Description

Technical Field

[0001] This invention relates to the field of titanium-rich material preparation technology, and in particular to a continuous reaction system for preparing titanium-rich materials based on the reduction corrosion method. Background Technology

[0002] Synthetic rutile is produced from titanium concentrate using metallurgical or chemical methods to remove iron oxide, thereby improving its TiO2 grade. In general, there are three main production methods: one is to remove iron oxide directly or after pretreatment (such as pre-oxidation or pre-reduction) of the titanium concentrate by acid leaching; another is smelting and melting reduction, separating the iron oxide from the titanium concentrate into metallic iron, resulting in high-titanium slag; and the third is to first reduce the iron oxide in the titanium concentrate, then use electrochemical etching to separate the metallic iron from the ore particles, followed by washing and drying to obtain synthetic rutile produced by reduction etching. The traditional reduction etching process for synthetic rutile uses titanium concentrate as raw material, undergoing pre-oxidation, reduction etching, washing, and drying. This process was first developed by the Australian National Chemical Research Institute in 1961 and has since been gradually applied to production. Currently, Australia's ILUKA has built a production plant for synthetic rutile produced by the reduction etching method with an annual capacity of 500,000 tons. In the 1970s, my country's Ministry of Metallurgical Industry's Changsha Institute of Mining and Metallurgy began research on synthetic rutile produced by the reduction etching method, and subsequently put it into production in Beihai, Guangxi; Zhuzhou, Hunan; Qinzhou, Guangxi; and Zhenjiang, Jiangsu. Due to limitations in process conditions, the original reduction etching method for synthetic rutile generally had a TiO2 content of less than 92%, which could not meet the demand for high-grade synthetic rutile in some fields.

[0003] A process for improving the grade of TiO2 in synthetic rutile produced by reduction etching, disclosed in CN108217722A, includes the following steps: Step 1: Selecting high-grade coastal altered titanium concentrate with TiO2 ≥ 56%, and performing stepwise magnetic separation and high-voltage electrostatic separation on the titanium concentrate; Step 2: Feeding the titanium concentrate obtained in Step 1 into a rotary kiln for high-temperature negative pressure sealed reduction; Step 3: Using the high-temperature material from the reduction kiln, high-temperature steam is generated through a heat exchanger and introduced into the etching tank to control the metallic iron content below 0.3%; Step 4: Washing the etched titanium-rich material using a combination of a horizontal spiral classifier, a vertical spiral chute, and a vacuum belt filter press; Step 5: First, acid leaching the washed titanium-rich material with 10-15% dilute hydrochloric acid; then adding 2-5% diluted hydrofluoric acid for 0.5-1 hour; Step 6: Drying the titanium-rich material obtained in Step 5, and then performing dry magnetic separation to obtain the final product. This method does not require pelletizing, crushing, or grinding, nor does it require pre-oxidation treatment. The raw material processing before reduction is simple and low-cost. The application document states that the preparation of titanium-rich materials does not require pelletizing, crushing, and grinding operations. However, the untreated ore still contains large particles after high-temperature reduction, which is not suitable for the candidate corrosion leaching operation. At the same time, the application document cannot realize the continuous feeding, corrosion, leaching, and unloading operations of titanium-rich materials. Therefore, a continuous reaction system for preparing titanium-rich materials based on the reduction corrosion method is proposed. Summary of the Invention

[0004] To address the technical problem that the application does not utilize candidate corrosion leaching operations and cannot achieve continuous feeding, corrosion, leaching, and unloading of titanium-rich materials, this invention provides a continuous reaction system for producing titanium-rich materials based on a reduction corrosion method.

