Also, the present invention relates to a method of recovering metal pieces, pulverized vinyl chloride / rubber, and iron powder from automobile molding waste separated into iron powder.

[0002]

2. Description of the Related Art Conventionally, as a document for separating and collecting molding waste into reusable metal pieces and plastic pieces, Japanese Patent Application Laid-Open No.
No. 7796 has a method and an apparatus for recovering metal pieces from shavings. The composition is to supply the mill waste to the crusher, shred it to a long side particle size of almost 100mm to 5mm to make fine pieces, supply it to the magnetic separator, separate it into metal pieces and plastic pieces, and make it to the wind separator. The metal pieces are supplied and sorted into finely selected metal pieces and dust, and the object is to recover high-quality metal pieces from molding waste.

[0003] As a reference for separating and recovering pulverized vinyl chloride / rubber and iron powder, there is a waste tire pulverizing apparatus disclosed in JP-A-54-99261. Its configuration consists of a coarse grinding wheel that grinds the compressed waste tire, a water tank equipped with a scraping conveyor that floats and separates this crushed product into iron powder and crushed rubber, and a crushed rubber that has been separated in specific gravity. An object of the present invention is to collect a reusable comminuted rubber, which comprises a dryer for drying and an airflow separating means for separating dust from the comminuted rubber.

[0004] As another literature for separating and recovering vinyl chloride, there is a method for separating and recovering composite material waste disclosed in Japanese Patent Application Laid-Open No. Hei 3-30877. The composition is to reduce the composite waste by setting the distance between the fixed blade and the rotary blade to the thickness of the layer with the highest specific gravity of the composite material.
It is configured to pulverize with a cutter mill with a size of 100 to 300% and classify the mixed and crushed material of each obtained material according to the difference in specific gravity. It is to plan.

[0005]

The above-mentioned Japanese Patent Application Laid-Open No. 5-7796 exemplifies a conventional shredder, hammer mill or the like as a crusher. However, according to the experience of the present applicant, a high quality metal piece is used in the crusher. There are some problems in crushing and separating. That is, a crusher is required which employs a configuration such as fine adjustment of the gap between the damper (or the inner wall surface of the casing) and the hammer (blade). However, according to the invention of the literature, the above configuration is not adopted, and it is unlikely that a high quality metal piece is recovered as expected. Further, in the present invention, there is also a problem that the post-treatment of the plastic pieces is not sufficiently considered. In addition, this document relates to separation, sorting, and collection of plastic pieces, which is different from the separation, sorting, and collection of the crushed vinyl chloride and rubber of the present invention.

Japanese Patent Application Laid-Open No. 54-99261 discloses flotation separation,
Employing airflow separation is somewhat similar. But,
As in the present invention, crushing and separation of molding waste or vinyl chloride
It does not cover the separation, sorting, and recovery of rubber crushed materials, and has a different purpose. In addition, the invention of the literature is a configuration in which flotation separation and airflow separation are performed after pressing and grinding. Therefore, the recovery of metal pieces, crushed vinyl chloride / rubber, and iron powder from molding waste, which is the target of the present invention, cannot be expected at all.

Further, JP-A-3-30877 has a similar structure for separating and recovering vinyl chloride. However, there is substantially the same difference from the present invention as in the above-mentioned JP-A-54-99261.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The recovery method of the present invention will be described. First, the crush separation of the molding waste will be described. The molding waste is sent to the supply casing by a transporting means (conveyor). The molding waste supplied to the supply casing is supplied to the shrettle casing shown in FIGS. 1 to 4 by a predetermined amount. Thereafter, the molding waste is scooped up by a high-speed rotating shattering drum and a hammer, and by the high-speed rotation of the shattering drum, an intermediate wall surface (a wall surface on which a liner is attached) of the shredding casing, and a pair of swingable shattering dampers ( (Hereinafter, simply referred to as a Schletter damper.) It is crushed by crushing, but ultimately it is squeezed in a mm-unit gap formed between the intermediate wall that oscillates in mm units and the hammer of the Schletter drum. You. This gap size is with metal pieces and iron powder.
Compressed dimensions of mixed vinyl chloride and rubber pieces, and mm
Metal fragments and vinyl chloride / rubber fragments with and mixed with iron powder are manufactured. In addition, depending on the swinging position of the intermediate wall and the Schletter damper, metal pieces and iron powder
It directly affects the efficiency of separation from contaminated vinyl chloride / rubber pieces (hereinafter, in principle, metal pieces, etc.), or the size of crushed metal pieces, etc. That is, by the operation of bringing the intermediate wall surface closer to the hammer of the Schletter drum, it is possible to expect an improvement in the separation efficiency and a fragmentation of the crush size.

