Further, the water conservancy diversion groove body is in the distribution setting of dual rotary shape.
Further, the height of described slurry inlet one end is higher than the height of impurity sieve outlet one end.
The use process of the utility model:
Out of, slurry inlet is input to circular drum body internal layer roll screen barrel, which is rolled pulp by internal layer The screening of screen drum enters in the roll screen barrel of middle layer, then passes through the screening of middle layer roll screen barrel, enters in outer layer roll screen barrel, finally By the screening of outer layer roll screen barrel, progress centralized collection processing in slurry collection slot is entered, obtains sieving deimpurity paper pulp slurry Material, due to the water conservancy diversion groove body by setting rotation spiral, not only can make slurries more preferably be flowed into water conservancy diversion in internal layer roll screen barrel It is screened in groove body, and plastic contaminant will not influence the screening of slurry because blocking the sieve screen apertures of internal layer roll screen barrel.
As can be seen from the above description, compared to the prior art, utility model has the advantages that
1, the utility model more fully can be separated and be filtered out and is in slurry miscellaneous by the roller screen cylinder of setting multilayer Matter obtains more preferably pure pulp, changes the device structure for carrying out pulp screening in industry by single layer screen drum.
2, the utility model can not only reduce the circulation speed of slurry by the internal layer roll screen barrel of setting circular cone platform body structure Degree increases the sieving time of slurry, and by the way that water conservancy diversion groove body is arranged in internal layer roll screen barrel, so that slurry is preferably divided From, and the separation that plastic contaminant can be screened preferably without influencing slurries.
3, the utility model structure novel is unique, is more suitable for the use of paper pulp separation screening, changes and use mine in industry The usage mode of material screen cylinder device improves the screening effect of slurry, improves production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the side structure diagram of the utility model circular drum body.
Specific embodiment
Explanation is with reference to the accompanying drawings to further explain specific embodiment of the present utility model.
As depicted in figs. 1 and 2, a kind of screening plant of screening paper pulp slurry, including frame body 1 is screened, on the screening frame body 1 2, two rotating cylinder bodies 3 of circular drum body and a driving motor 4 that one is obliquely installed are installed with, the driving motor 4 is logical It crosses gear and is connect respectively with described two 3 gear drives of rotating cylinder body with rotation axis, two rotating cylinder bodies 3 are fixed to be connected It connects at the both ends of the circular drum body 2, and drives the rotation of circular drum body 2 setting, which includes internal layer Roll screen barrel 21, middle layer roll screen barrel 22 and outer layer roll screen barrel 23, the internal layer roll screen barrel 21, middle layer roll screen barrel 22 and outer layer roller screen Cylinder 23 is arranged for concentric structure, and the internal layer roll screen barrel 21 is in circular cone platform body structure, and on the inner sidewall of internal layer roll screen barrel 21 Offer the water conservancy diversion groove body 211 of rotation spiral distribution;The screening frame body 1 of the exterior bottom of the outer layer roll screen barrel 23 is equipped with a slurry Expect collecting tank 5, the slurry collection slot 5 is for collecting the pulp filtered out, the left and right both ends point of the circular drum body 2 It She You not slurry inlet 24 and impurity sieve outlet 25.
