Description
Technical field
The present invention relates to a kind of papermaking equipment, relate in particular to and a kind of paper pulp is carried out multistage screening plant.
Background technology
In paper technology, need screen paper pulp, the good slurry that meets the papermaking requirement at first screens, and also needs the fiber in the tailings is also screened, and then screening reject (lumps, sicker, chip etc.) is discharged.The method that prior art is carried out above-mentioned technology is to use the pulp sifting equipment of different size step by step, and its shortcoming is: operating cost height, production efficiency are low, and take a large amount of factory floor space.
Summary of the invention
Technical problem to be solved by this invention provides a kind of multistage sieve for paper pulp that can filter out at least two kinds of paper pulp and screening reject.
For achieving the above object, technical scheme of the present invention is: multistage sieve for paper pulp comprises housing, drive the rotor armature spindle that rotates along the axis setting of housing and by power set, be interval with at least two rotor rotors on the described rotor armature spindle, the medial surface of housing is provided with the screen cylinder of at least two annulars corresponding to the position of rotor rotor, the liquid collecting cavity in the screen cylinder outside is provided with the grout outlet of the paper pulp after the outside output screening, housing between the screen cylinder of described annular is provided with the water inlet that is used for diluted pulp, described water inlet and screen cylinder intracavity inter-connection, one end of described housing is provided with the magma stock inlet, and the other end of described housing is provided with the tail slurry outlet.
The grout outlet of described back level screen cylinder is connected to the screening stock inlet that is arranged on before the prime screen cylinder by defeated slurry passage.
At least two rotor rotors that are interval with on the described rotor armature spindle are the step setting, and the diameter of rotor rotor diminishes successively according to the order of screening, and the intracavity diameter of the screen cylinder corresponding with the rotor rotor also diminishes successively.
Be fixed with the block plate that makes dilution water and paper pulp fully mixed on the described rotor armature spindle between the adjacent rotor rotor.
The described rotor rotor that is arranged on the rotor armature spindle is three.
The grout outlet of described third level screen cylinder is connected to the screening stock inlet that is arranged on before the screen cylinder of the second level by defeated slurry passage.
Owing to adopt technique scheme, multistage sieve for paper pulp comprises housing, drive the rotor armature spindle that rotates along the axis setting of housing and by power set, be interval with at least two rotor rotors on the described rotor armature spindle, the medial surface of housing is provided with the screen cylinder of at least two annulars corresponding to the position of rotor rotor, the liquid collecting cavity in the screen cylinder outside is provided with the grout outlet of the paper pulp after the outside output screening, housing between the screen cylinder of described annular is provided with the water inlet that is used for diluted pulp, described water inlet and screen cylinder intracavity inter-connection, one end of described housing is provided with the magma stock inlet, and the other end of described housing is provided with the tail slurry outlet; A plurality of rotor rotors are installed on the same axle, and the medial surface of housing is provided with the screen cylinder of annular corresponding to the position of rotor rotor, need only like this and can drive complete machine work with a motor, and compact conformation, volume are less, and cost of use is lower.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of the invention.
The specific embodiment
As shown in drawings, multistage sieve for paper pulp comprises housing 1, drive the rotor armature spindle 2 that rotates along the axis setting of housing 1 and by power set, be interval with three rotor rotors 3 on the described rotor armature spindle 2, be fixed with block plate 7 between the adjacent rotor rotor 3 on the described rotor armature spindle 2, the effect of block plate 7 is to make dilution water and paper pulp fully mixed, improves the efficient of screening; The medial surface of housing 1 is provided with the screen cylinder 4 of annular corresponding to the position of rotor rotor 3, the liquid collecting cavity of screen cylinder 4 is provided with the grout outlet 5 of the paper pulp after the outside output screening, housing between the screen cylinder 4 of described annular is provided with the water inlet 9 that is used for diluted pulp, the effect of water inlet 9 is to be used for diluted concentration constantly to become big paper pulp, guarantee that follow-up screen cylinder screens normally, can not stop up sieve aperture because pulp density is too high; The bottom of described housing 1 is provided with magma stock inlet 6, and the top of described housing 1 is provided with tail slurry outlet 8, and the bottom of housing 1 also is provided with the slag-drip opening 12 of discharging the heavier foreign material of quality, and the top of housing 1 is provided with gas outlet 11.
The grout outlet of each screen cylinder can be respectively be transported to next procedure with the paper pulp of each self-sizing, wherein the grout outlet of first screen cylinder comes out be can papermaking good slurry, what the grout outlet of the second and the 3rd screen cylinder filtered out is the paper pulp that can recycle, also can be as shown in drawings, the grout outlet 5 of described third level screen cylinder 4 is connected to the screening stock inlet 10 that is arranged on before the screen cylinder of the second level by defeated slurry passage 19, the paper pulp that third level screen cylinder 4 is sifted out turns back to second screen cylinder and screens once more, so circulation, the pulp sifting of recyclable utilization can be come out, and the grout outlet that passes through second screen cylinder is exported, or directly utilize and make the lower paper of class, also can return fiberizer defibrination again.
Three rotor rotors 3 that are interval with on the described rotor armature spindle 2 are the step setting, and the diameter of rotor rotor 3 diminishes successively according to the order of screening, and the inside diameter of the screen cylinder 4 corresponding with rotor rotor 3 also diminishes successively; Because the proportion of good slurry is bigger in the magma, so the diameter of first screen cylinder is bigger, screen area is just big, so can improve screening effeciency, reduces volume, energy savings.
