Description

Technical Field

[0001] This utility model relates to the field of chemical industry technology, and in particular to an automatic catalyst extrusion device for laboratory use. Background Technology

[0002] A catalyst is a substance that can alter the rate of a chemical reaction without changing its own mass or chemical properties before and after the reaction. In the laboratory, catalysts are used to accelerate chemical reactions, allowing them to reach the desired effect in a shorter time, or enabling reactions that would otherwise be difficult to occur to proceed smoothly. This helps researchers study chemical reaction mechanisms more efficiently and explore new synthetic routes. An automated extrusion device is a device used to extrude catalyst raw materials or other materials requiring shaping into strips using specific molds. Its function is to precisely control the catalyst forming process, ensuring that the produced catalysts have a uniform shape and size. This is crucial for ensuring the stability and repeatability of catalyst performance and greatly improves the efficiency and quality of catalyst preparation in the laboratory.

[0003] The raw material storage and conveying assembly stores the catalyst raw materials to be processed and quantitatively conveys them to the extrusion area via devices such as screw propellers. The extrusion molding assembly includes a high-pressure extrusion cylinder that extrudes the raw materials through a specific die under pressure. The power and transmission assembly is typically powered by an electric motor, which transmits power to the extrusion components via belts, gears, and other transmission components to ensure stable and sufficient extrusion pressure. The control assembly is equipped with an operating panel and a programmable logic controller (PLC). The shape and size of the catalyst strips are customized, with common dies including round and trilobal shapes, determining the final product's specifications. These components work together to achieve efficient and precise extrusion of laboratory catalyst strips.

[0004] In existing technologies, some automatic catalyst extrusion devices require different sizes of extruded strips, necessitating the replacement of different molds. However, mold replacement is a cumbersome process, requiring machine shutdown and careful disassembly of the old mold and installation of the new mold by professionals using tools. This consumes a significant amount of time, reduces production efficiency, and increases production costs. Therefore, an automatic catalyst extrusion device for laboratory use is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic extrusion device for laboratory catalysts, which aims to improve the existing technology where different sizes of extrusion are required, and different molds need to be changed. The mold changing operation is relatively cumbersome, requiring the machine to be stopped and professional personnel to carefully disassemble the old mold and install the new mold with the help of tools. This consumes a lot of time, reduces production efficiency, and increases production costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the force bar moves to make the limiting block disengage from the fixed block.

Detailed Implementation

[0031] 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.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of an automatic catalyst extrusion device for laboratory use, comprising a base shell 1, which serves as the foundation and supports the entire device. An outer shell 2 is fixedly connected to the top of the base shell 1. A transmission pipe 3 is fixedly connected to the right side of the outer shell 2. Protective covers 4 are fixedly connected to both the front and rear sides of the transmission pipe 3. The outer shell 2 transports the catalyst, while the transmission pipe 3 receives the catalyst from inside the outer shell 2 for extrusion. The protective covers 4 protect the internal disassembly components and ensure their stability. A second pushing block 6 is slidably connected to the right side of the protective cover 4, receiving external force and moving within the protective cover 4. A fixing plate is fixedly connected to the inner wall of the second pushing block 6. 7. Fixed plate 7 separates the two limiting components. Telescopic rods 8 are fixedly connected to the upper and lower sides of fixed plate 7. Springs 9 are provided on the outside of telescopic rods 8. Connecting rods 10 are fixedly connected to the top of telescopic rods 8. Limiting blocks 11 are fixedly connected to the top of connecting rods 10. Both telescopic rods 8 and springs 9 receive the force of limiting blocks 11, thereby squeezing and applying force. Two fixed blocks 12 are fixedly connected to the inner wall of protective cover 4. Force rods 23 are slidably connected to the opposite side of the two fixed blocks 12. Fixed blocks 12 limit the limiting blocks 11 to make them stable. Force rods 23 apply force to the limiting blocks 11. A metering component for quantitative feeding is fixedly connected to the top of outer shell 2.

