[0002] Molten pool smelting technology is a smelting method commonly used in the field of metallurgy. It heats the metal material to above its melting point, converts it into liquid, and then smelts and refines it in a molten pool. This technology is widely used in metal smelting, alloy preparation, and scrap metal recycling, greatly improving the efficiency and quality of metal smelting. The antimony smelting process mainly includes pyrometallurgical and hydrometallurgical processes. The pyrometallurgical process obtains antimony oxide by roasting and smelting sulfide ore, and produces crude antimony by reduction smelting, which is then purified by electrolytic refining.

[0003] A Chinese patent with publication number CN103924100A discloses a method and device for producing crude antimony by smelting antimony oxide-containing materials in a molten pool, including an oxygen-enriched side-blown reduction molten pool smelting furnace, a waste heat boiler, an electrostatic precipitator, and a bag dust removal device; the flux iron ore and lime mainly contain silicate components; the reducing agent and fuel mainly contain fixed carbon or volatiles.

[0004] In the above technical scheme, although it can reduce energy consumption, simplify operation and improve direct recovery rate, due to the relatively small smelting capacity area of ​​the molten pool, the solid material flux and auxiliary agent added in the process need to be smoothed, and not smoothing is not conducive to improving the direct recovery rate. For this reason, the present invention provides a method and device for producing crude antimony by smelting antimony oxide-containing material in a molten pool to solve the above problems.

During the process, a certain amount of solid material flux and additives need to be added to ensure the stability of the molten pool and the purity of the metal. During the roasting process, the fluidity inside the molten pool furnace is relatively thick or relatively dilute, which will affect the production efficiency of the crude antimony.

[0037] like Figure 1 to Figure 2 As shown, when working, before producing crude antimony, oxygen is usually blown into the molten pool furnace 1 to heat the antimony-containing material to a molten state, and a proper amount of oxidant is added to the molten pool furnace 1 for oxidation reaction, and then the sulfide ore is roasted / smelted to obtain antimony oxide, and the crude antimony is produced by reduction smelting, and electrolytic refining and purification are performed. During the process, a certain amount of solid material flux and additives are also required to ensure the stability of the molten pool and the purity of the metal. During the roasting process, the fluidity inside the molten pool furnace 1 is relatively concentrated or relatively diluted, which will affect the production efficiency of crude antimony. Therefore, when the fluidity needs to be changed, the present invention is used. In the embodiment, the servo motor is started, and the rotating rod 53 is energized to rotate counterclockwise. The rotating rod 53 rotates counterclockwise and moves upward from the telescopic cylinder 5. When the rotating rod 53 moves upward, it gradually links and affects the auxiliary components and the flow components. The auxiliary components gradually work. Through the setting of the auxiliary components, the auxiliary components are prompted to flip the solid materials up or down, which facilitates the change of the position of the solid materials in the molten pool furnace 1. In this process, through the setting of the flow components, the smelting temperature of the fluidity in the molten pool furnace 1 is changed, so that the material will not be too concentrated or too thin, thereby ensuring the efficiency of the output of crude antimony.

[0038] The auxiliary component includes a spring 2 52 fixedly mounted on the inner bottom wall of the telescopic cylinder 5, a rotating rod 53 is rotatably mounted inside the telescopic cylinder 5, the bottom of the rotating rod 53 is rotatably arranged with the top of the spring 2 52, a matching texture is arranged between the rotating rod 53 and the telescopic cylinder 5, the rotating rod 53 is rotatably mounted on the top of the telescopic cylinder 5, an inclined plate 54 is rotatably connected to the top of the rotating rod 53, an insert disk 55 is fixedly connected to the lower part of the other end of the inclined plate 54 away from the rotating rod 53, a sorting head 56 is inserted into the center of the bottom end of the insert disk 55, a fixing piece 57 is sleeved on the outer side of the insert disk 55, the telescopic cylinder 5 is connected to the insert disk 55 through the fixing piece 57, the fixing piece 57 is made of stainless steel, and the fixing piece 57 is fixedly connected to the telescopic cylinder 5.

[0039] like Figures 2 to 3As shown, during operation, due to the high temperature in the molten pool furnace 1, when solid materials are added for smelting, the bottom of the solid materials is melted first, and the top of the solid materials cannot be melted for a short time. The bottom needs to be melted into liquid before the solid materials on the top can be melted. When encountering special circumstances, it is inconvenient to turn the top when it needs to be melted first. By using the embodiment of the present invention, the rotating rod 53 is energized and gradually moves upward or downward, and the rotating rod 53 is pulled out from the telescopic cylinder 5. If the rotating rod 53 squeezes the inclined plate 54 upward, the inclined plate 54 moves upward, and the insert plate 55 moves accordingly, and the sorting head 56 gradually moves upward. The sorting head 56 is placed on the molten pool furnace 1 by default, and the solid materials in the molten pool furnace 1 are moved upward by the sorting head 56. The sorting head 56 promotes smelting by changing the position of the solid materials, and at the same time facilitates the turning and sorting of the materials in the molten pool furnace 1, thereby improving the general performance of use.

