Description
Technical field
The utility model relates to a kind of non-contact infrared thermometry device.
Background technology
As long as utilize blast furnace ironmaking can grasp timely and accurately its interior molten iron temperature, just can control sufficient and stable furnace temperature, to guarantee the blast furnace stable smooth operation; Simultaneously, guaranteeing to reduce silicone content and the coke ratio of molten iron under the enough prerequisites of molten iron physical temperature; In addition, the height of molten iron temperature not only affects the inner quality of foundry goods, and also with its pore, slag inclusion and surface imperfection are contacted directly, and for this reason, detecting molten iron temperature is an important means of smelting procedure.
In the prior art, generally adopt the blast-melted discontinuous thermometric that carries out of the quick minisize thermoelectric couple of deflection type, and be the artificial thermometric of discontinuous, its mode of operation is that the operator is fast measuring molten iron temperature in the disposable thermal galvanic couple insertion molten iron, when the digital display alarm instrument sends guard signal, thermometric finishes, and simultaneously the temperature parameter of measuring is uploaded to computer control system.This shows that this its measuring process of thermometric mode is discontinuous, temperature measurement signal is interrupted, and the operator need stand in the iron runner limit and temperature thermocouple is inserted finish measurement in the molten iron, and its measuring process is dangerous, has great potential safety hazard; In addition, in measurement procedure, the compensating lead wire that every temperature-measuring gun rear dragging is about 10 meters is connected with the digital display alarm instrument, temperature-measuring gun and compensating lead wire airduct, the water pipe weave in of temperature-measuring gun and stokehold often occur, and the measure field noise are larger because temperature is high and fragile, slightly do not note can't hear heat alarm, also need remeasure after missing Measuring Time, cause measurement untimely, bring great inconvenience to operation simultaneously; Take off data is not accurate enough; Temperature element and materials consumption are larger, thermometric cost and failure rate all higher, maintenance is very large.
Summary of the invention
Task of the present utility model provides a kind of mode of utilizing non-contact infrared thermometry, and to solve take off data inaccurate and the temperature element consume is large and the problem such as operation inconvenience is measured the associated plant of molten iron temperatures in the blast furnaces.
The associated plant of molten iron temperature comprises infrared thermometer and the projector that is electrically connected with Infrared survey instrument output terminal in the detection blast furnace that the utility model proposes, and the receptor that be used for to receive the electrical signal that projector sends, the output terminal of this receptor is electrically connected with the computer input end.
The temperature-measuring range 700-1800 of described infrared thermometer ℃.Also be provided with data acquisition unit between described receiving apparatus and the computer.
The utility model proposes to detect the associated plant employing infrared thermometer detection molten iron temperature of molten iron temperature in the blast furnace, and operation is very easy for it, and the data of molten iron temperature are very accurate in the measurement blast furnace; Simultaneously real can the detection signal of Infrared survey instrument is wireless the time because of projector, be transferred to receptor exactly, to be transferred to computer again by receptor, and computer carries out can be formed directly in readable documents and linear graph behind the software analysis, is conducive to temperature signal and reads and on-the site analysis and storage.
Description of drawings:
Accompanying drawing 1 is the functional block diagram of an embodiment of associated plant of molten iron temperature in the detection blast furnace that proposes of the utility model.
Embodiment:
Referring to Fig. 1, this figure provides the functional block diagram of an embodiment of associated plant of molten iron temperature in the detection blast furnace that the utility model proposes.This device comprises infrared thermometer 1 and the projector 2 that is electrically connected with the output terminal of Infrared survey instrument 1, and the receptor 3 that be used for to receive the electrical signal that projector 2 sends, the output terminal of this receptor 3 is electrically connected with computer 4 input terminuss, and also is provided with data acquisition unit 5 between receiving apparatus 3 and computer 4.Wherein, the temperature-measuring range of infrared thermometer 1 is set to 700-1800 ℃.Between infrared thermometer 1 and projector 2, adapter 6 is set also.
When the molten iron temperature that detects with this associated plant in the blast furnace, at first use molten iron in the infrared thermometer 1 field measurement blast furnace, the temperature signal that detects is shown on the spot, by adapter 6 temperature signal is exported to projector 2 simultaneously, emission machine 2 is converted into the electrical signal of standard with temperature signal, makes it be modulated to radiowave Stochastic Modulation transmitted at high speed.Receiving apparatus 3 carries out digital collection to original signal after receiving end is received temperature signal, enter computer 4 and carry out software analysis, directly forms readable documents, forms form and linear graph, is used for temperature signal and reads and on-the site analysis and storage.
Claims (3)
1. the associated plant of molten iron temperature in the detection blast furnace, it is characterized in that: this associated plant comprises infrared thermometer and the projector that is electrically connected with Infrared survey instrument output terminal, and the receptor that be used for to receive the electrical signal that projector sends, the output terminal of this receptor is electrically connected with the computer input end.
2. associated plant according to claim 1 is characterized in that: the temperature-measuring range 700-1800 of described infrared thermometer ℃.
