Description

Technical Field

[0001] The present application relates to the technical field of chemical preparation, in particular to a chemical reagent preparation machine. Background Art

[0002] Chemical reagent preparation machine is a device used to automatically prepare various chemical reagents. It integrates multiple functions and units, and can automatically complete the entire preparation process from raw material preparation, weighing, mixing, reaction to purification, separation, collection, etc. The use of chemical reagent preparation machine greatly improves the preparation efficiency, reduces human operation errors, and ensures the quality and stability of the reagents.

[0003] In the process of preparing chemical reagents, mixing and stirring are very important. In the prior art, stirring is often performed in the wall shell of the mixer. During the stirring or mixing process, the central part and the part close to the container wall may not be mixed evenly. When the fluid flows in the container, the shear force (that is, the internal friction generated by the fluid flow) at different positions may be different, which ultimately leads to uneven reaction of the reactants. Therefore, the present application provides a chemical reagent preparation machine. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a chemical reagent preparation machine to solve the technical problem of low reaction rate when the reagent is stirred.

[0005] The above-mentioned purpose of the present application is achieved through the following technical scheme: a chemical reagent preparation machine, including a working platform, a fixed shell and a rotating shell, the bottom of the fixed shell is fixedly provided with a placement magnet, the outer side of the bottom of the rotating shell is fixedly provided with and installed with repulsive magnets that repel each other, the rotating shell is rotatably connected in the fixed shell, the bottom of the fixed shell is installed on the working platform, a pair of storage rods are installed on the working platform, a docking rod is arranged between the pair of storage rods, a stirring rod is rotatably arranged on the docking rod, a stirring plate is fixedly arranged on the rod body of the stirring rod, a motor is fixedly arranged on the docking rod, and the output end of the motor is fixedly connected to the stirring rod.

[0006] By adopting the above technical solution, when stirring is required, different reagents are put into the rotating shell, and the motor is started to drive the stirring rod to rotate. The stirring blades fixed on the stirring rod will stir the reagents, thereby forming a vortex. At this time, since the fixed shell is fixed, and the rotating shell is equivalent to being connected to the fixed shell by rotation, the rotating shell will be driven by the vortex to rotate together. Since two magnets for repulsion are installed between the rotating shell and the fixed shell, the resistance will be very small, so it is easy to form a high-speed vortex, change the uneven distribution of flow field velocity caused by the high viscosity of the polymer reagent, make fewer collisions between the monomers contained in the reagent, inhibit the formation of a short-chain cross-linked network structure, promote the embedding of groups to form long-chain compounds, and make the reagents fully stirred and react in the rotating shell.

[0007] Furthermore, a threaded groove is provided inside the rotating shell.

[0008] By adopting the above technical solution, the spiral groove is opened to create a vortex when the stirring blade on the stirring rod stirs the reagent, and then the spiral groove is used to increase the rotation speed of the rotating shell, thereby further allowing the reagents to be fully mixed and reacted.

[0009] Furthermore, an outer shell ring is fixedly provided on the upper edge of the fixed shell, and an inner shell ring is fixedly provided on the upper edge of the rotating shell. Buckles are provided on the outer shell ring and the inner shell ring, and the buckles are inserted outside the outer shell ring and the inner shell ring. The buckles are evenly distributed on the outer shell ring and the inner shell ring.

[0010] By adopting the above technical solution, considering that the rotating shell rotating at high speed may be slowly lifted from the fixed shell due to centrifugation, the reagent may be separated, so the outer shell ring on the fixed shell and the outer buckle on the inner shell ring on the rotating shell are used to prevent them from being separated. Thus, the problem that the rotating shell is lifted from the outer shell ring when rotating at high speed is solved.

[0011] Furthermore, a sliding circular groove is provided on the outer shell ring, and the buckle is connected by sliding in a circular and smooth manner.

[0012] By adopting the above technical solution, considering that the buckle will affect the rotation of the rotating shell with the vortex, the sliding circular groove on the outer shell ring can not only fix the outer shell ring and the inner shell ring, but also allow the buckle to slide in the sliding circular groove.

[0013] Furthermore, the docking rod is slidably connected to a stack of storage rods.

[0014] By adopting the above technical solution, the purpose of slidingly connecting the docking rod to the storage rod is to allow the stirring rod to move up and down, thereby facilitating the cleaning of the stirring rod.

[0015] Furthermore, a reagent discharge rack is provided on the platform, a placement container is fixedly provided on the reagent discharge rack, a plurality of inlet pipes are connected to the upper end of the placement container, an outlet pipe is connected to the lower end of the placement container, and the other end of the outlet pipe is connected to the rotating shell.

[0016] By adopting the above technical solution, considering that a variety of reagents need to be placed and then mixed, different reagents are first added through the inlet pipe and then discharged into the rotating shell in a centralized manner.

[0017] Furthermore, the plurality of inlet pipes are all spiral-shaped.

[0018] By adopting the above technical solution, different medicines can be preliminarily mixed before being placed in the placement container.

[0019] Furthermore, a stop valve is installed at one end of the outlet pipe close to the container.

[0020] By adopting the above technical solution, considering that different medicines need to be placed for different times, the stop valve can allow them to be placed in the placement container.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. The stirring rod and stirring blade are driven by a motor to generate eddy currents in the rotating shell, and the rotating shell rotates to achieve efficient stirring and mixing of the reagents. This design ensures that the reagents can be fully mixed during the preparation process, improving the preparation efficiency. At the same time, the design of the repelling magnet makes the resistance of the rotating shell very small when it rotates in the fixed shell, thereby changing the problem of uneven distribution of flow field velocity caused by the high viscosity of the polymer reagent, making fewer collisions between the monomers contained in the reagent, inhibiting the formation of a short-chain cross-linked network structure, and promoting the formation of long-chain compounds by group embedding, thereby improving the stirring efficiency.

