In the screen as shown in FIG. 1 in which the sub-disc screen plate 7, the sub-disaggregation blade 9 and the like are present, the papermaking raw material is directly applied to the disc-shaped screen plate 1 and the disaggregation blade 8. Further, the other papermaking raw material enters the annular chamber 5 through the communication passage 6, and is slushed to the sub-disc-shaped screen plate 7 by the sub-disaggregation blade 9 to be sufficiently disintegrated. .

At this time, the undisaggregated raw materials and impurities (hot melt, foreign matter, binding fibers) that do not pass through the disc-shaped screen plate 1 and the sub-disc-shaped screen plate 7 are generated by the rotation of the disaggregation blade 8 and the sub-disaggregation blade 9. The outer periphery of the first processing unit main body A and the like are removed by the centrifugal force and discharged from the reject outlet 4b. Further, the light foreign matter in the raw material is collected at this portion and is discharged to the outside from the discharge port 4a because the upper portion corresponding to the air-core portion of the annular material 5 becomes the center of the low-pressure vortex flow.

The primary disintegrated papermaking raw material then enters the stock room C in the second processing section main body B, and the sorting room 13
Alternatively, the inside sorting chamber 13a and the outside sorting chamber 13b are entered. The papermaking raw material entered here is sorted by the inner cylindrical screen plate 11 and the outer cylindrical screen plate 12 by the rotation of the stirring body F. The selected good raw materials pass through the inner cylindrical screen plate 11 to be selected as the inner stock room D in the second processing unit body B, and pass through the outer cylindrical screen plate 12 to be selected as the outer stock room E, respectively. The good raw material carried to the inner stock room D and the outer stock room E becomes the selected raw material through the raw material outlet 3.

It is divided into an outer stock room E having an outer cylindrical screen plate 12, and the inner cylindrical screen plate 11 and the outer cylindrical screen plate 12 are separated from each other at appropriate intervals by a sorting chamber 13 communicating with the stock room C. , The sorting room
First, the stirring member F that rotates on the drive shaft 10 is provided in the screen 13, and the raw material outlet 3 that communicates with the inner stock room D and the outer stock room E is provided. And the selection is processed by one,
Moreover, the efficiency of disaggregation and selection can be greatly increased,
Secondly, it is possible to increase the throughput, and at the same time, it is possible to reduce the power consumption. Thirdly, it is possible to prevent the raw material from being forced to pass through the screen plate. Fourthly, since the pulsation is small, it has no effect on the paper making and has the effect that the product can be made uniform on the paper making machine.

These effects will be described in detail. First, the first processing section main body A having the raw material inlet 2 and the second processing section main body B having the raw material outlet 3 are formed via the disc-shaped screen plate 1, 2 A disintegrating blade 8 that rotates on a drive shaft 10 pivotally attached to the processing unit main body B is provided in the first processing unit main body A close to the disc-shaped screen plate 1, and the second
An inner stock room D having an inner cylindrical screen plate 11 and an outer stock room E having an outer cylindrical screen plate 12 after the processing unit main body B is sorted by the stirring body F in the sorting chamber 13 are provided. Therefore, in the first processing section main body A, the fed papermaking raw material is first cut by the edge by the disaggregation blade 8 which is brought close to the disc-shaped screen plate 1, and at the same time as the disaggregation blade 8 Thrashing is performed between the disc-shaped screen plate 1 and the disc-shaped screen plate 1 for good disaggregation. This disintegrated papermaking raw material is directly selected in the second processing section body B on the lower side or the like, this time by the stirring of the stirring body F, through the inner cylindrical screen plate 11 and the outer cylindrical screen plate 12. This means that a single machine can perform extremely efficient disaggregation and selection work, which not only saves equipment costs, but also enables disaggregation and selection to be good, providing higher quality papermaking materials. It also has the advantage of becoming

Further, according to the present invention, in particular, the inner tubular screen plate 11 and the outer tubular screen plate 12 are provided in the second processing unit main body B at two locations, and the agitating body F swirls them for selection. Thus, even if the processing amount of the papermaking raw material can be simply doubled or increased, that is, even if the opening area is increased and the processing amount is increased, the torque of the motor 23 is At a substantially constant pressure difference (difference between the inlet pressure and the output pressure) and a substantially constant raw material concentration (about 2% to about 3%), there is almost no change, and therefore the papermaking raw material for the same power consumption amount The processing amount is remarkably increased, and as a result, the power consumption amount per unit processing amount can be reduced.

