Technical Field

[0001] The invention belongs to the technical field of smelting, and in particular relates to a method and a device for producing crude antimony by smelting antimony oxide-containing materials in a molten pool. Background Art

[0002] Molten pool smelting technology is a smelting method commonly used in the metallurgical field. By heating the metal material to above its melting point, it is converted into liquid and smelted and refined in the 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. Among them, 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 through reduction smelting, which is then purified by electrolytic refining.

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

[0004] In the above technical solution, 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. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the device for producing crude antimony by smelting antimony oxide-containing materials in a molten pool described in the present invention comprises a molten pool furnace, fixed plates are fixedly connected to both sides of the molten pool furnace, a placement plate is fixedly connected to the rear end face of the molten pool furnace, a mounting seat is fixedly connected to the top of the placement plate, a telescopic cylinder is provided on the top of the mounting seat, a rotating rod is threadedly connected to the top of the telescopic cylinder, a servo motor is provided in the mounting seat, the output end of the servo motor is connected to the rotating rod, an auxiliary component is provided on the top of the telescopic cylinder, the auxiliary component is used to turn over the solid material in the molten pool, two screen bars are fixedly connected to the inside of the molten pool furnace, a flow component is provided on the inner side of the two screen bars, and the flow component is used to change the fluidity in the molten pool furnace; during operation, before producing crude antimony, oxygen is usually blown into the molten pool furnace to heat the antimony-containing material to a molten state, and an appropriate amount of oxidant is added to the molten pool furnace for oxidation reaction, and then antimony oxide is obtained by roasting / smelting the sulfide ore, and The original smelting produces crude antimony, which is then electrolytically refined and purified. 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 diluted, which will affect the production efficiency of crude antimony. Therefore, when the fluidity needs to be changed, the embodiment of the present invention is used to start the servo motor, and the rotating rod is energized to rotate counterclockwise. The rotating rod rotates counterclockwise and moves upward from the telescopic cylinder. When the rotating rod moves upward, it gradually links and affects the auxiliary component and the flow component. The auxiliary component gradually works. Through the setting of the auxiliary component, the auxiliary component is prompted to flip the solid material up or down, which is convenient for changing the position of the solid material in the molten pool furnace. In this process, the smelting temperature of the fluidity in the molten pool furnace is changed through the setting of the flow component, so that the material will not be too thick or too thin, thereby ensuring the efficiency of the crude antimony output.

[0007] Furthermore, the auxiliary component includes a spring 2 fixedly mounted on the bottom wall of the telescopic cylinder, a rotating rod is rotatably mounted inside the telescopic cylinder, the bottom of the rotating rod is rotatably arranged with the top of the spring 2, and a matching texture is arranged between the rotating rod and the telescopic cylinder, the rotating rod is rotatably mounted on the top of the telescopic cylinder, the top of the rotating rod is rotatably connected to an inclined plate, an insert disk is fixedly connected to the bottom of the other end of the inclined plate away from the rotating rod, a sorting head is inserted into the center of the bottom end of the insert disk, a fixing piece is sleeved on the outside of the insert disk, the telescopic cylinder is connected to the insert disk through the fixing piece, the fixing piece is made of stainless steel, and the fixing piece is fixed to the telescopic cylinder; during operation, due to the high temperature in the molten pool furnace, when solid materials are added for smelting treatment, the bottom of the solid materials are melted first , there is a situation where the top of the solid material cannot be melted for a short time, and the bottom needs to be melted into liquid before the solid material on the top can be melted. When encountering special circumstances, it is inconvenient to turn over the top when it needs to be melted first. By using the embodiment of the present invention, the rotating rod is energized and gradually moves upward or downward. The rotating rod is pulled out from the inside of the telescopic cylinder. If the rotating rod squeezes the inclined plate upward, the inclined plate moves upward, and the insert plate moves accordingly, and the sorting head gradually moves upward. The sorting head is placed on the molten pool furnace by default, and the solid material in the molten pool furnace is moved upward by the sorting head. The sorting head promotes melting by changing the position of the solid material, and at the same time it is convenient to turn over and sort the material in the molten pool furnace, thereby improving the general performance of use.

[0008] Furthermore, a displacement assembly is fixedly connected to the inner wall of the fixed plate. The displacement assembly includes a processor installed inside the molten pool furnace. The front end of the molten pool furnace is slidably connected to the processor. The rear end of the processor is fixedly connected to the central axis. The spring drags the connecting bar to cause a lateral displacement. The connecting bar drives the connecting plate to operate. The connecting plate moves toward the direction of the telescopic cylinder. The central axis passes through the molten pool furnace. The output end of the central axis is fixedly connected to the connecting plate. The side of the connecting plate away from the central axis is elastically connected to the connecting bar.

