Description

  The present invention relates to a method for recycling automobile waste glass, and more particularly, to a method for recycling automobile waste glass to obtain a reusable cullet using automobile glass made of tempered glass such as rear glass and side glass as a plate glass raw material.

  Conventionally, most of waste glass for automobiles has been treated as shredder dust without being separately collected from other automobile parts (plastics and metals).

  In addition, the presence of various surface deposits (masking, silver prints, etc.) on waste glass for automobiles is a cause of difficulty in recycling. For example, when a glass cullet with masking attached is used as a raw material for plate glass production, there is a problem that the masking is not completely melted and remains as a defect in the produced plate glass. When glass cullet with silver print attached is used as a raw material for plate glass production, there is a problem that the silver contained in the silver print erodes the refractory bricks of the melting kiln used for plate glass production and shortens the life of the kiln. Because.

  Under such circumstances, a bill on recycling for automobiles was passed in July 2002, and full enforcement from January 2005 was decided. In this bill, waste glass for automobiles is contained in shredder dust and is to be processed, but there is also a movement to collect and recycle the glass. In recent years, a method for recycling waste glass for automobiles has been sought. ing.

  Among the waste glass for automobiles, especially the rear glass and side glass of automobiles are tempered glass, and therefore have the property of being scattered as small pieces when broken. Therefore, it is impossible to cut and remove only the portion where the masking of the rear glass or the side glass or the silver print is adhered. Furthermore, if the glass is not flat and does not have the same shape, such as glass that has been tempered and bent, deposits cannot be uniformly removed by using means such as a grindstone or sandpaper.

  As a method for recycling such glass, a method is conceivable in which, after the plate-like glass is crushed to form a cullet, only the cullet-shaped glass having no color or deposit is separated and collected. However, since the cullet-shaped glass that does not have color or deposits cannot be completely separated, there is a problem that the collected cullet or the cullet with impurities adhered to the collected cullet. is there. In addition, the removed cullet is in a state where a considerable amount of cullet to be collected is mixed, but the removed cullet is mainly a cullet with impurities attached, so it is not reused as waste. Since it is processed, there is also a problem that the reuse rate of the entire cullet is poor. Further, even if the above-described apparatus is used, the silver print used for the heat ray of the glass for automobiles is linear and very thin, so that there is a problem that the cullet with the silver print cannot be separated.

In order to eliminate the problems caused by the above recycling method, the deposits may be removed in advance and then collected in cullet form. As a method for removing deposits from glass, a first conventional example using a chemical treatment (for example, see Patent Document 1), a second conventional example using a grindstone, sandpaper, or the like (for example, see Patent Document 2), a sandblasting device A third conventional example using the above (for example, see Patent Documents 2 and 3) is known.

  However, in the first conventional example, masking and silver print can be removed by treatment with acid, but such chemical treatment has a problem that a complicated apparatus is required for treatment of waste liquid after treatment.

  Further, in the second conventional example, there is a problem that, when applied to glass having a relatively large area such as automobile glass, which is curved and has the same shape, impurities cannot be peeled uniformly.

  Furthermore, if it is reused as a raw material for the production of flat glass using a float kiln or the like with different types of glass mixed in, it may cause problems in the color and light transmission characteristics of the flat glass product. When glass of various varieties is mixed, as in the third conventional example, it is not enough to recycle simply by removing impurities on the glass, and it is necessary to sort the glass by type. There is a problem that there is.

When the waste glass for automobiles is separated based on the determined varieties, and the separated waste glass for automobiles is crushed into a cullet shape, when the waste glass for automobiles is collected as cullet, It has been found that the reuse rate of waste glass for automobiles can be improved by preventing mixing and ensuring the separation of each glass type.

  The present invention has been made based on the above findings.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a flowchart of a recycling process for waste glass for automobiles according to an embodiment of the present invention.

  In FIG. 1, first, the glass part of the scraped automobile is removed and recovered as a scrap glass for a car in the form of a plate (step S101), and the type of the collected scrap glass for a car is determined (step S102). The determination in step S102 is performed by measuring the color of the collected automobile waste glass and the transmittance of light of a specific wavelength with a color sensor. In addition, by collecting the waste glass for automobiles in the form of a plate and measuring the product type, the color of the waste glass for automobiles and the transmission of light of a specific wavelength can be reliably compared with the conventional cullet-shaped separation means. Measurements such as rate can be made.

  Furthermore, if the glass to be measured in step S102 is limited to several types of glass that are produced in a relatively large amount, the reuse rate can be improved with less investment.

