It provides a drum-type magnetic separation module 10 comprising a.

1 is an embodiment of the drum-type magnetic separation module 10.

Hereinafter, in describing the embodiment of the present invention, the axial direction of the following rotating shaft 20 disposed parallel to the conveying direction of the conveyor belt 3 is referred to as the axial direction of the drum 100, and the axial direction and The orthogonal direction is called the width direction. In addition, the direction in which the first and second side plates 110 and 120 are located in the drum 100 is referred to as a side or a side.

Based on the outer circumferential surface of the drum 100, the inner direction is referred to as an inner or inner end, and the outer direction is referred to as an outer or outer end.

Recycled aggregate is used as recycled aggregate through processes such as crushing, grinding, and vibration sorting of construction waste. Foreign matter (2) may be included.

The conveyor belt 3 may transport the recycled aggregate in which the iron foreign matter 2 and the aggregate 1 are mixed in one direction. The upper surface of the conveyor belt (3) installed in a general recycled aggregate processing plant is U-shaped rather than a smooth surface in order to prevent the recycled aggregate from being separated from the conveyor belt (3) due to vibration, wind, etc. during the transportation process. It was formed and installed to have a cross section of Therefore, as shown in [Fig. 2], the lower end of the drum 100 having a circular cross section corresponding to the cross-sectional shape of the conveyor belt 3 having a U-shaped cross section is close to the upper surface of the conveyor belt 3. Since it is arranged, the upper surface of the conveyor belt 3 and the lower end of the drum 100 can be spaced apart while maintaining a constant interval as a whole. When the magnetic separation part 200 is formed in an arc shape corresponding to the shape of the lower end of the drum 100, the magnetic force is uniformly applied to the upper surface of the conveyor belt 3 formed in a U-shaped cross section in preparation for the case where the sorting part is formed in a smooth surface. can provide.

In the drum 100, a disk-shaped first side plate 110 and a disk-shaped second side plate 120 having an open hole 121 formed on the plate surface are spaced apart from each other on both sides, and the first and second side plates 110, 120) and a drum-shaped frame formed to rotate around the center of the first and second side plates 110 and 120, including a separating surface 140 surrounding the outer periphery.

The first side plate 110 and the second side plate 120 may be formed of disk-shaped members having the same size. Connecting members 130 may be installed at regular intervals to connect the first and second side plates 110 and 120 along the circumferences of the first side plate 110 and the second side plate 120 .

The connecting member 130 may be formed of metal or synthetic resin that is not affected by magnetism, and is particularly preferably formed of austenitic stainless steel that is not affected by magnetism while securing sufficient rigidity.

The connection members 130 may be arranged in parallel at regular intervals, and a separation surface 140 may be inserted and installed therebetween. Alternatively, the separation surface 140 may be fixed to an upper end of the connecting member 130 so that the separation surface 140 is wrapped around and coupled between the first and second side plates 110 and 120 .

At this time, the connection member 130 may be installed at a predetermined interval from the circumference of the first and second side plates 110 and 120 toward the direction of the rotation shaft 20 . When the return blocking plate 150, which will be described later, is manufactured and installed at the same height as the spaced length, the return blocking plate 150 does not protrude outside the circumference of the first and second side plates 110 and 120, so it looks It looks clean and covers the side surface of the return blocking plate 150 to prevent foreign matter from being scattered to the side and preventing the return blocking plate 150 from being jammed or damaged.

The first and second side plates 110 and 120 are formed in a disk shape having a constant thickness, and are provided at both side ends of the drum 100, respectively. Since the first and second side plates 110 and 120 are coupled by a connecting member 130 and continuously rotated by the rotating shaft 20, the first and second side plates 110 and 120 and the connecting member 130 are resistant to torsional moment. In order to prevent deformation and destruction by, it is preferable to be made of high rigidity steel and alloy steel.

The second side plate 120 has an open hole 121 that passes through the inside of the drum 100, and wires, cables, and fixings pass from the outside to the inside of the drum 100 through the open hole 121. A lava member or the like can be drawn in.