[0009] Furthermore, the angle between the connecting rod and the connecting plate is ninety degrees, a sensor is provided at the output end of the connecting rod, and a spring 1 is elastically connected inside the connecting rod, and the spring 1 is located inside the connecting rod; by using the present invention, when the rotating rod moves upward, the rotating rod links the spring 2 to operate, the spring 2 moves upward, the spring 2 pulls the spring 1, and the spring 1 drags the connecting rod to cause a lateral displacement, the connecting rod links the connecting plate to operate, the connecting plate moves toward the direction close to the telescopic cylinder, the connecting plate links the central axis to move, and the central axis moves, and the screen bars are driven to move synchronously, and the screen bars gradually swing when they move, and the screen bars blow the molten solution in the bottom molten pool furnace when they swing. Under the action of the blowing force, the displacement of the screen bars changes the fluidity of the molten pool furnace, and the sensor feeds back the sensed temperature to the processor, and the processor transmits the sensed electrical signal to the program, and the temperature is adjusted to a suitable temperature through the driver program, so as to achieve the effect of regulating the fluidity of the molten solution and avoid the situation where one of the places has poor fluidity.

[0010] Furthermore, the flow component includes two plate parts installed on the side walls of the screen bars. The screen bars push the plate parts to move, and the plate parts drive the arc parts to displace synchronously. The arc parts act on the thin layer, and when the thin layer displaces, it gradually covers the top of the molten pool furnace. The thin layer and the arc parts form protection for the bottom. The arc parts are fixed to the sides of the two plate parts, and a thin layer is fixed between the two arc parts.

[0011] Furthermore, the thin layer is made of stainless steel, and grooves corresponding to the plug-ins are opened on the thin layer, and multiple plug-ins are inserted into the inner wall of the thin layer; during operation, in the process of changing the fluidity of the molten pool furnace, boiling is likely to occur due to the high temperature in the molten pool furnace, and the splashing of the solution during boiling will corrode the surrounding area, posing certain safety hazards and affecting the production of crude antimony. When the screen bars are displaced, the screen bars push the plate parts to move, and the plate parts drive the arc parts to displace synchronously, and the arc parts act on the thin layer. When the thin layer is displaced, it gradually covers the top of the molten pool furnace. The thin layer and the arc parts form a protection for the bottom to prevent the boiling of the molten solution and splashing to affect safety. The plug-in facilitates observation and turning of the middle part, thereby enabling the equipment to quickly change the fluidity while ensuring a safer process of producing crude antimony.

[0012] Furthermore, a height adjustment component is provided at the top of the arc body, and the height adjustment component includes a special bar installed on the side of the insert plate. The insert plate drives the sieve plate to move upward, and the displacement of the sieve plate drags the special bar to move. The sieve plate is fixedly connected to the top of the special bar, and a rotating shaft is rotatably installed at the bottom of the molten pool furnace, and a layer plate is sleeved on the outer surface of the rotating shaft.

[0013] Furthermore, the arc is located on the layer plate, the layer plate is located at the bottom of the molten pool furnace, the bottom end of the layer plate is fixed with multiple vertical plates, the vertical plates are embedded and installed on the bottom of the layer plate, and the bottom sides of the multiple vertical plates are fixed with italics, which are made of stainless steel; when working, in the process of protecting the molten solution, there will be a situation where the arc coverage is low, 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 will push the inclined plate, and the inclined plate will move upward, and the inclined plate will move in conjunction with the insert plate, and the insert plate will drive the sieve plate to move upward. The displacement of the sieve plate drags the special supply bar to move, and the special supply bar pulls the arc body to move upward. The upward displacement of the arc body increases the coverage distance, thereby enabling the equipment to quickly adjust the height and achieve the purpose of improving versatility; after the crude antimony is produced and prepared, when the molten pool furnace needs to be cleaned, it is directly flushed into the water. When the water flow impacts, it gradually contacts the layer plate, and the layer plate is affected and swings. The layer plate rotates with the shaft as the axis, and the layer plate pushes the vertical plate and the oblique body to move. The oblique body gradually cleans the inside of the molten pool furnace, ensuring the clean effect of the equipment and improving the convenience of cleaning.

