Description

For manufacture the equipment of fibre pulp from lignocellulose-containing material
Technical field
The present invention relates to a kind of fine according to manufacturing from lignocellulose-containing material of claim 1 preambleThe equipment of dimension paper pulp.
Background technology
A kind of disc type paste mill or grinder comprise housing, and this housing surrounds two relative defibrination dishes, whereinHave at least one to be rotary type. Defibrination dish has element for refining separately, between them, is formed with between defibrinationGap, for by lignocellulose-containing material (for example from cork or hardwood, bamboo, straw, bagasse orThe fragment of analog) disintegrate into fibre pulp. The space of paper pulp by the rear side of rotary defibrination dish fromDrive fiberizer. A problem is that paper pulp adheres to described rear side and the shell of rotary defibrination dish, and rightBearing produces power, and this power may be destroyed bearing. Burning may pine after the accumulating in of fibre bundle or particleMove and next in other procedure of processing, have problems. Common problem is for example point on plate.
Be known that and there is the straight wing element of aiming at along empty RADIAL on the rear side of rotary defibrination dish, in caseOnly paper pulp adheres to rear side and/or shell. Their problem is enough ineffective. In addition, they have turbulizationTendency, this can produce wearing and tearing.
Summary of the invention
The object of the invention is to solve problem by the invention of claim 1.
Place wing member by becoming positive angle from empty RADIAL towards direction of rotation, realize rotary defibrination dish afterSide is clean and wearing and tearing still less better. In addition, because the throughput direction of particle will be more directly towards defibrinationThe periphery of dish, is preferably positioned with outlet at this place, so can save energy.
Other advantage can realize by the different embodiment in dependent claims.

Fig. 3 is the schematic elevational view that equipment in the Fig. 1 of another exemplary embodiment according to the present invention is shown.
Fig. 4 a-e illustrates schematically looking of equipment in the Fig. 1 of the another exemplary embodiment according to the present inventionFigure.
Detailed description of the invention
In Fig. 1 and 2, disclose according to fiberizer 1 of the present invention, this fiberizer is for from containing wood fibreCellulosic material is manufactured the example of the equipment 1 of fibre pulp. Fiberizer 1 comprises shell 2, and shell 2 surrounds fixingFormula defibrination dish 3 and rotary defibrination dish 4, fixed defibrination dish 3 is also referred to as stator, rotary defibrination dish 4Also referred to as rotor. Fixed defibrination dish 3 can be connected to shell 2. Rotary defibrination dish 4 passes through rotating shaft5 are driven and are preferably rotated with 1500-2300rpm by motor (scheming not shown). Also can there are twoRotary defibrination dish 3,4. Defibrination dish 3,4 is provided with element for refining 6,7 at it on surface each other,Between element for refining 6 and 7 self, be limited with grinding clearance 8, this grinding clearance 8 is preferably 0.1-2mm。
Fixed defibrination dish 3 has entrance 9, treats that the material of defibrination enters gap 8 by this entrance feeding. ?Material preferably preheats this material with for example steam before being entered fiberizer 1 by feeding, and at defibrinationIn machine 1 under pressure defibrination. Before material is entered fiberizer 1 by feeding, can also carry out chemistry to this materialProcess.
In gap 8, first this material is preferably fractured into thin rod, and these thin rods are outside by centrifugal forceFeeding, to milling zone, is opened and processes at this place's fiber, and the surface that causes them to become softness and fiber is obtainedObtain binding ability well.
Between shell 2 and the rear side 11 of rotary defibrination dish 4, be provided with space 10. In fiberizer 1, locateThe material of reason is collected in space 10 and by exporting 18 and leaves fiberizer 1.
The rear side 11 of rotary defibrination dish 4 is provided with center 14 and periphery 17. At least one empty RADIAL 13At least extend to periphery 17 from center 14.
In order to prevent that the material after processing from sticking to rear side 11 and the shell 2 of rotary defibrination dish 4, rear side 11Also be provided with at least one wing member 12. Wing member 12 can be a part for rotary defibrination dish 4, can pass throughFor example in rear side 11, between wing member 12 is by two positions that arrive, forming greater or lesser otch comes realExisting. But wing member 12 is preferably separated with rotary defibrination dish 4 but is attached to rotary defibrination dish 4, because ofFor time can easily changing wing member 12 in wearing and tearing like this, and wing member can also by with rotary defibrination dish 4Different materials are made, and are preferably harder material and make. Harder material is more expensive and because the wing conventionallyPart 12 is wear-out parts, and the area of wing member 12 is preferably less than the area between wing member 12. In addition, ifWing member 12 is separated with rotary defibrination dish 4 instead of in rotary defibrination dish 12, is made otch, defibrinationThe manufacture of machine 1 is simplified.
At least one wing member 12 for example, (to be greater than zero positive angle α, α 1, α 2, α 3 with 13 one-tenth of empty RADIALs45 ° of left and right) towards direction of rotation R, instead of by the radially aligned placement of all wing members. DifferentWing member can from the different angled α of empty RADIAL 13, α 1, α 2, α 3. Wing member 12 is preferably to refer toPattern to the direction contrary with direction of rotation R is placed. Limit a pattern as being arranged in rotating shaft 5 with outerOne group of wing member 12 between week 17. Then can repeat symmetrically this pattern around rotating shaft 5. Due to wing member12 with the angled α of empty RADIAL 13, α 1, α 2, α 3, wing member 12 can specific diameter be placed to alignedWing member is worked better, because material more effectively throws away from the center 14 of rotary defibrination dish 4. This bandBetter clean and wearing and tearing are still less carried out. In addition, because the throughput direction of material will be more directly towards rotationThe periphery 17 of formula defibrination dish 4, is preferably positioned with outlet 18, so can save energy at this place.
In Fig. 2, all angle [alpha] identical with 13 one-tenth of empty RADIALs of all wing members 12. But, betterGround is, as shown in Figure 3, further from the wing member 12c at the center 14 of rotary defibrination dish 4 than more closeWing member 12b, the 12a at the center 14 of rotary defibrination dish 4 with less angle [alpha] 3 (in this situation, angleα 3 can be as small as 0 °) arrange, wing member 12b, 12a place with increasing angle [alpha] 2, α 1. This isBecause the closer to center 14, the rotary speed of material is lower, and therefore larger angle is preferred.
As shown in Figures 2 and 3, wing member 12,12a, 12b, 12c little, straight, that separate are warpsJi because their manufacture the most cheap and people only need to change the most severe wing member 12 of wearing and tearing, 12a, 12b,12c, and must not change whole wing members simultaneously. But, if being provided with, wing member 12 is assemblied in rotary defibrinationGuard ring 15 in the respective slot 16 of dish 4 rear side, can obtain stronger attached.
In Fig. 4 a-c schematically illustrated wing member 12 other substitute, wherein wing member 12 is on whole pathMore or less march to the periphery 17 of rotary defibrination dish 4 from rotating shaft 5. Wing member 12 can be straight orBending and there is width identical or that change. As shown in Fig. 4 a and 4b, can have one allPath all marches to the wing member 12 of the periphery 17 of rotary defibrination dish 4 from rotating shaft 5. Or, Ke YiyouMultiple wing members of separating 12 that are disposed to periphery 17 from rotating shaft 5, as shown in Fig. 2,3,4d and 4eGround is spaced apart, or overlapping as shown in Fig. 4 c. For stable, wing member 23 is preferably with respect to rotationAxle 5 is arranged symmetrically with. Respectively illustrate 2-4 pattern, but more many types of formula is also possible.
Certainly, the embodiment shown in the invention is not restricted to, but can in the scope of claims, change.
