Description

Technical Field

[0001] This utility model relates to the technical field of deoxidizer processing equipment, and in particular to a pelletizing device for aluminum slag removal and deoxidizer. Background Technology

[0002] In the steelmaking process of the metallurgical industry, aluminum slag remover and deoxidizer plays a key role in improving the quality of molten steel. It can react with dissolved oxygen in molten iron to produce non-metallic compounds, which then precipitate and float to the slag layer, thereby purifying the molten iron. As the industry's requirements for steel quality continue to rise, the demand for efficient preparation of aluminum slag remover and deoxidizer is becoming increasingly urgent, and aluminum slag remover and deoxidizer pelletizing devices have emerged to meet this need.

[0003] The prior art discloses a hot pressing device for aluminum-manganese alloy deoxidizer with application number CN202020435291.8, which relates to the field of deoxidizer briquetting technology. This utility model has multiple electric heating tubes installed in the briquetting chamber above two briquetting rollers. After aluminum powder enters, the multiple electric heating tubes penetrate the interior of the aluminum powder, which can heat the aluminum powder relatively quickly and evenly, so that the aluminum powder is hot-pressed into briquettes in a high-temperature chamber, which improves the quality of aluminum briquette deoxidizer. It is practical and suitable for widespread promotion and use.

[0004] In the pelletizing process described above, some raw materials enter the pellet trough and some raw materials are located between the connected pellet troughs. As the extrusion proceeds, the raw materials are extruded into spherical and sheet shapes. Adjacent spherical deoxidizers and sheet deoxidizers are connected together, which requires subsequent separation and increases the cost of secondary processing. Utility Model Content

[0005] To solve the above problems, this utility model provides a pelletizing device for aluminum slag removal and deoxidation agents.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an aluminum slag removal and deoxidizing agent pelletizing device, comprising a device body, a first driving mechanism provided on the side surface of the device body, a pelletizing roller connected to the output end of the first driving mechanism via a rotating shaft, and a first gear mounted on the surface of the rotating shaft, with two first gears meshing together; a V-shaped plate welded to the upper surface of the inner bottom surface of the device body via a vibration isolation spring support leg, and a vibration motor mounted on the lower surface of the V-shaped plate via anti-loosening bolts; and filter holes opened on the surface of the V-shaped plate.

[0007] By adopting the above technical solution, through the innovative combination of V-shaped plate and vibrating motor, the inertial force and collision effect generated by high-frequency vibration can be used to quickly break the adhesive structure of spherical and sheet-like deoxidizers, avoiding the secondary separation process caused by the connection of adjacent spherical and sheet-like deoxidizers in traditional technology, significantly reducing the energy consumption and labor costs generated by secondary processing. At the same time, the filter hole design on the surface of the V-shaped plate, combined with the inclined plate surface, can effectively remove unqualified spherical deoxidizers and impurities.

[0008] Furthermore, a demolding rod is installed inside the device body and below the ball forming roller. A rubber demolding pad is installed on the surface of the demolding rod, and a second gear is installed on the surface of the demolding rod, and the second gear is meshed with the first gear.

[0009] By adopting the above technical solution, a demolding rod is set below the ball forming roller. The rubber demolding pad on its surface can flexibly contact the ball forming roller to avoid damage to the roller surface by hard friction. At the same time, the gear meshing is used to realize the synchronous linkage between the demolding action and the rotation of the ball forming roller, ensuring that the raw material quickly leaves the roller body after balling, preventing adhesion and accumulation, and improving production efficiency.

[0010] Furthermore, a second drive mechanism is bolted to the side surface of the device body, and a crushing roller is mounted on the output end of the second drive mechanism via a rotating shaft. The surface of the crushing roller is provided with protruding ridges, and a third gear is mounted on the surface of the rotating shaft. The two third gears are meshed together.

[0011] By adopting the above technical solution, the second drive mechanism drives the crushing roller to rotate, and large pieces of raw materials are crushed. This avoids large pieces of material from directly entering the rollers and causing impact, thereby reducing the extrusion load on the ball forming roller.

