Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know. Wherein like reference numerals refer to like elements throughout.

The glass of CRT used in a typical CRT type display and display device (eg, TV, computer monitor, etc.) is expensive and high quality, so the value of recycling is very high. In addition, as described above in the background art, display displays have recently been replaced by LCDs, PDPs, or OLEDs, and CRT devices have been discarded. Therefore, in the embodiment of the present invention by recycling the glass of the Braun tube (Braun tube), to prepare a structure. In the following description, the CRT discarded for convenience of description will be referred to as a "closed CRT."

Recycling method of the waste brown tube according to the embodiment consists of the collection of the waste brown tube, separation of the glass portion from the waste brown tube, the regeneration process, the structure is manufactured by the forming and surface treatment process. Here, the structure may be, for example, a hollow foundation for installing street lamps, security lights, traffic lights, poles and the like. Of course, the present invention is not limited thereto, and the present invention can be applied to various devices that can use a structure using a material recycled from a closed CRT.

Hereinafter will be described a method of manufacturing a structure according to an embodiment of the present invention.

1 is a flow chart sequentially showing a method of manufacturing a structure according to an embodiment of the present invention.

First, the waste brown tube is collected (S100), and the glass portion is separated from the waste brown tube (S200). For example, a diamond cutter or wire is used to separate the front glass (panel) and rear glass (funnel) from the closed CRT and to remove the attached parts.

The glass separated from the closed CRT undergoes a regeneration process for manufacturing the structure before molding (S300). First, the separated glass is ground using a grinder (S310). At this time, the size of the crushed glass pieces or the particle size can be variously changed depending on the structure to be manufactured.

On the other hand, the glass used for the CRT is coated with lead for electromagnetic shielding, composite organic materials mainly based on carbon, inorganic materials such as zinc, manganese, silver, and copper, and the like, in particular, lead contaminates the environment. there is a problem. Hereinafter, for the convenience of description, lead, various composite organic materials, and inorganic materials coated on the glass surface are referred to as "impurities". Since such impurities are factors that pollute the environment as described above, a process of removing impurities before the molding step is performed (S330). For example, the glass is immersed in a container containing a lead separation liquid containing at least one selected from hydrochloric acid, methane, sulfonic acid, ethane, propanol sulfonic acid, and acetic acid. The lead coated on the glass is dissolved and separated from the glass. The glass is then immersed in pure water and washed to allow the dissolved lead to separate from the glass. In a separate container, a hydrofluoric acid dilution solution or a cleaning solution containing NaOH is charged and the glass pieces are immersed. This removes organic and inorganic materials coated on the glass surface. The glass pieces are then immersed in a wash bath containing pure water to wash the adsorbed hydrofluoric acid.

In the above, a process method of removing impurities by a wet method has been described. However, the present invention is not limited thereto, and impurities may be removed by a dry method.

After the removal of impurities, the glass pieces are charged into the melting furnace, and then heated to dissolve (S330). And when the melting process of the glass is finished, the molten glass is molded (S330). That is, after dissolving the glass dissolved in the molding die provided separately, it is cooled. At this time, the molding die is provided to correspond to the shape of the structure to be manufactured. The embodiment manufactures a structure used as the foundation of the street lamp, the shape may be, for example, trapezoidal shape. Detailed description of the method for producing a structure for supporting the street lamp column will be described below. When the molding is finished, the molded product is separated from the mold, which is a structure according to the embodiment.

On the other hand, even if the process of removing impurities from the glass during the regeneration process, it is difficult to completely separate the impurities from the glass. Thus, the surface treatment for coating the surface of the structure is carried out (S500). In the embodiment, the coating film is formed by wet dipping the structure in a liquid or paste engineering plastic paint or by painting paint on the surface of the structure. In this manner, by the coating film coated on the surface of the structure, impurities that may remain in the structure may be prevented from being discharged to the outside.

In the above, it demonstrated in order of dissolving glass after an impurity removal process. However, the present invention is not limited thereto, and a process of removing impurities during the dissolution step may be performed. That is, impurities such as lead, organic matter, and inorganic material coated on the glass of the CRT have a lower melting point (about 750 ° C. to 1200 ° C.) than the glass, so that the glass is in a gaseous state before or during melting. Is evaporated. The impurities are separated from the molten glass by evaporation. In this case, it is preferable to install a collector for collecting the gas of the evaporated impurities on the upper side of the melting furnace to recover the impurities.

Moreover, it is not limited to this, The method of oxidizing and evaporating the impurity contained in the said glass can also be taken by melt | dissolving glass in an oxidizing atmosphere.

The impurity removal step may be performed both before and after the dissolution process.