The first side plate 110 may be formed as a single disc-shaped body without openings or as a wheel open between spokes. When the first side plate 110 is formed in the shape of a wheel, an end of the rotating shaft 20 may be coupled to the center of the radially extending wheel. Since the first side plate 110 is connected to the rotating shaft 20 and the rotational force of the rotating shaft 20 is transmitted, the central portion where the first side plate 110 and the rotating shaft 20 are coupled is reinforced by adding a reinforcing member or the above Durability may be increased by additionally stacking and bonding a reinforcing plate to the outside or inside of the first side plate 110 .

The separation surface 140 may be formed of at least one of rubber, synthetic resin, synthetic fiber, and metal. Since the separation surface 140 is in direct contact with the iron foreign material 2, it is preferable to be formed of a material that has rigidity and is not magnetized so as not to be worn or damaged by the iron foreign material 2. In addition, since the separation surface 140 forms the outer circumferential surface of the drum 100, a material that can be processed into an arc shape may be applied. Therefore, the separation surface 140 is preferably formed of alloy steel or austenitic stainless steel that has a predetermined strength, is not affected by magnetism, and can be processed and molded into an arc shape.

The separation surface 140 is a curved plate member having a predetermined thickness, and both ends thereof may be coupled to the first and second side plates 110 and 120 to form a ring shape as a whole. The separation surface 140 is preferably formed with a thin thickness so that magnetic force can pass through while satisfying a predetermined strength while minimizing loss.

A support member (not shown) for supporting the separation surface 140 may be further added to the inner end or edge of the separation surface 140 .

The support member is not limited in the arrangement of the support member, such as a lattice type, oblique shape, or a multi-layer type, but is uniformly arranged at regular intervals to stably maintain the shape of the separation surface 140 so that deformation or twisting does not occur. there is.

The support member is preferably made of a metal material that is not affected by magnetic force such as austenitic stainless steel to have sufficient rigidity. In addition, when the support members are continuously arranged in a lattice or linear form, it is preferable to form a gap between the members as wide as possible so as not to hinder the passage of magnetic force.

The magnetic separation unit 200 is disposed spaced apart from the separation surface 140 at the lower part of the inner space of the drum 100, maintains the arrangement state, and provides the magnetic force of the magnet member 210 in a downward direction. The drum 100 may be arranged close to the tangential line of the lower separation surface 140 .

In addition, the magnetic force separation unit 200 accommodates a plurality of magnet members 210, and the plurality of magnet members 210 may be radially and equiangularly arranged from the center point of the first and second side plates 110 and 120. .

As shown in [Fig. 2], the magnetic separation unit 200 is a member that supports the magnet member 210 and the magnet member 210 to be spaced apart from the separation surface 140 and to maintain the arrangement state. It may be composed of a fixing bracket 220 and a case 230.

The magnet member 210 of the magnetic separation unit 200 may be disposed close to each other such that a lower end thereof is parallel to a tangential line of the lower separation surface 140 of the drum 100 . The lower part of the drum 100 is formed in an arc shape corresponding to the shape of the U-shaped conveyor belt 3, and the magnet member 210 is disposed close to and parallel to the tangential line of the lower separation surface 140 of the drum 100 Since the lower end of the magnet member 210 and the separation surface 140 of the lower part of the drum 100 are spaced apart while maintaining a constant distance, magnetic force can be provided uniformly to the upper surface of the conveyor belt 3.

The magnet member 210 may be disposed singly or in plurality in the magnetic separation unit 200 as needed. If the size of the drum 100 cannot deliver sufficient magnetic force with a single magnet member 210, a plurality of magnet members can be arranged, and in order to stably transfer the iron foreign matter 2 to the discharge section, the magnet member 210 until the discharge section. ) can be arranged in multiple numbers.

When a plurality of magnet members 210 are accommodated in the magnetic force separation unit 200, the plurality of magnet members 210 may be radially and conformally arranged from the center point of the first and second side plates 110 and 120.

