Description

Technical Field

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

[0002] In the rare earth metal electrolysis process, rare earth metals need to be mixed in a certain proportion before being added to the electrolysis furnace for electrolysis. The material added to the electrolysis furnace is in powder form. During the production process, the metal powder is automatically added to the mixer in a certain proportion for mixing, and then packaged into the material bucket according to a specific weight. After the proportioned and mixed material is added to the feeder by hand according to experience, it is finally added to the electrolysis furnace by the feeder.

[0003] Traditional feeders use a vacuum feeder at the top to suck materials into the feeder. This method has a long suction time. Furthermore, even if the vacuum feeder has a backflushing function, it is prone to clogging during use, and this happens frequently. The vacuum feeder is installed at the top, and its installation position is basically close to the electrolysis furnace. The electrolysis furnace has a high temperature, and disassembling the vacuum feeder requires climbing to work under high temperature conditions, which does not guarantee the safety of maintenance work. In addition, the method of manually hoisting the material-filled bucket to the top of the feeder and then pouring it into the feeder also has safety hazards. Moreover, the process of adding the mixed materials into the feeder under gravity generates a lot of dust, which can easily lead to waste of raw materials and pollution of the working environment. Utility Model Content

[0004] In view of this, the present invention provides a powder feeding device to solve the problem that the feed inlet of the existing feeder generates a large amount of dust during the feeding process, which easily leads to waste of raw materials and pollution of the working environment.

[0005] This utility model provides a powder feeding device, including:

[0006] Feeding frame;

[0007] A feeding bin is located at the upper end of the feeding frame. The top of the feeding bin has a feeding port, and the inner wall of the feeding port is provided with an inflatable sealing part.

[0008] A feeding assembly is connected to the discharge end of the feeding hopper and is used to output the material in the feeding hopper;

[0009] A material distribution pipe is installed on the feeding frame. The inlet end of the material distribution pipe is used to receive the material output by the feeding assembly, and the outlet end of the material distribution pipe is used to add the material into the electrolysis furnace.

[0010] The powder feeding device according to this utility model has at least the following beneficial effects:

[0011] By providing an inflatable, expandable sealing section on the inner wall of the feed inlet, after the open end of the material bucket containing the proportioned and mixed material is inserted into the feed inlet, the sealing section inflates and expands, filling and sealing between the outer side of the open end of the material bucket and the inner side of the feed inlet. This ensures that when the material bucket is opened and the material is added to the feeding hopper by gravity, the material will not leak from the connection between the open end of the material bucket and the feed inlet to the outside, causing dust to fly. This avoids both waste of raw materials and pollution of the working environment, while also ensuring high efficiency of the entire feeding process.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this embodiment. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this embodiment, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment according to the specific circumstances.

[0046] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0047] like Figure 1 and Figure 5As shown, a powder feeding device according to an embodiment of the present invention includes a feeding frame 100, a feeding bin 200, a feeding assembly, and a distributing pipe 300. The feeding bin 200 is disposed at the upper end of the feeding frame 100, and the top of the feeding bin 200 is provided with an inlet 210. The inner wall of the inlet 210 is provided with an inflatable and expandable sealing part 211. The feeding assembly is connected to the outlet end of the feeding bin 200 and is used to output the material in the feeding bin 200. The distributing pipe 300 is disposed on the feeding frame 100, the inlet end of the distributing pipe 300 is used to receive the material output by the feeding assembly, and the outlet end of the distributing pipe 300 is used to add the material into the electrolytic furnace 400.

[0048] The powder feeding device of this embodiment has an inflatable and expandable sealing part 211 ringed around the inner wall of the feed inlet 210. After the open end of the material bucket containing the proportioned and mixed material is inserted into the feed inlet 210, the sealing part 211 inflates and expands, filling and sealing the space between the outer side of the open end of the material bucket and the inner side of the feed inlet 210. This ensures that the material will not leak from the connection between the open end of the material bucket and the feed inlet 210 to the outside and generate dust when the material bucket is opened and the material is added to the feeding bin 200 by gravity. This avoids waste of raw materials and pollution of the working environment, and the entire feeding process is highly efficient.

[0049] It should be noted that the material in this embodiment refers to rare earth metal powder. Of course, in specific applications, it can also be common metal powder.

