The non-contact infrared thermometer has many defects in regular inspection. Firstly, a furnace body is attached with a lot of dust and other media, the non-contact measurement error is too large, and the temperature change condition of a furnace shell cannot be truly reflected; secondly, the blast furnace has a plurality of measuring dead angles, and the manual work is difficult to reach; thirdly, the inspection measurement frequency is low, and the comparison cannot be carried out in real time; in addition, the manual measurement mode has high labor intensity and certain potential safety hazard.
CN 201220370598.X discloses a wireless blast furnace shell temperature measuring device, which can solve some problems existing in the regular routing inspection of the existing non-contact infrared thermometer, but still has the following defects: 1. the sensor transmission signal is an analog signal, temperature compensation is carried out by a compensation wire, and a large temperature drift can be formed in winter and summer, so that the measurement precision is reduced; 2. the wireless transmitter has insufficient radio frequency gain and insufficient barrier crossing capability, so that the transmission distance is smaller and smaller, and the signal transmission is unstable after long use; 3. the number of the wireless acquisition devices connected with the sensors is less than 20, the one-time investment cost is too high, and the online expansibility is poor; 4. the data can be displayed only by a single upper computer, and no touch screen is arranged on the spot to display a data curve and give an alarm on the spot in real time.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a be applied to the wireless temperature measuring device of stove skin of iron-making blast furnace, can gather the stove skin temperature on line in real time.
The utility model provides a technical scheme that its technical problem adopted is:
a wireless temperature measuring device for a furnace shell of an iron-making blast furnace comprises a strong magnetic temperature sensor, a wireless data transmitter and a data collector, wherein the strong magnetic temperature sensor is packaged by a stainless steel blind pipe and is adsorbed on the blast furnace shell through strong magnetism; the wireless data transmitter transmits signals to a data collector arranged at the front platform of the furnace, the data collector is provided with a liquid crystal touch screen, displays a furnace skin temperature data curve in real time and alarms on site in real time, and can also display alarms on an upper computer system.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, beneficial effect is:
firstly, the problem that the non-contact infrared thermometer has too large measurement error and cannot truly reflect the temperature change condition of the furnace shell is solved, and the non-contact infrared thermometer can directly contact the furnace shell through a strong magnetic sensor and can accurately measure the temperature and reflect the temperature change of the furnace shell; secondly, the defect that the temperature cannot be acquired in real time due to the fact that a non-contact infrared thermometer is used for regular inspection is overcome, and the temperature of the furnace shell can be acquired in real time on line; and thirdly, the problems of short transmission distance, poor obstacle crossing capability, large precision drift in winter and summer, single display alarm, poor expansibility and the like of other wireless furnace shell temperature measurement products are solved.
Further, the utility model discloses preferred scheme is:
the data acquisition unit transmits data to the upper computer system through a 485 bus and transmits the data to the mobile phone terminal through the internet. And the data is sent to an upper computer, so that temperature display, real-time historical curve display and storage, on-site alarm and alarm historical record can be realized.
