Recycling apparatus and method for door glass of vehicle

The present invention relates to an apparatus and a method for recycling a door glass for a vehicle, and more particularly, to select a coating paper inside a door glass and to present other pretreatment processes to improve the recyclability of a used vehicle glass. A recycling apparatus and method.

In general, windshields and rear glass, front and rear door glass (FRT & RR DOOR GLASS) of scrap cars are heavy parts, and they are relatively heavy parts. Failure to re-use or recycle parts composed of these inorganic materials causes landfilling problems.

Among the glasses, it is considered that the glass is relatively reused or easily recycled, rather than the front / rear door glass rather than the fixed glass such as the windshield and the rear glass.

Because the fixed glass windshield is inserted into the glass between the glass to prevent the collision in the event of collision, the rear glass is difficult to recycle because the hot wire for the purpose of removing the frost is bonded.

On the other hand, the front / rear glass is glass that maintains a fairly clean glass state unless there is any foreign matter, so it is easy to recycle.

In order to dismantle and reuse or recycle the door glass in the abandoned vehicle, the door glass must be kept at the level of genuine parts.

Currently, most of the door glass coming out of the abandoned cars are kept in a state where the coated paper (thinning film) is adhered to, and the color of the door glass is attached to the glass until it is discarded due to aging due to overexposure to direct sunlight. There are many cases.

Even if the door glass is dismantled, it is difficult to reuse or recycle it as it is, so to obtain clean pure glass itself, the coated paper must be peeled off. The stripped glass can then be processed into reusable or other recyclable raw materials.

In the case of the coated paper is usually composed of PET (raw material name: polyethylene terephthalate polyester film) series, harmful gas may be generated during melting into the heating furnace.

In particular, when the waste glass is recycled to foam glass, the melting point of the coated paper is very low compared to the glass, causing a boiling phenomenon when the temperature rises, which causes the formation of homogeneous bubbles in the foam glass. Because of this, glass recycling is a difficult reality.

On the other hand, the door glass must be peeled off again after the disassembly of the tinting film to separate by the material must be separated by removing the adhesive formed between the coated paper and the glass.

In this case, the worker usually removes the coated paper by directly scraping the physical force with a tool using alcohol or the like.

Since the process of separating the film is complicated and the parts must be dismantled by human power, it takes too much work time and increases the recovery cost. There are many threats to worker safety in the handling of drugs.

In order to solve this problem, the proposed Patent Publication No. 2005-0019392 discloses a door glass tinting film peeling system of a scrapped vehicle that removes coated paper by recovering a circular shape of the door glass without breaking the entire glass.

However, at present, the domestic junkyard does not collect the original door glass without dismantling the vehicle fastening element and breaking the entire glass, but instead of dismantling tools to facilitate storage and shorten the dismantling time. It is often used to break and recover the glass.

In this case, it is impossible to remove the coated paper attached to the door glass by using the proposed patent technology.

In addition, in order to effectively recycle the door glass, it is impossible to apply it to general recycling materials such as glass flakes and other recycling materials unless the black paste part printed on the door glass is removed. Recycling of glass fiber, which is a recycling material, limits the recycling method of door glass.

The present invention has been made in view of the above, it is selected by the wind paper using the windshield door glass including the black paste and fine glass, and the transparent door glass and black paste from the door glass selected by the color sorting device By separating the printed door glass, the transparent door glass is recyclable, the black paste printed door glass can be recycled as a landfill or glass fiber material, and the sieve vibrating device separates the fine glass from the coated paper. , Coated paper can be used for incineration / heat recovery / recycling of materials, and fine glass can be recycled with raw materials such as foamed glass, providing recycling apparatus and method for automobile door glass to improve the recyclability of waste door glass.

4. Coated paper is removed from door glass to prevent harmful gas and pollution of working environment when melting coated paper for glass recycling.

5. Since the recycling of waste glass with a large gross weight ratio is essential to satisfy domestic and overseas scrap regulations, we can actively respond to this.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The recycling method of door glass is as follows.

1. Door glass recovery

When a junk car is loaded into the junkyard, the door glass recovery device is used to recover the door glass.

The recovery method is as follows.

1) Open the door of the vehicle and insert the door into the inlet of the glass recovery device.

2) Insert the device to the end and hold the nonwoven fabric in the inlet part.

3) Break the glass with a crushed hammer. The crushed glass is collected by falling into the lower glass collection container.

4) At this time, tap the glass using the back of the hammer.

5) When the glass is collected, take out the recovery device and recover the glass.

When the dismantling operation that maintains the original shape of the door glass and the workability using the door glass recovery device are compared, the following table 1 shows.

