Description

Technical Field

[0001] This utility model relates to the field of accelerated dissolution instruments, specifically to an accelerated dissolution instrument for chemical analysis. Background Technology

[0002] Chemical analysis accelerated dissolution instruments are devices used to accelerate the dissolution process of chemical substances. These instruments provide heating while stirring, which can control the temperature of the solution and improve solubility. Through the dual action of heating and stirring, the dissolution of solutes is accelerated.

[0003] The existing technology has the following problems:

[0004] Existing devices cannot perform up-and-down stirring during the stirring process. When the stirring rod rotates in only one direction, local concentration and temperature gradients easily form in the solution. During stirring, the solute may only mix with the solvent in a local area and cannot effectively diffuse into the entire solution system, resulting in slow dissolution or even incomplete dissolution. In addition, existing devices cannot limit and fix the storage tank. If the storage tank is not limited and fixed during stirring, it may tip over when the instrument is subjected to external forces, such as vibration of the experimental table or collision with personnel. This could cause the solution to spill, potentially causing burns, corrosion, or other injuries to the experimental personnel. Utility Model Content

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1As shown, this utility model provides a chemical analysis instrument for accelerating dissolution, including a base 1, an annular seat 7 fixedly connected to the upper side of the base 1, a slide 2 fixedly connected to the upper side of the base 1, a lifting plate 3 slidably connected to the front side of the slide 2, a motor 4 fixedly connected to the upper side of the lifting plate 3, multiple guide posts 5 fixedly connected to the lower side of the lifting plate 3, and a cover plate 6 fixedly connected to the lower end of the guide posts 5. A liquid storage tank 8 is arranged inside the annular seat 7, and a heating plate is arranged inside the liquid storage tank 8. The heating plate can provide heating function during the stirring process of the device to accelerate the dissolution of solute. The base 1 serves as the basic support structure of the entire instrument, providing a stable placement platform. The annular seat 7 is used to place the liquid storage tank 8. The combination of the slide 2 and the lifting plate 3 allows the lifting plate 3 to slide on the slide 2, thereby realizing the function of moving up and down. The motor 4 is installed on the lifting plate 3 and can move up and down with the movement of the lifting plate 3. The cover plate 6 can contact the liquid storage tank 8 when the lifting plate 3 descends, playing a certain role in sealing or protecting it, and also providing a relatively closed space environment for subsequent stirring and other operations.

[0024] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, the output end of the motor 4 is fixedly connected to a drive shaft 9, the outer wall of the drive shaft 9 is slidably connected to a rotating shaft 11, the outer wall of the rotating shaft 11 is fixedly connected to a plurality of stirring rods 12, the lower side of the cover plate 6 is movably connected to the storage tank 8, the lower side of the cover plate 6 is fixedly connected to a fixing column 10, the outer wall of the drive shaft 9 is fixedly connected to a plurality of limiting strips 13, the outer wall of the limiting strips 13 is slidably connected to the rotating shaft 11, the outer wall of the drive shaft 9 is fixedly connected to a first connecting plate 15, the outer wall of the rotating shaft 11 is fixedly connected to a second connecting plate 17, the upper side of the second connecting plate 17 is fixedly connected to a plurality of telescopic columns 16, the outer wall of the telescopic columns 16 is sleeved with a spring 18, the outer wall of the second connecting plate 17 is fixedly connected to a limiting column 19, the inner surface of the fixing column 10 is provided with an annular inclined groove 14, the outer wall of the limiting column 19 is slidably connected to the annular inclined groove 14, one end of the spring 18 is fixedly connected to the first connecting plate 15, and the other end of the spring 18 is fixedly connected to the second connecting plate 17. Next, the upper end of the telescopic column 16 is fixedly connected to the first connecting plate 15. After the motor 4 starts, the drive shaft 9 starts to rotate. Since the outer wall of the limiting strip 13 is slidably connected to the rotating shaft 11, the rotation of the drive shaft 9 will drive the rotating shaft 11 to rotate together, thereby causing the stirring rod 12 to rotate and stir the solution in the storage tank 8. At the same time, when the drive shaft 9 rotates, the limiting column 19 slides along the annular inclined groove 14 on the inner surface of the fixed column 10. Since the annular inclined groove 14 is inclined, the limiting column 19 will drive the second connecting plate 17 and the rotating shaft 11 and stirring rod 12 connected to the second connecting plate 17 to move up and down during the sliding process. During this process, the telescopic column 16 will extend and retract with the up and down movement of the second connecting plate 17, and the spring 18 will also be compressed or stretched accordingly, playing a role in buffering and assisting in reset. In this way, the stirring rod 12 can also perform up and down reciprocating motion while rotating and stirring, so that the solute and solvent in the solution can be fully mixed in the vertical direction, improving the dissolution rate.

