Description of the Related Art Among construction waste materials, interior floor waste materials are classified into "waste plastics", and conventionally, they are crushed to a maximum diameter of 150 mm and disposed of by landfilling or the like. With the construction of the Construction Waste Material Recycling Law, it is obligatory to separate the materials at the construction site and it is necessary to recycle them by a method other than landfill.

In addition, a multi-layered tile carpet mainly made of PVC material as a backing material has been produced in an amount of about 20.4 million m 2 (Source: 1999, same as above).

んどである。Regarding these waste floor materials, as a method other than landfilling, a method in which various pulverizers are used to make fine powder and material is recycled again as a backing material such as floor material has been tried. The flooring material has a low melting point and contains a large amount of plasticizer, so it is soft, and in the high-speed pulverization process using the conventional shearing method or pressure crusher method, there is a phenomenon such as fusion phenomenon. Is likely to occur, and it is difficult to quickly pulverize it. Therefore, it requires a lot of energy and the device is large. By the way, most of the electric power for making 1 ton a particle diameter of about 3 mm exceeds 60 KW / hour.

The electric energy of 0 kW to 150 kW is required, and the device cost is high. Also, there is almost no fine crusher for PVC flooring materials.

The challenge is to realize a method to obtain fine powder that can be reused as a recycled material.

The pulverization is realized by the cutting force by a large number of rotating blades provided in the agitator (mixer) and the shear pressure generated when the ice is crushed,
In addition, this problem is solved by immersing the "waste floor material" in cold water to freeze it, and freezing it and then pulverizing it.

撹拌しつつ切断する。As shown in FIG. 2, the stirrer has a large number of blades attached to a uniaxial or multiaxial rotating shaft rotated by a motor, and pushes out ice and "waste floor material" sent by an extruding roller. The mixture is cut with a rotating blade while stirring.

The structure is such that when it reaches the grain size, it falls through the screen to the bottom.

である。The mixture of the "waste floor material" and ice, which has been cut and miniaturized by the stirring motion and the friction with the partition wall, is discharged through the above-mentioned screen, and falls on the discharge / conveyance belt.
After the water is squeezed out on the screen belt conveyor, the "waste floor material" powder is finished as a dry product in the dryer. Usually, it is difficult to convey fine powder at high speed because it is easily scattered, but it is easy to convey wet fine powder.

て有効である。The method of mixing and crushing the ice pieces and the "waste floor material" pieces according to the present invention is extremely suitable for pulverizing soft waste materials such as vinyl chloride-based waste materials and thermoplastic resin waste materials which are easily fused at a high speed. It is valid.
【００１６】その効果の一つは、氷片による発熱の防止
であり、二つ目には、氷片の破砕時に発生するせん断お

省エネである。Ice pieces are continuously mixed at a weight ratio of 0.3 with respect to the waste floor material 1 and a large number of cutting edges are rotated at a high speed of about 1000 rpm to obtain 1,000 k / hour.
The amount of power required to pulverize 1 g of waste floor material to a particle size of about 500 microns is about 40 to 45 kW even if the power for producing ice pieces is taken into consideration, which is much more energy saving than conventional methods. is there.

水分が氷結することにより、容易に粉砕が可能となる。Further, as shown in FIG. 1, a method of immersing a piece of "waste floor material" in cold water and blowing cold air at -10 ° C. or less to freeze instantaneously is also very effective.
By frosting the water content or the water content on the surface or inside of the "waste floor material" pieces, it becomes possible to easily pulverize.

ある。Usually, when water becomes ice, the volume increases by 10% or more. Therefore, due to the water content inside, the waste floor material is likely to be crushed from the inside by the wedge effect, and the crushing in combination with the fine ice pieces is even more effective.

Chemical fibers used for carpets such as nylon fibers and acrylic fibers are extremely expensive, after undergoing the step of pulverizing the fiber portion of the waste flooring material, again mixing with each virgin powder, melting, spinning, It is used again as a surface material such as floor material. Alternatively, it can be used as a binder for laminating different fiber materials.
【００２２】繊維が長繊維の場合は、溶融工程におい

これは、塩ビ再生原料についても同様のことが言える。When the fibers are long fibers, the finished product is often hindered by the inclusion of air in the melting process, so it is desirable to make the fibers as fine as possible.
The same can be said for PVC recycled raw materials.

A frozen fiber sheet composed of fiber pieces having a length of 3 to 5 mm is cut using a rotary tool having many cutting edges at 0.5 mm intervals as shown in FIG.
【００２６】通常極短繊維は、そのままの状態では、飛

The frozen fiber sheet having an appropriate hardness is an optimal material for continuous ultrasonic cutting because it prevents the ultrasonic oscillator from generating heat and enables continuous ultrasonic oscillation. The horn holds many cutting edges and is driven up and down at high speed to perform ultrasonic cutting. (Not shown)

言うまでもない。As a method of pulverizing a vinyl chloride waste floor material to obtain a good quality raw material for regeneration, freezing or mixing with an ice piece,
It goes without saying that the method of pulverizing is not limited to vinyl chloride waste floor material and fiber waste floor material, and can be applied to pulverization of thermoplastic resin.

When pulverizing PVC waste floor material, mix ice pieces with the "waste floor material" pieces and cut or crush them, and freeze "waste floor material" containing water by cold air to cut or crush. Is extremely energy-saving, and it is possible to realize the pulverization of waste flooring materials that is optimal for recycling.
