Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel slag recycling devices, specifically a steel slag recycling device. Background Technology
[0002] Steel slag mainly comes from blast furnace slag produced by blast furnace ironmaking, converter slag produced by converter steelmaking, and electric arc furnace steelmaking slag. Recycling requires timely collection of the waste slag after it is discharged from the production equipment to avoid mixing with other industrial wastes, thus ensuring the purity and recycling value of the waste slag. Converter slag is discharged in a solid state and needs pretreatment such as crushing and screening to remove metallic iron and other impurities, which necessitates the use of steel slag recycling equipment.
[0003] Traditional steel slag recycling equipment requires the steel slag to be crushed first. However, traditional equipment can only crush the slag once, which may result in insufficient crushing of all the steel slag. This prevents the incomplete crushing of the slag and thus affects the recycling efficiency, ultimately leading to the inability to fully recycle the steel slag. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a steel slag recycling device that features secondary crushing and ease of use, thus solving the problems mentioned in the background section.
[0005] This utility model provides the following technical solution: a steel slag recycling device, including a crushing chamber, a first crushing roller rotatably connected to the inner cavity of the crushing chamber, a second crushing roller rotatably connected to the inner cavity of the crushing chamber, a crushing motor fixedly mounted on the outer wall of the crushing chamber, a screen plate fixedly mounted on the inner cavity of the crushing chamber, a connecting cylinder installed on the outer wall of the crushing chamber, a lifting cylinder fixedly mounted on the outer wall of the connecting cylinder, a spiral lifting rod rotatably connected to the inner cavity of the lifting cylinder, a feeding trough fixedly mounted on the outer wall of the lifting cylinder, a lifting motor fixedly mounted on the top of the lifting cylinder, a collection chamber fixedly mounted on the bottom of the crushing chamber, a limiting plate fixedly mounted on the inner wall of the collection chamber, a limiting groove formed on the inner wall of the limiting plate, an electromagnet plate slidably connected to the inner wall of the limiting groove, a hydraulic cylinder fixedly mounted on the outer wall of the limiting plate, a bearing plate fixedly mounted on the inner wall of the collection chamber, a rotating shaft rotatably connected to the inner cavity of the collection chamber, a protrusion fixedly mounted on the outer wall of the rotating shaft, a collection box installed on the outer side of the collection chamber, and a drive motor fixedly mounted on the outer wall of the collection chamber.
[0006] As a preferred technical solution of this utility model: the inner cavity of the connecting cylinder is connected to the inner cavity of the lifting cylinder, and the power output shaft of the lifting motor is fixedly equipped with a spiral lifting rod.
[0007] As a preferred technical solution of this utility model: the installation position of the feeding trough corresponds to the top of the crushing chamber, and the inclination angle between the outer wall of the screen plate and the inner wall of the crushing chamber is 15 degrees.
[0008] As a preferred technical solution of this utility model: the inner cavity of the crushing chamber is connected to the inner cavity of the collecting chamber, and the output shaft of the hydraulic cylinder is connected to the outer wall of the electromagnet plate.
[0009] As a preferred technical solution of this utility model: there are two limiting plates, and the two limiting plates are respectively installed on the inner walls of the two sides of the collection chamber.
[0010] As a preferred technical solution of this utility model: the outer wall of the protrusion is in contact with the bottom of the bearing plate, and the power output shaft of the drive motor is connected to the outer wall of the rotating shaft.
[0011] As a preferred technical solution of this utility model: the drive motor is a high-speed low-torque motor, and the support plate is made of stainless steel.
[0012] As a preferred technical solution of this utility model: the thickness of the outer wall of the electromagnet plate matches the height between the inner wall of the limiting groove, and the sieve plate is made of high carbon steel.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This steel slag recycling device uses an elevator cylinder installed outside the crushing chamber. Under the action of the screen plate, the incompletely crushed steel slag is filtered, allowing the steel slag to enter the elevator cylinder through the connecting cylinder. Under the action of the spiral lifting rod, the steel slag is lifted upward and then released into the crushing chamber through the discharge chute for further crushing. This avoids the traditional equipment that only performs one crushing. Under the action of secondary crushing, the steel slag can achieve a better crushing effect, thereby better recovering the metal in the steel slag.
