Description

Technical Field

[0001] This utility model relates to the field of metallurgical material processing technology, specifically to a high-efficiency mixing device for metallurgical materials. Background Technology

[0002] In the modern metallurgical industry, the uniform mixing and efficient processing of materials are key to ensuring the stability of the smelting process and improving product quality. As the metallurgical industry develops towards refinement and efficiency, various metal powders, auxiliary materials and intermediate products need to be fully stirred in multiple processes, from ore pretreatment to alloy smelting, to ensure that the material composition is uniformly distributed and the reaction is fully carried out, thereby reducing energy consumption and improving resource utilization. As the core device for realizing this process, the performance of stirring equipment directly affects the overall efficiency and cost control of metallurgical production. Therefore, the optimization and upgrading of stirring equipment has always been an important direction for technological research and development in the industry.

[0003] Currently, most mixing equipment used in the metallurgical field operates primarily through mechanical mixing. Its basic structure typically includes a mixing tank, a drive motor, a mixing shaft, and mixing blades. During operation, the drive motor rotates the mixing shaft, causing the mixing blades fixed on the shaft to move in a circular motion within the tank. Through the contact, shearing, and pushing action between the blades and the materials, relative motion occurs between the materials, thereby achieving the mixing purpose. Due to its simple structure and convenient operation, this type of equipment is widely used in small and medium-scale metallurgical production scenarios and can meet the mixing needs of general materials. However, existing mechanical mixing equipment often suffers from insufficient mixing uniformity when processing high-viscosity, easily agglomerated metallurgical materials. Due to the inherent viscosity of the material or the adsorption force between particles, local agglomeration is easily formed during the mixing process, which is difficult to completely break up by mechanical shearing of the blades alone. At the same time, the material flow path is relatively fixed under traditional mixing methods, and the mixing speed of the material in different areas of the tank varies, resulting in low overall mixing efficiency. This not only prolongs the processing time but may also affect the stability of subsequent smelting reactions due to uneven mixing, making it difficult to meet the higher requirements of modern metallurgical industry for material processing precision and efficiency. Therefore, we propose a high-efficiency mixing equipment for metallurgical materials. Utility Model Content

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.

[0016] Please see Figure 1-4This embodiment provides a technical solution: a high-efficiency mixing device for metallurgical materials, including a mixing tank 1. A maintenance door 8 is hinged to the left end of a doorway on the front side wall of the mixing tank 1. (The maintenance door 8 has a rubber sealing ring along its edge. A mechanical lock is provided between the right end of the maintenance door 8 and the right end of the mixing tank 1. The mechanical lock is a conventional mechanical lock in the prior art, mainly composed of a lock body, a latch, a latch, a keyhole, and a spring structure. The lock body is fixedly installed at the lower right end of the mixing tank 1, and the latch can extend and retract within the lock body, cooperating with the latch fixed at the lower end of the maintenance door 8 to achieve locking.) An observation window is provided in the middle of the maintenance door 8. A control switch group 9 is provided on the right side of the mixing tank 1. The input end of the control switch group 9 is electrically connected to an external power source. An installation plate 7 is provided at the upper interior of the mixing tank 1. A feed inlet is provided at the right end of the outer arc surface of tank 1. A feed pipe 3 is provided inside the feed inlet. A valve 4 is connected in series in the middle of the feed pipe 3. An electric valve 6 is connected in series in the middle of the discharge pipe 5 provided at the lower end of the mixing tank 1. The input end of the electric valve 6 is electrically connected to the output end of the control switch group 9. Vents are provided at both the upper and lower ends of the outer arc surface of the mixing tank 1. Micro-perforated plates are provided inside the vents. When the valve 4 in the middle of the feed pipe 3 is opened, the metallurgical material enters the mixing tank 1 through the feed pipe 3. After the material is fed in, the valve 4 is closed. The worker observes the mixing status of the metallurgical material in the mixing tank 1 through the observation window in the middle of the maintenance door 8. After the mixing is completed, the electric valve 6 is opened through the control switch group 9, and the uniformly mixed material is discharged through the discharge pipe 5. This provides a mixing area for the metallurgical material and also includes a mixing mechanism 2. The stirring mechanism 2 includes a stirring shaft 21, stirring blades 22, branch pipes 23, and an air outlet pipe 24. The stirring shaft 21 is rotatably connected to the middle of the mounting plate 7 (the stirring shaft 21 and the middle of the mounting plate 7 are rotatably connected via a sealed bearing). The stirring mechanism 2 also includes a servo motor 26, which is located at the upper end of the stirring tank 1. The output shaft of the servo motor 26 is fixedly connected to the center of the upper end face of the stirring shaft 21. The input end of the servo motor 26 is electrically connected to the output end of the control switch group 9. The lower end of the stirring shaft 21 is provided with symmetrically distributed stirring blades 22. The branch pipe 23 is located in the branch opening at the upper end of the stirring shaft 21 and is connected to the air supply channel 10 opened inside the stirring shaft 21. The air outlet pipe 24 is fixedly connected to the stirring tank 1. On the upper left side wall of tank 1, the stirring mechanism 2 also includes a blower 27. The blower 27 is located at the upper end of the stirring tank 1. The upper end of the air outlet pipe 24 is fixedly connected to the air outlet of the blower 27. The input end of the blower 27 is electrically connected to the output end of the control switch group 9. The lower end of the air outlet pipe 24 is located inside the stirring tank 1 and is configured to cooperate with the upper end of the branch pipe 23. The stirring mechanism 2 also includes a circular nozzle 25. The circular nozzle 25 is threadedly connected to the lower end of the air outlet pipe 24 and is used in cooperation with the upper end of the branch pipe 23. (The circular nozzle 25 is located on the circular path formed by rotating around the stirring shaft 21 at the upper end of the branch pipe 23. The upper end of the branch pipe 23 is provided with a corresponding clearance groove for the circular nozzle 25. The circular nozzle 25 has a circular nozzle outlet structure.) The blown airflow is columnar, with concentrated wind force and strong impact. Each of the symmetrically distributed air inlets at the lower end of the stirring shaft 21 is equipped with a filter plate 211. When the equipment is started via the control switch group 9, the servo motor 26 and blower 27 are powered on and begin operation. The output shaft of the servo motor 26 drives the stirring shaft 21 to rotate intermittently 360 degrees (during the rotation of the stirring shaft 21, the stirring blades 22 at its lower end tumble and stir the material). The branch pipe 23 at the upper end of the stirring shaft 21 is located directly below the circular nozzle 25 at the lower end of the air outlet duct 24. When the stirring shaft 21 stops rotating, the airflow finally exits from the symmetrically distributed air inlets at the lower end of the stirring shaft 21 (this is pre-controlled by the controller of the servo motor 26, setting the intermittent rotation of the servo motor 26's output shaft). The stopping point is when the branch pipe 23 rotates to the lower end of the outlet pipe 24. Simultaneously, workers can observe the interior of the mixing tank 1 in real time through the observation window in the middle of the maintenance door 8. This ensures that when the branch pipe 23 and the lower end of the outlet pipe 24 are precisely aligned, the servo motor 26 can accurately achieve intermittent stopping, thus ensuring that the airflow delivered by the outlet pipe 24 can stably pass through the branch pipe 23 into the air supply channel 10 inside the mixing shaft 21. Ultimately, the airflow acts on the metallurgical materials through the air outlet. After being filtered by the filter screen 211 (to prevent material particles from entering the air supply channel 10 and causing blockage), the airflow directly acts on the metallurgical materials in the mixing tank 1, causing the materials to disperse under the impact of the airflow and reducing agglomeration. When the mixing shaft 21 rotates again, the circular nozzle 25 separates from the branch pipe 23, and the air supply stops.Excess gas inside the mixing tank 1 is discharged through the exhaust vent on the outer arc surface and the micro-perforated plate, preventing excessive gas pressure inside the tank and ensuring efficient mixing of metallurgical materials.

