DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gypsum board processing apparatus for separating gypsum board into paper and gypsum.

2. Description of the Related Art Gypsum board is excellent in heat insulation and sound absorption,
It is often used as ceiling and wall materials, and a large amount of waste gypsum board is discharged at building demolition sites. After being dismantled, such waste gypsum board is discarded without treatment at a stable final disposal site (an industrial waste final disposal site in which the form of industrial waste does not change due to the action of nature). . By the way, gypsum is recognized as a stable type of industrial waste, but the paper on gypsum board is treated as a controlled type of waste (industrial waste whose form changes due to the action of nature) at the stable type final disposal site. Regulations have been tightening that waste is not allowed and must be disposed of in a managed final disposal site (an industrial waste final disposal site in which the form of industrial waste changes due to the action of nature). Therefore, it has become necessary to separate the waste gypsum board into gypsum and paper for processing. If the gypsum is separated into paper and gypsum, the separated gypsum can be reused. By the way, a gypsum board processing apparatus B that conventionally separates this type of gypsum board into paper and gypsum is configured as shown in FIG.

And crushed. Therefore, when the gypsum board is discharged from the granulator 20, the gypsum board is crushed by being squeezed to separate it into paper and gypsum. Gypsum board with paper isolated
The paper is conveyed to the sorter 6, shaken by the sorter 6, the gypsum passes through the net 6 a, the gypsum is discharged from the gypsum discharge port 11, and the paper that has not passed through the net 6 a is discharged from the paper discharge port 10. As described above, the gypsum board processing apparatus A of the present invention crushes the gypsum board, which has not been separated into paper and gypsum yet after the secondary crushing and remains at a predetermined particle size or more, into a predetermined size or less by the sizing device 20. And gypsum, it can be separated into paper and gypsum by the sorter 6, and the gypsum board of a predetermined size together with the paper does not pass through the net 6a of the sorter 6 and exits. This eliminates the problem of being discharged from 10. Note that the gypsum board processing apparatus A of the above-described embodiment is configured by the granulator 20 using the plate 22 as shown in FIG. 2, but a roller 31 is used instead of the plate 22 as shown in FIG. 3. May be used.
That is, the roller 31 is provided with a plurality of teeth 31 b on the surface, and the rotating shaft 31 parallel to the rotating shaft 21 a of the roller 21.
a in the direction of the roller 21 to move the roller 21 in the direction of the roller 21.
An elongated hole is provided in the case 25 on a straight line connecting 1a, and the rotation shaft 31a of the second roller 31 is movable on the elongated hole. The urging means (hereinafter referred to as a second roller urging means 3)
Say 2. ) To move and bias the second roller 31 in the direction of the roller 21, the shaft retainer 32 for pressing the rotating shaft 31 a.
a, and the column 32c (the column 32c is the case 25
It is fixed to. ) And the shaft retainer 32a.
A spring 32b is arranged via an adjustment bolt 32d attached to the member c so as to be adjustable in length. The second roller 3
A gap adjusting means (hereinafter referred to as a second roller movement restricting member 33) for moving and adjusting the first rotating shaft 31a in the direction of the spring 32b against the urging force of the spring 32b to provide a predetermined gap between the roller 21 and the second roller 31. ). The second roller movement restricting member 33 is provided with a shaft retainer 33a for holding the rotary shaft 31a via an adjustment bolt 33d attached to a column 33c (the column 33c is fixed to the case 25) so as to be adjustable in length. It is arranged on the support 33c. That is, the second roller movement restricting member 33 moves the second roller 3 only up to a predetermined gap position between the roller 21 and the second roller 31.
1 is restricted so as not to move in the direction of the roller 21. The gap between the roller 21 and the roller 31 adjusted by the second roller movement restricting member 33 is set to be equal to or smaller than the mesh interval of the net 6a of the separator 6. The gypsum board processing apparatus A according to the present invention provided with such a granulator 30 operates in the same manner as that provided with the granulator 20. In the following description of the operation, only the particle sizer 30 is different from the above-described embodiment. Therefore, only the operation of the particle sizer 30 will be described below. The secondary crushed gypsum board is bitten into the plurality of teeth 21b on the surface of the roller 21 and the plurality of teeth 31b on the surface of the roller 31 by the clockwise rotation of the roller 21 of the granulator 30.
Is supplied between the roller 21 and the second roller 31, and is supplied between the roller 21 and the second roller 31.
2 is pressed and crushed by the urging force of the spring 32b. Therefore, when the gypsum board is discharged from the granulator 30, the gypsum board is crushed and crushed, so that the gypsum board is separated into paper and gypsum. As described above, the gypsum board processing apparatus A using the granulator 30 also converts the gypsum board, which has not been separated into paper and gypsum after secondary crushing and has a predetermined particle size or more, still.
The paper is separated into paper and gypsum by being crushed to a predetermined size or less, so that it can be separated into paper and gypsum by the separator 6, and does not pass through the net 6 a of the separator 6 together with the paper. The problem that the gypsum board of the size is discharged from the outlet 10 can be eliminated. In addition, the granulators 20 and 30 provided in the gypsum board processing apparatus A of the present invention include:
Since it has an urging means, the granulators 20 and 3
When a foreign matter having a particle size equal to or greater than a predetermined value is mixed into the particle size 0 and the foreign matter is hard enough not to be crushed by the sizing devices 20 and 30, the urging means is used when the foreign material passes through the sizing devices 20 and 30. A predetermined gap is expanded in order to prevent foreign matter from passing therethrough. That is, the particle sizer 20,
30 is prevented from being damaged.

According to the gypsum board processing apparatus of the present invention, which is constructed and operated as described above, after the secondary crushing, the gypsum board which has not been separated into paper and gypsum yet has a predetermined particle size or more is reduced to a predetermined size or less by a granulator. Since it is crushed into paper and gypsum, it can be separated into paper and gypsum by a separator, and a gypsum board of a predetermined size together with paper without passing through the net of the separator Can be eliminated from the outlet.
