Technical Field

[0001] The present invention relates to the technical field of building material iron removal, and in particular to a magnetic iron removal device. Background Art

[0002] The presence of iron impurities can affect the quality and performance of building materials. For example, in concrete, iron impurities can cause uneven color of the concrete, affecting its appearance quality. In addition, iron impurities may also affect the mechanical properties of concrete, reducing its strength and durability. Existing iron removal equipment usually installs electromagnets on the conveyor belt to remove iron. In this process, the building material sand is transported through the electromagnet by the conveyor belt, and the electromagnet attracts the iron to achieve iron removal. However, this iron removal method often requires stopping the conveyor belt and cutting off the power supply to the electromagnet to drive the iron to the designated position. After losing magnetism, the iron falls from the electromagnet, completing the iron removal work. Subsequently, the electromagnet needs to be reset and the conveyor belt needs to be restarted to remove iron. The operation is relatively cumbersome, the continuity of the iron removal work is poor, and the overall iron removal efficiency is low. Summary of the Invention

DETAILED DESCRIPTION

[0032] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be understood as a limitation on the scope of protection of the present invention.

[0033] Example 1:

[0034] Reference Figures 1 to 9 The present invention provides a magnetic iron removal device comprising:

[0035] A frame 1, on which a conveyor belt 11 for conveying materials, a conveyor belt 12 for conveying iron, and a flattening mechanism 2 for flattening the materials on the conveyor belt 11 are provided;

[0036] A lifting frame 3 is movably mounted on the frame 1. The frame 1 is provided with a lifting mechanism 13 for driving the lifting frame 3 to move up and down. The lifting frame 3 is provided with a circular track 4, which is mounted on the frame 1. Several sliding frames 5 are movably mounted on the circular track 4. The sliding frames 5 are provided with a partition 51 and a magnetic block 52 that moves vertically relative to the partition 51.

[0037] a driving mechanism 6 , the driving mechanism 6 being disposed on the lifting frame 3 , the driving mechanism 6 being in transmission connection with the plurality of sliding frames 5 and driving the plurality of sliding frames 5 to move along the annular track 4 ;

[0038] The limiting groove 7 is arranged on the lifting frame 3 and is an annular closed structure. The limiting groove 7 is composed of a low and flat section 71, an elevated section 72, a high and flat section 73 and a descending section 74 connected end to end in sequence. The magnetic block 52 is provided with a limiting column 521 that slides with the limiting groove 7. The low and flat section 71 is located above the conveyor belt 11 and is used to drive the magnetic block 52 to be close to the partition 51. The high and flat section 73 is located above the conveyor belt 12 and is used to drive the magnetic block 52 away from the partition 51.

[0039] The material is flattened by the flattening mechanism 2, which can effectively prevent the accumulation of the material, reduce the resistance when the iron is separated from the material, and help improve the iron separation effect. The driving mechanism 6 drives several sliding frames 5 to move along the circular track 4, and cooperates with the conveying process of the conveyor belt 11 and the conveyor belt 12. The special structural design of the limit groove 7 drives the sliding frame 5 to move with the circular track 4. The magnetic block 52 can rise and fall relative to the partition 51 along the path of the limit groove 7. When the sliding frame 5 moves along the low and flat section 71 above the conveyor belt 12, the magnetic block 52 is close to the partition 51, and the iron in the material is attracted to the partition 51. When the sliding frame 5 moves from the low and flat section 71 to the elevated section 72, the magnetic block 52 is relative to the elevated section 72. When the partition 51 is lifted, the sliding frame 5 continues to move from the elevated section 72 to the high and flat section 73 and continues to move along the high and flat section 73. The magnetic block 52 remains away from the partition 51. At this time, the sliding frame 5 moves above the conveyor belt 12, and the iron falls from the partition 51 to the conveyor belt 12 to achieve iron separation. Then, when the sliding frame 5 continues to pass through the descending section 74 from the high and flat section 73, the magnetic block 52 descends relative to the partition 51. When the sliding frame 5 moves from the descending section 74 to the low and flat section 71 and continues to move, the magnetic block 52 remains in close contact with the partition 51 and continues to attract the iron to the partition 51, that is, the transportation and iron removal work are carried out simultaneously, the iron removal work is more continuous, and the overall iron removal work efficiency is high.

[0040] Example 2:

[0041] Reference Figures 1 to 9 Combined with the technical solution of Example 1, in this embodiment, the circular track 4 is composed of a first straight lane 41, a first curve 42, a second straight lane 43 and a third curve connected end to end, the first straight lane 41 is arranged parallel to the conveyor belt 11, and the second straight lane 43 is arranged parallel to the conveyor belt 12.

[0042] Specifically, the elevated road section 72 is composed of a first curved section 721 and a climbing section 722, wherein the first curved section 721 is connected to the low-level road section 71, and the climbing section 722 is connected to the high-level road section 73. The descending road section 74 is composed of a second curved section 741 and a landslide section 742, wherein the second curved section 741 is connected to the high-level road section 73, and the landslide section 742 is connected to the low-level road section 71. The first curved section 721 and the second curved section 741 are aligned with the first bend 42 and the second bend 44, respectively. The second straight road 43 is aligned with both the climbing section 722 and the high-level road section 73. The first straight road 41 is aligned with both the landslide section 742 and the low-level road section 71. The first curved section 721 and the low-level road section 71 are at the same height, and the second curved section 741 and the high-level road section 73 are at the same height.

