Detailed Description
(description of embodiments of the invention)
First, embodiments of the present invention will be described.
A glass material container according to an embodiment of the present invention,
(1) which contains a liquid glass raw material, vaporizes the contained glass raw material, and supplies the glass raw material to a glass synthesizing apparatus, wherein the glass raw material container is made of metal,
in the glass material container, a glass window is provided on a side surface of the glass material container.
According to the above configuration, since the glass window is provided on the side surface of the metal glass material container, contamination in the glass material container can be directly visually recognized through the glass window. This makes it possible to determine whether or not the glass material container needs to be cleaned.
(2) The glass window comprises a glass and a metal window frame part,
the glass is fitted into the window frame portion in direct contact with the window frame portion and sealed so that the glass material does not leak from the glass material container.
According to the above configuration, since the glass is fitted into the sash portion so as to be in direct contact with the sash portion and sealed, the glass is excellent in airtightness, and the glass material can be prevented from leaking to the outside.
(3) The glazing may have a first glazing part in which the inner first glass is embedded and a second glazing part in which the outer second glass is embedded.
According to the above structure, the glass of the glass window is double. Thus, when the first glass on the inner side is broken, the glass material can be prevented from leaking to the outside of the container through the second glass window portion on the outer side. In addition, the impact from the outside of the container can be prevented from directly hitting the first glass on the inside.
(4) The second glass window section has a second glass and a second metal window frame section,
the second glass may be embedded in the second window frame portion via a packing.
According to the above configuration, the second glass window portion does not directly contact the glass material, and therefore, it is not necessary to provide a tight airtightness. Therefore, the second glazing unit may also use a packing. In addition, when the packing is used, the second glass can be easily removed when performing inspection of the glass window or the like. Further, the glass can be fitted more firmly against an impact from the outside of the container than the glass can be directly fitted.
(5) It may be that there are at least two of said glazing,
the other glass window is provided at the same height position on the side surface opposite to the side surface of the glass material container on which the one glass window is provided.
According to the above configuration, since the glass window is also provided on the opposite side of the container, for example, by lighting the lamp, the inside of the glass material container can be easily observed from the outside of the glass window on the opposite side. This makes it easier to visually observe the contamination in the glass material container and the height of the liquid surface. For example, the height of the liquid surface can be detected by a sensor by attaching a light-emitting sensor to the outside of one window and a light-receiving sensor to the outside of the other window.
(details of the embodiment of the present invention)
Next, a specific example of the glass material container according to the embodiment of the present invention will be described with reference to the drawings.
The present invention is not limited to these examples, but is defined by the claims, and includes all modifications within the meaning and range equivalent to the claims.
(first embodiment)
An example of a glass material container according to a first embodiment will be described with reference to fig. 1 to 3.
As shown in fig. 1, the glass material container 1 includes a container body 2 and a glass window 3, and the glass window 3 is provided on a side wall 21 of the container body 2. The glass material container 1 of the present example can be used as a container for containing, for example, a liquid glass material and supplying the vaporized glass material to a glass synthesizing apparatus.
The container body 2 is a storage portion for storing the liquid glass material a, and is formed in a cylindrical shape having an upper bottom and a lower bottom, for example. Liquid silicon tetrachloride (SiCl) is stored in the container main body 2 in a sealed state4) Germanium tetrachloride (GeCl)4) And liquid glass raw material a. The container body 2 is made of metal, and is made of, for example, stainless steel material (e.g., SUS 316L) having high corrosion resistance. The vessel body 2 may be structured such that a metal layer having corrosion resistance is formed by plating the inner surface in contact with the stored glass material.
A glass raw material supply pipe 11, a carrier gas supply pipe 12, and a raw material gas supply pipe 13 are attached to an upper wall 22 of the container main body 2. The glass material supply pipe 11 is a supply pipe for supplying the liquid glass material a to the container main body 2. The carrier gas supply pipe 12 is a supply pipe for supplying a carrier gas B made of an inert gas such as argon, helium, or nitrogen into the liquid glass raw material a stored in the container main body 2 by bubbling. The raw material gas supply pipe 13 is a supply pipe for supplying a raw material gas generated by vaporizing the liquid glass raw material a in the container main body 2 to a burner (not shown) of the glass synthesizing apparatus. The carrier gas is mixed with the raw material gas and supplied to the burner of the glass synthesizing apparatus together with the raw material gas.
