Abstract

PURPOSE:To accurately measure temperature, by a method wherein a memory operating circuit, storing a larger output after an output from a thermometer is compared in order, is installed, and a data, stored in the circuit, is converted into temperature. CONSTITUTION:After an output signal measured by a thermometer 2 is amplified it is sampled at intervals of a given time based on a signal from a sampling signal generator A and is A/D-converted. It is then stored as a digital volume in a memory operating circuit C, and only a larger data is left after comparison of the sizes of the data with each other. This causes leaving of a maximum value of a single flue nozzle. The largest value is transmitted as the temperature data of the nozzle to a control room D. This enables the maximum value against the flue nozzle to be measured, to be found in order, whereby based on the value, temperature of each combustion chamber is found, the temperature of each combustion chamber is displayed by processing the data, and simultaneously, the combustion condition of each combustion chamber is controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a furnace temperature measuring device for a coke oven having a large number of carbonization chambers.

In general, a coke oven is formed of a furnace group in which independent carbonization chambers and combustion chambers are arranged alternately.On the other hand, the carbonization time in step 1, during which coal is charged into the carbonization chamber and then fired, is: Although it is influenced by external conditions such as the moisture content and particle size of the charged coal, most of it is determined by the temperature of the combustion chamber. Therefore, temperature measurement in the combustion chamber is one of the two important requirements for controlling coke production conditions.

Conventionally, combustion chamber temperatures have been measured manually using optical pyrometers, and have to be measured over a relatively short period of time. Moreover, even an experienced person has to spend a considerable amount of time fully equipped to measure one location, making it difficult to measure all combustion chambers in a short period of time, and there are also drawbacks such as large human errors. Ta.

In addition, as a temperature measurement method that does not use an optical high thermometer, the method of installing a thermoelectric pair in the fuel -: 3 = the upper space of the baked room, and the intermediate wall or upper part of the floating chamber or the upper part of the hairbin. There is a method of measuring by installing all the thermocouples on the surface j of the fire (1 The measured value of the turbulent force of 1st grade KJ2 pulsates, and there is a problem in grasping it as a representative value for the entire furnace. Both measurement methods have the disadvantage that there is a delay with respect to temperature changes inside the combustion chamber, and neither measurement method is a method of adding 1it7i and 0 to accurately grasping the total temperature inside the combustion chamber.

The object of the present invention is to provide an apparatus for measuring the temperature of a coke oven using a measurement vehicle equipped with a thermometer that makes full use of heat radiation by imprinting the flue nozzles while running the entire coke oven furnace. An object of the present invention is to provide a furnace temperature measuring device for a coke oven, which measures the temperature at each point of a flue nozzle continuously and determines the maximum IVli degree as the temperature of the combustion chamber in which the flue nozzle exists.

41 Another object of the present invention is to make the measurement vehicle run, stop, etc. based on signals from a control room outside the reactor, and also transmit measured data to the control room for all data processing. Another object of the present invention is to provide a complete furnace temperature measuring device that allows transmission and reception between a measurement vehicle and a control room no matter where the measurement vehicle is located.

Still another object of the present invention is to provide a complete furnace temperature measuring device that is capable of automatically charging a batch reel mounted on a measuring vehicle used for running the measuring vehicle.

Still another object of the present invention is to provide a furnace temperature measuring device that automatically opens and closes the furnace lid and measures the furnace temperature only for the flue nozzle to be measured.

The details of the coke oven furnace temperature measuring device of the present invention will be explained below. In order to measure the entire furnace temperature by measuring the light from the bottom of the furnace through a flue nozzle using a thermometer sound, for example, all thermometers installed on the rail installed in the direction of the furnace on the top of the coke oven. It is necessary to run the measuring vehicle and sequentially close and measure the lids of the flue nozzles to be measured. In this case, the temperature above the furnace other than the flue nozzle is also high, and the temperature measured through the flue nozzle with the lid open is relatively low around the opening and increases toward the center, reaching the highest temperature near the center. There is. Therefore, as mentioned above, run the measurement vehicle and pass through the entire flue nozzle to be measured.
Even if η is determined, it is necessary to determine all specific points in the opening of the flue nozzle and measure only the temperature at that point. However, there is a problem as to which point should be determined as the specific point.
Further, even if the center of the aperture is determined as the measurement point, there is a problem that it is not easy to control the measurement so that the measurement is always made at that point.