[0033] Reference Figure 2 and Figure 4The metering component includes a protective shell 16, the bottom of which is fixedly connected to the top of the outer shell 2. The protective shell 16 protects the internal metering component and stabilizes it. A motor 17 is fixedly connected to the rear side of the protective shell 16. A rotating rod is fixedly connected to the drive end of the motor 17. A rotating column 18 is fixedly connected to the outside of the rotating rod. Multiple metering plates 19 are fixedly connected to the outside of the rotating column 18. The motor 17 is the driving source of the metering component, which causes the rotating rod to rotate, causing the rotating column 19 to rotate with the rotating rod, and causing the metering plates 18 to rotate. The spacing between the two metering plates 19 allows for metering of the catalyst.

[0034] Reference Figures 1 to 3 Two connecting blocks 24 are fixedly connected to the opposite sides of the two bottom shells 1. Two force-applying blocks 25 are fixedly connected to the opposite sides of the two connecting blocks 24. Two fixing plates 3 26 are fixedly connected to the opposite sides of the two force-applying blocks 25. The fixing plates 3 26 receive external force, thereby applying force to the force-applying blocks 25, causing the connecting blocks 24 to move, which in turn moves the force-applying rod 23. A connecting block 13 is fixedly connected to the rear side of the pushing block 26. A guide plate is fixedly connected to the inner wall of the protective cover 4. A spring 2 15 is fixedly connected inside the guide plate. A force-applying block 14 is fixedly connected to the left side of the spring 2 15. The left side of the force-applying block 14 contacts the right side of the connecting block 13. The connecting block 13 moves with the pushing block 26. The guide plate allows the pushing block 26 and the force-applying block 14 to move linearly. The spring 19 receives the applied force. The force of the block moves the pusher. The bottom of the force rod 23 contacts the top of the limit block 11. The force rod 23 receives the pusher force from the connecting block 24, thus applying force to the limit block 11. The left side of the pusher block 26 is fixedly connected to the pusher block 15. The pusher block 15 receives external force, thus applying force to the limit block 11. The top of the bottom shell 1 is fixedly connected to the electric pusher plate 21. The drive end of the electric pusher plate 21 is fixedly connected to the pusher plate 22. The outer side of the pusher plate 22 is slidably connected to the inner wall of the outer shell 2. The electric pusher plate 21 receives the power from the pusher plate 22, thus squeezing the catalyst entering the outer shell 2 and making it enter the transmission pipe 3. The rear side of the protective shell 16 is fixedly connected to the fixing plate 20. The bottom of the motor 17 is fixedly connected to the top of the fixing plate 20. The fixing plate 20 provides stable power to the motor 17, making the motor 17 run stably.

[0035] Working principle: The operator holds the pusher block 5 to allow the pusher block 6 to enter the interior, causing the spring 15 to compress it. At this time, under the action of the spring 9 and the telescopic rod 8, the limiting block 11 is pushed into the limiting groove of the fixed block 12. When replacement is needed, the operator holds the fixed plate 26 to move the force application block 25, which causes the connecting block to drive the force application rod 23 to move, causing the limiting block 11 to disengage from the fixed block 12. Once the restriction is removed, the spring 15 begins to release its force, thereby pushing the pusher block out. This realizes the disassembly of the mold of the automatic extrusion device. In addition, different specifications of molds can be quickly replaced to meet the diverse needs of catalyst extrusion, thus significantly improving experimental efficiency.

[0036] Motor 17 drives the rotating rod to rotate, which in turn drives the rotating column 18 to rotate, causing the metering plate 19 outside the rotating column 18 to rotate as well. This allows the catalyst to be metered into the outer shell 2 under the action of the metering plate 19. Driven by the electric push plate 21, the push plate 22 pushes the catalyst into the transmission pipe 3, thereby realizing automatic feeding of the automatic extrusion device. In addition, the precise control of the amount of material added maintains the stability of the material supply during the extrusion process, thereby ensuring the uniformity of the catalyst product quality.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
