Description

Technical Field

[0001] This utility model relates to the field of metal-organic framework material preparation technology, and in particular to a doping device for metal-organic framework materials. Background Technology

[0002] Metal-organic framework materials typically refer to crystalline materials that form a periodic, infinite network structure by self-assembly of metal ions or metal clusters with organic ligands. As they are inorganic-organic hybrid systems, they combine the characteristics of both organic polymers and inorganic compounds, exhibiting many unique properties and being widely used in energy production, green catalysis, and other fields.

[0003] In the production of metal-organic framework materials, ligands, metal sources, and reaction solvents from corresponding storage tanks need to be added to a pressure-controlled reactor in the appropriate proportions for stirring to allow them to mix and react. Then, azeotropic washing and drying are performed. During the doping process, raw materials are added directly from top to bottom, and all raw materials are added at once. After addition, raw materials of the same component accumulate together, making it difficult to quickly and thoroughly mix them, which increases the doping and mixing time. Therefore, a doping device for metal-organic framework materials is proposed. Utility Model Content

[0014] The liquid addition component is designed so that when liquid raw materials need to be added for doping, the liquid raw materials in the injection tank are transported to the vertical pipe after the push rod moves, and finally flow out from multiple liquid outlet pipes.

[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] Example: Refer to Figure 1-4 A doping device for a metal-organic framework material includes a doping stirring tank 1, a side extension 2 on the side of the doping stirring tank 1, and a stirring drive assembly inside the doping stirring tank 1. The stirring drive assembly includes a drive motor 3 fixedly installed at the bottom of the doping stirring tank 1, and a rotating shaft 4 connected to the output end of the drive motor 3. The rotating shaft 4 extends into the doping stirring tank 1, and multiple stirring rods 5 are provided on the rotating shaft 4. When the main ligand support is placed inside the doping stirring tank 1, the drive motor 3 on the stirring drive assembly is started to run, driving the rotating shaft 4 to rotate, thereby driving the multiple stirring rods 5 to rotate. Through rotational stirring, the raw materials in the doping stirring tank 1 can be stirred.

[0022] Specifically, the top of the doping mixing tank 1 is provided with a top circular box 6, the interior of which is hollow. A solid addition tank 8 is connected to the top of the top circular box 6. A metering addition component is connected to the stirring drive assembly and is located inside the top circular box 6. The metering addition component includes a rotating disk 9 fixedly mounted on the top of the stirring rod 5. A placement notch 10 is provided on one side of the rotating disk 9. The rotating disk 9 has a fan-shaped structure and is located inside the top circular box 6. A rotating drop hole 11 is provided at the bottom of the top circular box 6, and the rotating drop hole 11 is connected to the doping mixing tank 1. The rotating drop hole 11 is adapted to the placement notch 10. During the stirring process, the rotating shaft 4 rotates, driving the rotating disk 9 on the metering addition component to rotate. The rotating disk 9 has a placement notch 10. When the placement notch 10 rotates to below the solid addition tank 8, the solid addition tank 8... The raw material falls from the connected pipe 7 and into the placement notch 10. The rotation speed remains constant, and the amount falling each time is kept quantitative. The falling raw material moves as the placement notch 10 rotates. When the placement notch 10 rotates above the rotating drop hole 11, the quantitative raw material will fall from the rotating drop hole 11, realizing quantitative falling doping and avoiding the problem of adding too much at once and poor mixing effect. The top of the top round box 6 is provided with multiple connected pipes 7, and the diameter of the multiple connected pipes 7 gradually increases. The solid addition bucket 8 is installed on the connected pipes 7. The top round box 6 has multiple connected pipes 7, each with a different diameter. The operator can select the appropriate connected pipe 7 as needed, so as to achieve different quantitative falling amounts each time. The diameter of the opening of the solid addition bucket 8 is large, and the feeding speed is only related to the diameter of the connected pipe 7.

[0023] Specifically, a liquid addition assembly is provided on the side extension 2. The liquid addition assembly includes a vertical tube 12 on the side extension 2, and multiple liquid outlet pipes 13 on one side of the vertical tube 12. An injection tank 14 is threadedly connected to the top of the vertical tube 12. A push rod 15 is connected to the injection tank 14, and a push piston 16 is connected to one end of the push rod 15. The push piston 16 is located inside the injection tank 14. When liquid raw materials need to be added for mixing, the operator presses the push rod 15. The push rod 15 moves, driving the push piston 16 to move. After the push piston 16 moves, the liquid raw materials in the injection tank 14 are transported to the vertical tube 12 and finally flow out from the multiple liquid outlet pipes 13. The liquid outlet pipes 13 are vertically equidistant. With the rotation of the stirring rod 5, liquid raw materials are evenly added to each layer of raw materials, thereby quickly and fully achieving the mixing of raw materials and achieving a better mixing effect.

[0024] In use: During the preparation of metal-organic framework materials, ligands, metal sources, and reaction solvents are added and mixed in appropriate proportions. During the doping and mixing process, the main ligand support is placed in the doping stirring tank 1, and then other solid raw materials are placed in the solid addition tank 8. The liquid is placed in the injection tank 14. The drive motor 3 on the stirring drive assembly is started, driving multiple stirring rods 5 to rotate. Through rotation and stirring, the raw materials in the doping stirring tank 1 can be stirred. During the stirring process, the rotating shaft 4 rotates, driving the rotating disk 9 on the metering addition assembly to rotate. The raw materials in the solid addition tank 8 are released from the connected connecting pipe. The material falls in 7, and the amount falling each time is kept constant. The falling material moves with the rotation of the placement notch 10 and falls from the rotating drop hole 11, realizing quantitative falling doping and avoiding the problem of adding too much at once and poor mixing effect. When liquid material needs to be added for doping, the operator presses the push rod 15 to deliver the liquid material in the injection tank 14 to the vertical pipe 12, and finally flows out from multiple liquid outlet pipes 13. The liquid outlet pipes 13 are vertically equidistant. With the rotation of the stirring rod 5, liquid material is evenly added to each layer of material, so as to quickly and fully realize the doping of the material, with better doping and mixing effect and convenient use.
