Abstract
Description
An apparatus for producing and processing alloy materials for electric furnaces Technical Field
[0001] This utility model relates to the field of alloy material preparation technology, and in particular to an alloy material production and processing device for electric furnaces. Background Technology
[0002] In the production and processing of alloy materials for electric furnaces, the grinding and mixing of raw materials is one of the key processes, and its quality directly affects the performance of the final alloy product. Traditional grinding equipment usually uses ball mills or roller presses, but these devices have the following drawbacks:
[0003] 1. Ball mills rely on the random collision of steel balls and raw materials to achieve grinding, with an energy utilization rate of less than 30%, and the uniformity of the ground particles is poor. Although roller presses are more efficient, they have strict requirements on parameters such as the moisture content and hardness of the raw materials and are not adaptable enough.
[0004] 2. Traditional equipment usually requires an additional mixer, which makes the process complex and the staged processing can easily introduce pollution risks;
[0005] 3. The existing grinding equipment cylinder is mostly a closed welded structure. The replacement of internal wear parts (such as grinding discs and liners) requires complete disassembly, resulting in downtime of more than 48 hours.
[0006] 4. Single-stage grinding mechanisms are difficult to achieve gradient crushing of raw materials, especially for high-hardness alloy raw materials (such as tungsten carbide), where over-crushing or insufficient crushing often coexist.
[0007] To address the aforementioned issues, there is an urgent need to develop a processing device that integrates grinding and mixing functions, consumes little energy, and is easy to maintain, in order to meet the requirements for efficient production of electric furnace alloy materials. Summary of the Invention
[0008] In order to overcome the shortcomings of the prior art, this utility model discloses an alloy material production and processing device for electric furnaces. This utility model can not only perform efficient and high-quality step-by-step grinding of alloy material raw materials, but also simultaneously perform mixing treatment, which effectively improves the processing efficiency of alloy material raw materials.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] An alloy material production and processing device for electric furnaces includes a cylindrical body. A feed inlet and a motor are located on the upper part of the body. The output end of the motor has a rotating shaft that extends through the body and is coaxial with it. A first grinding mechanism for grinding and mixing raw materials is located on the upper part of the rotating shaft within the body. The first grinding mechanism includes a material distribution hood, a grinding disc, and a collection hopper. The grinding disc is coaxially fixed with the rotating shaft and rotates synchronously with it. A grinding gap is formed between the annular surface of the grinding disc and the inner wall of the body. The material distribution hood is located on the upper part of the grinding disc and is used to guide and convey the raw materials into the grinding gap. The collection hopper is located on the lower part of the grinding disc and is used to collect and convey raw materials that fall into the grinding gap. A second grinding mechanism with the same structure as the first grinding mechanism is located below the first grinding mechanism and is used for secondary grinding and mixing of the raw materials processed by the first grinding mechanism. The diameter of the grinding disc in the second grinding mechanism is larger than that in the first grinding mechanism. A discharge port for discharging the ground raw materials is located at the lower part of the body.
[0011] Furthermore, the feed inlet is located in the middle of the upper surface of the cylinder, and a mounting base is provided above the feed inlet. The motor is located on the upper part of the mounting base, and a feeding hopper connected to the feed inlet is provided below the mounting base. The rotating shaft passes through the feeding hopper and the feed inlet into the cylinder. A feeding port connected to the feeding hopper is provided on the side of the mounting base.
[0012] Furthermore, the material hood is conical with open structures at both the top and bottom. The rotating shaft passes through the material hood and is coaxially arranged with it. The diameter of the upper opening of the material hood matches the diameter of the rotating shaft, and the diameter of the lower opening of the material hood matches the diameter of the grinding disc.
[0013] Furthermore, the hopper is inverted conical in shape and has an open structure at both the top and bottom. The rotating shaft passes through the hopper and is coaxially arranged with the hopper. The diameter of the upper opening of the hopper is matched with the inner diameter of the cylinder, and the lower opening of the hopper forms a discharge port with a diameter larger than that of the rotating shaft.
[0014] Furthermore, the rotating shaft located inside the hopper is equipped with spiral blades.
[0015] Furthermore, the grinding disc ring surface is provided with an expanding inclined surface that is arranged circumferentially along the grinding disc.
[0016] Furthermore, the shaft body is provided with a mounting plate that is coaxial with the shaft and is used to limit and support the grinding disc.
[0017] Furthermore, the discharge port and the inlet are arranged vertically and vertically, and a discharge pipe is provided between the discharge port and the discharge port at the lower end of the hopper in the second grinding mechanism. A support rod for rotating the end of the rotating shaft is provided inside the discharge pipe.
