Description

Technical Field

[0001] The utility model relates to the field of granary detection, in particular to a fixed real-time detection device used for a granary. Background Art

[0002] With the development of the times, my country's agriculture has continued to develop, and now agricultural production has formed a certain scale. When the output of grain reaches a certain level, in addition to supplying the market for sale, there will be some surplus grain in the general annual output. Therefore, the surplus grain needs to be stored, and granaries are an important part of grain storage technology; one of the most important treatments in grain storage is pest control, and aluminum phosphide is generally used to treat the granary. Aluminum phosphide is a grain storage insecticide promoted and applied by the national grain department, but aluminum phosphide will deliquesce in a humid environment to generate highly toxic phosphine gas. Phosphine is a colorless, highly toxic, and flammable gas with a smell similar to that of stinky fish. If it encounters trace amounts of other phosphorus hydrides such as ethyl phosphine, it will cause spontaneous combustion. Inhalation of phosphine will affect the human heart, respiratory system, kidneys, stomach, nervous system, and liver, and seriously threaten the life safety of workers working inside the granary. In addition, its flammability also makes it an important safety hazard in granaries; oxygen concentration is also an important monitoring indicator for granaries. If the oxygen concentration is too low, it will cause vomiting or coma.

[0003] How to provide a device that can simultaneously detect the concentrations of oxygen and phosphine in a granary is a problem that needs to be solved by those skilled in the art. Utility Model Content
