[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

[0026] This utility model provides an online automatic slag skimming and detection device for melt, which automatically enters the furnace or slag bag to skim off the floating slag and oxide layer on the surface of the high-temperature melt in the detection area, exposes the high-temperature melt body, discharges oxygen in the detection area, prevents the high-temperature melt from being oxidized, and detects and analyzes the elemental composition content of the melt.

[0027] like Figure 1 As shown, an automatic slag skimming online detection device for melt 10 includes a cylinder 1, a lifting mechanism 2, a slag skimming plate 3, a rotating shaft 4, a drive module 5, and a melt composition detector.

[0028] The bottom of the cylinder 1 is provided with a melt inlet 6. When the high-temperature melt 10 enters the bottom of the cylinder 1, the melt 10 will enter the cylinder 1 from the melt inlet 6 to form the detection area 7.

[0029] A laser inlet 8 is provided at the top of the cylinder 1. The melt composition analyzer is used to emit a detection laser 9. The detection laser 9 enters from the laser inlet 8 and performs elemental composition detection on the melt 10 in the detection area 7.

[0030] One side of the outer wall of the cylinder 1 is fixedly connected to the lifting mechanism 2. The lifting mechanism 2 is used to drive the bottom of the cylinder 1 to enter or leave the melt 10. During the test, the lifting mechanism 2 determines that the bottom of the cylinder 1 has entered the high-temperature melt 10 in the furnace or slag bag. After the test is completed, the cylinder 1 is lifted to leave the furnace or slag bag. The lifting mechanism 2 can be pneumatic, electric or robotic.

[0031] The other side of the cylinder 1 has an opening, and a skimming plate 3 is set at the opening. The rotating shaft 4 is fixedly connected to the skimming plate 3. The two ends of the rotating shaft 4 are rotatably connected to the side wall of the cylinder 1. The way the rotating shaft 4 is rotatably connected to the side wall of the cylinder 1 can be selected as needed. For example, through holes are provided on the two opposite side walls of the cylinder 1, and the two ends of the rotating shaft 4 are rotatably connected to the through holes. For example, bearings are fixed on the two opposite side walls of the cylinder 1, and the two ends of the rotating shaft 4 are respectively supported on the inner ring of the bearing.

[0032] The drive module 5 is fixedly installed above the cylinder 1. The drive module 5 is connected to the rotating shaft 4 for transmission. The drive module 5 is used to drive the rotating shaft 4 to rotate, thereby driving the skimming plate 3 to rotate and remove the air in the cylinder 1. At the same time, it scrapes the surface scum of the detection area 7 to the outside of the melt inlet 6.

[0033] For example, the skimming plate 3 and the cylinder 1 are made of ceramic, which can withstand the erosion of the high-temperature melt 10 and does not react with the melt 10, making it less prone to material sticking.

[0034] like Figure 2 As shown, for example, the cross-section of the cylinder 1 is semi-circular, the rotating shaft 4 is located in the middle of the skimming plate 3, and the two ends of the rotating shaft 4 are rotatably connected to the middle of the side wall of the cylinder 1. The length of the skimming plate 3 is less than the diameter of the semi-circular cross-section of the cylinder 1.

[0035] like Figure 1 As shown, for example, the automatic slag skimming online detection device for melt 10 also includes a base 11 and a transfer plate 12, wherein one side of the outer wall of the cylinder 1 is fixedly connected to the transfer plate 12 through the base 11, and the transfer plate 12 is connected to the lifting mechanism 2.

[0036] like Figure 2 As shown, a connecting plate 13 is provided at the bottom of the drive module 5. One side of the connecting plate 13 is fixedly connected to the base 11, and the other side of the connecting plate 13 is fixedly connected to the top of the cylinder 1. For example, the adapter plate 12 is made of metal.

[0037] like Figure 1 As shown, for example, the lifting mechanism 2 includes a slider 14, a guide rail 15, and a lead screw 16. The adapter plate 12 is fixedly connected to one side of the slider 14, the slider 14 is slidably connected to the guide rail 15, and the lead screw 16 is threadedly connected to the slider 14. The rotation of the lead screw 16 drives the slider 14 to move linearly along the guide rail 15 to achieve the lifting function.

[0038] For example, the drive module 5 is a rotational power unit, which can be a motor or a rotary cylinder. For example, a first gear 17 is fixedly installed at one end of the rotating shaft 4 that passes through the cylinder 1, and a second gear 18 is fixedly installed at the output end of the drive module 5. The second gear 18 is connected to the first gear 17 through a toothed belt 19. The drive module 5 and the rotating shaft 4 are driven by the gear and the toothed belt 19, so that the transmission is smooth.