[0040] A displacement assembly is fixedly connected to the inner wall of the fixed plate 2, and the displacement assembly includes a processor 22 installed inside the molten pool furnace 1. The front end face of the molten pool furnace 1 is slidably connected to the processor 22, and the rear end face of the processor 22 is fixedly connected to a central axis 23. The central axis 23 penetrates the molten pool furnace 1, and an output end of the central axis 23 is fixedly connected to a connecting plate 24. A connecting bar 25 is elastically connected to the side of the connecting plate 24 away from the central axis 23, and the angle between the connecting bar 25 and the connecting plate 24 is ninety degrees. A sensor 26 is arranged at the output end of the connecting bar 25, and a spring 20 is elastically connected inside the connecting bar 25, and the spring 20 is located inside the connecting bar 25.

[0041] like Figures 3 to 5 As shown, in the process of adding a certain amount of solid material flux and auxiliary agent, the uneven solid material needs to be smoothed. During operation, by using the embodiment of the present invention, when the rotating rod 53 moves upward, the rotating rod 53 is linked with the spring 2 52 to operate, and the spring 2 52 moves upward. The spring 2 52 pulls the spring 1 20, and the spring 1 20 drags the connecting bar 25 to cause a lateral displacement. The connecting bar 25 is linked with the connecting plate 24 to operate, and the connecting plate 24 is displaced in the direction close to the telescopic cylinder 5. The connecting plate 24 is linked with the central axis 23 to move. When the central axis 23 moves, it drives the screen bar 6 to move synchronously. When the screen bar 6 moves, it gradually swings. During the movement, the screen bar 6 will contact the top of the solid material, so that the uneven material is gradually smoothed and the fluidity of the molten pool furnace 1 is changed. The sensor 26 feeds back the sensed temperature to the processor 22.

[0042] The flow component includes two plate parts 61 installed on the side walls of the screen bar 6. The sides of the two plate parts 61 are fixed with arcs 62.

Multiple plug-ins 64 are inserted into the inner wall of the thin layer 63.

[0043] like Figures 4 to 5As shown, during operation, in the process of changing the fluidity of the molten pool furnace 1, boiling is likely to occur due to the high temperature in the molten pool furnace 1. When boiling, the splashing of the solution will corrode the surrounding area, posing certain safety hazards and affecting the production of crude antimony. When the screen bars 6 are displaced, the screen bars 6 push the plate body 61 to move, and the plate body 61 drives the arc body 62 to displace synchronously. The arc body 62 acts on the thin layer 63. When the thin layer 63 is displaced, it gradually covers the top of the molten pool furnace 1. The thin layer 63 and the arc body 62 form a protection for the bottom to prevent the boiling of the molten solution and splashing to affect safety. The plug-in 64 facilitates observation and turning over of the middle part, thereby enabling the equipment to quickly change the fluidity while ensuring that the process of producing crude antimony is safer.

[0044] A height adjustment component is provided at the top of the arc body 62, and the height adjustment component includes a special bar 622 installed on the side of the insert plate 55, and a sieve plate 623 is fixedly connected to the top of the special bar 622. A rotating shaft 624 is rotatably installed at the bottom of the molten pool furnace 1, and a layer plate 625 is sleeved on the outer surface of the rotating shaft 624. The arc body 62 is located on the layer plate 625, and the layer plate 625 is located at the bottom of the molten pool furnace 1. A plurality of vertical plates 626 are fixedly connected to the bottom end of the layer plate 625, and the vertical plates 626 are embedded and installed at the bottom of the layer plate 625. The bottom sides of the plurality of vertical plates 626 are fixedly connected to an italic body 627, and the italic body 627 is made of stainless steel.