As shown in Table 1, due to the cost problem caused by the difference in recovery time (dismantling time) and work intensity, recovery is often performed by breaking the door glass.

2. Door glass (coated paper)

When recovering the door glass to which the coated paper is attached by using the glass recovery device, the coated paper catches the cracked glass in the shape of the recovered glass shown in FIG. 1 like the PVB film of the front glass, and thus requires additional crushing. .

3. Shredding

As shown in Fig. 2, the door glass is crushed using a low speed grinder or the like.

More specifically, in the case of the door glass recovered from the junkyard, the adhesive strength between the coated paper and the front of the door glass is weakened due to aging (average 6-7 years from the time the vehicle is shipped out). The door glass is tempered glass. When glass is applied to the outside, the glass is broken to a certain size.

In addition, when shredding using a low speed grinding machine, the door glass has a small contact surface with the coated paper and the bonding force between the door glass and the coated paper is weak, so that after the grinding, the coated paper and the door glass shredded material are separated from each other.

In fact, when crushing the glass recovered from the junkyard using a low speed crusher as shown in Figure 3 coated paper and broken door glass shows a apart from each other.

4. Wind power sorting device

The door glass is introduced into the wind power selection device 22 by the vibration device.

Since the apparent density of glass and coated paper, that is, the difference in mass to volume, is large, the sorting method using a windscreen is effective.

In the case of different materials, the zigzag windscreening device has the advantage of simple structure, but if water is absorbed by the screening object, it is likely to be accumulated in the device. There is a difficulty.

In addition, in the case of cyclone-type windscreening device, the space and installation cost are high to screen door glass and coated paper which have a large specific gravity difference.

4 is a conceptual diagram illustrating a windscreen selection device according to an embodiment of the present invention.

As shown in FIG. 4, the present invention prevents a phenomenon in which glass having a high specific gravity when the crushed glass is directly injected into the windscreen device 22 is coated with the free paper from the windscreen device. It provides a vibrator type inlet 10 for.

The vibration type inlet 10 is to increase the sorting efficiency by helping the door glass and the coated paper to be scattered well by the vibration when input to the windscreen.

In order to transmit the left and right vibrations to the vibrating inlet 10, the motor unit 11 is installed at a lower portion of the vibrating inlet through a spring.

Here, the method for transmitting the left and right vibration to the vibrating inlet 10 by the motor unit 11 may be adopted without particular limitation as long as it is a method commonly known in the art.

An apparatus support 14 for supporting the apparatus such as the motor unit 11, the air fan 12, the air outlet 13, and the like is provided.

In addition, the lower portion of the vibrating inlet 10 is provided with an air fan 12 for providing wind power to separate the door glass and the coated paper.

The most important factors for screening dissimilar materials in wind screening are wind power, ie wind speed and wind volume.

Publication No. 2003-0051482 proposed to derive wind power optimized for screening efficiency between door glass and coated paper is based on the end-products generated after recovering various recyclable materials for each of the manpower ships. By using a muffler for automatically sorting vinyl, paper, plastic containers, and glass by type, an induction screen, and a circular rotary conveyor, there is disclosed an end-of-life wind sorting device.

Experimental results using the windscreening device is as follows.

As shown in FIG. 5, the windscreen sorting device 100 is a windscreen sorting device for sorting plastic end products rather than sorting different materials such as door glass and coated paper as in the present invention. Consists of dogs.

Outlet 1 (existing before entering the sorting section) among the outlets is a section for removing heavy soils such as stones and sand from waste plastic end products, not the outlets of the material sorted by wind, and free of material smaller than the screen. It is a section that falls. The location ⓐ shown in the drawing section is less influenced by the main wind.

At this time, the wind rises between the screens to remove the actual heavy sand and dust, but the strength is small compared to the main wind.

In the case of the sorted materials 2, 3, and 4 discharged from the outlets 2, 3 and 4, respectively, the section is directly selected by the influence of the main wind power of the apparatus.

Among these three outlets, the optimum sorting air volume of glass and coated paper can be derived through the sorting properties (selection purity) of sort 2, the weight and sorting properties of sorts 3 and 4.

Referring to the results of the experiment using the above proposed device is shown in Table 2 below.

In the above results, the weight and screening properties of sorts 2, 3, and 4 are shown, the content of coated paper in the glass corresponding to sort 2 increases when the wind speed is 5 m / s or less than 200 m 3 / h. In the case of the coated paper corresponding to, 4, the amount of screening was very small, and the glass content ratio increased in the coated paper at the wind speed of 7.5m / s and the air flow rate of 350㎥ / h or more.

