Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Embodiment: a kind of paper manufacturing systems for reducing sludge and generating, referring to Fig. 1, the processing of waste paper is needed by following process:
Highly concentrated pulping process 1, floatation and ink removing process 2 and dehydration procedure 3.
Waste paper adds water to be crushed waste paper in highly concentrated pulping process 1 by high-concentration pulper, and waste paper is become paper pulp.Paper
There are a large amount of paper fiber and ink in slurry, a large amount of ink influences whether that following process goes out the quality of paper, therefore needs to oil
Ink is cleared up.Paper enters floatation and ink removing process 2.It needs to be added in paper pulp before by floatation and ink removing process 2 big
The water of amount, is diluted paper pulp.
Paper pulp after dilution passes through multiple flotation in floatation and ink removing process 2, is divided into one section of ink and two sections of ink.One section black
Ink is thicker, it is difficult to using being discharged into sewage plant 5；Quantity of ink in two sections of ink is less and there are certain paper fiber, can be with
It is discharged into stop in pond 4 and be recycled.
Paper pulp is excluded in paper pulp after existing ink, is needed by dehydration procedure 3 to paper after floatation and ink removing process 2
Slurry is dehydrated.Dehydration procedure 3 uses polydisc dewaterer, and the paper pulp after dilution after dilution, enters in polydisc dewaterer
Papermaking process 6 on to paper machine.
The black quantity of ink of two sections floatingly selected in floatation and ink removing process 2 is less and there are certain paper fibers, is drained into stop
It waits and recycling in pond 4.The paper pulp fiber for also remaining part in the water deviate from dehydration procedure 3 discharges it into and stops pond 4
Inside recycled.Also it can deviate from the water containing paper pulp fiber in papermaking process 6, equally discharge it into and stop in pond 4.It stops
There are a certain proportion of fiber in water in pond 4, be directly discharged to sewage plant, by sewage plant processing meeting so that fiber with dirt
The form of mud deposits.
Therefore be diluted the water stopped in pond 4 to paper pulp after highly concentrated pulping process 1, it can be in stop 4 water of pond
Limit recycled, improve the utilization rate of limit, to reduce the fiber that is discharged into sewage plant, reduce in sewage plant
Sludge.And improve the utilization rate of water.
Referring to figs. 2 and 3, flotation ingot stripper includes body 21, the inlet 22 that 21 side of body is arranged in, is arranged in machine

Nylon wire 321 is wound on hexagonal reel 32, the fiber of two Duan Mozhong is difficult to through nylon wire 321, from hexagonal reel 32
The other end enter in paper pulp pond 34, then enter in dehydration procedure 3 and be dehydrated from paper pulp pond 34, the sewage with ink
It enters in cesspool 31, and is entered in sewage plant 5 from cesspool 31.The both ends of hexagonal reel 32 are respectively arranged with motor 322
With belt interlinked mechanism 323, multiple hexagonal reels 32 is driven to be interlocked.
Flowchart process: waste paper is crushed and is diluted in highly concentrated pulping process 1, and the paper pulp after the completion of diluting enters floating
It selecting and carries out floatation and ink removing in deinking process 2, paper pulp is entered in dehydration procedure 3 and is dehydrated later, after the concentration for reaching demand,
It is added to progress papermaking process 6 on paper machine.In dehydration procedure 3, floatation and ink removing process 2 and papermaking process 6, it can generate and contain
There is the waste water of fiber, the waste water containing fiber is passed into stop in pond 4 and be kept in, and for arriving highly concentrated pulping process, reduces
The discharge and waste of fiber, reduce the generation of sludge.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