[0023] 2. The threaded grooves in the rotating shell can further enhance the vortex effect, allowing the reagents to mix and react more fully in the rotating shell.

[0024] 3. The design of the outer shell ring, the inner shell ring and the buckle effectively prevents the rotating shell from being lifted from the fixed shell during high-speed rotation, ensuring the safety and stability of the preparation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] Example, see Figure 1 , Figure 2 , Figure 3 The chemical reagent preparation machine includes a working platform 1, a fixed shell 11 and a rotating shell 12. A placement magnet is fixedly arranged at the bottom of the fixed shell 11. A repelling magnet 17 is fixedly arranged and installed on the outer side of the bottom of the rotating shell 12. The rotating shell 12 is rotatably connected in the fixed shell 11. The bottom of the fixed shell 11 is installed on the working platform 1. A pair of placement rods 2 are installed on the working platform 1. A docking rod 21 is arranged between the pair of placement rods 2. A stirring rod 23 is rotatably arranged on the docking rod 21. A stirring piece 24 is fixedly arranged on the rod body of the stirring rod 23. A motor 22 is fixedly arranged on the docking rod 21. The output end of the motor 22 is fixedly connected to the stirring rod 23. When stirring is required, different medicines are put into the rotating shell 12. The starting motor 22 drives the stirring rod 23 to rotate, and the stirring blade 24 fixedly arranged on the stirring rod 23 will stir the reagent to form a vortex. At this time, since the fixed shell 11 is fixed, and the rotating shell 12 is equivalent to being connected to the fixed shell 11 by rotation, the rotating shell 12 will be driven by the vortex to rotate together. Since two magnets for repulsion are installed between the rotating shell 12 and the fixed shell 11, the resistance will be very small, so that the resistance of the rotating shell 12 when rotating in the fixed shell is very small, thereby changing the problem of uneven distribution of flow field velocity caused by the high viscosity of the polymer reagent, causing fewer collisions between the monomers contained in the reagent, inhibiting the formation of a cross-linked network structure of short chains, and promoting the embedding of groups to form long-chain compounds, thereby improving the stirring efficiency.

[0031] In this embodiment, a spiral groove 18 is provided inside the rotating shell 12. The spiral groove is provided to create a vortex when the stirring blade 24 on the stirring rod 23 stirs the reagent, and the spiral groove 18 is used to increase the rotation speed of the rotating shell 12, thereby further allowing the reagents to be fully mixed and reacted.

[0032] In this embodiment, an outer shell ring 13 is fixedly provided on the upper edge of the fixed shell 11, and an inner shell ring 14 is fixedly provided on the upper edge of the rotating shell 12. Buckles 15 are provided on the outer shell ring 13 and the inner shell ring 14. The buckles 15 are inserted outside the outer shell ring 13 and the inner shell ring 14, and the buckles 15 are evenly distributed on the outer shell ring 13 and the inner shell ring 14. Considering that the rotating shell 12 rotating at a high speed may be slowly lifted from the fixed shell 11 due to centrifugation, the reagent may be separated, so the buckles 15 outside the outer shell ring 13 on the fixed shell 11 and the inner shell ring 14 on the rotating shell 12 prevent them from being separated. Thus, the problem that the rotating shell 12 is lifted from the outer shell ring 13 when rotating at a high speed is solved.

[0033] In this embodiment, a sliding circular groove 19 is opened on the outer shell ring 13, and one end of the buckle 15 is slidably connected. Considering that the buckle 15 will affect the rotation of the rotating shell 12 with the eddy current, the sliding circular groove 19 on the outer shell ring 13 can not only fix the outer shell ring 13 and the inner shell ring 14, but also allow one end of the buckle 15 to slide in the sliding circular groove 19.

[0034] In this embodiment, the docking rod 21 is slidably connected to a stack of storage rods 2. The purpose of the docking rod 21 being slidably connected to the storage rod 2 is to allow the stirring rod to move up and down, so as to facilitate cleaning of the stirring rod.

[0035] In this embodiment, a reagent discharge rack 32 is also provided on the platform 1, and a placement container 3 is fixedly provided on the reagent discharge rack 32. A plurality of inlet pipes 31 are connected to the upper end of the placement container 3, and an outlet pipe 33 is connected to the lower end of the placement container 3. The other end of the outlet pipe 33 is connected to the rotating shell 12. Considering that multiple reagents need to be placed and then mixed, different reagents are first added through the inlet pipe 31 and then discharged into the rotating shell 12 in a centralized manner. The plurality of inlet pipes 31 are all spiral-shaped, so that different reagents can be initially mixed before entering the placement container 3 and then placed. A stop valve 34 is installed at one end of the outlet pipe 33 close to the placement container 3. Considering that different reagents have different placement times, the stop valve 34 allows them to be placed in the placement container 3.

[0036] Specific implementation process: Different types of chemical reagents are added to the placement container 3 through the spiral inlet pipe 31 according to the experimental requirements. The order and amount of reagent addition can be adjusted as needed. After all reagents are added, the stop valves 34 of all inlet pipes 31 are closed to prevent reagent leakage, and the motor 22 is started. The motor 22 will drive the stirring rod 23 and the stirring blade 24 to rotate in the rotating shell 12 to form an eddy current. Due to the effect of the eddy current and the design of the repelling magnet 17, the rotating shell 12 will rotate accordingly, and work together with the stirring rod 23 to fully stir and mix the reagents in the rotating shell 12. The design of the threaded slide 18 will further improve the stirring effect and make the reagents more evenly mixed.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
