Device for automatically detecting moisture of powdery energetic material

Abstract

The invention discloses a device for automatically detecting moisture of a powdery energetic material. The device comprises a sampling device, a detection device, an air blowing device and an automatic control system. The automatic control system is connected with the sampling device, the detection device and the air blowing device through a control loop, and online sampling, moisture detection and sample returning are achieved through preset programs. By arranging the air blowing device, it is guaranteed that a transmission part and a dustproof box where the detection device is located are always in a positive pressure state in the sampling process, dust is isolated, and the requirement for extremely-high-grade explosion prevention in the energetic material moisture detection process is met, and the blowing device blows the detection probe and the sampling spoon, so that the influence on the measurement precision in a humid environment is eliminated. The problem that a near-infrared online moisture analysis method is used and popularized in online detection of the moisture of the powdery energetic material is successfully solved.

Description

technical field [0001] The invention belongs to the field of moisture detection equipment for energetic materials, and in particular relates to a device for automatically detecting the moisture of powdery energetic materials. Background technique [0002] In the production process of existing powdery energetic materials, the moisture determination usually adopts the oven method and the Karl Fischer electricity method. The oven method adopts the method of drying and weighing, and the measurement cycle is longer; Dissolve the energetic material sample to be tested in the electrolyte, but the current common energetic materials such as RDX and HMX cannot meet the requirements of the measurement due to their poor solubility. Moreover, the above two analysis methods require a series of operations such as sampling, inspection, and analysis. The measurement takes a long time and the measurement results lag behind. These defects make the commonly used energetic material moisture dete...

Problems solved by technology

[0004] What the present invention aims to eliminate is that the commonly used energy-containing material moisture detection method in the prior art has the defects that the detection period is long, the measurement result lags behind, and due to the special physical and chemical characteristics of the tested sample, the existing detection method is not suitable for moisture measurement.

As well as the influence of the external humid environment on the measurement accuracy when the near-infrared detection method is used for on-line moisture detection of powdery energetic materials, and the problem that it cannot meet the requirements of higher-level explosion-proof, a method for automatically detecting the moisture content of powdery energetic materials is proposed. installation