[0012] Furthermore, both the first and second drive mechanisms are composed of a drive motor and a reducer, with the output end of the drive motor connected to the reducer.

[0013] By adopting the above technical solutions, the rotation speed and torque can be precisely adjusted according to the requirements of different processes such as pelletizing and crushing, which can ensure pelletizing pressure and control crushing force, thereby improving the adaptability of the equipment.

[0014] Furthermore, a feeding bin is welded to the upper surface of the device body, and the feeding bin has a cone-shaped funnel structure.

[0015] By adopting the above technical solution, the cone-shaped funnel-shaped feed hopper can use gravity to accelerate the falling of raw materials, avoid blockage, and improve feeding efficiency.

[0016] Furthermore, a polyurethane buffer pad is adhered to the upper surface of the V-shaped plate, and the upper surface of the polyurethane buffer pad is provided with through holes for use with the filter holes.

[0017] By adopting the above technical solution, not only is vibration and noise reduced, but polyurethane also possesses a unique elastomer structure with a moderate elastic modulus, enabling it to undergo significant elastic deformation upon impact. When the spherical deoxidizer falls onto the V-shaped plate, the polyurethane buffer pad absorbs the impact energy through its own deformation, converting mechanical energy into internal energy, thereby reducing the impact force generated by the collision between the deoxidizer and the plate surface. Compared to rigid materials, the polyurethane buffer pad can reduce the peak impact force by more than 60%, effectively preventing the deoxidizer from breaking due to excessive instantaneous impact.

[0018] Furthermore, the lower surface of the device body is welded with a support leg, and the lower surface of the support leg is provided with a shock-absorbing and anti-slip pad.

[0019] By adopting the above technical solution, the shock-absorbing and anti-slip pads under the support feet can reduce the transmission of vibration during the operation of the device, prevent the equipment from shifting, and improve the stability of operation.

[0020] Furthermore, an integrated controller is bolted to the side surface of the device body, and a protective pad is adhered to the back of the integrated controller.

[0021] By adopting the above technical solution, the ball forming roller, crushing roller and vibrating motor are linked by an integrated controller, and the rotation speed, vibration frequency and other parameters are automatically adjusted according to the real-time status of the raw materials, thereby improving the separation adaptability.

[0022] In summary, this utility model has the following beneficial effects: 1. In this application, the innovative combination of V-shaped plate and vibrating motor utilizes the inertial force and collision effect generated by high-frequency vibration to quickly break the adhesive structure of spherical and sheet-like deoxidizers, avoiding the secondary separation process caused by the connection of adjacent spherical and sheet-like deoxidizers in traditional technology, significantly reducing the energy consumption and labor costs generated by secondary processing. At the same time, the filter hole design on the surface of the V-shaped plate, combined with the inclined plate surface, can effectively remove unqualified spherical deoxidizers and impurities. 2. In this application, a demolding rod is provided below the ball forming roller. The rubber demolding pad on its surface can flexibly contact the ball forming roller to avoid damage to the roller surface by hard friction. At the same time, the gear meshing is used to realize the synchronous linkage between the demolding action and the rotation of the ball forming roller, ensuring that the raw material quickly leaves the roller body after balling, preventing adhesion and accumulation, and improving production efficiency.

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

[0026] like Figure 1-3 As shown in the embodiment of this application, an aluminum slag removal and deoxidation agent pelletizing device is disclosed, including a device body 1. A first drive mechanism 4 is provided on the side surface of the device body 1. The output end of the first drive mechanism 4 is connected to a pelletizing roller 6 through a rotating shaft. A first gear 5 is installed on the surface of the rotating shaft. Two first gears 5 are meshed and connected. A V-shaped plate 9 is welded to the upper surface of the inner bottom surface of the device body 1 through the vibration isolation spring support leg 12. A vibration motor 11 is installed on the lower surface of the V-shaped plate 9 through anti-loosening bolts. A filter hole 10 is opened on the surface of one side of the V-shaped plate 9.

