Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for nonferrous metal smelting, in particular to a feeding device for nonferrous metal smelting. Background Art

[0002] Non-ferrous metal smelting primarily refers to the production process of producing non-ferrous metals or their compounds by separating associated elements from ores, concentrates, secondary resources, or other materials. Non-ferrous metal smelting primarily includes: 1. Full pyrometallurgical processes: The entire process of extracting metals from related materials is carried out at temperatures exceeding hundreds of degrees Celsius, or processes in which pyrometallurgical processes dominate the overall process. The production of heavy non-ferrous metals such as copper, nickel, lead, zinc, tin, and mercury is primarily based on a full pyrometallurgical process, from sintering and smelting to refining to finished products, all carried out at high temperatures; 2. Full hydrometallurgical processes: The entire process of extracting metals from related materials, or processes in which hydrometallurgical processes dominate the overall process. Examples include roasting of zinc sulfide concentrate, leaching of the roasted ore (see leaching), purification of the leachate, and electrolysis of the zinc-containing solution, but the primary processes are leaching, purification, and electrolysis. Extracting gold and silver from gold and silver ore is the most widely used example of a fully hydrometallurgical process. 3. Combined hydrometallurgical-pyrometallurgical process: Both hydrometallurgical and pyrometallurgical processes account for a significant portion of the production process and are the most widely used in modern nonferrous metal production. In this combined process, pyrometallurgical and hydrometallurgical processes are closely linked and complement each other. For example, the Bayer process produces alumina from bauxite, which is then electrolyzed through molten salts to produce metallic aluminum. Almost all rare metals are first produced from the corresponding raw materials using hydrometallurgical methods to produce pure compounds, and then from these pure compounds using pyrometallurgical methods to produce the metal. This advantageously allows for the optimal selection of metals by leveraging the characteristics of the raw minerals and leveraging established technologies for appropriate coordination.

[0003] During the full pyrometallurgical smelting process of heavy nonferrous metals, solvents need to be regularly added to the furnace to adjust the chemical properties of the slag and promote the removal of impurities. For example, in pyrometallurgical copper smelting, solvents (limestone, quartz, etc.) need to be added to the furnace. In the prior art, when adding solvents to the furnace, fine particles or powders are usually added. When undispersed powders or particles are directly added to the furnace, the outer layer of solvent reacts with the high-temperature solution to form a protective layer. The solvent in the inner layer of the particles or the solvent inside the powder cannot further react with the solution. At the same time, the solvent powder is not dispersed, which will cause the viscosity of the slag to increase, affecting the fluidity of the slag, which may cause agglomeration, affecting the smelting efficiency and the quality of the final product. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a feeding device for non-ferrous metal smelting to solve the problem in the prior art that powder solvent is difficult to disperse when adding powder solvent during non-ferrous metal smelting.

[0012] Furthermore, the feeding rack includes a connecting plate and a supporting plate, the connecting plate is connected to the output end of the conveying component, and the lower side of the connecting plate is connected to the supporting plate through a connecting column.

[0013] Furthermore, the temporary storage box is installed on the lower side of the support plate, the feeding pipe is communicated with the temporary storage box, and the upper end of the feeding pipe is in an open funnel shape.

[0014] Furthermore, the powder sprinkling assembly includes a powder sprinkling plate, the feeding hole is located at the bottom of the powder sprinkling plate, the outer walls on both sides of the powder sprinkling plate are connected to the support plate through connecting rods, and a universal joint is also installed in the middle of the connecting rods.

[0015] Furthermore, the outer wall of the powder sprinkling plate is also provided with a splash-proof cover.

[0016] Furthermore, the scraping assembly includes a scraping plate and a power motor. The power motor is installed in the temporary storage box, and a sealing cover is installed on the outside of the power motor. The output end of the power motor is connected to the scraping plate through a rotating shaft. The scraping plate is located in the powder spreading assembly.

[0017] Furthermore, a toggle assembly is installed in the powder spreading plate.

[0018] Furthermore, the toggle assembly includes a toggle plate and a rotating column, both ends of the rotating column are installed on the inner wall of the powdering plate through fixed columns, the rotating column is connected to the toggle plate, and a return spring is also installed between the toggle plate and the inner wall of the powdering plate, and the scraper plate rotates so that its toggle plate abuts against the scraper plate.

The powder then enters the powder spreading plate from the feeding pipe. The power motor drives the scraper plate to rotate, spreading the powder on the powder spreading plate and discharging it from the feeding port into the furnace. This ensures that the powder is more evenly spread on the powder spreading plate and enters the solution surface from the feeding port under the continuous scraping of the scraper plate, ensuring that the powder solvent is evenly spread on the solution surface, thereby increasing the reaction rate and reducing the formation of agglomeration and slag.

[0022] 2. During the continuous rotation of the scraper plate, the outer edge will intermittently abut and collide with the paddle plate, which pushes the spreading plate to swing slightly, so that the powder is more evenly sifted on the surface of the solution;

[0023] 3. The splash-proof cover reduces the splashing of solution when adding powder. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figure 1-4 The utility model provides a technical solution: a feeding device for nonferrous metal smelting, comprising

[0036] Conveying component 1 is used to convey the powder to a specified height so that the powder can be evenly spread on the surface of the high-temperature furnace solution.

[0037] A feeding rack 2 is installed at the end of the conveying assembly 1, and can also be installed at the upper end of the high-temperature furnace. An automatic metering device 3 is installed in the feeding rack 2. The automatic metering device 3 is located at the output end of the conveying assembly 1. The automatic metering device 3 is electrically connected to a control device (not shown in the figure) for accurately controlling the weight of the powder fed into the furnace at a single time;

[0038] The temporary storage box 4 is installed on the feeding frame 2 and is located at the output end of the automatic metering device 3. It is mainly used to receive the powder delivered from the conveying component 1. The temporary storage box 4 is connected to the feeding pipe 5;

[0039] A powder spreading assembly 6 is mounted on the lower side of the feeding frame 2 and is located at the output end of the feeding pipe 5. The powder spreading assembly 6 has a feeding hole 7.

