The present invention relates to a glass curette manufacturing apparatus for producing a glass powder for display, and more particularly to a glass curlet manufacturing apparatus using a forming roller to extend the roller life by preventing damage to the roller surface.

In general, the method for producing a glass powder for display is as follows. First, the glass raw material blended to have a desired composition is melted in a melting furnace to prepare a homogeneous melt. Then, the molten glass is solidified to prepare a glass cullet. The glass curette thus prepared is pulverized several times to produce finely divided glass powder having a uniform particle size distribution.

In general, there is a method of manufacturing a glass curette is a method of directly quenching a molten glass having a high temperature of 1200 degrees or more directly into the water. However, when the molten glass is poured into water to produce a glass curette, the glass powder is manufactured in a bulk form, and thus, even when the glass powder is pulverized in a subsequent process, the glass powder is not uniform in particle size, large in particle size, and uniform in particle size distribution. There is a problem that it is difficult to use for PDP.

In addition, the glass curette prepared in this way has a problem that it takes a lot of energy and time to crush the glass particles into fine powder in the subsequent grinding process, because the glass itself has a high hardness characteristics, the crushed glass particles contain a large amount of water By doing so, there is a problem in that a process of drying the moisture is added.

The method of manufacturing the glass curette by the water-cooling method as described above has a problem that water is contained in the pulverized glass particles, and thus, a molding roller crimping method has been proposed as a method for improving this.

This forming roller method is a method of injecting hot molten glass between two rollers to cool and solidify by the roller surface to produce a curette.

However, since the molding roller pressing method injects the hot molten glass between the rollers along one turbidity, the width narrows narrowly with respect to the length direction of the roller, and only the injected molten glass portion directly contacts the roller surface. . Therefore, there is a problem in that local overheating occurs on the surface of the roller during long time operation, and wear and contamination of the roller surface easily occur. Such damage to the roller surface will eventually degrade the quality of the glass powder.

The present invention has been made to solve the problems as described above, and an object thereof is to provide a glass curette manufacturing apparatus using a molding roller to prevent surface damage of the roller while cooling and solidifying the hot molten glass.

It is a front view which shows the positional relationship of the protrusion guide part of a discharge guider, and the grinding blade of a grinding board.

As shown in Figs. 1 to 8, the glass curette manufacturing apparatus 100 using the forming roller according to the present invention is mounted on the main frame 10 and the main frame 10 above the main frame 10. The guide member 20 which guides the flow of the molten glass 11 in the direction of the shaping | molding roller 30, and the crushing apparatus 40 which grind | pulverizes the plate glass 41 are provided.

The guide member 20 is mounted above the main body frame 10 to guide the flow of the high temperature molten glass 11. The molten glass 11 is manufactured by injecting a mixed material of the composition constituting the glass into the hot melting furnace 13 to melt it. The raw material used for the molten glass can melt all the glass compositions used as the glass powder for display in the case of the present invention, so the detailed description of the specific raw material composition and each composition ratio of the mixed composition is omitted. The molten glass 11 in such a high temperature molten state is guided to flow to the forming roller 30 through the guide member 20.

As described above, the guide member 20 guides the flow of the molten glass 11 in the molten state to the forming roller 30 of the main frame 10, and the material thereof has a composition with the composition of the hot molten glass. A metal or refractory having a low reactivity is preferably used, and preferably one composed of platinum. In the case of platinum, its physical and chemical properties are very stable to air and moisture, and it does not change even when heated to high temperatures. It is resistant to acids and alkalis and is excellent in corrosion resistance. Therefore, even when the molten glass 11 in the high-temperature molten state is moved through the guide member 20, structural deformation or chemical deformation of the guide member 20 does not occur, thereby making stable movement.

The guide member 20 supplies the molten glass from the melting furnace 13 to the proximal position of the main body frame 10 through one path, and from the proximal position of the main body frame 10 to the upper side of the main body frame 10. Can be supplied in two channels. This one path and the supply path of the molten glass 11 through a plurality of paths branched therefrom is a preferred embodiment of the present invention, it is also possible to consist of a plurality of consistent paths from the melting furnace to the upper side of the main frame 10. Of course.

