[0018] 1. Through multi-group sorting units, multiple groups of ore samples from different locations and depths are tested for the content of a certain metal at the same time, so as to speed up the detection of non-ferrous metal content in large areas and multiple levels. And during the detection, the upper loading frame and the lower loading frame of the hemispherical structure are combined to form a spherical grid structure to wrap the ore sample. Then, X-ray excitation and fluorescence detection are performed on the ore sample from both the upper and lower directions at the same time, so that the ore sample can be detected from any height and orientation. Compared with the previous single-angle detection, the detection angle is more three-dimensional and more accurate.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The embodiment of the present invention provides a non-ferrous metal X-ray fluorescence separation and detection device, for example, Figure 1 and Figure 2 As shown, it includes a cleaning loading unit 100 , and a detection frame 200 is provided on one side of the output end of the cleaning loading unit 100 .

[0038] The cleaning and feeding unit 100 is used to clean the outer wall of the non-ferrous metal ore and then automatically feed it in batches.

[0039] A plurality of groups of sorting units 300 are arranged at equal intervals on the top of the detection frame 200 in the horizontal direction.

[0040] A group of detection units 400 is movably installed on the top of each group of the sorting units 300.

[0041] After the non-ferrous metal ore is placed in the detection unit 400, the metal content of the non-ferrous metal ore is detected and separated by X-ray fluorescence method through the sealed cavity formed by the detection unit 400 and the separation unit 300.

[0042] For example, Figure 3 As shown, the cleaning loading unit 100 includes a loading box 110, a loading channel 120 is obliquely arranged in the loading box 110, and a conveying component 130 is arranged at the bottom of the loading channel 120 along its oblique path. A feeding port 121 is arranged at the port of the lower end of the loading channel 120, and a front guide plate 122 is obliquely arranged on the feeding port 121, and the other end of the front guide plate 122 extends along the oblique path to just above the lower end of the conveying component 130.

[0043] Exemplarily, a liquid spraying component 140 is provided just above the conveying component 130, and a lifting cleaning mechanism 150 is provided on the side of the liquid spraying component 140 away from the feeding port 121, and the bottom of the lifting cleaning mechanism 150 is movably attached to the conveying component 130. A feeding port 160 is provided on a side wall of the loading channel 120 close to the detection frame 200, and the feeding port 160 is located just below the end port of the loading channel 120 with a higher height. A loading mechanism 170 is provided in the feeding port 160, and the main body of the loading mechanism 170 is located just below the end port of the conveying component 130 with a higher height, and the loading mechanism 170 as a whole extends horizontally through the feeding port 160 to the outside of the loading box 110.

[0044] For example, Figure 4 As shown, the conveying component 130 includes a conveying belt 131 , and a liquid-permeable mesh belt 132 is provided on the central axis of the conveying belt 131 in the length direction.

[0045] For example, Figure 5As shown, the lifting cleaning mechanism 150 includes a first electric push rod 151, a first motor 152 is installed at the bottom of the first electric push rod 151, and the bottom of the first motor 152 is transmission-connected to a hemispherical cleaning cover 153, the bottom of the cleaning cover 153 is an open structure, and a plurality of groups of cleaning brushes 154 are evenly distributed on the inner wall of the cleaning cover 153, and the end of each group of cleaning brushes 154 away from the inner wall of the cleaning cover 153 faces the central axis of the cleaning cover 153.

[0046] For example, Figure 6 As shown, the feeding mechanism 170 includes a second electric push rod 171 arranged horizontally, a second motor 172 is installed on the output end of the second electric push rod 171, and an extension plate 173 is connected to the end of the second motor 172 away from the second electric push rod 171. A plurality of assembly barrels 174 are arranged at equal intervals in the horizontal direction from one end close to the second motor 172 to the other end on the extension plate 173. The number of the charging barrels 174 is the same as that of the sorting unit 300, and the spacing between two adjacent groups of the charging barrels 174 is the same as that between two adjacent groups of the sorting units 300. A rear guide plate 175 is connected to the top edge of a side wall of the charging barrel 174 close to the conveying component 130, and the height of the end of the rear guide plate 175 away from the charging barrel 174 is higher than the other end.

