Description

  The present invention relates to an apparatus for separating waste or other mixed materials including clay, corros (shotgun shell after firing), lead bullets, plant pieces, pebbles, etc. generated in a clay shooting range.

  In the clay shooting range, clay, coros, and lead bullets generated by shotgun shooting are scattered on the ground. These scattered materials are collected and sent to the designated disposal site. However, during the collection work, plant fragments and pebbles growing on the ground are mixed. , Colos, lead bullets, plant pieces, pebbles, etc. are mixed.

  Therefore, the waste is separated into several types and then sent to a predetermined disposal site. These separation operations are performed by a manual operation using a sieve or the like. For this reason, a lot of labor and time are required for the sorting work.

  On the other hand, as a device for efficiently sorting a mixture of a plurality of articles having different sizes, shapes, materials, specific gravity, and the like, conventionally, sorting devices using wind power have been developed (see, for example, Patent Documents 1 to 3).

  As mentioned above, when manually sorting clay shooting ground waste containing clay, colosse, lead bullets, plant fragments, pebbles, etc., it requires a lot of labor and time and is inefficient. .

  On the other hand, although the sorting apparatus described in Patent Documents 1 to 3 is suitable for sorting work such as empty cans, empty bottles, bags, and garbage containing foamed synthetic resin, clay, corros, lead bullets, plant pieces It is not suitable for the separation work of shooting range waste mixed with pebbles. That is, in these sorting apparatuses, it is difficult to separate the shooting range waste in which lightweight items such as plant pieces and coros and heavy items such as clay, lead bullets, and pebbles are stacked one above the other.

  The problem to be solved by the present invention is that wastes and mixed materials including a plurality of types of components generated in a clay shooting range and the like can be efficiently separated into at least four types of components in a relatively short time. It is to provide a sorting device.

The separation apparatus of the present invention includes a sieving means for sieving a waste or a mixture containing a plurality of types of components, a first recovery means for recovering the first fraction that has passed through the sieving means, and the sieving Wind power that separates the second fraction that does not pass through the means, the third fraction that is floated by wind power, and the fourth fraction that is not floated by wind force. A second collection unit for collecting the third fraction, and a third collection unit for collecting the fourth fraction ;
As the wind force separating means, a blowing means for blowing air obliquely toward the second separated object from above the second separated object conveyed by the conveying means and in a direction opposite to the conveying direction of the second separated object. And suction means for sucking in the third fraction levitated by the blowing .

  By adopting such a configuration, the input waste or mixture is sorted by the size difference in the sieving means, and then sorted by the difference in mass and specific gravity in the wind sorting means. This sorting operation is performed continuously. For this reason, it becomes possible to classify | categorize and collect the waste and mixed material containing a multiple types of structure into 3 types, a 1st separated material, a 3rd separated material, and a 4th separated material, respectively. Therefore, the clay shooting range waste mixed with clay, colosse, lead bullets, plant pieces, etc. can be efficiently collected in a relatively short time, and the first fraction (lead bullets, small pieces, etc.), the third fraction (plant pieces, colosses). Etc.) and the fourth fraction (clay, pebbles, etc.).

Here, the as wind classification unit, more and this provided a blowing means for blowing air toward the second fractions to be conveyed by the conveying means, and a suction means for drawing the third fractions were levitated by air blowing, second It is possible to efficiently and reliably separate a plurality of types of components having different specific gravities contained in the separated product. For this reason, clay, corros, pebbles, plant pieces, etc. contained in the second fraction of clay shooting range waste are classified into third fraction (plant pieces, coloss, etc.) and fourth fraction (clay, pebbles). In this way, it becomes possible to sort efficiently and reliably.

  In this case, it is desirable to provide a blower that blows air obliquely from a direction opposite to the conveying direction of the second fraction as the blowing means. By providing such a blower, it becomes possible to blow air uniformly and accurately toward the second fraction conveyed by the conveying means, the floating action is also increased, and the second fraction is overlapped. Therefore, an excellent separation function can be obtained. In addition, if the mechanism which changes the ventilation capacity | capacitance of a blower is provided, the selection function according to the kind, property, etc. of a 2nd fraction can be set.

  On the other hand, if a cyclone is used as the suction means, the sucked third fraction can be further separated into two or more kinds of constituents and collected. Therefore, when the constituents are disposed or reused, respectively. Convenient. For this reason, it becomes possible to classify | categorize the 3rd separation thing (coloss, plant piece) of a clay shooting range waste into colosse and a plant piece.

  Here, if a vibrating sieve is used as the sieving means, the clay shooting range waste can be efficiently separated according to the difference in the sizes of the components. In addition, by using a vibrating sieve, plant roots, soil, and lead are crushed by the vibration of the sieve while the plant roots (plant fragments), soil, and lead bullets contained in the shooting range waste are adhered to each other. Since it can be separated into bullets, it has an excellent separation function. Furthermore, by changing the mesh size of the vibrating sieve, the sorting size can be set arbitrarily, so the sorting conditions corresponding to the situation of the clay shooting range waste containing multiple types of components are set. be able to.

  The present invention has the following effects.

As the wind force separating means, a blowing means for blowing air obliquely toward the second separated object from above the second separated object conveyed by the conveying means and in a direction opposite to the conveying direction of the second separated object. And a suction means for sucking in the third fraction levitated by the air blowing, waste and mixed substances including a plurality of types of components can be efficiently and relatively efficiently collected in a relatively short time. It becomes possible to sort into a fraction and a fourth fraction.

(2) By providing a wind blowing means for blowing air toward the second separated object conveyed by the conveying means and a suction means for sucking the third separated object floated by the blowing as the wind force separating means, the second separated object It is possible to efficiently and reliably separate a plurality of types of constituents having different specific gravities contained in.

(3) By providing a blower that blows air obliquely from the direction opposite to the direction in which the second fraction is conveyed as the blowing means, it is possible to blow the air equally and accurately toward the second fraction conveyed by the conveyance means. Because it becomes possible, the floating action is enhanced and an excellent sorting function is exhibited.
