Description

Technical Field

[0001] The utility model relates to the technical field of ammonium molybdate preparation, and more specifically to an ammonium molybdate reaction kettle. Background Art

[0002] The ammonium molybdate reaction kettle is a device used for chemical reactions during the production of ammonium molybdate. Its main structure consists of two parts: a kettle body and a controller. The kettle body includes a reaction vessel, a stirrer and its drive system, a cooling device, a safety device, etc. The kettle cover is usually equipped with a pressure gauge, a bursting disc safety device, a vapor-liquid phase valve, a temperature sensor, etc., which are convenient for monitoring and controlling the reaction process. Through the interlayer of the reaction kettle, a constant-temperature hot or cooling medium is injected to heat or cool the materials in the kettle at a constant temperature, so that the reaction proceeds under the set temperature conditions. Stirring reactions can be carried out under normal pressure or negative pressure according to usage requirements, enabling the materials to be fully mixed and contacted, accelerating the reaction speed, improving the reaction efficiency, and at the same time controlling the evaporation and reflux of the reaction solution.

[0003] In a traditional ammonium molybdate reaction kettle, the stirring shaft is driven by a motor. The motor drives the stirring shaft to rotate axially around its own axis through a transmission device such as a coupling or a reducer. The stirring blades are directly fixed on the rotating shaft, and their shapes, angles, and positions are relatively fixed, only forming a specific material flow pattern. In the production of ammonium molybdate, different reaction stages have different requirements for the material flow mode. This way of directly fixing the stirring blades to the rotating shaft makes it difficult to achieve the best mixing effect during stirring. Taking the ammonia leaching stage as an example, it is necessary to make molybdenum oxide fully mixed and contacted with ammonia water to generate ammonium molybdate solution. However, due to the fixed characteristics of the stirring blades, the material flow is single, resulting in molybdenum oxide being easily deposited at the bottom of the reaction kettle and unable to fully react with ammonia water. Moreover, the single flow pattern has limited effect on heat transfer, which is not conducive to maintaining a uniform reaction temperature and affects the reaction efficiency and effect. Another example is the acid precipitation stage. Similarly, due to the problem of the stirring blades, it is difficult to quickly meet the fine requirements for material mixing and reaction conditions, affecting the crystallization of ammonium molybdate and the product quality. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an ammonium molybdate reaction kettle to solve the problems existing in the above background art.

[0005] The utility model provides the following technical solution: an ammonium molybdate reaction kettle, including a reaction kettle main body and a driving motor fixedly installed on the top of the reaction kettle main body. The output end of the driving motor is fixedly connected with a rotating rod, the end of the rotating rod is fixedly connected with a rotating shaft, a mixing component is installed on the outer surface of the rotating shaft, and an adjusting component is installed at the connection between the end of the rotating shaft and the inner wall of the reaction kettle main body. The adjusting component is installed at the end of the mixing component.

[0006] Further, the mixing component includes fixing plates fixedly connected to the surface of the rotating shaft at equal intervals. The outer surface of the fixing plate is rotatably connected with stirring blade plates. The outer surface of the rotating shaft is hermetically and slidably connected with a sliding column. A rotating groove is formed inside the sliding column. A connecting plate is rotatably connected to the inside of the rotating groove through a fixing pin. One end of the connecting plate away from the rotating groove is rotatably connected to the inside of the stirring blade plate. The inner center of the rotating shaft is rotatably connected with a reciprocating lead screw through a bearing. A movable tube is sleeved on the outer surface of the reciprocating lead screw. A convex block is fixedly connected to the inner wall of the movable tube. The surface of the convex block is inserted into the thread groove on the surface of the reciprocating lead screw. Connecting columns are fixedly connected to both side surfaces of the movable tube. A sealing ring is fixedly installed at the inner bottom end of the rotating shaft. The inner wall of the sealing ring is hermetically connected to the outer surface of the reciprocating lead screw. Limiting grooves are formed at equal intervals inside the rotating shaft.

[0007] Further, the adjusting component includes a toothed ring fixedly sleeved on the bottom end of the outer surface of the reciprocating lead screw. A fixing rod is fixedly connected to the inner wall of the reaction kettle body. A toothed plate is horizontally slidably connected inside the fixing rod. A rotating disc is rotatably connected to the inside of the toothed plate. A bolt is fixedly connected to the surface of the rotating disc. The outer surface of the bolt is threadedly connected to the inside of the fixing rod. A rotating groove is formed on the outer surface of the reaction kettle body. One end of the bolt away from the rotating disc extends into the rotating groove.

[0008] Further, the surface of the reciprocating lead screw is provided with threads at equal intervals in segments, and the number of segments matches the number of movable tubes. The movable tubes are longitudinally slidably connected to the inner center of the rotating shaft.