  The sensor used for the measurement in step S102 can measure the color and brightness of glass at the same time. For example, the color and brightness of glass of each type are stored in advance, and the stored color and brightness It is possible to use a color sensor that makes it possible to discriminate between glass types by digitizing the degree of coincidence between the measured values and setting a threshold value for the degree of coincidence.

  Further, if this color sensor is arranged in the number of glass types to be sorted, the glass of each type can be identified efficiently.

  The sensor that can be used in the present embodiment discriminates the glass type by the degree of color and brightness, but is not limited to this. For example, discrimination by color alone, discrimination by brightness alone, spectral The determination may be made by measuring the transmission characteristics, or the glass with a conductive film may be determined by measuring the electric resistance of the film or using a metal sensor.

  Moreover, as the sensor according to the present embodiment, it is desirable to use a commercially available sensor. This makes it possible to create a system with relatively little investment.

  Next, the deposits (masking, silver print, etc.) on the automobile waste glass collected in step S101 are removed (step S103).

  It is desirable to use a sandblasting apparatus as the apparatus that performs the process of step S103. This is because it is the simplest apparatus among those generally known as an apparatus that scrapes off deposits on the surface by spraying an abrasive onto the glass surface and is relatively inexpensive. Moreover, even if the glass is not flat and has a shape that is not the same, such as tempered glass, the deposits can be uniformly removed by using such an apparatus.

  As shown in FIG. 2, the sandblasting apparatus 200 includes a compressor 201 that supplies air, an abrasive hopper 202 that contains an abrasive, an abrasive that is supplied from the abrasive hopper 202, and an air that is supplied from the compressor 201. A mixing unit 203 to be mixed, and a nozzle 204 for injecting abrasive and air from the mixing unit 203 onto the automobile waste glass 205 are provided. Further, the abrasive in the abrasive hopper 202 flows under the negative pressure of the mixing unit 203.

  Further, the air supply source may be a blower instead of the compressor 201, or air may be used, the abrasive may be accelerated by rotating blades, and the ejection medium may be a gas other than air.

  The apparatus for removing deposits is not limited to the sand blast apparatus 200 as long as it is an apparatus for spraying and polishing an abrasive on the glass surface, and the following apparatuses may be used. Hereinafter, characteristics of each device shown in Table 2 will be described.

1) Shot blasting equipment (using iron particles)
Although mechanically the same as the sandblasting apparatus 200, it is an apparatus that uses iron particles as an abrasive.

  Thereby, the abrasive can be separated from the polishing scraps after polishing by an easy means such as a magnet, and the amount of waste can be reduced. However, since the abrasive is heavy, in some cases, means such as a bucket elevator may be necessary in the middle of the abrasive conveyance mechanism.

2) Liquid honing device In liquid honing, a polishing liquid composed of an abrasive and a liquid is transported to a mixing unit 203 by a pump and mixed with air supplied from a compressor 201, and the polishing liquid is directed toward an automobile waste glass 205. It is a device to be injected.

  Since the abrasive is sprayed together with the liquid, there is little generation of dust and the working environment can be kept good.

3) Water Jet Device The water jet device is a device that injects, as a water jet, a polishing liquid obtained by mixing an abrasive with water fed from a high-pressure pump instead of the compressor 201 at the mixing unit 203.

  Since the abrasive is sprayed together with the liquid, there is little generation of dust and the working environment can be kept good. At this time, the liquid may be other than water.

  The apparatus including the sandblasting apparatus is used for the process of step S103, whereby the surface of the automobile waste glass is slightly shaved, but deposits on the automobile waste glass can be reliably removed.

  In addition, in view of the processing speed, it is desirable that these methods be an automated apparatus with a plurality of nozzles, but human processing such as having a nozzle is also possible.

  Returning to FIG. 1, next, the waste glass for automobiles from which deposits have been removed in step S103 is sorted based on the type determined in step S102 (step S104).

  This classification method may be one in which classification is performed manually based on the information on the type confirmed, and the information on the type confirmed in step S102 is transmitted to the sorting apparatus that performs the processing in step S104 via a computer or the like. It may be automated.

  Alternatively, semi-automation may be performed by using a separation method between the above two methods, that is, a separation method in which a person switches by a switch based on information on the type confirmed.

  Thereafter, each glass sorted in step S104 is crushed into a cullet shape (step S105), and this processing is finished as a raw material in a plate glass manufacturing process such as a float kiln.

  In this crushing method, separately collected and collected plate-like glass may be stocked for each product type, and may be crushed together after being collected to some extent, or crushed every time it is sorted, Stock for each type may be used. In addition, although crushing is desirably automated, it may be performed manually.