[0018] Furthermore, the cylinder is formed by two semi-cylindrical movable cylinders and a fixed cylinder. The rotating shaft, the first grinding mechanism, the second grinding mechanism, and the feeding pipe are all installed in the fixed cylinder. The upper and lower ends of the opposite surfaces of the movable cylinder and the fixed cylinder are respectively provided with corresponding upper and lower half-ring openings. The two corresponding upper half-ring openings are fastened together to form the feed port, and the two corresponding lower half-ring openings are fastened together to form the discharge port.
[0019] Furthermore, the grinding disc ring surface is provided with a grinding layer arranged along the circumference of the grinding disc, and the inner walls of both the movable cylinder and the fixed cylinder are provided with mounting grooves that correspond to the grinding disc and are semi-circular in structure along the inner wall. Both ends of the mounting groove are open structures, and the mounting groove is provided with a grinding plate that is adapted to the mounting groove and corresponds to the grinding layer of the grinding disc ring surface.
[0020] Compared with the prior art, the beneficial effects of this utility model are: through the grinding gap formed between the grinding disc and the inner wall of the cylinder, the raw materials can be ground and crushed efficiently and with high quality, which greatly saves energy and cost compared with the traditional ball mill grinding method.
[0021] By setting up a material hood, not only can the raw materials be effectively dispersed, but they can also be guided and conveyed, allowing them to quickly and accurately roll into the grinding gap, providing strong support for the subsequent grinding and crushing of the raw materials.
[0022] By setting up a collection hopper, not only can the raw materials after grinding and crushing be collected and mixed, but it also provides strong support for the centralized transportation of the raw materials in the future.
[0023] By setting up spiral blades, not only can the raw materials in the hopper be mixed, but the subsequent feeding of the raw materials is also facilitated.
[0024] By setting up multiple grinding mechanisms, the raw materials can be ground and mixed in stages, which greatly improves the grinding and mixing quality of the raw materials and provides strong support for the high-quality production of subsequent alloy materials.
[0025] By setting up a feed pipe and support rod, the stability of the rotating shaft can be greatly improved, providing strong support for the efficient and high-quality grinding of the grinding mechanism.
[0026] By setting an openable cylinder, as well as a grinding layer and grinding plates, it not only facilitates the subsequent cleaning and maintenance of the cylinder's interior, but also allows for inspection and maintenance, effectively extending the service life of the device and ensuring the quality of grinding and mixing.
[0027] This invention not only enables efficient and high-quality step-by-step grinding of alloy raw materials, but also allows for simultaneous mixing, effectively improving the processing efficiency of alloy raw materials.

[0032] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation.
[0033] Please refer to Figures 1-3 in the specification. This utility model provides a technical solution:
[0034] Example 1: An alloy material production and processing device for electric furnaces includes a cylindrical body 7. The upper part of the body 7 is provided with a feed inlet 5 and a motor 1. Specifically, the feed inlet 5 is located in the middle of the upper surface of the body 7. The upper part of the feed inlet 5 is provided with a mounting base 2. The motor 1 is located on the upper part of the mounting base 2. The lower part of the mounting base 2 is provided with a feeding hopper 4 that communicates with the feed inlet 5. The side of the mounting base 2 is provided with a feeding port 3 that communicates with the feeding hopper 4.
[0035] The output end of the motor 1 is provided with a rotating shaft 6 coaxially arranged with the cylinder 7. The rotating shaft 6 passes through the feeding hopper 4 and the feed inlet 5 into the cylinder 7. The upper part of the rotating shaft 6 inside the cylinder 7 is provided with a first grinding mechanism for grinding and mixing the raw materials. Specifically, the first grinding mechanism includes a material hood 8, a grinding disc 9 and a collection hopper 10. The grinding disc 9 is coaxially fixed with the rotating shaft 6 and rotates synchronously with it. The annular surface of the grinding disc 9 and the inner wall of the cylinder 7 form a grinding gap. In order to ensure that the grinding disc 9 is installed firmly and stably, the shaft of the rotating shaft 6 is provided with a mounting plate 18 coaxially arranged with the rotating shaft 6 and used to limit and support the grinding disc.
