Description

Technical Field

[0001] The invention relates to the technical field of reactor charging, in particular to a reactor for chemical production which is convenient for charging. Background Art

[0002] Sulfuric acid leaching is a commonly used mineral extraction process, which is particularly suitable for the extraction of lithium from spodumene gravel. In the sulfuric acid leaching method, spodumene gravel and concentrated sulfuric acid are mixed in a reactor at a solid-liquid ratio of 1:3-5. Spodumene gravel is used as a raw material for extracting lithium. Spodumene gravel contains a high lithium content. Concentrated sulfuric acid is used as a leaching agent. Concentrated sulfuric acid can react chemically with the lithium element in spodumene gravel to extract it. In the sulfuric acid leaching method, the solid-liquid ratio is an important parameter. The solid-liquid ratio of 1:3-5 means that every 1 part of spodumene gravel requires 3-5 parts of concentrated sulfuric acid for leaching. This ratio is selected to ensure that the spodumene gravel can fully contact and react with the concentrated sulfuric acid. The reactor provides a closed, pressure-resistant, and corrosion-resistant environment for accommodating the mixture of spodumene gravel and concentrated sulfuric acid and reacting.

[0003] When adding spodumene gravel to the existing reactor, it is impossible to slow down the speed of adding spodumene gravel and control the feeding height of spodumene gravel. When spodumene gravel is quickly added to the reactor, the temperature, pressure and other parameters in the reaction system change rapidly, making the reaction violent. The violent reaction is not only difficult to control, but also causes damage to the reactor and its ancillary equipment. The rapid addition of materials leads to safety hazards such as material splashing and leakage, increasing the risk of injury to operators. At the same time, the violent reaction also causes serious accidents such as explosions. The too fast reaction speed leads to incomplete reaction or side reactions, thereby affecting the quality and performance of the final product. Summary of the invention

[0016] Beneficial Effects

[0017] The present invention has the following beneficial effects:

[0018] (1) The reaction kettle for chemical production that is easy to add materials uses a material blocking plate and a material flow port to block and discharge the conveying groove of the spiral conveying block, so that the spodumene crushed stone is intermittently loaded on the spiral conveying block, avoiding the spodumene crushed stone from being discharged from the conveying groove due to rapid rotation, thereby effectively slowing down the discharge speed of the spodumene crushed stone and realizing batch feeding of the spodumene crushed stone. It is also possible to realize intermittent feeding of the spodumene crushed stone, which is helpful to accurately adjust the addition rate of the spodumene crushed stone and avoid excessive reaction caused by adding too much at one time. The material blocking plate not only plays a role in blocking the spodumene crushed stone, but also effectively slows down the discharge speed of the spodumene crushed stone. The batch feeding also helps to better control the reaction temperature.

[0019] (2) The reaction kettle for chemical production is easy to add materials. The moving plate drives the feeding tank and the spiral conveying block to stably move up and down through the connecting column, so that the bottom end surface of the spiral conveying block moves to the top of the concentrated sulfuric acid liquid, so that the spodumene crushed stone is slowly added to the concentrated sulfuric acid from the spiral conveying block, avoiding the violent reaction between the spodumene crushed stone and the concentrated sulfuric acid due to the height being too high. The spiral conveying block allows the spodumene crushed stone to be slowly and evenly added to the concentrated sulfuric acid, thereby avoiding the occurrence of such violent reactions and preventing side reactions or product decomposition caused by excessive temperature, thereby improving product quality and yield.

