Description

Technical Field

[0001] This invention relates to the field of metal recycling technology, specifically to a waste steel slag recycling and reuse equipment. Background Technology

[0002] Steel slag is a waste residue produced in the metallurgical industry and a byproduct of the steelmaking process. It contains various useful components: 2%–8% metallic iron, 40%–60% calcium oxide, 3%–10% magnesium oxide, and 1%–8% manganese oxide. Therefore, it can be used as a raw material in iron and steel metallurgy. Currently, steel slag produced by steel enterprises cannot be disposed of in a timely manner, resulting in large amounts of steel slag occupying land and polluting the environment. However, steel slag is not an unusable solid waste; it contains a large amount of slag steel, calcium oxide, iron, and magnesium oxide, among other usable components. Therefore, in order to enable steel enterprises to create economic and environmental benefits...

[0003] In the process of steel slag recycling, steel slag contains both metal and impurities. During metal recycling, the impurities on the outside of the metal make it difficult to separate from the metal. Directly calcining the steel slag to purify the metal increases energy consumption, resulting in a large amount of energy being needed for steel slag recycling and reuse. Furthermore, the melting process requires a long heating time, which is time-consuming. Therefore, we propose a waste steel slag recycling and reuse equipment. Summary of the Invention

[0004] To address the shortcomings of existing waste steel slag recycling and reuse equipment, this invention provides a waste steel slag recycling and reuse equipment that features the advantages of crushing steel slag through a grinding box, separating impurities from molten metal, and absorbing metal from the waste slag using magnetic adsorption, thereby improving metal purification efficiency and solving the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a waste steel slag recycling and reuse treatment device, including a base, a first baffle and a second baffle mounted on the upper part of the base via a bracket, a limiting post fixed between the first baffle and the second baffle, a roller sleeved to the outside of the limiting post, an installation sleeve fixedly connected to the outside of the first baffle, an outer sleeve sleeved to the outside of the installation sleeve, the roller penetrating the interior of the first baffle, and a first gear clamped to the end of the roller, a second limiting plate limiting the position of the outer sleeve mounted on the outside of the second baffle, an impurity outlet for discharging impurities mounted at the lower end of the second baffle, a steel collection pipe fixedly connected inside the first baffle and the second baffle, a first bracket mounted on one side of the upper part of the base, a grinding box fixedly connected to the end of the first bracket, a filter screen fixedly connected to the bottom of the grinding box, a rotating cover plate mounted on the upper end of the grinding box, a grinding roller eccentrically mounted inside the rotating cover plate, and steel slag inlets for conveying slag mounted on both sides of the outside of the grinding box.

[0006] Preferably, a permanent magnet is installed inside the limiting post, the permanent magnet is located on one side inside the base, and the steel collecting pipe is arranged on the side of the permanent magnet.

[0007] Preferably, a spiral conveying pipe is installed inside the steel collecting pipe, a metal discharge port is fixedly connected to the end of the steel collecting pipe, and an opening is provided at the upper end of the steel collecting pipe.

[0008] Preferably, a first limiting plate is installed on the outside of the first baffle to limit the roller and the first gear, and a first motor is installed on the outside of the first baffle. The gear installed at one end of the output shaft of the first motor meshes with the inner side of the first limiting plate.

[0009] Preferably, a second gear is fixed to one end of the outer sleeve, a second motor is installed on the outside of the second baffle, and a gear installed on one end of the output shaft of the second motor meshes with the outside of the second gear.

[0010] Preferably, the outer sleeve is fitted onto the outside of the drum, while the steel collecting pipe is installed between the drum and the outer sleeve.

[0011] Preferably, a material conveying pipe is fixedly connected to the lower end of the grinding box, and the material conveying pipe extends into the interior of the mounting sleeve.

[0012] Preferably, an auxiliary gear is fixedly connected to the top of the grinding roller, the grinding roller is attached to the inner side of the grinding box, and the filter screen has filter holes inside, and the auxiliary gear meshes with the inner side of the grinding box.

[0013] Preferably, a third motor is installed on one side of the grinding box, and one end of the output shaft of the third motor meshes with the outside of the rotating cover plate.

[0014] Compared with existing waste steel slag recycling and reuse equipment, the present invention has the following advantages:

[0015] 1. This waste steel slag recycling and reuse equipment grinds the steel slag by placing it inside a grinding box and rotating the grinding rollers eccentrically through a rotating cover plate. The ground steel slag then slides down through a filter screen, thus breaking it down into granules and separating the metallic iron and impurities from the steel slag. This prevents impurities from adhering to the metallic iron, which would otherwise waste energy during subsequent metal refining, thereby improving the efficiency of metal separation.

[0016] 2. This waste steel slag recycling and reuse equipment transports the pre-ground steel slag into the interior of the mounting sleeve. At the same time, the second motor drives the outer sleeve to rotate, ensuring sufficient downward sliding of the metal. Meanwhile, the permanent magnet drives the metal to be adsorbed on the outside of the drum, improving the separation efficiency between the metal and impurities. After the adsorbed metal is transported to the other side, the permanent magnet stops adsorbing the metal, and the metal slides into the interior of the steel collection pipe, ensuring the efficiency and completeness of metal separation.

