Description

Technical Field

[0001] This utility model relates to the field of feeding devices, and in particular to a feeding device for pharmaceutical intermediates used in the synthesis of chemical drugs. Background Technology

[0002] In the field of chemical pharmaceutical synthesis, the feeding device for pharmaceutical intermediates serves as a crucial link between raw material supply and reaction processes, and its performance directly impacts the efficiency and quality of drug production. With the pharmaceutical industry's ever-increasing demands for drug purity and production safety, the development of efficient, stable, and precise feeding devices has become an important direction for technological innovation in the industry. These devices must ensure continuous material transport while adapting to the harsh environments of different synthetic processes; their technological iteration is of great significance for promoting the high-quality development of the pharmaceutical industry.

[0003] Currently, most pharmaceutical intermediate feeding devices on the market adopt a combination of a mobile base and a conveying pipeline. The mobile base is usually equipped with casters or a sliding rail structure to facilitate flexible movement and layout adjustment of the device within the production workshop; the conveying pipeline achieves quantitative material conveying through methods such as spiral propulsion and negative pressure adsorption. These devices are designed with ease of operation and material transfer efficiency in mind, using an automated control system to adjust the feeding speed and batch size to meet the needs of different production lines.

[0004] However, existing feeding devices have significant drawbacks in practical applications. During production, the devices are highly susceptible to displacement due to accidental external impacts, strong airflow disturbances within the workshop, or tilting caused by uneven ground. Once the device's position shifts, the docking accuracy of the material conveying pipelines is affected, not only reducing feeding efficiency but also causing problems such as incomplete chemical reactions due to material spillage or obstructed conveying. This seriously affects the stability of pharmaceutical intermediate synthesis and the quality of the finished product. Therefore, a pharmaceutical intermediate feeding device for chemical drug synthesis is proposed to solve the above problems. Utility Model Content

A fixing component is provided on the outer wall of each slider 7. Each fixing component includes a locking post 9, one end of which engages with the inside of the slider 7. Each of the 9 pins is slidably connected to the inner wall of the connecting shell 8. The locking pins 9 engage with the slider 7 to fix the position of the slider 7. Each locking pin 9 has a pull ring 10 fixedly connected to one end. The pull ring 10 is used to pull the locking pin 9 to release the slider 7. Each locking pin 9 has a connecting ring 11 fixedly connected to the outer wall. Each connecting ring 11 is slidably connected to the inner wall of the connecting shell 8.

[0036] Reference Figure 4 and Figure 5The quantitative component includes a fixed cylinder 14, a height detection sensor 15, and multiple baffles 27. The top of the fixed cylinder 14 is fixedly connected to the bottom of the connecting pipe 4, and the bottom of the height detection sensor 15 is fixedly connected to the top of the fixed cylinder 14. The height detection sensor 15 is used to detect the height of the material, achieving precise control of the feeding amount. A fixed plate 16 is fixedly connected to one side of the fixed cylinder 14, and one side of the fixed plate 16 is fixedly connected to the outer wall of the spiral feeding pipe 3. The fixed plate 16 is used to support the fixed cylinder 14 and enhance the structural stability. A fixed block 18 and multiple fixed frames 17 are fixedly connected to the outer wall of the fixed cylinder 14. An electric telescopic rod 19 is fixedly connected inside the fixed block 18, and a slider 20 is fixedly connected to the output end of the electric telescopic rod 19. The electric telescopic rod 19 moves linearly in conjunction with the slider 20, achieving the effect of driving the baffles 27 to rotate. The slider 20 is slidably connected to the multiple fixed frames 17. In the middle, guide grooves 21 are provided on both sides of the inner side of slider 20. The guide grooves 21 cooperate with the connecting strips 22 to guide the movement, realizing the effect of rotating the connecting plate 23. The inner wall of one baffle 27 is fixedly connected to the second fixed cylinder 26, and the inner wall of the other baffle 27 is fixedly connected to the connecting cylinder 25.

The outer wall of the support block 28 is fixedly connected to the inner wall of the first fixed cylinder 14. The support block 28 is used to support the rotating shaft 24 and ensure the stable rotation of the baffle 27. The rotating shaft 24 and the connecting cylinder 25 are respectively fixedly connected to the connecting plate 23. Each connecting plate 23 is fixedly connected to the inner side of the guide groove 21. Each connecting strip 22 is in contact with the inner wall of the guide groove 21. The connecting strip 22 cooperates with the guide groove 21 to move in linkage, achieving the effect of synchronously controlling the opening and closing of the baffle 27.

[0037] Working principle: During the process of fixing the position of the equipment, pull the pull ring 10 to move the locking post 9 out of the slider 7. The movement of the locking post 9 will cause the connecting ring 11 to compress the spring 12. Next, the fixed suction cup 13 will be pushed downward and the slider 7 will slide inside the fixed shell 6. When the bottom of the fixed suction cup 13 is completely attached to the ground, release the pulling force on the pull ring 10. The rebound force of the spring 12 will push the locking post 9 on the inner wall of the connecting ring 11 to extend into the interior of the slider 7 again, thereby fixing the position of the fixed suction cup 13 at the bottom of the slider 7. Through the adsorption effect between the bottom of the fixed suction cup 13 and the ground, the position of the equipment is fixed. This solves the problem that the wheels at the bottom of the equipment are prone to rolling due to external accidental collisions, strong winds, or road tilts during the fixing process, which can cause the equipment position to shift and affect the feeding effect. This enhances the stability of the equipment during the feeding process.

[0038] During the precise control of the feeding amount, the spiral feeding pipe 3 transmits the pharmaceutical intermediates inside the pulverizing box 1 to the fixed cylinder 14 at the bottom of the connecting pipe 4. Multiple baffles 27 are used to block the pharmaceutical intermediates. During this process, the height of the pharmaceutical intermediates at the top of the multiple baffles 27 is detected by the height detection sensor 15. When the pharmaceutical intermediates reach a certain height, the electric telescopic rod 19 is activated. The output end of the electric telescopic rod 19 drives the slider 20 to move, and the connecting plate 23 at one end of the connecting strip 22 moves around the rotating shaft 24 through the guide grooves 21 on both sides. The rotational force of one connecting plate 23 is transmitted to the outer wall of the fixed cylinder 26 through the rotating shaft 24, and the rotational force of the other connecting plate 23 is transmitted to the surface of the connecting cylinder 25. This causes the baffles 27 on the outer walls of the connecting cylinder 25 and the fixed cylinder 26 to rotate in opposite directions, providing space for the pharmaceutical intermediate fixed cylinder 14 to flow out. This achieves the effect of controlling the amount of pharmaceutical intermediate fed, solving the problem that traditional devices are difficult to accurately control the amount of feed, especially in multi-component synthesis, where ratio errors lead to reaction failure or product quality fluctuations. This enhances the accuracy of the feeding amount on the equipment.

[0039] 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.