According to the result of analyzing the weight of the sorted product and the sorting properties of the sorted product, when the windshield is used to sort the door glass and coated paper, the wind power generated by the air fan and applied to the coated paper and the crushed door glass has a wind speed of 5 to 7.5. It should be set to m / s and air volume 200 ~ 350 ㎥ / h.

At this time, the experimental data in Table 2 was obtained based on the weight, and even if the amount of glass slightly increased in the selection 3 showed a sharp increase in weight, weight ratio data and selection efficiency of each selection (selection) The optimal wind power was derived by checking the water properties.

An air nozzle 16 is formed in the air fan 12 to discharge air generated in the fan to the sorting chamber 15, and sorts the door glass and the coated paper by wind power generated by the air fan 12. A constant volume sorting chamber 15 is formed therein.

The dotted line shown in FIG. 4 is an expected movement path of air.

An air outlet 13 is formed at the upper end of the wind power sorting device so that the air generated from the air fan 12 is discharged out of the device.

The sorting chamber 15 has a door glass outlet 17 through which a large weight of the door glass that is not blown by the wind (not selected) is discharged to the front of the air fan 12, and coated paper sorted by the wind is discharged. The coated paper outlet 18 is partitioned.

Between the door glass outlet 17 and the coated paper outlet 18 is divided into the door glass and the coated paper to be sorted by the wind, the sorting partition plate 19 for preventing the mixing of the door glass and the coated paper by the swirl flow in the vertical direction It is installed.

One side wall surface of the coated paper outlet 18, which is the end of the sorting chamber 15, is provided with an adsorption preventing screen 20 that prevents the sorted material from being adsorbed to the air outlet 13.

Referring to the operating state of the windscreen selection device according to an embodiment of the present invention by such a configuration as follows.

First, when the door glass containing the coated paper is introduced through the vibrating inlet 10, the door glass is dropped to the door glass outlet 17 by the wind power generated from the air fan 12, the coated paper outlet 18 To fall).

In addition, the air introduced into the sorting chamber 15 is discharged to the air discharge port 13, at this time the wind power generated by the air nozzle by the air fan 12 to the wind speed of 5 ~ 7.5m / s and air volume 200 ~ 350 ㎥ / Adjust to h

5. Sorting Glass + Black Paste

The door glass sorted by the wind power sorting device includes glass painted with black paste, and coated paper including fine glass is sorted together.

6. Color selection

In the case of door glass, there exists a black paste part for describing a manufacturer's mark etc.

If the black paste portion remains in the sorted glass, it becomes difficult to recycle the glass.

Currently, in the case of glass in which the black paste part is present in the glass manufacturing process, it is not recycled by waste glass, such as general waste glass, but is recycled entirely by glass fiber, which is a low-grade recycled material.

Therefore, it is necessary to remove the black paste from the door glass. The most obvious difference between the selected door glass and the black paste area is the color. Color screening is used to remove black paste from the door glass.

Using an X-ray scanner using illumination (previous commercialization equipment), when the black paste of black color comes into the scanner, the air blower operates to sort.

6 is a conceptual diagram illustrating the configuration of a color screening apparatus using an X-ray scanner.

As shown in FIG. 6, when the door glass is introduced into the color sorting device 23 through the conveyor 21, when the black paste of the input glass is printed, the detector 24 (X-ray scanner) receives it. Recognizing, the air blower 25 is operated to spray the air to remove the portion of the door glass printed with black paste.

The color sorting device is currently commercialized in recycling glass sorting operation.

Reference numeral 26 is an air fan.

9. Fine glass + coated paper

When screening the door glass and the coated paper using the wind power sorting device 22, most of the glass and coated paper is screened, but contains a very small amount of fine glass (1 mm or less) generated during crushing.

The coated paper contained in the particulate glass must be removed to increase the recycling width of the coated paper, and the recovered particulate glass can be used as recycled glass such as foam glass.

7 is an image showing the particulate glass + coated paper sorting.

10. Vibration Screening

8 is an image showing the appearance of a general body vibration screening device, Figure 9 is a conceptual diagram for explaining the operation principle of the body vibration screening device in FIG.

In the coated paper containing fine glass, the particles of the coated paper are mostly 10 mm or more, while the fine glass shows a particle distribution of 1 mm or less (average 500 μm or less). Screening is performed using a body vibration screening device 28 having a mesh spacing of 1 mm or less.

In this case, as shown in FIG. 9, a mesh body 27 having holes having a diameter of 1 mm or less is used to efficiently sort the coated paper and the fine glass. The mesh body 27 vibrates with a slight inclination so that the coated paper and the fine glass can be advanced by vibrating. Particularly, in the case of the fine glass, since the amount of generation is small and the weight is light, a sharp inclination in the apparatus is shown in FIG. 9. It is efficient to have