[0050] It should be noted that after the material in the material bucket is added into the feeding hopper 200 to complete the feeding, the sealing part 211 can be degassed, so that there is a gap between the outer side of the opening end of the material bucket and the inner side of the feed inlet 210, so that the material bucket can be pulled out from the feed inlet 210 of the feeding hopper 200.

[0051] like Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, a tilting hopper 510 is provided between the feeding assembly and the distributing pipe 300. The tilting hopper 510 is rotatably connected to the feeding frame 100. The tilting hopper 510 is driven to rotate by a rotary drive mechanism. The tilting hopper 510 has a first state where it tilts to pour material into the distributing pipe 300, and a second state where it is horizontally arranged and receives material output from the feeding assembly. By transitionally connecting the tilting hopper 510 between the feeding assembly and the distributing pipe 300, after the feeding assembly delivers a fixed amount of material into the tilting hopper 510 in the second state, the feeding assembly stops outputting material and drives the tilting hopper 510 to rotate, switching the tilting hopper 510 from the second state to the first state. This achieves precise single-pass addition of a fixed amount of material into the electrolysis furnace 400 through the distributing pipe 300, improving the weight accuracy of the material added to the electrolysis furnace 400 in a single operation and ensuring the quality of electrolysis.

[0052] It should be noted that when the tilting hopper 510 is in the second state, it stops pouring material into the distribution pipe 300.

[0053] like Figure 3 and Figure 5 As shown, specifically, the feeding bin 200 is cone-shaped, with the upper part of the feeding bin 200 being the main part, and the inlet 210 being located at the main part. The outer wall of the main part is provided with four mounting ears 250 spaced apart along the circumference. The mounting ears 250 are connected to the feeding frame 100 by bolts so that the feeding bin 200 and the feeding frame 100 can be disassembled and assembled, thereby facilitating maintenance.

[0054] In some embodiments, a rotary mounting base 520 is provided between the tilting hopper 510 and the feeding frame 100. The tilting hopper 510 is rotatably connected to the top of the rotary mounting base 520 via a mounting shaft 530. A weighing sensor is provided at the top of the rotary mounting base 520. The weighing sensor, the rotary drive mechanism, and the feeding assembly are all connected to a controller. In the second state, the tilting hopper 510 presses against the weighing sensor. During the process of feeding material into the tilting hopper 510, the weighing sensor can detect the weight of the material in the tilting hopper 510 in real time and transmit the measured weight value to the controller. When the measured weight value is the same as the set weight value, the controller transmits a control signal to the rotary drive mechanism and the feeding component, so that after the feeding component stops outputting material, it drives the tilting hopper 510 to rotate, causing the tilting hopper 510 to switch from the second state to the first state. This achieves precise feeding of a fixed amount of material into the electrolysis furnace 400 in a single pass through the distribution pipe 300, improving the weight accuracy of the material added into the electrolysis furnace 400 in a single pass and ensuring the quality of electrolysis.

[0055] To further improve the accuracy of the weighing sensor in weighing materials located in the tilting hopper 510, such as Figure 3 and Figure 6 As shown, more specifically, the mounting shaft 530 is located on the side of the center of the tilting hopper 510 relatively close to the distribution pipe 300, so that the tilting hopper 510 in the second state fully presses against the weighing sensor.

[0056] like Figure 7 As shown, specifically, the rotary drive mechanism includes a rotary cylinder 610 disposed on the feeding frame 100. The output end of the rotary cylinder 610 is provided with a drive plate 620. The mounting shaft 530 is provided with two support legs 531 at one end facing the rotary cylinder 610. The two support legs 531 are spaced apart, and the drive plate 620 is embedded between the two support legs 531. When the tilting hopper 510 is in the second state, the drive plate 620 is disengaged from the support legs 531. Two support legs 531 are spaced apart on the end face of the mounting shaft 530 facing the rotary cylinder 610. The drive plate 620 is embedded between the two support legs 531. Because the height of the drive plate 620 is greater than the distance between the two support legs 531, and the thickness of the drive plate 620 is less than the distance between the two support legs 531, after switching the tilting hopper 510 to the second state, the drive plate 620 can be rotated to a position where it does not contact the two support legs 531. At this time, the tilting hopper 510 is basically supported by the rotary mounting base 520, ensuring that the load cell can accurately detect the weight of the tilting hopper 510 and the weight of the material inside the tilting hopper 510. When it is necessary to switch the tilting hopper 510 from the second state to the first state, the rotary cylinder 610 first drives the drive plate 620 to rotate a short idle stroke until the drive plate 620 abuts against the two support legs 531, and then rotates to switch the tilting hopper 510 from the second state to the first state.

