Description

Technical Field

[0001] This utility model belongs to the technical field of temperature monitoring equipment, and relates to an infrared temperature measuring device for a nickel smelting outlet. Background Technology

[0002] The top-blown furnace employs an oxygen-enriched nickel smelting process. The system's process flow utilizes oxygen-enriched top-blown immersion lance smelting followed by PS blowing. In this top-blown nickel smelting system, precise control of the melt temperature is crucial for product quality and process stability. Traditional temperature measurement methods involve personnel holding a temperature gun and inserting the tip into the melt at the discharge port to monitor the melt temperature during discharge. This operation not only poses safety risks but also introduces errors due to the instability of human operation. Furthermore, wired thermocouple temperature monitoring is discontinuous, and the measurement time is highly dependent on the operator, allowing only measurements at a specific point in time and failing to provide real-time continuous temperature monitoring throughout the discharge process, resulting in a measurement blind spot. If a temperature sensor is installed at the nickel smelting discharge port for continuous temperature measurement, the sensor is easily damaged due to prolonged exposure to high temperatures, rendering it unable to perform normal detection. Utility Model Content

[0003] The purpose of this utility model is to provide an infrared temperature measuring device for nickel smelting outlets, addressing the problems existing in the prior art.

[0004] Therefore, the present invention adopts the following technical solution: An infrared temperature measuring device for a nickel smelting outlet includes a mounting frame. An infrared thermometer is mounted on the mounting frame. A heat-conducting plate is provided on each side of the infrared thermometer. The heat-conducting plate has an arc-shaped slot. The infrared thermometer is located in the slot. A semiconductor refrigeration chip is provided on the side of the heat-conducting plate away from the slot. One side of the semiconductor refrigeration chip forms a cooling surface, and the other side forms a heat dissipation surface. The cooling surface abuts against the heat-conducting plate.

[0005] Furthermore, the heat-conducting plate is fixed to the mounting bracket.

[0006] Furthermore, a heat sink is provided on the heat dissipation surface of the semiconductor cooling chip, and the heat sink is mounted on a mounting bracket.

[0007] Furthermore, a cooling fan is installed on the heat sink.

[0008] The beneficial effects of this utility model are as follows: semiconductor cooling chips are set on both sides of the infrared thermometer, and the infrared thermometer is cooled down by the semiconductor cooling chips, which effectively prevents the infrared thermometer from rising in temperature at the nickel smelting outlet for a long time, affecting normal use. In addition, the infrared thermometer can be installed at the nickel smelting outlet to measure the temperature of the melt in real time, saving manpower and improving monitoring efficiency; the structure is simple and the cost is low.

Detailed Implementation

[0010] The present invention will now be described in detail with reference to the accompanying drawings: like Figure 1 and 2 As shown, an infrared temperature measuring device for a nickel smelting outlet includes a mounting frame 1, which can be installed at the outlet of a smelting furnace. An infrared thermometer 2 is mounted on the mounting frame 1. The infrared thermometer 2 is a conventional infrared thermometer with a cylindrical structure, capable of measuring the temperature of the molten material at the outlet. A heat-conducting plate 3 is located on each side of the infrared thermometer 2, fixed to the mounting frame 1. The heat-conducting plate 3 is made of a conventional metal material with good thermal conductivity. A semi-circular slot 4 is provided on the heat-conducting plate 3 to increase the contact area between the heat-conducting plate 3 and the infrared thermometer 2, improving the cooling effect. The infrared thermometer 2 is located within the slot 4. A semiconductor cooling chip 5 is located on the side of the heat-conducting plate 3 away from the slot 4. The semiconductor cooling chip 5 is a conventional semiconductor cooling chip. One side of the semiconductor cooling chip 5 forms a cooling surface 501, and the other side forms a heat dissipation surface 502. During use… The cooling surface 501 cools down the infrared thermometer 2, while the heat dissipation surface 502 heats up the infrared thermometer 2. The cooling surface 501 is pressed against the heat-conducting plate 3, and cooling is achieved through the cooling surface 501, which in turn cools the heat-conducting plate 3, thereby cooling the infrared thermometer 2 and keeping it within a suitable temperature range to prevent overheating in high-temperature environments. Since the semiconductor cooling chip 5 has a good cooling effect, it can ensure rapid and timely cooling of the infrared thermometer 2. In order to cool down the heat dissipation surface 502 and dissipate its temperature in a timely manner to prevent the heat dissipation surface 502 from overheating, a heat sink 6 is provided on the heat dissipation surface 502 of the semiconductor cooling chip 5. The heat sink 6 is mounted on the mounting bracket 1. The heat sink 6 can be a conventional computer CPU heat sink. A cooling fan 7 is also installed on the heat sink 6. The cooling fan 7 can be a conventional computer CPU cooling fan.

[0011] The method of using this utility model is as follows: Install the mounting bracket 1 at the discharge port of the smelting furnace. The infrared thermometer 2 on the mounting bracket 1 can continuously measure the temperature of the melt at the discharge port of the smelting furnace. When in use, the semiconductor cooling chip 5 can be turned on to cool the infrared thermometer 2 through the cooling surface 501 of the semiconductor cooling chip 5 and the heat conduction plate 3 to cool the infrared thermometer 2. This prevents the infrared thermometer 2 from overheating and becoming unusable in a high-temperature environment for a long time, and ensures that the temperature of the infrared thermometer 2 is within the normal range. While cooling the infrared thermometer 2, the cooling fan 7 also needs to be turned on to cool the heat dissipation surface 502 of the semiconductor cooling chip 5 through the heat sink 6 to prevent the heat dissipation surface 502 from overheating.

[0012] This device can effectively prevent the infrared thermometer 2 from being unable to function properly due to excessively high temperature at the furnace outlet for extended periods, thereby enabling the infrared thermometer 2 to continuously measure the temperature of the melt in real time.
