Description

Technical Field

[0001] This utility model relates to the technical field of scrap steel recycling equipment, specifically a magnetic separation device for scrap steel recycling. Background Technology

[0002] my country is currently the world's largest steel producer and also the world's largest market for scrap steel. At present, scrap steel recycling mostly involves the following processes: crushing, washing, magnetic separation, and compression. Magnetic separation is a processing method that uses the differences in magnetic properties of various substances in solid waste to separate the waste materials.

[0003] Existing recycling devices often suffer from damage to their inner walls due to scrap steel impacting the inner walls during operation, which can significantly impact the lifespan of the entire device. Therefore, there is an urgent market need to develop a magnetic separation device for scrap steel recycling to help solve this problem.

[0004] Currently, most existing magnetic separation devices for scrap steel recycling use electromagnets or permanent magnets installed inside the equipment to attract scrap steel. During use, scrap steel slag and scrap slag are fed together through the feed inlet of the equipment, and magnetic force is used to attract and separate the scrap steel from the scrap slag. However, since the electromagnets or permanent magnets remain stationary inside the equipment, the incoming scrap slag and scrap steel slag tend to accumulate together, often resulting in the scrap steel slag encased inside the scrap slag not being attracted, leading to poor separation effect. Therefore, we propose a magnetic separation device for scrap steel recycling. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic separation device for scrap steel recycling, which has the advantages of dispersing and recycling and good recycling effect. It solves the problem that most existing magnetic separation devices for scrap steel recycling use electromagnets or permanent magnets installed inside the equipment to attract scrap steel. In use, scrap steel slag and scrap slag are added together from the feed port of the equipment, and magnetic force is used to attract and separate the scrap steel in the scrap slag. However, since the electromagnets or permanent magnets remain stationary inside the equipment, the incoming scrap slag and scrap steel slag tend to accumulate together, which often leads to the scrap steel slag inside the scrap slag not being attracted, resulting in poor separation effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetic separation device for scrap steel recycling, comprising a magnetic separation cylinder, and further comprising:

[0007] Guide rail seats are fixedly installed on the left and right sides of the inner cavity of the magnetic separator. A left limiting disk and a right limiting disk are respectively provided at the left and right ends of the inner cavity of the magnetic separator. Guide rail rings that slide in the guide rail seats are fixedly connected to the right side of the right limiting disk and the left side of the left limiting disk. Multiple electromagnetic rods are provided on the inner side of the left limiting disk and the right limiting disk, and a barrier sleeve is provided on the outer side of the electromagnetic rods.

[0008] A drive motor is fixedly installed at the middle of the left side of the magnetic separator, and the output end of the drive motor is fixedly connected to the middle of the left limiting disk. A discharge trough is provided at the bottom of the magnetic separator.

[0009] Preferably, the magnetic separator is provided with a feed inlet at the top.

[0010] Preferably, an auxiliary shaft is movably connected to the right side of the magnetic separator via a bearing, and the left side of the auxiliary shaft is fixedly connected to the right side of the right limiting disc. A first sprocket is fixedly installed on the right side of the auxiliary shaft.

[0011] Preferably, a support base is fixedly installed at the bottom of the magnetic separator, and a rotating shaft is movably connected to the upper end of the inner cavity of the support base through a bearing. A second sprocket is fixedly installed on the right side of the rotating shaft, and the outer diameter of the second sprocket is larger than that of the first sprocket. A chain is sleeved on the outer side of the first sprocket and the second sprocket.

[0012] Preferably, an arc-shaped guide groove is provided at the lower end of the discharge trough, and an arc-shaped sealing plate is slidably connected to the inner side of the arc-shaped guide groove. Arc-shaped seats are fixedly connected to the left and right ends of the bottom of the arc-shaped sealing plate. Arc-shaped toothed plates are fixedly installed at the top and bottom of the inner side of the arc-shaped seats. Half gears that mesh with the arc-shaped toothed plates are fixedly installed at the left and right ends of the outer surface of the rotating shaft.

[0013] Preferably, a collection box is provided at the bottom of the inner side of the support base, and handles are fixedly installed on both the front and rear sides of the collection box, and a triangular partition block is fixedly installed at the bottom of the inner cavity of the collection box.

