Description

Technical Field

[0001] This utility model relates to the field of ore sorting technology, and in particular to an X-ray transmission ore sorting and detection device. Background Technology

[0002] In the mining and ore processing industry, in order to improve the utilization rate of ore resources and reduce subsequent smelting costs, it is often necessary to remove waste rock from the ore through sorting equipment to purify the target ore.

[0003] In actual sorting operations, the posture of the ore to be sorted is highly random. When the ore is tilted or has a lateral protrusion, the light from the front light source cannot cover the lateral area of ​​the ore, resulting in a significant shadow area between the ore's side and the background. This shadow is directly superimposed on the transmitted optical signal received by the X-ray detection sensor, causing signal distortion. The signal distortion in the shadow area will cause the signal processing unit to misjudge the actual contour and density distribution of the ore, ultimately leading to a decrease in sorting accuracy and problems of "misselection" or "missed selection". To alleviate the shadow problem, some existing devices will increase the power of the front light source to enhance the irradiation intensity. However, this not only increases energy consumption, but may also cause excessive reflection on the ore surface due to direct strong light, further interfering with the stability of the transmitted optical signal. This cannot fundamentally solve the problem of clear signal acquisition for ores with different postures. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an X-ray transmission ore sorting and detection device. This device addresses the highly random nature of the ore's orientation during actual sorting operations. When the ore is tilted or has a lateral protrusion, the light from the front light source cannot cover the ore's lateral area, resulting in a significant shadow area between the ore's lateral side and the background. This shadow is directly superimposed on the transmission optical signal received by the X-ray detection sensor, causing signal distortion. This signal distortion in the shadow area causes the signal processing unit to misjudge the ore's actual contour and density distribution, for example, misidentifying the shadow area as a low-density part of the ore, or failing to accurately capture the compositional differences at the ore's edges. Ultimately, this leads to a decrease in sorting accuracy, resulting in "mis-selection" or "missed selection." To alleviate the shadow problem, some existing devices increase the power of the front light source to enhance the irradiation intensity. However, this not only increases energy consumption but may also cause excessive reflection on the ore surface due to direct strong light, further interfering with the stability of the transmission optical signal. This cannot fundamentally solve the problem of clear signal acquisition from ores with different orientations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an X-ray transmission ore sorting and detection device, comprising: The ore conveying platform has a mounting frame fixedly connected to its top and a uniform irradiation structure set on it. The uniform irradiation structure includes a second mounting base, a positive X-ray detection sensor, and a lamp ring. The second mounting base is bolted to the top of the mounting frame, and the positive X-ray detection sensor is bolted to the inside of the second mounting base. A support frame is fixedly connected to the side of the positive X-ray detection sensor near the mounting frame. The support frame is fixedly connected to the inside of the lamp ring, and the lamp ring is located outside the positive X-ray detection sensor. Fixing seats are fixedly connected to both sides of the ore conveying table. The top of the two fixing seats is bolted to the first mounting base, and the inside of the two first mounting bases is bolted to the second X-ray detection sensor.

[0006] Preferably, the uniform illumination structure further includes two lampshades and two support plates. The two support plates are fixedly connected to the top of the ore conveying platform, and the two lampshades are fixedly connected to the side of the mounting frame near the two support plates. The side of the two lampshades away from the mounting frame is fixedly connected to the corresponding support plate, and lamp tubes are installed inside the two lampshades respectively.

[0007] Preferably, a comb frame is bolted to the top of the ore conveying platform, and multiple comb rods are fixedly connected inside the comb frame.

[0008] Preferably, the lengths of the plurality of comb bars increase sequentially from the ore feed to the ore discharge.

[0009] Preferably, a control panel is fixedly installed on one side of the ore conveying platform.

[0010] Preferably, two reinforcing plates are fixedly connected to the side of the positive X-ray detection sensor near the support frame, and the ends of the two reinforcing plates away from the positive X-ray detection sensor are respectively fixedly connected to the support frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This X-ray transmission ore sorting and detection device has a frontal X-ray detection sensor mounted on the top of the mounting frame via mounting base two. An external lamp ring is fixedly connected to the side of the mounting frame via a support frame, emitting X-rays for frontal transmission detection of the ore. It works in conjunction with side X-ray detection sensors mounted on mounting base one on both sides of the ore conveying platform, emitting X-rays from multiple directions (front and side) to acquire comprehensive transmission information of the ore's interior. Two lamps provide auxiliary illumination; sufficient light makes the ore outline clear, reducing indirect interference from insufficient light on the X-ray detection signal. It also avoids the increased energy consumption and reflection interference problems caused by increasing the power of the frontal light source to alleviate shadows, thus effectively solving the shadow problem, avoiding signal distortion interference, and improving sorting and detection accuracy.
