regulating box 9, net successively by pipeline.
Defibrator 4 includes a section fibre seperator and two section fibre seperators.
Low dense desander 6 includes three sections low dense desanders.
Squeezer 13 includes the big roller blind press of suction couch roll and two roads.
5 tailings end of outer-flowing type pressure slotted screen is connected with two sections of outer-flowing type pressure slotted screens by pipeline.
Before net, the 10 screenings ports of export of sieve are connected with pressurized screen by pipeline.
Described defibrator 4, the machine first half enter latter half of through sieve plate equivalent to horizontal hydraulic pulper, accepted stock, and light impurity is gathered in center low-pressure area and discharges, and heavy seeds are sunken to bottom and periodically discharge, and the machine is latter half of to be sieved equivalent to Horizontal pressure.
Described defibrator 4 is dissociated, screening function in one, sieve plate is hole sizer, and aperture φ 4mm, screen cylinder are slotted screen, and screen slot is 0.4mm.
Specifically used method：
Waste paper pulping production line is mainly by pulping, highly concentrated desanding, coarse sizing, low dense desanding, fine screen is selected, washing concentrating, the operations such as beating composition, from the paper bag that material storage yard is shipped, using front, Jing manually cuts off packing iron wire with pliers and chooses bulk plastic class rubbish, AOCC and LOCC is shifted onto in 48% and 52% ratio forklift respectively and deliver on chain scraper conveyor D type hydrabrushers, with about 3.5% concentration pulping, various prehensile impurity, such as iron wire, rope, plastics, cotton yarn is in rotary course, it is wound a strand to be pulled straight by strander, drain, slurry is made to obtain preliminary purification.
Thick weight debris during pulper size degradation are gathered in sediment well, slurry overflow containing a large amount of lightweights and a small amount of heavy enters impurity separator, in the presence of its rotor, the good stock tank of pulper is entered by the good slurry of sieve plate, thick debris are trapped in impurity separator, discharge after Jing periodic flushing force feed to the dehydration of garden shaft screen, the configuration of this system refines debris during can avoiding pulping, mitigate follow-up equipment load, improve the production capacity of pulper, slurry Jing after size degradation is with about 2.2% concentration by being pumped into HC Cleaner, remove the various heavy seeds in slurry, such as iron nail, glass etc., slurry is entered with the pressure tangential direction of 0.35Mpa, it is purified using vortex centrifugal principle.
Purification disposed slurry enters defibrator with the pressure of 0.15Mpa or so, the machine first half is equivalent to horizontal hydraulic pulper, the larger scraps of paper obtain further size degradation here, accepted stock enters latter half of through sieve plate, and light impurity is gathered in center low-pressure area and discharges, and heavy seeds are sunken to bottom and periodically discharge, the machine is latter half of to be sieved equivalent to Horizontal pressure, qualified slurry enters reserve pit, the tailings of defibrator, by being pumped into two section fibre seperators after screen cylinder；, in one, one-machine-multi-function, the design sieve plate are hole sizer, and aperture φ 4mm, screen cylinder are slotted screen, and screen slot is 0.4mm for defibrator dissociation, screening function；The light impurity and tail slurry of defibrator is pumped into two section fibre seperators with 2.5% concentration；The good slurry of two section fibre seperators is incorporated to the good stock tank of a section fibre seperator, and the light impurity and tail slurry Jing frame plansifter that shakes further is screened；The good slurry of frame plansifter of shaking is sent to scalping system, and screenings is drained；Whole coarse sizing system significantly reduces the fibre weight being lost in deslagging.The hydrabrusher waste paper rate of dissociation about 70%, can make the rate of dissociation bring up to 90% from two section fibre seperator systems.
Outer-flowing type pressure slotted screen is subsequently set, fine screen is carried out to slurry；Slotted screen works under low dense state, can save energy consumption.Working concentration about 0.8～1.5%, the sieve enters slurry mode for bottom, bottom discharge is deposited to after heavy seeds access arrangement, the excessive wear to screen cylinder and rotor and the blocking to screen slot can be avoided, light impurity can rise to top as early as possible and discharge, for AOCC raw materials light, that heavy seeds person is more, it is particularly suitable for；Two sections of outer-flowing type pressurized screens with same principle it is right-section tail end slag screened again, accepted stock is combined into stock tank with-section sieve, and two sections of tail end slags are reclaimed again by the frame plansifter that shakes, and good slurry returns to fine-screening system, and screening reject is discharged.
Slurry after fine screen removes the heavy seeds such as tiny sand grains by low dense desander is pumped into, and desander is by three sections of conventional settings of one-level；The concentration of about the 0.8% of desanding disposed slurry improves slurry concentration to 4.5% into many garden disk thickeners, after tieing up shape fiberizer by technique beating, stores into machine chest, and with 3% concentration, by being pumped to paper machine room.
After the slurry of the raw material sent by waste paper pulp-making workshop carries out internal sizing, high-order regulating box is entered with stable flow into slurry, sieve before net with dense being delivered to of 0.6% slurry with the enriched water mixing Jing fan pumps of the outer plain boiled water tower of machine under the control of proportional valve, Jing after sieve screening before net, paper pulp is surfed the Net into head box with the state of low pulse, high turbulent flow.
Before net, the screenings that sifts out enters two sections of pressurized screens, and the good slurry that two sections of pressurized screens are filtered out is sent back to rush and starches plain boiled water bucket, and screenings is drained.
Paper pulp sprays to fourdrinier wire wire side from head box Jing labial laminas, and after web forming dehydration, page enters press section with about 20% mass dryness fraction；In press section after suction couch roll, the big roller blind press squeezing in two roads, l Water Paper page is dried into drying section with about 42% mass dryness fraction, and then, page is batched with the horizontal reel machine of 92% mass dryness fraction Jing；Last rewinding, weigh, winding, end socket warehouse-in.
