Description

Technical Field

[0001] This invention relates to the field of magnetic separation technology, and in particular to an electromagnetic dry powder iron removal machine. Background Technology

[0002] Electromagnetic dry powder iron removal machines are particularly suitable for separating fine-grained mineral particles, such as magnetic fine-grained ferrous metals like hematite, pseudomorphous hematite, limonite, siderite, chromite, and manganese ore; fine-grained non-ferrous metals like wolframite; fine-grained rare metals like monazite; and fine-grained non-metallic minerals like feldspar, quartz, and kaolin. With the development of technology, enterprises have increasingly higher requirements for materials, with a basic requirement of magnetic impurity content of PPM. Therefore, the requirements for magnetic separators are also gradually increasing. The operation process of an electromagnetic dry powder iron removal machine mainly includes: connecting the power supply, starting magnetization, opening the feed valve, and the material passing through the magnetized magnetic mesh. Magnetic impurities are adsorbed onto the magnetic mesh, and the purified material is discharged from the outlet. Closing the feed valve and outlet switch, stopping magnetization, and the magnetic impurities are discharged from the iron discharge port, thus achieving the iron removal effect.

[0003] In the magnetic separation and material discharge processes, existing electromagnetic dry powder iron removal machines introduce impurities. The existing magnetic media mesh structure is fixed with nuts, which risk loosening after a period of operation. When the nuts loosen, vibration causes friction between the magnetic media mesh sheets, leading to magnetic impurities mixed into the material and affecting product quality. The purified material and magnetic impurities are often discharged separately using a separating hopper. This hopper typically employs a flapper structure to control the flow of material and magnetic impurities to two discharge ports. However, during discharge, material and magnetic impurities tend to accumulate above the flapper, flowing to the non-target discharge port when the flapper flips. Furthermore, gaps exist between the flapper mechanism and the main body of the separating hopper, allowing material or magnetic impurities to leak through this area, reducing the quality or yield of the magnetic separation product.

DETAILED DESCRIPTION

[0030] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0031] The embodiments of the present application are described below in conjunction with Figure 1 the drawings.

[0032] The embodiment relates to an electromagnetic dry powder tramp iron remover.

[0033] With reference to Figure 1 The electromagnetic dry powder tramp iron remover in the embodiment comprises a rack 1, a magnetic system device 2, a magnetic separation shell 3, a vibrating motor 4, a locking structure 5, a magnetic medium mesh 6 and a distribution hopper 7. The magnetic system device 2 is arranged on the rack 1. The magnetic separation shell 3 penetrates the magnetic system device 2. The vibrating motor 4 is fixed on the magnetic separation shell 3, and the vibrating motor 4 is located outside the magnetic separation shell 3. The magnetic medium mesh 6 is located in the magnetic separation shell 3. The locking structure 5 is fixed on the magnetic separation shell 3, and the locking structure 5 is used for locking the magnetic medium mesh 6. The locking structure 5 comprises a mesh pressing sleeve 51, a locking nut 52, a mesh rack 53 and an upper pressing assembly 54. The mesh rack 53 is fixed on the magnetic separation shell 3, and the mesh rack 53 is used for sleeving the magnetic medium mesh 6. The mesh pressing sleeve 51 is sleeved on the mesh rack 53, and the mesh pressing sleeve 51 is used for pressing the magnetic medium mesh 6 downwards. The locking nut 52 is threadedly connected with the mesh rack 53, the mesh pressing sleeve 51 is located between the locking nut 52 and the magnetic medium mesh 6, and the locking nut 52 is used for locking the mesh pressing sleeve 51 downwards. The upper pressing assembly 54 is fixed on the upper opening of the magnetic separation shell 3, and the upper pressing assembly 54 is used for pressing the locking nut 52 downwards. The distribution hopper 7 is connected with the lower opening of the magnetic separation shell 3, and the distribution hopper 7 is used for discharging magnetic separation materials and magnetic impurities from different channels.