[0014] Preferably, an n-shaped shielding seat is fixedly installed at the middle of the bottom of the arc-shaped sealing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. When waste residue and waste steel slag are fed into the magnetic separator through the feed inlet, the external controller turns on the drive motor. With the assistance of the auxiliary shaft, guide rail seat and guide rail ring, the drive motor can smoothly drive the left and right limiting disks to rotate. The synchronously rotating left and right limiting disks can drive the energized electromagnetic rod to rotate. With the help of the barrier sleeve set outside the electromagnetic rod, the waste residue and waste steel slag fed into the feed inlet can be dispersed, avoiding accumulation.

[0017] 2. This utility model uses an energized electromagnetic rod to adsorb the dispersed waste steel slag onto the outside of the barrier sleeve. Simultaneously, the electromagnetic rod and barrier sleeve, which rotate with the left and right limiting discs, can further disperse the waste slag and waste steel slag that fall into the lower part of the magnetic separator, thereby further adsorbing the waste steel slag. After the waste steel slag is discharged through the discharge chute, the external controller cuts off the power to the electromagnetic rod, allowing the waste steel slag adsorbed on the outside of the barrier sleeve to be discharged through the discharge chute after the waste slag is discharged, making it convenient for users.

[0028] Example 1

[0029] Please see Figures 1-5 As shown, this utility model provides a technical solution: a magnetic separation device for scrap steel recycling, including a magnetic separation cylinder 1, and further comprising:

[0030] Guide rail seats 103 are fixedly installed on the left and right sides of the inner cavity of the magnetic separator 1. A left limiting disk 110 and a right limiting disk 113 are respectively provided at the left and right ends of the inner cavity of the magnetic separator 1. Guide rail rings 109 that slide in the guide rail seats 103 are fixedly connected to the right side of the right limiting disk 113 and the left side of the left limiting disk 110. Multiple electromagnetic rods 112 distributed at equal angles are provided on the inner side of the left limiting disk 110 and the right limiting disk 113. A blocking sleeve 111 is sleeved on the outer side of the electromagnetic rods 112.

[0031] A drive motor 102 is fixedly installed at the middle of the left side of the magnetic separator 1, and the output end of the drive motor 102 is fixedly connected to the middle of the left limiting disk 110. A discharge trough 108 is provided at the bottom of the magnetic separator 1.

[0032] The magnetic separator 1 is provided with a feed inlet 101 at the top.

[0033] This technical solution: When waste residue and waste steel slag are fed into the magnetic separator 1 through the feed inlet 101, the external controller activates the drive motor 102. With the assistance of the auxiliary shaft 104, guide rail seat 103, and guide rail ring 109, the rotating drive motor 102 can smoothly drive the left limiting disk 110 and the right limiting disk 113 to rotate. The synchronously rotating left limiting disk 110 and right limiting disk 113 can drive the energized electromagnetic rod 112 to rotate. With the cooperation of the barrier sleeve 111 set outside the electromagnetic rod 112, the waste residue and waste steel slag fed into the feed inlet 101 can be dispersed. This avoids the accumulation of waste steel slag. When energized, the electromagnetic rod 112 can adsorb the dispersed waste steel slag onto the outside of the barrier sleeve 111. At the same time, the electromagnetic rod 112 and the barrier sleeve 111, which rotate with the left limiting disk 110 and the right limiting disk 113, can further disperse the waste slag and waste steel slag that fall into the lower part of the magnetic separator 1, and further adsorb the waste steel slag. After the waste steel slag is adsorbed, it is discharged through the discharge chute 108. The external controller cuts off the power to the electromagnetic rod 112, so that the waste steel slag adsorbed on the outside of the barrier sleeve 111 can be discharged through the discharge chute 108 after the waste slag is discharged, which is convenient for people to use.

[0034] It should be noted that the electromagnetic rod 112 and drive motor 102 used in this magnetic separator can be purchased directly from the market. In order to facilitate the connection and disconnection of the electromagnetic rod 112, the drive motor 102 drives the left limiting disk 110 and the right limiting disk 113 to rotate between +720 degrees and -720 degrees. The time for the left limiting disk 110 and the right limiting disk 113 to complete one revolution is between 15 seconds and one minute. At the same time, the connection method and electrical connection relationship of each component adopt mature conventional methods in the existing technology, so they will not be described in detail here.

