本考案は、コークス炉の装入炭高の測定装置に
関するものであり、詳しくは、装入炭高を精度よ
く測定し得る装入炭高の自動測定装置に関するも
のである。[Detailed description of the invention] The present invention relates to a device for measuring the height of charged coal in a coke oven, and more specifically, to an automatic measuring device for the height of charged coal that can accurately measure the height of charged coal. be.
コークス炉において、装入炭高と焼成時間とは
密接な関係にあるため、装入炭高を精度よく管理
すれば、焼成時間のバラツキを減ずることがで
き、この結果、乾留所要熱量を低減することがで
きる。 In a coke oven, there is a close relationship between the charging coal height and the firing time, so if the charging coal height is accurately managed, the variation in firing time can be reduced, and as a result, the amount of heat required for carbonization can be reduced. be able to.
従来、装入炭高を自動的に測定する方法として
は、錘を下げたワイヤーを装入口から下げて荷重
が変化するまでのストロークによつて炭高を算出

式は錘の装入炭内への埋没などによつて測定精度
が悪く、さらにワイヤーの寿命にも問題がある。
また、マイクロ波方式は測定器周辺の環境が限定
され、設置場所の選定が困難であることなどから
実用化はされていない。 Conventionally, methods for automatically measuring the charging coal height include the weighted sounding method, in which a weighted wire is lowered from the charging port, and the coal height is calculated by the stroke until the load changes; A microwave method is known that calculates distance by receiving microwaves reflected from the coal surface. However, the sounding method has poor measurement accuracy because the weight is buried in the charged coal, and there are also problems with the lifespan of the wire.
Furthermore, the microwave method has not been put into practical use because the environment around the measuring device is limited and it is difficult to select the installation location.
本考案は、コークス炉炭化室という高温（800
〜1000℃）かつ発生ガスによる圧力変動が激しい
悪環境下においても、装入炭高を直接かつ精度よ
く測定できる安価な装置を提供するものである。 This invention is based on the coke oven carbonization chamber, which is a high-temperature (800℃)
The objective of the present invention is to provide an inexpensive device that can directly and accurately measure the height of charged coal even under adverse environments with severe pressure fluctuations caused by generated gas.

定を行う際には、−数十mmAq〜＋300mmAq程度の
範囲で激しく変動する。 The temperature varies from about 100 to 200 degrees Celsius at the beginning of charging to about 1000 degrees Celsius just before leaving the kiln. On the other hand, pressure always exhibits a unique behavior different from that of the atmosphere, and a large amount of gas (coke oven gas, steam) is generated by charging coking coal. Therefore, when measuring the charged coal height after charging coking coal and the subsequent leveling work, the height of the charged coal fluctuates wildly in the range of -several tens of mmAq to +300 mmAq.

To provide a device capable of measuring high temperatures.

よい。 The measurement of the charging coal height is started by the driver of the charging vehicle turning on a switch (not shown) in the driver's cab after charging the raw coal and the subsequent leveling of the charging coal. The input of the switch activates the cylinder 13 of the drive equipment, and the measuring tube 9 is lowered into the carbonization chamber 8 . When the measuring tube 9 descends, the long tube 1
0 comes into contact with the charged coal 2 before the short pipe 11, and the long and short pipes 10 and 11 are connected to the compressed air feed pipe 14, as described above.
Since air of the same pressure is sent from 14',
A pressure difference occurs between the long pipe 10 and the short pipe 11, and the pressure difference detector 16 detects this pressure difference. Note that the set pressure of the differential pressure detector 16 may be, for example, 30 mmAq.

る。 Based on the signal from the differential pressure detector 16, the drive control mechanism 23 stops driving the cylinder 13 of the drive equipment and opens the electric valves 20, 20'.
21 and 21' are closed, and an alarm is sent to the calculation display mechanism 25. On the other hand, the stroke measuring device 24 consisting of a position transmitter continuously transmits signals to the calculation display mechanism 25 while the driving equipment is driving, and stops the transmission when the driving equipment stops driving. The signal from the device 24 is stored in the calculation/display mechanism 25 as the moving distance of the measuring tube 9 within the carbonization chamber.

Then, the height of the charged coal in the carbonization chamber 8 is calculated, and the height of the charged coal is displayed on a display board (not shown) provided at an appropriate position in the operator's cab or the like.

ある。 The above has described a method of feeding compressed air at the same pressure into the compressed air feed pipes 14 and 14' and detecting the differential pressure that occurs between the pipes 14 and 14'. It is also possible to keep the differential pressure between the long pipe 10 and the short pipe 11 constant and detect a change in the differential pressure between the two pipes due to the long pipe 10 being grounded to the coal seam.
ちなみに、差圧検知方式による本考案装置と重

また、測定所用時間は本考案装置を用いると約半
分以下となり応答時間は大幅に短縮される。 By the way, when comparing the device of the present invention using the differential pressure detection method and the conventional device using the weight type sounding method, the measurement accuracy of the conventional device is ±100 mm, while the measurement accuracy of the device of the present invention has decreased to ±50 mm.
Furthermore, when the device of the present invention is used, the time required for measurement is reduced to about half or less, and the response time is significantly shortened.
以上説明したように、本考案の装入炭高の測定
装置は長管と短管の圧力差検知方法であるため、
装入炭装入直後の炭化室の圧力変動および測定管
の降下に伴う圧力増などの影響を受けず、従つて
上述のように測定精度が向上し、同時に検出速度
も著しく早くなり、適正な乾留所要熱量を的確に
算出できるので、所要熱量の低減を図りうる。 As explained above, since the device for measuring the charged coal height of the present invention is a method for detecting the pressure difference between the long pipe and the short pipe,
It is unaffected by pressure fluctuations in the coking chamber immediately after charging coal and pressure increases due to the descent of the measuring tube, and therefore, as mentioned above, measurement accuracy is improved, and at the same time, detection speed is also significantly faster, allowing for proper detection. Since the amount of heat required for carbonization can be accurately calculated, it is possible to reduce the amount of heat required.