As shown in [Figure 2], the lower end of the magnet member 210 is radially equiangularly arranged at the center point of the first and second side plates 110 and 120, and the lower end of the magnet member 210 and the drum (100) Since the lower separation surfaces 140 are spaced apart while maintaining a constant interval, magnetic force can be uniformly provided to the upper surface of the conveyor belt 3.

In summary, the magnetic force separation unit 200 provides magnetic force in the downward direction, and more precisely, it is configured to transmit magnetic force uniformly in an arc shape corresponding to the lower shape of the drum 100, and is formed in a U-shaped cross section of the conveyor. Belt 3 can transmit magnetic force uniformly to the upper surface.

As the magnet member 210 of the magnetic force separation unit 200, an electromagnet or a permanent magnet may be selectively applied, or a combination of an electromagnet and a permanent magnet may be applied. The magnet member 210 may be composed of only electromagnets or only permanent magnets, but may be configured so that electromagnets complement permanent magnets or permanent magnets supplement electromagnets as needed.

The magnet member 210 may apply an electromagnet when the intensity of magnetic force needs to be adjusted as needed, and may additionally install a permanent magnet to supplement the electromagnet.

2. Single drum type magnetic separator

As shown in [Fig. 3], the present invention includes 'the drum-type magnetic separation module 10; and a rotating shaft 20 coupled to the center of the first side plate 110 and rotating by externally applied power; Including, the magnetic force provided by the magnetic force separator 200 is applied to the iron foreign matter 2 in the recycled aggregate transported to the conveyor belt 3 through the separation surface 140, the iron foreign matter 2 is the Further provides a single drum-type magnetic separator, characterized in that it is transported along the rotational direction of the drum 100 in a state attached to the separation surface 140 and discharged in a section where the magnetic force is not provided. .

[Figure 3] is an embodiment of the single drum type magnetic separation device of the present invention.

The drum-type magnetic separation module 10 is as described in item 1.

The rotating shaft 20 may be coupled to the center of the first side plate 110 and configured to pivot by externally applied power. The rotary shaft 20 is installed to pivot the drum 100, and is preferably formed of a rod-shaped steel member in order to resist a torsional moment caused by the shaft rotation and increase durability.

Since the drum 100 is spaced apart in the air by the rotating shaft 20 coupled to the first side plate 110, the rotating shaft 20 supports the entire load of the drum 100. At this time, in order to more stably combine the rotary shaft 20 and the first side plate 110, when the rotary shaft 20 is inserted into the drum 100 for a certain length and combined, the rotary shaft 20 is finally inserted into the drum 100. ) can support the load of the drum 100 more stably.

The rotating shaft 20 may further include a power transmission unit 30 that transmits externally applied power.

The power transmission unit 30 may be of a chain type, a belt type, a gear type, etc. to transmit the rotational force generated from the rotary motor.

As shown in [Figs. 8] and [Fig. 9], the chain-type power transmission unit 30 consists of a power transmission sprocket formed along the outer periphery of the rotating shaft 20 and a power transmission chain that transmits rotational force applied from the outside. It can be.

As shown in FIGS. 3 to 5 , the belt-type power transmission unit 30 may be composed of a pulley formed along the outer periphery of the rotation shaft 20 and a power transmission belt. At this time, in order to prevent slipping of the power transmission belt, the contact surface between the pulley and the power transmission belt may increase frictional force or form a groove to prevent slipping.

The gear-type power transmission unit 30 may be composed of a gear blade formed along the outer periphery of the rotating shaft 20 and a gear that transmits rotational force applied from the outside.

The power transmission unit 30 may be installed anywhere in the axial direction of the rotation shaft 20, but it is preferable to install it at the center in order to uniformly transmit rotational force.

In addition, the single drum type magnetic separation device of the present invention may further include a counter weight (80) for applying a load vertically downward to the rotating shaft 20.

Since the drum 100 is installed spaced apart in the air with one end of the rotating shaft 20 coupled to the first side plate 110, it is fixed in a cantilever structure and is not coupled to the rotating shaft 20. A strong bending moment may be applied to the free end (periphery of the second side plate 120). Therefore, when the drum 100 is used for a long time, the entire drum 100 tilts downward due to the weight of the drum 100 and may contact the conveyor belt 3 and be damaged. Therefore, tilting and sagging of the drum 100 can be prevented by adding a counter weight 80 that applies a load vertically downward to the rotating shaft 20 located on the opposite side of the free end.

