Abstract: The present disclosure discloses a mobile radiation inspection apparatus and a mobile radiation inspection system, relates to the field of security inspection, and is used for expanding functions of the mobile radiation inspection apparatus. The mobile radiation inspection apparatus includes a vehicle body, a traveling mechanism, a boom assembly, a first imaging device, and a second imaging device. The boom assembly is mounted on the vehicle body and is configured to switch between an inspection state and a transportation state. The first imaging device includes a first ray source and a first ray detector both mounted on the boom assembly. The first ray source is positioned at the top of an inspection channel. The second imaging device includes a second ray source and a second ray detector. The second ray detector cooperates with the second ray source to detect rays emitted by the second ray source, and the second ray source is positioned on a side surface of the detection channel. The mobile radiation inspection apparatus provided by the technical solutions implements multi-angle and multi-mode scanning.

Abstract: The present disclosure discloses a vehicle-mounted type back scattering inspection system comprising a carriage (1) and a back scattering imaging device (2). The back scattering imaging device has a vehicle-mounted working state and a ground working state, and in the vehicle-mounted working state, the back scattering imaging device performs inspection work in the carriage; in the ground working state, the back scattering imaging device performs the inspection work on the ground at the outside of the carriage; and the back scattering imaging device is separately arranged relative to the carriage and is movable between the carriage and the ground to switch between the vehicle-mounted working state and the ground working state. The back scattering imaging device of the vehicle-mounted type back scattering inspection system is separately arranged relative to the carriage and is movable between the carriage and the ground, in a scene where the vehicle cannot enter, the back scattering imaging device can move from the carriage to the ground to switch to the ground working state so as to perform the inspection work, thereby expanding the applicable range of vehicle-mounted type back scattering inspection system.

Abstract: The present application discloses a multi-view backscatter inspection system and an inspection method. The inspection system comprises an inspection passage, at least two inspection units, a control device and a data processing device. The inspection unit comprises a radiation source and a detector array. The detector array comprises at least two detector modules arranged at different positions and independent of each other. At least two inspection units are arranged so that a radiation beam from any inspection unit is directed to the outside of the detector array of each of the remaining inspection units. The control device adjusts a phase difference between radiation beams of various radiation sources, so that an effective detection area of each of the detector arrays is far away from an interference area. When an inspection image corresponding to certain detector array at certain moment is formed, the data processing device calculates an effective detection area of the detector array at the moment, processes a detection signal from a detector module within the effective detection area and forms an inspection image in which the inspection target is located at one side of the detector array at the moment. The present application may improve the quality of an inspection image.

Abstract: A mineral separation device includes a conveying mechanism (10), a backscattering mechanism (20), and a spraying mechanism (30). The conveying mechanism (10) is configured to convey an ore so that the ore leaves from a discharge end of the conveying mechanism (10) and moves along a first trajectory; the backscattering mechanism (20) is provided below the conveying mechanism (10), and the backscattering mechanism (20) includes a backscattering emitter (21) configured to emit rays to the ore and a backscattering detector (22) configured to receive rays scattered from the ore to acquire a backscatter image; the spraying mechanism (30) is located below the backscattering mechanism (20), and the spraying mechanism (30) is configured to spray, according to a comparison result between a grayscale value of the backscatter image and a predetermined grayscale value, a high-pressure fluid to cause a portion of the ore to move along a second trajectory. By providing the backscattering mechanism (20) below the conveying mechanism (10), structures of the mechanisms of the mineral separation device are compact, and an overall size of the mineral separation device is reduced.