[0017] 3. This waste steel slag recycling and reuse equipment effectively grinds the waste steel slag through a grinding box, which effectively separates the metallic iron from impurities in the steel slag. At the same time, the ground steel slag is transported to the inside of the outer sleeve, where a permanent magnet adsorbs the metal in the ground steel slag, thus effectively separating the metal from impurities in the steel slag. After the metal is calcined, the impurities in the metal can be reduced, and the metal recovery efficiency can be improved. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A waste steel slag recycling and reuse equipment includes a base 1. A first baffle 2 and a second baffle 3 are mounted on the upper part of the base 1 via a bracket. The first baffle 2 and the second baffle 3 form a roller to process the steel slag. A limiting post 4 is fixed between the first baffle 2 and the second baffle 3. A roller 6 is sleeved on the outside of the limiting post 4. The roller 6 is sleeved on the outside of the limiting post 4 and a permanent magnet 5. The permanent magnet 5 drives the metal to be adsorbed on the outside of the roller 6. When the roller 6 rotates, it moves the adsorbed metal. An installation sleeve 7 is fixedly connected to the outside of the first baffle 2. An outer sleeve 8 is sleeved on the outside of the installation sleeve 7. When the outer sleeve 8 rotates, it drives the steel slag to slide downwards, and the rotation of the outer sleeve 8 separates the steel slag, improving the adsorption effect of the permanent magnet 5 on the metallic iron in the steel slag. The roller 6 penetrates the interior of the first baffle 2, and a first gear 9 is snapped onto the end of the roller 6. A second limiting plate 14 is installed on the outside of the second baffle 3 to limit the position of the outer sleeve 8. The second limiting plate 14 is installed outside the second baffle 3. The second limiting plate 14 limits the position of the outer sleeve 8 outside the second baffle 3. The lower end of the second baffle 3 is equipped with an impurity outlet 15 for driving impurities out. The first baffle 2 and the second baffle 3 are fixedly connected to a steel collection pipe 16. After the metal iron is adsorbed by the roller 6, the adsorbed metal is transported to the inside of the steel collection pipe 16 for discharge. The upper side of the base 1 is equipped with a first bracket 19. The end of the first bracket 19 is fixedly connected to a grinding box 20. The grinding box 20 grinds the metal and drives the steel slag to grind into particles. At the same time, it separates the metal and impurities. The bottom of the grinding box 20 is fixedly connected to a filter screen 22. The upper end of the grinding box 20 is equipped with a rotating cover plate 23. The grinding roller 24 is installed eccentrically inside the rotating cover plate 23. The rotating cover plate 23 drives the grinding roller 24 to rotate. During the rotation of the grinding roller 24, the metal is ground. The two sides of the outside of the grinding box 20 are equipped with steel slag inlets 26 for driving the slag to be transported.

[0027] Please see Figure 5 A permanent magnet 5 is installed inside the limiting post 4. The permanent magnet 5 is located on one side inside the base 1, and the steel collection pipe 16 is set on the side of the permanent magnet 5. Through the permanent magnet 5 installed inside the limiting post 4 and the steel collection pipe 16 set on one side of the permanent magnet 5, the permanent magnet 5 adsorbs the steel passing through the steel slag. When the roller 6 moves the adsorbed steel slag to one side of the steel collection pipe 16, the permanent magnet 5 stops adsorbing the steel slag, and the steel slag falls into the impurity discharge port 15. That is, the impurity discharge port 15 can collect and process the steel slag.

[0028] Please see Figure 3 and Figure 5The steel collection pipe 16 has a spiral conveying pipe 17 installed inside. A metal outlet 18 is fixedly connected to the end of the steel collection pipe 16. The upper end of the steel collection pipe 16 has an opening. Through the metal outlet 18 installed at the end of the steel collection pipe 16, the roller 6 rotates and drives the adsorbed steel to be conveyed to the impurity outlet 15. Then, the steel collection pipe 16 is started. When the steel collection pipe 16 rotates, it drives the steel to be conveyed to one side, that is, discharged through the metal outlet 18, thereby improving the steel discharge efficiency.

[0029] Please see Figure 2 A first limiting plate 10 is installed on the outside of the first baffle 2 to limit the roller 6 and the first gear 9. A first motor 11 is installed on the outside of the first baffle 2. The gear installed at one end of the output shaft of the first motor 11 meshes with the inner side of the first limiting plate 10. The first limiting plate 10 is installed by snapping on the outside of the roller 6 to improve the stability of the first gear 9 when the position of the roller 6 is limited. At the same time, the first motor 11 is installed on the outside of the first baffle 2. When the first motor 11 is started, the first motor 11 drives the gear to mesh with the inner side of the first gear 9, that is, the first motor 11 provides power for the rotation of the first gear 9.

