During the process, a differential rotation mechanism causes the adjusting frame and the central column to shift at an angle, driving the first and second supports to reciprocate. The movement of the first support adjusts the water spray state, allowing the water from the rotating spray pipe to more effectively cover the entire treatment container. Simultaneously, a wiping block prevents the spray pipe from being blocked by particles carried in the steam. Finally, a scraping mechanism is used to completely remove the slag from the inner wall of the treatment container.

Description

Technical Field

[0001] This invention belongs to the field of metal smelting technology, and specifically relates to a smelting apparatus for vanadium-titanium magnetite. Background Technology

[0002] Vanadium-titanium magnetite is a complex mineral composed primarily of iron, titanium, and vanadium, with multiple elements coexisting. It is not a single mineral, but rather an aggregate tightly intermingled with magnetite, ilmenite, and ilmenite crystals. The iron, titanium, and vanadium minerals are extremely fine-grained and intertwined, making physical separation very difficult. If only iron is smelted while titanium and vanadium are discarded as waste, it would not only be a huge waste of resources but also cause environmental problems. Therefore, smelting equipment is needed to refine and extract the ore. The smelting process requires the use of an electric arc furnace to melt the ore. After the vanadium-containing molten iron is separated, oxygen blowing can be used to oxidize the vanadium into slag. Finally, the vanadium slag and the devanadium-removed molten iron in the ladle are separated by skimming. During the skimming process, some slag will solidify on the ladle. In order to prevent the slag from covering the lining of the ladle, it is necessary to use a pneumatic hammer to remove the slag after the ladle has cooled. However, the adhesion between the completely solidified slag and the ladle is strong, making it difficult to remove the slag by hammering and difficult to achieve a complete removal effect. Therefore, it is necessary to design a vanadium-titanium magnetite smelting device. Summary of the Invention

[0008] As a further optimization of the present invention, the differential rotation mechanism includes an upper cover fixed to a closed cover plate. A rotary motor is provided on the top of the upper cover plate. The output end of the rotary motor is connected to a reducer. The output end of the reducer is fixedly connected to a transmission wheel. A first connecting belt is wound around the transmission wheel. The first connecting belt is wound around a first roller. The first roller is fixed to the top of a central column. The central column is rotatably connected to a closed ring. The closed ring is rotatably connected to the closed cover plate. A second roller is provided on the closed ring. A second connecting belt is tensioned on the second roller and the transmission wheel.

[0009] As a further optimization of the present invention, the telescopic adjustment mechanism includes an adjustment frame fixed in a closed ring, an adjustment groove is provided in the adjustment frame, and a first adjustment column and a second adjustment column are slidably connected in the adjustment groove. The first adjustment column is fixed on a first support and slidably connected to a central column. The second adjustment column is fixed on a second support and slidably connected to the central column.

[0010] As a further optimization of the present invention, the spraying mechanism includes an outer sleeve slidably connected to a first support, the outer sleeve being slidably connected to a water spray pipe, one end of the water spray pipe passing through a through hole on a central column to connect to an external water pipe, the external water pipe being fixed in the central column, an inner sleeve being fixedly provided on the outer wall of the external water pipe, the inner sleeve having a spiral groove, the outer sleeve being connected to the spiral groove through a protrusion on the inner wall, a water-distributing ball being provided on the outer sleeve, and a wiping block being provided on the side wall of the water-distributing ball.

[0011] As a further optimization of the present invention, the cleaning mechanism includes a cleaning frame slidably connected to a second bracket, and a support spring is provided between the cleaning frame and the second bracket.

[0012] As a further optimization of the present invention, the smelting mechanism includes a rotating support fixed on a lower support, a main support rotatably connected between the rotating supports, an electric arc melting furnace disposed in the main support, a side outlet disposed on one side of the electric arc melting furnace, and an iron tapping port disposed at the bottom of the electric arc melting furnace, a rotating support rotatably connected to the lower support, a motor reducer assembly disposed on the lower support, the output end of the motor reducer assembly being fixedly connected to the bottom of the rotating support, a first hydraulic cylinder disposed on the top of the rotating support, a first connecting frame disposed on the output end of the first hydraulic cylinder, a high-pressure bushing disposed on the first connecting frame, a second hydraulic cylinder disposed on the top of the rotating support, a second connecting frame being fixedly connected to the output end of the second hydraulic cylinder, and the second connecting frame being connected to the furnace cover by a chain.