[0015] 2. This steel slag recycling device uses a support plate installed in the collection bin and a drive shaft installed at the bottom of the support plate. Under the action of the drive motor, the drive shaft rotates, causing the protrusions to push the bottom of the support plate. This causes the steel slag to vibrate on the top of the support plate. In the process of steel slag vibration, the metal in the steel slag is adsorbed, avoiding the accumulation of steel slag, which would prevent the metal from being completely adsorbed, thus improving the recycling effect.

[0022] 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.
[0023] Please see Figure 1 - Figure 5 A steel slag recycling device includes a crushing chamber 1. A first crushing roller 2 is rotatably connected to the inner cavity of the crushing chamber 1. A second crushing roller 3 is rotatably connected to the inner cavity of the crushing chamber 1. A crushing motor 4 is fixedly mounted on the outer wall of the crushing chamber 1. A screen plate 5 is fixedly mounted on the inner cavity of the crushing chamber 1. A connecting cylinder 7 is installed on the outer wall of the crushing chamber 1. A lifting cylinder 6 is fixedly mounted on the outer wall of the connecting cylinder 7. A spiral lifting rod 20 is rotatably connected to the inner cavity of the lifting cylinder 6. A discharge chute 9 is fixedly mounted on the outer wall of the lifting cylinder 6. A lifting motor 8 is fixedly mounted on the top of the lifting cylinder 6. A collection chamber 10 is fixedly mounted at the bottom. A limit plate 11 is fixedly mounted on the inner wall of the collection chamber 10. A limit groove 12 is formed on the inner wall of the limit plate 11. An electromagnet plate 13 is slidably connected to the inner wall of the limit groove 12. A hydraulic cylinder 14 is fixedly mounted on the outer wall of the limit plate 11. A bearing plate 15 is fixedly mounted on the inner wall of the collection chamber 10. A rotating shaft 16 is rotatably connected to the inner cavity of the collection chamber 10. A protrusion 17 is fixedly mounted on the outer wall of the rotating shaft 16. A collection box 19 is installed on the outer side of the collection chamber 10. A drive motor 18 is fixedly mounted on the outer wall of the collection chamber 10.
[0024] In the above structure, by setting the first crushing roller 2 and the second crushing roller 3 in the inner cavity of the crushing chamber 1, the steel slag added to the inner cavity of the crushing chamber 1 can be crushed during the rotation of the first crushing roller 2 and the second crushing roller 3. The steel slag is crushed and falls onto the top of the screen plate 5 after crushing, so as to screen the crushed steel slag and thus better recover the metal mixed in the steel slag.
[0025] In a preferred embodiment: the inner cavity of the connecting cylinder 7 is connected to the inner cavity of the lifting cylinder 6, and the power output shaft of the lifting motor 8 is fixedly equipped with a spiral lifting rod 20.
[0026] In the above structure, the spiral lifting rod 20 installed in the inner cavity of the lifting cylinder 6 and the lifting motor 8 installed on the top of the lifting cylinder 6 can drive the spiral lifting rod 20 under the action of the lifting motor 8, so that the spiral lifting rod 20 rotates in the inner cavity of the lifting cylinder 6. As the spiral lifting rod 20 rotates, the material filtered by the screen plate 5 can be lifted upward for secondary crushing.
[0027] In a preferred embodiment, the installation position of the feeding trough 9 corresponds to the top of the crushing chamber 1, and the inclination angle between the outer wall of the screen plate 5 and the inner wall of the crushing chamber 1 is 15 degrees.
[0028] In the above structure, the incompletely crushed steel slag is lifted upward by the lifting motor 8 and the spiral lifting rod 20 through the feeding trough 9 on the outer wall of the lifting cylinder 6, and then released into the inner cavity of the crushing chamber 1 through the feeding trough 9. Thereby, the slag is crushed again by the action of the first crushing roller 2 and the second crushing roller 3 in the inner cavity of the crushing chamber 1, so as to better recover the metal in the steel slag.
[0029] In a preferred embodiment: the inner cavity of the crushing chamber 1 is connected to the inner cavity of the collecting chamber 10, and the output shaft of the hydraulic cylinder 14 is connected to the outer wall of the electromagnet plate 13.
[0030] In the above structure, the hydraulic cylinder 14 installed on the outer wall of the limiting plate 11 drives the electromagnet plate 13, causing it to move along the inner wall of the limiting groove 12 and move it outward from the inner cavity of the collection chamber 10. This allows the steel slag filtered by the screen plate 5 to fall onto the top of the bearing plate 15.
