Technical Field

[0001] This invention relates to the field of alumina catalyst production technology, and more particularly to a production system for preparing alumina catalysts. Background Technology

[0002] In existing technologies, alumina catalysts, with alumina as the main component, are widely used in the catalytic processes of chemical reactions. They possess high specific surface area, chemical stability, and good thermal stability, thus serving as catalysts or catalyst supports in many industrial reactions. Due to their superior performance and broad application prospects, alumina catalysts remain an important research direction in catalysis research and industrial applications. With advancements in technology, it is believed that their application scope and performance will continue to improve. In existing technologies, the production of alumina catalysts often lacks material control, and the addition of large amounts of material can easily affect the mixing process. Therefore, this application proposes a production system for preparing alumina catalysts to solve the above-mentioned problems. Summary of the Invention

[0003] In view of the technical problem that the production of alumina catalysts often lacks material control and that the addition of large amounts of materials can easily affect the mixing process, this invention proposes a production system for preparing alumina catalysts.

[0004] The present invention discloses a production system for preparing alumina catalysts, comprising a base support, and further comprising: A material mixing box, which is fixedly connected to the top of the base support; An auxiliary frame is fixedly connected to the top of the material mixing box; A material box, which is fixedly connected to the top of the auxiliary frame and has its bottom penetrating through the auxiliary frame; A material control door is slidably connected to the front side of the auxiliary frame, and the material control door is engaged with the bottom of the material box; A movable frame, which is slidably connected within a base support; A material filter screen, which is fixedly connected inside the movable frame; A material conveying pipe is fixedly connected to the right side of the material mixing box; An auxiliary mechanism is provided on the left side of the material mixing box, and a matching mechanism is provided inside the base support.

[0005] Preferably, the auxiliary mechanism includes an electric rod, an L-shaped plate, and a contact wheel. The electric rod is fixedly connected to the left side of the material mixing box, the L-shaped plate is slidably connected to the left side of the material mixing box, and the top of the L-shaped plate is fixedly connected to the output end of the electric rod. The contact wheel is rotatably connected to the rear side of the L-shaped plate.

[0006] Furthermore, the design of the auxiliary mechanism, including the electric lever, L-shaped plate, and contact wheel, allows the material control door of the material box to be opened and closed flexibly. This flexibility not only enhances the accuracy of material delivery but also provides greater operational space for the subsequent mixing process. This design ensures that the amount of material delivered each time can be accurately controlled, thereby improving the uniformity of the mixing process and ultimately ensuring that the resulting catalyst has good performance and consistency.

[0007] Preferably, a sloping panel is fixedly connected to the bottom of the material control door, and the sloping surface of the sloping panel is in active contact with the contact wheel. A spring is fixedly connected to the top of the material control door, and one end of the spring is fixedly connected to the left side of the material box.

[0008] Furthermore, the sloping panel design at the bottom of the material control door, in effective coordination with the contact wheel, makes the opening process of the material control door smoother and improves the overall smoothness of the operation. On this basis, the spring can automatically return to its original position, avoiding problems such as material leakage or uneven mixing caused by operational errors. This design greatly improves the safety and reliability of the system, reduces the accidental risks that may occur during the production process, and also reduces the dependence on operators, optimizing the overall operation process.

[0009] Preferably, the mating mechanism includes a sliding frame, a contact frame, a material guide door, a pull plate, and a rack. The sliding frame is slidably connected to the outer wall of the base support, the contact frame is slidably connected to the outer wall of the sliding frame, the material guide door is slidably connected inside the base support, and the top of the material guide door extends into the material conveying pipe. The pull plate is rotatably connected to the front side of the material guide door, and the top of the pull plate is rotatably connected to the front side of the sliding frame. The rack is slidably connected to the right side of the base support, and the top of the rack is fixedly connected to the bottom of the material guide door.

[0010] Furthermore, the design of the mechanism, including the sliding frame and the contact frame, can effectively guide the mixed material smoothly into the material filter screen. This design not only improves the flowability and processing efficiency of the material, but also reduces material loss during the transportation process. This efficient flow mechanism can ensure that the mixed catalyst quickly enters the next processing stage, thereby speeding up the production pace and improving the overall production efficiency.