At this time, the counter weight 80 may have a through hole through which the rotating shaft 20 is inserted. By inserting and fixing the counter weight 80 to the rotation shaft 20, a load can be applied downward to the rotation shaft 20. At this time, the counter weight 80 may be formed in various shapes, and in particular, when the counter weight 80 rotates together with the rotating shaft 20, it is preferable to be formed in a cylindrical shape to prevent eccentric rotation.

In the drum 100 of the present invention, the iron foreign matter 2 is not directly attached to the magnetic separation unit 200, but is adsorbed to the separation surface 140 of the drum 100 and moves for a certain period, and then the magnetic force It falls and is discharged in the section where this is not provided.

In more detail, as shown in [FIG. 2], in the single drum type magnetic separation device, the magnetic force provided from the magnetic separation unit 200 passes through the separation surface 140, and the iron material is transferred to the conveyor belt 3. The iron foreign matter 2 applied to the foreign matter 2 and receiving the magnetic force is transported along the rotational direction of the drum 100 in a state of being adsorbed to the separation surface 140, in a section where the magnetic force is not provided It can be configured to be ejected.

In this case, the iron foreign substance 2 may be attached without being separated from the separation surface 140 due to residual force of magnetic force or static electricity. The drum 100 of the present invention is configured to continuously rotate, and the iron foreign matter 2 is more easily discharged by the centrifugal force generated by the rotation of the drum 100. In addition, when the iron foreign matter 2 falls freely, it may not be accurately seated in the foreign matter outlet (not shown), but in the present invention, the iron foreign matter ( 2) is scattered at a certain height at the same time as discharge and settles in the foreign matter outlet, so foreign matter can be discharged more stably.

The present invention includes a support frame 50 configured to support the rotating shaft 20; It may be configured to further include. Since the drum 100 is coupled to the rotary shaft 20 and supports a load, most of the load is transmitted to the rotary shaft 20 . In addition, since the rotating shaft 20 is connected only to the first side plate 110 of the drum-shaped frame, the drum 100 is coupled to the rotating shaft 20 in a cantilever structure.

The support frame 50 is configured to support the rotating shaft 20 and serves to distribute a load applied to the rotating shaft 20 .

As shown in [Figs. 8] and [Fig. 9], the support frame 50 is a polyhedral frame such as 'ㅁ' or 'c' to stably support along the axial direction of the rotation shaft 20. can be configured.

In this case, the support frame 50 may further include a bearing housing 51 provided at an upper end of the support frame 50 while the rotating shaft 20 is inserted therethrough.

The bearing housing 51 is configured to allow the rotation shaft 20 to rotate smoothly and to support a load so that the bearing mounted therein can maintain a stable state. The bearing may contact along the outer periphery of the rotation shaft 20 to reduce frictional force of the rotation shaft 20 and distribute and support a load applied to the rotation shaft 20 .

One or more bearing housings 51 may be provided at an upper end of the support frame 50 according to a load applied to the rotating shaft 20 .

As shown in [Figure 8] and [Figure 9], the bearing housing 51 prevents deflection and bending of the rotation shaft 20 when provided one by one on both sides of the rotation shaft 20, and stably rotates the rotation shaft 20 ) is preferable because it can support the whole.

Therefore, when the length of the rotating shaft 20 is formed as a long span, bearing housings 51 are installed on both sides and the middle of the rotating shaft 20 to stably support the rotating shaft 20 along the axial direction. can

In addition, the single drum type magnetic separation device has one end fixed to the outside of the drum 100 and the other end introduced into the drum 100 through the open hole 121 of the second side plate 120. cantilever arm 40; Further, the magnetic separation unit 200 includes a fixing bracket 220 installed on the cantilever arm 40; and a case 230 spaced apart from the separation surface 140 by the fixing bracket 220 and accommodating the magnet member 210; It can be configured to include.