[0034] Through cooperation of various components of the locking structure 5, the magnetic medium mesh 6 can be stably locked, mutual friction of the magnetic medium mesh 6 in the vibration process is reduced, magnetic impurities mixed into the materials due to the mutual friction of the magnetic medium mesh 6 are reduced, and therefore the quality of material products obtained through magnetic separation of the electromagnetic dry powder tramp iron remover is improved. The mesh pressing sleeve 51 is arranged above the mesh rack 53 and the magnetic medium mesh 6, the magnetic medium mesh 6 is pressed, the locking nut 52 is arranged above the mesh pressing sleeve 51, the mesh pressing sleeve 51 is screwed downwards by the locking nut 52, the upper pressing assembly 54 is fixed on the opening of the magnetic separation shell 3, and the locking nut 52 is pressed downwards. Through pressing of the magnetic medium mesh 6 by multiple components, the magnetic medium mesh 6 can be stably locked through cooperation of the components, and mutual friction of the magnetic medium mesh 6 in the vibration process caused by the vibrating motor 4 is reduced.

[0035] With reference to Figure 2In some embodiments, the upper pressing assembly 54 comprises a stop pressing sleeve 541, a fixing rod 542 and a lower pressing flange 543; the stop pressing sleeve 541 is provided with a downward opening blind hole 5410, the upper end of the net rack 53 is located in the blind hole 5410, and the lower end surface of the stop pressing sleeve 541 abuts against the locking nut 52; the fixing rod 542 has a plurality of fixing rods 542, the fixing rod 542 is fixedly connected with the stop pressing sleeve 541, the lower pressing flange 543 is fixed on the upper opening of the magnetic separation shell 3, and the lower pressing flange 543 presses the fixing rod 542 downward; the lower pressing flange 543 is provided with a downward protruding portion 5431, the protruding portion 5431 has a limiting groove, and the end of the fixing rod 542 away from the net rack 53 is located in the limiting groove.

[0036] By providing the blind hole 5410 in the stop pressing sleeve 541, the stop pressing sleeve 541 can stably stabilize the net rack 53 in the transverse direction, the lower end surface of the stop pressing sleeve 541 abuts against the locking nut 52, and the locking nut 52 is pressed downward to prevent the locking nut 52 from loosening. The lower pressing flange 543 is used to facilitate the stable and convenient fixation of the upper pressing assembly 54 on the upper opening of the magnetic separation shell 3. Therefore, the lower pressing flange 543 can stably press and fix the position of the fixing rod 542, thereby stably pressing the stop pressing sleeve 541, so as to stably lock the magnetic medium mesh 6 and reduce the mutual friction of the magnetic medium mesh 6 in the vibration process. The limiting groove can stably fix the protruding portion 5431, so that the locking structure 5 is more stable. The four fixing rods 542 can be arranged in a "cross" shape, and the design of the four fixing rods 542 in a "cross" shape can stably fix the lower pressing flange 543, the fixing rod 542 and the stop pressing sleeve 541 in sequence, and can also reduce the obstruction to the feed.

[0037] Referring to Figure 2 In some embodiments, the upper end of the stop pressing sleeve 541 decreases in diameter from bottom to top in sequence. The design of the stop pressing sleeve 541 facilitates the guiding and dispersing of the material during feeding, and improves the iron removal efficiency. The upper end of the stop pressing sleeve 541 decreases in diameter from bottom to top in sequence, which reduces the accumulation of the material at the upper end of the stop pressing sleeve 541 and facilitates the feeding operation. Since the magnetic field at the same height center position of the normal magnetic separator is the lowest, the magnetic field is higher at the outer side, and therefore the material in the middle is dispersed outward, which improves the iron removal efficiency.

[0038] Referring to Figure 2In some embodiments, the lower pressing flange 543 is provided with a locking knob 5432 for locking the lower pressing flange 543 with the upper opening of the magnetic separation shell 3. By providing the locking knob 5432, the lower pressing flange 543 is fixed on the upper opening of the magnetic separation shell 3, which is convenient for operation and has a certain adjustment space, so that the downward pressure of the upper pressing assembly 54 is more appropriate, which helps to stabilize the locking of the locking nut 52 and the magnetic medium screen 6.

