Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment technology, specifically to a homogenization feeding device for powder materials. Background Technology

[0002] Multi-tube reduction furnaces are used in the reduction process of alloy production to reduce metal powder. Typically, boats are used to hold the metal powder raw materials, and the powder is transported through various process stages by moving the boats. To ensure production quality, the metal powder raw materials need to be evenly distributed in the boats before the reduction process. Existing technologies generally use shaking or scraping methods to homogenize the metal powder raw materials, but these methods have a certain degree of randomness, and when the boats are large, localized accumulation of metal powder raw materials can easily occur. Utility Model Content

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] See Figure 1-5 As shown in the preferred embodiment of this utility model, a powder material homogenization feeding device is provided, including a feeding hopper 1, a vibrating conveyor 2, a weighing device 3, and a shaking device 4. The feeding hopper 1 extends vertically, with a feeding port 11 at the upper end and a discharge port 12 at the lower end. The powder material can be fed manually or automatically through the feeding port 11. The lower end of the feeding hopper 1 gradually narrows to allow the powder material to collect downwards. The vibrating conveyor 2 includes a vibrating device 21 and a conveying pipe 22 connected to the vibrating device. The vibrating conveyor 2 is similar to a vibrating plate, and the forward conveying of the powder material in the conveying pipe 22 is achieved by the vibration of the vibrating device 21. In this embodiment, the vibrating device 21 is an electromagnetic vibrator. The conveying pipe 22 has a feed end 221 and a discharge end 222. The feed end 221 of the conveying pipe 22 is located below the feed hopper 1 and connected to the discharge port 12. Except for the feed end 221 and the discharge end 222, the conveying pipe 22 is a closed pipe, so the powder material can be prevented from being scattered out of the conveying pipe 22 due to vibration.

[0024] The weighing device 3 includes a first loading tray 31 for loading the boat 5, and the shaking device 4 includes a second loading tray 41 for loading the boat 5. The first loading tray 31 and the second loading tray 41 are arranged collinearly to form a path for conveying the boat 5 from the weighing device 3 to the shaking device 4 (the conveying direction is in the direction of...). Figure 1 (represented by T in this embodiment) In this embodiment, the distance between the first material tray 31 and the second material tray 41 is less than the length of the boat 5. Therefore, during the process of conveying the boat 5 from the weighing device 3 to the shaking device 4, the boat 5 enters the shaking device 4 before leaving the weighing device 3. In other embodiments, if the distance between the first material tray 31 and the second material tray 41 is greater than the length of the boat 5, a transition platform for carrying the boat can be further provided between the first material tray 31 and the second material tray 41.

[0025] The conveying of the boat 5 is driven by a transfer mechanism (not shown in the figure). For example, the transfer mechanism can be a pushing mechanism or a pulling mechanism. The transfer mechanism applies force to the boat 5 to achieve its conveying. The power source of the transfer mechanism can be a cylinder, hydraulic cylinder, motor, or other driving device. The first loading tray 31 and the second loading tray 41 can actually be part of the conveying line of the boat 5. That is, the boat 5 can be first fed into the first loading tray 31 from upstream, then fed into the second loading tray 41 from the first loading tray 31, and finally discharged from the second loading tray 41. Multiple transfer mechanisms can be arranged. For example, in this embodiment, a cylinder-driven pushing mechanism is provided upstream of the first loading tray 31 and upstream of the second loading tray 41 as a transfer mechanism. This mechanism is used to realize the process of the boat 5 being fed from the first loading tray 31 into the second loading tray 41 and the process of the boat 5 being fed out of the second loading tray 41, respectively. Of course, this arrangement is because the extension and retraction stroke of the cylinder is limited. If the movement stroke of the transfer mechanism is long enough, it is also feasible to set only one transfer mechanism. For example, the transfer mechanism has a sliding track spanning the weighing device 3 and the shaking device 4, and a sliding block on the sliding track to push the boat 5 for transport. The transfer mechanism can be configured to be close to or away from the boat 5 to avoid affecting the weighing and shaking operation of the boat 5. If multiple transfer mechanisms are used, this can also prevent the front transfer mechanism from blocking the transport of the rear boat 5.