[0043] When the sliding frame 5 moves along the circular track 4, when the sliding frame 5 slides along the first straight lane 41 and the first curve 42, the magnetic block 52 moves with the landslide section 742, the low and flat section 71 and the first curved section 721, the magnetic block 52 is guided by the landslide section 742 to approach the partition 51, and remains in a state of close contact with the partition 51 when moving to the low and flat section 71, that is, the iron at the conveyor belt 11 is attracted to the partition 51 and moves with the sliding frame 5 to the conveyor belt 12, then the sliding frame 5 slides along the second straight lane 43 and the second curve 44, the magnetic block 52 moves with the climbing section 722, the high and flat section 73 and the second curved section 741, the magnetic block 52 is guided by the climbing section 722 to move away from the partition 51, and remains away from the partition 51 when moving to the high and flat section 73, that is, the suction force of the iron at the second straight lane 43 is reduced and falls to the conveyor belt 12, thereby realizing iron separation.

[0044] Specifically, the conveying speed of the conveyor belt 11 is the same as the moving speed of the sliding frame 5 on the first straight path 41, and the conveying speed of the conveyor belt 12 is the same as the moving speed of the sliding frame on the second straight path 43. The conveying speeds of the conveyor belt 11 and the conveyor belt 12 are the same in magnitude and in opposite directions.

[0045] By controlling the moving speed of the sliding frame 5 to be the same as the size of the conveyor belt 11 and the transport belt 12, the partition 51 and the magnetic block 52 on the sliding frame 5 can attract the iron on the conveyor belt 11 during the synchronous transportation process of the conveyor belt 11, reducing the iron that cannot be sucked away due to the magnetic block 52 quickly sweeping across a certain position relative to the conveyor belt 11, thereby improving the iron removal effect.

[0046] Specifically, the driving mechanism 6 includes a servo motor 61, a first gear 62, an annular chain 63 and a second gear 64. The first gear 62 and the second gear 64 are both rotatably mounted on the lifting frame 3. The annular chain 63 is arranged around the outer periphery of the first gear 62 and the second gear 64 and engages with the two gears respectively. The servo motor 61 is transmission-connected to the first gear 62 and drives the first gear 62 to rotate. The annular chain 63 is respectively connected to several of the sliding frames 5 and drives several of the sliding frames 5 to slide along the annular track 4.

[0047] When the servo motor 61 drives the first gear 62 to rotate, the first gear 62 drives the second gear 64 to rotate through the ring chain 63. At this time, the ring chain 63 drives several sliding frames 5 to move, realizing the sliding process of the sliding frames 5 around the ring track 4.

[0048] Specifically, mounting blocks 8 are rotatably mounted on both ends of the sliding frame 5, and pulleys 81 are rotatably mounted on both ends of the mounting blocks 8. The two pulleys 81 on the same mounting block 8 respectively abut against the inner and outer sides of the annular track 4. The two rotatable mounting blocks 8 and the sliding cooperation between the two pulleys 81 on each mounting block 8 and the track enable the sliding frame 5 to move straight and turn along the annular track 4, ensuring that the sliding frame 5 can slide normally along the annular track 4.

[0049] Example 3:

[0050] Reference Figures 1 to 9 Combining the technical solutions of Example 1 and Example 2, in this embodiment, the lifting mechanism 13 is a hydraulic cylinder, the cylinder body of the hydraulic cylinder is set on the frame 1, and the piston rod of the hydraulic cylinder is connected to the lifting frame 3 and drives the lifting frame 3 to rise and fall.

[0051] The lifting frame 3 is driven to rise and fall by the hydraulic cylinder so as to adjust the height position of the partition 51 at the sliding frame 5 relative to the conveyor belt 11 and the transport belt 12 as needed, thereby ensuring the attraction effect of the magnetic block 52 on iron and improving the iron removal effect.

[0052] Specifically, the flattening mechanism 2 includes a mobile frame 21 and an electric telescopic rod 22. The mobile frame 21 is movably installed on the frame 1 and is not located above the conveyor belt 11. The electric telescopic rod 22 is transmission-connected to the mobile frame 21 and drives the mobile frame 21 to move back and forth.

[0053] The electric telescopic rod 22 drives the mobile frame 21 to reciprocate relative to the conveyor belt 11. During the reciprocating movement of the mobile frame 21, the material on the conveyor belt 11 is flattened, which can effectively prevent material accumulation, reduce the resistance when iron is separated from the material, and help improve the iron separation effect.

[0054] Specifically, the moving direction of the mobile frame 21 is perpendicular to the conveying direction of the conveyor belt 11. The vertical movement of the mobile frame 21 relative to the conveying direction of the conveyor belt 11 is beneficial to cooperate with the conveying process of the conveyor belt 11 to flatten the material more evenly and improve the flattening effect.

[0055] Specifically, a plurality of material shifting plates 211 for leveling the material are arranged in an array on the movable frame 21 .

[0056] The provision of a plurality of material shifting plates 211 is beneficial for increasing the pushing range of the material leveling process and improving the material leveling effect.

[0057] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, use the above technical content to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes.
