Portable explosive detector for airport security check

Abstract

The invention discloses a portable explosive detector for airport security check. The detector comprises a shell and an installation box. The lower end of the shell is fixedly connected with a lower expansion plate through a fixing plate, the upper end of the shell is fixedly connected with an upper expansion plate through a fixing plate, and meanwhile a third working pipe is fixedly installed inthe shell. A first working pipe is fixedly installed in the upper expansion plate, a second working pipe is fixedly installed in the lower expansion plate, the right side of the third working pipe iscommunicated with a communicating pipe, the communicating pipe is communicated with a detection channel through a fixing pipe, meanwhile, the right end of the detection channel is fixedly connected with an exhaust pipe, and the lower end of the exhaust pipe is communicated with an air inlet of a draught fan. According to the portable explosive detector for airport security check, the upper expansion plate and the lower expansion plate are installed on the upper side and the lower side of the shell, so that the detection area of the detector is increased, and the detection efficiency of the detector is improved; the fatigue feeling of the hands is relieved, and the detection work is convenient to carry out.

Description

technical field [0001] The invention relates to the technical field of explosive detection, in particular to a portable explosive detector for airport security inspection. Background technique [0002] Generally speaking, explosive detectors are used in airports, seaports, railway stations, government agencies and public places threatened by terrorists. The current methods for detecting explosives include X-ray diffraction by gas chromatography, Raman spectrometer, nuclear quadruple Resonance, energy dispersive, portable metal detectors and mass spectrometers for seed diffraction analysis. These detectors need to analyze the physical characteristics of explosives. Once the samples they screen are close to explosives, they are prone to false detections; such as metal detection Detector just detects by analyzing the composition of explosives, but when there are metal detectors similar to explosives around, existing metal detectors just cannot work normally; No.: CN20162078910...

[0002] Generally speaking, explosive detectors are used in airports, seaports, railway stations, government agencies and public places threatened by terrorists. The current methods for detecting explosives include X-ray diffraction by gas chromatography, Raman spectrometer, nuclear quadruple Resonance, energy dispersive, portable metal detectors and mass spectrometers for seed diffraction analysis. These detectors need to analyze the physical characteristics of explosives. Once the samples they screen are close to explosives, they are prone to false detections; such as metal detection Detector just detects by analyzing the composition of explosives, but when there are metal detectors similar to explosives around, existing metal detectors just cannot work normally; No.: CN201620789105.4) A portable molecular detector for explosives. The article proposes that "the air channel is provided with an air channel connected to the air inlet, and multiple detection elements for detecting and sensing the air concentration are installed on the air channel;" The air path inside the inlet casing sucks the outside air into the device for detection. The size of the inlet casing is too small. When the flow of people is large, the detection efficiency of passengers is too low. In severe cases, passengers may be stranded; at the same time Holding the handle, it is very inconvenient to operate by aiming at passengers through the imported shell at the front end
