Embodiment
About detailed description of the present utility model and technology contents, coordinate brief description of the drawings as follows, but appended accompanying drawing is only
There is provided and used with reference to explanation, be not used to limit the utility model.
The utility model provides a kind of fiber recovery of paper mill sludge and recycles equipment, is mainly reclaiming the remaining dirt of papermaking
Fiber mixing slurry in mud is (i.e.：Sludge after processing), and the fiber mixing slurry reclaimed is backfilled and is used for papermaking once again.
In design, recycling must be in the number such as the ring pressure test for not influenceing to do paper product and the chemical oxygen consumption (COC) of drainage
On the premise of, the fiber mixing slurry of proper proportion is added in the raw material stock tank of papermaking, to substitute the wastepaper as raw material of part.
As shown in figure 1, the utility model fiber recovery recycles equipment to include：One sludge treatment pond 1, a papermaking unit 2
And a driver 3, preferably also include a sterilizing unit 4, an odor removal 5, a delivery pipe 6 and one and retain auxiliary agent supply dress
Put 7.
The sludge remaining to house and handle previous papermaking of sludge treatment pond 1.In other words, each papermaking is remaining
Sludge can be all focused in sludge treatment pond 1, so that circulation carries out recycling.
Papermaking unit 2 can only include a single stationery production line, and multiple stationery production lines can be also included simultaneously, and this practicality is new
Type is not limiting as, and section then is described as follows exemplified by including two stationery production lines simultaneously in the present embodiment.
One of them stationery production line includes multiple first raw material stock tanks 21,22, for example, two the first raw material slurries
Groove 21,22 can be respectively a sandwich layer mixing stock tank and a bottom mixing stock tank, to make the first stationery (for example：Corrugated paper)；

Pass through between sludge treatment pond 1 and papermaking unit 2, to be sterilized respectively to fiber mixing slurry, deodorization and reduce fiber loss
(raising fiber retention).
Thereby, the remaining sludge of each papermaking can be all collected into sludge treatment pond 1, by the driving of driver 3, with
The sludge allowed after handling is (i.e.：Fiber mixing slurry) all raw material stock tanks (21,22,26) are backfilling into, that is, papermaking is remaining
Sludge give recycling in papermaking, be used to handling the expense of sludge so as to reach and reduce, and can also be because of there is part
Raw material comes from the backfill of sludge and reduces the cost of paper making raw material.
Certainly, can also be before backfill, first with sterilizing unit 4, odor removal 5 and reservation auxiliary agent feeding mechanism 7, difference
Fiber mixing slurry is sterilized, deodorization and improve fiber retention.
In addition, the utility model fiber recovery recycles equipment also to further comprise：One hand-operated valve V1, multiple regulating valves
V2 and multiple flowmeter FM.Wherein, hand-operated valve V1 is connected between sludge treatment pond 1 and driver 3, to control sludge manually
Whether from the output fiber mixing slurry of sludge treatment pond 1；Multiple regulating valve V2 be connected to driver 3 and each raw material stock tank (21,22,
26) between, to adjust the amount for the fiber mixing slurry for inputting each raw material stock tank (21,22,26)；Multiple flowmeter FM are then connected to drive
Move between device 3 and each regulating valve V2, to detect and/or control the flow of fiber mixing slurry.
In summary, the utility model has following effect compared to present technology：By the recovery remaining sludge of papermaking
In fiber mixing slurry (i.e.：Sludge after processing), and fiber mixing slurry is backfilled into the wastepaper as raw material of replacement part and used once again
In papermaking, so as to reach：First, the expense for handling sludge is reduced；And, two, because there is part material to come from sludge
Backfill and reduce the cost of paper making raw material.
In addition, the utility model also has other effects：By sterilization and the deodorization in advance before backfill, to ensure paper
The spatter property and odorless of finished product.Retain auxiliary agent by being provided in advance before backfill, protected with the fiber for improving fiber mixing slurry
Stay rate.
