For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0020] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Such as Figure 1 、 Figure 2As shown in the figure, this embodiment provides a spliced annular X-ray imaging system, which at least includes: a ray source 1. There are multiple ray sources 1, and the multiple ray sources 1 are arranged in a circumferential direction in a surrounding manner, and two adjacent ray sources 1 in the height direction are arranged with a height offset; the light emitted by each ray source 1 is a fan-shaped light surface at a preset angle, and the fan-shaped light surfaces of all the ray sources 1 are spliced into a 360° annular light surface; a receiving box 2, which is integrally in an annular structure and is arranged on the outer peripheral side of the ray source 1 for receiving the light emitted by the ray source 1. For example, the number of ray sources 1 can be four, six, eight, etc. The specific number can be selected as needed. After the multiple ray sources 1 are spliced in the circumferential direction, they are distributed in an annular shape. All the ray sources 1 irradiate light outward in a direction away from the annular center. For example, half of the ray sources 1 can be located at the same height, and the remaining half of the ray sources 1 are located at another height. The two types of ray sources 1 with different heights are arranged alternately in sequence, so as to prevent all the ray sources 1 from interfering with each other at the same height. Among them, for the receiving box 2, it can be formed by splicing multiple separate receivers along the circumferential direction, and finally form an annular structure. The receiving box 2 can be installed on the inner wall of the frame 13 of the intelligent ore dressing machine through structural parts such as bolts.

[0022] In the spliced annular X-ray imaging system provided by this embodiment, multiple ray sources 1 are arranged in a circumferential direction in a surrounding manner. The light emitted by each ray source 1 is a fan-shaped light surface at a preset angle, and the fan-shaped light surfaces of all the ray sources 1 are spliced into a 360° annular light surface, which can realize 360° dead-angle-free analysis of ores and improve the treatment effect of sorted substances; moreover, two adjacent ray sources 1 in the height direction are arranged with a height offset, which can also optimize the structural layout of the ray sources 1, prevent the ray sources 1 from interfering with each other at the same height, make the best use of the circumferential outer diameter, increase the processing capacity, and improve the processing efficiency.

[0023] For example, there are six ray sources 1, and the fan-shaped light surface formed by each ray source 1 accounts for one-sixth of the entire annular light surface; the first, third, and fifth ray sources 1 among the six ray sources 1 in the clockwise direction have the same height, and the second, fourth, and sixth ray sources 1 have the same height.

[0024] Such as Figure 3 、 Figure 4As shown in the figure, the spliced annular X-ray imaging system further includes an upper cover 3 covering the ray source 1; a plurality of light-transmitting holes 4 are provided on the side wall of the upper cover 3. For example, the light-transmitting holes 4 can be strip-shaped light-transmitting holes 4, and the light-transmitting holes 4 are arranged in one-to-one correspondence with the ray sources 1, so that the light emitted by each ray source 1 can be emitted from the light-transmitting holes 4. For example, the upper cover 3 can be an umbrella-shaped structure as a whole. The top of the upper cover 3 can be a plane, and the side can be an inclined plane. Along the axial direction of the upper cover 3, a plurality of stepped surfaces can be provided on the side wall of the upper cover 3. On the one hand, it can be adapted to the outer shape of the vibrating disk 9 mentioned below, and on the other hand, it is also convenient to open the light-transmitting holes 4 on the side wall.

[0025] Among them, the spliced annular X-ray imaging system further includes an annular support member 5 provided below the upper cover 3. The top of the annular support member 5 is connected to the bottom of the upper cover 3. For example, the annular support member 5 and the upper cover 3 can be connected by bolts. The annular support member 5 and the inner space of the upper cover 3 form a cavity for installing the ray source 1. For example, the annular support member 5 can be installed in the frame 13 of the intelligent ore dressing machine through a structural connector, and the annular support member 5 can support the upper cover 3.

[0026] Among them, the spliced annular X-ray imaging system further includes a first mounting plate 6 arranged horizontally in the cavity. The first mounting plate 6 is connected to the annular support member 5; the emitting end 101 of the ray source 1 is arranged on the first mounting plate 6. For example, the first mounting plate 6 can be a rectangular mounting plate. The first mounting plate 6 can be installed on the inner wall of the annular support member 5 by bolts. Then, the emitting end 101 of the ray source 1 is installed on the upper plate surface of the first mounting plate 6 by bolts.

[0027] Among them, the spliced annular X-ray imaging system further includes a second mounting plate 7 arranged longitudinally in the cavity. The top of the second mounting plate 7 is connected to the bottom of the first mounting plate 6; the control end 102 of the ray source 1 is arranged on the second mounting plate 7. For example, the top of the second mounting plate 7 can be welded to the lower plate surface of the first mounting plate 6, and then the control end 102 of the ray source 1, such as electrical components such as a control box, is installed on the plate surface of the second mounting plate 7 by bolts.

[0028] Among them, the spliced annular X-ray imaging system further includes a beam collimator 8. The beam collimator 8 includes two arc-shaped plates arranged in parallel at intervals. The beam collimator 8 is arranged at the light outlet of the ray source 1, so that the light emitted by the ray source 1 is irradiated in a fan-shaped light surface. For example, the arc-shaped plates can be lead plates, and the interval between the two arc-shaped plates can be adjusted according to needs to ensure that the light is irradiated outward in a fan-shaped light surface after passing through normally.

[0029] As shown in Figure 5 and Figure 6 Another embodiment also provides an intelligent ore dressing machine, which includes the spliced annular X-ray imaging system described in any one of the above, and also includes a machine shell, and the spliced annular X-ray imaging system is arranged in the machine shell.

[0030] As shown in Figure 7 The intelligent ore dressing machine further includes a vibrating disk 9, which is arranged in the machine shell and above the upper cover 3, and the upper cover 3 is used to support the vibrating disk 9; the vibrating disk 9 has a disk-shaped structure, the side wall of the vibrating disk 9 is an inclined surface, and the size of the upper disk surface of the vibrating disk 9 is smaller than that of the lower disk surface; along the axial direction of the vibrating disk 9, several stepped surfaces are arranged on the side wall of the vibrating disk 9, and the ore falls step by step along the stepped surfaces. For example, the outer wall of the vibrating disk 9 can be a horizontal surface, an inclined surface, a vertical surface and an inclined surface from high to low. Such a structural design of the vibrating disk 9 can slow down the falling speed of the ore, making it easier for the spliced annular X-ray imaging system to screen the ore.

[0031] As shown in Figure 8 and Figure 9 The intelligent ore dressing machine further includes an elastic connecting piece 10, which includes an elastic body and plugs 11 protruding from both ends of the elastic body; the elastic connecting piece 10 is arranged between the vibrating disk 9 and the upper cover 3, and sockets 12 adapted to the plugs 11 are arranged on the bottom surface of the vibrating disk 9 and the top surface of the upper cover 3, and the plugs 11 are detachably arranged in the sockets 12. For example, the plug 11 can be a plug pin. The vibrating disk 9 and the upper cover 3 are connected by plugging, which is convenient for assembly and disassembly. The existence of the elastic body allows the vibrating disk 9 to vibrate in the axial direction, facilitating the falling of the ore. Then, the 360° annular light surface formed by the ray source 1 scans the falling ore, and then the light is received by the receiving box 2 and fed back to the analysis and processing system of the intelligent ore dressing machine for subsequent ore screening.

[0032] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
