Description

Technical Field

[0001] This utility model belongs to the field of chemical production, and specifically relates to a multi-layer stirrer for the production of hydrated catalysts. Background Technology

[0002] In the field of chemical production, hydration catalysts are key materials for promoting efficient hydration reactions. Their production process places extremely high demands on the uniformity of material mixing, reaction efficiency, and product purity. Stirring, as the core link in material mixing, mass transfer, and reaction in the production of hydration catalysts, directly affects the activity, selectivity, and stability of the catalyst.

[0003] Traditional hydration catalyst production typically employs single-tank mixing equipment, using a single agitator (such as a slanted blade, ribbon blade, or anchor blade) to mix the materials. This monotonous mixing method and fixed blade type make it difficult to adapt to the changing properties of the materials at different reaction stages. For example, in the initial stage of the reaction, strong shear forces are required for rapid dispersion; in the middle stage, high rotation speeds are needed for thorough mixing; and in the later stage, gentle stirring is necessary to avoid excessive shearing that could damage the established catalyst structure. Therefore, single-tank mixing equipment cannot meet these dynamic demands, resulting in poor mixing and affecting the quality of the hydration catalyst.

[0004] Therefore, we propose a multi-layer stirrer for the production of hydrated catalysts to solve the above problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 1 This utility model provides a technical solution for a multi-layer stirrer used in the production of hydrated catalysts: Example 1: according to Figure 1 As shown, it includes a back plate 22, a primary mixing tank 4, a secondary mixing tank 5, a tertiary mixing tank 6, a drive motor 3, a transmission assembly 1, and a transmission assembly 2. The upper and lower ends of the back plate 22 are respectively fixedly connected to a top plate 21 and a base 1. Three sets of support seats 24 are fixedly installed on its front side. Side plates 23 are welded and fixed to the left and right sides of the back plate 22, and the side plates 23 are welded and fixed between the top plate 21 and the base 1.

[0019] The primary mixing tank 4, the secondary mixing tank 5, and the tertiary mixing tank 6 are respectively fixedly installed on three sets of support seats 24. The top of the primary mixing tank 4 is equipped with a bearing 1, and the primary mixing shaft 42 is installed inside the bearing 1. The bottom end of the primary mixing shaft 42 extends into the tank body of the primary mixing tank 4 and is fixedly installed with inclined blades. The top of the primary mixing tank 4 is equipped with a primary feed pipe 41, which is connected to multiple feed pipes 11.

[0020] The drive motor 3 is fixedly installed on the upper surface of the top plate 21. Its output shaft passes through the top plate 21 and is connected to the top of the primary stirring shaft 42. By starting the drive motor 3, the drive motor 3 drives the primary stirring shaft 42 and the inclined blade to rotate, providing strong shear force in the early stage of the reaction and realizing rapid dispersion of materials.

[0021] The top of the secondary mixing tank 5 is equipped with a bearing 2, and a secondary mixing shaft 51 is installed inside the bearing 2. The bottom end of the secondary mixing shaft 51 extends into the tank body of the secondary mixing tank 5 and is fixedly installed with a spiral blade. The top of the secondary mixing tank 5 is equipped with a secondary feed pipe 52 and a speed-increasing gearbox 53. The output shaft of the speed-increasing gearbox 53 is connected to the top end of the secondary mixing shaft 51, and its input shaft is equipped with a connecting shaft 54.

[0022] The transmission assembly includes two synchronous pulleys 82, which are respectively mounted on the primary stirring shaft 42 and the connecting shaft 54. The two synchronous pulleys 82 are connected by a synchronous belt 81. When the primary stirring shaft 42 rotates, the connecting shaft 54 ​​rotates synchronously through the cooperation of the synchronous pulleys 82 and the synchronous belt 81. After being accelerated by the speed-increasing gearbox 53, the secondary stirring shaft 51 and the ribbon impeller rotate at high speed to fully mix the materials and meet the mixing requirements in the middle stage of the reaction.