[0013] As a further optimization of the present invention, the bottom of the lower support is provided with a guide rail, and an adjusting rack is slidably connected on the guide rail. The adjusting rack is connected to the output end of the tilting cylinder, the tilting cylinder is fixed on the lower support, and the adjusting rack is engaged with the tooth groove at the bottom of the main support.

[0014] As a further optimization of the present invention, the oxygen blowing mechanism includes a third hydraulic cylinder fixed on the lower support, the output end of the third hydraulic cylinder is fixedly connected to a third connecting frame, and an oxygen injection gun is provided on the third connecting frame.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. When cleaning slag on the treatment bag, the present invention sprays cold water onto the treatment bag through an external water pipe and a spray pipe. The difference in the coefficients of thermal expansion and contraction between the treatment bag and the slag causes the slag to detach from the treatment bag, which can reduce the impact force of the impact hammer and reduce the difficulty of slag removal. At the same time, the differential rotation mechanism will cause the adjustment frame and the central column to deviate at an angle. During the deviation, the first adjustment column will drive the first support to move closer to or away from the central column under the limiting action of the adjustment groove. With the help of the water distribution ball, the spray state of the spray pipe is adjusted so that the sprayed cold water can cover the entire inner wall of the treatment bag.

[0017] 2. During the process of the first support moving closer to or further away from the central column, the outer sleeve will rotate around the spiral groove under the limiting action of the first support. When the water-distributing ball passes through the inlet of the water spray pipe, the inlet of the water spray pipe can be cleaned by the wiping block to prevent the water spray pipe from being blocked by particles carried in the steam.

[0018] 3. When the differential rotation mechanism of the present invention drives the cleaning mechanism to rotate, the second adjusting column will drive the second bracket to move back and forth towards or away from the inner wall of the processing bag under the limiting action of the adjusting groove. In turn, in conjunction with the cleaning frame supported by the spring, it repeatedly contacts or separates from the inner wall of the processing bag. This avoids hard contact that could damage the inner lining of the processing bag, while adjusting the contact pressure between the cleaning frame and the inner wall of the processing bag, thus more effectively removing the slag adhering to the inner wall of the processing bag and achieving complete removal of the slag from the inner wall of the processing bag.

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example: Please refer to Figure 1-7A smelting apparatus for vanadium-titanium magnetite includes a lower support 1. A smelting mechanism 2 is installed on one side of the top of the lower support 1. The smelting mechanism 2 is used to hold the iron ore to be smelted. The iron ore is melted and layered in the smelting mechanism 2. Under the action of gravity sedimentation, the vanadium-containing molten iron settles at the bottom, while the high-titanium slag melt floats above the molten iron. After separation, the high-titanium slag melt can be crushed and magnetically separated to obtain metallic iron powder. The metallic iron powder can replace a small portion of the original iron ore and be reused in the smelting process of vanadium-titanium magnetite. An I-beam rail 3 is installed on the top of the lower support 1. A track trolley 4 (the track trolley 4 is prior art and will not be described in detail here) is installed on the track trolley 4. A processing bag 5 for receiving the vanadium-containing molten iron is placed on the track trolley 4. The top of the lower support 1 is equipped with... The oxygen blowing mechanism 6 is provided. When the rail trolley 4 moves the processing ladle 5 containing vanadium-containing molten iron to one side of the oxygen blowing mechanism 6, the oxygen blowing mechanism 6 introduces oxygen into the molten iron. The vanadium in the molten iron is oxidized and formed into vanadium slag, which is suspended on the vanadium-removed molten iron. The lower support 1 is equipped with a slag treatment mechanism 7. After oxygen blowing treatment, the vanadium slag and molten iron are separated by hoisting discharge and slag skimming. The separated vanadium slag can be used to extract metallic vanadium. The low-quality vanadium slag and solidified slag after the molten iron is discharged will solidify on the inner wall of the processing ladle 5. Then, it is hoisted back onto the rail trolley 4. The rail trolley 4 moves the processing ladle 5 to one side of the slag treatment mechanism 7 for slag treatment. The treated slag can be returned to the electric arc melting furnace 23 as a coolant to realize the internal circulation of solid residue and reduce the consumption of other coolants.

