[0011]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0012]
As shown in FIGS. 1 to 3, the waste TV receiver 1 processed by this apparatus is sequentially disassembled from the outside as it flows on the conveyor 2, and the cabinet substrate 3, the cathode ray tube 4, the deflection yoke 5, and the covered wire 6. The parts are separated. The weight ratio of each part is the largest at 52.2% for the CRT 4, and 47.8% for the other parts, and 14% can be recovered as iron / non-iron content from that.
[0013]
The cathode ray tube 4 is placed on the conveyor 7 with its front face down, and the electron gun 8 which is the rear end of the projection is cut off by an electron gun cutting part 9 mainly composed of a glass cutter. Next, in order to prevent implosion, the explosion-proof band 10 wound around the maximum outer peripheral portion of the cathode ray tube 4 is cut by a rotary grindstone or a rotary saw-shaped explosion-proof band cutting part 11. When the explosion-proof band 10 is removed, a reinforcing tape 12 is wound around and bonded to the surface of the CRT 4 as a cushioning material so as to prevent the explosion-proof band 10 from scratching the glass surface. The removal unit 13 completely peels off. Further, an adhesive label or the like for displaying parts is attached to the back surface of the cathode ray tube 4 and must be removed in the same manner.
[0014]
Although the sticking material on the surface of the cathode ray tube 4 has been removed, the purpose of this apparatus is to collect pure glass resources. The cathode ray tube 4 has a front panel glass 14 and a rear surface funnel glass 15. Since the components are different, it is necessary to divide them. Then, the cathode ray tube 4 is placed on the cathode ray tube dividing device 16. The cathode ray tube dividing device 16 has a cutter positioning portion (not shown) for applying a glass cutter to the boundary between the panel glass 14 and the funnel glass 15 of the cathode ray tube 4, and cuts the outer periphery of the cathode ray tube 4 at the determined position. . A hot wire such as a nichrome wire is wound and heated along the cut line, the temperature inside the cathode ray tube 4 is raised to about 200 ° C., the heat wire is separated, and the position is cooled with a water-containing sponge-like substance. It breaks along the cuts made earlier due to the stress caused by. At this time, an appropriate impact may be applied to the outer periphery.
[0015]
The cutting position is within 10 mm from the seal edge to the panel side. When it is cut at that position, the remaining weight of the panel glass 14 is 95%, which is good, but the remaining weight of the panel glass 14 when it is cut by the mold match line (MML) is 70%. When about 30% of the panel glass weight is mixed with the funnel glass 15, the weight of the panel glass 14 is 1.79 times larger than the weight of the funnel glass 15, so that the composition of 54% is contained in the funnel glass 15. Different materials will be mixed.
[0016]
Therefore, the specific gravity and density adjustment of the funnel glass 15 are hindered. Therefore, in this equipment, the cutting position is within a range of 10 mm from the seal edge.
[0017]
The divided funnel glass 15 is removed to the blasting device 19 by the conveyor 18, the shadow mask 17 mounted therein is removed, and the panel glass 14 is sent to the phosphor removing device 21 by the conveyor 20.
[0018]
In order to stabilize an image on the television, an organic substance called “dug” is applied to the inner and outer surfaces of the funnel glass 15. There are various types of doggs, such as aqua-dag (black), titanium-dag (gray), and bengara-dag (red). When these organic substances are mixed into the cullet, they become impurities in the glass melting furnace, and lead metal Will be deposited. Therefore, the doug must be completely removed at this stage. The blasting device 19 can perform a dry process continuously. A total of eight nozzles 22 in the upper and lower directions are swung to remove the applied doug. Glass powder is used for the projection material to prevent impurities other than glass from entering the cullet. The projected glass powder and the removed Doug are separated by the cyclone 23, the glass powder that can be used again is collected, and the unusable powder is collected in the dust collector 24.
[0019]
The panel glass 14 sent to the phosphor removing device 21 removes the phosphor coated on the inner surface of the panel glass 14 and the deposited aluminum film with a rotating brush 25 having a suction nozzle, and collects dust using a sinter ceramic filter. Part 26 collects the dust.
[0020]
The panel glass 14 and the funnel glass 15 from which the coating material has been excluded in the steps so far are respectively sent to the crushing devices 27 and 28 and crushed to form cullet. There is no particular difference between the two crushing devices.
[0021]
The crushing equipment includes a double roll crusher, a jaw crusher, and the like, but the crushing devices 27 and 28 employ a double roll crusher from a comparison of problems such as cullet particle size, noise and vibration. It is a biaxial double roll crusher, and 6 roll tires, 3 in total, are attached to one axis. The material is a cemented carbide containing chromium and the clearance is 15 mm for both panel and funnel systems.
[0022]
The particle size of the cullet can be made uniform between 10 mm and 50 mm, the noise can be reduced to 80 dB or less, and the vibration can be reduced to 2 μm or less. Moreover, in order to collect the glass dust which generate | occur | produces at the time of crushing, the crushing dust collector 34 which uses a bag filter is provided.
[0023]
The panel glass 14 and the funnel glass 15, respectively, for fixing the shadow mask 17, a metal pin is only attached as negative electrode. Since metals cannot be put into the glass melting furnace, the panel glass 14 and the funnel glass 15 must be crushed to remove the metals. For this reason, the crushed cullet is sorted through the magnetic separators 29 and 30 to sort the metals into a cullet made entirely of glass.
[0024]
The glass dust sucked from the suction nozzles 32 and 33 provided at the essential points of the crushing devices 27 and 28 by the crushing dust collecting device 31 is separated based on a prescribed standard and reused as a projection material by the blast device 19. .
[0025]
Reference numerals 34, 35, 36, and 37 denote conveyors for transferring the panel glass 14 and the funnel glass 15 to each device.
[0026]
【The invention's effect】
As described above, according to the present invention, glass materials composed of different types are separated efficiently and with high purity by means for sequentially removing incidental parts and deposits of cathode ray tubes of television receivers that are waste home appliances. By using the material dust generated in the process in the process, it is possible to provide a CRT regeneration pretreatment system for a television receiver which has an effect of increasing the degree of reuse.
