えた溶融ガラス貯槽に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a molten glass storage tank. More specifically, the present invention relates to a molten glass storage tank equipped with a flow rate adjusting means that can easily and accurately adjust the flow rate of low-viscosity molten glass to a desired level.

させ、流出する流体23の流出量を調節する方法
が知られている。 Conventionally, the method of flowing high temperature viscous fluid such as glass through an orifice while adjusting the flow rate is as follows.
As schematically shown in Figure 1 of the accompanying drawings, the plunger 22, which is not inserted into the narrow passage of the orifice 21, is moved up and down so that the central axis of the plunger and the orifice coincide with each other, and the liquid flows out. Methods for regulating the outflow amount of fluid 23 are known.

調節精度が悪い欠点があつた。 However, although the structure of the plunger and the method of operating the plunger in the conventional method can be used to adjust the flow rate of fluids that normally have a viscosity of several hundred poise or more, In the case of fluid, the misalignment between the center axis of the plunger and the center axis of the orifice, which tends to occur when the plunger is moved up and down, results in large flow rate fluctuations, and therefore the relationship between the vertical movement distance of the plunger and the flow rate also changes. It was difficult to adjust, and the flow rate adjustment accuracy was poor.
しかるに、本考案者らは、低粘度溶融ガラスを
貯えた貯槽から低粘度溶融ガラスの流量を所望の
流量に容易に且つ高精度で調節して流出すること

る。 That is, the present invention is a molten glass storage tank in which bottom viscosity molten glass is stored so as to have a free surface, and the low viscosity molten glass is caused to flow out in the direction of gravity by adjusting the flow rate through an orifice provided at the bottom. , the orifice comprises a passage whose cross section in a direction perpendicular to the direction of passage of the low-viscosity molten glass has a circular cross section having substantially the same area, and an insertion rod having a tapered circular cross section;
The insertion rod is suspended vertically in a height-adjustable manner from a support that allows relatively free movement;
This suspended insertion rod is a molten glass storage tank characterized in that the molten glass present in the molten glass storage tank is constantly brought into contact with the passage side wall of the orifice by the horizontal flow of glass.

ラスの流出がつづけられる。 In the present invention, the flow rate of the low-viscosity molten glass flowing out through the orifice is controlled by an insertion rod inserted into the passage of the orifice, which can move up and down in the direction of gravity within the orifice to change the effective fluid passage area of the orifice. is adjusted by changing the insertion depth. The insertion rod is inserted into the passageway while the insertion rod is in contact with a side wall of the passageway,
After the insertion depth is set constant, the low-viscosity molten glass continues to flow out.

That is,
By changing the insertion depth of the insertion rod into the orifice passage, the effective fluid passage area of the orifice, that is, the area obtained by subtracting the cross-sectional area of the insertion rod at that position from each cross-sectional area in the length direction of the orifice passage. Since the area showing the minimum value changes, the flow rate of the low viscosity molten glass is adjusted.

窯内に溶融ガラスの流れが存在する。 In the reservoir of the invention, such an insertion rod is constantly brought into contact with the side wall of the orifice passageway by the horizontal flow of molten glass present in the reservoir. Generally, in a molten glass storage tank such as a glass melting kiln in which an orifice is provided at the bottom end, a flow of molten glass exists within the kiln.

理解されよう。 From FIGS. 3 and 4, when the insertion rod is brought into contact with the inner wall of the orifice and low viscosity fluid flows out according to the present invention, there is an almost linear relationship with the insertion depth of the insertion rod into the orifice. It can be seen that the outflow amount of low viscosity fluid fluctuates. Therefore, according to the present invention, the outflow amount of low-viscosity molten glass is approximately proportional to the insertion depth of the insertion rod into the orifice. In other words, the desired outflow amount is almost independent of the absolute amount of outflow amount. Since the insertion depth of the insertion rod to be changed can be kept approximately constant, it is very easy to precisely control the outflow amount. In addition, since the insertion rod is in contact with the side wall of the orifice, it is hardly displaced by the flow of low-viscosity molten glass, and therefore a constant flow rate can be stably supplied over a long period of time. You can also keep doing it. This can be understood, for example, by comparing line a' and line b' in FIG. That is, as mentioned above, line a' is the result obtained according to the present invention when the insertion rod is in contact with the side wall of the orifice, and line b' is the result obtained when the insertion rod is placed in the center of the orifice. Because it is a result,
For example, when the insertion rod is inserted into the orifice at a depth of 20 mm, there is a difference in the amount of low viscosity fluid flowing out between the two. When used, it is understood that the amount of fluid flowing out may vary within a range of approximately 40 Kg/hr even with the same insertion depth of 20 mm due to horizontal displacement of the insertion rod. It will be.

According to the inventor's research, for low viscosity fluids of, for example, 10 to 100 poise, the design of the insertion rod, such as the orifice diameter, the diameter of the tip of the insertion rod and the attachment part, and the length between the tip and the attachment part. It has been shown that by appropriately selecting the following, it is possible to easily achieve a fluid flow rate of about 100 Kg/hr or less.

本考案により達成される効果をまとめて示せば
以下のとおりである。 The effects achieved by the present invention are summarized as follows.
(1) 挿入棒のオリフイスへの挿入深さと低粘度溶
融ガラスの流量とがほぼ直線関係を示す状態を
広い流量範囲にわたつて作り出すことができる
ため、流量調節の精度が向上する。(1) Since it is possible to create a state in which the depth of insertion of the insertion rod into the orifice and the flow rate of low-viscosity molten glass show an almost linear relationship over a wide flow rate range, the accuracy of flow rate adjustment is improved.
(2) 挿入棒がオリフイスの側壁に接触しているた
め、挿入棒の挿入深さを変化させても、上記直
線関係を安定して確保しつづけることができ、
それ故流量調節操作に再現性がある。(2) Since the insertion rod is in contact with the side wall of the orifice, even if the insertion depth of the insertion rod is changed, the linear relationship described above can be maintained stably.
Therefore, the flow rate adjustment operation is reproducible.
(3) 貯槽内に挿入棒に横方向からの力を与える低
粘度溶融ガラスの流れが存在し且つ挿入棒が吊
下げられているため、挿入棒は該流れにより絶
えずオリフイス側壁に押しつけられた状態を保
つので、挿入棒の変位による流量変動がなく、
従つて流量調節安定した流量で低粘度溶融ガラ
スを流出しつづけることができる。(3) Since there is a flow of low-viscosity molten glass that applies a lateral force to the insertion rod in the storage tank and the insertion rod is suspended, the insertion rod is constantly pressed against the orifice side wall by the flow. , so there is no flow rate fluctuation due to displacement of the insertion rod.
Therefore, the low viscosity molten glass can continue to flow out at a stable flow rate.
(4) 挿入棒は単に金属製ワイヤ等によつて吊下げ
るだけで良く、従つて部品も少なくてすみまた
維持も簡単である。(4) The insertion rod can be simply suspended by a metal wire or the like, so the number of parts is small and maintenance is easy.
(5) 挿入棒の上方根元にオリフイスを閉塞し得る
ストツパー部を設けることによりワイヤの張力
を解除するだけで挿入棒は自重で落下しオリフ
イスは閉塞されるもので、緊急時に低粘度溶融
ガラスを訊速且つ容易に停止することができ
る。(5) By providing a stopper part at the upper base of the insertion rod that can close the orifice, simply by releasing the tension on the wire, the insertion rod will fall under its own weight and the orifice will be closed, making it possible to use low-viscosity molten glass in an emergency. It can be stopped quickly and easily.
