Technical Field
[0001] This utility model relates to blast furnace monitoring technology, and in particular to a blast furnace leakage early warning device. Background Technology
[0002] The blast furnace is an important auxiliary equipment in steelmaking that regulates and balances the supply and demand of molten iron between the blast furnace and the converter. It can ensure an uninterrupted supply of molten iron needed by the converter. It is generally constructed with refractory bricks or integrally cast loose refractory materials. During the use of the blast furnace, it is prone to leakage accidents due to chemical erosion by high-temperature slag, mechanical damage from molten iron scouring, and thermal stress spalling caused by drastic temperature changes in the furnace lining refractory material.
[0003] To prevent blast furnace leakage accidents, the current common method for monitoring the corrosion of the furnace lining refractory material is to manually measure the temperature of the furnace shell using a portable handheld thermometer or a thermal imager. However, this monitoring method has limitations, including the inability to continuously monitor temperature changes, limited early warning capabilities, and high labor intensity for operators due to frequent temperature measurements. Therefore, this invention proposes a blast furnace leakage early warning device that is easy to install at a location that can be selected based on the site environment, does not affect the production process, and ensures personnel safety to meet the current needs.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.
[0017] like Figures 1 to 3In the embodiment of the blast furnace leakage warning device of this utility model shown, the blast furnace leakage warning device includes an infrared thermal imager body 1 and a concave placement frame 2. The infrared thermal imager body 1 is detachably mounted on the placement frame 2. Clamping members 3 are slidably connected to both sides of the placement frame 2, and the opposite sides of the two clamping members 3 abut against the two sides of the infrared thermal imager body 1. A branch pipe 4 is threaded to the bottom of the placement frame 2. A slidable support rod 5 is provided inside the branch pipe 4. A support 6 is fixed to the bottom of the support rod 5. A plurality of clearance grooves arranged in a circular array are opened at the bottom of the support 6. A support leg 7 is hinged to the clearance groove via a rotating shaft. The upper side of the support leg 7 can contact the top of the corresponding clearance groove. Rotatable rotating columns 8 are provided on both sides of the placement frame 2. A concave mounting bracket 9 is fixed to one side of each of the two rotating columns 8. The device can be adjusted according to the environment near the blast furnace. A suitable installation point can be chosen. Depending on the location, the device can be installed at a certain height using the mounting bracket 9, or supported on the ground using the legs 7. When the device is installed on a wall or other external structure using the mounting bracket 9, the placement frame 2 can be rotated using the rotating column 8, thus facilitating the adjustment of the angle of the infrared thermal imager body 1. This allows for easy adjustment of the device according to actual needs. When the device needs to be installed on the ground, the height of the infrared thermal imager body 1 can be adjusted by spreading out the multiple legs 7 and adjusting the height of the support rod 5 within the support pipe 4. This facilitates the use of the device and avoids the need for operators to use portable thermometers or thermal imagers to measure the temperature of the blast furnace shell. It enables continuous monitoring of temperature changes, providing a good early warning function without affecting the production process and ensuring personnel safety.
[0018] In one embodiment of this application, preferably, a baffle 10 is fixed to the front side of the placement frame 2, which serves to further limit the infrared thermal imager body 1.
[0019] In one embodiment of this application, preferably, the clamping member 3 includes a sliding plate 301, a clamping plate 302 and a compression spring 303. The clamping plate 302 is fixed to one side of the sliding plate 301. The side of the clamping plate 302 away from the sliding plate 301 can abut against the infrared thermal imager body 1. The side of the clamping plate 302 away from the infrared thermal imager body 1 is connected to the inner side of the placement frame 2 via the compression spring 303, so that the two clamping plates 302 can clamp and fix the infrared thermal imager body 1 under the action of the compression spring 303.
[0020] In one embodiment of this application, preferably, an inclined guide plate 11 is provided on the rear side of the clamping plate 302. The setting of the guide plate 11 facilitates the placement of the infrared thermal imager body 1 between the two clamping plates 302.
[0021] In one embodiment of this application, preferably, the branch pipe 4 is provided with a plurality of positioning holes evenly distributed in the vertical direction, the support rod 5 is provided with a limiting groove, and a T-shaped column 12 is slidably connected in the limiting groove. One end of the T-shaped column 12 can be inserted into the corresponding positioning hole, and the other end of the T-shaped column 12 is connected to the support rod 5 via a spring. By adjusting the height position of the placement frame 2 as needed, the T-shaped column 12 is then inserted into the corresponding positioning hole under the action of the spring.
[0022] In one embodiment of this application, preferably, a positioning seat 13 is fixed on the rotating column 8, and an insertion rod 14 is slidably connected to the positioning seat 13. Insertion holes 15 are respectively opened on both sides of the placement frame 2. Multiple insertion holes 15 on the same side are arranged in a circular array with the center line of the rotating column 8 as the axis. The insertion rod 14 can be inserted into the corresponding insertion hole 15. When the mounting bracket 9 is installed, the placement frame 2 can rotate on the rotating column 8, thereby adjusting the angle of the placement frame 2. Then, by inserting the insertion rod 14 into the corresponding insertion hole 15, the angle position of the placement frame 2 is fixed.
[0023] In use, this invention allows for the selection of a suitable installation point near the blast furnace based on the environment. Depending on the installation point, the mounting bracket 9 can be installed at a certain height using bolts, or the device can be supported on the ground at a suitable location using the support legs 7. When the device is installed on a wall or other external structure using the mounting bracket 9, the placement frame 2 can be rotated using the rotating column 8. Then, by inserting the insertion rod 14 into the corresponding insertion hole 15, the angle position of the placement frame 2 is fixed, facilitating the adjustment of the angle of the infrared thermal imager body 1. This allows for easy adjustment of the device according to actual needs. When installed using the mounting bracket 9, the support legs 7 are in a retracted state, saving space. When the device needs to be installed on the ground, the multiple support legs 7 are spread out, the height position of the support rod 5 within the support pipe 4 is adjusted, and then the T-shaped column 12 is inserted into the corresponding positioning hole under the action of the spring, facilitating the adjustment of the height position of the infrared thermal imager body 1. This design is convenient to use and avoids the need for operators to use portable thermometers or thermal imagers to measure the temperature of the blast furnace shell. It enables continuous monitoring of temperature changes, providing a good early warning function without affecting the production process and ensuring personnel safety.