[0005] This invention is achieved using the following technical solution: a continuous reaction system for preparing titanium-rich materials based on a reduction corrosion method, comprising: The rust leaching assembly has an open annular reaction tank at the top, an isolation vibration mechanism fixed to the inner wall of the bottom of the reaction tank for adjusting the vibration of the raw material, and an rust leaching tank and a leaching tank for leaching the raw material fixed to the outer ring of the isolation vibration mechanism, which are connected to the reaction tank. The lifting and conveying assembly includes a disc-shaped top plate, a ring-shaped lifting and adjusting mechanism for adjusting the height of materials fixed to the bottom of the top plate, and a conveying mechanism for conveying materials disposed in the inner ring of the lifting and adjusting mechanism. The material storage assembly includes a connecting frame for connection with a conveying mechanism, a base plate fixed to the bottom of the connecting frame, multiple sets of storage units for storing raw materials arranged vertically in sequence on the bottom of the base plate, outer support rods fixed to both ends of one side of the base plate, an opening and closing mechanism for adjusting the opening and closing of the storage units mounted on the two sets of outer support rods, inner support rods fixed to both ends of the other side of the base plate, and an attitude adjustment mechanism for adjusting the tilting attitude of the storage units mounted on the two sets of inner support rods. The support adjustment assembly includes a support plate with an annular structure fixed to the top of the reaction tank, and a drive adjustment mechanism disposed in the inner ring of the support plate for driving the opening and closing mechanism to start.

[0006] Through the above technical solution, the material storage component without raw materials is transported to the material conveying channel position in the support and adjustment component. Then, the support and adjustment component and the isolation vibration mechanism are activated to adjust the tilt and opening / closing state of the storage unit in the material storage component. After the material is loaded, the conveying mechanism and the lifting and adjustment mechanism are activated to transport the material storage component containing raw materials to the corrosion tank and leaching tank in sequence under the guidance of the isolation vibration mechanism and the support and adjustment component for corrosion and leaching operations. After the corrosion and leaching operations of the raw materials are completed, the material is transported back to the conveying channel position for unloading operations.

[0007] As a further improvement to the above solution, the isolation oscillation mechanism includes a ring-shaped partition, two sets of storage slots arranged along the length of the partition on the top of the partition, a circular arc-shaped push plate slidably sleeved on the storage slots, a push unit fixed to one side of the push plate and the partition, a trapezoidal retaining plate fixed to the top of the partition between the two ends of the storage slots, a storage slot arranged along the length of the retaining plate at the middle of the top of the retaining plate, a circular arc-shaped push plate slidably sleeved on the storage slot, and a push unit fixed to one side of the push plate and the retaining plate.

[0008] Through the above technical solution, the push-pull frame abuts against the top of the push plate, and then the push unit starts to move back and forth, causing the push-pull frame to move up and down, thereby causing the storage unit to rotate up and down along the end of the transfer pipe. When the storage unit rotates up and down, the raw material inside the storage unit vibrates up and down, causing the reaction liquid in the rust tank and leaching tank to quickly come into contact with the raw material, quickly flushing the raw material and improving the reactivity efficiency and quality.

[0009] As a further improvement to the above solution, the lifting and adjusting mechanism includes a second support plate with an annular structure fixed to the top plate, two sets of top retaining channels with arc-shaped structures arranged coaxially on the outer ring of the second support plate, a bottom retaining channel located on the outer ring of the second support plate at the bottom between the two sets of top retaining channels, and a compression channel communicating with the end of the adjacent bottom retaining channel at both ends of the two sets of top retaining channels.

[0010] As a further improvement to the above solution, the conveying mechanism includes a chain with an annular structure disposed in the inner ring of the lifting and adjusting mechanism. The bottom of the chain is connected to a sprocket that is movably sleeved with the lifting and adjusting mechanism. One end of the sprocket extending out of the lifting and adjusting mechanism is equipped with a motor. An L-shaped connecting rod is fixedly connected to the chain. The bottom of the connecting rod is slidably sleeved with a movable tube fixedly connected to the top of the connecting frame. One side of the movable tube is fixedly connected to a push rod fixedly connected to the top of the connecting frame. The top of the push rod is fixedly connected to a roller that is slidably connected with the lifting and adjusting mechanism.