[0047] First, non-ferrous metal ore is put into the feeding channel 120 through the feeding port 121, and falls onto the conveying component 130 under the action of the front guide plate 122, and is transported to the side of the feeding mechanism 170 by the conveying component 130. When passing under the liquid spraying component 140, the cleaning liquid is sprayed on the surface of the non-ferrous metal ore through it, and then it comes to the bottom of the cleaning cover 153 with the conveying component 130. The cleaning cover 153 is driven to descend and cover the non-ferrous metal ore by the first electric push rod 151, and then the first motor 152 is started, and the cleaning cover 153 is driven to rotate by the first motor 152, so that each group of cleaning brushes 154 cleans the surface of the non-ferrous metal ore in a rotating manner from different directions, cleans the dust and impurities on the surface, avoids cleaning dead corners, reduces the influence of dust and impurities on detection, and thereby improves the accuracy of subsequent detection. And the cleaned sewage will fall through the gap of the permeable mesh belt 132, which is convenient for unified collection.

[0048] After cleaning, the conveying component 130 continues to convey the non-ferrous metal ore to the loading barrel 174 directly below the output port of the conveying component 130. Then the second electric push rod 171 pushes the extension plate 173 to move horizontally, so that the adjacent assembly barrels 174 move to the directly below the output port of the conveying component 130. After all the loading barrels 174 are filled with non-ferrous metal ores, the second electric push rod 171 pushes each assembly barrel 174 to be located obliquely above each corresponding group of sorting units 300, and then the second motor 172 drives each assembly barrel 174 to rotate, so that the non-ferrous metal ores in each assembly barrel 174 can fall into the cavity of each corresponding group of sorting units 300. In this way, automatic cleaning, automatic loading, and automatic batch loading process are realized. Not only the degree of automation of the device is improved, but also the labor intensity is reduced and the efficiency of loading work is improved.

[0049] For example, Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the sorting unit 300 includes a sorting box 310, a top groove 320 of a hemispherical structure is opened at the center of the top of the sorting box 310, and a sorting channel 322 is opened at the bottom of the top groove 320 in the vertical direction. A defective product discharge port 380 is connected to a side wall of the bottom of the sorting channel 322, and the other end of the defective product discharge port 380 extends obliquely downward to the outer wall of the sorting box 310. A finished product discharge port 370 is arranged just above the defective product discharge port 380, and the structure of the finished product discharge port 370 is the same as that of the defective product discharge port 380, and the input end of the finished product discharge port 370 is connected to the sorting channel 322. A sorting solenoid valve 390 is arranged at the junction of the finished product discharge port 370 and the defective product discharge port 380 in the sorting channel 322.

[0050] Exemplarily, a lower loading frame 350 is provided at the center of the top opening of the top trough 320. The lower loading frame 350 is a hemispherical grid structure with an opening at the top. A first ring tube 330 with a circular ring structure is provided on the inner wall of the top trough 320. A plurality of groups of first nozzles 340 are distributed in a circular array on the first ring tube 330. The output ends of the first nozzles 340 are all facing the lower loading frame 350. A rotating rod 360 is installed on one side wall of the lower loading frame 350. The other end of the rotating rod 360 extends horizontally into the cavity of the sorting box 310 and is connected to a third motor 361 in transmission.

[0051] A plurality of groups of first reflective prisms 321 are evenly distributed on the inner wall of the top groove 320 . The first reflective prisms 321 are quadrangular pyramid structures, and the outer walls thereof are all made of mirror material.

[0052] For example, Fig.11As shown, the detection unit 400 includes a mounting frame 410, which is hinged at the top edge of one side of the top groove 320. A hemispherical cover 420 is provided on the mounting frame 410, and the cavity of the hemispherical cover 420 and the cavity of the top groove 320 are combined to form a spherical sealed cavity. An upper loading frame 450 is provided at the center of the bottom opening of the hemispherical cover 420. The structure of the upper loading frame 450 is the same as that of the lower loading frame 350, and the two are movably connected. The upper loading frame 450 and the lower loading frame 350 are combined to form a spherical grid structure.

[0053] Exemplarily, a second annular tube 440 with an annular structure is provided on the inner wall of the hemispherical cover 420 , and a plurality of groups of second nozzles 441 are distributed in an annular array on the second annular tube 440 , and output ends of the second nozzles 441 are all facing the upper loading frame 450 .

