Disclosure of Invention
The utility model provides a papermaking waste recycling is used for processing system of spool paper sandwich layer to papermaking waste is the raw materials, reforms transform through the system, can use it for spool paper preparation.
The technical scheme adopted by the utility model is that the papermaking waste recycling system for the bobbin paper core layer comprises a first waste collecting tank and a second waste collecting tank, wherein a feed inlet of the first waste collecting tank is connected with a papermaking slurry pipeline, and a feed inlet of the second waste collecting tank is connected with a sediment pipeline in a water treatment workshop; the discharge gate in first waste material collecting tank and second waste material collecting tank adopts pump and pipe connection to sediment thick liquid mixing tank respectively, and sediment thick liquid mixing tank discharge gate is connected to the pulper, and the pulper discharge gate is connected to the desander, and the desander discharge gate is connected to the shale shaker, and the shale shaker discharge gate is connected to the fiberizer, and the good thick liquid outlet of fiberizer connects concentrated machine of polydisc, and concentrated machine discharge gate of polydisc is connected to sandwich layer thick liquids groove.
Furthermore, a rotating shaft is arranged in the slag and slurry mixing tank, a stirring paddle is mounted on the rotating shaft, and a flow guide hole is formed in the stirring paddle.
Further, the pulper is a hydropulper.
Further, the vibrating screen is a high-frequency vibrating screen.
Further, the vibrating screen is also provided with a slag outlet, and the slag outlet is connected to the pulper.
The waste materials of the paper mill mainly comprise the residue pulp discharged during fine filtration in a paper production workshop and the sediments in a water treatment workshop, the fiber content in the residue pulp and the absolutely dry matters of the sediments is high, if the waste materials are directly treated as wastes, waste is caused, and the environmental protection pressure is increased. The bobbin base paper comprises a surface layer and a bottom layer on the outer side, and a core layer in the middle. The utility model discloses a system that provides utilizes sediment thick liquid and precipitate as the raw materials of middle sandwich layer, changes the technology of using the good thick liquid as the sandwich layer raw materials in the traditional handicraft, can reduce papermaking cost to accomplish the wastes material and recycle, avoid fibrous waste.
If the waste materials of the paper mill are directly used as core layer slurry to produce bobbin paper without treatment, the quality of the bobbin paper can be directly influenced due to the high impurity content of the waste materials, including silt, printing ink sludge, plastic slag and the like, and the produced bobbin paper has low grade and low added value. Adopt the utility model discloses a system handles, can promote the fibre content in the thick liquids, and then promotes the quality of spool paper. The utility model discloses in the system, the sediment thick liquid that the papermaking workshop came is mainly collected to first waste collecting tank, and the deposit that the water treatment workshop came is mainly collected to second waste collecting tank, and material between them adds according to certain proportion in sediment thick liquid mixing tank and mixes, then carries out the pulping, degritting, shale shaker and filters edulcoration and thick liquid and concentrated processing, obtains the sandwich layer thick liquids that fibre content is high, can improve the quality of spool paper.