[0011] With the above technical solution, when the motor on the conveying mechanism is started, the sprocket drives the chain to move, and then the chain drives the connecting rod to move, thereby driving the movable tube and the bottom connecting frame to move. During the movement, the push rod moves sequentially along the top holding channel, the extrusion channel, the bottom holding channel, the extrusion channel, and the top holding channel on the two side walls of the support plate. When feeding, the roller on the push rod is located on the top holding channel, and the storage assembly is in the upper position. When moving with the conveying mechanism, it moves along the extrusion channel to the bottom holding channel. At this time, the storage assembly slides down and moves to the corrosion tank for corrosion. At the same time, the opening and closing mechanism on the storage assembly slides along the top holding channel to the bottom holding channel, so that the storage assembly always remains in the closed state during the operation.

[0012] As a further improvement to the above solution, the storage unit includes a U-shaped support plate with an opening at the top. An inner wall sealing plate is fixedly connected to the opening on the side of the support plate near the inner support rod, and an outer wall sealing plate is rotatably connected to the opening on the side of the support plate near the outer support rod.

[0013] As a further improvement to the above solution, the opening and closing mechanism includes two sets of hollow support rods arranged vertically. Each set of support rods has an L-shaped adapter pipe fixedly connected to the end near the storage unit, which is slidably sleeved with the outer wall of the storage unit. An adapter unit 1 is installed inside the adapter pipe along its length. An isolation cover fixedly connected to the storage unit is slidably sleeved on the outer ring of the adapter pipe near the storage unit. An adapter unit 2 connected to the adapter unit 1 and the storage unit is installed inside the isolation cover. An L-shaped push-pull rod 1 that slides along its length is slidably sleeved on the top of the support rod. A rotating tube that is movably sleeved with the inner wall of the end of the support rod is threaded into the end of the push-pull rod 1, and the rotating tube is connected to the adapter unit 1.

[0014] Through the above technical solution, the two sets of push-pull rods on the opening and closing mechanism of the storage component move to the drive plate in the mounting groove on the top holding channel 2 of the drive adjustment mechanism. When the push unit 2 is started, the drive plate moves vertically, and then the push-pull rod 1 moves vertically. When the push-pull rod 1 moves, the rotating tube rotates under the action of the thread, and then the bevel gear 4 rotates. After that, under the action of the transfer unit 1, the transfer unit 2 rotates. Finally, the rotating shaft 3 on the transfer unit 2 drives the outer wall sealing plate to deflect when it rotates. When the outer wall sealing plate deflects, the opening and closing operation of the storage unit is realized.

[0015] As a further improvement to the above solution, the attitude adjustment mechanism includes an L-shaped push-pull frame disposed on the side of the inner support rod away from the storage unit. Both sides of the push-pull frame are hinged with L-shaped push-pull rods that are movably connected to the outer wall of the adjacent storage unit. The push-pull frame is slidably sleeved with a retaining plate fixed to the inner support rod.

[0016] Through the above technical solution, the material storage component enters the rust tank and leaching tank downwards. The push-pull bracket on the attitude adjustment mechanism abuts against the top of the push plate one, and then the push unit one starts to reciprocate, driving the push-pull bracket to move up and down. When the push-pull bracket moves up and down, it drives the push-pull rod two to move, thereby driving the storage unit connected to it to rotate up and down along the end of the transfer pipe. When the storage unit rotates up and down, the raw material inside the storage unit vibrates up and down, so that the reaction liquid in the rust tank and leaching tank quickly comes into contact with the raw material, quickly flushing the raw material and improving the reaction efficiency and quality.

[0017] As a further improvement to the above solution, the first adapter unit includes a rotating shaft 1 disposed inside the adapter tube and movably sleeved with the storage unit. A bevel gear 1 is fixedly sleeved at one end of the rotating shaft 1 away from the storage unit. A bevel gear 2 meshes with one side of the bevel gear 1. The inner ring of the bevel gear 2 is fixedly sleeved with the rotating shaft 2. A bearing ring that movably sleeves with the adapter tube is movably sleeved on the outer ring of the rotating shaft 2. A bevel gear 3 is fixedly sleeved at the other end of the rotating shaft 2. A bevel gear 4 that is fixedly sleeved with the rotating tube meshes with one side of the bevel gear 3.