The liquid glass material a supplied from the glass material supply tube 11 is usually supplied to a predetermined height, for example, a position C, in the container main body 2 by controlling the supply amount by a flow rate control unit (not shown).
The glass window 3 is formed to protrude outward from the side wall 21 of the container body 2. The glass window 3 is formed at a height corresponding to the position C of the glass raw material a for supplying liquid into the container main body 2. In the example shown in fig. 1, the glass window 3 is a double glazing window, and includes a first glass window portion 3A and a second glass window portion 3B, an inner first glass 32 is fitted into the first glass window portion 3A, and an outer second glass 34 is fitted into the second glass window portion 3B. The glass window 3 may have at least a first glass window portion 3A.
Further, the detailed structure of the glass window 3 will be described with reference to fig. 2, and fig. 2 is a cross-sectional view taken along line D-D of the glass material container 1 of fig. 1.
As shown in fig. 2, the window glass 3 is attached to an attachment hole 21a formed in the side wall 21 of the container body 2 via an intermediate connection member 23. The intermediate coupling member 23 is formed in a cylindrical shape, and is made of a metal material such as a stainless steel material (e.g., SUS 316L) having high corrosion resistance, as in the case of the container body 2. The intermediate connection member 23 has one end (left end in fig. 2) welded to the side wall 21 of the container body 2 and the opposite end (right end in fig. 2) welded to the end of the first window glass portion 3A.
The first window portion 3A includes a first window frame portion 31 and a first glass 32, and the first glass 32 is attached to the first window frame portion 31.
The first window frame portion 31 is made of metal, and is formed of, for example, a stainless steel material (e.g., SUS 316L) having high corrosion resistance, a carbon steel material, or the like. The first window frame portion 31 is formed in a substantially cylindrical shape, and has a concave portion 31a formed to have a small outer diameter and a convex portion 31b formed to have a large outer diameter. The end portion (left end portion in fig. 2) of the concave portion 31a is welded to the intermediate connection member 23 in the first window glass portion 3A.
The first glass 32 is fitted and sealed by shrink fitting inside the convex portion 31b of the first window frame portion 31 so that the outer peripheral surface of the first glass 32 directly contacts the inner peripheral surface of the first window frame portion 31. The first glass 32 preferably has a heat-resistant temperature of about 200 ℃, and for example, soda glass, borosilicate glass, or the like can be used. The thickness of the first glass 32 is 4mm to 5 mm.
The second window portion 3B includes a second window frame portion 33 and a second glass 34, and the second glass 34 is attached to the second window frame portion 33.
The second window frame portion 33 is made of metal, and is formed of a stainless steel material (for example, SUS 316L) or a carbon steel material, as in the case of the first window frame portion 31. The second window frame portion 33 is formed of two window frame portions (an inner window frame portion 35 and an outer window frame portion 36) formed in a substantially cylindrical shape. The inner window frame portion 35 has a convex portion 35a formed with a small inner diameter and a concave portion 35b formed with a large inner diameter. Similarly, the outer sash portion 36 has a convex portion 36a formed with a small inner diameter and a concave portion 36b formed with a large inner diameter.
The inner window frame portion 35 and the outer window frame portion 36 are disposed on the outer peripheral side of the first window frame portion 31, and are disposed so as to face each other so as to sandwich the convex portion 31b of the first window frame portion 31 from both sides (from the left-right direction in fig. 2). A plurality of bolt holes 37 are formed in the inner window frame portion 35 and the outer window frame portion 36 at the same intervals in the circumferential direction. The second window frame portion 33 has a structure in which the convex portion 31b of the first window frame portion 31 is gripped between the convex portion 35a of the inner window frame portion 35 and the convex portion 36a of the outer window frame portion 36 by fastening the second window frame portion with the bolt 38.
The second glass 34 is sealed by being fitted into the inner side of the outer window frame portion 36 of the second window frame portion 33 via a packing 39 such as rubber. The second glass 34 is held between the convex portion 35a of the inner window frame portion 35 and the convex portion 36a of the outer window frame portion 36 together with the convex portion 31b of the first window frame portion 31. The second glass 34 is provided so as to cover the first glass 32 on the outer side (right side in fig. 2) of the first glass 32. For example, the second glass 34 has a thickness of 2mm or more and 3mm or less and a diameter of about 30 mm.
