Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the process of sorting ores 100, as shown in fig. 1, the prior art ore identification system mostly includes an X-ray emitter 110 and an X-ray receiver line 120 consisting of a plurality of X-ray receivers. X-ray receiving surface 130 of X-ray receiver linear array 120 receives X-rays 140 emitted by X-ray emitting source 110. In use, X-rays 140 emitted from the X-ray emitting source 110 form a fan-shaped X-ray radiation surface 150, and the X-rays 150 penetrate through the mineral being inspected 100 and then irradiate the X-ray receiving surfaces 130 of the linear X-ray receiver arrays 120. The X-rays 140 received by the X-ray receiving surface 130 vary according to the characteristics of the ore 100, and the ore 100 is identified according to the variation of the X-rays 140. It can be seen that when X-rays 140 are perpendicularly incident on the X-ray receiving face 130, the X-ray receiver linear array 120 has the best receiving effect on the X-rays 140 and the best detection and sorting accuracy.
Referring to fig. 1, since the X-rays 140 penetrate the ore 100 and impinge on the X-ray receiving surface 130, they form an angle with the normal to the X-ray receiving surface 130, which angle affects the formation of an image of the ore 100.
Furthermore, since the closer the ore 100 is to the center line 160 of the X-ray receiving surface, the larger the above-mentioned angle, the shorter the time for the X-ray 140 to reach the X-ray receiving surface 130 after penetrating the ore 100, resulting in the difference in imaging time between the ore 100 far from the center line 160 of the X-ray receiving surface and the ore 100 close to the center line 160 of the X-ray receiving surface, even if the X-ray 140 is transmitted at the same time; further reducing the separation precision, affecting the separation effect and being not beneficial to the separation production of the ore 100.
Example 1
In order to overcome the disadvantage of the prior art ore identification system shown in fig. 1, when the X-ray 140 penetrates the ore 100 and irradiates the X-ray receiving surface 130, an included angle is formed between the X-ray receiving surface 130 and the normal line, and the included angle affects the formation of the image of the ore 100. The present embodiment provides the following ray reception apparatus.