[0045] like Figures 6 to 8 As shown, during operation, in the process of protecting the molten solution, there will be a situation where the arc body 62 has a low coverage area, causing the solution to still splash to various parts during smelting, which is inconvenient to adjust and has certain limitations. The upward movement of the rotating rod 53 will push the inclined plate 54, and the inclined plate 54 will move upward, and the inclined plate 54 will move in conjunction with the insert plate 55, and the insert plate 55 will drive the sieve plate 623 to move upward, and the sieve plate 623 will move and drag the special supply strip 622 to move, and the special supply strip 622 will pull the arc body 62 to move upward, and the upward displacement of the arc body 62 will increase the coverage distance, thereby enabling the equipment to have the purpose of quickly adjusting the height and achieving the purpose of improving versatility;

[0046] After the crude antimony is produced and prepared, when the molten pool furnace 1 needs to be cleaned, water is directly poured into it. When the water flow impacts, it gradually contacts the layer plate 625, and the layer plate 625 is affected and swings. The layer plate 625 rotates with the shaft 624 as the shaft. The layer plate 625 pushes the vertical plate 626 and the oblique body 627 to move. The oblique body 627 gradually cleans the inside of the molten pool furnace 1, thereby ensuring the cleanliness of the equipment and improving the convenience of cleaning.

[0047] A method for producing crude antimony by smelting antimony oxide-containing materials in a molten pool, comprising the following steps:

[0048] S1: Before the production of crude antimony, the sulfide ore is roasted / smelted to obtain antimony oxide, and the crude antimony is produced by reduction smelting. A certain amount of solid material flux and additives are added, and the rotating rod 53 is energized and moved upward to gradually link the auxiliary components and the flow components to work;

[0049] S2: After the sulfide ore is roasted, a smelting solution is generated. When the added solid materials need to be turned over and sorted, the rotating rod 53 presses the inclined plate 54 upward, and the sorting head 56 moves accordingly, gradually moving upward, and the sorting head 56 moves to turn over and sort the solid materials in the molten pool furnace 1;

[0050] S3: During the production process of molten pool smelting, there will be a situation where the fluidity in the molten pool furnace 1 is poor, which is not conducive to the subsequent metallurgical reaction of crude antimony. The spring 2 52 moves upward, and the spring 2 52 cooperates with the spring 1 20, the connecting bar 25, and the connecting plate 24 to operate, so that the screen bar 6 gradually swings when it moves, and the displacement of the screen bar 6 changes the fluidity of the molten pool furnace 1;

[0051] S4: When the screen bar 6 moves, the screen bar 6 pushes the plate member 61 to move, and the plate member 61 drives the arc member 62 to move synchronously. The arc member 62 acts on the thin layer 63. When the thin layer 63 moves, it gradually covers the top of the molten pool furnace 1. The thin layer 63 and the arc member 62 form a protection for the bottom to prevent the boiling of the molten solution and splashing to affect safety.

[0052] S5: In the process of protecting the molten solution, there may be a situation where the arc body 62 has a low coverage area, causing the solution to still splash to various parts during smelting. The inclined plate 54 is linked to the insert plate 55 to move, and the insert plate 55 drives the special supply strip 622 to move through the sieve plate 623. The arc body 62 is affected and moves upward to increase the coverage distance;

[0053] S6: When the molten pool furnace 1 needs to be cleaned, water is directly poured into it. The water flow gradually contacts the layer plate 625 when impacting. The layer plate 625 is affected and swings. The layer plate 625 rotates around the shaft 624. The layer plate 625 pushes the vertical plate 626 and the inclined body 627 to move.

[0054] Working principle: When working, before producing crude antimony, start the servo motor, and the rotating rod 53 rotates counterclockwise when powered on. The rotating rod 53 rotates counterclockwise and moves upward from the telescopic cylinder 5. When the rotating rod 53 moves upward, it gradually links to squeeze the inclined plate 54. The inclined plate 54 moves upward, and the insert plate 55 moves accordingly. The sorting head 56 gradually moves upward. The sorting head 56 is placed on the molten pool furnace 1 by default. The solid materials in the molten pool furnace 1 are moved upward by the sorting head 56. The sorting head 56 promotes smelting by changing the position of the solid materials, and at the same time facilitates the turning and sorting of the materials in the molten pool furnace 1, thereby improving the general performance of use;

[0055] In the process of producing crude antimony, the rotating rod 53 is linked with the spring 2 52 to operate, the spring 2 52 moves upward, the spring 2 52 pulls the spring 1 20, and the spring 1 20 drags the connecting bar 25 to move horizontally, the connecting bar 25 is linked with the connecting plate 24 to operate, the connecting plate 24 moves toward the direction close to the telescopic cylinder 5, the connecting plate 24 is linked with the central axis 23 to move, and the displacement of the central axis 23 drives the screen bars 6 to move synchronously, and the screen bars 6 gradually swing when they are displaced, and the molten solution in the bottom molten pool furnace 1 is blown when the screen bars 6 swing. Under the action of the blowing force, the displacement of the screen bars 6 changes the fluidity of the molten pool furnace 1, and changes the smelting temperature of the fluidity in the molten pool furnace 1, so that the material will not be too concentrated or too thin, thereby ensuring the efficiency of the output of crude antimony.
