Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing method for processing a discarded tire by shearing a tire piece and separating a wire contained in the tire piece from a rubber portion.

2. Description of the Related Art Conventionally, when processing a recycled product for reuse, the waste tire is cut into several pieces of tires as a pretreatment step and then finely crushed by a crushing device. For example, as shown in FIG. 30, for example, the crushing blades C1 and C2 of the crushing device generally convert the waste tire piece T10 into the crushed piece T1.
A method of cutting into 0a and T10b is known. Wire W such as a belt wire included in waste tire piece T10
Is cut simultaneously with the cutting of the rubber portion. Fragment T10
a, Wire W remains in T10b. In this way, the crushed pieces of the waste tire once crushed by the crushing device are repeatedly crushed until the wire is removed from the crushed pieces to about several millimeters because the wire is contained therein, and finally, The rubber is separated from the wire by making it into a chip shape. The reason for crushing finely is that if the wire W is contained in the rubber, the quality of the recycled product (rubber as a raw material) is deteriorated. It is desirable that the reclaimed product does not include wires in rubber as much as possible.

According to the prior art, the number of times of crushing is inevitably increased for the final treatment of the crushed pieces. As a result, the crushing operation is troublesome, the crushing blade is consumed, and the processing time is reduced. There was a problem that the cost was high and the size of the crushed pieces was too small to limit the field of reuse. An object of the present invention is to reduce the number of times of crushing and to easily separate a wire contained in a waste tire from a rubber portion.

SUMMARY OF THE INVENTION The present invention relates to a method for treating a waste tire having a wire by a first crushed body and a second crushed body each having a separate crushing blade. There is a gap between the blade portion of the separation and crushing blade and the blade portion of the separation and crushing blade in the second crushed body so that waste tire pieces can enter. The tire piece is sheared while being pulled toward both blade portions as the first crushed body and the second crushed body move in the opposite directions, and the wire is separated from the rubber portion. The waste tire pieces are typically crushed pieces crushed by a separation crushing blade, but depending on the crushing state, a part of the crushed pieces, a part of which is connected to a crushed object that cannot be completely crushed, included. When crushing the waste tire piece, the first crushed body or the second crushed body may be rotatable in a direction in which one is opposed to the other, or may be movable along a blade. The blades that cooperate to treat waste tire pieces form grooves that allow some of the waste tire pieces that have entered the gaps between the blades to bite in order to make separation and crushing effective. I have.

The waste tire pieces entering the gaps between the blades of the separating and crushing blades are subjected to forces opposite to each other on the cut surface of the waste tire pieces during shearing. Can be separated.

BEST MODE FOR CARRYING OUT THE INVENTION Waste tires
After being cut into multiple pieces of the size, it is shown in the figure
It is processed by the processing method. This processing method is shown in FIG.

Although there are various postures and states of 0, three cases are typical.
An example will be described. First, the first case shown in FIG.
Will be described. Waste tires are cut into several pieces in advance
Cut pieces move in opposite directions relative to each other
Crushed into several pieces by crushing blades 409b and 410b,
As shown in FIG. (A), the waste tire pieces T1 that have become crushed pieces
0 enters the gap 413, and both sides of the waste tire piece
417a is also bitten into the compressed state
Hangs). In this case, the separation crushing blade 409
b and 410b are in the process of moving in opposite directions
The blades 409b1 and 410b1 gradually approach and face
Eventually, they gradually separate. Blade portions 409b1, 410b
In the process of moving away from each other,
The both sides of the waste tire piece T10 are pulled in opposite directions.
And two waste tire pieces, namely, crushed pieces T11 and T12.
At the same time as these pieces
The broken wire W is separated (FIG. B). In this way,
Cutting and separation are performed, and cutting and separation are performed by the upper groove 417a.
Separation is performed more effectively. In this case,
The waste tire piece T10 cut from the cut body will be described.
However, one that is connected without being separated from the cut body
The gap 4 is also used for waste tire pieces that are part of
13 and the groove 417a.
Goes. Next, the second case shown in FIG.
I will tell. As shown in FIG. 2A, the waste tire piece T10 is
It enters the gap 413 between the separation and crushing blades 409b and 410b.
Only when it is pressed into the groove 417a
is there. In this case, the separation crushing blade 409b and the separation crushing blade