For the above reasons, in the present invention, the temperature based on the largest value among the continuously changing data measured through the flue nozzle is determined as the furnace temperature through the flue nozzle. σj1j constant lTi: measured with a thermometer through a trenched flue nozzle is sampled sequentially to a minute constant 111] mouth fσ, and the data obtained in the first sampling is compared with the data at the complete sampling point. As a result, the smaller one is completely erased, the larger one is stored, and this stored value is compared with the measured value at the next sampling point, and the same operation is repeated one after another.

In this way, the maximum value remaining at the end of all the measured values performed with one flue nozzle is determined as the temperature at that flue nozzle. In other words, as shown in the block diagram of Fig. 1, the output signal measured by the thermometer 2 is amplified by the amplifier circuit A, and then the output signal is transmitted at fixed time intervals or based on the signal from the sampling signal generator B. It is sampled every certain distance traveled by the measurement vehicle, and after A/D conversion, it is stored as a digital quantity in the calculation circuit C.
The data stored first is compared in size with the next data, the smaller value is deleted, and the larger value is kept. Further, the next sampled data is compared with the stored data and the smaller one is deleted. In this way, the largest value of one flue nozzle is left. This maximum value is transmitted to the flill all chamber 1 as the temperature data of the flue nozzle.

Since the maximum values for the flue nozzles to be measured in sequence are determined in this way, the temperature of each combustion chamber is determined based on these values. Furthermore, by processing the obtained data, the temperature of each combustion chamber is displayed, and the combustion state of each combustion chamber is fully controlled. A similar method can be used in which the analog outputs from amplifier A are sequentially compared in the data processing based on FIG. Also, amplification't! :i It is also possible to input the analog outputs of A and J in sequence and store only the highest value. Furthermore, the output of the thermometer 2 may be transmitted to the four control rooms, and the maximum value may be determined by sampling in the control room based on the received analog data.

Note that the output from the thermometer does not vary linearly with changes in the amount of incident light depending on temperature. For this reason, data processing may be performed after the output from the thermometer changes linearly with respect to changes in the amount of light, for example by using a near riser. In this case, when there is a time lag between the reception of light at different temperatures and the subsequent processing, it is desirable to run the measurement vehicle at a speed slower than the response speed. The autopsy vehicle used for measurements runs independently from the charging vehicle. Therefore, the time interval (for example, 2
It can be measured at 0 minute intervals).

Additionally, temperature can be measured at any time as needed.

Therefore, it is possible to control the furnace temperature by one degree,
It is effective for producing coke of uniform quality and for energy saving. In this way, in order to run the measurement car independently of the charging car, it is necessary to control it wirelessly from a control room or the like outside the furnace.

On the other hand, the charging car has a length equal to the length of the furnace in the furnace length direction, and runs over the furnace at regular intervals.

Therefore, it is possible that the measuring vehicle collides with the charging vehicle. However, among the charging cars, those with a rigid frame structure have a raised bottom in the center, and a hollow part of a certain height is formed between the charging car and the upper surface of the furnace, as shown later. In the present invention, for reasons to be explained later, the measuring vehicle is made to run entirely along a rail laid in the direction of the furnace 9 near the center in the longitudinal direction of the furnace.

For this reason, when using a charging car with a rigid frame structure (JF), the measurement car will run through the raised hollow area at the bottom of the charging car without colliding with each other. When it goes under the car, it becomes impossible to send and receive signals between the measurement car and the control room, and it becomes impossible to control the measurement car or receive data from the control room. ``To the means'': It completely eliminates this drawback.

Figure 2 is a complete view of the coke oven with the measuring wheel positioned below the charging car. In Fig. 2, E is a coke oven (E is a combustion chamber), F is a charging car with a rigid frame structure that has a hollow part F1 in the center with a raised bottom, and a charging car F1 is placed on top of the coke oven E. A rail 10 is laid through the hollow part F4 in the traveling direction of the furnace bundling shunting charging vehicle F,
The measurement vehicle 1 travels along this rail 10. G is the riser pipe installed in each carbonization chamber of coke oven/E, I-T
kj', -1 = collecting main that collects coke oven gas through all riser pipes, J is a bleeder provided at regular intervals in collecting main H for emergency discharge of coke oven gas, LXM is a transmitting/receiving anti' installed on charging vehicle F (measurement vehicle 1) and bleeder J, respectively.