[0039] Referring to Figure 2 In some embodiments, the electromagnetic dry powder de-ironing machine further comprises a magnetic gathering flange 8, the net rack 53 comprises a net rod 531 and a lower positioner 532, the lower end of the net rod 531 is fixed on the lower positioner 532, the magnetic gathering flange 8 is fixed in the magnetic separation shell 3, and the lower positioner 532 is fixed on the magnetic gathering flange 8. The lower end of the net rod 531 is fixed through the lower positioner 532, which reduces the transverse vibration of the net rod 531 and also facilitates the removal of the net rod 531 and the magnetic medium screen 6. The magnetic gathering flange 8 plays a role in magnetizing and positioning the net rack 53. Specifically, the magnetic gathering flange 8 is welded on the magnetic separation shell 3, which can stably support and position the net rack 53.

[0040] Referring to Figure 1 and Figure 3 In some embodiments, the distribution hopper 7 comprises a distribution shell 71, a cylinder 72, a flap 73, a flap shaft 74, and a plurality of material blocking pieces 75. The distribution shell 71 is provided with a first passage 711, a second passage 712, and a third passage 713. The inlet end of the first passage 711 is in communication with the lower opening of the magnetic separation shell 3, and the second passage 712 and the third passage 713 are respectively in communication with the outlet end of the first passage 711. The cylinder 72 is arranged on the distribution shell 71, the flap shaft 74 is arranged on the distribution shell 71, the flap shaft 74 and the distribution shell 71 can rotate relative to each other, the flap 73 is arranged on the flap shaft 74, the flap 73 is arranged in the first passage 711, the cylinder 72 drives the flap shaft 74 to rotate the flap 73 to swing around the axis of the flap shaft 74, so that the upper end of the flap 73 abuts against the inner wall of the first passage 711 to block the communication between the first passage 711 and the second passage 712 and guide the material or magnetic impurities from the first passage 711 into the third passage 713, or to block the communication between the first passage 711 and the third passage 713 and guide the material or magnetic impurities from the first passage 711 into the second passage 712. The material blocking pieces 75 are arranged above the upper end of the flap 73 in contact with the first passage 711, so that when the upper end of the flap 73 abuts against the inner wall of the first passage 711, the material blocking pieces 75 reduce the material or magnetic impurities falling on the upper end of the flap 73.

[0041] The material blocking piece 75 can prevent the material or magnetic impurities from falling directly above the upper end of the flap 73, reduce the material accumulation on the flap 73, and make the magnetic impurities fall into the target channel of the material after the flap 73 is flipped, thereby improving the quality of the material obtained after the material is separated. In operation, when the material is ready to enter the material separation hopper 7, the cylinder 72 drives the flap 73 to swing against the left side wall, the material enters the first channel 711, and then the material falls into the third channel 713 through the guidance of the flap 73. At this time, due to the effect of the material blocking piece 75, the material is blocked by the material blocking piece 75 and cannot fall onto the upper end of the flap 73, and there is no material accumulation on the upper end of the flap 73, reducing the material falling into the second channel 712. When the magnetic impurities are ready to enter the material separation hopper 7, the cylinder 72 drives the flap 73 to swing against the right side wall, the magnetic impurities enter the first channel 711, and then enter the second channel 712 through the guidance of the flap 73. At this time, due to the effect of the material blocking piece 75, the magnetic impurities are blocked by the material blocking piece 75 and cannot fall onto the upper end of the flap 73, and there is no magnetic impurities accumulation on the upper end of the flap 73, reducing the magnetic impurities falling into the third channel 713. The material can also enter the second channel 712 and the magnetic impurities enter the third channel 713 according to the needs. At this time, due to the effect of the material blocking piece 75, the magnetic impurities can be reduced to enter the second channel 712, and the material can be reduced to enter the third channel 713.

[0042] With reference to Figure 1 In some embodiments, the material blocking piece 75 is an angle iron fixed transversely on the material separation shell 71, and a triangular prism space is formed between the angle iron and the material separation shell 71, and the edges of the triangular prism space are transverse. Using an angle iron as a material blocking piece 75 facilitates the manufacture of the material separation hopper 7 in the electromagnetic dry powder iron remover, and the upwardly inclined surface of the angle iron can reduce the falling of the material or magnetic impurities directly above the upper end of the flap 73, and guide the falling of the material or magnetic impurities, thereby improving the quality of the material obtained after the material is separated.

