Abstract
The utility model discloses a kind of blast furnace cross temperature measuring equipment for being conveniently replaceable temperature-measuring part, is used as measurement blast furnace center or subcenter temperature installed in 100 front end of blast furnace cross thermometric body.One is set to be used as the outer tube 210 that armoured thermocouple replaces passage outside the protection first 230 of armoured thermocouple 220 and thermocouple sheath 240.Having between the outer tube 210 and protection first 230 can make armoured thermocouple in outer tube interior axle to mobile gap K.The utility model need not extract apparatus body after cross temperature measurer draws money on credit central point or the damage of short branch subcenter point, you can thermocouple and its protection head are replaced, significantly cutting down human and material resources and time needed for replacement.
Description
Technical field
The utility model belongs to metallurgy high furnace equipment, is distributed for monitoring charge level gas temperature in stove.
Background technology
Current blast furnace cross temperature measuring equipment is elongated rod shape steel construction, mainly by thermometric body and splitting on thermometric body
Multiple temperature thermocouples form, thermometric body play the role of support and protection thermocouple, below it is separated by a distance just
It can arrange a thermocouple.Wherein, the thermocouple of temperature measuring equipment front end is used for monitoring the central temperature of blast furnace charge level.But
With the continuous improvement of rate of driving, blast furnace center gas temperature is higher and higher, especially for the blast furnace of centre of development, such as wraps
The blast furnace centers such as steel, capital Tang, Anshan iron and steel plant, this steel, Yingkou, An Gang, Nanyang, Sha Gang 5800, subcenter gas temperature often exceed
1000 DEG C, transient temperature can reach 1300 DEG C -1400 DEG C, and central point or subcenter point thermocouple are (as shown in Figure 1, long branch center
Point A, short branch subcenter point B) often it is burned, can not long-time service.
It can be seen that from conventional temperature measuring point damaged condition：Central point, subcenter point thermocouple and protection head are in the condition of high temperature
Under, protect head and thermo-electric metal part to soften, wearability drastically reduces, under the coal gas with dust washes away in blast furnace, one
Fix time it is interior first thermocouple protection head is ground away, cause thermocouple break.Due to being filled with height in the thermocouple protection head that blows
Stove dust, under blast furnace staying state, more than 90% thermocouple can not be extracted out from afterbody to replace thermocouple.Even if there is percentage
Several possibility performances extract old thermocouples out, new thermocouple can't be accurately installed in place, and can not ensure temperature measurement accuracy, at the same time also
Once undertake thermocouple to pull off, the risk that whole cross temperature measurer is scrapped.So above-mentioned blast furnace is all to utilize blast furnace staying machine
Can take 4-6 it is small when the time will cross temperature measurer extract out blast furnace after more renew thermocouple again.So operation will be spent very big
Human and material resources and time, and if the blast furnace staying time short can't replace.
Utility model content
In view of the disadvantage mentioned above of the prior art, the purpose of this utility model, which is that design is a kind of, new is conveniently replaceable temperature-measuring part
Blast furnace cross temperature measuring equipment, be allowed to be completed to ten with a small amount of human and material resources and time in the state of blast furnace staying
Word temperature measuring equipment draw money on credit central point or short branch subcenter point thermocouple and its protect the replacement of head, with overcome the prior art with
Upper shortcoming.
The purpose of this utility model is realized by following means.
The blast furnace cross temperature measuring equipment of temperature-measuring part is conveniently replaceable, is used as installed in 100 front end of blast furnace cross thermometric body
Measure blast furnace center or subcenter temperature.One is set to use outside the protection first 230 of armoured thermocouple 220 and thermocouple sheath 240
Make the outer tube 210 that armoured thermocouple replaces passage, one end of the outer tube 210 is overlapped on cross temperature body body 100
On, the other end couples with first flange 260；Protection first 230 and thermocouple sheath 240 couple with second flange 250；The overcoat
Having between pipe 210 and protection first 230 can make armoured thermocouple in outer tube interior axle to mobile gap K.
Using the structure of the utility model, on the basis of common cross temperature measurer, cross temperature measurer (draw money on credit or
Short branch) inside has newly increased central point or the armoured thermocouple of subcenter point replaces passage.As central point or the short Zhi Cizhong of drawing money on credit
After heart point thermocouple and its protection head are burned, during damping down, by thermocouple, thermocouple sheath and first of thermocouple protection
Replace in passage and extract out from central point (or subcenter point), then replace thermocouple and thermocouple protection head, then be inserted into more
Passage is changed, completes to replace.
Using design as above, the utility model is drawn money on credit in cross temperature measurer after central point or the damage of short branch subcenter point
Apparatus body need not be extracted, you can to thermocouple and its protection head replace, such characteristic make the utility model have with
Lower advantage：
1. new thermocouple can accurately in place；
2. replacement cost is low；
3. replacing construction is short, a thermocouple is less than 30 minutes.
While human and material resources needed for replacement and time is significantly cut down, also allow complete within the shorter blast furnace staying time
The replacement of paired thermocouple and its protection head is achieved.

Embodiment
The utility model is described in further detail with example below in conjunction with the accompanying drawings.
The blast furnace cross temperature measuring equipment of temperature-measuring part it can be seen that, is conveniently replaceable, installed in blast furnace cross thermometric body by Fig. 2
100 front ends are used as measurement blast furnace center or subcenter temperature.In the protection of armoured thermocouple 220 first 230 and thermocouple sheath 240
Outer to set one to be used as the outer tube 210 that armoured thermocouple replaces passage, one end of the outer tube 210 is overlapped on cross temperature sheet
On body body 100, the other end couples with first flange 260；Protection first 230 and thermocouple sheath 240 and second flange 250
Connect；Having between the outer tube 210 and protection first 230 can make armoured thermocouple in outer tube interior axle to mobile gap K.
In this way, the utility model is the increase of central point or short branch subcenter point of drawing money on credit in former cross temperature measurer body
Outer tube 210, to serve as the replacement passage of new and old thermocouple.
