Description

  The present invention relates to an air dynamic water sorter that uses the flowing water class and settling speed of crushed industrial waste after magnetic metal removal, and provides homogeneous solid valuables and smooth economy through automation control. The present invention relates to a sorter that uses a flowing water class and a sedimentation speed, which is suitable for moving the water.

  Therefore, in the separation treatment technology, the air / water sorter has been a specific gravity sorting technology for coal preparation and mineral processing. In recent years, air and water sorting has been reconsidered from the field of environmental chemical technology for treating crushed industrial waste instead of coal and ore. As an indispensable issue for a sustainable economic society with low environmental impact, crushing industrial waste processing and sorting machine using liquid is a low-cost and low-load separation processing means, contributing to resource reuse and environmental problems. It is a technology that can be done.

  However, unlike coal and ore, crushing industrial waste is a solid waste that is a mixture of various articles and materials, even a solid crushing industrial waste from which the magnetic metal of a scrap vehicle has been removed. When sorting these composite wastes into effective recycled materials, there are a mixture of “hard floats”, “soft floats”, “intermediate floats” and “falling nets”. ), Polypropylene (hereinafter referred to as “PP”), polyethylene (hereinafter referred to as “PE”), polystyrene (hereinafter referred to as “PS”), acrylonitrile butadiene styrene resin (hereinafter referred to as “ABS”), poly Various types such as vinyl chloride (hereinafter referred to as “PVC”), “wood”, “rubbers”, “stone”, “glass”, “substrate waste”, “painted film”, “fiber waste”, “copper wire waste”, “stainless steel”, “aluminum”, etc. The material is mixed. The mixing ratio of these composite wastes is indefinite and changes sequentially.

  In the water sorting of complex wastes of various materials that change indefinitely and sequentially, it is necessary to repeat sorting in the sorting tank up to the target material, and sorting tanks with different sizes, shapes, and processing capabilities are also required. . In addition, in order to improve the processing capacity efficiently, it is necessary to sequentially adjust the input amount of composite waste, the flow amount of the treatment solution to the sorting tank water, and the air intake and exhaust amount of the air chamber to each sorting tank. It could not be realized by using separation and separation technologies for coal preparation and mineral processing.

In Japanese Utility Model Publication No. 63-039440, a diaphragm-type jig beneficiation machine is disclosed in which the number of impulses of the diaphragm can be adjusted by an inverter, and a makeup water valve and a concentrate discharge valve are electrically linked. No reference is made to means for detecting the pulsation of sorting.
In Japanese Utility Model Publication No. 63-098735, a fixed net type jig sorter for a diaphragm jig tank in which a fixed net is obliquely installed, a specific gravity change surface detection device in which a float is suspended is installed to control the rotation speed of the scraping blade. However, it does not control the water supply or the input of ore.
Japanese Patent Application Laid-Open No. 01-164456 discloses a method for selecting pulsation specific gravity of various crushed materials such as minerals, household goods, and automobiles, but since specific control means are not mentioned, it is particularly useful for households. It is difficult to select pulsation specific gravity of various crushed materials such as automobiles.
Japanese Patent Laid-Open No. 2003-38981 discloses detection means for detecting the composition of the discharged matter, and discloses a means for driving and controlling the discharging means by a color image extraction device for imaging the discharged matter. It does not control pulsation.
JP 2004-58032 A discloses a pulsating bubbling tank in which bubbles are intermittently discharged by a specific gravity sorter using a wet method for classifying plastics and metals from shredder dust. There is no explanation.

  From the above, it is a detection means that can immediately respond to pulsations in individual sorting tanks with different sizes, shapes, and processing capacities for sorting tanks, with respect to the mixed changes of mixed waste that is crushing industrial waste, It has been extremely difficult to realize a sorter that uses the flowing water class and settling velocity by controlling the air intake / exhaust volume of the air chamber, the flow rate of the treatment solution flow, and the input volume of the composite waste.

  With reference to FIG. 7, the best mode will be described along a flowchart showing an embodiment of all the steps of the present invention. The present invention is an ELV (End of Life Vehicle) (hereinafter referred to as “appropriate treatment dismantling”), which enables a subsequent vehicle to be properly selected and processed by ASR (shredder dust) (hereinafter referred to as “crushing industrial waste”). A blunt in parallel with the processing is also conceivable.

  First, step S-1 is a step of crushing a vehicle, which is a solid object dismantled properly, with a crusher. In this process, composite waste containing various materials is crushed to about 0.1 mm to 40 mm. In the composite waste, magnetic metal and non-magnetic metal are mixed, but it is possible to easily remove the magnetic metal from the composite waste crushed by the crushing step with a magnetic separator. For crushing industrial waste after removing magnetic metal, "urethane" "PP" "PE" "PS" "ABS" "PVC" "wood" "rubber" "stone" "glass" "substrate scrap" "painting" There are various materials such as membrane fiber “fiber waste” “copper wire waste” “stainless steel” “aluminum”. The mixing ratio of these composite wastes is indefinite and changes sequentially.

  Therefore, in step S-1, in addition to crushing and removal of the magnetic metal, in addition to transporting to the sorting tank (12), a transport stirring means (36) is added.

In 36), the input amount of the crushed industrial waste charged into the sorting tank (12) is adjusted. Alternatively, when it is necessary to reduce the processing capacity of the sorting tank (12), the air valve unit (13) reduces the air amount and the flowing water adjustment valve unit (20), and the liquid stirring amount (36) may be reduced. ) To adjust the input amount of the crushed industrial waste to be input to the sorting tank (12). In addition, since the pulsation detecting means (6) is suspended in all the sorting tanks (12) in each step of separating and sorting specific gravity according to the present invention, it is possible to centrally control the entire processing capacity. Become.

  In step S-3, the “soft suspended matter” is further separated by a two-tank air / water sorter (23) in which a plurality of pulsation detecting means (6) are suspended from a plurality of sorting tanks (12) shown in FIG. “PE” is separated and sorted by specific gravity. “Urethane”, “PP”, and “wood” are molded by a compression molding machine after dehydration and can be processed into a high-calorie solid fuel (Refuse Paper and Plastic Fuel) (hereinafter referred to as “RPF”). .

  In step S-4, the “hard floating matter” is separated by a two-tank air / water sorter (23) in which a plurality of pulsation detecting means (6) are suspended from a plurality of sorting tanks (12) shown in FIG. Specific gravity is separated and sorted into PVC and rubber. Furthermore, “re-hard floating matter” is generated.

  In step S-5, the “re-hard floating substance” is divided into a plurality of sorting tanks (12) shown in FIG. 4 by a two-tank air dynamic water sorter (23) in which a plurality of pulsation detecting means (6) are suspended. Sorted into “ABS” and “PS”.

  Step S-6 is a two tank air dynamic water sorter (23) in which a plurality of pulsation detecting means (6) are suspended from a plurality of sorting tanks (12) shown in FIG. Specific gravity is separated and sorted into “glass”, “substrate material”, “painted film” and “fiber waste”.

  In step S-7, “intermediate suspended matter” is separated by a two-tank air dynamic water sorter (23) in which a plurality of pulsation detecting means (6) are suspended from a plurality of sorting tanks (12) shown in FIG. Specific gravity separation and sorting into stone, glass, and substrate waste.

  Step S-8 is "intermediate suspended matter" "Stainless steel" "Aluminum" by the one tank air dynamic water sorter (22) which suspended the pulsation detection means (6) in the sorting tank (12) shown in FIG. Specific gravity separation and sorting.