[0018] As a further improvement to the above solution, the second transfer unit includes a toothed belt disposed on the isolation cover. The inner ring of the toothed belt is connected to a pulley 1 and a pulley 2. A rotating shaft 3 connected to the storage unit is fixedly sleeved on the pulley 1, and the pulley 2 is fixedly sleeved on the transfer unit 1.

[0019] Through the above technical solution, when the push-pull rod moves, the rotating tube rotates under the action of the thread, and then the bevel gear rotates. Subsequently, under the action of the transfer unit 1, the transfer unit 2 rotates. Finally, when the rotating shaft 3 on the transfer unit 2 rotates, it drives the outer wall sealing plate to deflect. When the outer wall sealing plate deflects, the opening and closing operation of the storage unit is realized.

[0020] As a further improvement to the above solution, the drive adjustment mechanism includes two sets of arc-shaped top holding channels II coaxially arranged on the support plate I. A bottom holding channel II is opened at the bottom between the two sets of top holding channels II, located on the inner side wall of the support plate I. A conveying channel is set directly below one of the top holding channels II and passes through the support plate I. The top of the conveying channel has an installation groove extending upward along the height direction of the support plate I, and the installation groove is connected to the top holding channel II. An adjustment mechanism is installed inside the two sets of installation grooves. An adjustment channel I is opened at both ends of the two sets of top holding channels II, symmetrically arranged along them, and the adjustment channel I is connected to the adjacent bottom holding channel II. An adjustment channel II is opened on the side of the two sets of adjustment channels I that are close to each other. One end of the adjustment channel II is connected to the end of the bottom holding channel II, and the other end of the adjustment channel II is connected to the top holding channel II. The adjustment channel I is arranged parallel to the adjacent adjustment channel II.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention simultaneously adjusts the tilt and opening / closing states of multiple storage units for storing raw materials during the loading and unloading process, enabling rapid loading and unloading of raw materials, facilitating loading and unloading operations during the preparation of titanium-rich materials, and improving loading and unloading efficiency.

[0022] This invention enables continuous operation of feeding, rusting, leaching, and unloading of reducing materials in the process of preparing titanium-rich materials by reduction rusting. At the same time, the raw materials are shaken during the rusting and leaching processes to ensure that the raw materials are in full contact with the reaction solution during the shaking process, so that the reaction solution can quickly wash the raw materials, thereby improving the efficiency and quality of rusting and leaching, improving the efficiency and quality of titanium-rich material preparation, and reducing the operational difficulty in the preparation process.