[0025] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a knob 20 is rotatably connected to the upper side of the annular seat 7, and a rotating rod 21 is fixedly connected to the lower side of the knob 20. A first gear 22 is fixedly connected to the lower end of the rotating rod 21. A gear ring 23 is meshed with the outer wall of the first gear 22. Two second gears 24 are meshed with the outer wall of the gear ring 23. A threaded rod 25 is fixedly connected to the upper side of the second gear 24. A lifting block 27 is threadedly connected to the outer wall of the threaded rod 25. A rotating plate 26 is rotatably connected to the side of the lifting block 27 near the liquid storage tank 8. A limit frame 28 is rotatably connected to the other end of the rotating plate 26. The outer wall of the liquid storage tank 8 is movably connected to the limit frame 28. The upper end of the threaded rod 25 is rotatably connected to the annular seat 7. A limit ring is provided on the lower side of the gear ring 23. The outer wall of the limit ring is rotatably connected to the annular seat 7. Rotating the knob 20... The rotating rod 21 rotates, and the first gear 22 at the lower end of the rotating rod 21 rotates accordingly. Since the first gear 22 meshes with the gear ring 23, the rotation of the first gear 22 will drive the gear ring 23 to rotate. The gear ring 23 meshes with two second gears 24, so the rotation of the gear ring 23 will drive the second gear 24 to rotate. The rotation of the second gear 24 will cause the threaded rod 25, which is fixedly connected to it, to rotate. Since the lifting block 27 is threadedly connected to the threaded rod 25, the rotation of the threaded rod 25 will cause the lifting block 27 to move up and down along the threaded rod 25. When the lifting block 27 moves, it will drive the limiting frame 28 to move through the rotating plate 26. Finally, the limiting frame 28 can limit and fix the liquid storage tank 8, thereby effectively preventing the liquid storage tank 8 from tipping over, avoiding the solution from spilling and causing injury to the experimental personnel, reducing equipment damage caused by collisions, and extending the service life of the instrument.

[0026] The working principle of this chemical analysis accelerated dissolution instrument will be explained in detail below.

[0027] like Figure 1-5As shown, after the motor 4 starts, the drive shaft 9 begins to rotate. Since the outer wall of the limiting strip 13 is slidably connected to the rotating shaft 11, the rotation of the drive shaft 9 will drive the rotating shaft 11 to rotate as well, thereby causing the stirring rod 12 to rotate and stir the solution in the storage tank 8. At the same time, when the drive shaft 9 rotates, the limiting post 19 slides along the annular inclined groove 14 on the inner surface of the fixed post 10. Since the annular inclined groove 14 is inclined, the limiting post 19 will drive the second connecting plate 17 and the rotating shaft 11 and stirring rod 12 connected to the second connecting plate 17 to move up and down during the sliding process. During this process, the telescopic post 16 will extend and retract with the up and down movement of the second connecting plate 17, and the spring 18 will also be compressed or stretched accordingly, playing a role in buffering and assisting in reset. In this way, the stirring rod 12 can rotate and stir while also performing up and down reciprocating motion, so that the solute and solvent in the solution can be fully mixed in the vertical direction. The combination of the two gears increases the dissolution speed. Turning knob 20 causes the rotating rod 21 to rotate, and the first gear 22 at the lower end of the rotating rod 21 rotates accordingly. Since the first gear 22 meshes with the gear ring 23, the rotation of the first gear 22 will drive the gear ring 23 to rotate. The gear ring 23 meshes with two second gears 24, so the rotation of the gear ring 23 will drive the second gears 24 to rotate. The rotation of the second gears 24 will cause the threaded rod 25, which is fixedly connected to it, to rotate. Since the lifting block 27 is threadedly connected to the threaded rod 25, the rotation of the threaded rod 25 will cause the lifting block 27 to move up and down along the threaded rod 25. When the lifting block 27 moves, it drives the limiting frame 28 to move through the rotating plate 26. Finally, the limiting frame 28 can limit and fix the liquid storage tank 8, thereby effectively preventing the liquid storage tank 8 from tipping over, avoiding the solution from spilling and causing injury to the experimental personnel, reducing equipment damage caused by collisions, and extending the service life of the instrument.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