[0009] Further, the outer surface of the connecting column is longitudinally slidably connected to the inside of the limiting groove. The surface of the connecting column away from the movable tube extends to the outer surface of the rotating shaft. A rubber sealing sleeve is fixedly connected to the inner wall of the sliding column. The inner wall of the rubber sealing sleeve is longitudinally hermetically slidably connected to the outer surface of the rotating shaft.

[0010] Further, the depth of the limiting groove is less than the height of the rubber sealing sleeve. When the connecting column slides to the inner bottom end of the limiting groove, the top end of the inner wall of the rubber sealing sleeve is located above the limiting groove, that is, the sliding column is hermetically attached to the outer surface of the rotating shaft through the rubber sealing sleeve.

[0011] Further, the surface of the toothed plate close to the toothed ring is arc-shaped. The surface of the toothed plate is meshed with the surface of the toothed ring. The toothed ring is rotatably connected to the inner center of the fixing rod.

[0012] Further, a rectangular groove matching the toothed plate is formed inside the fixing rod. The outer surface of the toothed plate is horizontally slidably connected inside the rectangular groove. One end of the bolt close to the rotating disc extends into the toothed plate and is rotatably connected to the inside of the toothed plate.

[0013] Technical effects and advantages of the present utility model:

[0014] 1. In the present utility model, when the driving motor drives the rotating shaft to rotate, the movable pipe slides up and down while rotating due to the cooperation between the convex block and the thread of the reciprocating lead screw, thereby driving the sliding column and the stirring blade plate to move. The stirring blade plate can not only rotate axially along with the rotating shaft, but also rotate up and down around the fixed plate. This compound movement mode makes the materials in the reaction kettle mix more fully. In the ammonia leaching stage of ammonium molybdate production, it can effectively prevent molybdenum oxide from accumulating at the bottom, enabling it to come into full contact with ammonia water for reaction, greatly improving the reaction efficiency, reducing the reaction time and raw material waste.

[0015] 2. The present utility model realizes the adjustment of the stirring angle to meet different reaction requirements. The adjustment component endows the stirring blade plate with the function of angle adjustment. When a specific angle of stirring is required, the toothed plate is disengaged from the toothed ring by rotating the bolt. At this time, the reciprocating lead screw can rotate along with the rotating shaft, and the movable pipe is relatively fixed to the reciprocating lead screw, and the angle of the stirring blade plate is locked. In the acid precipitation stage, according to the fine requirements for material mixing and reaction conditions, the angle of the stirring blade plate can be flexibly adjusted to optimize the crystallization process of ammonium molybdate and improve the product quality, enhancing the adaptability of the reaction kettle to different reaction stages.

Specific embodiments

[0025] The present utility model will be further described below in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the accompanying drawings is for better explanation. The structure of the present utility model necessarily goes beyond these limited embodiments. For some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of this application.

[0026] Figures 1-8 This is the best embodiment of the present utility model. The following will Figures 1-8 further describe the present utility model in conjunction with the attached

[0027] An ammonium molybdate reactor includes a reactor main body 1 and a driving motor 2 fixedly installed on the top of the reactor main body 1. The output end of the driving motor 2 is fixedly connected to a rotating rod 3. The end of the rotating rod 3 is fixedly connected to a rotating shaft 5. A mixing assembly 4 is installed on the outer surface of the rotating shaft 5. An adjusting assembly 6 is installed at the connection between the end of the rotating shaft 5 and the inner wall of the reactor main body 1. The adjusting assembly 6 is installed at the end of the mixing assembly 4.

[0028] In this embodiment, the driving motor 2 provides power, drives the rotating shaft 5 to rotate through the rotating rod 3, provides a power basis for the operation of the mixing assembly 4 and the adjusting assembly 6. The mixing assembly 4 and the adjusting assembly 6 cooperate with each other to meet the reaction requirements at different stages of ammonium molybdate production, enhance the practicability and adaptability of the reactor, and effectively improve the production efficiency and product quality of ammonium molybdate.

[0029] Specifically, the mixing component 4 includes a fixing plate 41 fixedly connected to the surface of the rotating shaft 5 at equal intervals. A stirring blade plate 42 is rotatably connected to the outer surface of the fixing plate 41. A sliding column 44 is hermetically slidably connected to the outer surface of the rotating shaft 5. A rotating groove 45 is provided inside the sliding column 44. A connecting plate 43 is rotatably connected to the inside of the rotating groove 45 through a fixing pin. One end of the connecting plate 43 away from the rotating groove 45 is rotatably connected to the inside of the stirring blade plate 42. A reciprocating lead screw 46 is rotatably connected to the center of the inside of the rotating shaft 5 through a bearing. A movable tube 47 is sleeved on the outer surface of the reciprocating lead screw 46. The reciprocating lead screw 46 is rotatably connected to the center of the inside of the movable tube 47. A convex block 471 is fixedly connected to the inner wall of the movable tube 47. The surface of the convex block 471 is inserted into the thread groove on the surface of the reciprocating lead screw 46. Connecting columns 48 are fixedly connected to both side surfaces of the movable tube 47. A sealing ring 49 is fixedly installed at the bottom end of the inside of the rotating shaft 5. The inner wall of the sealing ring 49 is hermetically connected to the outer surface of the reciprocating lead screw 46. The outer surface of the reciprocating lead screw 46 is hermetically rotatably connected to the inner wall of the sealing ring 49. Limiting grooves 410 are provided at equal intervals inside the rotating shaft 5.