[0027] The first drive mechanism 4 and the ball forming roller 6: The first drive mechanism 4 is fixed to the side surface of the device body 1 by bolts. The output shaft of the drive motor is keyed to the input shaft of the reducer. The output shaft of the reducer is rigidly connected to the rotating shaft of the ball forming roller 6 through a coupling. The rotating shaft passes through the side wall of the device body 1 and is supported at both ends by deep groove ball bearings. The bearing seats are welded and fixed to the body. The outer ends of the rotating shafts of the two ball forming rollers 6 are each equipped with a first gear 5. The two gears mesh laterally. The gear transmission ratio of 1:1 ensures that the two rollers rotate synchronously in opposite directions. The linear speed is consistent when extruding the raw material, avoiding slippage of the raw material or deformation of the ball due to the difference in rotation speed.

[0028] V-shaped plate 9 and device body 1: 4 sets of vibration isolation spring support legs 12 are welded to the inner bottom surface of device body 1. V-shaped plate 9 is fixed to the top of the support legs by bolts to form an elastic suspension structure. The lower surface of V-shaped plate 9 is fixed by anti-loosening bolts. When started, it generates a reciprocating vibration force perpendicular to the plate surface.

[0029] Inside the main body 1 and below the ball forming roller 6, a demolding rod 13 is installed. A rubber demolding pad 14 is installed on the surface of the demolding rod 13. A second gear 8 is installed on the surface of the demolding rod 13, and the second gear 8 is meshed with the first gear 5.

[0030] Ball-forming roller 6 and demolding rod 13: The demolding rod 13 is horizontally installed directly below the ball-forming roller 6, and both ends are fixed to the inner wall of the device body 1 through bearing seats. The second gear 8 is installed on the outer end of the demolding rod 13, which meshes with the first gear 5 on the rotating shaft of the ball-forming roller 6, ensuring that the rotation speed of the demolding rod 13 is 1.5 times that of the ball-forming roller 6, thereby optimizing the time difference of the "ball-demolding" action. The pad is made of neoprene rubber and is fixed to the surface of the demolding rod 13 by countersunk bolts. The gap between the working surface and the surface of the ball-forming roller 6 is controlled at 0.5-1mm, which ensures both flexible contact to peel off the deoxidizer from the balls and avoids hard friction damage to the roller surface grooves. The second drive mechanism 7 is bolted to the side surface of the device body 1. The output end of the second drive mechanism 7 is mounted with a crushing roller 3 via a rotating shaft. The surface of the crushing roller 3 is provided with protruding ridges, and the surface of the rotating shaft is mounted with a third gear 15. The two third gears 15 are meshed together.

[0031] The second drive mechanism 7 and the crushing roller 3: The second drive mechanism 7 is fixed to one side of the device body 1 by an L-shaped bracket. The drive motor is connected to the reducer. The output shaft of the reducer is connected to the rotating shaft of the crushing roller 3 by a universal coupling. The crushing roller 3 is horizontally installed below the feed bin 2 and upstream of the ball forming roller 6, with an axial distance of 150mm between it and the ball forming roller 6, to ensure that the crushed material falls directly into the gap of the ball forming roller 6. The surface of the crushing roller 3 is milled with 4 sets of spiral ridges, which are fixed to the roller body by a heat fitting process. The gap between the ridges and the inner wall of the device body 1 is controlled at 3-5mm to prevent large pieces of material from getting stuck.

[0032] Both the first drive mechanism 4 and the second drive mechanism 7 are composed of a drive motor and a reducer, with the output end of the drive motor connected to the reducer.

[0033] The first drive mechanism 4 and the second drive mechanism 7 can precisely adjust the speed and torque according to the requirements of different processes such as pelletizing and crushing, which can ensure pelletizing pressure and control crushing force, thereby improving the adaptability of the equipment. The upper surface of the device body 1 is welded with a feed bin 2, and the feed bin 2 has a cone-shaped funnel structure.

[0034] Feeding bin 2: Feeding bin 2 adopts an inverted truncated cone structure, with the inner wall polished and welded to the upper surface of the device body 1. The cone angle design increases the acceleration of material sliding, causing the material to fall quickly.