[0011] Preferably, an electric actuator is fixedly connected inside the sliding frame, and the output end of the electric actuator is fixedly connected to the top of the contact frame, and the contact frame is in movable contact with the bottom of the movable frame.

[0012] Furthermore, the electric actuator enables precise control of the contact frame, allowing the movable frame to move effectively. This precise control not only increases the vibration frequency of the material filter screen but also quickly removes impurities and optimizes the filtration effect. By improving filtration efficiency, the purity and quality of the final product are further ensured, laying a solid foundation for subsequent production processes.

[0013] Preferably, a control motor is fixedly connected to the inner right side of the base bracket, and the output shaft of the control motor passes through the base bracket and is fixedly connected to a gear, which meshes with a rack.

[0014] Furthermore, the design combining the control motor and rack enables efficient power transmission, ensuring the synchronous movement of the material guide gate and related components. This coordination greatly improves the efficiency of the entire production process, allowing each link to be closely connected, reducing production bottlenecks caused by mechanical failures or lags in movement, and improving the overall smoothness and continuity of production.

[0015] Preferably, a material drying box is fixedly connected to the right side of the base bracket, and the material drying box cooperates with the material filter screen.

[0016] Furthermore, the effective coordination between the material drying chamber and the material filter ensures that the filtered material can be dried in a timely manner. This design not only avoids the impact of moisture on subsequent production steps, but also helps to improve the purity and stability of the final product. By effectively controlling the humidity of the material, not only is the performance of the catalyst improved, but its reliability in subsequent applications is also ensured.

[0017] Preferably, a material stirring rod is fixedly connected to the top inner wall of the base support, and the top of the material stirring rod extends into the material mixing box.

[0018] Furthermore, the design of the material stirring rod enables it to provide a uniform stirring effect during the mixing process, ensuring good mixing between the bauxite material and the auxiliary catalyst. This uniform mixing process is directly related to the activity and performance of the catalyst, providing an important guarantee for the quality of the final product. Through a scientific and reasonable stirring design, the potential of the raw materials can be maximized, ensuring the high efficiency and durability of the catalyst in actual use.

[0019] The beneficial effects of this invention are: 1. In the production process of bauxite materials, the raw materials of bauxite need to be pre-set in the material box, and necessary auxiliary catalysts need to be added at the same time. This stage is crucial because it directly affects the subsequent mixing and processing effect. During the mixing process, the effective movement of the material control gate can be achieved by precisely controlling the operation of the electric rod. The cooperation between the electric push rod and the spring can produce a good mechanical linkage effect, which enables the material control gate to move cyclically. This design concept not only allows us to control the material to enter the material mixing box in batches, but also ensures the efficiency of the mixing process through this batch control method. Specifically, it avoids the phenomenon of agglomeration caused by a large amount of material rushing into the mixing box at the same time, thereby ensuring the smooth progress of the entire processing flow and the quality of the final product. 2. After the mixing process is completed, the next step is to control the operation of the motor to open the material guide gate. In this step, the effective operation of the motor ensures that the material guide gate opens precisely, allowing the mixed material to flow smoothly through the material delivery pipe to the surface of the material filter screen. In addition to controlling the opening and closing of the material guide gate, it is also necessary to precisely control the movement position of the contact frame to ensure that it is accurately positioned below the movable frame. Through the effective operation of the electric actuator, we can achieve vibration control of the material filter screen. This vibration not only helps to improve the efficiency of filtering impurities in the material, but also accelerates the removal speed of impurities, ensuring the rapid acquisition of high-quality materials. 3. After this series of steps, the filtered pure material will be guided into the material drying chamber for subsequent drying. The drying process is also an indispensable part of the production process. It helps to remove moisture from the material and ensures that the quality of the final alumina catalyst meets the standards. Through the coordinated operation of the above-mentioned links, the production process of alumina catalyst is finally completed, achieving the goal of efficient and high-quality production. The design and operation of the entire system not only reflects the advanced nature of modern production technology, but also provides a strong guarantee for the production of bauxite and catalysts.