The magnetic separator 200 is spaced apart from the inner space of the drum 100 in the air. Therefore, the magnetic separation unit 200 can be stably maintained and fixed in the inner space of the drum 100 regardless of the rotation of the drum 100 by the cantilever arm 40 .

In order to stably support the load of the magnetic separation unit 200, one end of the cantilever arm 40 may be fixed to a stable and highly durable structure such as an external fixed frame, post, or wall.

As shown in [Figs. 2] and [Fig. 6], the lower end of the fixing bracket 220 is formed in an arc shape corresponding to the lower end of the drum 100, and both sides of the support are fixed to the cantilever arm 40. may consist of

The fixing bracket 220 accommodates the magnet member 210 so that the lower end of the magnet member 210 is disposed close to the tangential line of the lower separation surface 140 of the drum 100 .

The magnet member 210 may be composed of a single permanent magnet or electromagnet, and as shown in [Fig. 1] and [Fig. 2], it may be easily transported by providing a hook or handle at the top.

The case 230 accommodates the magnet member 210, and may be applied when the magnet member 210 is composed of a single magnet or a plurality of magnets stacked. In particular, the case 230 can stably accommodate a plurality of permanent magnets when the magnet member 210 is configured by stacking a plurality of permanent magnets.

In addition, in the single drum type magnetic separation device, a permanent magnet is applied as the magnet member 210 of the magnetic separation unit 200, and one or more permanent magnets may be stacked and accommodated in the case 230.

When a permanent magnet is applied as the magnet member 210 of the magnetic separation unit 200, the permanent magnet may be formed by stacking a plurality of permanent magnets in a block shape, as shown in FIG. 6. The number of stacked permanent magnets and the magnetic force are directly proportional to each other. Accordingly, the intensity of magnetic force transmitted from the magnet member 210 may be adjusted by stacking permanent magnets inside the case 230 according to the required magnetic force conditions.

For example, the magnetic force should be configured to decrease from the center of the drum 100 toward the side of the discharge direction so that the iron foreign matter 2 is smoothly separated from the discharge section. It is easy to change the separation and discharge of the iron foreign matter (2).

Therefore, as shown in [Fig. 6], five permanent magnets are stacked on the magnet member 210 at the center, and four permanent magnets are stacked on the magnet member 210 on the side, so that the magnetic force is relatively weak toward the side. The strength of the magnetic force can be adjusted to

In summary, when a permanent magnet is applied to the magnet member 210 of the magnetic force separator 200, one or more permanent magnets may be stacked and accommodated, and the strength of the magnetic force may be adjusted by adjusting the number of stacked permanent magnets. there is.

In addition, on the outer edge of the separation surface 140, a plurality of return blocking plates 150 are provided at equal intervals, the upper end of which is installed in the axial direction to the separation surface 140 and the lower end of which is configured not to touch the conveyor belt 3. It can be. At this time, the return blocking plate 150 may be configured such that an upper end connected to the separation surface 140 is rotatably coupled around the connection part in the axial direction, thereby accelerating the separation of the foreign matter by shaking.

The return blocking plate 150 of the drum 100 may be made of a non-magnetized material such as stainless steel, synthetic resin, or synthetic fiber.

By additionally configuring the return blocking plate 150, foreign substances are prevented from scattering randomly to the outside of the drum 100 by magnetic force, and return by centrifugal force, inertia, and gravity in the discharge section of the iron foreign substances 2. Shaking of the blocking plate 150 helps to discharge the iron foreign matter 2 and contributes to the discharge of the foreign matter by falling to an appropriate position. In addition, the return blocking plate 150 can prevent the iron foreign matter 2 from being returned to the separation surface 140 by static electricity during discharge.

The return blocking plate 150 may be installed as needed. If the iron foreign material 2 is not smoothly attached by the return blocking plate 150 during the attachment process, the return blocking plate 150 may not be installed on the drum 100. Therefore, it is necessary to determine whether or not to install the return blocking plate 150 by comprehensively considering the state of the material and necessity during the use process.