[0057] like Figure 3 and Figure 5As shown, in some embodiments, the tilting hopper 510 is disposed obliquely below the discharge end of the feeding bin 200; the powder feeding device further includes a first conveying component 710 disposed on the feeding frame 100, the vertical projection of the discharge end of the feeding component falls within the range of the first conveying component 710, and the vertical projection of the discharge end of the first conveying component 710 falls within the range of the tilting hopper 510; a first linear vibrator 720 is disposed between the bottom end of the first conveying component 710 and the feeding frame 100. Because the tilting hopper 510 needs to rotate to automatically switch between the first and second states, a first conveying component 710 is provided between the discharge end of the feeding assembly and the tilting hopper 510. A gap exists between the first conveying component 710 and the tilting hopper 510 in the vertical direction. This gap allows the portion of the tilting hopper 510 relatively close to the first conveying component 710 to pass through during tilting without contacting or interfering with the first conveying component 710. This allows material to be conveyed into the tilting hopper 510 without interfering with its rotational movement. Simultaneously, a first linear vibrator 720 applies vibration excitation to the material within the first conveying component 710, loosening the material and preventing clumping while conveying it into the tilting hopper 510.

[0058] Specifically, the feeding frame 100 is provided with a mounting platform 110, and the first linear vibrator 720 is mounted on the mounting platform 110.

[0059] like Figure 3 and Figure 5 As shown, specifically, the feeding assembly includes a twin-helix conveyor 220. One end of the twin-helix conveyor 220 is equipped with a drive motor 230, and the other end is equipped with a discharge pipe 240. The discharge pipe 240 is connected to the discharge end of the feeding hopper 200, and is used to convey materials into the distribution pipe 300. The twin-helix conveying capacity of the twin-helix conveyor 220 is more controllable, and the conveyed materials are less prone to clumping, which is beneficial to improving the subsequent weighing accuracy.

[0060] More specifically, the discharge pipe 240 has an opening at its upper vertical end, which is connected to the discharge end of the feeding bin 200.

[0061] like Figure 1 , Figure 2 and Figure 5As shown, in some embodiments, the lower end of the distribution pipe 300 is connected to a first discharge section 310 and a second discharge section 320. The first discharge section 310 and the second discharge section 320 are arranged opposite each other in the horizontal direction. The first discharge section 310 and the second discharge section 320 respectively add materials to the corresponding electrolytic furnace 400. A distribution hopper 330 is rotatably arranged in the feed end of the distribution pipe 300 through a rotating rod. The distribution hopper 330 has a third state of tilting and pouring materials into the first discharge section 310, a fourth state of horizontally receiving materials output from the tilting hopper 510, and a fifth state of tilting and pouring materials into the second discharge section 320. One end of the rotating rod extends outside the distribution pipe 300 and is connected to a drive assembly. By connecting a first discharge section 310 and a second discharge section 320 to the lower end of the distribution pipe 300, and rotatably assembling a distribution hopper 330 within the feed end of the distribution pipe 300, the distribution hopper 330 alternately conveys a fixed quantity of material to the first discharge section 310 and the second discharge section 320. This allows for the alternating delivery of a fixed quantity of material to two electrolytic furnaces 400 using only one powder feeding device, improving equipment utilization. Furthermore, by connecting a drive assembly to one end of the rotating rod extending outside the distribution pipe 300, the distribution hopper 330 can be automatically switched between three, four, and five states, achieving a high degree of automation.

[0062] Specifically, the drive assembly includes a gear 810, a rack 820, and an electric cylinder 830. The gear 810 is coaxially connected to the rotating rod. The rack 820 is slidably disposed on the feeding frame 100 and meshes with the gear 810. The electric cylinder 830 is disposed on the feeding frame 100, and the telescopic end of the electric cylinder 830 is connected to the rack 820. This allows the gear 810 to rotate forward or backward simply by controlling the electric cylinder 830 to extend or retract the rack 820, thereby automatically switching the material distribution hopper 330 between the third, fourth, and fifth states.

[0063] In practical applications, the electric cylinder 830 can also be replaced by linear motors, cylinders, or other linear drive components, as long as it drives the rack 820 to move back and forth in a linear manner.

[0064] Specifically, the first discharge section 310, the second discharge section 320, and the distribution pipe 300 are integrally formed and arranged in an inverted Y shape.