As described above, since the charging car F1, the measuring car 1, and the bleeder J are each equipped with transmitting and receiving antennas, even when the measuring car 1 enters the charging car F, as shown in Fig. It can be controlled from the control room, and the data sent from the measuring vehicle 1 can be reliably received at the control room. Generally, as shown in FIG. 2, when the receiving or transmitting measuring vehicle enters the loading vehicle and is out of sight of the control room, the signal is no longer received due to directivity problems. However, in the device of the present invention, charging vehicle F
Since the data is transmitted and received via the antenna Ki attached to the antenna Ki, the data can be transmitted and received without any problem. In particular, since there are a large number of IJ-dar JFi at regular intervals, it is possible to transmit and receive with one antenna M attached to it, no matter what the positional relationship between the measuring tun and the charging tun. .

In the device of the present invention, the measuring wheel is run independently from the charging 1-f. For this purpose, the measurement vehicle runs as a battery laminate source mounted on itself. Therefore, it is necessary to fully charge this battery at regular intervals. Therefore, the device of the present invention is fully equipped with a device for automatically charging the battery f.

The automatic charging device included in the coke oven oven temperature measuring device of the present invention will be described below. FIGS. 3 to 5 are diagrams showing, for example, the vicinity of the measuring vehicle hangar, which is provided on the furnace outside the combustion chamber at the end of the furnace group, and in which a charging device and the like are provided. In these figures, 1 is a measurement car, and 2 is a thermometer that uses thermal radiation such as a monochromatic temperature sensor, a two-color thermometer, a three-color thermometer, a radiation thermometer, and an infrared thermometer. , 3.3' to -J, flue nozzle lid opening jrJ part A', 4.4 fJ-,

．． 4. (Details of 1f'l' will be described later), 5 is a battery mounted on the measuring vehicle 1, and 6 is a pantograph which is electrically connected to the battery and the charging device by contacting with a trolley described later.

Reference numeral 7 denotes a first limit switch, and when this switch is turned on, the limit switch operating piece 7a installed in the hangar stops the entire measuring vehicle and also connects the battery 5 and pantograph 6, which are normally disconnected. The structure is such that an electrical connection is made between the two. Also, 11 is a hangar, 1
2 is a protective fence, 13 is a charging device, 14 is a power cable 15
When the measurement vehicle 1 enters the hangar 11, the trolley is connected to the charging device 13 and connected to the pantograph 6. 16 is a second limit switch that issues a signal for charging and water sprinkling when turned on by an operating piece 16a provided on the measurement wheel 1; 17 is a water sprinkler control panel operated by the second limit switch 16; 18 is a water sprinkler device.

As will be described in detail later, when a measurement vehicle that measures the temperature through the entire flue nozzle while traveling along the rail 10 laid above the furnace enters the warehouse as shown in Fig. 3,
The first limit switch 7 installed on the measuring wheel 1 is turned on by the operating piece 7a, and the measuring wheel 1 stops. At the same time, the battery 5 and the pantograph 6 are electrically connected. Further, the pantograph 6 and the trolley 14 are connected.

As a result, the current from battery 5 is transferred to pantograph 6.
, the charging device 1 through the trolley 14 and the power cable 15.
Flows to 3. Although not shown, a circuit for detecting all of this current is provided within the charging device. On the other hand, the second limit switch 16 is an operating piece 16a provided on the measuring wheel 1.
It turns on.

The circuit within the charging device is switched to charging by the signal from the second limit switch 1G and the detection of the current from the battery 5. Thereby, the battery 5 is charged from the charging device 13 through the power cable 15, the trolley 14, and the pantograph 6. In addition, in response to a signal from the second limit switch 16, water is sprayed from the water sprinkler 8 onto the measuring wheel 1 by the water sprinkler control panel 17 to cool the battery.

After a predetermined period of time has elapsed from the start of light weight and the start of water sprinkling, charging and water sprinkling are stopped at approximately the same time at 14:00 by the action of a timer installed in the charging device 13 and the water sprinkling device control panel 11 17. The measurement vehicle whose battery has been charged in this manner is driven along the rail IOK to measure the temperature of the furnace. Furthermore, when it is necessary to measure the temperature before charging is completed and the measuring vehicle 1 is to be driven, the measuring vehicle 1 may be started by an external command. In that case, both the first and second limit switches are turned off, charging and watering are stopped, and the connection between the pantograph and the battery is also severed.