[0026] The transfer mechanism for the boat 5 is set to move in steps, meaning that the boat 5 can stop on the weighing device 3 or the shaking device 4 during the transfer process to achieve weighing and shaking. If a multi-cylinder driven push mechanism is used as the transfer mechanism, the transfer mechanism cannot continue to drive the boat 5 when the cylinders reach their maximum extension stroke, causing the boat 5 to stop. If a continuously moving transfer mechanism is used, such as the sliding rail and sliding block scheme described above, the sliding block can be controlled by electrical control technology to pause at any sliding position, thereby causing the boat 5 to stop.

[0027] In summary, the boat 5 can be conveyed stepwise between the weighing device 3 and the shaking device 4. The discharge end 222 of the conveying pipe 22 is located above the weighing device 3. Through the vibrating conveyor 2, the powder material falling into the conveying pipe 22 can be conveyed forward to the boat 5 on the weighing device 3. The first loading tray 31 is suspended. The weighing device 3 also includes a weighing sensor 32 fixedly connected to the first loading tray 31. This design allows the powder material falling into the boat 5 to be weighed. Furthermore, with the feedback from the weighing sensor 32, the start-up and working frequency of the vibrating conveyor 2 can be controlled by electrical control technology. On the one hand, the vibrating conveyor 2 can be stopped after the weighing device 3 has weighed a certain weight of powder material. On the other hand, the working frequency of the vibrating conveyor 2 can be reduced when the weight of the powder material is about to reach a predetermined value, thereby making the weighed powder material more accurate.

[0028] See Figure 2 and Figure 3 The discharge end 222 of the conveying pipe 22 is provided with a serrated material distribution port 220. The material distribution port 220 allows the powder material falling onto the boat 5 to be more dispersed, effectively reducing the accumulation of powder material on the boat 5, and making it more conducive to the shaking device 4 to shake the powder material. Furthermore, a baffle 23 is provided in the conveying pipe 22 to scrape the powder material conveyed in the conveying pipe 22. It is foreseeable that some of the powder material falling from the feed hopper 1 into the conveying pipe 22 will always accumulate. By scraping the powder material with the baffle 23, the powder material can be more evenly dispersed in the conveying pipe 22, improving the material distribution effect of the material distribution port 220. In this embodiment, the height of the baffle 23 is adjustable, thereby flexibly adjusting the opening of the scraping port formed by the baffle 23 and the conveying pipe 22. In this embodiment, the baffle 23 is connected to the conveying pipe 22 by adjusting screws to achieve its height adjustment.

[0029] See Figure 4 and Figure 5 The shaking device 4 includes a fixed frame 40, a sliding frame 42 slidably connected to the fixed frame 40, and a drive mechanism 43 fixedly connected to the fixed frame 40. The second material tray 41 and the sliding frame 42 are fixedly connected. The drive mechanism 43 and the sliding frame 42 are drively connected to drive the sliding frame 42 to slide back and forth on the fixed frame 40. Thus, when the boat 5 is carried by the second material tray 41, activating the drive mechanism 43 can achieve the shaking of the powder material. The sliding of the sliding frame 42 can be small to prevent the boat 5 from detaching from the second material tray 41. Furthermore, a liftable top cover 44 is provided on the sliding frame 42 to cover the boat 5, indicating the release of powder material.

[0030] The specific type of powder raw material is not limited in this embodiment. Different powders can be fed using the powder material homogenization feeding device of this embodiment, but the application process should be adjusted according to the characteristics of the powder (e.g., particle size).

[0031] The powder material homogenization feeding device provided in this embodiment can be used in a reduction furnace system to achieve homogenization of metal powder raw materials, which are then reduced by the reduction furnace. It can also be applied to other processing systems that require homogenization of powder materials.