[0013] As described above, the metal piece or the like having the predetermined size passes mainly through the mesh of the upper Schletter damper, is guided to the delivery passage of the Schletter casing, and is stored in each case. You. It is also possible to adopt a configuration in which the gap between the lower part of the pair of shutter dampers and the hammer is adjusted in units of mm to reduce the impact on the intermediate wall surface or to further subdivide it.

On the other hand, the metal crushed lump and the non-metal crushed lump that cannot pass through the mesh of the upper Schletter damper fall from the space between the intermediate wall surface and the hammer of the Schletter drum toward the bottom of the crushing chamber of the Schletter casing, It is scooped up by a Schletter drum and a hammer, and the subsequent processing is as described above. Accordingly, the injected molding waste is crushed / separated and separated into metal pieces and the like, but the above-described operation and procedure are repeated until crushed / separated into metal pieces and the like having a predetermined size.

The metal pieces crushed by the above operations and procedures are reused as raw materials for steelmaking. On the other hand, since iron powder is often attached or mixed into the vinyl chloride / rubber pieces, the pieces are again pulverized and separated.

Next, the pulverization and separation of vinyl chloride / rubber pieces with / with iron powder will be described. The vinyl chloride / rubber pieces with / with iron powder are put into a pulverizer shown in FIG. The vinyl chloride / rubber pieces with or mixed with iron powder are pulverized by a blade such as a cutter mill, a roller mill, or another pulverizer, and separated into a pulverized vinyl chloride / rubber material with iron powder and an iron powder material. The crushed vinyl chloride / rubber material with iron powder and the iron powder material are fed into a hopper and then supplied to a vibrating sieve at a predetermined amount. The vibrating sieve machine is used to sift the iron powder from the crushed PVC / rubber material with iron powder by using several meshes having different meshes, and the crushed PVC / rubber material with iron powder and iron Dust adhering to the powder material is separated, and the dust is guided to a dust collector (not shown). By this vibrating sieve, the separated treated vinyl chloride / rubber crushed material and iron powder material are guided to a wind separator. Separation of treated PVC / rubber crushed material and treated iron powder material using the wind separator of this wind separator, and removal of dust adhering to treated PVC / rubber crushed material and treated iron powder material Separation is performed, and the separated dust is guided to a dust collector (not shown). On the other hand, the reprocessed vinyl chloride / rubber crushed material and the iron powder material which have been processed by the wind separator are guided to a water flow / floating separator of a specific gravity separator. The first water flow sorter uses the inclined surface and the water flow to wash away the reprocessed vinyl chloride / rubber crushed material and the iron powder material and to jet the remaining dust. The jet scattered dust is guided to a dust collector. On the other hand, the flowing reprocessed vinyl chloride / rubber crushed material and the iron powder material are guided to a flotation sorter and separated by specific gravity. That is, the reprocessed iron powder material settles, and the reprocessed vinyl chloride / rubber material material floats. The sedimented reprocessed iron powder material is guided to a washing and dehydrating machine by a transport screw provided in a flotation sorter, and then dried and collected to become a reusable iron powder material, which is measured and the like. On the other hand, the floated reprocessed PVC / rubber pulverized material is guided out of the machine sequentially by transport rollers equipped in the flotation sorter, collected in the PVC / rubber pulverized material storage case, and then washed and dewatered. It is led and washed and dewatered. Thereafter, it is dried and collected to obtain a reusable pulverized vinyl chloride / rubber product, which is measured and the like. The sediment settled on the bottom of the flotation sorter is returned to the water flow sorter. In addition, the sewage of the flotation separator is guided to a sedimentation tank (not shown), where it is settled and separated, and then used for the water separator. The sediment is separated or discarded.