A complete diagram of the automatic charging system using the above-mentioned device is shown in FIG. 6. As shown in this figure, the temperature measurement by the measuring vehicle is completed■
2: The measurement vehicle is put into stock. When the vehicle enters the warehouse, the first limit switch 7 is turned on 11 and the measurement vehicle stops 1V, and the battery 5 and the pantograph 60 are electrically connected V. Further, when the measurement vehicle stops at a predetermined position, the pantograph 6 and the trolley 14 come into contact with each other. As a result, the battery 5 energizes the charging device 13 (V), and this current is detected IX. On the other hand, the second limit switch 16 is turned on V11 due to the arrival of the measurement vehicle H. Only when the above ■ and ■X meet J: does charging start X. Also, the second limit switch f": Start watering X1

After the predetermined temperature on the side is completed, the product is put into storage after 11 steps, and ■→XIV is repeated.

In addition, instead of the above-mentioned Mitsutswitch and 1st assistant piece,
Switches that detect the position, such as photoelectric switches and proximity switches, can be used.

Next, the measurement of temperature by running the temperature measuring vehicle will be explained. In a coke oven, generally, half of the burners in the combustion chamber that are connected in the longitudinal direction of the combustion chamber burn, and after a predetermined time, the other half completes combustion, and the side that was currently burning Complete combustion is performed by stopping and alternating this process. Furthermore, if the lid of the flue nozzle is opened during combustion, the temperature of the flame inside the combustion chamber must be measured, making it impossible to measure the desired temperature of the bottom brick surface. Further, the temperature of the combustion chamber is low on the side of the pusher 111 and increases with a temperature gradient toward the exit side of the kiln, and is highest on the exit side of the kiln. The average temperature of the combustion chamber is at the center in the furnace length direction. Therefore, measuring the temperature in the chamber from the flue nozzle force closest to the center of the flue nozzle on the side where combustion has completely stopped allows measurement of the average temperature of the combustion chamber without being influenced by the combustion in the chamber. I'm hopeful that this will happen.

Therefore, it is best to measure the row of flue nozzles that are closest to the center and lined up in the direction of the furnace cluster when combustion has stopped.

There are typically two types of structures for coke oven heating flame channels. One of them is a structural style typified by an Otto furnace. For example, in Fig. 7, each combustion chamber 21, 22
, 23, 24..., the odd-numbered combustion chamber 21.23
... is the extruder side 21a, 23a... is burned first, and the even-numbered combustion chambers 22, 24... are the kiln outlet side 22
b, 24. b... is burned, and after a certain period of time (for example, 20 minutes), the above-mentioned combustion completely stops, and on the other side, the odd-numbered ones burn on the exit side from the kiln, and the even-numbered ones burn on the extruder side. In other words, the burning part is the half divided from the center of each combustion chamber 17-.If we consider only the flue nozzle closest to the center of the combustion chamber, the broken line N in Fig. 7 is considered.
Or it becomes staggered like P. For this reason, if combustion is to be carried out continuously on the temperature side installed on the full temperature track for each combustion chamber in the direction of the furnace group, the part where combustion has stopped is run along the broken line N or P in Figure 7. There is a necessity to do so. However, it is possible to open and close the lid while making a humming sound, and to perform all measurements without stopping the vehicle.
In fact, it is difficult (condyle).

In the present invention, in the case of an Otto furnace, the broken line Q in FIG.
My father opened the lid of every other flue nozzle lined up in the R direction, measured the temperature, and then closed the lid in the direction of the furnace. Measurements should be taken for every other flue nozzle.

In Fig. 7, measurements are taken for the odd-numbered combustion chambers starting from the combustion chamber 21 along the broken line Q, and when the other end is reached, the measurements are made in the opposite direction so that 1ll11 is determined for the even-numbered combustion chambers. For this reason, in the above example of =18-, the lids of the even-numbered combustion chambers are not opened on the outward journey, and the lids of the odd-numbered combustion chambers are not opened on the return journey.

Next, in the structural style typified by the Karl Steel furnace, both combustion chambers are located on the same side (for example, the extruder side 21a,
22a...) is burned without reeds for a predetermined period of time (e.g. 20
The combustion is performed alternately at fixed time intervals in such a way that the opposite side (kiln outlet side 21b, 22b, . . . ) is burned after 1 minute).

