According to the temperature measuring device disclosed by the utility model, the defect that the temperature measuring meter is damaged due to expansion and concentration changes is overcome, the service life is prolonged, the measuring precision is improved, accurate data are provided for high-efficiency iron making of the blast furnace, accurate data are provided for reasonable air feeding and operating of the hot air furnace, and the production continuity is ensured.
Description
Technical field
The utility model relates to a kind of blast-furnace hot-air temperature measuring equipment, belongs to the temperature survey field.
Background technology
Blast furnace ironmaking provides hot blast as reductive agent by hotblast stove, require hotblast stove to provide continuously rational hot blast (～0.35MPa to blast furnace,～1200 ℃), be connected by pipeline between blast furnace and hotblast stove, its connecting tube is commonly called as hot air duct, and because temperature is too high, lining brick is wanted in its inside, with insulation, and avoid hurting sb.'s feelings.Because its operating mode is high temperature and high pressure environment, its temperature detection is very difficult; There are at present two kinds of detection methods.The one, adopt the stainless steel protection pipe to be combined with temperature instrumentation; protective tube is positioned at the lining brick (same section inwardly generally is built into by the artistic brick of three layers of different size differing materials by shell) of hot air duct; due to degree of expanding with heat and contract with cold difference inside and outside pipeline; after work for some time; stainless steel protection Guan Yi is by three layer process brick distortions; cause the temperature instrumentation fracture, even it is also quite of short duration to change its life-span, wastes substantial contribution and delay production.The 2nd, adopt whole instrument brick (containing pre-opened hole) to add the temperature instrumentation form, whole instrument brick is installed in pipeline, and temperature instrumentation inserts in the instrument brick, by filling in thing with temperature instrumentation and instrument brick jam-pack, puts forth effort; Due to degree of expanding with heat and contract with cold difference inside and outside furnace wall, after work for some time, its brick deforms, and easily interdicts temperature instrumentation, can only change the thinner temperature instrumentation of caliber during replacing, and the life-span has a greatly reduced quality; There is no stationary installation when installing due to temperature instrumentation, blast furnace production is again continuous, and the effect that temperature instrumentation is under pressure is easily loosening, because there is certain space in the opinion in temperature instrumentation and instrument brick hole, thereby easily causes its resonance, very easily damages temperature instrumentation.And must stop production as long as just change or overhaul.
Summary of the invention
The purpose of this utility model is: provide a kind of rational in infrastructure, safe and reliable, measure relatively accurate, long-lived a kind of blast-furnace hot-air temperature measuring equipment.
In order to overcome the defective that exists in background technology, the technical scheme that the utility model provides is: a kind of blast-furnace hot-air temperature measuring equipment comprises temperature instrumentation, whole instrument brick, mounting flange adapter.
Described temperature instrumentation, the flange of a kind of same standard bore of first processing and manufacturing is (according to the standard of China, the mode of connection kind of temperature instrumentation is a lot, the protective tube diameter is a lot, and its corresponding size for connection kind is also a lot, is unity, be batch production, we all use the joint flange of same bore, are connected with production unit, pipeline with convenient), batch production; Make a high temperature resistant stainless steel pipe, this pipe welds with joint flange is concentric again, consists of a flange connecting pipe; Make again a temperature instrumentation that meets the thermometric requirement, the band stationary installation; Instrument and flange connecting pipe are connected and fixed, consist of whole temperature instrumentation.
Described instrument brick, the swell increment of its material and process high-temperature brick is complementary, and center and section leave pre-opened hole, fire through high temperature (1600 ℃) to form, and its inner aperture of reserving can not change; Namely consider expanding with heat and contract with cold in its work, consider again its thermal conduction, also consider the fixing means of itself and temperature instrumentation; The instrument transform shape of avoiding expanding with heat and contract with cold and causing is reduced and to be caused the injury (high temperature) that may cause the people because safeguarding because of temperature conduction; For increasing crushing resistance, the section of instrument brick is fixed a joint flange, reserve joint bolt, consist of the indeformable structure of globality.Be mounted to integratedly with whole temperature instrumentation again, the thrust of hot blast is single direction, even produce displacement, is also globality, and is harmless to the temperature instrumentation of inside, effectively protects temperature instrumentation, guarantees its life-span.
Described mounting flange is taken over, at first adopt GB processing, in conjunction with the flange diameter of temperature instrumentation, the diameter of hot air duct, determine the size that mounting flange is taken over, process take-up gear on flange connecting pipe, both guaranteed that sealing also guarantees temperature tolerance, then a waterproof junction box is installed, by wire, the terminal box of temperature instrumentation is taken over outer terminal box with this flange and be connected, form globality sealing heatproof structure; In work, instrument brick and globality temperature instrumentation are integrated, and under the effect of High Temperature High Pressure hot blast, even produce displacement, the outside seal coupling device does not change, thereby form temperature instrumentation and the outside flexible structure that is connected.
The utility model has solved the defective that exists in the background technology.Have rational in infrastructure, safe and reliable, maintain easily and change, extend temperature instrumentation life-span, measure the advantages such as relatively accurate, be improvement and the innovation of blast funnace hot blast stove temperature detection.