The magnetic separation device of the present invention includes one or more inverters (60) arranged so that the lower end is close to the conveyor belt (3) as a vertical member; Further, the inverter 60 is arranged so as to be orthogonal to the upper surface of the conveyor belt 3, and the lower end collides with the aggregate 1 according to the movement of the conveyor belt 3, thereby changing the phase of the aggregate 1 It can be configured to invert.

The load applied to the drum 100 can be configured to be distributed by installing an auxiliary wheel 70 at the lower part of the second side plate 120, opposite the coupling part between the rotating shaft 20 and the first side plate 110. there is. In addition, the auxiliary wheel 70 may additionally reduce the burden of the load applied to the rotary shaft 20 supporting the load of the drum 100.

As shown in [FIG. 3] and [FIG. 4], the auxiliary wheel 70 may be disposed on the lower front side and rear side of the second side plate 120, respectively. Since this is arranged in a triangular shape when the rotation center of the drum 100 and the auxiliary wheels 70 on both sides are connected to each other, it is preferable to stably distribute the load.

The auxiliary wheel 70 can be applied to any rotational structure capable of engaging with the second side plate 120 and rotating, such as a roller, a gear, or a sprocket.

The auxiliary wheel 70 is not coupled to a separate auxiliary power transmission unit 30, but engages with the rotation of the drum 100 to serve to distribute a load or is coupled to the auxiliary power transmission unit 30 to perform the role of distributing the load. In order to rotate smoothly in engagement with the rotation of the second side plate 120, it may be operated by adjusting the rotation speed according to the rotation ratio.

In addition, the separation surface 140 may be modularized to a certain size and combined.

The size of the module may be determined based on the partition formed between each connecting member 130 .

As described above, when the separation surface 140 is modularized and coupled to the circumference of the drum 100, even if a part of the separation surface 140 is damaged, the entire separation surface 140 is not replaced, and the damaged separation surface 140 ) Only the module can be replaced, so quick replacement is possible, manpower and repair costs are saved, and maintenance is easy.

3. Dual drum type magnetic separator

In the present invention, "the two drum-type magnetic separation modules 10 are spaced apart so that each of the first side plates 110 face each other, and both ends are coupled to the center of the first side plate 110, respectively, A rotating shaft 20 for simultaneously rotating the two drum-type magnetic separation modules 10 by externally applied power; Including, but the magnetic force provided by the magnetic force separator 200 is applied to the iron foreign matter 2 in the recycled aggregate transported to the conveyor belt 3 through the separation surface 140, the iron foreign matter 2 is the A dual-drum magnetic separator, characterized in that it is transported along the rotational direction of the drum 100 in a state attached to the separation surface 140 and discharged in a section where the magnetic force is not provided.” .

In addition, the dual drum type magnetic separation device has one end fixed to the outside of the drum 100 and the other end introduced into the drum 100 through the open hole 121 of the second side plate 120. cantilever arm 40; Further, the magnetic separation unit 200 includes a fixing bracket 220 installed on the cantilever arm 40; and a case 230 spaced apart from the separation surface 140 by the fixing bracket 220 and accommodating the magnet member 210; It can be configured to include.

In addition, in the dual drum type magnetic separation device, a permanent magnet is applied as the magnet member 210 of the magnetic separation unit 200, and one or more permanent magnets may be stacked and accommodated in the case 230.

[Figure 4] is a perspective view of an embodiment of the dual drum type magnetic separation device of the present invention, and [Figure 5] is a dual drum type magnetic separation device in which recycled aggregate continuously passes through two drum type magnetic separation modules 10. In this case, it is a conceptual diagram showing the selection process of the iron foreign matter (2).

Hereinafter, since the configuration of the dual drum type magnetic separation device of the present invention is mostly similar to the single drum type magnetic separation device described above, the differences from the single drum type magnetic separation device will be mainly described to avoid redundant description.