Therefore, in the case of this type of furnace, it is sufficient to sequentially open the lid, measure, and close the lid of all the flue nozzles in the same direction on the side where combustion has completely stopped.

As mentioned above, measurements in the furnace group direction vary depending on the type of furnace, and in the case of an Otto furnace, measurements must be made every other time. The present invention is designed to enable measurement in any of the above cases as described in the following embodiments.

FIGS. 8 and 9 are diagrams showing only the measurement vehicle in its entirety, with FIG. 8 being a side view and FIG. 9 being a plan view. These figures are mainly for explaining the temperature measurement through the lid opening/closing and the flue nozzle, so the battery, limit switch, etc. are omitted to C. The lid opening member 3.3 shown in these figures is plate-shaped as shown in FIG. 10, and is supported by support plates 3a and 3'a. The lid closing member base 4' has a structure as shown in FIG. 11, is supported by support plates 4a and 4'aK, and can be rotated only in the direction indicated by the arrow in FIG.

FIGS. 12 and 13 are views showing the entire lid of the flue nozzle used in the present invention, with FIG. 12 being a plan view and FIG. 13 being a side view. In these figures, 40 is a cylindrical opening 1'' part of the flue nozzle, 41 is a lid, 42 is one end fixed to the side of the cylindrical opening 40 of the flue nozzle, and 1111143 is fully held: +++++ receiver is a part, 44 is a lid. A lid opening/closing plate is fixed to the shaft 43, 45 is an arm fixed to one end of the support 43, 4G is attached to the arm 45 by 1lill-17, and jl
(It is mounted so that it can be rotated by the lever connected to it.
47 and U so that it can be fixed or rotated. Reference numeral 48 denotes a stopper provided on the arm 45.

As shown in FIG. 14, the lever 46 in the above structure of the lid has a straight part 46a and a curved part 4.6b.
It is becoming more and more. Therefore, when the lever 46 is pushed in the direction of the arrow U, the lever 46 tries to rotate the entire length of the shaft 47, but the linear portion 46a hits the stopper 48 and pushes it further, so that the lever 46 and the arm 45 are separated. It rotates together with the support 43. By the rotation of the shaft 430, the lid opening/closing part 44, which is fixed to the shaft, rotates around the shaft 43, and the lid 41 is fully opened. On the other hand lever 46 full arrow W
When pushed from the side, only the lever 46 rotates around the shaft 47.

In the present invention, in the case of an Otto furnace, the lids having the above-mentioned structure are installed in alternating directions as shown in FIG. The measuring car 1 mentioned above is the 15th one.
As shown in the figure or FIG. 16, the robot moves along the rails laid on the furnace furnace, and repeats the sequence of opening the lid of only a predetermined flue nozzle → measuring → closing the lid.

21- Hereinafter, the measurement of the combustion chamber with l=1 will be explained using the furnace temperature measuring device of the present invention.

First, we will discuss the case of measuring in the direction of the furnace furnace in an Otto furnace. Now, the even-numbered combustion chamber 22.
24... on the extruder side 22a, 24. Suppose that a... is burning, and on the other hand, the kiln outlet +111121b, 231)... of the combustion chamber 21, 23... is burning.

In that case, for example, if measurement is performed on the extruder side, combustion of the odd-numbered units 21a, 23a, etc. has completely stopped, and measurement is possible. In this case, if the measuring wheel 1 is run from the direction of the combustion chamber 21 as shown in FIG. 15, the measuring wheel first reaches the flue nozzle of the combustion chamber 21. Here, since this flue nozzle is provided with a lid as shown in FIG. 15, the member 3 for opening the lid provided on the measuring wheel comes into contact with the lid 46. In this case, the lid opening member 3 pushes the lever 46 in the direction of the arrow U in FIG. 14, so that the lid is opened as already explained. As the measuring wheel 1 further travels, the thermometer 2 passes above the flue nozzle with the lid open, so that the temperature at the bottom of the hearth is measured 22-. Subsequently, when the lid is opened, the member 3' passes through the entire position of the lever 46, but since the lid is already open, there is no change. Further, since the lid closing member 4 comes into contact with the opened lid, the lid is pressed to close the lid. As the measuring car advances further, it reaches the flue nozzle of the combustion chamber 22, and the cover is opened when the lever 3 comes into contact with the lever. Since the even-numbered combustion chambers are provided with lids in the opposite direction to the odd-numbered combustion chambers, the lids are pressed in the direction of arrow W in FIG. 14). Therefore, only the lever 46 rotates and the lid is not opened. Similarly, when opening the lid, the cover member 3' also passes through. In this way, combustion chamber 2
The No. 2 overtone measuring vehicle passes without opening the lid and therefore without measuring the temperature. For the odd-numbered combustion chambers where combustion has stopped, the lid is opened, the temperature is measured, and the lid is closed, while for the even-numbered combustion chambers where combustion is in progress, the gas simply passes through. .