Similarly to the second glass 34, the first glass 32 may be fitted into the first window frame portion 31 via a packing and sealed. The second window frame portion 33 may be formed of another material having rigidity equivalent to, for example, metal, since it does not come into direct contact with the stored liquid glass raw material a.
As shown in fig. 3, in the present example, the outer frame portion 36 of the second frame portion 33 is fastened by 8 bolts 38. The interior of the container main body portion 2 can be visually observed through the second glass 34 set in the central portion of the outer window frame portion 36.
According to the glass material container 1 having the above-described configuration, since the glass window 3 is provided on the side wall 21 of the sealed metal glass material container 1, contamination in the glass material container 1 can be directly visually recognized through the first glass 32 and the second glass 34 of the glass window 3. Therefore, it is possible to easily determine whether or not the inside of the glass material container 1 needs to be cleaned. In addition, the position of the liquid surface of the glass material stored in the glass material container 1 can be easily confirmed.
Further, since the first glass 32 is fitted into the first glass 32 by thermocompression bonding and sealed so as to be in direct contact with the first window frame portion 31, the airtightness of the first window portion 3A can be improved. Therefore, even if the temperature of the glass material container 1 changes, for example, there is no fear of deterioration because no packing is used for sealing, and the material in the glass material container 1 can be prevented from leaking to the outside from the first window glass portion 3A.
Further, by providing the second window glass section 3B outside the first window glass section 3A, the window glass 3 can be made to have a double structure. Therefore, even when the inner first glass 32 is broken, for example, the glass material can be prevented from leaking to the outside of the container by the outer second glass window portion 3B. Further, the outer second window glass portion 3B can prevent an impact from outside the container from being directly applied to the inner first glass 32.
In addition, the second glass window portion 3B does not directly contact the glass material, and therefore, strict airtightness is not required. Therefore, the second glass 34 can be sealed with, for example, a packing, and the manufacturing cost can be suppressed. In addition, when the packing is used, the second glass 34 can be easily removed when inspecting the glass window 3 or the like, and thus the workability is good. Further, the structure can be made stronger against an impact from the outside of the container by fitting the packing material, as compared with directly fitting the glass.
(second embodiment)
An example of a glass material container according to a second embodiment will be described with reference to fig. 4.
As shown in fig. 4, the glass material container 5 has two glass windows 3 and 3 in a side wall 21 of the container body 2. Note that the same components as those of the glass material container 1 of the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.
The two glazings 3, 3 are arranged in positions opposite to each other. That is, the other glass window 3 is provided at the same height position of the glass material container 5 with respect to the side wall 21 opposite to the side wall 21 provided with the one glass window 3. This position is a position having a height corresponding to the position C of the glass raw material a to be replenished with liquid, as in the first embodiment.
Further, a lamp (flash lamp or the like) may be provided on the outer side of, for example, the second glass 34 of any one of the two opposing glass windows 3. For example, a light-projecting and light-receiving sensor may be prepared, and a light projector may be provided on the outer side of one of the two glass windows 3 facing each other, and a light-receiving sensor may be provided on the outer side of the opposite glass window. The glass window 3 may be provided at a position corresponding to the position C and at another height of the side wall 21.
According to the glass material container 5 configured as described above, since the glass windows 3 and 3 are provided at the positions facing each other in the side wall 21 of the container main body 2, the inside of the glass material container 5 can be easily observed from the outside of the glass window on the opposite side by lighting the lamp. This makes it possible to easily visually check the contamination in the glass material container 1 and the height of the liquid surface.
Further, if the light-projecting and light-receiving sensor is used as described above, the height of the liquid surface can be detected without being visually observed through the glass window. Further, the amount of the glass raw material to be supplied can be controlled by the flow rate control unit based on the information on the liquid level detected by the sensor.
While the present invention has been described in detail and with reference to the specific embodiments, it will be apparent to one skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope thereof. The number, position, shape, and the like of the constituent members described above are not limited to those in the above embodiments, and may be changed to appropriate numbers, positions, shapes, and the like in order to implement the present invention.
