Description

Technical Field

[0001] The invention belongs to the technical field of antimony reduction, in particular to an antimony reduction device. Background Art

[0002] Antimony is a Group V element in the periodic table, with a melting point of 630.5°C, a boiling point of 1638°C, and a density of 6.88 kg / m³. Antimony is widely used in the production of flame retardants, alloys, ceramics, glass, pigments, semiconductor components, pharmaceuticals, and chemicals. Currently, antimony production is primarily carried out through carbon reduction, typically using molten salt furnaces and electric arc furnaces.

[0003] A patent with publication number CN116907203A discloses an intelligent electric arc furnace for combined smelting and a method of using the same, which includes a base. Before using the intelligent electric arc furnace, the placement plate is first fixed to the furnace cover by engaging the rod and the socket, then the limit module 2 is opened, and the metal to be smelted is poured into the main body of the electric arc furnace, and then the servo motor is started to drive the reciprocating screw to rotate, so that the sliding sleeve can drive the placement plate 2 to move up and down in the slide groove, and then the arc assembly can be driven by the placement plate 2 to insert into the placement hole, and then the electric push rod 1 and the electric push rod 2 in the placement plate are started to push the relative limit plates close to each other to form a ring, and move them into the slot, so that the limit plates can block the gap between the arc assembly and the placement hole, thereby reducing the probability of sparks splashing outward during smelting to a certain extent.

[0004] There are still some problems in the actual application of the above scheme. When using the existing electric arc furnace, antimony ore needs to be added to the electric arc furnace first. At this time, the electric arc furnace cover needs to be rotated to separate the electric arc furnace cover from the top of the reactor before antimony ore can be added to the electric arc furnace. The electric arc furnace cover is connected to a connecting pipe for introducing reducing gas nitrogen, and the connecting pipe is divided into two sections, one of which is fixed to the electric arc furnace cover, and the other is connected to the nitrogen storage tank. Then the rotation of the electric arc furnace will separate the two pipes from each other, but at this time there is still a large amount of nitrogen left in the pipe connected to the nitrogen storage tank, which will cause these gases to leak, which will not only cause waste of nitrogen, but also cause environmental pollution to the surrounding working space and lead to increased production costs.

[0045] 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.

[0046] Example 1

[0047] like Figures 1 to 9 As shown, an antimony reduction device according to an embodiment of the present invention comprises a workbench 1, a storage box 2 is provided on one side of the workbench 1; a reactor 5 is mounted in the middle of the workbench 1, a base 56 is provided on one side of the reactor 5; a rotating table 55 is fixedly connected to the upper surface of the base 56, a first furnace cover 54 is fixedly connected to the circumferential surface of the rotating table 55; a base 63 is fixedly connected to the upper surface of the workbench 1, a support frame 6 is fixedly connected to the upper surface of the base 63, a connecting plate 62 is slidably provided on one side of the support frame 6 corresponding to the reactor 5, a plurality of arc columns 61 are fixedly connected to one end of the connecting plate 62 close to the reactor 5; collecting tanks 4 are provided on both sides of the reactor 5, a connecting table 31 is fixedly connected to the bottom end of the reactor 5, and a connecting table 31 is fixedly connected in the middle of the connecting table 31. A rotating shaft 3 is provided in the part, which is rotatably set in the workbench 1, and one end of the rotating shaft 3 is fixedly connected to the built-in motor of the workbench 1; a first connecting pipe 21 is fixedly connected to the upper surface of the storage box 2, and a second connecting pipe 24 is fixedly connected to the surface of the first furnace cover 54, and the first connecting pipe 21 is abutted against the second connecting pipe 24; a blocking piece is fixedly connected to the circumferential surface of the first connecting pipe 21 close to the second connecting pipe 24, and the blocking piece includes a fixed frame 22 fixedly connected to the circumferential surface of the first connecting pipe 21; and a positioning frame 23 fixedly connected to the upper surface of the fixed frame 22, a slide groove 26 is opened on the inner wall of the positioning frame 23, and a partition 25 is slidably set in the slide groove 26, and the partition 25 passes through the fixed frame 22 to block the first connecting pipe 21.