[0014] A method for producing crude antimony by smelting antimony oxide-containing materials in a molten pool, comprising the following steps:

[0015] S1: Before producing crude antimony, sulfide ore is roasted / smelted to obtain antimony oxide, which is then reduced and smelted to produce crude antimony. A certain amount of solid material flux and additives are added, and when the rotating rod is energized and moves upward, the auxiliary components and the flow components are gradually linked to work;

[0016] S2: After the sulfide ore is roasted, a smelting solution is generated. When the added solid materials need to be turned and sorted, the rotating rod presses the inclined plate upward, and the sorting head moves accordingly, gradually moving upward. The movement of the sorting head turns and sorts the solid materials in the molten bath furnace;

[0017] S3: During the production process of molten pool smelting, there will be poor fluidity in the molten pool furnace, which is not conducive to the subsequent metallurgical reaction of crude antimony. Spring 2 moves upward, and spring 2 cooperates with spring 1, connecting bar, and connecting plate to operate, causing the screen bar to gradually swing when it moves. The displacement of the screen bar changes the fluidity of the molten pool furnace;

[0018] S4: When the screen bars move, they push the plate to move, and the plate drives the arc to move synchronously. The arc acts on the thin layer, and the thin layer gradually covers the top of the molten pool furnace. The thin layer and the arc form a protection for the bottom to prevent the boiling of the molten solution and splashing to affect safety.

[0019] S5: In the process of protecting the molten solution, there may be a situation where the arc coverage is low, causing the solution to still splash to various parts during melting. The inclined plate is linked to the insert plate to move, and the insert plate drives the special supply strip to move through the sieve plate. The arc is affected and moves upward to increase the coverage distance;

[0020] S6: When the molten pool furnace needs to be cleaned, flush it directly into the water. When the water flow impacts, it gradually contacts the layer plates, which are affected and swing. The layer plates rotate around the shaft, pushing the vertical plates and the oblique body to move.

[0021] The beneficial effects of the present invention are as follows:

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] An embodiment of the present invention describes a device for producing crude antimony by smelting a molten pool of antimony oxide-containing materials, comprising a molten pool furnace 1, with fixed plates 2 fixedly connected to both sides of the molten pool furnace 1, a placement plate 3 fixedly connected to the rear end face of the molten pool furnace 1, a mounting seat 4 fixedly connected to the top of the placement plate 3, a telescopic cylinder 5 provided on the top of the mounting seat 4, a rotating rod 53 threadedly connected to the top of the telescopic cylinder 5, a servo motor provided in the mounting seat 4, the output end of the servo motor being connected to the rotating rod 53, an auxiliary component provided on the top of the telescopic cylinder 5, the auxiliary component being used to turn over the solid material in the molten pool, two screen bars 6 fixedly connected to the inside of the molten pool furnace 1, a flow component provided on the inner side of the two screen bars 6, the flow component being used to change the fluidity in the molten pool smelting.

[0037] like Figures 1 to 3 As shown, during operation, 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 an appropriate amount of oxidant is added to the molten pool furnace 1 for oxidation reaction, and then antimony oxide is obtained by roasting / smelting the sulfide ore, and crude antimony is produced by reduction smelting, and electrolytic refining and purification are carried out. During the process, a certain amount of solid material flux and auxiliary agent is 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 thick 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 component and the flow component. The auxiliary component gradually works. Through the setting of the auxiliary component, the auxiliary component is prompted to flip the solid material up or down, which is convenient for changing the position of the solid material in the molten pool furnace 1. In this process, the smelting temperature of the fluidity in the molten pool furnace 1 is changed through the setting of the flow component, 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, and a matching texture is provided 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, the top of the rotating rod 53 is rotatably connected to the inclined plate 54, and an insert disk 55 is fixedly connected to the lower end of the inclined plate 54 away from the other end of the inclined plate 54. A sorting head 56 is inserted into the center of the bottom end of the insert disk 55, and a fixing part 57 is sleeved on the outside of the insert disk 55. The telescopic cylinder 5 is connected to the insert disk 55 through the fixing part 57. The fixing part 57 is made of stainless steel and is fixed 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 material is melted first, and the top of the solid material is temporarily not melted. The bottom needs to be melted into liquid before the solid material 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 an embodiment of the present invention, the rotating rod 53 is energized and gradually moves upward or downward. The rotating rod 53 is pulled out from the inside of 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. The solid material in the molten pool furnace 1 is moved upward by the sorting head 56. The sorting head 56 promotes smelting by changing the position of the solid material, and at the same time facilitates the turning and sorting of the material in the molten pool furnace 1, thereby improving the general performance of use.

