Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention treats refuse that is light and flexible, such as household incombustibles in vinyl bags and paper bags, and substances with relatively high specific gravity, such as glass bottles and empty cans. It relates to the device.

[0002]

2. Description of the Related Art Conventionally, as a method for separating and selecting those having different specific gravities as described above, first, a bag is broken by a bag breaking machine to take out glass bottles, empty cans, etc. is doing. In such a wind power sorter, an air outlet and a suction hood for sucking air are opposed to each other, and a substance to be sorted is passed between them to separate a light substance sucked together with air and a heavy substance not sucked. is there. In this case, a means is used in which the substance to be sorted is allowed to drop by its own weight or is fed substantially horizontally by a vibration conveyor or the like.

[0003]

In the conventional wind power sorting apparatus as described above, the method in which the substance to be sorted is dropped by its own weight has a high speed of passage of the substance, and the mass of the substance to be sorted is not loosened. In addition, the sorting performance is poor, and when a vibrating conveyor is used, there are drawbacks such as the outlet being clogged because the substance to be sorted directly passes over the outlet and heavy substances falling to the outlet. There is. Further, since air unnecessary for selection is sucked from the supply part and the discharge part of the substance to be selected, it is necessary to increase the amount of suction air from the suction hood.

Further, in the bag breaking machine, there has been a problem that a broken vinyl bag or the like winds around the bag breaking blade and interferes with the rotation of the bag breaking blade.

In order to solve the above-mentioned problems of the conventional apparatus, the object of the present invention is to crush bags and crush cardboard boxes with a single device and separate heavy and light specific gravities, Another object of the present invention is to provide a bag-breaking / separating device that automatically removes a vinyl bag or the like wound around a bag-breaking blade.

[0006]

In order to solve the above-mentioned problems, the present invention has an inlet for an object to be treated in front of the upper portion, an outlet for an object having a large specific gravity in the lower portion, and an upper rear portion. A first shaft and a second shaft each having a bag-breaking blade on the outer periphery are provided in a bag-breaking chamber having a suction port for a material having a lighter specific gravity, and the first shaft is between the charging port and the suction port and the second shaft. Are arranged so that they are closer to the front of the input port, both shafts are mutually inward toward the input port, and the rotation speed of the first shaft is faster than that of the second shaft so that Is provided with a third shaft, and the third shaft is rotated in a direction opposite to the first shaft at a faster speed than the first shaft, and the third shaft is provided on both sides of the bag breaking blade of the first shaft. A rotating plate that contacts and discharges the flexible material wrapped around the bag-breaking blade toward the suction port is fixed, and the suction port leads to the cyclone separator at the suction port. It was connected.

[0007]

The present invention has the above-mentioned structure, and while the air in the bag-breaking chamber is sucked from the suction port by the operation of the cyclone separator, a can, a glass bottle, and other household incombustibles are put in a vinyl bag, When a processed material that has a mixture of lighter specific gravity such as a vinyl bag or paper bag and a relatively higher specific gravity such as a glass bottle or a can is put into the bag breaking chamber through the charging port, the breaking blades of the first and second shafts Vinyl bags and corrugated cardboard are torn by the blades that are caught between them and have different rotation speeds.

The thus torn material having a low specific gravity is wound up by the bag-breaking blade of the first shaft which rotates at high speed, and is sucked into the suction port together with the air flow. On the other hand, glass bottles, iron cans, aluminum cans and the like having a high specific gravity fall into the discharge port from between the first shaft and the second shaft. Also, a part of a flexible material such as a vinyl bag is wrapped around the shredding blade of the first shaft, but this wrapped material is scraped up by the rotating plate rotating at a higher speed and removed. And inhale into the suction port.
