Description

Technical Field

[0001] This utility model relates to the field of waste metal sorting technology, and in particular to a pneumatic mechanism for an eddy current separator. Background Technology

[0002] Eddy current separators are devices that use the principle of electromagnetic induction for sorting. Their working principle is based on the conductivity of metals, generating eddy currents, and then separating the metals through changes in the magnetic field. This equipment is widely used in scrap metal recycling, mineral processing, and metallurgy. The working principle of eddy current separators is based on two important physical phenomena: an alternating magnetic field that varies with time always produces an alternating electric field (the law of electromagnetic induction); and a current-carrying conductor generating a magnetic field (Biot-Savart law). During operation, a high-frequency alternating strong magnetic field is generated on the surface of the sorting magnetic roller. When conductive non-ferrous metals pass through the magnetic field, eddy currents are induced within them. These eddy currents themselves generate a magnetic field in the opposite direction to the original magnetic field. The non-ferrous metals (such as copper and aluminum) are then propelled forward along their conveying direction by the repulsive force of the magnetic field, achieving separation from other non-metallic materials and thus achieving the purpose of sorting.

[0003] However, existing equipment often encounters the following problems during use:

[0004] Traditional eddy current separators have their guide plates fixed to the frame, which cannot be adjusted according to the size of the material, resulting in inconsistent sorting effects for materials of different sizes. Utility Model Content

[0005] The main objective of this invention is to provide a pneumatic mechanism for an eddy current separator, which effectively solves the problem mentioned in the background art that the guide plate of the existing traditional eddy current separator is fixedly installed as an integral part of the frame and cannot be adaptively adjusted according to the size of the material.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pneumatic mechanism for an eddy current separator includes:

[0008] Eddy current conveyor belt;

[0009] A guide plate, wherein the guide plate is disposed in the extending direction of the output end of the eddy current conveyor belt.

[0010] A plastic storage box, located directly below the drainage plate;

[0011] A metal storage shell, wherein the metal storage shell is located in the flow guiding direction of the flow guiding plate;

[0012] A lifting mechanism is disposed inside the plastic storage box;

[0013] An adjusting mechanism is provided, which is connected to the lifting mechanism, and is used to adjust the horizontal distance between the guide plate and the output end of the eddy current conveyor belt.

[0014] The lifting mechanism also includes:

[0015] A fixing component, one side of which is fixedly connected to the non-draining surface of the drainage plate;

[0016] A transverse fixing rod, which passes through the fixing member;

[0017] A support shell is fixedly mounted inside the plastic storage box;

[0018] A lifting cylinder, which is fixedly installed on the inner wall of the support shell;

[0019] A linkage beam is horizontally positioned at the output end of the lifting cylinder.

[0020] Lifting guide rods, at least two of which are arranged side by side on the top surface of the linkage beam, with the top end of each lifting guide rod passing through the inner wall of the top of the support shell;

[0021] A longitudinal slide rail, the back of which is fixed to one end of the transverse fixing rod.

[0022] The distance adjustment mechanism further includes:

[0023] An adjusting cylinder is longitudinally disposed inside the plastic storage box, and the output end of the adjusting cylinder is connected to the bottom end of the vertical rotating shaft.

[0024] The top end of the vertical rotating shaft slides into contact with the longitudinal slide rail;

[0025] The vertical rotating shaft has a pivot at its bend, allowing it to be rotatably mounted on the frame.

[0026] A tie rod, one end of which is fixedly connected to the other side of the fixing member, and the other end of which is horizontally inserted through the guide member;

[0027] A guide member is fixedly connected to the top end of the lifting guide rod.

[0028] The vertical pivot is L-shaped.

[0029] The adjustable gap mechanism adjusts the horizontal gap between the guide plate and the output end of the eddy current conveyor belt to adapt to the sorting requirements of materials of different sizes.

[0030] The engagement between the pull rod and the guide allows the pull rod to slide linearly within the guide to adjust the horizontal position of the diversion plate, while also allowing the pull rod to rise and fall as a whole with the guide.

[0031] The movement trajectory of the top of the vertical rotating shaft is arc-shaped. Through the connection between the longitudinal slide rail and the transverse fixed rod, the arc motion is converted into a horizontal linear motion that drives the fixing component and the diversion plate.

