Description

Technical Field

[0001] The invention belongs to the technical field of mining, and in particular relates to mineral processing equipment used in mining nonferrous metal mines. Background Art

[0002] The broad concept of non-ferrous metal minerals refers to all metal minerals except ferrous metal minerals, including heavy metal minerals such as copper, lead, zinc, nickel, cobalt, tungsten, tin, bismuth, molybdenum, antimony, mercury, light metal minerals such as aluminum and magnesium, precious metal minerals such as gold, silver, platinum group, and rare metal minerals.

[0003] The existing technology has the following problems: when mining non-ferrous metal ores, the ore is first crushed and then powdered. Powder processing is convenient for sorting non-ferrous metal ores. Because the metals contained in the powdered metal ore are different, they have different magnetic induction, so they can be sorted by magnetic separation. However, the existing magnetic separation device has a complex structure. On the one hand, it cannot realize the unloading and sorting well. On the other hand, it is not easy to collect and process the metal ore mining materials after sorting (therefore, the existing devices mostly use magnetic separation, and it is not convenient to demagnetize and separate the aggregate after magnetic separation).

The C-shaped conductive sheet 208 inside the outer ring support arm 207 is electrically contacted with the conductive ring 108 on the supporting chassis 106 through the conductive contact head 209.

[0031] In a preferred embodiment, please refer to Figure 8 The magnetic separation arm assembly 300 includes a magnetic separation arm rod 301, a first ball head 302 and a second ball head 305 are fixedly provided at one end of the magnetic separation arm rod 301, and a driven bevel gear 309 is fixedly provided at the other end of the magnetic separation arm rod 301, a first spherical electromagnet 303 is provided in a ball seat slot 306 on the first ball head 302, a second spherical electromagnet 304 is provided in a ball seat slot 306 on the second ball head 305, a plurality of conductive contact arms 308 are fixedly provided on the driven bevel gear 309 through a support rod, a conductive contact head 307 is fixedly provided at the end of the conductive contact arm 308, and the magnetic separation arm rod 301 is connected to the ore dressing plate through a bearing. 201 is rotatably connected, the first ball head 302 and the second ball head 305 rotate in the mineral processing ball tank 202, the main gear driven wheel 112 is meshed with the internal gear drive ring 205, the driven bevel gear 309 is meshed with the bevel gear ring 109, and the multiple conductive contact heads 307 at the ends of the multiple conductive contact arms 308 rotate in the outer ring support arm 207. When the conductive contact heads 307 are in contact with the C-shaped conductive sheet 208, the corresponding first spherical electromagnet 303 and the second spherical electromagnet 304 form a magnetic attraction structure in the first ball head 302 and the second ball head 305, and the magnetic force of the second spherical electromagnet 304 is lower than the magnetic force of the first spherical electromagnet 303.

[0032] In a preferred embodiment, please refer to Fig. 9 The guide plate assembly 400 includes a conical guide plate 401, on which a plurality of guide slides 402 are fixedly arranged, a moving wheel 405 and a contact plate 404 are fixedly arranged on the top of the guide slide 402, and a vibration spring 403 is sleeved on the guide slide 402, the guide slide 402 slides through and through the perforated side plate 111, the vibration spring 403 is located above the perforated side plate 111, and the two ends of the vibration spring 403 respectively contact the perforated side plate 111 and the contact plate 404, and the moving wheel 405 contacts the corrugated lower end surface of the corrugated ring table 204 through the tightening of the vibration spring 403.

[0033] In summary, during the mining and beneficiation of non-ferrous metal ores, the crushed and pulverized ore powder is added into the feed top bin 101 through the feed pipe 102. At this time, the second drive motor 119 is started to drive the spiral feed plate 118, so that the powder material continuously and stably falls from the discharge straight cylinder silo 113 into the guide plate assembly 400. At this time, the first drive motor 110 is started. The first drive motor 110 drives the beneficiation disc assembly 200 to rotate around the discharge straight cylinder silo 113 through the main gear wheel 112 and the inner gear drive ring 205. When the beneficiation disc assembly 200 rotates, the corrugated ring table 204 rotates around the discharge straight cylinder silo 113. Since the moving wheel 405 on the guide plate assembly 400 is always in contact with the corrugated ring table 204 through the vibration spring 403, the moving wheel 405 on the guide plate assembly 400 is always in contact with the corrugated ring table 204 through the vibration spring 403. 04 lower end surface, when the corrugated ring table 204 rotates, the guide plate assembly 400 will form a follow-up vibration structure at the bottom of the discharge straight silo 113, and cooperate with the conical slope of the conical guide plate 401. At this time, when the non-ferrous metal ore powder in the feed top bin 101 passes through the discharge straight silo 113 and falls onto the guide plate assembly 400, through the vibration of the guide plate assembly 400, the non-ferrous metal ore powder will continue to vibrate and slide downward from the conical guide plate 401 stably. At the same time, the present invention stably feeds material into the discharge straight silo 113 through the spiral conveying plate 118, which will not cause a sudden increase in material and cause it to accumulate on the guide plate assembly 400, thereby ensuring that the guide plate assembly 400 effectively and steadily guides and disperses the material by vibration.

