[0026] The thermal imager cooling protection cylinder is supported at a suitable working position, so as to ensure that the thermal imager 7 can accurately detect the upper part of the steel ladle and ensure the stability of the device during the working process, thereby preventing the detection accuracy and equipment safety from being affected due to shaking or displacement.

[0027] The air knife frame 3 is installed at the front end of the mounting cylinder 1, the air direction is vertically downward, and the structure design can effectively guide the airflow to act on the lens area of the thermal imager.

[0028] When the compressed air is delivered to the air knife frame 3 through the air supply hose 4, the air knife frame 3 guides the airflow to form an air curtain to block dust from approaching the lens of the thermal imager, and at the same time, the airflow is used to carry away the heat around the lens, thereby playing a dual role of cooling and dust removal, and reducing the influence of environmental factors on the imaging result.

[0029] One end of the air supply hose 4 is connected to the air knife frame 3 and the mounting cylinder 1, and the other end is connected to the air compression pump, which usually has good flexibility and sealing performance, can withstand a certain air pressure, and the material can be high-temperature-resistant and corrosion-resistant rubber or plastic.

[0030] As a delivery channel for compressed air, the air supply hose 4 stably delivers the cooling compressed air generated by the air compression pump to the air knife frame 3, provides a continuous airflow source for the air knife frame 3, ensures the normal operation of the cooling and dust removal functions, and is one of the key components for realizing the automatic cleaning and cooling functions of the device.

[0031] The rear cover plate 5 is installed at the rear end of the mounting cylinder 1 and tightly cooperates with the mounting cylinder 1, and the rear cover plate 5 is provided with a wire connection hole 6.

[0032] The rear end of the mounting cylinder 1 is closed to protect the internal thermal imager 7 and the line connection part from the invasion of impurities such as dust and water vapor, and at the same time, the wire connection hole 6 is provided for the thermal imager 7 to provide a power connection channel, ensure the normal power supply of the thermal imager 7, and maintain the electrical performance and working stability of the equipment.

[0036] The temperature field of the molten steel measuring rod is detected by using the infrared imaging technology, the height of the molten steel liquid surface and the thickness of the slag are judged by analyzing the temperature data, which is the core detection component of the whole device, and provides key data support for the slag detection and liquid level control in the steel smelting process.

[0037] The flange plate 8 is installed inside the installation cylinder 1 at the front end of the thermal imager 7, ventilation holes 9 are arranged around the flange plate 8, and the flange plate 8 is closely matched with the installation cylinder 1 and the thermal imager 7.

[0038] On the one hand, the flange plate 8 plays a certain fixing and supporting role for the thermal imager 7, and ensures the position stability of the thermal imager 7 in the installation cylinder 1; on the other hand, the ventilation holes 9 can make the cooling air flow form a reasonable air circulation at the front end of the thermal imager 7, assist the air knife frame 3 to cool and dust, and improve the protection effect of the equipment.

[0039] The ventilation holes 9 are arranged around the flange plate 8, the shape, size and number of which are designed according to the heat dissipation and dust removal needs of the thermal imager 7, and are usually circular or rectangular and uniformly distributed, so as to ensure that the air flow can uniformly pass through the flange plate 8 to the front end of the thermal imager 7.

[0040] As a flow passage of the cooling air flow, the ventilation holes 9 make the cold air flow around the lens and the surrounding area of the thermal imager 7, enhance the cooling effect, and help to disperse the dust that may gather at the front end of the thermal imager 7, keep the lens clean, and improve the imaging accuracy.

[0045] During the steel smelting process, the thermal imager cooling protection cylinder starts to operate. The compressed air generated by the air compressor pump is delivered to the air knife holder 3 through the air supply hose 4.