[0032] Compared with the prior art, the beneficial effects of this utility model are: when the adjustable cylinder designed in this utility model is activated, it drives the vertical rotating shaft to rotate around the shaft. Its top end pushes the horizontal fixing rod and fixing parts through the longitudinal slide rail, thereby driving the guide plate to move closer to or away from the output end of the eddy current conveyor belt. After the horizontal distance between the guide plate and the eddy current conveyor belt is adjusted, it can adapt to materials of different sizes to ensure the sorting quality of different sizes.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] like Figure 1-4 As shown, this utility model provides a pneumatic mechanism for an eddy current separator. The pneumatic mechanism of the eddy current separator includes an eddy current conveyor belt 1, a diversion plate 2, a plastic storage box 3, a metal storage shell 4, a lifting mechanism 5, and a distance adjustment mechanism 6.

[0042] The guide plate 2 is positioned along the extension direction of the output end of the eddy current conveyor belt 1. Its function is to guide different materials to different storage locations based on their properties, such as magnetic or non-magnetic characteristics. Its placement along the extension direction of the output end of the eddy current conveyor belt 1 is to control the flow direction of the materials according to their physical properties, ensuring effective separation of metals and plastics. The plastic storage box 3 is located directly below the guide plate 2, and the metal storage shell 4 is located in the guiding direction of the guide plate 2. These two storage units are designed to store plastic and metal materials respectively. The plastic storage box 3, located below the guide plate 2, ensures that plastic materials not attracted by magnetic force ultimately enter this box; while the metal storage shell 4, located in the guiding direction of the guide plate 2, is used to collect the metal materials guided by the guide plate 2.

[0043] In this invention, the lifting mechanism 5 is housed within the plastic storage box 3. The lifting mechanism 5 controls the raising and lowering of the guide plate 2 via a lifting cylinder 54, adapting it to the size requirements of different materials. The lifting function dynamically adjusts the gap between the guide plate 2 and the eddy current conveyor belt 1 according to the characteristics of the material, thereby optimizing the sorting effect. If the material size is small and the centrifugal force is large, the lifting mechanism 5 can raise the guide plate 2 to prevent the material from being thrown out, ensuring stability and accuracy during the sorting process.

[0044] In this invention, the adjusting mechanism 6 is connected to the lifting mechanism 5. The adjusting mechanism 6 is used to adjust the horizontal distance between the guide plate 2 and the output end of the eddy current conveyor belt 1. The adjusting mechanism 6 is used to adjust the horizontal distance between the guide plate 2 and the eddy current conveyor belt 1 to adapt to materials of different sizes. This design allows the equipment to make fine adjustments when facing different material types, improving the flexibility and applicability of sorting.

[0045] In this utility model, the lifting mechanism 5 further includes: one side of the fixing member 51 is fixedly connected to the non-drained surface of the diversion plate 2; the design of the fixing member 51 and the transverse fixing rod 52 ensures the stability of the diversion plate 2 during operation, so that the diversion plate 2 can accurately cooperate with other components such as the lifting mechanism 5, avoiding the impact of vibration or displacement on the sorting effect; the transverse fixing rod 52 passes through the fixing member 51; the support shell 53 is fixedly mounted in the plastic storage box 3; the lifting cylinder 54 is fixedly mounted on the inner wall of the support shell 53; the linkage beam 55 is transversely mounted at the output end of the lifting cylinder 54; at least two lifting guide rods 56 are arranged side by side on the top surface of the linkage beam 55; the top end of the lifting guide rod 56 passes through the top inner wall of the support shell 53; the design of the lifting guide rod 56 and the linkage beam 55 makes the lifting process of the diversion plate 2 stable and accurate. Under the guidance of the inner wall of the support shell 53, the lifting guide rod 56 can ensure the straightness of the lifting process and prevent the diversion plate 2 from shifting due to unstable lifting, which would affect the sorting effect. The back of the longitudinal slide rail 57 is fixed to one end of the transverse fixing rod 52.