[0036] The material hood 8 is conical and has an open structure at both the top and bottom. The material hood 8 is located on the upper part of the grinding disc 9. The rotating shaft 6 passes through the material hood 8 and is coaxial with the material hood 8. The diameter of the upper opening of the material hood 8 is matched with the diameter of the rotating shaft 6, and the diameter of the lower opening of the material hood 8 is matched with the diameter of the grinding disc 9. The raw material falls from the feed port 5 to the upper part of the material hood 8 and can smoothly roll into the grinding gap for grinding and crushing through the diffusion guidance on the upper surface of the material hood 8. In order to ensure that the raw material can smoothly enter the grinding gap for grinding, the grinding disc 9 has an expanding inclined surface 16 along the circumference of the grinding disc 9.
[0037] The collecting hopper 10 is inverted cone shape and has an open structure at both the top and bottom. The collecting hopper 10 is located at the bottom of the grinding disc 9. The rotating shaft 6 passes through the collecting hopper 10 and is coaxial with the collecting hopper 10. The diameter of the upper opening of the collecting hopper 10 is adapted to the inner diameter of the cylinder 7. The lower opening of the collecting hopper 10 forms a discharge port 12 with a diameter larger than that of the rotating shaft 6. After grinding and crushing, the raw materials are collected and mixed by the collecting hopper 10 and then discharged downward through the discharge port 12.
[0038] The lower part of the first grinding mechanism is provided with a second grinding mechanism, which has the same structure as the first grinding mechanism and is used to perform secondary grinding and mixing of the raw materials processed by the first grinding mechanism. The diameter of the grinding disc 9 in the second grinding mechanism is larger than that in the first grinding mechanism. By using grinding discs 9 of different sizes, different grinding gaps can be formed with the inner wall of the cylinder 7, thereby realizing the step-by-step grinding and mixing of the raw materials. The lower part of the cylinder 7 is provided with an outlet 15, which is set vertically and vertically corresponding to the feed inlet 5 and is used to discharge the ground raw materials.
[0039] In Example 2, although the raw materials can be mixed after being crushed by the grinding disc 9 and falling into the collecting hopper 10, the mixing effect is not ideal. In order to improve the mixing effect of the raw materials, a spiral blade 11 is provided on the shaft of the rotating shaft 6 located in the collecting hopper 10. The spiral blade 11 is a bidirectional spiral blade with protrusions or grooves on its surface. The bidirectional spiral blade (one section rotates left and one section rotates right) increases shearing and mixing while pushing the material. The protrusions or grooves on the blade surface enhance the tumbling and mixing of the raw materials. The spiral blade 11 can also provide strong support for the smooth downward discharge of the subsequent raw materials.
[0040] In Example 3, both the first and second grinding mechanisms are mounted on the rotating shaft 6. Since the lower end of the rotating shaft 6 is suspended and not fixed, the rotating shaft 6 is prone to shaking during the grinding and crushing process. This not only affects the grinding effect of the raw materials, but also easily leads to damage to the first or second grinding mechanism. In order to ensure the vertical stability of the rotating shaft 6, a feeding pipe 13 is provided between the feeding port 12 and the discharge port 15 at the lower end of the collecting hopper 10 in the second grinding mechanism. A support rod 14 for rotating support of the end of the rotating shaft 6 is provided in the feeding pipe 13.
[0041] In Example 4, to facilitate subsequent cleaning of the interior of the cylinder 7 and maintenance of the first and second grinding mechanisms, the cylinder 7 is formed by the fastening of two semi-cylindrical movable cylinders 20 and a fixed cylinder 24. The rotating shaft 6, the first grinding mechanism, the second grinding mechanism, and the feed pipe 13 are all installed inside the fixed cylinder 24. The motor 1 and the mounting base 2 are installed on the upper part of the fixed cylinder 24. The upper and lower ends of the opposite surfaces of the movable cylinder 20 and the fixed cylinder 24 are respectively provided with corresponding upper half-ring openings 19 and lower half-ring openings 23. The two corresponding upper half-ring openings 19 are fastened together to form the feed inlet 5, and the two corresponding lower half-ring openings 23 are fastened together to form the feed inlet 5. The discharge port 15 is formed. The grinding disc 9 has a grinding layer 17 arranged around the circumference of the grinding disc 9. The inner walls of the movable cylinder 20 and the fixed cylinder 24 are provided with mounting grooves 21 that correspond to the grinding disc 9 and are semi-circular in structure along the inner wall. Both ends of the mounting groove 21 are open. The mounting groove 21 is provided with a grinding plate 22 that is adapted to the mounting groove 21 and corresponds to the grinding layer 17 on the circumference of the grinding disc 9. During the inspection and maintenance process, the interior of the movable cylinder 20 and the fixed cylinder 24 can be cleaned by simply opening the movable cylinder 20. Maintenance can also be performed by applying a tungsten carbide coating to the grinding layer 17 or by directly replacing the grinding plate 22.
