The waste product C that can not pass through the hole of screen frame 9 passes through above-mentioned gap 59.Waste product C by this gap 59 has entered recess 41c, 51c, the 52c that is formed on inclined plane 41b, 51b, the 52b, is subject to the fluid shearing effect because stirring turbulent flow, and the raw material H of contained not macerate is further decomposed by fiber in the waste product C.Be inhaled into the waste product C of waste product chamber 7 and entered the circulating path 28 of rotor 10 by recess 41c, 51c, 52c by the raw material H of macerate from waste product chamber 7, again return sieve inlet 6 by peristome 22b, or be discharged to the outside of screen device 20 from the waste product outlet 3 that is communicated with waste product chamber 7.Decompose by at this recess 41c, 51c, 52c the raw material H of macerate not being carried out fiber, can reduce the amount of waste product C, and reduce the possibilities that waste product is detained in waste product outlet 3.
Below, the effect about the screen device 20 of embodiments of the present invention describes based on Fig. 1.
The paper making raw material A that supplies with from paper making raw material entrance 2 at first enters chamber, feed(raw material)inlet 5, and by throttle orifice 24, has no the ground of omission and be transported to sieve inlet 6 from all-round flowing.And paper making raw material A is positioned at horizontal screen frame 9 extruding of blade 10a by the rotation of rotor 10.At this moment, paper making raw material A be separated into a plurality of holes that can be by screen frame 9 certified products B and can not be by remaining in the waste product C of screen frame 9.
Certified products B enters certified products chamber 8 by screen frame 9, again by throttle orifice 27, from certified products outlet 4 conveying of being flowed to the outside of screen device 20.On the other hand, waste product C is extruded and flow into the little top, gap between the 22a of wall section of screen frame 9 and rotor 10.
The waste product C that flows into the top enters recess 41c, 51c, the 52c that is formed in the macerate section 25, and the raw material H of the not macerate among the waste product C is decomposed by fiber again, and by the mobile waste product chamber 7 that is transported to.The raw material H that is imported into the waste product C in the waste product chamber 7 and is decomposed by fiber is divided into two following liquid streams.
The first liquid stream is inhaled into the circulating path 28 of rotor 10 by the rotation of rotor 10, and by peristome 22b, again flows into sieve inlet 6.And by above-mentioned liquid stream, waste product C is separated into certified products B and waste product C again in sieve inlet 6, and waste product C is again by macerate section 25, and inflow waste product chamber 7.
At this moment, supply with dilution water D from dilution water supply port 11, the concentration dilution of raw material H and waste product C becomes the degree that screen frame 9 can sorting, is trapped in peristome 22b etc. to prevent liquid stream.Especially, the supply port of the lower end of dilution water supply port 11 is positioned at rotor 10 residing central portions and is positioned at the inboard of the peristome 25c of macerate section 25, thereby dilution water D flows directly into the circulating path 28 of rotor 10, can more effectively assist the first liquid stream.
In above-mentioned macerate operation, with the degree of the size of the kind of macerate raw material not or raw material or macerate correspondingly, at random the dismounting macerate is with the fiber decomposition unit 52 of rotor 25b side.That is, macerate is insufficient, is attached with among the waste product C in the situation of a large amount of certified products B, uses recess 41c, 51c, the 52c of 3 level structures.Thus, can promote the macerate of the certified products B among the waste product C.
On the other hand, certified products B adheres in few situation, pulls down and appends with fiber decomposition unit 52, uses 2 grades recess 41c, 51c.Thus, waste product C is not trapped in macerate section 25, can finish as soon as possible the macerate operation.
By these operations, the not macerate sheet (certified products B) among the waste product C is decomposed by fiber effectively.
In addition, have the baffle plate 21a of covering sieve inlet 6, waste product chamber 7 and macerate section 25 and the cover 21b that can open and close, macerate consists of in the face of the opening ground of having opened this cover 21b with rotor 25b with stator 25a and macerate, thereby can be from this opening dismounting macerate stator 25a and macerate rotor 25b.Thus, can carry out easily macerate is used rotor 25b with stator 25a and macerate replacing.
And, macerate with stator 25a and macerate with the bolt 62,63,72 of rotor 25b by disassembled and assembled freely, 73 fastened, because this bolt 62,63,72,73 can consist of removably from the opening of cover 21b, so can easily carry out macerate is used rotor 25b with stator 25a and macerate dismounting operation.
In addition, macerate adopts with rotor 25b cuts apart structure, and this part of cutting apart by dismounting can change the progression of the ladder that is made of recess 41c, 51c, 52c, thereby can be with size or the macerate situation of macerate raw material are not correspondingly suitably set ladder.Thus, fiber decomposes not macerate sheet effectively.