[0054] Specifically, a plurality of groups of second reflective prisms 430 are evenly distributed on the inner wall of the hemispherical cover 420, and the structure of the second reflective prisms 430 is the same as that of the first reflective prisms 321. An X-ray emitter is disposed on the inner wall at the top of the hemispherical cover 420 and the inner wall at the bottom of the top groove 320, and a radiation detector is disposed on one side of the X-ray emitter, and the output end of the radiation detector is electrically connected to a metal detection and analysis component.

[0055] After each group of non-ferrous metal ores falls into the lower loading frame 350 in each group of sorting units 300, the installation frame 410 is covered so that the hemispherical cover 420 and the top groove 320 are combined to form a sealed and light-proof cavity, and the lower loading frame 350 and the upper loading frame 450 are mutually engaged to form a spherical grid structure, and the non-ferrous metal ores are wrapped therein. Then, two groups of X-ray emitters are started to excite the atomic nuclei of the non-ferrous metal ores. When the atomic nuclei are excited, a characteristic radiation is emitted, which is called X-fluorescence radiation. Then, the energy and wavelength of the radiation are detected by the radiation detector, and the types of non-ferrous metals are distinguished by different wavelengths.

[0056] After the analysis is completed, the first nozzles 340 and the second nozzles 441 of each group spray cleaning liquid at the same time to remove the radiation on the surface of the ore. Since the output ends of the first nozzles 340 and the second nozzles 441 of each group are respectively directed to the lower loading frame 350 and the upper loading frame 450, the cleaning liquid can act on the ore from all heights and directions, making the cleaning more thorough, so as to facilitate the secondary use and subsequent testing of the ore.

[0057] When it is detected that the required metal content in the ore is greater than the standard, the sorting solenoid valve 390 is closed to allow the ore to flow out through the finished product discharge port 370. When the metal content is less than the standard, the sorting solenoid valve 390 is opened to allow the ore to flow out through the defective product discharge port 380. In this way, automatic detection and automatic sorting are realized, so that the staff can complete the classification of the ore without touching the ore.

[0058] The above embodiments have the following beneficial effects:

[0059] 1. Through the multi-group sorting unit 300, multiple groups of ore samples from different locations and different depths are tested for the content of a certain metal at the same time, so as to speed up the detection of large-area and multi-level non-ferrous metal content. And during the detection, the upper loading frame 450 and the lower loading frame 350 of the hemispherical structure are combined to form a spherical grid structure to wrap the ore sample. Then, the ore sample is simultaneously subjected to X-ray excitation and fluorescence detection from the upper and lower directions, so that the ore sample can be detected from any height and orientation. Compared with the previous single-angle detection, the detection angle is more three-dimensional and more accurate. Then, according to whether the content of a certain metal to be detected meets the standard, it is selected to be discharged through the finished product discharge port 370 or the defective product discharge port 380, so as to realize automatic detection and automatic sorting, and at the same time improve the detection accuracy.

[0060] 2. First, the cleaning liquid is sprayed onto the surface of the non-ferrous metal ore through the liquid spraying component 140, and the first electric push rod 151 drives the cleaning cover 153 to descend and cover the non-ferrous metal ore, and then the first motor 152 drives the cleaning cover 153 to rotate, so that each group of cleaning brushes 154 cleans the surface of the non-ferrous metal ore in a rotating manner from different directions, cleans the dust and impurities on the surface, avoids cleaning dead corners, and reduces the influence of dust and impurities on detection.

[0061] 3. Place the cleaned nonferrous metal ore in each assembly barrel 174 in turn. After all the loading barrels 174 are filled with nonferrous metal ore, the second electric push rod 171 pushes each assembly barrel 174 to be located obliquely above each corresponding group of sorting units 300, and then the second motor 172 drives each assembly barrel 174 to rotate, so that the nonferrous metal ore in each assembly barrel 174 can fall into each corresponding group of lower loading frames 350. In this way, automatic cleaning, automatic loading, and automatic batch loading process are realized. Not only the degree of automation of the device is improved, but also the labor intensity is reduced and the efficiency of loading work is improved.

[0062] 4. After the analysis is completed, the first nozzles 340 and the second nozzles 441 of each group spray cleaning liquid at the same time to remove the radiation on the surface of the ore. Since the output ends of the first nozzles 340 and the second nozzles 441 of each group are respectively directed to the lower loading frame 350 and the upper loading frame 450, the cleaning liquid can act on the ore from all heights and directions, making the cleaning more thorough, so as to facilitate the secondary use and subsequent testing of the ore.