In more detail with reference to the drawings, from the melting furnace 13 to the proximal position of the forming roller 30 is provided with a refractory hot water 21 for guiding the molten glass 11, through the refractory hot water 21 The guider 23 which distributes the falling molten glass 11 to the shaping | molding roller 30 through several branches is provided. In a preferred embodiment of the present invention, the guider 23 allows the molten glass 11 to be supplied to the forming roller 30 through at least two or more preferably three branched paths. This is to prevent the partial wear and damage of the forming roller 30 by supplying the molten glass 11 is distributed in several parts instead of intensively supplied to only one portion in the longitudinal direction of the forming roller 30. to be.

The refractory water flow passage 21 includes a conduit 22 through which the molten glass 11 moves, and a refractory 24 mounted inside the conduit 22. One end of the conduit 22 is in communication with the bottom of the melting furnace 13, and the other end is preferably extended to the upper side of the forming roller 30. The material of the pipe line 22 is preferably made of platinum material to prevent damage by the molten glass (11). As shown in FIG. 4, the guider 23 is formed with a recess 27 extending in the longitudinal direction, so that the guide action of the molten glass 11 is smoothly performed. That is, the molten glass 11 in the molten state has a high viscosity, so that the flow guide action is easily performed without overflowing to the outside of the guider 23 even if the concave portion 27 is formed. The concave portion 27 is an embodiment of the present invention, and the guider 23 may be provided in a plate shape without the concave portion 27. As described above, since the external overflow of the molten glass 11 is not generated due to the viscosity of the molten glass 11, it is possible to have a plate shape.

In addition, the guider 23 is a portion of which is fixed to the side of the refractory waterway 21 and extends from the portion fixed to the refractory waterway 21 to directly inject the molten glass to the roller in the direction perpendicular to the extended portion The injection guiders 23a, 23b, 23c are further extended, and the part fixed to the refractory water supply 21, the extended guider 23, and the injection guiders 23a, 23b, 23c for injecting molten glass are integrally formed. It can be formed as. Here, the injection guiders 23a, 23b, and 23c for injecting molten glass may be formed in a plate shape, and when the guider is formed in a plate shape, a groove is formed in a portion to which the molten glass 11 is to be injected, thereby forming the groove part. Portions of the molten glass 11 flowing through the injection guiders 23a and 23c through the injection roller 30 are injected. Grooves formed in the injection guiders 23a and 23c may be formed in accordance with the number of branches of the molten glass 11 to be supplied. However, preferably, the molten glass 11 flowing in the upper portion of the injection guiders 23a and 23c by forming one groove in the center portion 23b of the injection guider is formed at both ends 23a and 23c of the injection guider. It is injected into the forming roller through the groove 23b, that is, through the three branches.

Here, the shape of the injection guiders (23a, 23b, 23c) is inclined toward the forming roller both ends (23a, 23c) starting from the center (23b), so that the molten glass 11 flowing through the injection guider by gravity It flows easily toward the forming roller.

The forming roller 30 is provided in a pair of rotational driving in a state in which the outer circumferential surfaces are close to each other, so that the molten glass 11 is compressed to maintain a predetermined thickness to be formed of a plate glass 41. Reference numeral 31 denotes a drive motor for driving a forming roller. Cooling water is supplied to the inside of the forming roller 30, and at the time of the pressing action of the high temperature molten glass 11, the cooling operation is also performed so that the pressurized molten glass 11 is kept below a predetermined temperature. The plate glass 41 which is pressed and formed together with such a cooling action is pulverized to a predetermined size by the operation of the crusher 40 described later.

The surface of the forming roller 30 is nitrided using ammonia gas or nitrogen gas. This is because when the molten glass is pressed into a plate-like solid state by a forming roller, the wear of the glass to which the glass is pressed is intensified, because the hardness of the glass itself is high. In the case of nitriding the surface of the forming roller, about 5 to 30 μm is preferable from the surface. As such, when nitriding the surface of the forming roller, the surface hardness of the forming roller itself is kept high while the surface slipperiness is excellent and the adhesion resistance is excellent. In addition, when the forming roller is nitrided, wear resistance and corrosion resistance of the nitrided forming roller become very high.

The grinding device 40 is composed of a discharge guider 45 and the grinding unit 44.

The discharge guider 45 guides the discharge of the plate glass 41 solidified and discharged into the plate shape while the molten glass 11 is cooled by the forming roller 30. The upper surface of the discharge guider 45 is provided with a plurality of protruding compartments 43 protruding in the longitudinal direction from which the pane 41 is discharged. And the crushing unit 44 is provided with a rotating shaft 47 so as to be mounted to cross the upper portion of the projecting partitions (43). On the rotary shaft 47, a pulverizing plate 49 is formed in which the protruding blade 42 protrudes along the circumference and pulverizes the solidified plate glass 41.