In this way, travel in the direction of the furnace group is completed, and temperature measurements of all combustion chambers where combustion has stopped are completed. After that, when the combustion point is replaced, if the measuring car runs in the opposite direction, J:
The operations of opening the lid, measuring the temperature, and closing the lid are performed, and for odd-numbered combustion chambers during combustion, no lid opening/closing or measurement is performed at all, and the chambers are simply passed through. In this way, when the measuring wheel returns to the starting position, temperature measurements for all combustion chambers are completed.

Next, the case of a Karl Steel furnace will be explained.

In the case of this type of furnace, a VJ: sea urchin lid shown in FIG. 16 is added to the flue nozzle used for measurement. Each combustion chamber has an additional lid facing the same direction. And open and close lay by the measuring car in this invention! When the combustion on the side with the lid on is stopped, the measuring wheel can be moved in a direction that allows the lid to be opened and closed.

In the case of Fig. 16, if the extruder side combustion is stopped, if you run from the combustion chamber 21 side to the other direction toward the furnace, the furnace for all combustion chambers will be Can measure temperature. Therefore, there is no reciprocating measurement, and after the measurement is completed, it is only necessary to return to the starting position before the next measurement starts.

In addition to measuring the combustion chamber temperature using rf, the lid may be opened for purposes such as observing or cleaning the interior of the chamber. If the measuring vehicle runs while the lid is left open, the lid closing member 4 may come into contact with the open lid. If the lid closing mechanism pushes the lid 41 further in the direction of opening the lid, as shown in FIG. 17, this may cause a malfunction. However, in the device of the present invention, as shown in FIG. 11, the lid closing member 4 can be rotated in the opposite direction to the direction in which the lid is closed, so that the device can run without any trouble. Furthermore, when a total of 111 tons has been traveled, the lid opening member 3' presses the lever 46 to close the lid, which means that the lid that was forgotten to be closed is closed, and temperature measurement from this flue nozzle is prevented. Moreover, there is no possibility that the upper lid closing member 4' will hit the lid.

FIG. 18 shows the entire structure of another furnace cover used in the apparatus of the present invention. This lid is fixed to the cylindrical opening 40 of the flue nozzle and has a lid 53 rotatably attached to the member 51 and 52 and having a hook 54. The lid is configured to be closed by a spring 55.

・In the case of a flue nozzle with a lid of this kind of structure, the hook 54 is attached to the contact plate 5G provided before and after the temperature sensor of the temperature sensor as the temperature sensor moves. You can open the lid by pushing in the direction.

And when the lid is opened, the temperature drops from the flue nozzle.
The temperature of the furnace is measured. After the measurement, the contact plate 5G is displaced by the hook 54.1=9*J, so the lid is automatically closed by the action of the spring 55.

When used in a differential oven of this type, it is necessary to attach the lid alternately in all directions for the reasons already explained. The lifts 54 are arranged alternately such that those on the left side and those on the right side in FIG.
There is a need to. And when the total tdll car is running, the abutting plate 56 closes every other lid? Open it and burn 1
It is necessary to measure the temperature by opening and closing only the lid of the combustion chamber that is stopped. Therefore, the contact plate 56 may come into contact with the hook 54 from the opposite direction (the direction opposite to the arrow in FIG. 18), which is undesirable. However, it is sufficient if the abutment plate 56 can be rotated only in the direction opposite to the direction of movement. As a result, the contact plate 56 is attached to the hook 5.
4 in the direction of the arrow in FIG. 18, the hook 54 is pushed to open the gap. On the other hand, when the contact is made from the direction opposite to the arrow, the hook 54 does not move, so the contact plate can rotate and move forward. Therefore, even if the hook placement position in the Otto furnace changes alternately, it can run and measure without any trouble.

