The cleaning of splenium.
As the improvement of above-mentioned technical proposal, the paper machine white water processing system also includes distinguishing with the multi-disc filter
The blending chest of connection, pure pond and turbid white water chest, the blending chest are used to collect recovery slurry, and recovery slurry is for paper machine
With slurry, the pure pond is connected with deslagging device, and the deslagging device is used to carry out the pure water in pure pond to slurry
Slagging-off cleaning, the turbid white water chest are used to collect turbid plain boiled water.
Multi-disc filter handles paper machine white water classification, is recycled slurry, pure water and turbid plain boiled water；The slurry of paper machine white water
Concentration is 0.15%~0.3%, and the slurry concentration in recovery slurry is 3%~4%, in pure water slurry concentration be 0.005%~
0.01%, the slurry concentration of turbid plain boiled water is 0.03%~0.05%；Blending chest is used to collect recovery slurry；Pure pond is used to receive
Collect pure water, pure current direction deslagging device, the slurry in device is streamed to paper machine and cleaned；Turbid white water chest is turbid for collecting
Plain boiled water.
Further improved as above-mentioned technical proposal, the pure pond is also associated with flush pipe, and the flush pipe is used
Fall in the pure water in pure pond is carried out into punching to the paper web of pulper.The pure current direction punching in pure pond falls pipe, and punching falls pipe
In pure water be used for pulper paper web punching fall.
Further improved as above-mentioned technical proposal, the turbid white water chest and the paper machine white water groove and the polydisc mistake
Pipeline connection between filter.The turbid plain boiled water circulation of turbid white water chest flows to multi-disc filter, and turbid plain boiled water is repeatedly reclaimed, kept away
Exempt to waste.
As the improvement of above-mentioned technical proposal, the paper machine white water processing system also includes bed course stock tank, the bed course slurry
Pipeline connection between groove and the paper machine white water groove and the multi-disc filter, the bed course stock tank provide for multi-disc filter
Bed course is starched.Slurry concentration is 3%~4% in bed course slurry, and bed course is starched and mixed with paper machine white water, then flows to polydisc filtering
Machine；On the one hand the waste that bed course can be avoided to starch, it on the other hand can increase fibre concentration in recovery slurry, be easy to recovery with slurry.
The beneficial effects of the utility model are：Paper machine white water processing system of the present utility model is provided with multi-disc filter,
Multi-disc filter handles paper machine white water classification, can be recycled slurry, super pure water, pure water and turbid plain boiled water, recovery slurry can
With direct reuse to stock mixing system, and the clear water containing different slurry concentrations can be used for removing the gred, clean.
Brief description of the drawings
Fig. 1 is a kind of paper machine white water processing system；
Wherein, 1, paper machine white water groove, 2, multi-disc filter, 3, super pure pond, 4, spray tank, 5, blending chest, 6,
Pure pond, 61, deslagging device, 62, flush pipe, 7, turbid white water chest, 8, bed course stock tank.
Embodiment
For the purpose of this utility model, technical scheme and advantage is better described, below in conjunction with specific embodiment and attached
The utility model is described in further detail for figure.
A kind of paper machine white water processing system include be sequentially connected by pipeline paper machine white water groove 1, multi-disc filter 2, surpass
Pure pond 3 and spray tank 4, spray the spray that the super pure water in tank 4 is used for paper machine net splenium.
The paper machine white water processing system also includes blending chest 5, the pure pond 6 being connected respectively with multi-disc filter 2
With turbid white water chest 7, for the recovery slurry of the blending chest 5 for the with slurry of paper machine, pure pond 6 is connected with deslagging device 61, removes