As shown in FIG. 5, the discharge guider 45 is fixed to the main body frame 10 so that the rollers of the forming roller 30 are located in the direction of the direct contact with each other. And the discharge guider 45 guides the discharge of the plate glass 41 discharged in the state solidified in the plate shape by the forming roller 30. In the longitudinal direction of the discharge guider 43, that is, the longitudinal direction in which the plate glass 41 is discharged, a plurality of projecting partitions 43 are formed. The plurality of protruding compartments 43 serve to support the plate glass 41 when crushing the plate glass 41 from which the crushing unit 44 is discharged. In addition, the protruding portion 43 serves to partition the discharge path of the plate glass 41 in which the protruding portion itself is crushed so that the crushed plate glass 41 is discharged into a plurality of branches.

The grinding unit 44 is a circular grinding plate 49 is fixed on the rotary shaft 47, a plurality of grinding blades 42, such as saw blades are formed on the outer peripheral surface of the grinding plate 49. The grinding blade 42 is made of a pointed shape of the tip so that the plate glass 41 can be broken. A plurality of crushing plates 49 fixed to the crushing unit 44 are fixed along the longitudinal direction of the rotary shaft 47, and crushing plates 49 which are even-numbered with the central axis of the crushing plate 49 at odd-numbered positions. ) Center positions are mounted in an deviated arrangement, that is, eccentrically. In addition, the positions at which the crushing plates 49 are mounted on the rotation shafts 47 are positioned between the protrusion partitions 43. In addition, as shown in FIG. 8, the minimum length a from the rotating shaft 47 of the pulverizing part to the end of the crushing blade 42 of the pulverizing plate 49 is the distance from the rotating shaft 47 of the pulverizing part to the end height of the protruding partitions 43. The crushing unit 44 is fixed to the crushing device 40 so as to be longer than the distance b.

As such, the plate glass 41 discharged by installing the crushing device 40 is priced by the grinding blade 42 of the pulverizing unit 44 rotating. 43) and are eventually crushed to a certain size. On the other hand, the grinding plate 49, as shown in Figure 6, when looking at the other end direction from one end of the rotary shaft 47, the central position mounted on the rotary shaft 47 is located eccentrically in turn. Therefore, when the crushing blade 42 strikes the plate glass 41, the price position on the plate glass 41 discharged becomes a zigzag form or a W-shape, so that the plate glass 41 is evenly distributed in the longitudinal direction as well as in the width direction. To be crushed.

Therefore, the discharged plate glass 41 is dispersed in the priced position by the grinding blade 42, so that the grinding action of the plate glass 41 is smooth and the discharge is made smoothly.

Hereinafter, a method of manufacturing a wave glass curette using the glass curette manufacturing apparatus using the above-described forming roller will be described.

First, a glass raw material is mixed and charged in the hot melting furnace 13, and a glass raw material is melted. The molten glass 11 melted in the melting furnace is discharged through the refractory water supply 21 of the guide member 20. The molten glass 11 discharged through the refractory water supply 21 is injected between the rollers of the shaping roller 30 through the guider 23.

When the molten glass 11 moves through the guider 23, the molten glass 11 is not injected directly into one path but is injected between the rollers of the forming roller 30 through a plurality of paths, that is, three paths. The molten glass 11 flows into the forming roller 30 through three paths of the guider 23, so that the surface of the forming roller 30 is caused by local contact with the molten glass 11. Phosphorus damage can be minimized.

Subsequently, the shaping roller 30 solidifies the injected hot molten glass 11 and simultaneously compresses and discharges the molten glass 11 into a plate having a constant thickness. Since the coolant flows inside the shaping roller 30, the molten glass injected into the shaping roller 30 is cooled and solidified while contacting the roller surface and discharged from the shaping roller in the form of plate glass 41. do.

Next, the solidified plate glass 41 is crushed to a predetermined size through the crusher 40. Grinding through the grinding device 40 of the present invention is the primary grinding process, and then is manufactured in a powder state by an additional grinding process through a separate device. The pulverization of the plate glass 41 is pulverized by a pulverizing plate 49 mounted to be rotatable with the rotation of the rotary shaft 47 in the horizontal direction in which the plate glass 41 is discharged.

The present invention has been described above with reference to the embodiments shown in the drawings.