Furthermore, the one shown in FIG. 19 differs from the one shown in FIG. 18 only in that the cylindrical opening does not protrude above the furnace, but is otherwise substantially the same. Therefore, the lid can be opened and closed using the contact plate having the structure described above. In order to open the lids of the structures shown in FIGS. 18 and 19, a roll or an L-shaped arm may be used as the contact plate instead of a plate-like one. Second
The lid shown in FIG. 0 has a quartz glass 57 installed at the upper end of a cylindrical opening 40 with a gasket interposed therebetween. In this case, the light and sound coming from the bottom of the furnace can be measured through the entire quartz glass 57, so a lid removing device is not required. However, since it is desirable to clean the entire surface of the quartz glass during measurement, it is preferable to provide a cleaning device instead of the lid removing device. FIG. 21 shows an example of this cleaning device. This cleaning device
:l Niji cylinder 61 and piston rod 62J with brush 63 provided at its tip: cleaning section and rTf, i
The conduit 64, the cylinder 67, and the nozzle 65 connected to the nozzle 65 through the pipe 6G''f are first taken out; car 1
It was installed near thermometer 2.

If the apparatus of the present invention equipped with such a cleaning device is dyed as described above, the brush 63 of this cleaning device will tighten the surface of the quartz glass, and the pressurized air from the conduit 64 will flow through all the nozzles 6.
5, the quartz glass surface can be cleaned and measured by spraying it from the direction of the body.

In addition, in the case of a flue nozzle covered with quartz glass as shown in Fig. 20, both the flue nozzle in the place where combustion is occurring and the flue nozzle in the place where combustion has stopped can be seen through the transparent quartz glass. All temperatures will be measured. However, which side of the combustion chamber burns and which side of the combustion chamber completely stops combustion is determined at predetermined time intervals through correct control.
: Therefore, it is easy to determine which of the measured temperature data is during combustion and which data is when combustion is stopped. Therefore, it is only necessary to select data when combustion is stopped during data processing.

In addition to the above-mentioned devices, temperatures can also be measured using the device of Kinoe IJ], even with structures that have been used in the past. In other words, in the case of such conventionally commonly used lids, a device with a full magnet at the tip is used as the lid removal device, and furthermore, this magnet does not move back and forth at position 1, which is outside the line connecting the temperature gauge and the flue nozzle. All you have to do is perform step a and use all the appropriate mechanisms.

When measuring the entire temperature of a combustion chamber equipped with a differential, which is commonly used in the past, using a furnace temperature measuring device equipped with a lid removal device as described above, the temperature of the flue nozzle should be measured by running the measuring vehicle all the way. After the thermometer is positioned above the thermometer, the thermometer is stopped once, and the magnet is lowered to attract and hold the differential. Measure all temperatures through the nozzle. Move the measurement diameter measuring wheel to the next flue nozzle to be measured at -1, stop it, and then measure using the same method. The coke oven furnace temperature measuring device i<t of the present invention Since the maximum value of the measured data is used as the furnace temperature of the combustion chamber where the flue nozzle is located, it is easy to determine the furnace temperature from the different measurement data at each point of the flue nozzle opening. , it is possible to measure the furnace temperature even when there is fluctuation in the temperature at each point. Therefore, the temperature measurement time is short and the device is
f't tll-. In addition, l'-Measurement tunnel d used for measurement: It is made to run independently apart from the charging 111. Since it is an I-type furnace, it is possible to perform measurements at short time intervals, and also to perform measurements at any time, making it possible to extremely finely control the furnace temperature 11.

Moreover, by using it on a charging vehicle with a rigid frame structure, it is possible to make the measuring vehicle run all the way regardless of the movement of the charging vehicle, and by using the full antenna on the charging vehicle and the bleeder, it is possible to connect the measuring vehicle and the loading vehicle. It is possible to send and receive data and command signals regardless of the mutual positional relationship of vehicles. Furthermore, the automatic charging device allows charging of the battery mounted on the measuring vehicle to be carried out fully automatically and safely. Further, in temperature measurement, the operations of opening the lid, performing one-step measurement, and then closing the lid can be performed automatically and sequentially only for specific flue nozzles to be measured.
