Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a vanadium-containing shale acid-cooking reaction vessel. Background Technology
[0002] Acid maturation of vanadium-bearing shale is a method for extracting vanadium. Specifically, it involves mixing and maturing vanadium-bearing shale with acid to optimize vanadium leaching process parameters, improve vanadium leaching rate, and enhance product quality. The process begins with raw material processing: the vanadium-bearing shale is first coarsely crushed, then finely crushed to a particle size of less than 1.5 mm. A quartering method is then used to sample and analyze its main components. Next, acid maturation: the treated ore powder is mixed evenly with a certain amount of water and sulfuric acid, typically with 20% concentrated sulfuric acid, and then maturated at 140℃ for 3 hours. Therefore, a vanadium-bearing shale acid maturation reactor is required.
[0003] In existing vanadium-containing shale acid-mixing and ripening reactors, the stirring direction of the mixture of mineral powder, water, and sulfuric acid is always kept consistent during use, resulting in long stirring times and uneven mixing. To address these issues, we propose a new vanadium-containing shale acid-mixing and ripening reactor. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 An embodiment of this utility model provides a vanadium-containing shale acid-cooking reactor, comprising a reactor body 1, a feed inlet fixedly disposed at the top of the reactor body 1, a discharge outlet fixedly disposed at the bottom of the reactor body 1, valves disposed on both the feed inlet and the discharge outlet, an upper stirring shaft 2 rotatably disposed on the top of the inner side of the reactor body 1, a first stirring rod 3 fixedly disposed on the outer ring of the upper stirring shaft 2, a lower stirring shaft 8 rotatably disposed at the lower end of the upper stirring shaft 2 through an auxiliary component, and a second stirring rod 11 fixedly disposed on the outer ring of the lower stirring shaft 8.
[0028] Furthermore, a power assembly is provided on the vessel body 1. The power assembly includes a mounting plate, which is fixedly installed on the outer side wall of the vessel body 1. A motor 14 is fixedly installed on the top of the mounting plate. A third pulley is fixedly installed at one end of the upper stirring shaft 2 that extends out of the top of the vessel body 1. A fourth pulley is fixedly installed at the drive end of the motor 14. A second synchronous belt 15 is rotatably installed between the third pulley and the fourth pulley.
[0029] Vanadium-containing ore powder, water, and sulfuric acid are fed into the reactor body 1 through the feed inlet. The motor 14 is started, and the upper stirring shaft 2 is driven to rotate via the second synchronous belt 15. In addition, by installing auxiliary components, the upper stirring shaft 2 and the lower stirring shaft 8 rotate in opposite directions, thereby making the first stirring rod 3 and the second stirring rod 11 rotate in opposite directions. This avoids the mixing direction of the mixture always being consistent, making the mixture more uniformly mixed. This solves the problem that existing vanadium-containing shale acid-cooking reactors always maintain a consistent mixing direction, resulting in long mixing time and uneven mixing.
[0030] Specifically, the auxiliary components include a connecting seat 4, which is fixedly installed on the inner wall of the vessel body 1. A movable groove is fixedly installed inside the connecting seat 4. A first gear 5 is fixedly connected to one end of the upper stirring shaft 2 that extends movably into the movable groove. A second gear 6 is rotatably installed inside the movable groove. The second gear 6 and the first gear 5 mesh with each other. A first pulley 7 is fixedly installed at the lower end of the second gear 6. A lower stirring shaft 8 is rotatably installed at the bottom of the connecting seat 4. A second pulley 9 is fixedly connected to one end of the lower stirring shaft 8 that extends movably into the movable groove. A first synchronous belt 10 is rotatably installed between the first pulley 7 and the second pulley 9. The central axes of the vessel body 1, the upper stirring shaft 2, and the lower stirring shaft 8 are all on the same vertical line. After the second synchronous belt 15 drives the upper stirring shaft 2 to rotate, it drives the first gear 5 to rotate, which in turn drives the second gear 6 and the first pulley 7 to rotate. Through the installation of the first synchronous belt 10, the second pulley 9 and the lower stirring shaft 8 are driven to rotate, so that the rotation directions of the upper stirring shaft 2 and the lower stirring shaft 8 are opposite, and the first stirring rod 3 and the second stirring rod 11 stir the mixture in opposite directions.
