Abstract

The sorting system according to the present disclosure is a sorting system for sorting crushed material generated by crushing a vehicle, and comprises a sieve installed above the conveying path of the crushed material, a first suction device that sucks up the crushed material from above the sieve and recovers the crushed material that has passed through the sieve as a first crushed residue, a blower that blows air onto the crushed material that has not been recovered by the first suction device, and a second suction device that sucks up the crushed material blown up by the air of the blower from above the conveying path and recovers it as a second crushed residue.

Description

Discrimination system, discrimination method, and control program The present disclosure relates to a separation system, a separation method, and a control program for separating shredded material generated by shredding a vehicle. In recent years, the recycling of ASR has been progressing. Consequently, there is a need to recover the shredded material generated by crushing vehicles by separating it with high precision into ASR containing useful metals and organic components such as hardened plastics. For example, Patent Document 1 discloses a method for treating a mixture of fragmented materials consisting of a small amount of used polymer material recyclable in the field of plastic technology and contaminants, which is generated by crushing the durable consumer goods at the end of the durability consumer goods' lifespan. Furthermore, there is a requirement to recover the shredded material generated by crushing vehicles with high precision, separating it into ASR containing useful metals and organic components such as hardened plastics. The present disclosure is made in consideration of the above background and aims to provide a separation system, a separation method, and a control program capable of separating and recovering shredded material generated by shredding a vehicle with high precision. The separation system according to the present disclosure is a separation system for separating crushed material generated by crushing a vehicle, and comprises a sieve installed above the conveying path of the crushed material, a first suction device that sucks the crushed material from above the sieve and recovers the crushed material that has passed through the sieve as a first crushing residue, a blower that blows air onto the crushed material not recovered by the first suction device, and a second suction device that sucks the crushed material blown up by the air of the blower from above the conveying path and recovers it as a second crushing residue. This separation system can improve the recovery rate of organic components included in ASR by using the blower and the second suction device to further recover organic components, such as hardened plastic, which could not be fully recovered by the first suction device alone. That is, this separation system can separate and recover the crushed material generated by crushing a vehicle with high precision. The blower is installed to spray air from the lower side of a tubular conveying path that conveys the crushed material not recovered by the first suction device from the upper side to the lower side of the conveying path, and the second suction device may be installed to suck from the upper side of the tubular conveying path. A control device for controlling each of the suction power of the first suction device, the suction power of the second suction device, and the wind power of the blower may be further provided. The above control device may be configured to control the suction power of the first suction device, the suction power of the second suction device, and the wind power of the blower, respectively, according to the components included in each of the first crushed residue and the second crushed residue. When the content of a predetermined metal in the first crushed residue and the second crushed residue is greater than or equal to a predetermined rate, the control device may weaken at least one of the suction force of the first suction device, the suction force of the second suction device, and the wind power of the blower. When the content of a predetermined organic component in the crushed material that is not recovered as the first crushed residue and the second crushed residue is greater than a predetermined rate, the control device may increase at least one of the suction power of the first suction device, the suction power of the second suction device, and the wind power of the blower. The separation method according to the present disclosure is a separation method by a separation system that separates crushed material generated by crushing a vehicle, wherein the crushed material is sucked from the upper side of a sieve installed above the conveying path of the crushed material, the crushed material that has passed through the sieve is recovered as a first crushing residue, wind is blown on the crushed material that is not recovered as the first crushing residue, and the crushed material blown up by the wind is sucked from the upper side of the conveying path and recovered as a second crushing residue. This separation method can improve the recovery rate of organic components contained in ASR by using a blower and a second suction device to further recover organic components, such as hardened plastic, which could not be fully recovered by the first suction device alone. That is, this separation method can separate and recover the crushed material generated by crushing a vehicle with high precision. The control program according to the present disclo