The drum type magnetic separation module 10, the rotating shaft 20, the power transmission unit 30, the cantilever arm 40, the support frame 50, the inverter 60, and the auxiliary wheel described in the single drum type magnetic separation device. (70) and its lower structure are equally applied to the dual drum type magnetic separation device of the present invention, and the difference depending on whether the drum type magnetic separation module 10 is coupled to one end or both sides of the rotating shaft 20 There is a difference that the counter weight 80 is disposed only in a single drum type magnetic separator.

In the dual drum type magnetic separation device of the present invention, two drum type magnetic separation modules 10 are applied, and the rotating shaft 20 of the dual drum type magnetic separation device has each first side plate 110 facing each other. ), and both ends are coupled to the center of the first side plate 110, respectively, so that the two drum-type magnetic separation modules 10 are rotated simultaneously by externally applied power.

In addition, since the dual drum type magnetic separation device of the present invention is coupled to both ends of the rotating shaft 20, each of the two drum type magnetic separation modules 10 formed in the same size and shape, the dual drum type magnetic separation device of the present invention Since the load acts equally on both sides, it has the advantage of not tilting to one side or sagging. Therefore, since the load is evenly distributed on both sides, a separate member for weight distribution such as a counter weight (80) installed in a single drum type magnetic separation device is not required.

In addition, the dual drum type magnetic separation device can simultaneously rotate the two drum type magnetic separation modules 10 with a single power transmission unit 30.

[Fig. 5] is a conceptual diagram showing the sorting process of iron foreign matter 2 when recycled aggregate continuously passes through two drum-type magnetic sorting modules 10 in a dual drum-type magnetic sorting device.

Hereinafter, the process of removing the iron foreign matter 2 in the aggregate 1 by the dual drum type magnetic separation device of the present invention will be described in detail with reference to FIG. 5 .

Hereinafter, the inflow direction based on the transport direction of the recycled aggregate is referred to as the front, and the discharge direction is referred to as the rear.

[Figure 5] shows that when the recycled aggregate is transferred from left to right, the recycled aggregate first passes through the front drum-type magnetic separation module 10, and the iron foreign matter 2 is attached and sorted, and the front drum-type magnetic separation The process in which the iron foreign matter 2 that is not removed from the module 10 passes through the drum-type magnetic separation module 10 at the rear while additional self-separation proceeds is shown in order.

At this time, the iron foreign matter 2 pressed to the lower end of the aggregate 1 may not be separated and removed even by the magnetic force transmitted from the drum-type magnetic separation module 10 by the load of the aggregate 1.

Therefore, the inverter 60 can be installed in any of the separators of the present invention, but is disposed in front of the front drum-type magnetic separation module 10 and between the two drum-type magnetic separation modules 10 in order to increase the sorting efficiency it is desirable

5 in more detail, the recycled aggregate introduced through the conveyor belt 3 passes through the section where the inverter 60 disposed in front of the front drum-type magnetic separation module 10 is installed, while passing through the section where the inverter 60 is installed The phase is reversed by colliding with the lower part of the (60) and bouncing or rolling, and the aggregate (1) and the steel foreign matter (2) are mixed and scattered, so that the steel foreign matter (2) is of the conveyor belt (3) so that magnetic force is easily transmitted. can be moved upwards. After that, the iron foreign matter 2 is primarily separated by the front drum-type magnetic separation module 10, and then the phase of the remaining aggregate 1 is reversed by the inverter 60 to invert the remaining iron foreign matter ( 2) is inverted and arranged in a state where it is easy to receive magnetic force. Thereafter, the iron foreign matter 2 is secondarily separated by the drum-type magnetic separation module 10 at the rear, and the aggregate 1 having a higher selectivity can be discharged.

Summarizing the above, it is possible to sufficiently remove the iron foreign matter (2) with a single drum type magnetic separation device, and the dual drum type magnetic separation device can be applied when the content of the steel foreign matter (2) is high or more precise sorting is required. can

In addition, only by additionally coupling the drum-type magnetic separation module 10 to one end of the rotating shaft 20, it can be easily changed from a single drum-type magnetic separation device to a dual-drum magnetic separation device, so compatibility between devices is excellent.
