Description

Technical Field

[0001] The invention relates to the technical field of calcium carbide detection, in particular to an automatic sampling device for calcium carbide. Background Art

[0002] Calcium carbide, whose chemical name is calcium carbide, is an inorganic compound, usually in the form of gray-black block or granular solid. It reacts violently immediately when it comes into contact with water to produce acetylene gas and release a large amount of heat. Acetylene is an important chemical raw material that can be used for metal cutting and welding, as well as the manufacture of synthetic rubber and artificial fibers. Calcium carbide is usually a gray-black or brown block or granular solid with a high density, moderate hardness and easy to break. Calcium carbide will decompose rapidly when it comes into contact with water to produce acetylene gas and calcium hydroxide. The production of calcium carbide usually involves the reaction of carbonaceous materials with limestone at high temperatures. This process requires strict control of reaction conditions and raw material quality to ensure product quality and safety.

[0003] During the production and storage of calcium carbide, the automated and safe sampling of calcium carbide at fixed times and fixed points is a key link to ensure the safe operation of the production process. Therefore, an automated sampling device for calcium carbide is needed to sample calcium carbide. The existing automated sampling device for calcium carbide usually needs to crush the calcium carbide first, but the inside and outside of the calcium carbide will be mixed together after crushing, which will affect the randomness of sampling. At the same time, when the calcium carbide is crushed, a large amount of dust will be generated, affecting the work of the sampling personnel. In addition, the existing automated sampling device for calcium carbide usually only screens the crushed calcium carbide once, which will result in the inability to completely separate the calcium carbide from impurities, resulting in the presence of impurities in the taken calcium carbide sample, affecting the calcium carbide detection results. Summary of the invention
