Automatic method of measuring temperature for coke furnace and system of measuring temperature

[0024] Example 1: Such as figure 1 , 2 , 3 and 5, a coke oven automatic temperature measurement system, composed of a temperature measurement track 1, an automatic temperature measurement device 2, a brush type communication head 3 and a host computer 6, the temperature measurement track 1 is set in the coke oven 5 The ring track outside the furnace surface coal loading car track 11, the standing fire channel 8 exit in the temperature measurement track 1 is a standard temperature measurement hole 7; the brush type communication head 3 is located above the ring temperature measurement track, and the brush type communication head 3 is connected to the host computer 6 set in the coke oven operating room through the communication line 4; the automatic temperature measuring device 2 is equipped with a computer and an optical probe, and can automatically walk on the temperature measuring track 1 to measure the temperature through an external mains.

[0025] The automatic temperature measurement method is: let the automatic temperature measurement device 2 loaded with temperature measurement probes walk on the temperature measurement track 1, and the temperature measurement probe on the temperature measurement device 2 passes through the standard vertical fire channel temperature measurement hole located in the temperature measurement track. 7 Perform actual measurement of the temperature in the furnace, the automatic temperature measuring device 2 will collect the temperature data through the brush type communication head 3 set at a point above the temperature measurement track, and transmit the measured temperature data to the ground through the wired communication line The upper computer 6, the upper computer 6 obtains the temperature of each standard vertical fire channel (the vertical fire channel used for temperature measurement) by analyzing and calculating the sampling curve data and controls the coke oven heating system; automatic temperature measurement device 2 The time for the temperature measuring probe to pass through a temperature measuring hole is: the width of the temperature measuring hole-2 times the width of the probe/the speed of the temperature measuring car; the sampling times of the temperature measuring device passing through a temperature measuring hole is: the time the probe passes through the temperature measuring hole/ The sampling period.

[0026] Example 2: Such as figure 1 , 2 , 3, 4, 6, 7, 8, 9, 10, 11 and 12, a coke oven automatic temperature measurement system, consisting of a temperature measurement track 1, an automatic temperature measurement car 2, an electric brush communication head 3 and The upper computer is composed of 6, and the brush type communication head is connected with the upper computer through the communication line 4. The temperature measurement track 1 is an annular track set on the inner side of the coal charging car track 11 of the coke oven 5, and the exit of the standing fire channel 8 located in the temperature measurement track is a standard temperature measurement hole 7; the brush type communication head 3 is located in the ring temperature measurement Above the track 1; the automatic temperature measuring car 2 consists of a car body 14 with thermal insulation effect, a computer 23 installed in the car body 14, an optical probe 10, a driving device, and a power supply 22 that provides power for the computer, optical probe and driving device Composition; The upper cover 29 of the car body 14 can be opened, and the cover is equipped with a brush 30 opposite to the brush 3. The rear wheel 16 of the car body 14 is the driving wheel, and the front wheel 20 is the driven wheel; the driving device is composed of a motor 12 and a transmission gear. The transmission gear on the axle 15 of the driving wheel 16 is engaged with the motor gear; on the car body 14, the optical probe 10 There is a transparent probe window 18 underneath. The probe window is a round window protruding from the bottom surface of the car body 14; the car body 14 is equipped with a cover opening device and a cover closing device for opening and closing the 7-hole cover of the temperature measuring hole. The cover opening device is a pull rod 19 installed under the vehicle body; the cover closing device is a cover closing roller 13, in which the shaft gear is engaged with the motor gear, and there are three wheel arms 17 of the cover closing roller. The hole cover 24 of the standard temperature measuring hole 7 is equipped with an automatic opening and closing device. The device is composed of a cross bar 28 and a vertical rod 27 and its hinge 26 welded on the hole cover. The included angle is 90 degrees, and the hinge 26 is located at the intersection of the vertical rod and the horizontal rod. The front end of the vehicle body 2 is equipped with an anti-collision ultrasonic probe 21.

[0027] The optical probe of this system selects Raytech MARATHON series: MA2SC), and the ultrasonic probe selects sonaswetchMene-A. Set the temperature measuring car 2 to continuously pass the standard standing fire track 8 on the circular temperature measuring track 1 at a speed of about 1m/s. At each temperature measuring hole 8, the lid opening and pulling rod 19 and the lid closing roller 13 on the temperature measuring cart 2 can automatically complete the actions of opening, measuring, and closing the lid, and the optical probe 10, which is always in the measuring state, passes through the temperature measuring hole. More than 100 vertical fire channels (9 is the light in the vertical fire channels) of the focusing furnace are used for continuous and dynamic real-time scanning measurement. Since the sampling period of the optical probe 10 is 2ms and the width of the temperature measurement hole is about 8cm, the optical probe Through a temperature measuring hole of a standing fire channel, it can be sampled continuously for about 20 times.