[0040] A displacement component is fixedly connected to the inner wall of the fixed plate 2, and the displacement component includes a processor 22 installed inside the molten pool furnace 1. The front end face of the molten pool furnace 1 is slidingly connected to the processor 22, and the rear end face of the processor 22 is fixedly connected to the central axis 23. The central axis 23 passes through the molten pool furnace 1, and the output end of the central axis 23 is fixedly connected to a connecting plate 24. The side of the connecting plate 24 away from the central axis 23 is elastically connected to a connecting bar 25, and the angle between the connecting bar 25 and the connecting plate 24 is ninety degrees. A sensor 26 is provided 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 links 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 cause a lateral displacement, the connecting bar 25 links the connecting plate 24 to operate, the connecting plate 24 moves toward the direction close to the telescopic cylinder 5, the connecting plate 24 links the central axis 23 to move, and when the central axis 23 moves, the screen bar 6 is driven to move synchronously, and the screen bar 6 gradually swings when it moves. The screen bar 6 will contact the top of the solid material during the movement, 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. A thin layer 63 is fixed between the two arcs 62. The thin layer 63 is made of stainless steel. Notches corresponding to the plug-ins 64 are opened on the thin layer 63. Multiple plug-ins 64 are inserted into the inner wall of the thin layer 63.

[0043] like Figures 4 and 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, and the splashing of the solution during boiling 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 member 61 to move, and the plate member 61 drives the arc member 62 to displace synchronously, and the arc member 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 member 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 fixed 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 fixed 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 side of the plurality of vertical plates 626 is fixed with an italic 627, and the italic 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. The inclined plate 54 will move in conjunction with the insert plate 55, and the insert plate 55 will move upward to drive the sieve plate 623 to move. The sieve plate 623 moves and drags the special supply strip 622 to move. The special supply strip 622 pulls the arc body 62 to move upward. The upward displacement of the arc body 62 increases the coverage distance, thereby enabling the equipment to quickly adjust the height and achieve 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 rotating shaft 624 as the rotating 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, ensuring the clean effect 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 producing crude antimony, sulfide ore is roasted / smelted to obtain antimony oxide, which is then reduced and smelted to produce crude antimony. A certain amount of solid material flux and additives are added, and when the rotating rod 53 is energized and moves upward, it gradually links the auxiliary components and the flow components.

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

[0050] S3: During the molten pool smelting process, the fluidity in the molten pool furnace 1 may be poor, which is not conducive to the subsequent metallurgical reaction of crude antimony. The second spring 52 moves upward. The second spring 52 cooperates with the first spring 20, the connecting bar 25, and the connecting plate 24 to cause the screen bars 6 to gradually swing when they move. The displacement of the screen bars 6 changes the fluidity of the molten pool furnace 1.

[0051] S4: When the screen bars 6 move, the screen bars 6 push 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 bath 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: During the process of protecting the molten solution, the arc 62 may have a low coverage area, causing the solution to 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 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. 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 axis, and the layer plate 625 pushes the vertical plate 626 and the oblique body 627 to move.

[0054] Working principle: During operation, before producing crude antimony, 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 squeezes 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 material in the molten pool furnace 1 is moved upward by the sorting head 56. The sorting head 56 promotes smelting by changing the position of the solid material, and at the same time facilitates the turning and sorting of the material in the molten pool furnace 1, thereby improving the general performance of use.

[0055] During the production of crude antimony, the rotating rod 53 is linked to 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 move horizontally. The connecting bar 25 is linked to the connecting plate 24 to operate, and the connecting plate 24 moves toward the direction close to the telescopic cylinder 5. The connecting plate 24 is linked to the central axis 23 to move. When the central axis 23 moves, the screen bars 6 are driven to move synchronously. When the screen bars 6 move, they gradually swing. When the screen bars 6 swing, they blow the molten solution in the bottom molten pool furnace 1. 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 crude antimony output.

[0056] There are safety issues in the process of producing crude antimony. The inclined plate 54 moves upward, and the inclined plate 54 is linked to the insert plate 55 to move. The insert plate 55 drives the sieve plate 623 to move upward. The sieve plate 623 moves and drags the special supply bar 622 to move. The special supply bar 622 pulls the arc body 62 to move upward. The upward displacement of the arc body 62 increases the coverage distance, thereby enabling the equipment to quickly adjust the height, preventing splashing molten solution from harming people or parts, and achieving the purpose of improving versatility.

[0057] After the process of producing crude antimony, after the things are cleaned up, they are directly rushed into the water. When the water flow hits, it gradually contacts the layer plate 625, and the layer plate 625 is affected and swings. The layer plate 625 rotates with the rotating shaft 624 as the rotating shaft. The layer plate 625 pushes the vertical plate 626 and the inclined body 627 to move. The inclined body 627 gradually cleans the inside of the molten pool furnace 1, ensuring the clean effect of the equipment and improving the convenience of cleaning.