[0031] Furthermore, three inclined rods 12 arranged in a ring are fixedly installed at the bottom of the inner side of the vessel body 1. A support platform 13 is fixedly connected between the three inclined rods 12. The lower end of the lower stirring shaft 8 is rotatably connected to the support platform 13. The inclined rods 12 and the support platform 13 support the bottom of the lower stirring shaft 8, ensuring the stability of the rotation of the lower stirring shaft 8.
[0032] Furthermore, a support platform 16 is fixedly installed on the outer ring of the vessel body 1. Support rods are fixedly installed at the four corners of the bottom of the support platform 16. A cleaning component is installed between the support platform 16 and the vessel body 1. The cleaning component includes a water tank 17, which is fixedly installed on the top of the support platform 16. A water pump is installed on the top of the water tank 17. The outlet of the water pump is connected to a water supply pipe 18. The other end of the water supply pipe 18 is rotatably connected to the top of the upper stirring shaft 2 through a sealed bearing. A conveying trough and a water hole 19 are fixedly installed inside the upper stirring shaft 2. A diversion plate 20 is fixedly installed on the outer ring of the upper stirring shaft 2. A water spray ball 21 is fixedly installed at the bottom of the diversion plate 20. Several spray holes are fixedly opened on the surface of the water spray ball 21. The water supply pipe 18, the conveying trough, the water hole 19, the diversion plate 20, the water spray ball 21 and the spray holes are interconnected. There are two water spray balls 21, which are symmetrically distributed about the center line of the diversion plate 20.
[0033] After the device is used up, the inside of the vessel 1 needs to be cleaned. At this time, the water pump is started, and the water in the water tank 17 passes through the water pipe 18, the conveying trough, the water hole 19, the diversion plate 20, the water spray ball 21 and the spray hole in sequence, and then sprays onto the inner wall of the vessel 1 to clean the inner wall of the vessel 1. At the same time, the motor 14 is started, which drives the upper stirring shaft 2, the diversion plate 20 and the water spray ball 21 to rotate, so that the water spray ball 21 sprays water evenly to clean the inner wall of the vessel 1, thereby improving the cleaning effect of the vessel 1.
[0034] Working principle: Vanadium-containing ore powder, water, and sulfuric acid are fed into the reactor body 1 through the feed inlet. The motor 14 is started, and the upper stirring shaft 2 rotates via the second synchronous belt 15, which in turn drives the first gear 5 to rotate, which in turn drives the second gear 6 and the first pulley 7 to rotate. Through the installation of the first synchronous belt 10, the second pulley 9 and the lower stirring shaft 8 rotate, thus causing the upper stirring shaft 2 and the lower stirring shaft 8 to rotate in opposite directions. This results in the first stirring rod 3 and the second stirring rod 11 stirring the mixture in opposite directions, preventing the mixture from being disturbed. The stirring direction is always consistent, making the mixture more even. After the device is used up, the finished product is discharged from the outlet. Then the water pump is started, and the water inside the water tank 17 passes through the water pipe 18, the conveying trough, the water hole 19, the diversion plate 20, the water spray ball 21 and the spray hole in sequence, and is sprayed onto the inner wall of the vessel 1 to clean the inner wall of the vessel 1. At the same time, the motor 14 is started, which drives the upper stirring shaft 2, the diversion plate 20 and the water spray ball 21 to rotate, so that the water spray ball 21 sprays water evenly to clean the inner wall of the vessel 1 and avoids cleaning dead corners.
[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
