Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fibrous substance sorting apparatus.

[0002]

2. Description of the Related Art As shown in FIG. 13, a conventional fiber component sorting apparatus has a sorting container 1 having a fiber portion inlet 2 tangential to the upper cylindrical portion of the container 1 and a tangential direction to the central cylindrical portion of the container. The short fiber fraction aggregate outlet 3 is arranged below the container, and the long fiber fraction aggregate outlet 4 is arranged. A lid 5 is provided on the upper portion of the container 1, and an air outlet 6 is provided at the center of the lid 5. A sorting cylinder 7 having a large number of pores or slits is arranged in the container 1 to sort the fibers, and the sorting cylinder 7 is fixed to the container 1 by a fixed ring 8. 7 forms an isolation wall between the long fiber fraction aggregate and the short fiber fraction aggregate. The stirring device provided in the center of the container 1 is configured as follows. That is, the rotating drum 10 having a plurality of hemispherical protrusions 9 on the surface of the rotating body.
Is fixed to the upper end of a main shaft 11 for transmitting rotation, and the main shaft is supported by two sets of upper and lower bearings, and the bearing device 1
It is fixed at 2. The bearing device 12 is fixed to the container 1 and constitutes a part of the container 1 for holding the pressure in the container 1. The rotating drum 10 can be rotated by a power transmission device 13 such as a belt, and it is intended to prevent sedimentation of fiber in the container, clean the surface of the sorting cylinder 7, and prevent clogging of the sorting cylinder. In such a sorting device, the fiber component supplied from the fiber component inlet 2 is supplied to the sorting cylinder 7 and the rotary drum 1.
In the process of passing through the region of 0, the short fiber component flows through the pores of the sorting cylinder 7 to the short fiber component aggregate outlet 3, and the long fiber components that cannot pass through the pores of the sorting cylinder 7 are It advances downward and is discharged from the long fiber fraction aggregate outlet 4. The opening of the selection cylinder 7 may be a round hole or a slit.

[0003]

In such a sorting apparatus, demands for enhancing the sorting effect of fibrous substances are increasing day by day, and therefore, a sorting cylinder having a small hole or a narrow slit is inevitably adopted. Among them, since it is necessary to increase the number of sorting devices in order to enhance the sorting effect, it is becoming a problem that the installation space is expanded and the power is increased. More specifically, in the conventional sorting device, the ratio between the axial length of the sorting cylinder and the inner diameter of the sorting cylinder is usually 0.9 to 1.2 times, but the throughput of the sorting device is increased. Therefore, when the length ratio (length of the sorting cylinder / diameter of the sorting cylinder) is increased, the concentration of fibers flowing on the side of the long fiber fraction aggregate is significantly increased, that is, the concentration ratio becomes large and There is a problem that the length ratio cannot be increased because clogging easily occurs and operation is stopped. In addition, in the sorting device having the conventional configuration, not only the equipment cost increases as the number of machines increases, but also the machine loss corresponding to the increase in the number of machines increases, so that the power efficiency deteriorates. Further, if the diameter of the sorting cylinder is increased in order to reduce the number of sorting devices to be used, there is a drawback that the power consumption amount per unit processing amount deteriorates. In view of the above, the present invention is intended to solve the above-mentioned problems of the related art and to provide a sorting device which can increase the processing capacity without requiring a large installation space and is free from clogging. Is.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, in a fibrous substance sorting apparatus, a plurality of long fiber fraction aggregates are provided on the outer surface of a container at a position where the length of the sorting cylinder is within about 1.3 times the inner diameter of the sorting cylinder. The outlet and the fiber fraction inlet are provided alternately, the short fiber fraction aggregate outlet is provided on the outer surface of the container between the long fiber fraction aggregate outlet and the fiber fraction inlet, so that a plurality of sorting cylinders can be arranged, A rotary cylinder having a length corresponding to the axial length of a plurality of selection cylinders is arranged coaxially with the selection cylinder in the selection cylinder, which is a means for solving the problem. It is a thing.

[0005]

In the present invention, since the long fiber fraction aggregate outlet is provided at a position where the length ratio of the selection cylinder (length of the selection cylinder / diameter of the selection cylinder) is equivalent to that of the conventional structure, the long fiber component aggregate outlet is provided. The concentration increase of the aggregate does not become extremely large, and the probability of clogging of the selection cylinder does not increase. Further, since a plurality of sorting cylinders are provided, a large processing capacity per unit can be obtained, so that the number of facilities can be reduced and the installation space can be reduced. Further, the power consumption per unit processing amount can be reduced by the above-mentioned action.