[0048] Specifically, in the process of using the above-mentioned electric arc furnace, antimony ore needs to be added to the electric arc furnace first. At this time, the electric arc furnace cover needs to be rotated to separate the electric arc furnace cover from the top of the reaction furnace 5 before antimony ore can be added to the electric arc furnace. The electric arc furnace cover is connected to a connecting pipe for introducing reducing gas nitrogen, and the connecting pipe is divided into two sections, one of which is fixed to the electric arc furnace cover, and the other is connected to the nitrogen storage tank 2. Then, the rotation of the electric arc furnace will separate the two pipes from each other. However, at this time, a large amount of nitrogen still remains in the pipe connected to the nitrogen storage tank 2, which will cause these gases to leak. This will not only cause a waste of nitrogen, but also cause environmental pollution to the surrounding work space and lead to increased production costs.

[0049] Therefore, the present invention can timely block the first connecting pipe 21 after the first furnace cover 54 is separated from the reactor 5 by setting a corresponding structure, thereby reducing the leakage of reducing gas nitrogen. When using the device for the first time, the built-in motor in the base 56 is started to drive the rotating platform 55 to rotate, thereby driving the first furnace cover 54 to rotate to one side, thereby separating from the reactor 5. After separating from the reactor 5, the staff adds antimony ore to the reactor 5. After the addition is completed, the rotating platform 55 is started again to drive the first furnace cover 54 to return to the top of the reactor 5, and then the connecting plate 62 in the support frame 6 is started to move downward, thereby driving the arc column 61 to be inserted into the reactor 5, and then the storage box 2 is started so that the storage box 2 can pass reducing gas nitrogen into the reactor 5. After nitrogen is introduced, the arc column 61 is started. An arc is generated between the arc columns 61 through the air, thereby generating high temperature in the reaction arc, thereby reducing the antimony ore in the reactor 5. When the reaction is completed, the arc column 61 needs to be lifted, and then the first furnace cover 54 is rotated. However, at this time, a large amount of nitrogen is still present in the first connecting pipe 21. If the first furnace cover 54 is moved, it will lead to waste and leakage of nitrogen. Therefore, the partition 25 in the positioning frame 23 is lowered by electrical control and made to slide along the slide groove 26, thereby blocking the end of the first connecting pipe 21. Then, when the first furnace cover 54 is rotated to drive the second connecting pipe 24 to rotate, the nitrogen in the first connecting pipe 21 will not leak into the air, thereby achieving the effect of protecting the working environment and saving a certain amount of nitrogen.

[0050] This solves the problem that nitrogen leakage may cause environmental pollution to the surrounding work space and increase production costs.

[0051] like Figure 5 As shown, in this embodiment, the fixed frame 22 is fixedly connected to a side of the second connecting tube 24 with an electric control shaft 27, the circumferential surface of the electric control shaft 27 is fixedly connected to an auxiliary ring 29, and the fixed frame 22 is fixedly connected to the position of the auxiliary ring 29 with a fixing ring 28, and the fixing ring 28 and the auxiliary ring 29 can seal and clamp the second connecting tube 24.

[0052] Specifically, each time the first furnace cover 54 is rotated, thereby driving the second connecting pipe 24 to rotate, there will be a certain gap at the connection between the first connecting pipe 21 and the second connecting pipe 24, and some nitrogen may leak out. Therefore, a fixing ring 28 is fixed to the end of the first connecting pipe 21. The arc of the fixing ring 28 is larger than the first connecting pipe 21, so that it can cover the second connecting pipe 24. Before rotating the first furnace cover 54, the electric control shaft 27 is rotated to drive the auxiliary ring 29 to rotate. After releasing the second connecting pipe 24, the first furnace cover 54 can be rotated. The auxiliary ring 29 fits with the fixing ring 28, thereby achieving the effect of sealing the connection between the first connecting pipe 21 and the second connecting pipe 24.

[0053] like Figure 6 and Figure 7 As shown, a support plate 57 is fixedly connected to one side of the reactor 5 of this embodiment, and a discharge pipe 58 is fixedly connected to the lower surface of the support plate 57. The discharge pipe 58 is a three-way pipe, and one end of the discharge pipe 58 is fixedly connected to the reactor 5. The upper end of the discharge pipe 58 is threadedly connected to a rotating handle 59, and the bottom end of the rotating handle 59 is fixedly connected to a connecting rod 513. The connecting rod 513 is located in the middle of the discharge pipe 58.

