[0024] To make the technical means, creative features, achieved objectives, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Embodiment 1

[0026] Please refer to Figures 1-3, the present utility model provides a technical solution for a CT / DR two-in-one spectral detection system applied to the classification and identification of ores: including a storage box 1 for placing a detector 5, a movable platform 2 for placing ores 4, and an X-ray light source 3; the detector 5 and the X-ray light source 3 respectively correspond to the ore 4 on the movable platform 2.

[0027] Specifically, the X-ray light source 3 used is from Moxtek, model TUB000146-W06, with a tube voltage of 60 kV and a power of 12 W, providing a digital control instruction protocol for secondary development. The movable platform 2 is an existing three-axis servo motion platform produced by Beijing Saifan Optoelectronics Co., Ltd. The detector 5 is an existing CdTe photon counting detector 5. The ores 4 to be rotated are chalcopyrite, pyrite, and silica ores 4, which are three types of mineral resources with similar compositions and high sorting difficulties that often appear in the same ore deposit in actual production as the collected samples.

[0028] The ore 4 rotates through the movable platform 2, enabling the X-ray light source 3 to irradiate the horizontal toroidal surface P1 of the ore 4 to form a CT scan. The horizontal toroidal surface P1 is defined as the horizontal plane starting from the light point B where the X-ray light source 3 irradiates the ore and where the ore 4 rotates at least one full circle.

[0029] Furthermore, to facilitate the positioning of the X-ray light source 3 on the ore 4, the X-ray light source 3 is positioned through an infrared laser group 8: Preferably, a beryllium window 9 is provided on the front side of the X-ray light source 3; the infrared laser group 8 includes 2 infrared lasers 81, and the 2 infrared lasers 81 are respectively arranged on the central horizontal line and the central vertical line of the X-ray light source 3; the infrared laser 81 is an existing one-dimensional planar laser, and the light planes A of the 2 infrared lasers 81 intersect on the beryllium window 9 to form an intersection point A. The center of the X-ray light source 3 corresponds to the intersection point A, enabling the center of the X-ray light source 3 to pass through the beryllium window 9 and fall on the ore 4, thereby improving the measurement accuracy. During this period, the centers of the detector, the ore, and the X-ray light source are on the same straight line in the initial state.

[0030] Furthermore, the 2 infrared lasers 81 are adjusted in orientation using an existing universal bracket 82 to preferably form the intersection point A at the center of the beryllium window 9, and to finely adjust the placement position of the X-ray light source 3 so that the center of the X-ray light source 3 falls on the intersection point A.

[0031] To protect the circuit chip on the detector 5, a lead plate 6 is provided on the side of the storage box 1 corresponding to the ore 4, and strip-shaped lead slits 7 are provided on the lead plate 6. The detector 5 acts on the ore 4 through the lead slits 7.

[0032] Working principle: Place the ore 4 on the movable platform 2, then turn on the infrared laser group 8, and use the universal support 82 to adjust the light plane A of the infrared laser 81 so that the light planes A of the two infrared lasers 81 intersect (in a "cross" shape) on the beryllium window 9 and form an intersection point A. Then, finely adjust the X-ray light source 3 so that the center of the X-ray light source 3 corresponds to the intersection point A, and the center of the X-ray light source 3 passes through the beryllium window 9 and falls on the ore 4; then start the movable platform 2, and the movable platform 2 drives the ore 4 to rotate. The detector 5 acquires the spectral information of the X-ray light source 3 starting from the intersection point A after the ore 4 rotates one week.

[0033] Embodiment 2

[0034] Refer to Figure 1 、 2 、4. Different from Embodiment 1, the photon counting detector 5 is replaced with a DT linear array photon counting detector 5, and the pixel points of the detector 5 are arranged along the lead slit 7 (using the existing detector 5 with the model X-CARD ME). The storage box 1 is placed upright so that the lead slit 7 is horizontal.

[0035] The ore 4 is horizontally moved through the movable platform 2 so that the X-ray light source 3 irradiates the horizontal long surface P2 of the ore 4; define the horizontal toroidal surface P2 as the horizontal plane starting from the light spot B where the X-ray light source 3 irradiates the ore and the ore 4 displaces along the direction of the lead slit 7. The detector 5 acquires the spectral information of the length of the X-ray light source 3 starting from the intersection point A and the ore 4 displacing along the direction of the lead slit 7.

[0036] Embodiment 3

[0037] Refer to Figure 1 、 2 、5. Different from Embodiment 2, the storage box 1 is rotated 90°, so that the lead slit 7 is a vertical line.
