Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a burner angle measuring device for a glass melting furnace capable of measuring the burner angle with high accuracy.

[0002]

[Prior Art]

 The heavy oil burner of the glass melting furnace must be changed regularly, and when setting a new burner in the melting furnace, it must be set while measuring the mounting angle of the burner. This is because if the burner were set to be tilted, it would not be possible to obtain a stable combustion state in the glass melting furnace.

[0003]

[Problems to be solved by the device]

 By the way, conventionally, since the burner angle is measured with a commercially available goniometer, (1) high measurement accuracy cannot be obtained, (2) measurement takes about 10 minutes, (3) handheld There is a problem that it can not be measured unless it is attached to the burner, (4) it is vulnerable to heat because it is made of plastic, (5) it is difficult to measure in a narrow place.

In particular, since the burner of the glass melting furnace is installed in a narrow place where the receiving metal fittings and pipes of the bricks constructing the furnace are concentrated and the atmosphere temperature thereof is installed at a high temperature of 150 to 200 ° C., There is a problem in that measuring the burner angle with the goniometer will be a difficult task.

Therefore, an object of the present invention is to provide a burner angle measuring device for a glass melting furnace, which solves the problems of the above-mentioned conventional techniques and enables the burner angle to be measured easily and accurately. Especially.

[0006]

[Means for Solving the Problems]

 To achieve the above object, the present invention comprises a bracket fixed to a burner holder and a gauge main body supported by the bracket, and the gauge main body has a gauge rod that swings according to the burner angle. The burner angle is measured by reading the swing angle of the gauge bar on a scale.

[0007]

[Action]

 According to the present invention, the gauge body is attached to a place relatively distant from the glass melting furnace, and the ambient temperature there is lowered to 80 to 130 ° C. Therefore, when measuring the angle, the temperature is relatively low. It becomes possible to measure in place. Moreover, the gauge body has a gauge rod that swings according to the burner angle, and the swing angle of this gauge rod is read on a scale, and the burner angle is measured by this, so the swing angle is 1 °. On the other hand, for example, if the scale is increased to about 5 mm, the burner mounting angle can be measured with higher accuracy than the conventional one.

【Example】

 An embodiment of a burner angle measuring device for a glass melting furnace according to the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a heavy oil burner attached to a glass melting furnace, and a burner holder 3 for holding the burner 1 is attached to a shaft portion of the burner 1. When installing the new burner 1 in the melting furnace, the mounting angle of this burner 1 becomes a problem. That is, if the burner 1 is not installed horizontally, a stable combustion state of the glass melting furnace cannot be obtained.

Therefore, according to this embodiment, the angle measuring instrument 5 is attached to the shaft portion of the burner 1, and the attachment angle of the burner 1 is accurately measured using this. The angle measuring device 5 is made of iron, and includes a bracket 7 fixed to the burner holder 3 and a gauge body 11 supported by the bracket 7 via a gauge supporting rod 9.

As shown in FIG. 2, the bracket 7 is configured by inserting a screw rod 17 between two plates 13 and 15 and fixing a handle 19 to an end of the screw rod 17. Guide members 21 and 23 are interposed between the two plates 13 and 15, and one guide member 21 is fixed to the plate 13 and has a hole 21a at its end. Further, the other guide member 23 is fixed to the plate 15 and has a protrusion 23a at its end which is inserted into the hole 21a. According to this, by rotating the above-mentioned handle 19, the dimension between the plates 13 and 15 is adjusted, and the movement at this time is guided by the guide members 21 and 23.

A support rod holder 27 is attached to the plate 15 via an L-shaped stay 25. The support rod holder 27 is provided with a gap 27a having a size large enough for the gauge support rod 9 to be sandwiched therein. There is.

As shown in FIG. 3, the gauge body 11 is fixed to the end portion of the gauge support rod 9, and the gauge body 11 is attached to the suspension bar 31 and the lower end of the suspension bar 31. A frame 37 fixed via zero-point calibration bolts 33, 35, a scale 39 provided on the lower frame of the frame 37, and a swingable suspension from the upper end of the frame 37 for indicating the scale 39. And a gauge bar 41 to be used.

According to this, when the gauge body 11 tilts, the gauge rod 41 swings, and the degree of the tilt is read by the scale 39. At this time, the zero point of the gauge rod 41 is adjusted in advance by the zero point calibration bolts 33 and 35.

As shown in FIG. 4, the lower end of the gauge rod 41 is cracked into a fork shape, and the lower frame of the frame 37 is fitted in the groove 41a at the lower end thereof. According to this, even if the gauge main body 11 is largely tilted, the gauge rod 41 does not come off from the lower frame of the frame 37, so this configuration is convenient for angle measurement.

To mount the angle measuring device 5 on the burner 1, first, while turning the handle 19, the burner holder 3 is sandwiched between the two plates 13 and 15, and thereby the bracket 7 is fixed to the burner holder 3. At this time, the size between the two plates 13 and 15 may be set to be slightly larger than the thickness of the burner holder 3 (about +0.5 mm) in advance to reduce the operation by the handle 19.

Next, the gauge body 11 is connected to the bracket 7 via the gauge support rod 9. The gauge support rod 9 is connected to the support rod holder 27 of the bracket 7. Since the spring ball 29 is attached to the support rod holder 27, the attachment and detachment can be performed with one touch. In this case, it is desirable to adjust the zero point of the gauge rod 41 in advance. This is because if the zero point is adjusted once, it does not shift so much even if the temperature changes, and it is easier to make the adjustment in advance. The installation of the angle measuring device 5 is completed by this operation.

When mounting the burner 1, if the burner 1 is mounted at an angle, the gauge rod 41 swings in accordance with the tilt.

Therefore, if the inclination is read on the scale 39, the mounting angle of the burner 1 can be measured. Here, when the angle of the burner 1 is tilted by 1 °, for example, if a difference of 5 mm appears on the scale 39, the tilt of the burner 1 can be measured with higher accuracy than the conventional one. You can

According to the above configuration, it is not necessary to carry out the measurement while holding the angle measuring instrument. Therefore, the measurement time can be significantly shortened (about 2 minutes), and the measurement error can be reduced. Since there are no individual differences in the measured values of angles, it is possible to obtain various effects such as always obtaining stable measured values.

[0021]

[Effect of the device]

 As is clear from the above description, according to the present invention, the gauge body has the gauge rod that swings according to the burner angle, and the swing angle of the gauge rod is read on the scale, and Since the burner angle is measured, if the scale is set to a large value, for example, about 5 mm for a swing angle of 1 °, the burner mounting angle can be measured with higher accuracy than the conventional one. You can
