Technical field
The utility model relates to the material surface measurement instrument under a kind of high temperature, high pressure and the high dust condition, the radar stock rod that is used to measure charge level height in the State of Blast Furnace that especially a kind of adjustable angle is whole.
Background technology
In general, because the blast furnace top temperature is between 200～300 ℃, furnace inner gas pressure 0.25MPa, and contain a large amount of dust, in order to survey the furnace roof charge level, adopt the way of mechanical stock rod usually, promptly drag weight with direct current or alternating current generator, descend by control system control weight, when weight touches charge level, under the effect of control system, weight is descended with charge level, scrambler is measured the number of turns that weight rod tube is changeed, thereby records the true altitude of charge level.
But this measuring method has three shortcomings, the one, the control of motor is had relatively high expectations, so control circuit is complicated; The 2nd, in actual moving process, because the dislocation of scrambler often need be safeguarded complicated to " zero "; The 3rd, frequent carries chi and puts the chi operation, influences the serviceable life of equipment.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of radar stock rod that is used to measure charge level height in the State of Blast Furnace, by radar wave real-time detection charge level.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of radar stock rod that is used to measure charge level height in the State of Blast Furnace, form by radar sensor and angle adjuster; Angle adjuster is made up of lower flange, corrugated tube, reducer pipe, the upper flange that has the sensor installing port, adjustment screw rod, lower flange is connected the lower end of corrugated tube, reducer pipe is connected the upper end of corrugated tube, the other end of reducer pipe links to each other with upper flange, have the sensor installing port on the upper flange, being separated by 90 ° in the periphery of corrugated tube is provided with 4 groups of adjustment screw rods; Radar sensor is fixedly mounted in the upper flange by the sensor installing port.
Described radar sensor is the high temperature radar sensor.
Described corrugated tube and reducer pipe are metal material.
The material of described corrugated tube and reducer pipe is a kind of in stainless steel, galvanized sheet or the general steel plate.
The beneficial effects of the utility model are: adopt the radar stock rod, reduced the disposable money of establishing of equipment, be convenient to safeguard, long service life is measured accurately.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, 2, the radar stock rod that is used to measure charge level height in the State of Blast Furnace of the present utility model is made up of high temperature radar sensor 4 and angle adjuster 3; Angle adjuster 3 is made up of lower flange 31, corrugated tube 35, reducer pipe 36, the upper flange 33 that has sensor installing port 34, adjustment screw rod 32, the lower end of the corrugated tube 35 that lower flange 31 connects, reducer pipe 36 is connected the upper end of corrugated tube 35, the other end of reducer pipe 36 links to each other with upper flange 33, have sensor installing port 34 on the upper flange 33, being separated by 90 ° in the periphery of corrugated tube 35 is provided with 4 groups of adjustment screw rods 32; High temperature radar sensor 4 is fixedly mounted on the upper flange 33 by installing port 34.
Flange short tube 1 and the welded corner joint at 45 of blast furnace crust; Ball valve 2 be installed in flange short tube 1 directly over, with flange short tube 1 for standard flange connects, bolt; The angle adjuster 3 of radar stock rod be installed in ball valve 2 directly over, with ball valve 2 for standard flange connects, bolt.
Installation when waiting in the stove material loading, can be with material to debug.Debug process is: power on for high temperature radar sensor 4, observe the echo curve that radar detection is arrived, adjust screw rod 32 for 4 groups that adjust on the angle adjuster 3, thereby change the angle that transmits and receives of high temperature radar sensor 4, the echoed signal that sensor is detected reaches the strongest.
When echoed signal intensity during greater than the spurious echo signal, angular setting can be finished.At this moment, material level in the stove is promptly represented in the output of level-sensing device.
7 expressions is charge level among the figure, the 5th, and furnace top flange, the 6th, swivel chute.
The concise and to the point principle of work of the utility model radar stock rod is: constantly launch the frequency modulation continuous microwave by the high temperature radar sensor that is installed on the furnace roof top in stove, after microwave arrives charge level, turn back in the radar sensor again through the charge level reflection, because the speed of microwave is constant, so measure the time that is transmitted into reception, promptly know the distance H of detector to charge level.The signal processing apparatus signal of adjusting the distance carries out calculation process, converts distance signal to the controlling level signal, and carries out bar graph and numeral shows on display.
In order to measure charge level exactly, the microwave that requires radar detedtor to launch vertically acts on charge level, and this just need carry out the adjustment of angle to radar, and the utility model has designed the angle adjuster 3 that utilizes corrugated tube, by 4 groups of adjustment screw rods 32 of two ends welding, adjust the angle of radar sensor.
Described corrugated tube 35 is a metal material, can be stainless steel, galvanized sheet or general steel plate.
In sum, content of the present utility model is not limited in the above-described embodiment, knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the present utility model, but this embodiment is included within the scope of the present utility model.
