Description

Budding sorting device, sorting system, and control program The present disclosure relates to a sorting device, a sorting system, and a control program for sorting Automobile Shredder Residue (ASR) recovered from shredded materials generated by shredding a vehicle. In recent years, the recycling of ASR has been progressing. Consequently, there is a need not only to separate the shredded material generated by crushing vehicles into ASR containing useful metals and organic components such as hardened plastics, but also to recover the ASR by separating it more finely. 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 need to not only separate the shredded material generated by shredding vehicles into ASR containing useful metals and organic components such as hardened plastics, but also to recover the ASR by separating it more finely. The present disclosure is made in light of the above background and aims to provide a buoyancy sorting device, a sorting system, and a control program capable of finely separating and recovering ASR recovered from shredded material generated by shredding a vehicle. The buoyancy sorting device according to the present disclosure comprises a tank containing water, an inlet for introducing crushed material into the tank, a water supply pipe for discharging water from an outlet located underwater within the tank, a guide that receives the water discharged from the outlet of the water supply pipe while underwater within the tank and generates an upward water flow in the water within the tank, a first outlet provided on the side of the tank, and a second outlet provided at the bottom of the tank. This buoyancy sorting device can finely separate and recover crushed material. For example, this buoyancy sorting device can finely separate and recover ASR recovered from crushed material generated by crushing a vehicle. Furthermore, this buoyancy sorting device can control the buoyancy of a predetermined crushed material by a water flow, and since there is no need to use saline solution or the like for control, corrosion of the device can be prevented. In addition, this buoyancy sorting device can perform wet buoyancy sorting of crushed materials using almost no power, so it can suppress the increase in costs. Also, since this buoyancy sorting device does not require a large-scale agitator, it can be miniaturized. The above guide may be formed by a part of the housing of the water tank having an inclined surface facing the above-mentioned outlet. The above guide may be formed in a downwardly convex arc shape so as to receive water ejected from the nozzle at one end and generate an upward water flow in the water ejected from the nozzle at the other end. The first discharge port may be provided near the water surface of the tank. The above-mentioned water tank may further be equipped with a stirring water wheel for stirring the water surface. The above stirring water wheel may rotate to stir the water surface of the tank in the opposite direction to the above first discharge port. The separation system according to the present disclosure is a separation system for separating Automobile Shredder Residue (ASR) recovered from shredded material generated by shredding a vehicle, and comprises an optical separation device for extracting metal components from said ASR and a floating separation device for separating resin contained in said ASR after metal components have been extracted by said optical separation device. The floating separation device comprises a water tank containing water, an inlet for introducing said ASR into said water tank, a water supply pipe for ejecting water from an outlet located underwater in said water tank, a guide that receives the water ejected from the outlet of said water supply pipe while underwater in said water tank and generates an upward water flow in said water tank, a first discharge port provided on the side of said water tank, and a second discharge port provided at the bottom of said water tank. This separation system is capable of finely separating and recovering shredded material. For example, this separation system can finely separate and recover ASR from the crushed material generated by crushing vehicles. In addition, since this separation system can control the buoyancy of the crushed material using a water flow, there is no need to use brine or the like for adjustment, thus preventing corrosion of the device. Furthermore, since this separation system can perform wet buoyancy separation of the crushed material using almost no power, it can suppress cost increases. Also, since this separation system does not require a large-scale agitator, it can achieve mi