[0037] Working principle: The material storage component 4 without raw materials is transported to the material conveying channel 25 in the support adjustment component 2 by the conveying mechanism 8 and the lifting adjustment mechanism 7. Then, the support adjustment component 2 and the isolation vibration mechanism 5 are started to adjust the tilt and opening / closing state of the storage unit 45 in the material storage component 4. After that, the material is loaded. After the material is loaded, the conveying mechanism 8 and the lifting adjustment mechanism 7 are started to transport the material storage component 4 containing raw materials to the rust tank 61 and the leaching tank 62 in sequence under the guidance of the isolation vibration mechanism 5 and the support adjustment component 2 for rusting and leaching operations. After the rusting and leaching operations of the raw materials are completed, the material is transported to the material conveying channel 25 again for unloading. During the conveying process, the motor on the conveying mechanism 8 starts, causing the sprocket to drive the chain. The chain then drives the connecting rod, which in turn moves the movable tube and the bottom connecting frame 41. During this movement, the push rod moves sequentially along the top holding channel 72, the extrusion channel 74, the bottom holding channel 73, the extrusion channel 74, and the top holding channel 72 on the side wall of the support plate 71. During material loading, the roller on the push rod is positioned on the top holding channel 72, at which point the material storage assembly 4 is in the upper position. As it moves with the conveying mechanism 8... The material storage assembly 4 moves along the extrusion channel 74 to the bottom holding channel 73. At this time, the material storage assembly 4 slides down and moves into the corrosion tank 61 for corrosion. At the same time, the opening and closing mechanism 47 on the material storage assembly 4 slides along the top holding channel 23 to the bottom holding channel 24, so that the material storage assembly 4 is always kept in the closed state during operation. Meanwhile, the attitude adjustment mechanism 46 on the material storage assembly 4 slides along the top of the isolation vibration mechanism 5 and moves along the holding plate 54 to the receiving groove 52 of the partition plate 51, so that the attitude adjustment mechanism 46 does not cause the material storage assembly 4 to vibrate when the material storage assembly 4 is running. When vibration is required during the rusting and leaching process, the material storage assembly 4 enters the rusting tank 61 and the leaching tank 62 downwards. The push-pull bracket 662 on the attitude adjustment mechanism 46 abuts against the top of the push plate 53, and then the push unit 1 starts to reciprocate, driving the push-pull bracket 662 to move up and down. When the push-pull bracket 662 moves up and down, it drives the push-pull rod 463 to move, thereby driving the storage unit 45 connected to it to rotate up and down along the end of the transfer pipe 472. When the storage unit 45 rotates up and down, the raw material inside the storage unit 45 vibrates up and down, so that the reaction liquid in the rusting tank 61 and the leaching tank 62 quickly comes into contact with the raw material, quickly flushes the raw material, and improves the reaction efficiency and quality. During loading and unloading, the storage assembly 4 moves to the position of the conveying channel 25. The two sets of push-pull rods 474 on the opening and closing mechanism 47 on the storage assembly 4 move to the drive plate in the mounting groove 26 on the top holding channel 23 of the drive adjustment mechanism. When the push unit 2 is started, the drive plate moves vertically, and then the push-pull rods 474 move vertically. When the push-pull rods 474 move, the rotating tube 475 rotates under the action of the thread, and then the bevel gear 4 rotates. After that, under the action of the transfer unit 473, the transfer unit 477 rotates. Finally, the rotating shaft 3 on the transfer unit 477 drives the outer wall sealing plate 453 to deflect when it rotates. When the outer wall sealing plate 453 deflects, the opening and closing operation of the storage unit 45 is realized. During feeding, the outer wall sealing plate 453 is deflected upward so that the outer wall sealing plate 453 is in an upward cleaning state, which facilitates the input of raw materials. At this time, the push unit is started, pushing the feed pipe downward to the upper part of the deflected outer wall sealing plate 453, and then the raw materials are fed from the hopper into the storage unit 45. When feeding, the fourth pusher unit is activated, pushing the receiving trough to the bottom of the storage unit 45. Then, the outer wall sealing plate 453 deflects downward, causing the outer wall sealing plate 453 to tilt downward, opening the storage unit 45. The raw material is discharged from the end opening of the support plate 451. In order to completely discharge the raw material on the storage unit 45, the fifth pusher unit on the pusher plate 2 56 located on the top of the retaining plate 1 54 is activated, causing the pusher plate 2 56 to move. After receiving, the same steps as above are performed to adjust the tilt angle of the storage unit 45, so that the raw material in the storage unit 45 is completely discharged. This design simultaneously adjusts the tilt and opening / closing states of multiple storage units for raw materials during the feeding and unloading process, enabling rapid material delivery and unloading operations. This facilitates the feeding and unloading operations during the preparation of titanium-rich materials, improving feeding efficiency. It also achieves continuous feeding, etching, leaching, and unloading of raw materials in the reduction etching process for preparing titanium-rich materials. Simultaneously, the raw materials are agitated during etching and leaching, ensuring full contact between the materials and the reaction solution. This rapid rinsing of the raw materials by the reaction solution improves etching and leaching efficiency and quality, thereby enhancing the efficiency and quality of titanium-rich material preparation and reducing operational difficulty during the preparation process.
