The system for separating and collecting glass particles according to the present embodiment has the above-described configuration and is used in the following manner.

First, a glass bottle is put into the hopper 12 of the primary crushing unit 10. In addition, the glass bottle to be thrown in is manually separated in advance, and only the glass bottle of a certain color is thrown in, so that the finally collected glass grains can be used as a pavement aggregate having a decorative effect.

Then, the glass bottle put into the hopper 12 is crushed into round glass particles by the primary crushing unit 10 and the secondary crushing unit 16 (crushing step), dust and the like are removed by the cyclone 22, Thereafter, it is sent to the sorting machine 25 for return. As described above, since dust and the like are removed by the cyclone 22 before being sent to the return sorting machine 25, clogging of the return sorting machine 25 can be prevented.

Further, the crushed material having a particle size of 5.0 mm or more is returned to the secondary crushing unit 16 through the return path 29 in the return separation device 25 (return separation step). At this time, in the return path 29, the impurities composed of irons and the impurities composed of non-ferrous metals are removed by the non-ferrous metal removal device 39, and the impurities such as paper are removed by the return wind separation device. As described above, the crushed material having a certain particle size or more is returned through the return path 29 and crushed again, so that the entire glass bottle can be effectively reused. Moreover, since the crushed material returned in the return path 29 has already been subjected to secondary crushing, impurities can be reliably removed by the non-ferrous metal removing device 39 and the return air separation device 42. In other words, it is conceivable to remove impurities in the crushed material having a certain particle size or more separated after the coarse crushing by the primary crushing unit by using a non-ferrous metal removing device. In such a case, the crown and the like remaining on the neck and the like of the glass bottle are often integrated with the glass bottle as it is, so that impurities such as the crown and the like cannot be reliably removed. In comparison,
After crushing the material to be crushed into glass particles as in the present embodiment, sorting and returning are performed, and impurities such as crowns are removed in the return path, whereby removal of impurities in a state separated from glass particles is more facilitated. It has the advantage that it can be performed reliably.

The particle size of the particles separated by the return separator 25 is 5.
The crushed material having a size of 0 mm or less is separated into three types of crushed material by the collection separator 52 via the transfer path 50 (collection separation step), and stored in each storage container 61 through each discharge path 60. (Collection process). In the collecting step, the particle size is 0.6 m
Unloading route 60 for crushed materials of m to 2.0 mm and particle size 2.0 m
The self-weight drop section 65b
Is formed, and impurities such as paper are removed by the wind facing the falling direction when the crushed material passes through the carry-out path 60. In particular, since the crushed material in the carry-out path 60 has already been separated according to the particle size by the separation means B, the wind force is set by each wind control valve 69 according to the glass particle having the particle size. It is possible to remove impurities with high accuracy. Further, when the crushed material falls at the dead weight dropping portion 65b, the impurities in the crushed material and the glass particles are easily separated from each other, so that the impurities can be more reliably removed by the facing wind.

The container 61 containing the glass particles is pulled by the hoist 70, and a predetermined amount of the glass particles is packed by the next bagging device 71.

Since the glass particle sorting and collecting system of this embodiment is used by the above-mentioned use method having the above configuration, it has an advantage that glass particles corresponding to the particle diameter can be collected in a state with few impurities.

Further, since the same blower 45 as the two wind separation means 67 provided in each carry-out path 60 can be used as the blower 45 of the return wind separation device 42, the cost of the system itself can be reduced. It has the advantage that it can be done.

Further, since the wind force adjusting valve 69 of the wind power selecting means 67 of the carry-out path 60 can appropriately adjust the wind force, the wind force of each carry-out path 60 is adjusted each time according to the purpose of use of the collected glass particles. By doing so, the reliability of the removal of impurities can be increased or the efficiency of the collection operation can be increased depending on the purpose of use.

Further, since there is a transport path 50 for transporting the crushed material crushed by the crushing device A to the collecting separator 52, the crushing device A and the collecting separator 52 can be installed at desired locations. Further, the return path 29 having a desired distance can be provided by setting the installation location of the return separator 25 in accordance with the return path 29.

The system for separating and collecting glass particles according to the present embodiment has the advantages described above because it has the above-mentioned configuration and is used like the method for separating and collecting glass particles, but the present invention is not limited to this. Not.

That is, in the above-described embodiment, the crushing apparatus A is composed of two crushing units, the primary crushing unit 10 for performing coarse crushing and the secondary crushing unit 16 for performing fine crushing. There is no limitation, and the design can be changed as appropriate as long as the device can crush a glass bottle into glass particles.

In the above embodiment, the separating means B
Has been described that includes the collection separator 52, the transport path 50, the separator 25, and the return path 29, but in the present invention, the crushed material crushed by the crusher A is separated and returned according to the particle size. The transport path 50 and the like are not essential requirements.

Further, in the above-described embodiment, the case where the crushed material is returned to the secondary crushing unit 16 by the return path 29 has been described. However, in the present invention, the crushed material separated by the separation means B is returned to the crushing device A. Any method may be used as long as it is returned to the primary crushing unit 10, for example, within the scope of the present invention.

In the present invention, the provision of the non-ferrous metal removing device 39 and the return wind separation device 42 in the return path 29 is not an essential requirement, and instead of the non-ferrous metal removing device 39,
For example, as shown in FIG. 3, an iron removing device 37 such as a suspended magnet may be provided. However, in the present invention, as in the above embodiment, a non-ferrous metal removing device 39 capable of separating crushed materials into three types other than iron, non-ferrous metal, and metal is provided on the return path.
If provided in 29, there is an advantage that impurities such as aluminum and iron can be removed, and these impurities can also be separated and collected into aluminum and iron.

Further, when the crushing device A is composed of the primary crushing unit 10 and the secondary crushing unit 16, the crushing unit A is returned to the secondary crushing unit 16 by the return path 29, as shown in FIG. It is also possible to return it to 10.

The present invention is not limited to the above-described embodiment in which the glass particles are stored in the storage container 61. For example, a conveyor for transporting the glass particles separated by the separation means B to the next step, etc. Even so, it is within the range intended by the present invention.

Then, impurities such as iron or aluminum in the crushed material returned in the return path can be removed by the irons removing device or the non-ferrous metal removing device, thereby collecting the glass particles with less mixed impurities. In particular, since the ferrous material removing device or the non-ferrous metal removing device removes impurities in the crushed material already crushed by the crushing device, there is an effect that the removing operation can be surely performed.

Further, the glass particle sorting and collecting system according to the second aspect of the present invention can remove impurities such as paper in the crushed material of the return path by the wind force of the return wind separation means, and the mixed impurities are less. Since the glass particles can be collected, and particularly the impurities in the crushed material already crushed by the crushing device are removed at the falling part of the return path, it is possible to remove the impurities more reliably.