[0023] The top of the three-stage mixing tank 6 is equipped with a bearing 3, and a three-stage mixing shaft 61 is installed inside the bearing 3. The bottom end of the three-stage mixing shaft 61 extends into the tank body of the three-stage mixing tank 6 and is fixedly installed with an anchor-type impeller. The transmission assembly 2 includes two synchronous pulleys 91, which are respectively mounted on the connecting shaft 54 ​​and the three-stage mixing shaft 61. The two synchronous pulleys 91 are connected by a synchronous belt 92. When the connecting shaft 54 ​​rotates, the three-stage mixing shaft 61 rotates synchronously through the cooperation of the synchronous pulleys 91 and the synchronous belt 92. The anchor-type impeller gently stirs the material, avoiding excessive shearing and damage to the formed catalyst structure in the later stage of the reaction, thereby significantly improving the uniformity of the material and the reaction efficiency. The top of the three-stage mixing tank 6 is equipped with a three-stage feed pipe 62.

[0024] Multiple bearing seats 10 are respectively fitted on the upper sections of the connecting shaft 54 ​​and the three-stage stirring shaft 61. The bearing seats 10 are fixedly installed on the front side of the back plate 22, which effectively enhances the stability of the connecting shaft 54 ​​and the three-stage stirring shaft 61 during operation.

[0025] The bottom discharge pipe of the primary mixing tank 4 is connected to the secondary feed pipe 52, and the bottom discharge pipe of the secondary mixing tank 5 is connected to the tertiary feed pipe 62. Through the sequential connection of the primary mixing tank 4, the secondary mixing tank 5, and the tertiary mixing tank 6 via pipelines, the material can be mixed in three stages layer by layer to improve the mixing effect. Furthermore, after the material enters the next stage, new material can be added to continue mixing, enabling continuous production and improving production efficiency.

[0026] Manual valves 13 are installed on the secondary feed pipe 52 and the tertiary feed pipe 62 respectively. The right ends of the secondary feed pipe 52 and the tertiary feed pipe 62 are used to connect to the feeding pipeline. By connecting the feeding pipeline to the right ends of the secondary feed pipe 52 and the tertiary feed pipe 62, and opening the corresponding manual valves 13, it is convenient to replenish the required materials at different stages.

[0027] Solenoid valves 7 are installed on the bottom discharge pipes of the primary mixing tank 4, the secondary mixing tank 5, and the tertiary mixing tank 6, respectively. By opening the corresponding solenoid valves 7, the material is discharged through the discharge pipes.

[0028] In practical use, the multi-layer agitator of this utility model for the production of hydration catalysts first feeds material into the first-stage feed pipe 41 through multiple feed pipes 11. The material enters the first-stage mixing tank 4 through the first-stage feed pipe 41. Then, the drive motor 3 is started to drive the first-stage mixing shaft 42 and the inclined blades to rotate, so that the material is quickly dispersed. After mixing for a certain period of time, the solenoid valve 7 at the bottom of the first-stage mixing tank 4 is opened, so that the material flows into the second-stage mixing tank 5 through the second-stage feed pipe 52. Meanwhile, when the primary stirring shaft 42 rotates, the connecting shaft 54 ​​rotates synchronously through the cooperation of the synchronous pulley 82 and the synchronous belt 81. After being accelerated by the speed-increasing gearbox 53, it drives the secondary stirring shaft 51 and the screw belt blade to rotate at high speed, so as to fully mix the material. If it is necessary to add material during the stirring process, the corresponding hand valve 13 can be opened and the material can be added through the secondary feed pipe 52. After stirring for a certain period of time, the solenoid valve 7 at the bottom of the secondary mixing tank 5 is opened so that the material flows into the tertiary mixing tank 6 through the tertiary feed pipe 62. When the connecting shaft 54 ​​rotates, the three-stage mixing shaft 61 rotates synchronously through the cooperation of the synchronous pulley 91 and the synchronous belt 92. The anchor blades gently mix the material. If it is necessary to add material during the mixing process, the corresponding hand valve 13 can be opened and the material can be added through the three-stage feed pipe 62. After the final mixing is complete, open the solenoid valve 7 at the bottom of the three-stage mixing tank 6 to discharge the finished product.
