Description
Technical field
The invention belongs to winer construction engineering device technique field, and in particular to a kind of long-lived temperature measuring equipment of quick response.
Background technology
Steelmaking converter devaporizer automatic temperature control system is the core control portions of dry-dedusting system, and it is not only
It is related to dust removing effects and coal-gas recovering rate, and is related to the normal production of converter, the accurate measurement of its temperature is this again
The most important thing！Operating mode is special at this：Temperature in a short time can be from 1000 DEG C or so（1200 DEG C of blow off setting value）Drop to 200 DEG C
Left and right, this process only need the time of clock more than 2 points, and a cycle is 5 ~ 6 minutes；And contain substantial amounts of dust and corrosivity in cigarette vapour
Material, this proposes very high requirement to detection means；Or previously used temperature measuring equipment response speed is slow, or intolerant to
With.
Utility model content
The purpose of this utility model is the long-lived temperature measuring equipment for providing a kind of quick response.
The purpose of this utility model be achieved in that including thermocouple, protecting pipe, mounting flange, outer layer protection sleeve pipe,
Loose flange, described protecting pipe are set on thermocouple, and the terminals of one end connection thermocouple, and the other end is fixedly connected solid
Determine flange；Described outer layer protection sleeve pipe is also set on thermocouple, and one end is fixedly connected with loose flange, after other end sealing
Thermal hole, the working end of described thermal hole corresponding thermocouples are offered in the place from 3 ~ 7mm of termination；Described loose flange
It is flexibly connected with mounting flange.
Compared with prior art, the utility model has following technique effect：
1st, the utility model is huge suitable for measured medium temperature changing speed, amplitude, and contains dust and corruption in medium
The physical environment of corrosion, while fast response time and service life length, and effectively reduce cost.
2nd, the utility model fast response time, find in actual use, reach 1000 in present apparatus detection temperature
DEG C when, only measure 700 DEG C using conventional temperature-measurement device；The utility model service life is grown, and the utility model is in thickening Nai Mo
Convince hot hole on pipe by patient analysis, realize reaction speed soon while increase the service life, efficiently solve and responded in the prior art to pursue
Speed, protection sleeve pipe is made thin and washed away intolerant to dust, Gu and service life is short, and the too thick response speed of protection sleeve pipe is too slow
The problem of.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1- thermocouples, 2- protecting pipes, 3- mounting flanges, 4- outer layer protections sleeve pipe, 5- loose flanges, 6- thermal holes.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings, but the utility model is not subject in any way
Limitation, any conversion or replacement made based on the utility model training centre, belongs to the scope of protection of the utility model.
The utility model includes thermocouple 1, protecting pipe 2, mounting flange 3, outer layer protection sleeve pipe 4, activity as shown in Figure 1
Flange 5, described protecting pipe 2 are set on thermocouple 1, and the terminals of one end connection thermocouple 1, the other end are fixedly connected
Determine flange 3；Described outer layer protection sleeve pipe 4 is also set on thermocouple 1, and one end is fixedly connected with loose flange 5, and the other end is close
It is honored as a queen and thermal hole 6 is offered in the place from 3 ~ 7mm of termination, the working end of the described corresponding thermocouples 1 of thermal hole 6；Described
Loose flange 5 is flexibly connected with mounting flange 3.
Described thermocouple 1 is K-type thermocouple.
Described protecting pipe 2 is external diameter 6mm stainless steel sheath pipe.
Described outer layer protection sleeve pipe 4 is the high-abrasive material pipe that external diameter is 16mm.
Described loose flange 5 adds asbestos board with the junction of mounting flange 3.
Described thermal hole 6 is opened in the place from termination 5mm.
Described thermal hole 6 has 1 ~ 3.
Described thermal hole 6 is the one or more in circular, ellipse, rectangle.
Described thermal hole 6 is two through 6mm*20 mm rectangle thermal holes.
By the utility model compared with the temperature measuring equipment that the best ABB of existing combination property is produced：It is bent by thermometric trend
Line chart is compared, and the two whole process is synchronous, and response speed is enough fast；（Respectively install what a set of temperature measuring equipment was got in same operating point
Data）Service life：ABB for 3 ~ 4 months；The utility model opens the situation to observe, no Ren He Mo after using 6 months
Damage, Detection results are good, also can be used according to a preliminary estimate more than 1 year；The utility model cost only has ABB half, and because of outer layer
Protection sleeve pipe 6 can split with thermocouple 1, so can also be individually replaced.
Using the repair time, by the effective Φ 6 of K-type thermocouple well stainless steel make with mounting flange one, then use Φ
16 resistance to Mo tubes of material processes a relatively independent outer layer protection sleeve pipe, and a loose flange is welded in sleeve pipe one end, and the other end is close
It is honored as a queen and through two thermal holes of 6mm*20mm is opened in the place from termination 5mm, using so far, no abrasion.
Utility model works principle and the course of work：This temperature measuring equipment is first arranged on operating point to be measured, adjusted during installation
Whole thermal hole 6, to protect the working end of thermocouple 1 not washed away by dust；During work, test substance passes through outer layer protection sleeve pipe 4
On thermal hole 6 be in contact with the working end of thermocouple 1, thermocouple 1 responds rapidly to temperature；Outer layer protection sleeve pipe 4 is wear-resisting material
Expects pipe, and there is thicker tube wall, thus resistance to dust wash away it is corrosion-resistant；Loose flange 5 is flexibly connected with mounting flange 3, when
Outer layer protection sleeve pipe 4 have abrasion need change when, be individually replaced, cost reduced so as to save process, loose flange 5 with
The junction of mounting flange 3 installs asbestos board additional can effective leakproof.Observed using the present apparatus is removed using furnace outage time after a period of time,
This rotatable pipe 180 degree if finding that the wall of outer layer protection sleeve pipe 4 has Mo damages, i.e., stop washing away for dust using opposite side（When
Thermal hole 6 can be realized when being two through thermal holes）.
