Abstract

A method for recycling glass from a face panel of a liquid crystal display (LCD) is used to recycle glass from a face panel of a waste LCD and comprises: (a) removing glass from a face panel of a waste LCD and grinding the glass into a glass powder; (b) vaporizing the liquid crystal adhered on the glass powder at high temperature and removing the liquid crystal vapor with hot wind, in which the flow path of the hot wind is opposite to the flow path of the glass powder; burning the liquid crystal vapor at an even higher temperature into carbon dioxide and water in order to separate the liquid crystal and the glass powder and obtain a glass material; and (c) collecting the obtained glass material for recycling.

Traditional displays are often too large in color, which is inconvenient for computers. It is also not in line with the mainstream of crystal displays to widely replace the traditional device market. However, as mentioned above, most of the liquid crystal displays that are relatively discarded nowadays do not propose an effective recycling sound. Therefore, in order to solve this problem, the present invention researches intensively and cooperates with scientific effects to improve the above-mentioned shortcomings. The recovery method of the main purpose of the present invention is developed. After the main recovery is performed, the recovery method for the liquid crystal display to the environment is completed. This display has been improved by Fang et al. On the display surface of the liquid crystal display. In the brain industry, the image tube is used to carry electricity. It is easy to carry a color projector. The surface plate is broken. The special image tube of the brain's pendulum, Panpo Lili's recovery has become comparable, and it is an innovation, which is designed by the same nature, so it is collected for the current recovery method to facilitate the method. When the general technology is used, its peripheral configuration is particularly significant. For this type of display, notebook computers are now used to display liquid crystal displays. Although liquid crystal displays are widely used by the general public, the number of devices has also increased, and these are sent to landfills or Let it be abandoned, so if the law is repeated, it will inevitably have a negative impact on the environment. Feeling that the above-mentioned shortcomings can be improved, it is for special use. Finally, a reasonable design is proposed. There is a way to provide a liquid crystal display to put Jiang on the screen, and to discard the discarded liquid crystal display for other uses. It helps to solve the problems of the negative effect of the face plate, etc. It is absolutely necessary to discard the waste. The present invention provides a liquid step as follows:

Refer to the step on the crystal display a) First grinding into b) Hot air belt diameter is opposite to water. First, the waste is ground into After attaching the glass powder with the hot air with the glass powder and separating it from the glass powder, the reviewer will refer to the following information for reference. The liquid crystal display glass powder adheres to the liquid crystal vapor path and the liquid crystal is separated, so that the glass can be further advanced. With regard to this description, the face glass on the indicator is removed, and the liquid crystal on the soil powder is evaporated into a liquid crystal in a vapor state. The hot air is reversed, and then carbon dioxide and water are burned at a higher temperature, so that the liquid obtains the glass raw material. Gather and recycle. '^ Step by step to understand the characteristics of the present invention and the detailed description and drawings, but' is not intended to add a picture to the present invention, but is a flowchart of the present invention. The present invention provides a method for recovering disc glass, which is mainly used to recover discarded disc glass for further use in the future. The steps are as follows: first, discard the liquid crystal display glass powder; The liquid crystal on the powder evaporates into liquid crystal in the state of steam lice, wherein the hot air is doubled with the glass powder, which then burns the liquid crystal in the vapor state at a higher temperature to separate the liquid crystal from the glass powder to obtain the glass raw material. After removing the face glass, the glass raw materials obtained by m are collected and recovered. ——What's not is the application of the present invention to the continuous reading processing department 2 1 --------- c Page 5 1226315 Month Modification-E1_91117720 V. Description of the invention (3) Schematic flow chart of the principle; the invention is applied to In actual operation processing, the equipment required roughly includes a coarse crusher 2 0, a hot air evaporation furnace 5 0 1: silo 60 0, and the detailed steps are as follows (please refer to the first figure together) ( a) conveying the face plate glass removed from the discarded liquid crystal display to a coarse crusher 200 by a conveyor belt 10 for coarse crushing and grinding, so that the face plate glass becomes a glass flake with a fine sheet size; (b) At this point, the ground glass powder can first be conveyed into a coarse cylinder 40 by a first conveying mechanism 30, which can be used for glass powder, about 40 0 ° C. Temperature to evaporate the liquid crystal attached to the glass powder into a knife vapor state; the coarse cylinder 40 has an air outlet 41, which can pump the liquid crystal which has been in the vapor state in the coarse cylinder 40 to 80%. 〇It ~ ancient di = slightly) 'In addition, the liquid crystal and glass powder are separated, so that the Γ skin is pumped to (illustration omitted) The liquid crystal will also be burned into harmless carbon dioxide and water due to roasting (ί :) 嗣 Π :: ί temperature; hot air steaming = glass: transported to aforesaid air outlet through a second duct 31 5 2 The two-wind evaporation furnace 50 has an air outlet 51 and the hot air takes off the steam to provide hot air of about one generation, and the powder Γ is broken within 50 to send the wheel to the liquid crystal of the hot-air evaporation furnace. Evaporate, and use Xi__person = filter to make the liquid-sending liquid s remaining in the glass powder powder s wind 瘵 stove 5 0 exhaust port 5 1 similarly pumped. ~ A w-a α cut position ^ exhaust The wind direction of the hot air at the port 51 is to ensure that the glass powder is burning in the person = kiln (not shown), so it is not only the path P 1 and the air outlet g, crystal, and net f state, but also by glass squatting powder Act No. 6 1226315 V. Description of the invention (4) The reverse design of the diameter P 2 can also make clean air enter through the air supply port 5 2 ', that is, the glass powder to be transported to the hot air evaporation furnace 5 0 immediately. The remaining liquid crystals on the glass are separated, and the liquid crystals in a vapor state are pushed toward the air outlet 5 1 to more effectively filter the remaining liquid on the glass powder. Liquid crystal, which can highlight its effect even more in the field of recycling. In addition, the hot air evaporation furnace 50 series is a "forked seal-like sadness" and can make the glass powder more uniform by turning, and it can also be combined. Remove the impurities in the glass powder to purify it; (, C,) Finally, the uniform and pure glass pot 4 is delivered to the storage bin 60 above by a third conveying pipe 32, and at the same time, the storage The silo 6 〇 also ^ the air outlet 6 i can be the last remaining liquid state of the liquid crystal in the vapor state of _ ° c ~ lo〇 (rc of the kiln (illustration omitted) to the vapor state, and r: 2 feet Yao 'maintains the pure state that the glass powder does not contain liquid crystals is big: = raw materials' and prepares it for further reuse by grinding it into fine powder and grinding it into powder.