[0035] Example 2

[0036] Based on Embodiment 1, this utility model is as follows: Figures 1-5As shown, an auxiliary shaft 104 is movably connected to the right side of the magnetic separator 1 via a bearing, and the left side of the auxiliary shaft 104 is fixedly connected to the right side of the right limiting disk 113. A first sprocket 105 is fixedly installed on the right side of the auxiliary shaft 104. A support base 2 is fixedly installed at the bottom of the magnetic separator 1. A rotating shaft 201 is movably connected to the upper end of the inner cavity of the support base 2 via a bearing. A second sprocket 107 is fixedly installed on the right side of the rotating shaft 201, and the outer diameter of the second sprocket 107 is larger than that of the first sprocket 105. The diameter is as follows: a chain 106 is sleeved on the outer side of the first sprocket 105 and the second sprocket 107; an arc-shaped guide groove 404 is opened at the lower end of the discharge trough 108; an arc-shaped sealing plate 4 is slidably connected to the inner side of the arc-shaped guide groove 404; an arc-shaped seat 402 is fixedly connected to the left and right ends of the bottom of the arc-shaped sealing plate 4; an arc-shaped toothed plate 403 is fixedly installed on the top and bottom of the inner side of the arc-shaped seat 402; and half gears 202 that mesh with the arc-shaped toothed plate 403 are fixedly installed on the left and right ends of the outer surface of the rotating shaft 201.

[0037] This technical solution: Through the cooperation of the first sprocket 105, chain 106, and second sprocket 107, after the auxiliary shaft 104 rotates two revolutions clockwise, the rotating shaft 201 can drive the half gear 202 to rotate half a revolution. With the assistance of the meshing arc-shaped toothed plate 403, the arc-shaped sealing plate 4 can slide backward within the arc-shaped guide groove 404 via the arc-shaped seat 402. This causes the arc-shaped sealing plate 4 and the discharge chute 108 to change from a sealed state to an open state, allowing the waste residue to be discharged downward through the discharge chute 108. Then, the auxiliary... After the shaft 104 rotates four times in the reverse direction, the rotating shaft 201 can drive the half gear 202 to rotate one revolution. With the assistance of the meshing arc-shaped toothed plate 403, the arc-shaped sealing plate 4 can slide from the rear end to the front end in the arc-shaped guide groove 404 via the arc-shaped seat 402. This causes the arc-shaped sealing plate 4 and the discharge trough 108 to change from an open state to a sealed state, and then back to an open state. At this time, the waste steel slag can be discharged downward through the discharge trough 108, which is convenient for the staff to use. Then, the auxiliary shaft 104 rotates two revolutions in the forward direction and then resets.

[0038] It should be noted that the fit between the first sprocket 105 and the second sprocket 107 used in this device can be set according to the specific application.

[0039] Example 3

[0040] Based on Embodiment 1, this utility model is as follows: Figures 1-5 As shown, a collection box 3 is provided at the bottom of the inner side of the support base 2. Handles 301 are fixedly installed on both the front and rear sides of the collection box 3. A triangular partition block 302 is fixedly installed at the bottom of the inner cavity of the collection box 3. An n-shaped shielding seat 401 is fixedly installed at the middle of the bottom of the arc-shaped sealing plate 4.

[0041] This technical solution: With the addition of the collection box 3, waste residue and waste steel slag can be collected separately with the assistance of the triangular partition block 302. When the arc-shaped sealing plate 4 slides backward in the arc-shaped guide groove 404, and with the cooperation of the n-shaped shielding seat 401, which moves with the arc-shaped sealing plate 4, at the upper end of the triangular partition block 302, the waste residue can fall fully into the collection box 3. As the arc-shaped seat 402 drives the arc-shaped sealing plate 4 to slide from the rear end to the front end in the arc-shaped guide groove 404, the arc-shaped sealing plate 4 and the discharge chute 108 change from an open state to a sealed state, and then back to an open state. With the cooperation of the n-shaped shielding seat 401, which moves with the arc-shaped sealing plate 4, at the upper end of the triangular partition block 302, the waste steel slag can fall fully into the collection box 3 for collection, which is convenient for people to use.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
