Description
Technical field
The utility model relates to blast furnace monitoring equipment, particularly the thermopair installed online of a kind of blast furnace hearth.
Background technology
At present in newly-built or overhauling reform, large blast furnace, follow the principle that efficient, longevity develops simultaneously, blast furnace generation stove labour is general all in 15 ~ 20 years for life, and the Aulomatizeted Detect indispensable technical measures that are prolonging campaign.Blast furnace hearth is blast fumance safety and the long-lived most important thing, and from current statistics, domestic and international blast furnace hearth burns the corner mostly occurring in sidewall or sidewall and furnace bottom, and what be commonly called as at once resembles pin attack sites.Therefore, cupola well bottom temperature on-line monitoring has become the important means of monitoring cupola well furnace bottom erosion state, is also set up cupola well bottom lining to corrode the necessary condition of mathematical model.
Blast furnace is when newly-built, furnace bottom and bosh gas index all bury the thermopair of some amount underground, but along with the passing of production and the severe environment of cupola well itself, a lot of thermopair all damages after using for some time and cannot change, this corrodes monitoring to brick lining in blast furnace chamber and production safety brings hidden danger.Along with the development of prolonging campaign technology, part producer is had to install thermopair additional at cupola well at present, to make up the monitoring blind area damaged thermopair and cause, but use common thermocouple, when post-grouting is installed, slurry effectively cannot fill up gap and the exhaust of perforate at thermocouple temperature sensitive head place, and this brings impact to accurate thermometric, heat conduction, is also an insurmountable equipment and technology difficult problem at present.
Summary of the invention
The purpose of this utility model is to design the thermopair that a kind of blast furnace hearth is installed online, can implement when blast furnace staying overhauls to install, can effectively, accurate measurements temperature of the furnace hearth, avoid common thermocouple that rear problem is installed online, the problem includes: grouting cannot effectively be vented and the problem of discontented opening gaps filled out by slurry.
For achieving the above object, the technical solution of the utility model is:
The thermopair that blast furnace hearth is installed online, it comprises, outer tube, and its one end is fixedly welded on shell of blast furnace, and the other end establishes flange plate; Outer tube tube wall establishes one exhaust/discharge pipe and corresponding control valve; Protective tube, State of Blast Furnace casing wall is stretched into until blast furnace hearth carbon brick layer and the ramming bed of material through described outer tube flange plate in its one end in outer tube, and this end end face establishes grout outlet; The protective tube the other end is positioned at outside flange plate, and closely the protective tube tube wall of establishing of this end establishes a grouting mouth; Two thermocouple wires, its one end to be stretched in protective tube from described protective tube outboard end and is stretched out protective tube end face to blast furnace hearth carbon brick layer; Terminal box, be arranged at described protective tube outboard end, the thermocouple wire the other end connects this terminal box.
Further, described protective tube grout outlet is arranged off-centre.
Again, described protective tube by nut locking in flange plate.
Preferably, the control valve on described exhaust/discharge pipe is ball valve.
The utility model thermocouple structure form is through the special electric thermo-couple that particular design manufactures, and outside protecting tube, have grouting mouth, grouting channel is located in protecting tube.
Thermopair, after blast furnace hearth opening or cleaning hole is installed, need, by carbon system material grouting treatment, contact closely knit to make thermopair with blast furnace hearth carbon brick and opening or cleaning interporal lacuna.
Thermopair grouting channel is designed to duct type, avoids grouting to there is air gap and dead angle, improves measurement accuracy.
Open exhaust valve, grouting material passes through grouting mouth pressing-in grouting passage, from protecting tube end grout outlet out; after space, thermopair end is filled up by carbon system grouting material, then return away to stove skin from the gap in opening or cleaning hole, finally emerge from the valve of vapor pipe; stop pressure, close valve.
The beneficial effects of the utility model:
1. the utility model can after the original design thermocouple break of blast furnace, and when blast furnace regular damping down maintenance, on-line implement is installed, and can have efficient recovery to the monitoring of cupola well.Meanwhile, blast furnace being needed to the producer strengthening cupola well carbon brick erosion monitored density or do erosion models, is all a kind of only selection.
2. the utility model is reasonable in design, install save time, laborsaving, practical, accurate, efficient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
See Fig. 1, the thermopair that a kind of blast furnace hearth of the present utility model is installed online, it comprises, outer tube 1, and its one end is fixedly welded on shell of blast furnace 105, and the other end establishes flange plate 2; Outer tube 1 tube wall establishes one exhaust/discharge pipe 3 and corresponding control valve 4; Protective tube 5, its one end in outer tube 1, stretches into State of Blast Furnace casing wall 100 through described outer tube 1 flange plate 2 until blast furnace hearth carbon brick layer 101 and the ramming bed of material 102 (in State of Blast Furnace casing wall 100, other are cooling stave 103, packing layer 104 and stove skin 105), and this end end face establishes grout outlet 51; Protective tube 5 the other end is positioned at outside flange plate 2, and closely protective tube 5 tube wall of establishing of this end establishes a grouting mouth 52; Two thermocouple wires 6,6 ', its one end to be stretched in protective tube 5 from described protective tube 5 outboard end and is stretched out protective tube 5 end face to blast furnace hearth carbon brick layer 101; Terminal box 7, is arranged at described protective tube 5 outboard end, and thermocouple wire 6, the 6 ' the other end connects this terminal box 7.
