Problems solved by technology

However, the scintillator itself has the characteristics of low photoelectric conversion efficiency and sensitivity, and is easily affected by scattering, which greatly limits the contrast and clarity of the image, and there is also a large overlap of photosensitive areas between different scintillators. , causing the information of the two channels to have greater mutual interference. These are the bottlenecks for DEXRT technology to achieve better performance in the field of online ore sorting

Abstract

The invention discloses an ore online sorting device. The ore online sorting device comprises a machine body machine frame. The machine body machine frame is provided with a discharge chute, a belt type conveying device, a ray source assembly, a ray detector, a pneumatic type executing assembly, a material collecting bin and a control device. The control device is electrically connected with the belt type conveying device, the ray source assembly, the ray detector and the pneumatic type executing assembly. The belt type conveying device comprises two belt shafts, a belt tensioned between the two belt shafts and a motor for driving one belt shaft to rotate. The belt penetrates through the space between the ray source assembly and the ray detector. The discharge chute is located on the upperside of one end of the belt. The pneumatic type executing assembly is close to the other end of the belt. The invention further provides a sorting method of the ore online sorting device. The ore online sorting device has the higher distinguishing precision and ray utilization rate and high material recognition capacity and can well replace manual operation, improve labor productivity and bettercomplete intelligent ore recognizing and sorting.

Description

technical field [0001] The invention relates to the technical field of ore machine visual recognition analysis and sorting, in particular to an online ore sorting device and a sorting method. Background technique [0002] At present, in the field of online ore sorting, the main detection technologies include visible light detection, near-infrared detection, laser detection, XRF (X-ray fluorescence spectroscopy), and XRT (X-ray transmission). Among them, only XRT can detect the internal composition of the ore, and other technologies can only detect the surface of the ore, so XRT has a unique advantage in the accuracy of identification, and thus has become the current mainstream ore sorting and detection technology. In the field of XRT detection, since Jacobson first proposed DEXRT (dual-energy X-ray transmission) imaging technology in 1953, DEXRT has been widely used in medical and industrial CT, airport and passenger station safety inspection, non-destructive testing and oth...