[0029] Please see Figure 1-2The smelting mechanism 2 includes symmetrically fixed rotating supports 21 on the lower support 1. A main support 22 is rotatably connected between the rotating supports 21 via bearings. An electric arc melting furnace 23 is housed in the main support 22. One side of the electric arc melting furnace 23 has a side outlet for discharging the upper layer of high-titanium slag melt, and the bottom of the electric arc melting furnace 23 has an iron tap for discharging vanadium-containing molten iron. A rotating support 24 is rotatably connected to one side of the lower support 1. A motor reducer assembly for driving the rotating support 24 is housed in the lower support 1. A first hydraulic cylinder 25 is located at the top of the rotating support 24. The output end of the first hydraulic cylinder 25... A first connecting frame is provided, on which a high-voltage bushing 26 is mounted. The high-voltage bushing 26 is connected to a high-voltage coil. During the process of the high-voltage bushing 26 being pressed into the electric arc melting furnace 23 by the first hydraulic cylinder 25, a large amount of heat is generated, which breaks down the iron ore and melts it in the electric arc melting furnace 23. A second hydraulic cylinder 27 is provided on the top of the rotating support 24. The output end of the second hydraulic cylinder 27 is fixedly connected to the second connecting frame. The second connecting frame is connected to the furnace cover 28 by a chain. During the smelting process, the furnace cover 28 is fastened to the electric arc melting furnace 23 for sealing and protection. A guide rail is provided at the bottom of the lower support 1. An adjusting rack 29 is slidably connected to the guide rail. The adjusting rack 29 is fixedly connected to the output end of the tilting cylinder 30, which is fixed to the lower support 1. The adjusting rack 29 is meshed with the tooth groove at the bottom of the main support 22. After the vanadium-titanium magnetite to be smelted in the production process is put into the electric arc melting furnace 23, the motor reducer set in the lower support 1 drives the rotating support 24 to rotate at a low speed, moving the furnace cover 28 above the electric arc melting furnace 23. Then, the second hydraulic cylinder 27 fastens the furnace cover 28 onto the electric arc melting furnace 23. The energized high-voltage bushing 26 is connected to the first hydraulic cylinder 25. The iron ore is pressed into the electric arc melting furnace 23 under the action of the furnace to melt it. After complete melting, a high-titanium slag melt is formed in the upper layer, and the lower layer is vanadium-containing molten iron. After complete stratification, the tilting cylinder 30 pushes the adjusting rack 29 to move. During the movement, the main support 22 is tilted by the tooth groove at the bottom of the main support 22, separating the high-titanium slag melt. After separation, the high-titanium slag melt can be crushed and magnetically separated to obtain metallic iron powder. The metallic iron powder can replace a small portion of the original iron ore and be put back into the smelting process of vanadium-titanium magnetite. The remaining vanadium-containing molten iron is discharged into the processing package 5 through the iron outlet at the bottom.

[0030] Please see Figure 1-2The oxygen blowing mechanism 6 includes a third hydraulic cylinder 61 fixed on the lower support 1. The output end of the third hydraulic cylinder 61 is fixedly connected to a third connecting frame. An oxygen spray gun 62 is installed on the third connecting frame. When the processing package 5 moves out of the main support 22 under the action of the track trolley 4 and moves to one side of the oxygen blowing mechanism 6, the third hydraulic cylinder 61 drives the oxygen spray gun 62 to move down and press into the vanadium-containing molten iron. The oxygen spray gun 62 blows oxygen to cause vanadium to oxidize into vanadium slag, which floats on the molten iron as semi-steel. After the oxygen blowing treatment, the vanadium slag and the vanadium-degraded molten iron are separated by hoisting and slag skimming. The separated vanadium slag can be used to extract metallic vanadium. The low-quality vanadium slag and solidified slag after the molten iron is discharged will solidify on the inner wall of the processing package 5, and then be hoisted back onto the track trolley 4.