[0020] (3) The reaction kettle for chemical production is easy to add materials. A counterweight block is installed inside the auxiliary scraper to facilitate the auxiliary scraper to return to its original position and to facilitate the movement of the spodumene crushed stone into the conveying groove. The synergistic effect of the main scraper and the auxiliary scraper ensures that the spodumene crushed stone can continuously and evenly fall onto the spiral conveying block, thereby improving the feeding efficiency. The spiral conveying block enables the spodumene crushed stone to be transported in an orderly manner along a specific path, thereby avoiding the problems of material accumulation and blockage. The main scraper and the auxiliary scraper are not only responsible for conveying the spodumene crushed stone, but also simultaneously clean the arc surface of the feed to prevent material residue and blockage.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0032] See also Figure 1-Figure 7 The embodiment of the present invention provides a technical solution: a reactor for chemical production that is easy to add materials, comprising a lithium carbonate reactor 1, a reaction chamber 2 opened inside the lithium carbonate reactor 1, a lifting and feeding assembly installed on the outer side of the lithium carbonate reactor 1, a feeding tank 9 installed on the outer surface of the lifting and feeding assembly, and a feeding pipe 10 installed on the top surface of the feeding tank 9;

[0033] The feeding tank 9 is provided with a feeding camber 11 inside, a spiral conveying block 27 is installed on the bottom surface of the feeding tank 9, a conveying groove 28 is provided inside the spiral conveying block 27, a movable groove 29 is provided inside the spiral conveying block 27, a toggle assembly is installed inside the feeding tank 9, a material control assembly is installed on the outer surface of the toggle assembly, the material control assembly includes a baffle plate 18 and a plurality of flow ports 23, the baffle plate 18 is installed on the outer surface of the toggle assembly, and a plurality of flow ports 23 are provided inside the baffle plate 18. The outer surface of the material baffle plate 18 is in active contact with the inner wall of the movable groove 29 at the material opening 23, and the connecting rod 17 drives the material baffle plate 18 to stably perform a reciprocating lifting and lowering motion, so that the material baffle plate 18 blocks and discharges the conveying groove 28 of the spiral conveying block 27, so that the spodumene crushed stone is intermittently loaded on the spiral conveying block 27, and the spodumene crushed stone is prevented from being discharged from the conveying groove 28 due to rapid rotation. The material baffle plate 18 drives a plurality of flow openings 23 to reciprocate, thereby effectively slowing down the spodumene crushed stone. The material speed is increased and the spodumene gravel is added in batches. The conveying groove 28 of the spiral conveying block 27 is blocked and discharged by the baffle plate 18 and the flow port 23 to realize intermittent feeding of the spodumene gravel, which is helpful to accurately adjust the addition rate of the spodumene gravel and avoid excessive one-time addition resulting in excessive reaction. The baffle plate 18 not only blocks the spodumene gravel, but also drives several flow ports 23 to perform similar actions through its reciprocating movement, effectively slowing down the feeding speed of the spodumene gravel, making the reaction process more stable, avoiding safety problems caused by rapid rotation of the feeding, and adding the spodumene gravel in batches, making the reaction more uniform and improving the reaction efficiency. At the same time, batch feeding also helps to better control the reaction temperature and avoid local overheating or uneven reaction. By accurately controlling the amount and speed of spodumene gravel, the risk in the reaction process can be reduced. This control method is particularly important when spodumene gravel reacts with highly corrosive substances such as concentrated sulfuric acid.

[0034] The lifting and feeding assembly includes a hydraulic press 3 and a movable plate 4. The hydraulic press 3 is installed on the outer surface of the lithium carbonate reactor 1, and the movable plate 4 is installed on the outer surface of the output end of the hydraulic press 3. The two end surfaces of the movable plate 4 are both installed with limit sliders 7. The inner surface of the lithium carbonate reactor 1 is installed with two limit slide rails 6. The outer surfaces of the two limit slide rails 6 correspond to the outer surfaces of the limit slide rails 7. The bottom surface of the movable plate 4 is evenly installed with connecting columns 8. The bottom surfaces of several connecting columns 8 are in active contact with the top surface of the feeding tank 9. The movable plate 4 drives the limit sliders 7 at both ends to move on the limit slide rails 6, so that the movable plate 4 drives the feeding tank 9 and the spiral conveying block 27 to stably lift through the connecting columns 8. The spiral conveying block 27 moves downward, so that the bottom surface of the spiral conveying block 27 moves above the concentrated sulfuric acid liquid, so that the spodumene crushed stone is slowly added to the concentrated sulfuric acid from the spiral conveying block 27, avoiding the violent reaction between the spodumene crushed stone and the concentrated sulfuric acid due to the height being too high. The spiral conveying block 27 allows the spodumene crushed stone to be slowly and evenly added to the concentrated sulfuric acid, thus avoiding the occurrence of such a violent reaction. The slow addition of the spodumene crushed stone is conducive to better controlling the reaction temperature and preventing side reactions or product decomposition caused by excessive temperature, thereby improving product quality and yield. The gas and heat generated by the violent reaction will cause impact and corrosion to the reactor and its ancillary equipment, and the spiral conveying block 27 can effectively reduce such impact and extend the service life of the equipment.

