[0013]

Embodiments of the present invention will be described below with reference to the drawings.

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 components are separated into cathode ray tube 4, deflection yoke 5, and covered wire 6. The weight ratio of each part is 5 for CRT 4
The largest part is 2.2% and other parts are separately shredded at 47.8%, from which 14% can be recovered as ferrous and non-ferrous.

The cathode ray tube 4 is placed on a conveyor 7 with its front face down, and an electron gun 8 at the rear end of the projection is cut off at an electron gun cutting section 9 mainly composed of a glass cutter. Next, in order to prevent implosion, the explosion-proof band 10 around which the maximum outer peripheral portion of the cathode ray tube 4 is fastened is cut by a rotary grindstone or rotary saw-shaped explosion-proof band cutting section 11. When the explosion-proof band 10 is removed,
Since the reinforcing tape 12 is wound and adhered as a cushioning material in order to prevent the glass surface from being damaged by the explosion-proof band 10, it is completely peeled off by the reinforcing cushioning material removing portion 13 using a rotating brush.
Further, since an adhesive label or the like for displaying components is attached to the rear surface of the cathode ray tube 4, it must be removed in the same manner.

Although the adhered material on the surface of the CRT 4 has been removed, the purpose of this apparatus is to recover pure glass resources, and the CRT 4 has a panel glass 14 on the front side and a CRT on the back side. Since the funnel glass 15 has different components, it is necessary to divide the components. Then, the CRT 4 is mounted on the CRT dividing device 16. The CRT splitting 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 CRT 4, and cuts the outer periphery of the CRT 4 at the determined position. . A hot wire such as a nichrome wire is wound around the cut and heated, the temperature inside the cathode ray tube 4 is raised to about 200 ° C. Cracks along the cut made earlier by the stress caused by At this time, an appropriate impact should be applied to the outer periphery.

The cutting position is a position within 10 mm from the seal edge toward the panel. When 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 cut at the mold match line (MML) is 70%.
When about 30% of the weight of the panel glass is mixed into the funnel glass 15 side, the weight of the panel glass 14 is 1.79 times as large as the weight of the funnel glass 15, so that the composition of the funnel glass 15 is 54%. Different materials are mixed.

Therefore, the specific gravity and the concentration of the funnel glass 15 are hindered. Therefore, in this facility,
The cutting position was set within a range of 10 mm or less from the seal edge.

The divided funnel glass 15 is sent to a blasting device 19 by a conveyor 18, the shadow mask 17 mounted therein is removed, and the panel glass 14 is sent to a phosphor removing device 21 by a conveyor 20.

In the television, an organic substance called a dug is applied to the inner and outer surfaces of the funnel glass 15 in order to stabilize an image. Types of dugs include Aqua Dug (black), Titanium Dug (gray), Bengala Dug (red)
However, when these organic substances are mixed into the cullet, they become impurities in the glass melting furnace and precipitate metallic lead. Therefore, the dug must be completely removed at this stage. The blasting device 19 can perform dry and continuous treatment. The upper and lower four nozzles 22 are swung to remove the applied tag. Glass powder is used as the projection material to prevent impurities other than glass from being mixed into the cullet.
The projected glass powder and the removed dug are separated by the cyclone 23, the glass powder that can be reused is collected, and the unusable powder is collected by the dust collector 24.
Dust is collected.

The panel glass 14 sent to the phosphor removing device 21 removes the phosphor applied to the inner surface of the panel glass 14 and the deposited aluminum film by a rotating brush 25 having a suction nozzle, and uses a sinter ceramic filter. The dust is collected by the dust collecting unit 26.

The panel glass 14 and the funnel glass 15 from which the coating material has been removed in the steps so far are sent to crushing devices 27 and 28, respectively, and crushed into cullet. There is no particular difference between the two crushing devices.

The crushing equipment includes a double roll crusher, a jaw crusher, and the like. The crushing apparatus 27.2 is used based on comparison of problems such as cullet particle size, noise, and vibration.
8 adopted a double roll crusher. This is a two-shaft double roll crusher, and three axles each have a total of six roll tires. The material is a cemented carbide containing chromium or the like, and the clearance is 15 mm for both panel and funnel systems.

The particle size of the cullet can be made uniform to 10 mm to 50 mm, the noise can be reduced to 80 dB or less, and the vibration can be reduced to 2 μm or less. Further, in order to collect glass dust generated at the time of crushing, a crushing and dust collecting device 34 using a bag filter is provided.

Panel glass 14 and funnel glass 1
5 are provided with metal pins for fixing the shadow mask 17 and as a cathode, respectively. 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 subjected to a magnetic separation device 29/30 to sort metals to make a cullet composed entirely of glass.

Glass dust sucked from suction nozzles 32 and 33 provided at important points of the crushing devices 27 and 28 by the crushing and dust collecting device 31 is separated based on a prescribed standard, and is reused as a blasting material by the blasting device 19. Things.

Reference numerals 34, 35, 36, and 37 denote conveyors for transferring the panel glass 14 and the funnel glass 15 to each device.