[0017] The working principle of the high-efficiency mixing equipment for metallurgical materials provided by this utility model is as follows: Open valve 4 in the middle of the feed pipe 3, and the metallurgical material enters the mixing tank 1 through the feed pipe 3. After the material is fed in, close valve 4 and start the equipment via control switch group 9. The servo motor 26 and blower 27 are powered on and begin working. The output shaft of the servo motor 26 drives the mixing shaft 21 to rotate intermittently 360 degrees (during the rotation of the mixing shaft 21, the mixing blades 22 at its lower end tumble and mix the material). The branch pipe 23 at the upper end of the mixing shaft 21 is located directly below the circular nozzle 25 at the lower end of the air outlet duct 24. When the mixing shaft 21 stops rotating, the airflow finally blows out from the symmetrically distributed air outlets at the lower end of the mixing shaft 21 (this is pre-controlled by the controller of the servo motor 26, setting the intermittent stop point of the output shaft of the servo motor 26 to the position where the branch pipe 23 rotates to the lower end of the air outlet duct 24). Simultaneously, workers can observe the internal condition of the mixing tank 1 in real time through the observation window in the middle of the maintenance door 8, ensuring that the branch pipe 23 and the air outlet... When the lower end of pipe 24 is precisely aligned, servo motor 26 can accurately achieve intermittent stopping, thereby ensuring that the airflow delivered by outlet pipe 24 can stably enter the air supply channel 10 inside the stirring shaft 21 through branch pipe 23, and finally act on the metallurgical material through the air outlet. After being filtered by filter screen plate 211 (to prevent material particles from entering the air supply channel 10 and causing blockage), it directly acts on the metallurgical material in the mixing tank 1, causing the material to disperse under the impact of airflow and reducing agglomeration. When the stirring shaft 21 rotates again, the circular nozzle 25 and When branch pipe 23 is separated, air supply is suspended. Workers can observe the mixing status of metallurgical materials in mixing tank 1 through the observation window in the middle of maintenance door 8. After mixing is completed, the electric valve 6 is opened through control switch group 9, and the uniformly mixed material is discharged through discharge pipe 5. If cleaning or maintenance of the equipment is required, maintenance door 8 can be opened (unlocked by mechanical lock) to maintain components such as mixing blades 22 and filter screen 211 inside mixing tank 1. Excess gas in mixing tank 1 is discharged through the exhaust port on the outer arc surface and the micro-perforated plate to avoid excessive gas pressure inside the tank.

[0018] It is worth noting that the servo motor 26 disclosed in the above embodiments can be a conventional servo motor, the blower 27 can be a CZR series centrifugal blower, and the electric valve 6 can be a conventional electric valve. The control switch group 9 is provided with control buttons that correspond one-to-one with the servo motor 26, the blower 27 and the electric valve 6 and are used to control their switching.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