[0030] In this embodiment, the fixing plates 41 are fixedly arranged on the surface of the rotating shaft 5 at equal intervals, providing a support point for the stirring blade plates 42 so that they can rotate stably. The stirring blade plates 42 can rotate around the fixing plates 41, and in cooperation with the axial rotation of the rotating shaft 5, the stirring range is expanded, making the material mixing more uniform. The sliding column 44 is hermetically slidably connected to the rotating shaft 5, which can prevent materials from entering the limiting grooves 410 and causing corrosion damage to the rotating parts.

[0031] The convex block 471 on the inner wall of the movable tube 47 is inserted into the thread groove of the reciprocating lead screw 46. When the rotating shaft 5 rotates, the movable tube 47 rotates and slides up and down at the same time, thereby driving the stirring blade plate 42 to achieve a composite movement of axial rotation and up-and-down rotation. This movement mode can enable molybdenum oxide to fully contact with ammonia water during the ammonia leaching stage, improve the reaction efficiency, and reduce raw material waste.

[0032] The sealing ring 49 is hermetically connected to the outer surface of the reciprocating lead screw 46 to prevent materials from entering the inside of the rotating shaft 5 and ensure the normal operation of the equipment. The cooperation of the limiting grooves 410 and the connecting columns 48 restricts the movement track of the movable tube 47, ensures its stable up-and-down sliding, and at the same time makes the movement of the sliding column 44 and the stirring blade plate 42 more stable and reliable.

[0033] Specifically, the adjusting component 6 includes a toothed ring 61 fixedly sleeved on the bottom end of the outer surface of the reciprocating lead screw 46. A fixed rod 62 is fixedly connected to the inner wall of the reaction kettle main body 1. A toothed plate 63 is horizontally slidably connected to the inside of the fixed rod 62. A turntable 64 is rotatably connected to the inside of the toothed plate 63. A bolt 65 is fixedly connected to the surface of the turntable 64. The outer surface of the bolt 65 is threadedly connected to the inside of the fixed rod 62. A rotating groove 101 is provided on the outer surface of the reaction kettle main body 1. One end of the bolt 65 away from the turntable 64 extends into the inside of the rotating groove 101.

[0034] In this embodiment, the toothed ring 61 is fixedly sleeved on the outer surface of the bottom end of the reciprocating lead screw 46, and can limit the rotation of the reciprocating lead screw 46 when meshing with the toothed plate 63. When the angle of the stirring vane 42 needs to be adjusted, the bolt 65 is rotated. The bolt 65 drives the toothed plate 63 to slide through the turntable 64, so that the toothed plate 63 disengages from the toothed ring 61. At this time, the reciprocating lead screw 46 can rotate with the rotating shaft 5, and the movable pipe 47 is relatively fixed to the reciprocating lead screw 46, thereby locking the angle of the stirring vane 42. In the acid precipitation stage, according to the fine requirements for the material mixing and reaction conditions, the angle of the stirring vane 42 can be flexibly adjusted to optimize the ammonium molybdate crystallization process and improve the product quality. The rotating groove 101 facilitates the operator to rotate the bolt 65 through an external tool, and the operation is simple and convenient.

[0035] Specifically, the surface of the reciprocating lead screw 46 is provided with threads at equal intervals in segments, and the number of segments matches the number of movable pipes 47. The movable pipes 47 are longitudinally slidably connected to the inner center of the rotating shaft 5.

[0036] In this embodiment, this setting enables all the movable pipes 47 to slide up and down and rotate stably on the reciprocating lead screw 46, ensuring that all the stirring vanes 42 move synchronously. The threaded design with equal intervals in segments ensures that the movement laws of the movable pipes 47 at different positions are consistent, making the stirring effect more uniform and stable, and improving the consistency and reliability of the reaction.

[0037] Specifically, the outer surface of the connecting column 48 is longitudinally slidably connected to the inside of the limiting groove 410. The surface of the connecting column 48 away from the movable pipe 47 extends to the outer surface of the rotating shaft 5. A rubber sealing sleeve 411 is fixedly connected to the inner wall of the sliding column 44, and the inner wall of the rubber sealing sleeve 411 is longitudinally and sealingly slidably connected to the outer surface of the rotating shaft 5.