[0054] Specifically, after the reduction of the antimony ore in the reactor 5 is completed, the threaded handle is rotated to drive the connecting rod 513 to move upward, and then the connecting rod 513 is separated from the middle part of the three-way discharge pipe 58, that is, the discharge pipe 58 is opened, so that the molten antimony flows out of the reactor 5 and is then collected uniformly by the collection tank 4.

[0055] like Figure 8 As shown, a connecting rope 510 is wrapped around the middle of the rotating handle 59 of this embodiment, and a blocking plate 511 is fixedly connected to the end of the connecting rope 510 away from the rotating handle 59. The cross-section of the blocking plate 511 is "T"-shaped, and a spring 512 is fixedly connected between the blocking plate 511 and the reactor 5.

[0056] Specifically, when the handle 59 is rotated, the connecting rope 510 will be reeled in. During the process of reeling in the connecting rope 510, the connecting rope 510 will pull the blocking plate 511, thereby driving the blocking plate 511 to move out of the reactor 5. During the process of pulling the blocking plate 511, both ends of the blocking plate 511 will be fixed to the reactor 5 through the spring 512, so that the blocking plate 511 will not be completely pulled out of the reactor 5, and then the three-way discharge pipe 58 and the discharge port of the reactor 5 can be opened at the same time, so that the molten antimony can flow out.

[0057] like Figure 1 and Figure 7 As shown, a positioning frame 51 is fixedly connected to the other side of the reactor 5 in this embodiment. The positioning frame 51 is concave, and positioning guide rails 52 are provided on both sides of the positioning frame 51. Positioning guide blocks 53 are slidably provided in the positioning guide rails 52. A discharge port 514 is provided at the position of the reactor 5 corresponding to the positioning guide blocks 53.

[0058] Specifically, after a certain amount of molten antimony is discharged from the discharge pipe 58, some impurity oxides or residues will be formed during the smelting process. These substances may float on the surface of the molten antimony and cannot be discharged through the discharge pipe 58. The handle 59 is turned to close the discharge pipe 58, and then the positioning guide block 53 is started to move the positioning guide block 53 upward along the positioning guide rail 52, so that the discharge port 514 of the reactor 5 can be opened. Then, the connecting platform 31 is driven to tilt by starting the rotating shaft 3, thereby driving the reactor 5 to tilt and discharge these floating objects from the discharge port 514 to the reactor 5.

[0059] Example 2

[0060] like Figures 2 to 9 As shown, comparative example 1, another embodiment of the present invention is: a positioning platform 7 is fixedly connected to the upper surface of the workbench 1, a limiting frame 71 is rotatably provided on the upper surface of the positioning platform 7, a first guide rail 73 is provided inside the limiting frame 71, a guide rod 74 is slidably provided in the first guide rail 73, a second furnace cover 72 is fixedly connected to one end of the guide rod 74 away from the limiting frame 71, and a plurality of cleaning rollers 712 are rotatably provided on the lower surface of the second furnace cover 72.

[0061] Specifically, after the reduction and unloading of antimony are completed, since there is still a certain amount of antimony and some floating residues remaining on the inner wall of the reactor 5, if they are not cleaned, these substances will be mixed into the antimony to be reduced next time. Therefore, it is necessary to clean the reactor 5. First, the built-in motor of the positioning platform 7 is started to drive the limit frame 71 to rotate toward the side close to the reactor 5. At this time, the first furnace cover 54 and the arc column 61 have both rotated to the side away from the second furnace cover 72. Then the limit frame 71 will drive the second furnace cover 72 to rotate to the top of the reactor 5, and then drive the guide rod 74 along the first guide rail 73 to drive the second furnace cover 72 to be inserted into the reactor 5, and then start the several cleaning rollers 712 on the lower surface of the second furnace cover 72 to rotate while rotating around the inner wall of the reactor 5, thereby achieving the effect of cleaning the inner wall.