  In the above recycling method, it is desirable to automate the steps S103 to S105. As a result, the entire system can be labor-saving.

  In the present embodiment, the product type determination process in step S102 is set before the impurity removal process in step S103, but can also be set after. However, in this case, since the glass is ground in the impurity removal step and is not transparent, a discrimination method using transmitted light is not applicable.

  Furthermore, it is desirable that the recycling process according to the present embodiment is performed on the rear glass and the side glass, among waste glass for automobiles, but the present invention is not limited to this, and examples thereof include a windshield and a moon roof. The present invention may be applied to other glass.

  Furthermore, the recycling treatment according to the present embodiment may be applied not only to the waste glass for automobiles but also to the recycling of glass having impurities on its surface, such as glass for construction and glass for electronic materials.

  Further, the recycling process according to the present embodiment may be applied when removing impurities from a metal plate or a ceramic plate to which impurities are attached, in addition to glass.

  Next, examples of the present invention will be described.

  First, five types of glass for separation test were used: Green glass, UV Green glass (Green glass that absorbs ultraviolet rays), dark glass domestic products, dark glass overseas products, and dark glass with a reflective film. These are currently being produced in large numbers.

  The color of the glass and the degree of light and darkness were measured with a commercially available color sensor, and the degree of coincidence between the color of the glass of each kind stored in the sensor and the degree of light and dark was measured. Table 1 shows the measurement results.

  In the results of Table 1, “◯” indicates a case where the degree of coincidence of measured values is within the threshold value, and “X” indicates a case where the measured value is outside the threshold value.

  From the above results, it was found that the glass could be easily separated by the color sensor.

  Next, the deposit removal test glass was produced by the following method.

  A paste-like masking was applied to almost the entire surface of one side of a glass plate having a thickness of about 3 mm, and a paste-like silver print was applied to the center of the glass within a range of about 40 mm × 40 mm. Most of the masking components are glass frit. The silver print is mostly silver, but a small amount of glass frit is mixed. The glass coated with masking and silver print is tempered by air cooling through a tempering process. At the same time, the glass frit in the masking and silver print melts and adheres firmly to the glass.

  About the above-mentioned test glass, under the conditions of Table 2, deposit removal results when using a sandblasting device (Table 3), results when using a shot blasting device (Table 4), and a liquid honing device were used. The case results (Table 5) and the results using the water jet device (Table 6) are shown.

From the above results, it was found that the following ranges are suitable as the processing conditions.
(1) Sand blasting apparatus, shot blasting apparatus, liquid honing apparatus When using these apparatuses, it was found that the hardness of the abrasive must be of the order of alumina, iron particles, or the like. This is because if the abrasive is low in hardness, for example, glass particles cannot remove deposits, and conversely, if the hardness is high, the wear of the nozzle and the like becomes severe, and the frequency of nozzle replacement becomes excessive.

  It was found that the count of the abrasive used in each of the above devices needs to be # 40 to # 200. If the abrasive grain size is too coarse, the amount of scraping of the glass increases, and the possibility of glass breakage increases. Conversely, if the abrasive grain size is too fine, the scraping amount decreases, resulting in a longer processing time or a This is because problems such as inability to remove the kimono arise.

It has been found that the spray pressure of the abrasive or polishing liquid from the nozzles in each of the above devices needs to be 0.4 MPa to 0.6 MPa. This is because if the spray pressure is too high, the glass tends to break, and if it is too low, the deposits cannot be removed.
(2) Water Jet Device When using a water jet device, it was found that the type of abrasive is garnet. This is because garnet is a general abrasive used in water jet devices, and the hardness of garnet is comparable to that of alumina and iron particles.

  It was found that the count of the abrasive used in the water jet apparatus needs to be # 100 to # 180. If the abrasive grain size is too coarse, the amount of scraping of the glass increases, and the possibility of glass breakage increases. Conversely, if the abrasive grain size is too fine, the scraping amount decreases, resulting in a longer processing time or a This is because problems such as inability to remove the kimono arise. It was also found that the deposits could not be removed without the abrasive.

  It has been found that the spray pressure of the polishing liquid from the nozzle in the water jet apparatus needs to be 30 to 35 MPa. This is because if the spray pressure is too high, the glass tends to break, and if it is too low, it cannot be removed.

It is a flowchart of the recycling process of the waste glass for motor vehicles based on embodiment of this invention. It is the schematic of the sandblasting apparatus which concerns on embodiment of this invention.
