Description

Technical Field

[0001] The invention belongs to the technical field of magnetic separation, and in particular relates to a high-efficiency high-intensity magnetic separator used for high-intensity magnetic separation of fine-grained seashore sand ore. Background Art

[0002] Most seaside sand mines contain magnetic minerals with different magnetic susceptibility coefficients. Usually, weak magnetic separation is used to separate out the iron minerals with strong magnetism. Then medium magnetic separation equipment is used to separate out most of the titanium iron with strong magnetism and easier to separate. Finally, strong magnetic separation is used for some minerals with weaker magnetism.

[0003] The high-intensity magnetic separator includes a magnetic cylinder, an electromagnet, a feeding device, a sorting tank and a cleaning device for collecting and separating magnetic minerals adsorbed by magnetic force from the magnetic cylinder and non-magnetic minerals not adsorbed.

[0004] Since the fluid flow path in the sorting tank is long and the mineral particles of the coastal fine-grained sand mine are mostly between 0.075mm and 2mm, the smaller particles of minerals have poor fluidity in the sorting tank, causing blockage of the sorting tank and reducing work efficiency.

When the fluid flows into the storage chamber through the water inlet pipe, and the water flow flows into the water outlet pipe through the storage chamber under the guidance of the spirally arranged spring, the diameter of the storage chamber is much larger than the diameter of the water outlet pipe, so the flow rate of the fluid flowing into the water outlet pipe increases; the fluid after the speed increase flows into the nozzle through the expansion chamber, and the inner diameter of the nozzle is smaller than the inner diameter of the expansion chamber; the fluid is ejected through the nozzle at high speed, when the high-speed fluid is ejected through the nozzle; the sprayed fluid is blocked by the annular protrusion and ejected through the rectangular groove body; the sprayed fluid is sprayed at high speed at multiple angles, thereby generating a certain shear force, and using the shear force to break the adhesion between fine magnetic minerals, thereby reducing the aggregation of magnetic minerals; enhancing fluidity, thereby reducing the probability of blockage.

[0094] 3. In practical application, if one group of magnets is damaged, only the damaged magnets need to be replaced. By adding a connecting plate to cooperate with the independently arranged magnets with slots, when one group of magnets is damaged, only the damaged magnets need to be replaced, thereby improving practicality.

[0129] Embodiment 1

[0130] like Figures 1 to 10 As shown, this embodiment provides a high-efficiency high-intensity magnetic separator 100 for high-intensity magnetic separation of fine-grained seashore sand ore, comprising a frame 70 and a sorting box mounted on the frame 70, wherein the inner cavity of the sorting box is hollow, the top is open, and the inlet end is connected to the feed bin 30, through which the raw materials are transported into the sorting box, and the outlet end of the sorting box is connected to the sorting tank 40; the magnetic minerals adsorbed on the magnetic cylinder 20 are stored in the sorting tank;

[0131] The inner cavity of the sorting box is provided with a magnetic cylinder 20, which is driven by the driving system 10. The magnetic cylinder 20 is provided with a roller 60 inside, and a magnetic system 603 is installed on the roller 60. When in use, the driving system 10 is started to drive the roller 60 to rotate.

[0132] Furthermore, a scraper 401 is disposed inside the separation tank 40 and contacts the outer wall of the magnetic cylinder 20 , and the magnetic minerals adsorbed on the magnetic cylinder 20 are scraped off by the scraper 401 .

[0133] In actual application, due to the long flow path of the fluid in the sorting tank and the fact that the mineral particles of the coastal fine-grained sand ore are mostly between 0.075mm and 2mm, the smaller particles of minerals have poor fluidity in the sorting tank, causing the sorting tank to be blocked and reducing work efficiency. In order to solve the above technical problems, please refer to Figures 1 to 10 As shown, a rinsing device 50 is fixedly installed on the inner wall of the sorting box at the position of the sorting tank 40 by fastening screws, and the pipeline of the rinsing device 50 is connected to at least one group of nozzles 501. When in use, the fluid is sprayed out through the nozzles 501.

[0134] An adjustment plate 403 is provided inside the sorting tank 40, and the angle of the adjustment plate 403 is adjusted by the adjustment device 402, so that the adjustment plate 403 is inclined, and the inclination angle is 15°-42°; a mounting member 4025 is provided on the body of the adjustment device 402, and the mounting member 4025 has a groove body for the mounting plate 404 to be inserted, and the fixed connection between the mounting member 4025 and the mounting plate 404 is achieved by tightening screws.

[0135] Furthermore, the mounting plate 404 is welded to the inner wall of the sorting tank 40, and the mounting plate and the sorting tank can be fixedly connected by fastening screws or the like.

[0136] Further, a connecting shaft 4021 is provided on the body of the adjusting device 402, and one end of the connecting shaft 4021 passes through the sorting tank 40 and is connected to a fastener;

[0137] An angle adjustment member 4022 is installed on the connecting shaft 4021 located in the sorting tank 40. The angle adjustment member 4022 arranged on the connecting shaft 4021 can be driven to rotate by rotating the connecting shaft 4021; the angle adjustment member 4022 is provided with a slot 4023 for the adjustment plate 403 to be inserted into, so that the adjustment plate 403 and the slot 4023 are snap-fitted and connected; in actual application, in order to improve the stability between the adjustment plate and the slot, a fixed connection can be made by countersunk bolts or the like.