[0062] like Figure 4 As shown, in this embodiment, a first motor 76 is provided on the upper surface of the second furnace cover 72, and a first gear 78 is fixedly connected to the output end of the first motor 76. The first gear 78 is meshed with a second gear 79, and a fixed tube 710 is fixed to the middle part of the second gear 79. A planetary gear set 714 is provided on the circumferential surface of the fixed tube 710, and the planetary gear set 714 is provided on the lower surface of the second furnace cover 72.

[0063] Specifically, the rotation of the lower surface of the second furnace cover 72 is achieved by starting the first motor 76 on the upper surface of the second furnace cover 72. After the first motor 76 rotates, it drives the first gear 78 to rotate. After the first gear 78 rotates, it drives the second gear 79 meshing with it to rotate. The second gear 79 drives the fixed tube 710 to rotate. The rotation of the fixed tube 710 drives the planetary gear set 714 arranged on the lower surface of the second furnace cover 72 and its circumferential surface to rotate. The planetary gear set 714 is fixedly connected to each cleaning roller 712, thereby driving each cleaning roller 712 to rotate. Figure 4 shown.

[0064] like Figure 4 As shown, a water tank 75 is provided on the upper surface of the second furnace cover 72 of this embodiment. The water tank 75 is rotatably connected to the fixed pipe 710. A plurality of spray holes 715 are opened on the circumferential surface of the fixed pipe 710. A pressure pump 77 is provided on the upper surface of the water tank 75.

[0065] Specifically, when the cleaning roller 712 cleans the inner wall of the reaction furnace 5, a water tank 75 is provided on the upper surface of the second furnace cover 72, and then the fixed pipe 710 is rotatably connected to the water tank 75, and then the water or detergent in the water tank 75 is pressurized into the fixed pipe 710 through the pressure pump 77 on the water tank 75, and then sprayed out through several spray holes 715 on the circumferential surface of the fixed pipe 710, thereby assisting the cleaning roller 712 to perform a better cleaning work.

[0066] like Figure 3 As shown, in this embodiment, the water tank 75 is fixed with a sealing ring 711 at the position corresponding to the fixed pipe 710, and the fixed pipe 710 is rotatably connected to the water tank 75 through the sealing ring 711.

[0067] Specifically, a sealing ring 711 is fixed at the connection between the fixed pipe 710 and the water tank 75, so that the pressure pump 77 can maintain the sealing of the connection between the fixed pipe 710 and the water tank 75 when pressurizing water or detergent into the fixed pipe 710, preventing leakage of water or detergent and affecting the normal use of other components.

[0068] like Figure 4 As shown, in this embodiment, a scraper 713 is fixed to the bottom end of the fixed tube 710 , and the scraper 713 abuts against the bottom wall of the reaction furnace 5 .

[0069] Specifically, when the fixed tube 710 rotates, the scraper 713 at the bottom will also rotate, and then the water or detergent sprayed on the inner wall of the reaction will flow to the bottom wall, and then the scraper 713 can perform a simple cleaning of the bottom wall of the reactor 5, thereby ensuring better subsequent reaction work.

[0070] Working principle: when the device is first used, the built-in motor in the bottom platform 56 is started to drive the rotating platform 55 to rotate, thereby driving the first furnace cover 54 to rotate to one side, thereby separating from the reactor 5. After separating from the reactor 5, the staff adds antimony ore to the reactor 5. After the addition is completed, the rotating platform 55 is started again to drive the first furnace cover 54 to return to the top of the reactor 5, and then the connecting plate 62 in the support frame 6 is started to move downward, thereby driving the arc column 61 to be inserted into the reactor 5, and then the storage box 2 is started so that the storage box 2 can pass the reducing gas nitrogen into the reactor 5. After the nitrogen is passed, the arc column 61 is started again. An arc is generated between the arc columns 61 through the air, thereby generating high temperature in the reaction arc, thereby reducing the antimony ore in the reactor 5. When the reaction is completed, the arc column 61 needs to be lifted, and then the first furnace cover 54 is rotated. In the process of rotating the first furnace cover 54 to drive the second connecting pipe 24 to rotate, there will be a certain gap at the connection between the first connecting pipe 21 and the second connecting pipe 24. Some nitrogen may leak out, so a fixing ring 28 is fixed to the end of the first connecting tube 21. The arc of the fixing ring 28 is larger than that of the first connecting tube 21, so that it can cover the second connecting tube 24. Before rotating the first furnace cover 54, the electric control shaft 27 is first rotated to drive the auxiliary ring 29 to rotate. After the second connecting tube 24 is released, the first furnace cover 54 can be rotated. The auxiliary ring 29 fits with the fixing ring 28, thereby achieving the effect of sealing the connection between the first connecting tube 21 and the second connecting tube 24. However, when the first furnace cover 54 is rotated, a large amount of nitrogen still remains in the first connecting tube 21. Moving the first furnace cover 54 will cause nitrogen waste and leakage. Therefore, the partition 25 in the positioning frame 23 is lowered by electrical control and slides along the slide groove 26, thereby blocking the end of the first connecting tube 21. Then, when the first furnace cover 54 is rotated to drive the second connecting tube 24 to rotate, the nitrogen in the first connecting tube 21 will not leak into the air, thereby achieving the effect of protecting the working environment and saving a certain amount of nitrogen.