[0031] Please see Figure 1-7 The slag treatment mechanism 7 includes a lifting hydraulic cylinder 71 fixed on the lower support 1. The output end of the lifting hydraulic cylinder 71 is fixedly connected to a closed exhaust mechanism 72. The lifting hydraulic cylinder 71 is used to drive the closed exhaust mechanism 72 to move up and down. The closed exhaust mechanism 72 is provided with a differential rotation mechanism 73. The differential rotation mechanism 73 is provided with a telescopic adjustment mechanism 74. The differential rotation mechanism 73 is provided with a spraying mechanism 75, a scraping mechanism 76 and an impact hammer 77. The spraying mechanism 75 and the scraping mechanism 76 are both connected to the telescopic adjustment mechanism 74. The spraying mechanism 75 can spray cold water onto the inner wall of the treatment bag 5. By utilizing the difference in thermal expansion and contraction coefficients between the treatment bag 5 and the slag, the slag is deformed and detached from the inner wall of the treatment bag 5. The slag still adhering to the treatment bag 5 is struck by the impact hammer 77. Finally, it is scraped by the rotating scraping mechanism 76 to completely remove the slag.

[0032] The closed exhaust mechanism 72 includes a lifting bracket 721 fixed on the output end of the lifting hydraulic cylinder 71. A closed cover plate 722 is provided at the bottom of the lifting bracket 721. The bottom of the closed cover plate 722 has a groove corresponding to the shape of the top of the processing package 5. A steam outlet 723 is symmetrically provided on one side of the top of the closed cover plate 722. The lifting hydraulic cylinder 71 drives the lifting bracket 721 to move down and completely fasten the closed cover plate 722 onto the processing package 5. During the spraying process of the spraying mechanism 75, a large amount of heat is generated, which causes the cold water to evaporate. The steam generated after evaporation can be collected through the steam outlet 723 and can be used to supply heat to the outside after stabilization.

[0033] The differential rotation mechanism 73 includes an upper cover 731 fixed to a closed cover plate 722. A rotary motor 732 is mounted on the top of the upper cover 731. The output end of the rotary motor 732 is connected to a reducer, and the output end of the reducer is fixedly connected to a transmission wheel 733. The upper cover 731 is used to enclose and protect the rotary motor 732 and the reducer. A first connecting belt 734 is wound around the transmission wheel 733. The first connecting belt 734 is wound around a first roller 735, and the first roller 735 is fixed to a central column. At the top of 736, the central column 736 is rotatably connected to the closed ring 737, and the closed ring 737 is rotatably connected to the closed cover plate 722. The closed ring 737 is provided with a second roller 738, and a second connecting belt 739 is tensioned on the second roller 738 and the transmission wheel 733. During the process of the rotary motor 732 driving the transmission wheel 733 to rotate through the reducer, the transmission wheel 733 can drive the first roller 735 and the second roller 738 to rotate at different speeds through the first connecting belt 734 and the second connecting belt 739 respectively.

[0034] The telescopic adjustment mechanism 74 includes an adjustment frame 741 fixed in a closed ring 737. An adjustment groove 742 is provided in the adjustment frame 741. A first adjustment column 743 and a second adjustment column 744 are slidably connected in the adjustment groove 742. The first adjustment column 743 is fixed on a first bracket 745. The first bracket 745 is slidably connected to a central column 736. As the closed ring 737 rotates with the second roller 738, it can drive the adjustment frame 741 to rotate synchronously, while the central column 736 will rotate with the first roller 735.

[0035] The spraying mechanism 75 includes an outer sleeve 751 slidably connected to a first bracket 745. The outer sleeve 751 is slidably connected to a water spray pipe 752. One end of the water spray pipe 752 passes through a through hole in the central column 736 and connects to an external water pipe 753. The external water pipe 753 is fixed in the central column 736. An inner sleeve 754 is fixedly installed on the outer wall of the external water pipe 753. A spiral groove 755 is opened on the inner sleeve 754. The outer sleeve 751 is connected to the spiral groove 755 through a protrusion on its inner wall. A water-distributing ball 756 is provided on the outer sleeve 751. A wiping block 757 is provided on the side wall of the water-distributing ball 756. During the differential rotation of the first roller 735 and the second roller 738, the adjusting frame 741 will have an angular offset from the central column 736. During the process, the first adjusting column 743 will drive the first support 745 to move back and forth towards or away from the central column 736 under the limiting action of the adjusting groove 742. During the movement, the water separating ball 756 will move back and forth towards or away from the nozzle of the spray pipe 752, thereby adjusting the spray state of the spray pipe 752 so that the sprayed cold water can cover the entire inner wall of the processing package 5. Through thermal expansion and contraction, the slag and the processing package 5 will be separated. At the same time, under the limiting action of the first support 745, the outer sleeve 751 can rotate and move around the spiral groove 755 through the cooperation of the protrusion on the inner wall and the spiral groove 755. When the water separating ball 756 passes through the nozzle of the spray pipe 752, it can be cleaned by the wiping block 757 to prevent the spray pipe 752 from being blocked by particles carried in the steam.