[0034] On the basis of the above, that is, on the basis of the follow-up vibration-type material guide and bulk material of the guide plate assembly 400, the non-ferrous metal ore powder is distributed on the guide plate assembly 400. When the ore dressing plate assembly 200 rotates, the multiple magnetic separation arm assemblies 300 inside the ore dressing plate assembly 200 rotate around the discharge straight cylinder silo 113. At this time, the driven bevel gear 309 on the magnetic separation arm assembly 300 meshes and moves on the conical gear ring 109, that is, the magnetic separation arm assembly 300 forms a follow-up self-rotation structure in the ore dressing plate assembly 200, that is, when the magnetic separation arm assembly 300 rotates around the discharge straight cylinder silo 113, it also forms a self-rotation structure. When the magnetic separation arm assembly 300 rotates around the discharge straight cylinder silo 113, the first spherical electromagnet 303 and the second spherical electromagnet 304 on the first ball head 302 and the second ball head 305 are energized and form a magnetic attraction structure, through the first The circumferential magnetic attraction of a spherical electromagnet 303 and a second spherical electromagnet 304 magnetically separates the non-ferrous metal ore powder on the guide plate assembly 400. When the magnetic separation arm assembly 300 rotates, the first ball head 302 and the second ball head 305 rotate in the mineral processing ball trough 202, so that the ball seat slot 306 changes direction and gradually faces the connecting silo 116. At this time, the first spherical electromagnet 303 and the second spherical electromagnet 304 in the first ball head 302 and the second ball head 305 are powered off, that is, they lose their magnetic force. At this time, the ball seat slot 306 rotates to a direction facing the connecting silo 116, and the connecting silo 116 is connected to an external negative pressure collection device (the external negative pressure collection device is a known technology, so it is not repeated here), and the non-ferrous metal ore powder in the first spherical electromagnet 303 and the second spherical electromagnet 304 are collected and separated by the external negative pressure collection device.

[0035] On the basis of the above, in order to facilitate the first spherical electromagnet 303 and the second spherical electromagnet 304 to be energized and magnetic and to lose magnetism when powered on and powered off when rotating on the mineral processing disk assembly 200, a plurality of conductive contact arms 308 are provided at one end of the driven bevel gear 309 of the present invention through a support rod (the conductive contact arms 308 are elastic contact rods, which are prior art and will not be described in detail). The number of the conductive contact arms 308 corresponds to the number of the first spherical electromagnets 303. When the magnetic separation arm assembly 300 rotates on the mineral processing disk assembly 200, the plurality of conductive contact heads 307 on the top of the plurality of conductive contact arms 308 rotate in the outer ring support arm 207. When the first spherical electromagnet 303 and the second spherical electromagnet 304 face downward, the corresponding conductive contact arms 308 The conductive contact head 307 is in electrical contact with the C-type conductive sheet 208, and the C-type conductive sheet 208 is in electrical contact with the conductive ring 108 through the conductive contact head 209. At this time, the first spherical electromagnet 303 and the second spherical electromagnet 304 are energized and magnetic, thereby realizing magnetic attraction and separation of non-ferrous metal ore powder. When the first spherical electromagnet 303 and the second spherical electromagnet 304 are facing upward, the conductive contact head 307 on the corresponding conductive contact arm 308 is in contact with the notch of the C-type conductive sheet 208. At this time, the first spherical electromagnet 303 and the second spherical electromagnet 304 are powered off and lost magnetism, thereby facilitating the external negative pressure collection device to extract the non-ferrous metal ore powder in the first spherical electromagnet 303 and the second spherical electromagnet 304 through the connecting silo 116.

[0036] On the basis of the above, in order to realize the sorting of non-ferrous metal ore powder, that is, the sorting of the material that is vibrated and slid down and dispersed on the guide plate assembly 400, the first spherical electromagnet 303 and the second spherical electromagnet 304 of the present invention respectively carry different currents. Specifically, the second spherical electromagnet 304 has a small magnetic force, and the first spherical electromagnet 303 has a large magnetic force. That is, when the non-ferrous metal ore powder is vibrated and slid down and vibrated and dispersed on the guide plate assembly 400, the second spherical electromagnet 304 with a small magnetic force first sorts the ore with a high metal content. Magnetic separation, and then the first spherical electromagnet 303 with large magnetic force is used to magnetically separate the ore with low metal content. In this way, the separation of non-ferrous metal ore powder can be achieved. At the same time, the magnetic force of the first spherical electromagnet 303 and the second spherical electromagnet 304 of the present invention is controlled by electric current. When the present invention is actually used, the first spherical electromagnet 303 and the second spherical electromagnet 304 are arranged on the same circuit, and a resistor is set to control the specific current size through the resistor (the resistor controlling the current size is a known technology, so it is not repeated).

[0037] In another embodiment of the present invention, the volume of the conical guide plate 401 is set to be larger. In this case, the magnetic separation arm 301 is provided with more first ball heads 302 and second ball heads 305, and more spherical electromagnets with different magnetic force levels are arranged inside. In this way, the non-ferrous metal ore powder material can be further magnetically graded.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
