Background Art

[0002] In the metallurgical industry, metallurgical melts need to be analyzed for composition after they come out of the furnace to confirm whether the quality of the product meets the standards and ensure that it matches the subsequent production process, thereby guiding the subsequent material ratio. In the process of component detection, laser induced breakdown spectroscopy is widely used. This technology focuses laser pulses on the sample surface to stimulate plasma generation, and uses a spectrometer to analyze its emission spectrum, thereby identifying the elemental composition in the sample and completing qualitative and quantitative analysis of the material.

[0003] However, in metallurgical production sites, due to the existence of harsh environments such as high temperature, dust and rainfall, the electrical control boxes of the detection equipment are often adversely affected, causing problems such as circuit boards and components getting damp and short circuits, which in turn affects the accuracy of detection and causes large measurement errors.

[0004] Therefore, how to design a device that can adapt to harsh working environments and effectively protect the electric control box and its electronic components has become an important issue that needs to be urgently solved by those skilled in the art. Summary of the invention

[0006] Sealing structure: The sealing structure of the electric control box adopts multiple sealing technologies, including rubber sealing rings and sealants, to ensure IP67 or higher protection level to prevent dust and moisture intrusion.

[0007] Corrosion-resistant materials: Internal circuit boards and components are made of high-temperature and corrosion-resistant materials, such as gold-plated circuit boards and stainless steel casings, to improve the corrosion resistance and conductivity of the circuits.

[0008] Modular component design: Designed with modular components that are easy to disassemble and replace, connected to the bottom plate inside the shell through a pull-out design to facilitate maintenance and upgrades.

[0009] Temperature control and dehumidification system: The temperature control and dehumidification system is fixed on the right side of the outer shell, and includes a compressor, an outdoor heat exchanger, a first and a second indoor heat exchanger, a water tank and a liquid storage device. It can realize cooling + hot water making, heating + hot water making and dehumidification + hot water making modes, and can also adapt to the refrigerant circulation volume in different modes to solve the problem of high power consumption. The system runs efficiently and can effectively control the temperature and humidity inside the electrical control box.
