Abstract

[0002] Direct reading spectrometers are widely used in metallurgy, machinery and other fields for the composition analysis of metal materials. They are characterized by high accuracy, fast speed and comprehensive analysis. However, due to the needs of the production analysis cycle before the steelmaking furnace, direct reading spectrometers often continuously excite and analyze multiple samples. The temperature of the excitation table will continue to rise as the equipment is continuously excited. However, too high an excitation table temperature will affect the accuracy of the analysis data. It is necessary to wait for the excitation table to cool down naturally before continuing the analysis of subsequent samples, which cannot meet the requirements of the detection cycle for the quick analysis before the furnace.

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] like Figure 1 , 2 As shown, a temperature-measurable direct-reading spectrometer excitation platform cooling device in this embodiment includes two cooling units arranged in parallel, and an adjustment mechanism is provided between the cooling units. The adjustment mechanism is used to adjust the spacing between the two cooling units so that the two cooling units are close to the two sides of the excitation platform 10 of different sizes to cool the excitation platform. A sensor bracket 4 and an instrument bracket 7 are fixed on the top of a cooling unit by welding or gluing. A non-contact infrared temperature sensor 3 is arranged on the sensor bracket 4. The non-contact infrared temperature sensor 3 is tilted downward so that the non-contact infrared temperature sensor 3 faces the upper surface of the excitation platform 10. An instrument 6 is arranged on the instrument bracket 7. The instrument 6 is electrically connected to the non-contact infrared temperature sensor through a signal line 5, and the power line 8 of the instrument 6 is connected to an external power supply. The non-contact infrared temperature sensor 3 detects the upper surface temperature of the excitation platform 10, and feeds back the detection result to the instrument, so that the staff can grasp the temperature status of the excitation platform in real time.
[0016] The cooling unit includes a hollow metal bin 1, which is a rectangular parallelepiped with a length of 135 mm, a height of 55 mm, and a width of 50 mm. The material is a metal with good thermal conductivity and is not easy to deform (such as copper, stainless steel, etc.), and the material thickness is 1 mm. One end of the hollow metal bin is an opening, and the ice bag is inserted into the hollow metal bin 1 through the opening 9. After the medium in the ice bag melts, the ice bag is taken out from the opening and put into the refrigerator for freezing, and the spare ice bag is taken out and inserted into the hollow metal bin again.
[0017] The material of the ice bag is polyethylene, and the main component of the ice bag is sodium polyacrylate. After freezing, the length of the ice bag is 125mm, the height is 45mm, and the width is 40mm. The size of the ice bag matches the inner cavity of the hollow metal bin.
[0018] The adjustment mechanism includes two telescopic connecting rods 2, and the two telescopic connecting rods 2 are arranged horizontally. The two ends of the telescopic connecting rod 2 are respectively provided with a base, and the base is fixed to the inner side of the hollow metal bin on the corresponding side. The telescopic connecting rod is close to the opening side of the hollow metal bin. The telescopic size of the telescopic connecting rod is 80-150mm, so that the telescopic connecting rod is elongated to be larger than the width of the excitation table of the direct-reading spectrometer, so that the excitation table can be placed between the two hollow metal bins, or the telescopic connecting rod is shortened to match the width of the excitation table of the direct-reading spectrometer, that is, the hollow metal bin is close to the two sides of the excitation table of the direct-reading spectrometer.
[0019] The present application has a simple structure and is easy to operate. It can continuously cool and monitor the temperature of the excitation stage, thereby improving the accuracy of continuous detection of samples by the direct-reading spectrometer and meeting the requirements of the detection cycle.
[0020] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
