[0002] Fine chemicals refer to chemical products with specific application properties and multiple synthesis steps. Examples include pharmaceuticals, pesticides, chemical reagents, surfactants, and catalysts. Fine chemicals are diverse and widely used, serving various industries. The production of fine chemicals generates a large amount of water vapor, thus requiring the use of vacuum dehumidification devices for dehumidification.

[0003] Vacuum dehumidification devices generate vibrations during operation, and prolonged vibrations can reduce the lifespan of the device. According to CN211343863 U, a vacuum dehumidification device for the preparation of fine chemical products is disclosed. This patent uses a main spring and a secondary spring for vibration damping, but relying solely on springs for vibration damping is relatively weak. In addition, the rollers in the aforementioned patent are located at the bottom of the auxiliary rod and move up and down with the vibration of the springs. This cannot ensure that the entire device will not shift or slip when vibrating. Utility Model Content

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a vacuum dehumidification and vibration damping device for fine chemical products, including a base 1. The upper surface of the base 1 is welded and fixed to the bottom surface of two symmetrical side plates 2. Symmetrical limiting grooves 3 are opened on the side of the side plates 2. The limiting grooves 3 are slidably connected to rubber wheels 4. The rubber wheels 4 are fixedly connected to the side of the mounting plate 5 through baffles. The bottom surface of the mounting plate 5 is fixedly connected to two symmetrical damping rods 6. The bottom of the damping rods 6 is fixedly connected to the upper surface of the base 1. The bottom surface of the mounting plate 5 is hinged to one end of the connecting plate 7. The other end of the connecting plate 7 is hinged to the top of the damping slider 8. The outer side of the damping rods 6 is welded and fixed to one end of two symmetrical sliding rods 9. One end of the sliding rods 9 is fixedly connected to the side of the spring 10. The bottom surface of the spring 10 is... The upper surface of the base 1 is welded and fixed. The outer side of the slide rod 9 is fitted with an ear plate 11, which is located between the damping slider 8 and the ear plate 11. The interior of the base 1 is fixedly connected to one end of the motor 12. The output end of the motor 12 is fixedly connected to one end of the worm gear 13. The interior of the base 1 is rotatably connected to the top of two symmetrical sleeves 14 through bearings. The outer side of the worm gear 13 is meshed with the worm wheel 15. The sleeves 14 are threadedly connected to the outer side of the threaded rod 16. The bottom surface of the threaded rod 16 is welded to the lifting plate 17. The bottom surface of the lifting plate 17 is fixedly connected to two symmetrical casters 18. The interior of the base 1 is welded to both ends of the guide rod 19. The guide rod 19 is slidably connected to the lifting plate 17. The upper surface of the mounting plate 5 is fixedly connected to the vacuum dehumidifier body 20.

[0022] The base 1 has four symmetrical rectangular through holes at its bottom. The positions of the casters 18 correspond to the rectangular through holes. The outer diameter of the casters 18 is smaller than the inner diameter of the rectangular through holes. The rectangular through holes facilitate the storage and removal of the casters 18 for movement, effectively improving the actual usability of the vacuum dehumidifier body 20 and reducing the difficulty of moving the vacuum dehumidifier body 20.

[0023] The inner diameter of the limiting groove 3 is matched with the outer diameter of the rubber wheel 4. The rubber wheel 4 is slidably connected to the limiting groove 3 and is fixedly connected to the side of the mounting plate 5 via a baffle. When the mounting plate 5 moves downward due to vibration, the rubber wheel 4 will slide within the limiting groove 3, thereby ensuring that the movement of the mounting plate 5 is limited and preventing the mounting plate 5 from tilting. At the same time, it makes the mounting plate 5 more stable and prevents lateral vibration of the mounting plate 5.

[0024] A circular through hole is provided inside the damping slider 8, and the damping slider 8 is slidably connected to the slide rod 9 through the circular through hole. The two ends of the ear plate 11 are fixedly connected to the sides of the damping slider 8 and the spring 10, respectively.

[0025] The outer diameter of the worm gear 13 is matched with the outer diameter of the sleeve 14. The worm gear 13 is simultaneously engaged with two symmetrical worm wheels 15, which are located on both sides of the base 1. Two symmetrical circular through holes are provided on the threaded rod 16. The guide rod 19 is slidably connected to the threaded rod 16 through the circular through holes. The drive motor 12 causes the worm gear 13 to rotate, which in turn causes the sleeve 14 and the worm wheels 15 to rotate. This causes the threaded rod 16 and the lifting plate 17 to move downwards, and the casters 18 to move out of the base 1. This allows for convenient transport and movement of the entire vacuum dehumidification device.

[0026] Working principle: During use, the vacuum dehumidifier body 20 vibrates. At this time, the mounting plate 5 moves and compresses the damping rod 6 downwards. Through the connecting plate 7, the damping slider 8 moves outwards while simultaneously pressing the ear plate 11. The contraction of the damping rod 6 and ear plate 11 absorbs the impact of the vibration, achieving a shock absorption effect. As the mounting plate 5 moves, it slides within the limiting groove 3, improving its stability and guiding its downward movement. If it is necessary to move or transport the vacuum dehumidifier body 20, the drive motor... Motor 12 causes the worm gear 13 to rotate, which in turn drives the sleeve 14 and worm wheel 15 to rotate. This further causes the threaded rod 16 and the lifting plate 17 to move downwards. The guide rod 19 limits the lifting of the lifting plate 17 until the caster wheel 18 is moved out of the base 1 and the base 1 is supported. This effectively reduces the difficulty of moving and transporting the vacuum dehumidifier body 20. After moving to the target position, motor 12 is driven again to retract the caster wheel 18 into the base 1. The bottom surface of the base 1 is used to make the vacuum dehumidifier body 20 operate stably.