[0035] The upper surface of the V-shaped plate 9 is adhered with a polyurethane buffer pad, and the upper surface of the polyurethane buffer pad is provided with through holes for use with the filter holes 10.

[0036] Filter holes 10 and polyurethane buffer pad: V-shaped plate 9 has filter holes 10 on one side, and a polyurethane buffer pad is attached above the filter holes 10. The elevator has through holes of the same size. The buffer pad is bonded to V-shaped plate 9 with high-temperature resistant adhesive. The edge extends beyond the area of ​​filter holes 10 to form a buffer boundary. When the spherical deoxidizer (5-8mm in diameter) falls onto the buffer pad, the elastic deformation of the pad is about 2mm, and the impact duration is extended from 0.01s to 0.05s. According to the momentum theorem FΔt=Δp, the peak impact force is reduced from 8N ​​to below 3N, avoiding the sphere from breaking due to brittle fracture.

[0037] The lower surface of the device body 1 is welded with a support leg 16, and the lower surface of the support leg 16 is provided with a shock-absorbing and anti-slip pad.

[0038] Support legs 16 and shock-absorbing and anti-slip pads: Four sets of support legs 16 are welded to the lower surface of the device body 1. Shock-absorbing and anti-slip pads are pasted on the bottom of the support legs 16 and fixed by countersunk bolts to prevent the equipment from shifting and improve working stability.

[0039] An integrated controller 17 is bolted to the side surface of the device body 1, and a protective pad is attached to the back of the integrated controller 17.

[0040] Integrated controller 17: The integrated controller 17 is fixed to the side wall of the device body 1 by bolts, and an EVA anti-slip pad is attached to the back. Its internal PLC is connected to the first drive mechanism 4, the second drive mechanism 7, and the vibration motor 11 through shielded cables. The ball roller 6, the crushing roller 3 and the vibration motor 11 are linked by the integrated controller 17. The speed, vibration frequency and other parameters are automatically adjusted according to the real-time status of the raw materials to improve the separation adaptability.

[0041] The working principle of the aluminum slag removal and deoxidizing agent pelletizing device in this embodiment is as follows: The aluminum slag removal and deoxidizing agent raw material is poured from the top of the gold hopper and falls rapidly due to gravity using the cone-shaped funnel structure. When the raw material falls to the crushing roller 3, the second drive mechanism 7 drives the crushing roller 3 to rotate. The convex edge shears, squeezes and crushes the large pieces of raw material, refining them. The crushed raw material falls through the roller gap onto the pelletizing roller 6, reducing the squeezing load on the pelletizing roller and preventing equipment vibration caused by the impact of large pieces of material. The first drive mechanism 4 drives the two pelletizing rollers 6 to rotate synchronously in opposite directions through gear meshing. The raw material is gradually squeezed in the space formed between the rollers. The ball-and-socket structure on the surface of the pelletizing roller 6 compresses and shapes the raw material into spherical deoxidizing agents of the specified size. The demolding rod 13 meshes with the pelletizing roller 6 through the second gear 8, rotating at 1.5 times the speed of the pelletizing roller 6. The roller rotates rapidly. When the sphere is formed and rotates with the roller surface to the demolding position, the rubber demolding pad 14 flexibly contacts the roller surface. It uses friction and mechanical thrust to peel the sphere off, preventing the sphere from sticking to the roller surface and forming clumps. The demolding action is synchronized with the sphere forming process to ensure production continuity. After demolding, the sphere and a small amount of sheet material fall onto the surface of the V-shaped plate 9. The vibrating single-machine drive of the V-shaped plate 9 generates reciprocating vibration perpendicular to the plate surface. The spherical material rolls and bounces during the vibration and slides down the inclined plane, realizing the separation of the sphere and sheet. The filter holes 10 on the surface of the V-shaped plate 9 are aligned with the through holes of the polyurethane buffer pad. Qualified spherical material rolls down along the inclined plane of the V-shaped plate 9, while unqualified spherical material and impurities fall through the filter holes 10 to the discharge port. The buffer pad absorbs the impact of the falling sphere through elastic deformation, preventing the sphere from breaking due to collision and improving the qualified rate of finished spheres.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
