Technical field
A kind of device that leakage detection is carried out to blast furnace tuyere small sleeve is the utility model is related to, belongs to blast furnace maintenance tool technique neck
Domain.
Background technology
Blast furnace tuyere small sleeve is the visual plant in blast furnace air inlet system, and its effect is that hot blast is sent into blast furnace.Wind
The working environment of mouthful small set is extremely severe, and the front end of tuyere small sleeve is nearly 2000 DEG C of hot environment, slag iron melt temperature 1400
More than DEG C.Tuyere small sleeve uses copper material, and internal water flowing cooling, the front end of tuyere small sleeve is extend into stove, avoid hot blast and
Coal dust directly washes away furnace wall.Water leakage fault can occur in use for tuyere small sleeve, and the method for current tuyere small sleeve leakage detection mainly has：
Water temperature difference method, direct observational method.
Water temperature difference method：The difference of leaving water temperature and inflow temperature is measured, typically watertight tuyere small sleeve, water temperature difference is small
In 10 DEG C, if after leak, water yield is reduced, leaving water temperature can raise, and cause water temperature difference to raise, therefore can be used for judging air port
It is small set whether leak.
Direct observational method：From blowpipe peep-hole（Small cover glass）See, air port dross, steam, flame jaundice or obfuscation, wind
Mouthful small set and middle inner room string water, can be used for judging tuyere small sleeve whether leak.
Above two method has the following disadvantages in the work of cooling wall leakage detection：First, when water leakage is big, both sides
Method may determine that water leakage situation, and when water leakage is smaller, water temperature difference change is tiny, drainage unobvious, can not accurately sentence
It is disconnected；Secondly, even if finding drainage by water temperature difference method or direct observational method, it is also difficult to judge leakage point, can not be to leak
Point is positioned, therefore, it is difficult to formulate processing and solution, so that have impact on being smoothed out for production.
In view of there is deficiency, therefore can not be rapidly and accurately above in the detection blast furnace tuyere small sleeve leak method used at present
The water leakage fault of tuyere small sleeve is found, the problem of being accordingly difficult to effectively handle tuyere small sleeve leak, is unfavorable for blast fumance, ten
Dividing is necessary to be improved existing blast furnace tuyere small sleeve leak method.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of dress that accurate leakage detection is carried out to blast furnace tuyere small sleeve
Put, this leak detection device accurately can whether there is water leakage fault by the small set of detection air port, and manufacturing cost is cheap, operation letter
List, detection speed are fast, safe, have very strong practicality.
Solve above-mentioned technical problem technical scheme be：
A kind of device that accurate leakage detection is carried out to blast furnace tuyere small sleeve, it include water inlet pipe clamping head front connector, it is preceding to silk,
Drain valve, water inlet pipe clamping head rear connectors, after to silk, water inlet pipe clamping head front connector is by preceding to silk and the water inlet pipe clamp unsnaped
One end of head is connected, and water inlet pipe clamping head rear connectors are connected by rear to silk with the other end for the water inlet pipe clamping head unsnaped,
Drain valve is installed between water inlet pipe clamping head front connector and water inlet pipe clamping head rear connectors.
The above-mentioned device that accurate leakage detection is carried out to blast furnace tuyere small sleeve, the axis of the drain valve screen pack and water inlet pipe
Axis has slanted angle, and slanted angle is 45 °.
The above-mentioned device that accurate leakage detection is carried out to blast furnace tuyere small sleeve, it also has potassium permanganate reagent bottle, potassium permanganate examination
Agent bottle is placed in drain valve, and potassium permanganate powder is filled in potassium permanganate reagent bottle, is had on the body of potassium permanganate reagent bottle
Body opening.
It is of the present utility model to be beneficial in that：
Tuyere small sleeve leak detection device of the present utility model is dissolved in the characteristic of water discoloration using potassium permanganate, can be from water seepage
Color change determine the small set of leak, leakage detection visual result and it is accurate.Tuyere small sleeve leak detection device structure of the present utility model
It is simple and convenient to operate, detects rapid, testing result accurately and reliably, while makes easily, it is cheap.
Tuyere small sleeve leakage inspection method of the present utility model can make blast furnace staff to the rapid leakage detection of blast furnace tuyere small sleeve
Corresponding control measure can be taken.
The utility model is pioneering in blast furnace tuyere small sleeve Technology of Leak-checking by Gas, not only with simple detection means and method solution
Determined it is long-term do not solved effectively the problem of judging whether leak, also overcome and be difficult to accurately cover leakage in the prior art
The problem of positioning, there is very positive practical function to production, be worth popularization and application in industry.