[0039] The second gear 18 of the drive module 5 drives the first gear 17 to rotate via the toothed belt 19, thereby driving the skimming plate 3 to rotate 180 degrees counterclockwise around the rotating shaft 4, expelling the air inside the cylinder 1, and scraping the surface scum of the detection area 7 at the bottom of the cylinder 1 to the outside of the melt inlet 6.

[0040] like Figure 2 As shown, for example, the automatic slag skimming online detection device for melt 10 also includes a protective gas inlet pipe 20. A gas inlet is provided on the side wall of the cylinder 1 near the base 11. The protective gas inlet pipe 20 is fixedly connected to the base 11. One end of the protective gas inlet pipe 20 is connected to the gas inlet of the cylinder 1, and the other end of the protective gas inlet pipe 20 is connected to a gas source, for example, the gas source can be argon.

[0041] like Figure 2 As shown, for example, the protective gas inlet pipe 20 includes a straight pipe section 21 and an inclined pipe section 22. The straight pipe section 21 is fixedly connected to the base 11. One end of the straight pipe section 21 is connected to the gas source, and the other end of the straight pipe section 21 is connected to the gas inlet of the cylinder 1 through the inclined pipe section 22. The inclined pipe section 22 has an angle with the liquid surface of the melt 10 in the detection area 7, which enables the protective gas to be blown into the melt 10 in the detection area 7.

[0042] For example, the protective gas inlet pipe 20 is made of metal and contains argon protective gas. The density of argon is greater than that of air to protect the melt 10 in the detection area 7.

[0043] like Figure 1 and Figure 2 As shown, for example, the automatic slag skimming online detection device for melt 10 also includes a temperature sensor 23, which is fixedly installed at the bottom of the adapter plate 12. For example, the temperature sensor 23 can be a thermocouple. The temperature sensor 23 is used to obtain the temperature change of melt 10. The detection device controls the depth of the cylinder 1 into melt 10 according to the temperature change of melt 10.

[0044] The working principle of this utility model's automatic slag skimming online detection device for melt 10 is as follows:

[0045] At the beginning, the lifting mechanism 2 is activated and pushes the cylinder 1 downward along a predetermined trajectory to invade the high-temperature melt 10 located in the furnace or slag bag. When the melt inlet 6 of the cylinder 1 invades the high-temperature melt 10, the high-temperature melt 10 and the slag on the upper surface enter the cylinder 1 from the melt inlet 6.

[0046] When the temperature sensor 23 comes into contact with the high-temperature melt 10, it measures and records the temperature of the high-temperature melt 10; at the same time, because the relative height between the temperature sensor 23 and the melt inlet 6 is fixed, the thermocouple measures the temperature data of the melt 10, that is, when the cylinder 1 penetrates the high-temperature melt 10 to a predetermined depth, the lifting mechanism 2 stops operating.

[0047] The drive module 5 starts and drives the skimming plate 3 to rotate 180 degrees counterclockwise around the rotating shaft 4, scraping out the high-temperature melt 10 and scum that have entered the cylinder 1, allowing the high-temperature melt 10 located below the scum layer to re-enter the cylinder 1; at the same time, the skimming plate 3 closes the cylinder 1; because at this time the melt inlet 6 is located in the melt 10 below the scum layer, there is no scum in the melt 10 material entering from the melt inlet 6, nor is it oxidized by air.

[0048] At this time, argon gas is blown into the surface of the melt 10 in the detection area 7 through the protective gas inlet pipe 20. Since the density of argon gas is greater than that of air, the air is discharged from the laser inlet 8, and the melt 10 in the detection area 7 is isolated from the air. At this time, the detection laser 9 emitted by the melt composition detector is injected from the laser inlet 8 to detect the elemental composition of the melt 10 in the detection area 7. After the detection is completed, the protective gas inlet pipe 20 stops supplying argon gas, and the lifting mechanism 2 lifts the cylinder 1 away from the furnace or slag bag, and the operation is completed.

[0049] When testing the composition of melt 10, the detection device of this invention can scrape off the slag on the surface of melt 10 by rotating the skimming plate 3, and form a sealed cavity with the cylinder 1 to prevent external slag and air from entering, thereby improving the accuracy of the test. When testing the composition of melt 10, the detection device of this invention can also remove oxygen from the cylinder 1 by rotating the skimming plate 3, protecting the melt 10 to be tested from oxidation.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