In addition, since be provided with for install by bolt 62,72 the fiber decomposition unit 61 of macerates with stator 25a, 81 and macerate with the fiber decomposition unit 71 of rotor 25b, each base portion 60,70 of 91, so can make fiber decomposition unit 61,81 and the shape of fiber decomposition unit 71,91 mounting portion identical.Thus, can suitably change these fiber decomposition units 61,71,81,91.
More than, be illustrated about the screen device of embodiments of the present invention, but the invention is not restricted to above-mentioned embodiment, can carry out various distortion and change based on technological thought of the present invention.
For example, in the present embodiment, disassembled and assembled freely ground consists of fiber decomposition unit 41 and appends with fiber decomposition unit 51, and the progression of recess can freely change over 2 grades and 3 grades, but the progression of this ladder is not limited to this.That is, by use progression be macerate more than 3 grades with stator and macerate rotor, can also further promote the not macerate of macerate raw material.In this situation, can append with the progression of the recess of fiber decomposition unit by increase and realize, perhaps, can also realize by the progression that increase is appended quantity with the fiber decomposition unit and increased recess.
In addition, in the present embodiment, macerate adopt fiber decomposition unit 51 with the fiber decomposition unit of rotor 25b and append with fiber decomposition unit 52 such cut apart structure, cut apart structure but macerate is become with the fiber decomposition unit of stator 25a, and can consist of removably the part of cutting apart.In this situation, by macerate is changed over splayed with rotor 25b and macerate with the inclination of stator 25a, can carry out dismounting to the part of cutting apart.Thus, can change the progression of the ladder that is formed with the recess of stator 25a by macerate.
In addition, in the present embodiment, append the progression that changes recess with fiber decomposition unit 52 by dismounting, append with fiber decomposition unit 52 but also can not arrange, by dismounting, change fiber decomposition unit 41,51 and self change recess 26(with reference to Fig. 3 and Fig. 4) progression.
Fig. 3 is the figure of the expression variation corresponding with the II part of Fig. 1, and the progression of relative recess constitutes 2 grades.
Macerate is made of base portion 60 and the fiber decomposition unit 61 that is positioned at the upside of this base portion 60 with rotor 25b.
In addition, fiber decomposition unit 61 is installed in the upper surface of this base portion 60 by bolt 63.This bolt 63 is the bolts with hexagonal hole.And, be formed with counter sink at the upper surface of fiber decomposition unit 61, under the state of bolt 63, the head of bolt 63 is outstanding from the upper surface of fiber decomposition unit 61 fastening.
These bolts 62,63 respectively under the state of having opened cover 25b the upside from this opening be inserted into.That is, under the state of having opened this cover 21b, macerate consists of in the face of this opening ground with stator 25a.In addition, can be from this opening assembling-disassembling bolt 62,63.And, can from open the opening of this cover 21b, come dismounting, change fiber decomposition unit 61 by assembling-disassembling bolt 62.Thus, can change macerate stator 25a(base portion 60 and fiber decomposition unit 61).
Macerate is made of base portion 70 and the fiber decomposition unit 71 that is positioned at the upside of this base portion 70 with stator 25a.
In addition, fiber decomposition unit 71 is installed in the upper surface of this base portion 70 by bolt 73.This bolt 73 is the bolts with hexagonal hole.And, be formed with counter sink at the upper surface of fiber decomposition unit 71, under the state of bolt 73, the head of bolt 73 is outstanding from the upper surface of fiber decomposition unit 71 fastening.
Thus, can change macerate rotor 25b(base portion 70 and fiber decomposition unit 71).
Fig. 4 be expression from the state of Fig. 3 changed respectively macerate with the fiber decomposition unit 61 of stator 25a, and macerate with the cutaway view of the state of the fiber decomposition unit 71 of rotor 25b.
Macerate shown in Figure 3 with the fiber decomposition unit 61 of stator 25a, and macerate consist of by 2 grades with the progression of the relative recess in the fiber decomposition unit 71 of rotor 25b, but macerate shown in Figure 4 with the fiber decomposition unit 81 of stator 25a, reach macerate and consist of by 3 grades with the relative ladder in the fiber decomposition unit 91 of rotor 25b.
That is, not by in the few situation of the not macerate raw material of macerate, this progression adopts 2 grades and carries out macerate in screen frame 9.On the other hand, in the situation that the macerate raw material is not many, this progression adopts 3 grades, and making not, the macerate raw material contacts to promote macerate with more this step portion.That is, progression is more, and the friction of waste product C and step portion or waste product C friction are each other carried out manyly, thereby promotes the not macerate of macerate raw material.