[0046] In this invention, the adjusting mechanism 6 adjusts the horizontal distance between the guide plate 2 and the output end of the eddy current conveyor belt 1 to adapt to the sorting requirements of materials of different sizes. The adjusting mechanism 6 includes: an adjusting cylinder 7 longitudinally arranged in the plastic storage box 3, the output end of the adjusting cylinder 7 being connected to the bottom end of the vertical rotating shaft 8; the vertical rotating shaft 8 is L-shaped, and the top end of the vertical rotating shaft 8 is slidably engaged with the longitudinal slide rail 57; the movement trajectory of the top end of the vertical rotating shaft 8 is arc-shaped, which is converted into horizontal linear motion of the driving fixing part 51 and the guide plate 2 through the connection between the longitudinal slide rail 57 and the transverse fixing rod 52; the turning part of the vertical rotating shaft 8 is provided with a rotating shaft 9, so that the vertical rotating shaft 8 can be rotatably installed on the frame; the setting of the rotating shaft 9 and the vertical rotating shaft 8 allows the top end of the vertical rotating shaft 8 to slide smoothly during the lifting process, avoiding the inability of the guide plate 2 to accurately align due to positional deviation, and ensuring the smooth progress of the sorting process.

[0047] One end of the pull rod 10 is fixedly connected to the other side of the fixing member 51, and the other end of the pull rod 10 is horizontally inserted into the guide member 11. The cooperation between the pull rod 10 and the guide member 11 allows the pull rod 10 to slide linearly within the guide member 11 to adjust the horizontal position of the diversion plate 2. Simultaneously, it allows the pull rod 10 to rise and fall as a whole with the guide member 11. Through its cooperation with the guide member 11, the pull rod 10 enables precise adjustment of the position of the diversion plate 2. During material sorting, the rising and falling of the pull rod 10 ensures that the position of the diversion plate 2 can be adjusted, thereby adapting to the sorting requirements of different materials and enhancing the flexibility of the system. The guide member 11 is fixedly connected to the top end of the lifting guide rod 56.

[0048] If the material to be separated by the eddy current separator is too small, the material, whether metal or plastic, will be thrown a long distance due to the large centrifugal force, resulting in an unsatisfactory separation effect. In this case, the lifting cylinder 54 is activated. The output end of the lifting cylinder 54 pops out and lifts the linkage beam 55. The linkage beam 55 rises and lifts the lifting guide rod 56 fixedly connected above. Guided by the inner wall of the support shell 53, the lifting guide rod 56 rises linearly. The top of the lifting guide rod 56 will drive the fixed guide member 11 to rise. The rise of the guide member 11 means that the tension rod 10 passing through the guide member 11 rises. Finally, the tension rod 10 drives the fixed member 51 and the diversion plate 2 to rise. During the rise, the rise of the slide rail will cause the top of the vertical rotating shaft 8 to slide and engage. After the rise, the diversion plate 2 will be higher than the eddy current conveyor belt 1. The higher diversion plate 2 will cause the conveyed material to be blocked by the plate and fall down to complete the separation. For example, small non-ferrous metals will be thrown further by the repulsive force of the magnetic force and the centrifugal force, thus overcoming the obstruction of the guide plate 2 and being guided into the metal storage shell 4 below by the guide surface of the guide plate 2. Plastics, which do not have a magnetic field reaction, are thrown with less force and are blocked by the guide plate 2, entering the gap between the guide plate 2 and the conveyor belt, and reaching the plastic storage box 3 below, thus completing effective sorting.

[0049] It should be noted that, in the pneumatic mechanism of the eddy current separator designed in this utility model, when materials of different sizes are placed on the eddy current conveyor belt 1, the distance between the guide plate 2 and the output end of the conveyor belt can be adjusted according to the metal size of the material to be separated. The adjusting cylinder 7 is then activated, and its output end pops out to push the bottom end of the vertical rotating shaft 8. The bottom end of the vertical rotating shaft 8 rises and rotates around the rotating shaft 9 at its turning point. The top end of the vertical rotating shaft 8 then pushes the longitudinal slide rail 57 forward, which in turn drives a transverse fixing rod on one side. At one end of 52, the fixing member 51 on the body of the transverse fixing rod 52 will be driven together, and the tension rod 10 on one side of the fixing member 51 will gradually move towards the conveyor belt. The tension rod 10 slides linearly in the guide member 11, which means that the guide plate 2 on the other side of the fixing member 51 will gradually approach the conveyor belt, and eventually reduce the gap between the guide plate 2 and the conveyor belt. In this way, when the material conveyed by the eddy current conveyor belt 1 is sorted, it can be sorted into materials of appropriate size, and there will be no situation where the size of the sorted material is too large to pass through the gap and enter the plastic storage box 3.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