[0035] The toggle assembly includes a motor 12 and a reciprocating screw 13, the motor 12 is installed on the top surface of the feeding tank 9, the reciprocating screw 13 is installed on the outer surface of the output end of the motor 12, and the bottom surface of the reciprocating screw 13 is installed with a rotating shaft 14. Two limit columns 5 are installed inside the feeding tank 9, and a movable screw slider 16 is provided on the outer surface of the reciprocating screw 13. The inner surface of the screw slider 16 is in active contact with the outer surfaces of the two limit columns 5. A connecting rod 17 is installed on the outer surface of the screw slider 16. A moving groove 19 is provided inside the feeding tank 9, and the inner wall of the moving groove 19 is in active contact with the outer surface of the connecting rod 17. The connecting rod 17 One end surface is fixedly connected to the top surface of the baffle plate 18, and two limit columns 15 are installed inside the feeding tank 9. The outer surfaces of the two limit columns 15 are in active contact with the inner surface of the connecting rod 17. The reciprocating screw 13 and the screw slider 16 cooperate with each other. The screw slider 16 moves on the two limit columns 5, and the screw slider 16 drives the connecting rod 17 to move on the limit column 15. The connecting rod 17 moves stably in the moving groove 19, so that the connecting rod 17 drives the baffle plate 18 to stably perform reciprocating lifting and lowering movements back and forth, so that the baffle plate 18 blocks and discharges the conveying groove 28 of the spiral conveying block 27.

[0036] A stirring rod 20 is mounted on the outer surface of the rotating shaft 14, a main scraper 21 is mounted on the outer surface of the stirring rod 20, the outer surface of the main scraper 21 is in active contact with the outer surface of the feeding arc surface 11, a rotating column 24 is mounted inside the main scraper 21, an auxiliary scraper 22 is mounted on the outer surface of the rotating column 24, the outer surface of the auxiliary scraper 22 is in active contact with the outer surface of the feeding arc surface 11, a rubber protection block is mounted on one end surface of the auxiliary scraper 22, a counterweight block 26 is mounted inside the auxiliary scraper 22, and a counterweight block 26 is mounted inside the auxiliary scraper 22. The weight block 26 facilitates the auxiliary scraper 22 to return to its original position, so as to facilitate the movement of the spodumene crushed stone into the conveying groove 28. The synergistic effect of the main scraper 21 and the auxiliary scraper 22 ensures that the spodumene crushed stone can continuously and evenly fall onto the spiral conveying block 27, thereby improving the feeding efficiency. The spiral conveying block 27 enables the spodumene crushed stone to be transported in an orderly manner along a specific path, thus avoiding the problems of material accumulation and blockage. The main scraper 21 and the auxiliary scraper 22 are not only responsible for conveying the spodumene crushed stone, but also simultaneously clean the feed arc surface 11 to prevent material residue and blockage.