[0040] The scraping assembly 8 is installed on the feeding frame 2 and the scraping end of the scraping assembly 8 is located in the powder spreading assembly 6.

[0041] In this embodiment, the automatic metering device 3 can adopt a bucketless spiral scale of model HHD-F50W. The conveying component 1 conveys the solvent powder to the temporary storage box 4. The control device (not shown in the figure) obtains the weighing data of the automatic metering device 3. After reaching the set data, the conveying component 1 is controlled to stop automatically. The powder is transported to the powder spreading component 6 along the feeding pipe 5 under the action of gravity. The scraping end of the scraping component 8 rotates in the powder spreading component 6 to evenly spread the powder and evenly spread it to the surface of the solution along the feeding hole 7, reducing the solvent agglomeration and increasing the reaction rate between the solution and the solvent.

[0042] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the feeding frame 2 includes a connecting plate 9 and a support plate 10, the connecting plate 9 is connected to the output end of the conveying component 1, and the lower side of the connecting plate 9 is connected to the support plate 10 through a connecting column.

[0043] In this embodiment, the connecting plate 9 and the support plate 10 are both made of high-temperature resistant metal plates. The connecting plate 9 and the support plate 10 are connected by multiple connecting columns, so that there is a gap between the connecting plate 9 and the support plate 10, which is beneficial for the operator to observe from the gap whether the powder is delivered to the automatic metering device 3 when conveying the powder.

[0044] The temporary storage box 4 is installed on the lower side of the support plate 10. The feeding pipe 5 is connected to the temporary storage box 4, and the upper end of the feeding pipe 5 is in an open funnel shape.

[0045] In this embodiment, the upper end of the feeding pipe 5 is open, which is conducive to the rapid transportation of powder into the feeding pipe 5 and reduces the powder remaining in the temporary storage box.

[0046] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in another embodiment, the powder sprinkling assembly 6 includes a powder sprinkling plate 11, the feeding hole 7 is located at the bottom of the powder sprinkling plate 11, the outer walls on both sides of the powder sprinkling plate 11 are connected to the support plate 10 through a connecting rod 12, a universal joint 13 is also installed in the middle of the connecting rod 12, and a splash-proof cover 14 is also installed on the outer wall of the powder sprinkling plate 11.

[0047] In this embodiment, after the scraping assembly 8 evenly spreads the powder on the bottom of the powdering plate 11, the powder falls from the feeding hole 7 to the surface of the solution. The two sides of the powdering plate 11 are connected to the support plate 10 through the connecting rod 12, and a universal coupling 13 is also installed in the middle of the connecting rod 12, which is conducive to the slight swing of the powdering plate 11, so that the powdering plate 11 is similar to a vibrating screen, and the powder is sieved on the surface of the solution. In order to avoid splashing when the powder enters the solution and affect the personal safety of the operator, a splash-proof cover 14 is also installed on the outer wall of the powdering plate 11.

[0048] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the scraping assembly 8 includes a scraping plate 15 and a power motor 16. The power motor 16 is installed in the temporary storage box 4, and a sealing cover is installed on the outside of the power motor 16. The output end of the power motor 16 is connected to the scraping plate 15 through a rotating shaft, and the scraping plate 15 is located in the powder spreading assembly 6.

[0049] In this embodiment, the diameter of the scraper plate 15 is smaller than the diameter of the cavity in the temporary storage box 4. The power motor 16 can adopt a model YC100L1-2 asynchronous motor and is electrically connected to a control device. The control device can adopt a model BS62LV256 integrated control circuit board. The upper end of the sealing cover is spherical, which reduces the accumulation of powder on the sealing cover. The sealing cover reduces the powder from entering the power motor 16, thereby extending the practical life of the power motor 16.

[0050] like Figure 1 、 Figure 3 and Figure 4 As shown, in the embodiment, a toggle assembly 17 is also installed in the powdering disc 11. Specifically, the toggle assembly 17 includes a toggle piece 18 and a rotating column 19. Both ends of the rotating column 19 are installed on the inner wall of the powdering disc 11 through fixed columns. The rotating column 19 is connected to the toggle piece 18, and a return spring 20 is also installed between the toggle piece 18 and the inner wall of the powdering disc 11. The scraper plate 15 rotates so that its toggle piece 18 abuts against the scraper plate 15.

[0051] In this embodiment, one end of the toggle piece 18 is fixedly connected to the rotating column 19, so that the toggle piece 18 and the rotating column 19 can rotate along the fixed column. During the rotation of the scraper plate 15, it will abut against the toggle piece 18, thereby compressing the reset spring 20. When the toggle piece 18 and the scraper plate 15 are out of contact, the powder spreading plate 11 will reciprocate under the action of the reset spring 20, so that the powder spreading plate 11 is similar to a sieve plate, and the powder is evenly sifted onto the surface of the solution.

[0052] The conveying assembly 1 includes a conveying hopper 21 and a screw conveying assembly 22 . The input end of the screw conveying assembly 22 is located at the bottom of the conveying hopper 21 . A filter is also installed in the conveying hopper 21 .

[0053] In this embodiment, the crushed powder is conveyed into the conveying hopper 21, the filter screen will filter out large particles of impurities, and then the spiral conveying assembly 22 conveys the powder to the automatic metering device 3 for weighing and metering.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