[0043] With reference to Figure 1 and Figure 4In some embodiments, the upper end of the flap 73 in contact with the first channel 711 is the lower edge of the material blocking piece 75, and both sides of the flap 73 are provided with silica gel scrapers 741 extending out of the upper end of the flap 73. The upper end of the flap 73 in contact with the first channel 711 is the lower edge of the material blocking piece 75, so that the material blocking piece 75 and the flap 73 form a good fit. Since the silica gel scraper 741 is longer than the flap 73, it can better block the sealing effect. When the flap 73 abuts against the material distribution shell 71, the silica gel scraper 741 on one side of the flap 73 can be slightly bent to better abut against the material distribution shell 71. The silica gel scraper 741 on the other side of the flap 73 abuts against the material blocking piece 75, better achieving the sealing effect and reducing the material falling from the gap between the flap 73 and the material distribution shell 71. The scraper can hang the material or magnetic impurities adhering to the material distribution shell 71 of the first channel 711 when switching states, avoiding the influence of the material quality caused by entrainment during the next material falling or slag discharging process. At the same time, the silica gel scrapers 741 on both sides can achieve the purpose of separation. When the cylinder 72 drives the flap 73 to abut against the right side wall, the silica gel scraper 741 on the left side of the flap 73 is on the upper side and in contact with one of the material or magnetic impurities, and the silica gel scraper 741 on the right side of the flap 73 is on the lower side and does not contact the material or magnetic impurities. When the cylinder 72 drives the flap 73 to abut against the left side wall, the silica gel scraper 741 on the right side of the flap 73 is on the upper side and in contact with the other of the material or magnetic impurities, and the silica gel scraper 741 on the left side of the flap 73 is on the lower side and does not contact the material or magnetic impurities, which can improve the quality of the material obtained after distribution.

[0044] With reference to Figure 1 and Figure 5 In some embodiments, the material distribution shell 71 is provided with a sealing strip 76 located between the second channel 712 and the third channel 713 and abutting against the flap shaft 74, for blocking the communication of the second channel 712 and the third channel 713 from below the flap shaft 74. In the prior art, the sealing between the flap shaft 74 and the material distribution shell 71 is not strict, and the material and magnetic impurities can enter the non-target channel from below the flap shaft 74. The sealing strip 76 blocks the communication of the second channel 712 and the third channel 713 from below the flap shaft 74, preventing the material or magnetic impurities from entering the non-target channel from there, and improving the quality or yield of the material obtained after distribution.

[0045] With reference to Figure 1 and Figure 4In some embodiments, the turning plate 73 further comprises a plurality of screws 743 and fixing nuts 744, and a smooth panel 742 is arranged on the side of the turning plate 73 which does not contact the silica gel scraper 741, and a plurality of through holes are arranged on the turning plate 73, the silica gel scraper 741 and the smooth panel 742, the plurality of screws 743 pass through the through holes of the silica gel scraper 741, the smooth panel 742 and the turning plate 73 and are fixed by the fixing nuts 744 to fix the silica gel scraper 741 and the smooth panel 742 on the turning plate 73, and the silica gel scraper 741 extends out of the smooth panel 742 in the direction of the upper end of the turning plate 73. The smooth panel 742 can more stably fix the silica gel scraper 741, and the smooth panel 742 has a relatively smooth surface, which can prevent materials from accumulating on the silica gel scraper 741 and facilitate the falling of the materials or magnetic impurities.

[0046] In addition, the detachable upper cover of the electromagnetic dry powder iron separator can cover the inlet end of the first channel 711, and the detachable upper cover can facilitate the maintenance and replacement of the silica gel scraper 741 and the sealing strip 76. When the parts need to be repaired or replaced, the detachable upper cover can be removed without disassembling the machine body, and the repair and replacement work can be performed.

[0047] The electromagnetic dry powder iron separator can further comprise a discharging sleeve and a dustproof sleeve, the discharging sleeve is used to separate the materials from the detachable upper cover during discharging, and the dustproof sleeve is used to prevent the materials from flying out of the dustproof sleeve and the detachable upper cover during discharging. The materials can directly enter the distribution hopper 7 through the discharging sleeve, avoiding contact with the detachable upper cover and effectively reducing the accumulation of materials on the top of the upper cover. The dustproof sleeve is used to prevent the materials from flying dust. The above structure can reduce cleaning work and improve work efficiency.