[0038] In this embodiment, the connecting column 48 slides in the limiting groove 410 to ensure the accurate movement direction of the movable pipe 47, prevent it from deviating, and ensure the stable movement of the stirring vane 42. The rubber sealing sleeve 411 plays a sealing role to prevent materials and external impurities from entering the inside of the rotating shaft 5, protect the internal structure of the equipment, and extend the service life of the equipment.

[0039] Specifically, the depth of the limiting groove 410 is less than the height of the rubber sealing sleeve 411, and when the connecting column 48 slides to the bottom end inside the limiting groove 410, the top end of the inner wall of the rubber sealing sleeve 411 is located above the limiting groove 410, that is, the sliding column 44 is sealingly attached to the outer surface of the rotating shaft 5 through the rubber sealing sleeve 411.

[0040] In this embodiment, this design further ensures the sealing effect. Even when the connecting column 48 moves to the bottom of the limiting groove 410, the rubber sealing sleeve 411 can still effectively seal the rotating shaft 5, preventing material leakage and impurity entry. At the same time, it also avoids damage to the rubber sealing sleeve 411 by the limiting groove 410, ensuring the sealing performance and stability of the equipment and guaranteeing the long-term stable operation of the equipment.

[0041] Specifically, the surface of the tooth plate 63 close to the tooth ring 61 is arc-shaped. The surface of the tooth plate 63 is meshed and connected to the surface of the tooth ring 61. The tooth ring 61 is rotatably connected to the inner center of the fixed rod 62.

[0042] In this embodiment, the arc-shaped design makes the meshing of the tooth plate 63 and the tooth ring 61 closer and more stable. When adjusting the angle of the stirring blade 42, it can more precisely control the meshing and disengagement of the tooth plate 63 and the tooth ring 61, ensuring the accuracy and reliability of the angle adjustment, and further ensuring the stability of the angle locking of the stirring blade 42 to meet the requirements of the stirring angle in different reaction stages.

[0043] Specifically, a rectangular groove matching the tooth plate 63 is opened inside the fixed rod 62. The outer surface of the tooth plate 63 is horizontally slidably connected inside the rectangular groove. One end of the bolt 65 close to the turntable 64 extends into the tooth plate 63 and is rotatably connected inside the tooth plate 63.

[0044] In this embodiment, the rectangular groove provides a stable sliding track for the tooth plate 63, enabling it to accurately slide horizontally under the drive of the bolt 65 to achieve meshing and disengagement with the tooth ring 61. The bolt 65 is rotatably connected to the tooth plate 63, facilitating the operator to adjust the position of the tooth plate 63 by rotating the bolt 65. The operation is simple and convenient, improving the efficiency and convenience of angle adjustment.

[0045] The working principle and usage process of the present utility model: When in use, after the material is placed into the reaction kettle main body 1 through the feeding port at the top of the reaction kettle main body 1, by starting the driving motor 2, the driving motor 2 drives the rotating shaft 5 to rotate through the rotating rod 3. Since the tooth ring 61 is meshed by the tooth plate 63, the tooth ring 61 and the reciprocating lead screw 46 cannot rotate. When the rotating shaft 5 rotates, the movable tube 47 rotates on the outer surface of the reciprocating lead screw 46 through the connecting column 48. Through the meshing of the convex block 471 and the thread on the surface of the reciprocating lead screw 46, the movable tube 47 slides up and down on the surface of the reciprocating lead screw 46. When the movable tube 47 slides up and down, the sliding column 44 is driven to slide up and down through the connecting column 48, and through the rotation of the connecting plate 43, the stirring blade 42 is driven to swing up and down. At this time, while the stirring blade 42 rotates axially inside the reaction kettle main body 1, it rotates up and down around the fixed plate 41, enabling the materials inside the reaction kettle main body 1 to be quickly mixed, improving the reaction efficiency;

[0046] When it is necessary to fix the angle of the stirring blade 42, observe the angle of the stirring blade 42 through the charging port at the top of the reactor body 1, and at the same time rotate the rotating shaft 5. When the stirring blade 42 is adjusted to the appropriate angle, stop rotating the rotating shaft 5, and then rotate the bolt 65 clockwise with a wrench. The bolt 65 drives the toothed plate 63 to slide to the right through the turntable 64. At this time, the toothed plate 63 slides away from the toothed ring 61. When the toothed plate 63 is no longer engaged with the toothed ring 61, when the rotating shaft 5 rotates, the reciprocating lead screw 46 rotates following the rotating shaft 5 through the toothed ring 61. Therefore, the reciprocating lead screw 46 and the movable pipe 47 are relatively fixed, thus preventing the convex block 471 from meshing and rotating on the reciprocating lead screw 46. Therefore, the angle of the stirring blade 42 is positioned.

[0047] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