[0030] Please see Figure 3 A second gear 12 is fixed to one end of the outer sleeve 8. A second motor 13 is installed on the outside of the second baffle 3. The gear installed on one end of the output shaft of the second motor 13 meshes with the outside of the second gear 12. By starting the second motor 13, the second motor 13 drives the gear to mesh with the second gear 12, that is, the second motor 13 drives the second gear 12 to rotate, and the second gear 12 drives the outer sleeve 8 to rotate, that is, it drives the steel slag to rotate inside the outer sleeve 8, thereby improving the adsorption efficiency. At the same time, it can drive the waste slag to be discharged through the impurity discharge port 15.

[0031] Please see Figure 5 The outer sleeve 8 is fitted onto the outside of the drum 6, and the steel collection pipe 16 is installed between the drum 6 and the outer sleeve 8. After the steel slag is transported to the inside of the mounting sleeve 7 via the conveying pipe 21, the mounting sleeve 7 and the outer sleeve 8 are in an inclined state, that is, the steel slag slides down. At the same time, the permanent magnet 5 adsorbs the steel slag. When the outer sleeve 8 rotates, it improves the mixing of the steel slag and makes it easier to control the adsorption efficiency of the permanent magnet 5 on the steel. At the same time, the rotation of the outer sleeve 8 provides power for the discharge of waste through the impurity discharge port 15.

[0032] Please see Figure 1The lower end of the grinding box 20 is fixedly connected to a conveying pipe 21, which extends into the interior of the mounting sleeve 7. After the grinding box 20 grinds and crushes the steel, it can separate the steel from the steel slag. The separated steel slag is then transported to the interior of the mounting sleeve 7 via the conveying pipe 21. At the same time, the permanent magnet 5 installed inside the mounting sleeve 7 attracts the steel, and the slag is discharged as the outer sleeve 8 moves.

[0033] Please see Figure 6 An auxiliary gear 25 is fixedly connected to the top of the grinding roller 24. The grinding roller 24 is fitted against the inner side of the grinding box 20, and filter holes are opened inside the filter screen 22. The auxiliary gear 25 meshes with the inner side of the grinding box 20. The grinding roller 24 is installed at an eccentric position at the lower end of the rotating cover plate 23. When the rotating cover plate 23 drives the grinding roller 24 to rotate, the rotating cover plate 23 drives the grinding roller 24 to rotate inside the grinding box 20. After the steel slag inlet 26 carries the steel slag into the interior of the grinding box 20, The grinding roller 24 grinds the steel slag filled inside the grinding box 20, turning the steel slag into granules. At the same time, it effectively separates impurities such as metallic iron and calcium oxide from the steel slag. When the grinding roller 24 rotates, it drives the auxiliary gear 25 to mesh with the inner side of the grinding box 20. That is, when the grinding roller 24 rotates eccentrically, it can rotate on its own axis, ensuring that the grinding roller 24 grinds the steel slag thoroughly. Meanwhile, the filter screen 22 has holes inside, which filter out the granular impurities formed after grinding.

[0034] Please see Figure 6 A third motor 27 is installed on one side of the grinding box 20. One end of the output shaft of the third motor 27 meshes with the outside of the rotating cover plate 23. By starting the third motor 27 installed on one side of the grinding box 20, the third motor 27 drives the rotating cover plate 23 to rotate, thus providing power for the grinding roller 24 to rotate inside the grinding box 20.

[0035] Working principle: During use, steel slag is conveyed into the grinding box 20 through the steel slag inlet 26. Simultaneously, the third motor 27 is started, driving the rotating cover plate 23 to rotate. The rotating cover plate 23 drives the grinding roller 24 to rotate eccentrically, grinding the steel slag inside the grinding box 20 and separating impurities such as metallic iron and calcium oxide. When the grinding roller 24 rotates eccentrically, it meshes with the inner side of the grinding box 20 via the auxiliary gear 25, allowing the grinding roller 24 to rotate and improve the grinding efficiency of the steel slag. The ground steel slag slides down through the grinding box 20, while the conveying pipe 21 transports the steel slag to the inside of the mounting sleeve 7. The second motor 13 and the first motor 11 are then started. Motor 13 drives the outer sleeve 8 to rotate. During the rotation of the outer sleeve 8, the steel slag rolls and moves downward inside the outer sleeve 8. Meanwhile, the permanent magnet 5 attracts the metallic iron in the steel slag. The metallic iron is attracted to the outside of the drum 6. At the same time, the first motor 11 drives the drum 6 to rotate. The drum 6 moves the attracted metallic iron upward. After the drum 6 moves the metallic iron away from the outside of the permanent magnet 5, the metallic iron slides into the inside of the steel collection pipe 16. The spiral conveyor pipe 17 is activated. The spiral conveyor pipe 17 carries the metallic iron out through the metal discharge port 18. At the same time, impurities are discharged through the impurity discharge port 15. This ensures that the metal and impurities in the steel slag are separated, avoiding excessive waste in the steel slag and affecting the subsequent metal recovery efficiency.
