Description
Technical field
The present invention relates to a kind of detection device, especially a kind of blast-furnace hot-air pipeline anti-string wind anti-clogging detection device.
Background technology
At present, during blast furnace ironmaking produces, needing to be transmitted the hot blast of about more than 1300 degree Celsius of 0.4 MPa by hot air duct, hot air duct, for can bear HTHP, typically uses the structure of outside steel pipe internal refractory bricking.In order to measure the pressure in hot air duct, needing to take pressure port at fire-brick lined, simultaneously in outside steel pipe perforate and weld pressure pipe, so, the pressure obtained in hot air duct by pressure pipe is completed the measurement of pressure in blast-furnace hot-air pipeline；Same method is taked to complete the measurement of temperature in hot air duct.In prior art, during fire-resistant brick hole excessive because building reason usually perforate by laying bricks or stones, the 15mm required much larger than pressure detecting, used after a period of time, due to internal refractory bricking deform, subside, the reason such as come off, gap can be produced between bricking and outside steel pipe, wind in gap can enter in pressure pipe, namely " string wind " phenomenon, not only makes hot-blast pressure, temperature detection produce fault, serious blast furnace can only be made to be forced damping down grouting, and be in the milk that to be likely to cause pressure port completely plugged.This is the weak point existing for prior art.
Summary of the invention
The technical problem to be solved, it is aiming at the deficiency existing for prior art, and the technical scheme of a kind of blast-furnace hot-air pipeline anti-string wind anti-clogging detection device is provided, the program is provided with inner and outer tubes, in the cavity that the inwall of outer tube and the outer wall of the outer wall of inner tube, firebrick lining are formed, it is filled with sealing medium, thus avoids the string wind and the problem of blocking produced when the physical parameter to blast-furnace hot-air pipeline detects.
This programme is achieved by the following technical measures: a kind of blast-furnace hot-air pipeline anti-string wind anti-clogging detection device, including the outer tube being fixed on the shell of hot air duct and be connected with shell, also include the inner tube being fixed on outer tube, the lower end of this inner tube is positioned at the embedded hole of the firebrick lining of hot air duct, is filled with sealing medium in the cavity that the outer wall of the inwall of described outer tube, the outer wall of inner tube and firebrick lining is formed.
Further improvement of the present invention also has, the top of described outer tube is fixed with top cover, said inner tube is through this top cover and fixing with top cover is connected, top cover acts on jointly with refractory cement, air leakage phenomena can be avoided completely, avoid the convection current of the high temperature air in hot air duct and air, further enhancing the sealing property of detection device.
Further improvement of the present invention also has, the bottom surface of said inner tube is higher than the lower limb 180-220mm of embedded hole, if the bottom surface of inner tube is less than the lower limb of embedded hole, then can damage because the high-temperature baking in hot air duct makes inner tube lower end produce, melting phenomenon is produced time serious, if the bottom surface of inner tube is higher than the lower limb of embedded hole more than 220mm, then inner tube cannot obtain the physical parameter in hot air duct accurately, cause measuring inaccurate, obtaining through test of many times, the bottom surface of inner tube is most preferred higher than the lower limb 200mm of embedded hole.
Further improvement of the present invention also has, and the axis of the axis of described outer tube, the axis of inner tube and top cover, on same straight line, facilitates the installation to outer tube, inner tube and top cover and fixes.
Further improvement of the present invention also has, and said inner tube is fixed by its at least three outside support bars, and described support bar is positioned at described sealing medium.
Further improvement of the present invention also has, described support bar has the angle between four and adjacent two support bars to be 90 °, support bar not only acts as the effect of fixing inner tube, after cast refractory cement, inner tube, outer tube, refractory cement are integrally formed, support bar plays the effect of skeletal support in refractory cement, adds the intensity of refractory cement.
Because the temperature in hot air duct is up to more than 1000 degree Celsius, high temperature resistant, the refractory cement of good seal performance that described sealing medium uses.
Further improvement of the present invention also has, and the upper end of said inner tube is connected with stop valve by pipe nipple, and this stop valve is connected with pressure transmitter, the pressure measxurement in hot air duct.
Further improvement of the present invention also has, and the upper end of said inner tube is connected with detector unit, the temperature survey in hot air duct.
The beneficial effect of this programme can be learnt according to the narration of such scheme, the present invention includes the outer tube being fixed on the shell of hot air duct and being connected with shell, also include the inner tube being fixed on outer tube, the lower end of this inner tube is positioned at the embedded hole of the firebrick lining of hot air duct, is filled with sealing medium in the cavity that the outer wall of the inwall of described outer tube, the outer wall of inner tube and firebrick lining is formed.The present invention is utilized to obtain the physical parameter in hot air duct, processing ease, it is only necessary to temperature or pressure-detecting device to be connected with inner tube；The use of sealing medium can effectively guarantee between the outer wall of the outer wall of the shell of hot air duct, outer tube and firebrick lining, inner tube very close to each other, stop the problem of subsiding of firebrick lining, avoid the string wind problem at a new generation's stove labour hot air duct, decrease because string wind the problem of blockage in after the grouting that produces, ensure being smoothed out of physical parameters measurement in hot air duct；Present configuration is simple simultaneously, it is simple to maintenance maintenance.As can be seen here, the present invention compared with prior art, has prominent substantive distinguishing features and significantly progress, and its beneficial effect implemented also is apparent from.