[0138] In actual application, when the magnetic material is scraped off by the scraper 401 and then enters the sorting tank 40, the liquid sprayed from the nozzle generates a certain impact force, which can effectively reduce the adhesion between fine-grained magnetic minerals and increase the fluidity of the fluid in the sorting tank. The inclined adjustment plate 403 is used to guide the magnetic minerals to move along the inclined path of the adjustment plate 403, thereby reducing the probability of blockage.

[0139] See also Figures 1 to 8As shown, a relatively arranged magnetic system 603 is provided on the roller shaft 60 located in the magnetic cylinder 20, and the magnetic system 603 is composed of a plurality of groups of magnets uniformly distributed radially along the circumference of the connecting disk 601.

[0141] The second end surface of the magnet extends toward the center of the circle and intersects with the center line to form an angle c, which is 15°-45°.

[0142] In practical applications, when the angle β is 4.5° and the angle c is 25°, the magnetic force can reach more than 12,000 gs; the magnetic field force along the circumferential direction is more balanced, and it is easy to adsorb weakly magnetic minerals.

[0143] In actual applications, due to long-term operation, the magnets may be damaged. When the magnets are damaged, the entire magnetic system needs to be removed and cannot be replaced individually. To solve the above technical problems, please refer to Figures 1 to 8 As shown, a connecting plate 601 is fixedly mounted on the roller shaft 60, and the connecting plate 601 is made of high-strength plastic or other materials; a second positioning hole 606 is opened on the connecting plate 601;

[0152] Furthermore, when the spring 6023 is fully compressed, the locking member 6025 disposed on the locking limit ring 6024 passes through the sleeve 6026 and extends into the arc groove disposed in the counterbore 607 to lock the second end.

[0153] In this embodiment, during installation, the slot body of the magnet is tightly attached to the outer wall of the connecting plate 601; then the countersunk bolt 6021 is rotated so that the external thread of the countersunk bolt 6021 is threadedly connected with the internal thread of the first positioning hole 605, and the countersunk bolt 6021 is rotated so that the countersunk bolt 6021 is screwed out of the first positioning hole 605 and enters the second positioning hole 606 and is threadedly connected with the threaded end of the second positioning hole 606;

[0154] When the countersunk bolt 6021 rotates continuously at the threaded end of the second positioning hole 606, it pushes the elastic connector to move in the sleeve; until the locking member 6025 passes through the sleeve 6026 and extends into the arc groove provided in the countersunk hole 607, and locks the second end; the connection between the magnet and the first end 6031 and the second end 6032 is achieved; and at this time, the spring 6023 is fully compressed.

When the locking piece 6025 enters the arc groove, the locking piece recovers so that the locking piece completely fills the arc groove. At this time, the locking piece 6025 is tightly attached to the inner wall of the arc groove.

[0158] Embodiment 2

[0159] In practical applications, the mineral particles of coastal fine-grained sand ore are mostly between 0.075mm and 2mm, which leads to poor fluidity of smaller particles in the sorting tank.

[0164] Furthermore, the diameter of the water outlet pipe 905 is smaller than the diameter of the storage cavity 902 .

[0165] During use, when the fluid flows into the storage chamber 902 through the water inlet pipe 901, and flows into the water outlet pipe 905 through the storage chamber 902, since the diameter of the storage chamber 902 is much larger than the diameter of the water outlet pipe 905, the flow rate of the fluid flowing into the water outlet pipe 905 increases; the accelerated fluid flows into the expansion chamber 906, and the outlet of the expansion chamber 906 is connected to the nozzle 907, the outlet end of the nozzle 907 passes through the shell 908 and extends out of the outside, and the nozzle 907 extending out of the outside is provided with an annular protrusion, and at least one group of rectangular grooves are opened on the annular protrusion, the depth of the rectangular groove is 0.2-0.85mm, and an acute angle of 25° is formed between the end face of the annular protrusion and the bottom end face of the rectangular groove.

[0166] When in use, when the fluid flows into the storage chamber 902 through the water inlet pipe 901, and the water flow flows into the water outlet pipe 905 through the storage chamber 902 under the guidance of the spirally arranged spring 9043, since the diameter of the storage chamber 902 is much larger than the diameter of the water outlet pipe 905, the flow rate of the fluid flowing into the water outlet pipe 905 increases; the accelerated fluid flows into the expansion chamber 906, and flows into the nozzle 907 through the expansion chamber 906, and the inner diameter of the nozzle is smaller than the inner diameter of the expansion chamber 906; therefore, the fluid can be ejected through the nozzle 907 at high speed, when the high-speed fluid is ejected through the nozzle; the sprayed fluid is blocked by the annular protrusion and ejected through the rectangular groove body; the sprayed fluid is sprayed out at high speed at multiple angles, thereby generating a certain shear force, and using the shear force to break the adhesion between fine magnetic minerals, thereby reducing the aggregation of magnetic minerals; enhancing fluidity, thereby reducing the probability of blockage.

[0167] The use process and working principle of the present invention:

[0168] In practical application, when one group of magnets is damaged, only the damaged magnets need to be replaced. When disassembling, the countersunk bolt 6021 is rotated by using a disassembly tool; the countersunk bolt 6021 is screwed out from the second positioning hole 606 and the first positioning hole 605 in turn; the first end 6031 of the contact magnet and the limit between the connecting disk; when the countersunk bolt is screwed out, the limit of the spring 6023 can be released, and the rebound force of the spring 6023 itself can be used to drive the locking member 6025 to automatically pop out of the arc groove, thereby releasing the limit between the connecting disk and the second end 6032, and thus the magnet can be replaced.