[0020] By pre-setting bauxite material in the material box and adding an auxiliary catalyst, the material stirring rod can complete the mixing process during mixing. At the same time, the movement of the material is controlled in batches to ensure mixing efficiency and avoid agglomeration caused by a large amount of material entering the box, which would affect the processing. After mixing, the material filter screen is vibrated to quickly filter impurities in the material, improving the filtration efficiency. The filtered material is then dried in a material drying oven, thus completing the production of alumina catalyst. Attached Figure Description

[0025] Through the aforementioned mechanism, the production system for preparing alumina catalysts ensures the stability and structural integrity of the entire system during operation through the fixed connection between the base support 1 and the material mixing box 2. This design not only improves the equipment's shock resistance and reduces the impact of changes in the external environment, but also effectively improves production efficiency and product quality. Whether under high-intensity operation or long-term operation, the firm connection between the base support 1 and the material mixing box 2 ensures that the equipment always maintains its optimal working condition, thus providing a reliable guarantee for the uniform production of catalysts.

[0026] In this embodiment, the auxiliary mechanism includes an electric rod 7, an L-shaped plate 8, and a contact wheel 9. The electric rod 7 is fixedly connected to the left side of the material mixing box 2, the L-shaped plate 8 is slidably connected to the left side of the material mixing box 2, and the top of the L-shaped plate 8 is fixedly connected to the output end of the electric rod 7. The contact wheel 9 is rotatably connected to the rear side of the L-shaped plate 8. The design of the auxiliary mechanism, including the electric rod 7, the L-shaped plate 8, and the contact wheel 9, allows the material control door 5 of the material box 4 to be opened and closed flexibly. This flexibility not only enhances the accuracy of material feeding but also provides greater operating space for the subsequent mixing process. This design ensures that the amount of material fed each time can be accurately controlled, thereby improving the uniformity of the mixing process and ultimately ensuring that the catalyst produced has good performance and consistency.

[0027] In this embodiment, a sloping panel is fixedly connected to the bottom of the material control door 5, and the sloping surface of the sloping panel is in active contact with the contact wheel 9. A spring 6 is fixedly connected to the top of the material control door 5, and one end of the spring 6 is fixedly connected to the left side of the material box 4. The sloping panel design at the bottom of the material control door 5 and the effective cooperation with the contact wheel 9 make the opening process of the material control door 5 smoother and improve the smoothness of the entire operation. On this basis, the spring 6 can automatically return to its original position to avoid problems such as material leakage or uneven mixing caused by operational errors. This design greatly improves the safety and reliability of the system, reduces the accidental risks that may occur during the production process, and also reduces the dependence on operators and optimizes the overall operation process.

[0028] In this embodiment, the cooperating mechanism includes a sliding frame 19, a contact frame 21, a material guide door 12, a pull plate 18, and a rack 13. The sliding frame 19 is slidably connected to the outer wall of the base support 1, the contact frame 21 is slidably connected to the outer wall of the sliding frame 19, the material guide door 12 is slidably connected inside the base support 1, and the top of the material guide door 12 extends into the material conveying pipe 11. The pull plate 18 is rotatably connected to the front side of the material guide door 12, and the top of the pull plate 18 is rotatably connected to the front side of the sliding frame 19. The rack 13 is slidably connected to the right side of the base support 1, and the top of the rack 13 is fixedly connected to the bottom of the material guide door 12. The design of the cooperating mechanism, including the sliding frame 19 and the contact frame 21, can effectively guide the mixed material smoothly into the material filter screen 17. This design not only improves the flowability and processing efficiency of the material, but also reduces material loss during the conveying process. This efficient flow mechanism can ensure that the mixed catalyst quickly enters the next processing stage, thereby accelerating the production pace and improving the overall production efficiency.

[0029] In this embodiment, an electric actuator 20 is fixedly connected inside the sliding frame 19, and the output end of the electric actuator 20 is fixedly connected to the top of the contact frame 21. The contact frame 21 is in movable contact with the bottom of the movable frame 16. The electric actuator 20 enables precise control of the contact frame 21, thereby allowing the movable frame 16 to move effectively. This precise control not only improves the vibration frequency of the material filter screen 17, but also quickly removes impurities and optimizes the filtration effect. By improving the filtration efficiency, the purity and quality of the final product are further ensured, laying a solid foundation for subsequent production processes.