[0036] The cleaning mechanism 76 includes a cleaning frame 761 slidably connected to the second bracket 746. A support spring 762 is provided between the cleaning frame 761 and the second bracket 746. The second bracket 746 is slidably connected to the central column 736. The second adjusting column 744 is fixed to the second bracket 746. During the differential rotation of the first roller 735 and the second roller 738, the adjusting frame 741 will deviate angularly from the central column 736. During the deviation, the second adjusting column 744 will drive the second bracket 746 to move back and forth towards or away from the inner wall of the processing package 5 under the limiting action of the adjusting groove 742. In turn, the cleaning frame 761, which is elastically supported by the support spring 762, repeatedly contacts or separates from the inner wall of the processing package 5. This avoids hard contact that could damage the inner lining of the processing package 5, while adjusting the contact pressure between the cleaning frame 761 and the inner wall of the processing package 5, thus more effectively removing the slag adhering to the inner wall of the processing package 5.

[0037] It should be noted that, in the operation of this vanadium-titanium magnetite smelting apparatus, the vanadium-titanium magnetite to be smelted is first fed into the electric arc melting furnace 23. After the furnace cover 28 is fastened onto the electric arc melting furnace 23, the energized high-voltage bushing 26 is pressed into the electric arc melting furnace 23 to melt the iron ore. After complete melting, a high-titanium slag melt is formed in the upper layer, while the lower layer is vanadium-containing molten iron. After complete stratification, the electric arc melting furnace 23 is tilted to separate the high-titanium slag melt. The separated high-titanium slag melt can be crushed and magnetically separated to obtain metallic iron powder, which can replace a small portion of the original iron ore weight. The newly added vanadium-titanium magnetite smelting process; the vanadium-containing molten iron left behind is discharged into the processing pot 5 through the bottom tap hole; then the processing pot 5 is moved out of the main support 22 by the action of the track trolley 4 and moved to the side of the oxygen blowing mechanism 6 for oxygen blowing treatment to cause vanadium to oxidize into vanadium slag that floats on the molten iron as semi-steel. After oxygen blowing treatment, the vanadium slag and vanadium-degraded molten iron are separated by hoisting discharge and slag skimming. The separated vanadium slag can be used to extract metallic vanadium. The low-quality vanadium slag and solidified slag after the molten iron is discharged will solidify on the inner wall of the processing pot 5 and then be hoisted back onto the track trolley 4.

[0038] Then, the processing package 5 continues to move along the track trolley 4 to one side of the slag processing mechanism 7, and the sealing cover 722 is completely fastened onto the processing package 5. The differential rotation mechanism 73 drives the central column 736 and the adjusting frame 741 to rotate. During the rotation, the adjusting frame 741 will deviate angularly from the central column 736. During the deviation, the first adjusting column 743 will drive the first support 745 to move back and forth towards or away from the central column 736 under the limiting action of the adjusting groove 742. During the movement, the water-distributing ball 756 will move back and forth towards or away from the nozzle of the water spray pipe 752, thereby adjusting the water spray state of the water spray pipe 752. The molten slag is separated from the processing package 5 by thermal expansion and contraction. At the same time, the outer sleeve 751 rotates around the spiral groove 755. When the water separating ball 756 passes through the opening of the water spray pipe 752, it can be cleaned by the wiping block 757 to prevent the water spray pipe 752 from being blocked by particles carried in the steam. The molten slag that has not been separated is struck by the impact hammer 77 and finally cleaned by the rotating cleaning mechanism 76 to completely separate the molten slag. After being dried, the separated molten slag can be returned to the electric arc melting furnace 23 as a coolant to realize the internal circulation of solid residue and reduce the consumption of other coolants.

[0039] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
