However, in the above-mentioned rotary waste sorter 100, the properties and shapes of long objects, wires, vinyl tapes and the like in the waste put into the rotary drum 101 are not specified. These long objects and the like are very easily caught in the large-diameter openings 111 among the openings provided on the sieve net, and the openings are frequently clogged. There is a point. For this reason, there is a problem that the sorting purity is reduced and a daily cleaning operation inside the apparatus is required.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and it is intended to prevent the clogging of the opening by the waste to be sorted, to improve the sorting accuracy and the plant operation rate, and to improve the cleaning. It is an object of the present invention to provide a rotary waste sorter capable of reducing the frequency.

[0010]

In order to achieve the above-mentioned object, a rotary waste sorter according to a first aspect of the present invention is provided with a rotary garbage sorter arranged in a downward slope from a waste input port to a waste input port. A small-diameter opening is provided on the input port side peripheral surface of the possible cylindrical rotary drum and a large-diameter opening is disposed on the discharge port side peripheral surface at predetermined intervals in the rotation direction and the rotation axis direction of the rotary drum. A rotary waste sorting apparatus configured to discharge and sort waste introduced into the rotary drum from the charging port through the small-diameter opening, the large-diameter opening or the discharge port by rotation of the rotary drum; At least two large-diameter openings adjacent to each other are communicated with each other at the end on the discharge port side in the rotation axis direction.

In the first invention, the waste put into the rotary drum from the charging port is moved to the discharge port side while being stirred by the rotation of the rotary drum, and during this time, the waste smaller than the size of the small-diameter opening is used. (Mainly non-combustibles) are taken into the small-diameter opening and collected, and waste (mainly medium-sized materials such as steel cans and aluminum cans) smaller than the size of the large-diameter opening is recovered. It is taken into the caliber opening and collected. Wastes (mainly combustibles) that move inside the rotary drum without being taken into the small-diameter opening and the large-diameter opening are collected outside from the discharge port. In this way, the waste put into the rotating drum is sorted into incombustibles, medium-sized materials, and combustibles.

In the first invention, the waste put into the rotary drum includes, for example, long objects and wires or the like having unstable properties and shapes. It may get caught in the aperture. The hooked long object or the like is wound between the large-diameter openings adjacent to each other in the rotation direction due to the rotation of the rotary drum. The long object wound between the large-diameter openings moves together with the waste moving in the rotary drum toward the discharge port, and the discharge-port-side end of the large-diameter opening in the rotation axis direction, that is, the large diameter. It is removed from the connection between the openings. The long object or the like thus removed is taken into the large-diameter opening and collected or returned to the rotating drum.

[0013] According to the first aspect of the invention, long objects and the like wrapped around the protruding member, which are factors causing the blockage of the large-diameter opening, are removed without stopping the sorting operation. It is possible to improve the rate and to reduce the frequency of cleaning.

Next, the rotary waste sorter according to the second invention is characterized in that a small-diameter is provided on the peripheral surface of the rotatable cylindrical rotary drum, which is disposed downward and inclined from the input port to the output port of the waste, on the input port side. An opening and a large-diameter opening are arranged at predetermined intervals in the rotation direction and the rotation axis direction of the rotary drum on the peripheral surface of the discharge port side, and the waste put into the rotary drum from the input port is disposed. In a rotary refuse sorting apparatus that discharges and sorts from a small-diameter opening, a large-diameter opening or a discharge port by rotation of a rotary drum, at least rearward in the rotation direction of the large-diameter opening, On the other hand, there is provided a winding prevention means having a sufficient length.

[0015] In the second invention, in the same manner as in the first invention, the waste put into the rotary drum is made of incombustible material, medium-sized material,
Sorted into combustibles. Properties such as long objects and wires contained in the waste in the large-diameter opening to sort the medium-sized objects
An unstable shape may be caught. This caught long object or the like tends to be wound between the large-diameter openings adjacent to each other in the rotation direction due to the rotation of the rotary drum,
The winding is prevented by the winding prevention means,
It is taken into the large-diameter opening and discharged from the rotating drum or returned to the rotating drum again.

According to the second aspect of the present invention, a long object or the like caught in the large-diameter opening is prevented from being wound around the large-diameter opening, so that the large-diameter opening is prevented from being blocked.
It is possible to improve the sorting accuracy of the waste and the operation rate of the plant, and to reduce the cleaning frequency.

Next, a rotary waste sorting apparatus according to a third aspect of the present invention is a rotary waste sorting apparatus in which a small rotatable cylindrical rotary drum is disposed on a peripheral surface of a rotatable cylindrical rotary drum disposed from a charging port to a discharging port. Large-diameter openings are arranged at predetermined intervals in the rotation direction and the rotation axis direction of the rotary drum at the aperture opening and the discharge port side peripheral surface, and the waste put into the rotary drum from the input port is disposed. In a rotary trash separation apparatus that discharges and sorts through a small-diameter opening, a large-diameter opening, or a discharge port by rotation of the rotary drum, at least rearward in the rotation direction of the large-diameter opening, And that at least two large-diameter openings adjacent to each other in the rotation direction are communicated with each other at an end on the discharge port side in the rotation axis direction. It is an butterfly.

In the third invention, the first invention and the second invention
Similarly to the invention, the large-diameter opening for sorting the medium-sized object may be caught by an object having an unstable property or shape, such as a long object or a wire, included in the waste. A long object or the like tends to wind around the large-diameter openings adjacent to each other in the rotation direction due to the rotation of the rotary drum, but the winding is prevented by the winding prevention means.
Further, even when the long object is wrapped between the large-diameter openings, the wrapped long object or the like moves along with the waste moving to the discharge port side in the rotary drum, and the large-diameter opening. It is detached from the end portion on the discharge port side in the rotation axis direction, that is, from the connection portion between the large-diameter openings. The long object or the like thus removed is taken into the large-diameter opening and collected or returned to the rotating drum.

According to the third aspect of the invention, a long object or the like caught in the large-diameter opening is prevented from being wound around the large-diameter opening or around the projecting member, and the long object or the like is placed on the projecting member. Even if it is wound, it can be removed without stopping the sorting operation. Therefore, it is possible to more reliably prevent the large-diameter opening from being blocked, thereby improving the sorting accuracy of the waste and the operation rate of the plant, and reducing the cleaning frequency.

In the second or third aspect of the present invention, the wrap prevention means projects radially outward of the rotary drum at an outer peripheral portion of the rotary drum and at one side in the rotation direction of the large-diameter opening. It is desirable to provide a protruding plate that does. By doing so, a simple structure can be obtained, and the above-mentioned effects can be surely obtained.