[0065] It should be understood that the horizontal direction refers to any direction within the horizontal plane. For ease of description, this embodiment uses... Figure 2 The horizontal direction in the text is described as a horizontal direction, but should not be interpreted as a specific limitation on the horizontal direction.

[0066] like Figure 5 and Figure 6As shown, specifically, a sensor mounting base 840 is provided on one side of the rack 820 on the feeding frame 100. A first proximity switch 850, a second proximity switch 860, and a third proximity switch 870 are sequentially spaced along the length of the rack 820 on the sensor mounting base 840. The first proximity switch 850, the second proximity switch 860, the third proximity switch 870, and the electric cylinder 830 are all connected to a controller. When the distributing hopper 330 is in the third state, the rack 820 triggers the first proximity switch 850. When the distributing hopper 330 is in the fourth state, the rack 820 triggers the second proximity switch 860. When the distributing hopper 330 is in the fifth state, the rack 820 triggers the third proximity switch 870. By setting a proximity switch for each of the material hoppers 330 in different states, and connecting each proximity switch to a controller, when the rack 820 moves to trigger one of the proximity switches (first proximity switch 850, second proximity switch 860, or third proximity switch 870), a signal is fed back to the controller. The controller then controls the electric cylinder 830 to stop, thereby achieving precise control of the extension and retraction stroke of the electric cylinder 830, and thus achieving precise control of the material hopper 330 switching to the third, fourth, or fifth state.

[0067] like Figure 1 and Figure 2 As shown, specifically, the discharge ends of the first discharge section 310 and the second discharge section 320 are both connected to a second conveying component 910. The vertical projection of the discharge end of the second conveying component 910 falls within the range of the corresponding electrolytic furnace 400. A second linear vibrator 920 is provided at the bottom of the second conveying component 910. A connecting platform 930 is provided at the end of the second linear vibrator 920 away from the second conveying component 910. Both the connecting platform 930 and the feeding frame 100 are suitable for installation on the ground. Because the temperature during electrolysis in the electrolytic furnace 400 is at least 1000℃, if the discharge ends of the first discharge section 310 and the second discharge section 320 are directly above the electrolytic furnace 400, they are prone to wear and tear and are inconvenient to maintain. Therefore, in this embodiment, a second conveying component 910 is used as a transitional connection between the discharge ends of the first discharge section 310 and the second discharge section 320 and the corresponding electrolytic furnace 400. The second conveying component 910 is separately arranged from the first discharge section 310 and the second discharge section 320. When the part of the second conveying component 910 near the electrolytic furnace 400 is worn or deformed, the worn part can be cut off and reused, which is convenient for short-term maintenance. Replacement is only required when the total length is insufficient. At the same time, the second linear vibrator 920 applies vibration excitation to the material located in the second conveying component 910, so that the material is loosened while being conveyed to the corresponding electrolytic furnace 400 to prevent the material from clumping together.

[0068] like Figures 2 to 4 As shown, specifically, two equilateral angle steels 940 are provided directly below each of the second linear vibrators 920. The equilateral angle steels 940 are located on the connecting platform 930, and the arrangement direction of the equilateral angle steels 940 is parallel to the arrangement direction of the second conveying component 910. A support frame 950 is provided at the bottom end of the second linear vibrator 920, and the bottom end of the support frame 950 is slidably mounted on the equilateral angle steels 940 via a support V-shaped wheel 951. This allows the two second conveyor components 910 to be adjusted to move closer to each other or further apart. Firstly, it allows for flexible manual adjustment of the relative distance between the discharge end of the second conveyor component 910 and the electrolytic furnace 400, facilitating the optimal feeding port adjustment. Secondly, it allows the two second conveyor components 910 to be moved closer to each other, ensuring that the discharge end of the second conveyor component 910 is not directly above the electrolytic furnace 400, thus facilitating the replacement of the furnace platform or anode plates of the electrolytic furnace 400. Thirdly, when the portion of the second conveyor component 910 near the electrolytic furnace 400 becomes worn or deformed, the worn portion can be removed, and then the two second conveyor components 910 can be adjusted to move further apart, ensuring that the discharge end of the second conveyor component 910 is in the optimal feeding position while allowing continued use after removing the worn portion.

[0069] Specifically, two support V-shaped wheels 951 are provided between the bottom end of the support frame 950 and each equilateral angle steel 940.

[0070] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the appended invention.