[0031] In a preferred embodiment, there are two limiting plates 11, and the two limiting plates 11 are respectively installed on the inner walls of the two sides of the collection chamber 10.
[0032] In the above structure, the limiting plates 11 provided on the inner walls on both sides of the collection bin 10 can restrict the electromagnet plate 13 under the action of the limiting plates 11, so that the electromagnet plate 13 can be driven by the hydraulic cylinder 14, so that the electromagnet plate 13 can move outward from the inner cavity of the collection bin 10 or stay in the inner cavity of the collection bin 10, so as to adsorb the metal in the steel slag under the action of the electromagnet plate 13.
[0033] In a preferred embodiment: the outer wall of the protrusion 17 contacts the bottom of the support plate 15, and the power output shaft of the drive motor 18 is connected to the outer wall of the rotating shaft 16.
[0034] In the above structure, the rotating shaft 16 is installed in the inner cavity of the collection chamber 10, and the protrusion 17 is installed on the power output shaft of the rotating shaft 16. Under the action of the drive motor 18, the rotating shaft 16 is driven to rotate, thereby driving the protrusion 17. At this time, under the action of the rotating shaft 16 and the protrusion 17, the bearing plate 15 can be continuously vibrated, causing the steel slag to vibrate and roll on the top of the bearing plate 15, so that it can be better adsorbed under the action of the electromagnet plate 13.
[0035] In a preferred embodiment: the drive motor 18 is a high-speed, low-torque motor, and the support plate 15 is made of stainless steel.
[0036] In the above structure, the steel slag after being crushed and filtered is placed on the support plate 15 in the inner cavity of the collection chamber 10. By adjusting the position of the electromagnet plate 13, the electromagnet plate 13 is moved to the outside of the collection chamber 10. At this time, the crushed steel slag will fall to the top of the support plate 15. Then, under the action of the drive motor 18 and the rotating shaft 16, the steel slag can be vibrated on the top of the support plate 15. During the vibration, the metal is better adsorbed under the action of the electromagnet plate 13.
[0037] In a preferred embodiment, the thickness of the outer wall of the electromagnet plate 13 matches the height between the inner wall of the limiting groove 12, and the sieve plate 5 is made of high carbon steel.
[0038] In the above structure, the position of the electromagnet plate 13, which is set in the inner cavity of the limiting groove 12, can be adjusted under the action of the hydraulic cylinder 14, so that the electromagnet plate 13 can be in the inner cavity of the collection chamber 10 and can also move outward, so that the crushed and screened steel slag can fall smoothly onto the top of the bearing plate 15.
[0039] Working Principle: During operation, when steel slag needs to be crushed, the steel slag is fed into the inner cavity of the crushing chamber 1. Then, under the action of the first crushing roller 2 and the second crushing roller 3, the steel slag is crushed, causing it to fall onto the top of the screen plate 5. The screen plate 5 filters the steel slag; smaller particles pass through the screen plate 5 and fall to the top of the bearing plate 15, while larger particles cannot pass through the screen plate 5 and instead enter the inner cavity of the lifting cylinder 6 via the connecting cylinder 7. At this point, the lifting motor 8 drives the rotation of the spiral lifting rod 20, lifting the larger particles upwards into the inner cavity of the discharge trough 9, and then releasing them into the inner cavity of the crushing chamber 1 for secondary crushing. To adsorb the steel slag that has fallen onto the top of the support plate 15, the electromagnet plate 13 is moved from the outside of the collection chamber 10 to the inside of the collection chamber 10 by the hydraulic cylinder 14, and the drive motor 18 is started. The drive motor 18 drives the rotating shaft 16 to rotate, causing the protrusion 17 to vibrate the bottom of the support plate 15. Under the action of the vibration of the support plate 15, the steel slag can vibrate continuously, so that the electromagnet plate 13 can better adsorb the metal in the steel slag. After adsorption, the electromagnet plate 13 is pushed out of the inside of the collection chamber 10 by the hydraulic cylinder 14, so that the electromagnet plate 13 moves to the top of the collection box 19. Then, under the action of the electromagnet plate 13, the metal is released into the inside of the collection box 19 for collection.