[0030] In this embodiment, a control motor 14 is fixedly connected to the inner right side of the base bracket 1, and the output shaft of the control motor 14 passes through the base bracket 1 and is fixedly connected to a gear 15. The gear 15 meshes with the rack 13. The design of the control motor 14 and the rack 13 together realizes efficient power transmission and ensures the synchronous movement of the material guide door 12 and related components. This coordination greatly improves the efficiency of the entire production process, enables each link to be closely connected, reduces production bottlenecks caused by mechanical failures or lag in action, and improves the overall smoothness and continuity of production.

[0031] In this embodiment, a material drying box 22 is fixedly connected to the right side of the base bracket 1, and the material drying box 22 cooperates with the material filter screen 17. The effective cooperation between the material drying box 22 and the material filter screen 17 ensures that the filtered material can be dried in a timely manner. This design not only avoids the impact of moisture on subsequent production steps, but also helps to improve the purity and stability of the final product. By effectively controlling the humidity of the material, not only is the performance of the catalyst improved, but its reliability in subsequent applications is also ensured.

[0032] In this embodiment, a material stirring rod 10 is fixedly connected to the top inner wall of the base support 1, and the top of the material stirring rod 10 extends into the material mixing box 2. The design of the material stirring rod 10 enables it to provide a uniform stirring effect during the mixing process, ensuring good mixing between bauxite material and auxiliary catalyst. This uniform mixing process is directly related to the activity and performance of the catalyst, providing an important guarantee for the quality of the final product. Through a scientific and reasonable stirring design, the potential of the raw materials can be maximized, ensuring the high efficiency and durability of the catalyst in actual use.

[0033] Working Principle: In actual operation, by pre-setting bauxite material in material box 4 and simultaneously adding the required auxiliary catalyst, the entire production process can proceed smoothly. In this stage, the electric lever 7 plays a key control role. Through its precise movement, it can effectively drive the L-shaped plate 8 to rise. As the L-shaped plate 8 moves continuously, it will drive the contact wheel 9 to move synchronously. This coordination allows the contact wheel 9 to cooperate with the inclined surface of the inclined plate, smoothly pushing the material control door 5 to move to the left. When the material control door 5 begins to move, it will open the material box 4, allowing the internal materials to flow out smoothly and guiding these materials into the material mixing box 2. In mixing chamber 2, the material stirring rod 10 is activated and begins to thoroughly stir the bauxite material and auxiliary catalyst, significantly improving the mixing effect. During this process, the output end of the electric rod 7 cooperates with the spring 6 to realize the left and right cyclical movement of the material control gate 5, ensuring that the material can enter the material mixing chamber 2 in batches. This design effectively avoids the mixing and agglomeration problem caused by a large amount of material entering at the same time, thereby ensuring processing efficiency and product quality. After the mixing process is completed, the next step is to operate by controlling the motor 14. The operation of the motor 14 directly affects the rotation of the gear 15, and the rotation of the gear 15 interacts with the rack 13 through its teeth, pushing the rack 13 downward. As the rack 13 moves synchronously, it pulls the material guide gate 12 open, allowing the mixed material to smoothly move through the material conveying pipe 11 to the surface of the material filter screen 17. Simultaneously, the movement of the material guide gate 12 also pulls the pull plate 18 to move synchronously. This process further causes the sliding frame 19 to move to the left. When the sliding frame 19 moves, it effectively controls the position of the contact frame 21, ensuring it moves accurately below the movable frame 16. During this process, the electric actuator 20 begins to function, controlling the rise of the contact frame 21, thereby driving the movable frame 16 to move. The output end of the electric actuator 20 also circulates during this process, ensuring the movable frame 16 can maintain its position. The system continues to move effectively to achieve vibration control of the material filter screen 17. This vibration not only facilitates the rapid filtration of impurities but also significantly improves the overall filtration efficiency. After this series of meticulous filtration processes, the pure material will be guided into the material drying chamber 22 for subsequent drying, completing the entire alumina catalyst production process. In summary, the entire system, through efficient design and precise control, not only achieves the manufacture of high-quality catalysts but also reflects the advanced nature and efficiency of modern production. The success of this process not only relies on the synergistic effect of various components but also represents the development and application of modern industrial automation technology, providing strong support for catalyst production.