[0037] The working process of the present invention is as follows: when lithium carbonate needs to be prepared, spodumene crushed stone needs to be added into the lithium carbonate reactor 1. The hydraulic press 3 is first controlled by the controller to work, and the hydraulic press 3 drives the movable plate 4 to move downward, and the movable plate 4 drives the limit sliders 7 at both ends to move on the limit slide rails 6, so that the movable plate 4 drives the feeding tank 9 and the spiral conveying block 27 to stably move up and down through the connecting column 8, so that the bottom end surface of the spiral conveying block 27 moves to above the concentrated sulfuric acid liquid, so that the spodumene crushed stone is slowly added to the concentrated sulfuric acid from the spiral conveying block 27, and the spodumene crushed stone is prevented from reacting violently with the concentrated sulfuric acid due to the height being too high. The spiral conveying block 27 allows the spodumene crushed stone to be slowly and evenly added to the concentrated sulfuric acid, thereby avoiding the occurrence of such violent reaction. The slow addition of spodumene crushed stone is conducive to better controlling the reaction temperature, preventing side reactions or product decomposition caused by excessive temperature, thereby improving product quality and yield. The gas and heat generated by the violent reaction will cause impact and corrosion to the reactor and its ancillary equipment, and the spiral conveying block 27 can effectively reduce such impact and extend the service life of the equipment.

[0038] When the screw conveying block 27 moves above the concentrated sulfuric acid liquid level, the controller controls the motor 12 to work, and the motor 12 slowly drives the reciprocating screw 13 and the rotating shaft 14 to rotate. The reciprocating screw 13 cooperates with the screw slider 16, and the screw slider 16 moves on the two limit columns 1 5. The screw slider 16 drives the connecting rod 17 to limit the movement on the limit column 2 15, and the connecting rod 17 stably moves in the moving groove 19, so that the connecting rod 17 drives the baffle plate 18 to stably perform reciprocating lifting and lowering movements back and forth, so that the baffle plate 18 blocks and discharges the conveying groove 28 of the screw conveying block 27, so that the spodumene crushed stone is intermittently loaded on the screw conveying block 27, and the spodumene crushed stone is prevented from being discharged from the conveying groove 28 due to rapid rotation. The baffle plate 18 drives a plurality of flow ports 23 to reciprocate, thereby effectively slowing down the discharge speed of the spodumene crushed stone and realizing the feeding of the spodumene crushed stone in batches. The baffle plate 18 and the flow port 23 block and discharge the conveying groove 28 of the spiral conveying block 27, thereby realizing intermittent feeding of spodumene gravel, which helps to accurately adjust the addition rate of spodumene gravel and avoid excessive reaction caused by adding too much at one time. The baffle plate 18 not only blocks the spodumene gravel, but also drives several flow ports 23 to perform similar actions through its reciprocating movement, effectively slowing down the feeding speed of spodumene gravel, making the reaction process more stable, avoiding safety problems caused by rapid rotation of feeding, and realizing batch feeding of spodumene gravel, making the reaction more uniform and improving the reaction efficiency. At the same time, batch feeding also helps to better control the reaction temperature and avoid local overheating or uneven reaction. By accurately controlling the amount and speed of spodumene gravel added, the risk in the reaction process can be reduced. This control method is particularly important when spodumene gravel reacts with highly corrosive substances such as concentrated sulfuric acid.

[0039] The rotating shaft 14 synchronously and slowly drives the stirring rod 20 and the main scraper 21 to move, and the spodumene crushed stone is added through the feeding pipe 10, and the spodumene crushed stone falls onto the spiral conveying block 27 through the feeding arc surface 11. The main scraper 21 drives the auxiliary scraper 22 to clean and move the feeding arc surface 11 synchronously through the rotating column 24, and moves the spodumene crushed stone from the feeding arc surface 11 to the spiral conveying block 27. When the rubber block 25 collides with the connecting rod 17, the auxiliary scraper 22 drives the rotating column 24 to deflect the angle, and a counterweight is installed inside the auxiliary scraper 22. Block 26 can conveniently drive the auxiliary scraper 22 to return to its original position, so as to facilitate the movement of the spodumene crushed stone into the conveying groove 28. The synergistic effect of the main scraper 21 and the auxiliary scraper 22 can ensure that the spodumene crushed stone can continuously and evenly fall onto the spiral conveying block 27, thereby improving the feeding efficiency. The spiral conveying block 27 enables the spodumene crushed stone to be transported in an orderly manner along a specific path, thus avoiding the problems of material accumulation and blockage. The main scraper 21 and the auxiliary scraper 22 are not only responsible for conveying the spodumene crushed stone, but also simultaneously clean the feed arc surface 11 to prevent material residue and blockage.
