[0023] A blast furnace slag viscosity detection device capable of judging the liquid level height according to the present utility model includes a base 1, a rotating plate 2, a rotating assembly, a frame 11, a second motor 13, a lead screw 14, a torque sensor 17, a fixed plate 18, a corundum measuring tube 21 and a molybdenum probe head 22; the specific structure is as Figure 1 、 Figure 2As shown in the figure, the rotating plate 2 is a horizontally arranged circular structure, and is horizontally and parallelly arranged at intervals on the upper surface of the horizontally arranged base 1, and is horizontally and rotationally connected to the base 1 through a rotating assembly; in the middle position of the upper surface of the rotating plate 2, there is also a hollow cuboid-shaped frame 11 with an open left side vertically arranged, and in the upper position inside the frame 11, there is also a partition 12 horizontally arranged to match it, and the frame 11 is divided into two parts up and down by the partition 12; in the middle position inside the frame 11, there is also a lead screw 14 vertically arranged, the lower end of the lead screw 14 is rotationally connected to the inner bottom surface of the frame 11, and its upper end vertically passes through the partition 12 and the upper surface of the frame 11 in sequence, and is linked to the output end of the second motor 13; on the lead screw 14, relative to the area directly above the partition 12, there is also a torque sensor 17, and in the area directly below the partition 12 inside the frame 11 and on the left and right sides of the lead screw 14, there are two vertically symmetrically arranged guide rails 15, the upper ends of each guide rail 15 are respectively screwed and fixed to the corresponding positions on the lower surface of the partition 12, and the lower ends of each are respectively screwed and fixed to the corresponding positions on the inner bottom surface of the frame 11; on the lead screw 14, relative to the area directly below the partition 12, there is also a slider 16 sleeved and screwed, and the slider 16 is vertically and slidably connected to the two guide rails 15, and thus, driven by the second motor 13, the slider 16 moves vertically up and down along the lead screw 14, and the rotational force of the lead screw 14 is monitored by the torque sensor 17; among them, the left side surface of the slider 16 horizontally and perpendicularly extends out of the left side surface of the frame 11, and it is ensured that the vertical up and down movement of the frame 11 does not interfere with the slider 16.

[0024] On the left side surface of the slider 16 of the present utility model, there is also a fixing plate 18 horizontally arranged, as Figure 1 , Figure 2 shown, the left end of the fixing plate 18 horizontally and perpendicularly extends out of the left side surface of the frame 11, and between the upper and lower surfaces of the fixing plate 18 near its right end position and the left side surface of the slider 16, there is also a reinforcing plate 19 vertically arranged, and the fixing plate 18 is fixed and strengthened by the reinforcing plate 19; on the left end of the lower surface of the fixing plate 18, there is also a corundum measuring tube 21 vertically arranged, and at the lower end of the corundum measuring tube 21, there is also a molybdenum measuring head 22 coaxially arranged, and thus the molybdenum measuring head 22 is inserted downward into the blast furnace 24 through the graphite cover of the blast furnace 24 and descends with the slider 16 below the liquid level to detect the viscosity of the slag in the blast furnace 24.

Fixed columns 5 are vertically and symmetrically provided at four right angles of the lower surface of the base 1, and each fixed column 5 is arranged within the square area surrounded by the four universal wheels 4. Among them, when in the upper limit position, the lower end surface of each universal wheel 4 is located above the horizontal plane where the lower end of the corresponding fixed column 5 is located. Under the drive of the hydraulic cylinder 3 of the present utility model, through the cooperation of the universal wheel 4 and the fixed column 5, the switching between the moving state and the detection state is carried out.

[0027] The rotating assembly of the present utility model is arranged without interference with the four hydraulic cylinders 3, and the rotating assembly includes a side plate 6, a rotating shaft 7, a main bevel gear 8, a driven bevel gear 9, and a first motor 10. As Figure 1 、 Figure 2 shown, a rotating shaft 7 is also vertically provided at the middle position inside the base 1.

The several circles of roller sets 25 are coaxially arranged with the rotating plate 2 and are respectively arranged without interference with the rotating shaft 7. Each roller set 25 is conical, with its small end near the rotating shaft 7 and its large end at the other end, so as to adapt to the smaller linear velocity near the rotating shaft 7 when the rotating plate 2 rotates.

[0029] The working principle of the present utility model is as follows: First, with the assistance of a person, the device is moved to a position close to the blast furnace 24 through the universal wheels 4; then, the piston rod of the hydraulic cylinder 3 retracts, driving the universal wheels 4 to lift, so that the fixed column 5 contacts the ground to ensure the stability of the detection state; then, under the drive of the rotating assembly, it is ensured that the molybdenum probe 22 is coaxially arranged with the graphite cover of the blast furnace 24; then, the molybdenum probe 22 descends with the slider 16 and penetrates downward into the blast furnace 24 through the graphite cover of the blast furnace 24. At this time, the molybdenum probe 22 is in the air, and the rotational force of the lead screw 14 is constant; when the molybdenum probe 22 contacts the slag liquid level, due to the viscosity of the slag liquid level, a greater force is required for the lead screw 14 to rotate. At this time, the torque sensor 17 detects a sudden change in torque, and it can be judged that the molybdenum probe 22 has descended to the liquid level; at this time, descending another 3 cm is the detection position, and the viscosity of the slag in the blast furnace 24 can be detected through the molybdenum probe 22;

[0030] The infrared distance sensor 20 detects the distance between the fixed plate 18 and the blast furnace 24, and forms a displacement curve with the historical experimental data on the mini-computer 23, so as to judge the wear condition at the bottom of the blast furnace 24.

[0031] The beneficial effects of the present utility model are as follows:

[0032] (1) By the combined use of the lead screw 14 and the torque sensor 17 in the present utility model, it is convenient to judge whether the molybdenum probe 22 contacts the liquid level according to whether the rotational force of the lead screw 14 changes, so as to judge the liquid level height, which is time-saving, labor-saving and safe, and improves the accuracy of the detection result of the slag viscosity;

[0033] (2) By setting the infrared distance sensor 20 in the present utility model, the wear condition at the bottom of the blast furnace 24 can be judged according to the distance between the fixed plate 18 and the blast furnace 24;

[0034] (3) Through the combined use of the hydraulic cylinder 3, the universal wheels 4 and the fixed column 5 in the utility model, it is convenient to switch between the moving state and the detection state, which not only ensures the stability during detection, but also can be applied to the detection of the slag viscosity of different blast furnaces 24, and has a wide application range;
