Description
Technical field
The present invention relates to pulp technology for making paper, and in particular to a kind of paper pulp dispersing apparatus for paper mill.
Background technology
Papermaking is the important invention of ancient china working people.Being divided to has mechanism and by hand two kinds of forms.Mechanism is in papermaking
It is carried out continuously on machine, the paper pulp of paper quality will be suitable for, be diluted with water to finite concentration, is tentatively taken off in the wet end of paper machine
Water, forms wet page, then through press dewatering, be then dried into paper.
It is manual then with the framework for having bamboo curtain splint, polyester webs or copper mesh, the scattered fiber suspended in water is copied into l Water Paper page, warp
Press dewatering, then row dry or are dried into paper.Mechanism and by hand two kinds of paper maximum differences created are, because hand-made paper is adopted
Manually it is beaten, the fiber in paper pulp is intact；Machine-made paper is beaten using machine, and paper pulp fiber is broken so that hand-made paper
Machine-made paper is significantly better than on toughness pulling force.Machine-made paper, which has slurry network speed difference, causes fiber aspect to skewness, and hand-made paper is not
There is fiber aspect uneven to distribution proportion, be especially embodied on painting paper (such as：Rice paper).
When carrying out the preparation of paper pulp, machine is smashed fiber to obtain the paper pulp of exquisiteness, so as to obtain texture more preferably
Paper.In the prior art, the degree of fragmentation of fiber does not reach requirement also, causes papermaking second-rate.
The content of the invention
It is an object of the invention to provide a kind of paper pulp dispersing apparatus for paper mill, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the present invention provides following technical scheme：
Symmetrically two are fixedly connected with a kind of paper pulp dispersing apparatus for paper mill, including housing, housing left and right sidewall
Support column is fixedly connected with individual mounting seat, mounting seat, the top of two support columns is fixedly connected with supporting plate, the branch jointly
Fagging middle, which is fixedly connected with motor, motor output shaft, is fixedly connected with rotating shaft, and rotating shaft is located at enclosure interior；The rotating shaft
Screw auger is fixedly connected with the wall of side, screw auger outer cover is provided with sleeve, and sleeve bottom end is fixedly connected with housing inner bottom part,
The sleeve top is fixedly connected with disk, and disk is internally provided with cavity, and cavity is connected with sleeve inner, in the cavity
Portion, which is fixedly connected with some vertically-mounted posts, vertically-mounted post, has been evenly arranged some impact projections；The disk lower side
The first through hole of some connection cavitys and enclosure interior is offered at edge；Symmetrically it is fixedly connected with rotating shaft above the disk
Two horizon bars, the other end of horizon bar is fixedly connected with vertical bar, and two vertical bar bottoms are fixedly connected with upper millstone jointly,
Some material spilling holes are uniformly offered on upper millstone；Lower millstone, upper millstone downside and lower millstone are provided with below the upper millstone
If it is raised that upper side has been fixedly connected with dry grinding.
It is as further scheme of the invention：Spacing between the screw auger and set medial wall of the tube is 3mm-8mm.
As the present invention, further scheme is：Uniformly offered on the wall of the sleeve bottom side several second lead to
Hole.
As the present invention, further scheme is：The raised impact is in tetrapyamid shape, and grinding is raised in hemispherical.
As the present invention, further scheme is：The upper millstone is not in contact with case inside wall, and lower millstone passes through
Some fix bars are fixedly connected with case inside wall and sleeve lateral wall.
As the present invention, further scheme is：Discharging channel, discharging channel are offered on the wall of the housing bottom side
On be provided with valve.
The beneficial effects of the invention are as follows due to offering on the downside of disk, first through hole number is less, the velocity of discharge of paper pulp is small
In the lifting speed of screw auger, then the paper pulp in cavity can be more and more, so that causing the pressure of cavity inside increases, paper pulp
It can be sprayed at first through hole, and spouting velocity is increasing；At the same time, paper pulp can strike under pressure impacts convex
On rising, the raised fiber in paper pulp of impact carries out cutting and crushing processing, so as to further be refined to fiber；Upper millstone
Processing is further ground to paper pulp with being disposed with grinding projection on lower millstone, paper pulp is further increased spacing
Granularity, improve papermaking quality.The present invention has the advantages that reasonable in design, easy to use and fiber crushing effect is good,
With certain application value.