[0071] Then, by rotating the threaded handle, the connecting rod 513 is driven to move upward, and then the connecting rod 513 is separated from the middle part of the three-way discharge pipe 58, that is, the discharge pipe 58 is opened. When the handle 59 is rotated, the connecting rope 510 is wound up. During the winding process of the connecting rope 510, the connecting rope 510 pulls the blocking plate 511, thereby driving the blocking plate 511 to move out of the reactor 5. During the pulling process of the blocking plate 511, the two ends of the blocking plate 511 are fixed to the reactor 5 by the spring 512, so that the blocking plate 511 will not be completely pulled out of the reactor 5. Then, the three-way discharge pipe 58 and the discharge port of the reactor 5 can be opened at the same time, so that the molten antimony can flow out.

[0072] After a certain amount of molten antimony is discharged from the discharge pipe 58, some impurity oxides or residues may float on the surface of the molten antimony during the smelting process and cannot be discharged through the discharge pipe 58. The rotary handle 59 is then turned to close the discharge pipe 58, and the positioning guide block 53 is then activated to move upward along the positioning guide rail 52, thereby opening the discharge port 514 of the reaction furnace 5. The connecting platform 31 is then tilted by activating the rotating shaft 3, thereby tilting the reaction furnace 5 to discharge these floating objects from the discharge port 514.

[0073] After the reduction and discharge of antimony are completed, since there is still a certain amount of antimony and some floating residues on the inner wall of the reactor 5, if they are not cleaned, these substances will be mixed into the antimony to be reduced next time. Therefore, it is necessary to clean the reactor 5. First, the built-in motor of the positioning platform 7 is started to drive the limit frame 71 to rotate toward the side close to the reactor 5. At this time, the first furnace cover 54 and the arc column 61 have been rotated to the side away from the second furnace cover 72. Then the limit frame 71 will drive the second furnace cover 72 to rotate to the top of the reactor 5, and then drive the guide rod 74 along the first guide rail 73 to drive the second furnace cover 72 to be inserted into the reactor 5, and then start the second furnace cover 72 on the upper surface of the second furnace cover 72. A motor 76, after the first motor 76 rotates, it will drive the first gear 78 to rotate. After the first gear 78 rotates, it will drive the second gear 79 meshing with it to rotate. The second gear 79 will drive the fixed tube 710 to rotate. The rotation of the fixed tube 710 drives the planetary gear set 714 arranged on the lower surface of the second furnace cover 72 and its circumferential surface to rotate. The planetary gear set 714 is fixedly connected to each cleaning roller 712, so that it can drive each cleaning roller 712 to rotate. The multiple cleaning rollers 712 on the lower surface of the second furnace cover 72 can rotate while rotating around the inner wall of the reaction furnace 5, thereby achieving the effect of cleaning the inner wall. Figure 4 As shown, when the cleaning roller 712 cleans the inner wall of the reaction furnace 5, a water tank 75 is provided on the upper surface of the second furnace cover 72, and then the fixed pipe 710 is rotatably connected to the water tank 75, and then the water or detergent in the water tank 75 is pressurized into the fixed pipe 710 through the pressure pump 77 on the water tank 75, and then sprayed out through a plurality of spray holes 715 on the circumferential surface of the fixed pipe 710, thereby assisting the cleaning roller 712 to perform a better cleaning work.