For this reason, even if the same model is downsized, the same effect can be obtained, and there is an effect of reducing the facility cost.

Further, it is needless to say that the same machine type has the effect of significantly increasing the throughput of papermaking raw materials.

Furthermore, the two selected areas, the inner cylindrical screen plate 11 and the outer cylindrical screen plate 12, double the selected area, reducing the pressure difference (difference between inlet pressure and outlet pressure). Even so, it becomes possible to select carefully. Therefore, the papermaking raw material can be operated with a pressure difference that does not forcefully pass through the inner tubular screen plate 11 and the outer tubular screen plate 12, and this has the advantage that impurities can be greatly removed from the treated raw material. is there. That is, the screening effect can be made extremely large.

At 21 a partition is formed in the inner sorting chamber 13a and the outer sorting chamber 13b,
Since the agitating body F which rotates on the drive shaft 10 is provided in each of the inner sorting chamber 13a and the outer sorting chamber 13b, the inner sorting chamber 13a and the outer sorting chamber 13b can be independently configured. As a result, the papermaking raw material in the inner sorting chamber 13a can flow exclusively in the centripetal direction and can be in the laminar flow state, and at the same time, the papermaking raw material in the outer sorting chamber 13b can also be in the centrifugal direction and can be in the laminar flow state. Therefore, the flow of the papermaking raw material in each of the sorting chambers 13a and 13b becomes extremely smooth, and the selection can be made more suitable.

The other structure is the same as that of the first aspect of the invention and has the same effect.

Next, in the invention described in claim 3, in the first processing section main body A in the invention described in the first aspect, a plurality of communication passages 6, 6, are provided in the first processing section main body A. Is provided with an annular chamber 5 communicating with the second processing unit main body B, and a sub-disc-shaped screen plate 7 corresponding to the disc-shaped screen plate 1 is provided in the annular chamber 5, and the disc-shaped screen plate 1 and Since the defibration blades 8 and the auxiliary defibration blades 9 that rotate on the drive shaft 10 pivotally attached to the second processing unit body B are provided while being close to the respective surfaces of the sub-disc-shaped screen plate 7,

The second processing unit main body B is the one that can be slushed and disaggregated and passed through the disc-shaped screen plate 1 and the sub-disc-shaped screen plate 7.
Out of stock room C and ring room 5, especially ring room 5
The materials are merged with the stock material in the stock room C through the communication passages 6, 6, ... And are sent to the screening process through the stirring in the sorting chamber 13.

In particular, the disk-shaped screen plate 1 and the sub-disk shaped screen plate 7 are provided at two locations, and the dissociation blades 8 and the sub-disaggregation blades 9 are used to disintegrate them, thereby improving the throughput of the papermaking raw material. It can simply be doubled or increased to the same extent, which increases the opening area and the throughput of disaggregation, and the torque of the motor 23 is still substantially constant at a substantially constant pressure difference. Yes, the processing amount of papermaking raw material for the same power consumption amount increases significantly, and as a result, it is possible to reduce the power consumption amount per unit disaggregation processing amount,
The disaggregation efficiency can be remarkably increased.

In addition, this disaggregation action and the fine selection action detailed in the first aspect of the invention act synergistically to increase the throughput, and make the disaggregation and fine selection more accurate, and achieve high-quality papermaking raw material processing. There is an effect that can be provided. Further, the other structure is the same as that of the first aspect of the invention and has the same effect as this.
