Abstract
The utility model relates to a novel rotor of an up-flow coarse mesh. The rotor comprises a fixed seat, a circular rib plate, an outer barrel and a spiral wing which are sequentially connected with one another, wherein the spiral wing is obliquely arranged on the outer barrel; the cross section of the spiral wing has a streamline type structure; and a pulp flow hole is formed in the outer barrel. The rotor has the advantages that: the problems of high power consumption and densification phenomena during screening in the conventional rotor at present are solved, power consumption can be reduced by more than 40 percent, and an energy-saving effect is obvious.
Description
Technical field
The utility model relates to a kind of up-flow scalping novel rotor.
Background technology
Coarse sizing to wastepaper as raw material in the wastepaper pulping and papermaking flow process adopts the up-flow pressurized screen usually, remove plastic sheet in the wastepaper as raw material, plastic foam, the scraps of paper and part heavy seeds that size degradation is not good by coarse sizing, this up-flow screen cylinder 4 has interference stripe simultaneously, interact with rotor 3, the scraps of paper are also had certain effect of discongesting.Its course of work is that waste paper pulp enters pressurized screen inside by stock inlet 11 from the up-flow bottom with certain pressure, under differential pressure action, good slurry flows out from grout outlet 12 by screen cylinder 4, heavy seeds compiles the back in lower housing portion is discharged by heavy cinder notch 13, and light impurity is discharged by top tailings mouth 14, along with the rotation of rotor, screen cylinder 4 constantly obtains cleaning, avoid screen cylinder 4 to stop up, under the effect of rotor 3 and screen cylinder 4 interference stripes, the part slurry is further discongested.This up-flow sieve is partly formed (see figure 1) by housing 1, base 2, rotor 3, screen cylinder 4, transmission device 5 and power set 6 etc.
Existing up-flow sieve scalping screen cylinder mostly is hole sizer, and the sieve plate hole is a taper hole, and several interference stripes are arranged in the screen cylinder; Rotor is a full-sealed rotor, constitutes by holder 1, circular gusset 2, urceolus 3, rotor 4, (seeing Fig. 2 and Fig. 3), and these rotor 3 rotor thickness are big, the vertical bar shape, and running resistance is big, and there is the enrichment phenomenon in the power consumption height.
The utility model content
Technical problem to be solved in the utility model provides a kind of up-flow scalping novel rotor.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of up-flow scalping novel rotor, it comprises holder, circular gusset, urceolus and the rotor that connects successively, described rotor is obliquely installed on urceolus, and the cross section of rotor is a streamlined structure, and described urceolus is provided with stream slurry hole.
Further, described rotor has multilayer, is crisscross arranged on urceolus.
Further, a plurality of streams slurries hole that evenly distributes on the described urceolus, and flow to the top from the bottom of urceolus and to starch the hole and diminish successively.
Further, the thickness of described rotor is 15.9mm～16.1mm.
Further, described urceolus is rolled by corrosion resistant plate and forms.
The beneficial effects of the utility model are: the existing rotor dynamic consumption of up-flow scalping novel rotor of the present utility model obviously reduces.This rotor rotor is a multilayer inclination interlaced arrangement, the rotor thin thickness, only be half of former rotor thickness, running resistance obviously reduces, under the inclination component effect of rotor, the slurry fltting speed is fast, avoided the generation of enrichment phenomenon, the rotor urceolus has a plurality of stream slurries hole simultaneously, in time replenishes unscreened slurry, screen cylinder throughput up and down reaches unanimity, and screening effeciency obviously improves.The utility model has solved the problem that power consumption is big, the enrichment phenomenon appears in screening that at present existing rotor exists, and power consumption can reduce more than 40%, and energy-saving effect is obvious.

The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
As shown in Figure 4 and Figure 5, the utility model up-flow scalping novel rotor comprises holder 1, circular gusset 2, urceolus 3, rotor 4 four parts, holder 1 and circular gusset 2 welding, circular gusset 2 and urceolus 3 welding, urceolus 3 and rotor 4 welding.Rotor 4 is a multilayer inclination interlaced arrangement, and lower floor's rotor 4 is along lagging behind and upper strata rotor 4 certain angles on the direction of rotation, and rotor 4 thickness have only 15.9 millimeters～16.1 millimeters, and rotor 4 cross sections are streamlined; Rotor urceolus 3 forms for corrosion resistant plate rolls, and is distributed with a plurality of stream slurries hole 5 on the urceolus.
The operation principle that the utility model is used for the up-flow sieve is as follows: waste paper pulp enters pressurized screen inside by stock inlet from the up-flow bottom with certain pressure, under differential pressure action, good slurry flows out from grout outlet by screen cylinder, heavy seeds compiles the back in lower housing portion and is discharged by heavy cinder notch, light impurity is discharged by top tailings mouth, along with the rotation of rotor, screen cylinder constantly obtains cleaning, and avoids screen cylinder to stop up.Because this utility model rotor rotor 4 is a multilayer inclination interlaced arrangement, rotor 4 thickness are half of thickness of prior art rotor, running resistance obviously reduces, under the inclination component effect of rotor 4, the slurry fltting speed is fast, has avoided the generation of enrichment phenomenon, the rotor urceolus has a plurality of stream slurries hole simultaneously, in time replenish unscreened slurry, screen cylinder throughput up and down reaches unanimity, and screening effeciency obviously improves.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
