Abstract

Technical Field
[0001] This application relates to the field of spectral temperature measurement technology in tin smelting, and in particular to a multi-band temperature measurement device for tin metallurgy. Background Technology
[0002] Tin smelting refers to the process of using tin ore (such as tin concentrate, tin-containing waste, etc.) as raw material, and through a series of physical and chemical reactions and processes such as beneficiation, smelting, reduction, refining, and casting, to remove impurities and extract metallic tin (or tin alloys), and finally produce tin ingots, tin alloys and related products that meet industrial standards. It is a key link in the tin industry chain from raw materials to finished products.
[0003] In order to accurately control the temperature of each process and ensure product quality, equipment safety, energy efficiency and process stability, it is necessary to measure the temperature of materials (such as tin concentrate, molten tin, tin alloy melt, etc.) and related equipment (such as smelting furnace, heating system, furnace body, etc.) in each process of tin smelting.
[0004] In traditional tin smelting processes, temperature measurement is typically performed using infrared thermometers. However, infrared thermometers are easily affected by the radiation characteristics of the metal surface (such as emissivity, reflectivity, and absorptivity), leading to deviations in the measured temperature and consequently reducing measurement accuracy.

[0039] Example 1:
[0040] See Figure 1 A multi-band temperature measurement device for tin metallurgy includes an infrared camera, a laser device, a visible light device, an optical fiber assembly, a spectrum analyzer, and a laser generator. The multi-band temperature measurement device for tin metallurgy further includes:
[0041] Box 1;
[0042] The mounting slot 2 located at the rear end of the housing 1 is used to install the spectrometer and the laser generator;
[0043] The mounting hole group opened on the front wall of the housing 1 is used for the front end of the infrared camera, laser device, visible light device and fiber optic assembly to pass through and be positioned.
[0044] An adjustable support assembly 3 is located at the front end inside the housing 1, which is used to allow the infrared camera, laser device, visible light device and fiber optic assembly to pass through and be positioned in the middle and rear.
[0045] Specifically, the mounting hole group is used for the front end of the infrared camera, laser device, visible light device and fiber optic assembly to pass through, so as to support and position the front end of the above optical devices. The adjustable support assembly 3 is installed inside the front end of the housing 1. The middle and rear parts of the infrared camera, laser device, visible light device and fiber optic assembly pass through the adjustable support assembly 3 to support the rear end of the above optical devices and position the axis of the above optical devices on the same horizontal plane, thereby ensuring that each optical device can be stably and accurately aligned with the tin smelting area.
[0046] The fiber optic assembly receives the spectral radiation signals generated during the tin smelting process and transmits them to a spectrometer for analysis and processing. The processed data is then transmitted to a computer. Fiber optic transmission effectively reduces signal attenuation and interference, ensuring the accuracy of the measurement data. A laser is used for precise positioning of the tin smelting area, assisting in the measurement work. The laser beam's emission direction is adjusted via an adjustable support assembly 3 to ensure accurate illumination of the area to be measured. An infrared camera is used to acquire real-time infrared image information of the tin smelting process; the camera's signal cable is connected to the data processing computer.
[0047] When the tin smelting process begins, infrared cameras, lasers, visible light devices, and fiber optic assemblies work together to acquire real-time temperature and spectral data of the smelting area. The laser assists in positioning, ensuring accurate alignment of each measuring device; the infrared camera acquires infrared images of the molten tin, while the visible light device captures images in the visible light band. Through the fiber optic assembly, spectral signals during the smelting process are collected and transmitted to a spectrometer for analysis. The processed data analysis results generate temperature field distribution maps and composition analysis reports, helping operators monitor and adjust the smelting process in real time. In this way, by integrating infrared cameras, lasers, visible light devices, and fiber optic assemblies into enclosure 1 for collaborative operation, multi-band spectral information is acquired and fused for analysis. This eliminates the reliance on infrared thermometry, which is affected by the radiation characteristics of the metal surface, thus accurately obtaining temperature information and effectively avoiding measurement deviations caused by the radiation characteristics of the metal surface, thereby improving measurement accuracy.
[0048] It should be noted that the adjustable support assembly 3 has an adjustment function. By adjusting the position of each optical component, the axes of all optical components are aligned on the same horizontal plane, thereby avoiding measurement errors caused by positional offset. The adjustment method will be given in Embodiment 2.
[0049] In addition, infrared cameras, lasers, visible light devices, spectral analyzers, and laser generators are all existing technologies and are not shown in the figure. Their structures will not be described in detail here.
[0050] Example 2:
[0051] See Figure 2 Based on Embodiment 1, optionally, the adjustable support component 3 includes:
[0052] The infrared base 4, the fiber optic base 5, the laser base 6, and the visible light base 7 are arranged sequentially along the width direction inside the housing 1.
[0053] Among them, the upper ends of the infrared base 4, the fiber optic base 5, the laser base 6 and the visible light base 7 are respectively equipped with an infrared fixing collar 8, a fiber optic fixing collar 9, a laser fixing collar 10 and a visible light fixing collar 11.
[0054] Specifically, the aforementioned bases are set at different heights to adjust the height of each optical component and ensure that all components are level. The middle and rear portions of the infrared camera, fiber optic assembly, laser, and visible light device are respectively inserted into the infrared fixing collar 8, fiber optic fixing collar 9, laser fixing collar 10, and visible light fixing collar 11 for support.
[0055] Optionally, the infrared fixing collar 8, the fiber optic fixing collar 9, the laser fixing collar 10, and the visible light fixing collar 11 are each provided with three threaded holes in the radial direction, and an adjusting screw is threaded into each of the threaded holes.
[0056] The three threaded holes are arranged in a circumferential array with equal spacing.
[0057] Specifically, the included angle between the three threaded holes is 120 degrees. The position of each optical component is fixed and adjusted by rotating the length of the adjusting screw to ensure that their axes are on the same horizontal plane.
[0058] Optionally, the mounting hole assembly includes:
[0059] Infrared aperture 12, fiber optic aperture 13, laser aperture 14 and visible light aperture 15 are arranged sequentially along the length of the front wall of the housing 1.
[0060] Among them, infrared aperture 12, fiber optic aperture 13, laser aperture 14 and visible light aperture 15 correspond one-to-one with the infrared camera, laser device, visible light device and fiber optic assembly, respectively.
[0061] Specifically, the dimensions of the infrared aperture 12, fiber optic aperture 13, laser aperture 14, and visible light aperture 15 are 38mm, 58mm, 22mm, and 28mm, respectively. The centers of the four apertures are all located on the same horizontal plane, and the positions of the four apertures are evenly distributed to ensure that each optical device can stably and accurately align with the tin smelting area and to ensure that each device can collect target data without interference.
[0062] Optionally, the fiber optic assembly includes a lens 16 and a focal length adjustment device 17, which are threadedly connected.
[0063] Specifically, lens 16 is used to focus spectral information during the metal smelting process. The focal length adjustment device 17 adjusts the appropriate focal length so that the optical fiber receives the spectral information and transmits it to the spectrometer for further analysis and processing. The bottom of lens 16 and the middle of focal length adjustment device 17 are provided with mutually mating threads. The optical fiber focal length adjustment is achieved by rotating the threads at the bottom of the threaded lens 16 and the threads of the focal length adjustment device 17.
[0064] See Figure 3 Optionally, the spectrometer and the laser generator are separated by a partition 18.
[0065] Specifically, the laser generator can interfere with the spectrometer's accurate detection and analysis of weak spectral signals, leading to measurement deviations. The partition 18 effectively blocks laser and electromagnetic radiation, ensuring stable operation of the spectrometer and accurate analysis of the spectral signals transmitted from the optical fiber, thereby improving the measurement accuracy of the multi-band temperature measurement device.
[0066] Optionally, a straight slot 19 is provided on the rear wall of the housing 1, and the infrared camera, laser device, visible light device, fiber optic assembly, spectrometer and laser generator are connected to the computer through the straight slot 19.
[0067] Specifically, the laser device and laser generator are connected by optical fiber to ensure that the laser measurement is not affected by environmental electromagnetic interference and to guarantee measurement accuracy. The laser generator is connected to the computer cable through a straight slot 19 to ensure the stable and accurate operation of the laser measurement system. The laser generator produces laser light, and the laser device emits laser light to accurately locate the tin smelting area, assisting in the measurement work.
[0068] The visible light device is connected to the computer via an image acquisition card and a cable. After acquiring a visible light image of the smelting area, the device first transmits the image signal to the image acquisition card. The image acquisition card is typically installed in an expansion slot inside the computer's main unit, and the visible light device is connected to the image acquisition card via a cable. This cable is usually a dedicated video cable for transmitting image signals, such as an HDMI cable or a USB video cable; the visible light device can also be directly connected to the computer via a USB cable.
[0069] In addition, the fiber optic assembly is connected to the spectrometer via fiber optic cable, and the spectrometer is connected to the computer via a straight slot 19 fiber optic cable. Since the connection method for the infrared camera has already been mentioned, it will not be repeated here.
[0070] See Figure 2 Optionally, the top of the box body 1 is movably provided with a rotating box door 20.
[0071] Specifically, the rotating door 20 is installed on the top of the enclosure 1 and connected to the enclosure via hinges or similar rotating connectors, providing excellent rotational flexibility. During equipment installation and maintenance, the rotating door 20 is easy to open, allowing technicians to easily access the infrared camera, laser, visible light devices, fiber optic components, and other equipment inside the enclosure. This facilitates installation, debugging, repair, and replacement of parts, improving work efficiency. Simultaneously, closing the rotating door 20 effectively protects the internal precision optical components, reducing the corrosion from dust, moisture, and other impurities, and extending the equipment's lifespan. During temperature measurement, closing the rotating door 20 blocks external light and interference sources, creating a stable working environment for the internal optical components and preventing external light from interfering with measurement data. This ensures that the multi-band temperature measurement device accurately collects temperature and spectral data during the tin smelting process, improving measurement accuracy and reliability.
[0072] This application also achieves the following effects:
[0073] Multi-band information fusion: This application can simultaneously collect spectral information from different bands and perform fusion analysis to achieve accurate monitoring of temperature and composition and optimize smelting control.
[0074] Enhanced stability and reliability: The design of laser-assisted positioning and adjustable support component 3 ensures stable operation of the equipment over a long period of time and avoids errors caused by positional deviation.
[0075] Improving production efficiency and quality: Precise temperature control helps improve the stability of the smelting process, reduce raw material waste, and improve production efficiency and product quality.
[0076] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.
[0077] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
