Description

TECHNICAL FIELD

[0001] The utility model relates to the field of metal organic framework synthesis technology, especially to a metal organic framework electrochemical synthesis device. BACKGROUND

[0002] Metal organic framework has regular and highly ordered pore and cavity structure, and the pore size can be accurately controlled in the range of angstrom to nanometer scale. This structural feature makes metal organic framework have potential application value in the fields of gas storage, separation and catalysis. By selecting different metal ions and organic ligands, metal organic framework materials with different structures and properties can be synthesized.

[0003] In the process of electrochemical synthesis of metal organic framework, electrolysis is usually used. Oxidation reaction occurs at the anode, and metal ions dissolve from the anode into the solution. Reduction reaction occurs at the cathode, and metal ions in the solution get electrons on the cathode surface to form metal organic framework by coordination reaction with organic ligands.

[0004] Therefore, in the process of electrochemical synthesis, the anode, cathode and electrolyte are particularly important. However, during the synthesis process, impurities, reaction intermediates or products in the electrolyte may be adsorbed on the surface of the electrode, causing the electrode surface to be wrapped by impurities, reaction intermediates or products, so that the active sites on the surface of the electrode are occupied, thereby affecting the efficiency and selectivity of the electrode reaction. Based on the above problems, the present application provides a metal organic framework electrochemical synthesis device. UTILITY MODEL CONTENT

Detailed Implementation

[0021] 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.

[0022] Reference Figures 1-5An electrochemical synthesis device for a metal-organic framework includes an electrochemical synthesis chamber 1. A first conductive plate 2 and a second conductive plate 3 are mounted on the top of the chamber 1. A cathode rod 5 is installed inside the first conductive plate 2, and an anode rod 4 is installed inside the second conductive plate 3. A drain pipe 6 is fixedly installed on the right side of the chamber 1, and a control valve is fixedly installed on the drain pipe 6. A support plate 7 is fixedly installed on the left side of the chamber 1. A filter box 8 is fixedly installed on the top of the support plate 7. An outlet pipe 26 and a drain pipe 27 are fixedly installed at the bottom of the filter box 8. The filter box 8 contains... The switchable filter assembly includes a flip-up component on the surface of the filter box 8. A number of nozzles 21 are symmetrically distributed on the top of the filter box 8 via the flip-up component. The nozzles 21 are fan-shaped, ensuring that there are areas on the filter screen 13 that the nozzles cannot reach, thus achieving a cleaner filter screen 13. A conveying component is located on the left side of the support plate 7. The switchable filter assembly includes a servo motor 9 fixedly installed at the rear of the filter box 8. A rotating shaft 10 is fixedly installed at the output end of the servo motor 9. A mounting sleeve 11 is fixedly mounted on the surface of the moving shaft 10. Partition plates 12 are fixedly mounted on both the upper and lower sides of the mounting sleeve 11, and filter screens 13 are fixedly mounted on both the left and right sides of the mounting sleeve 11. The sides of the partition plates 12 and the filter screens 13 away from the mounting sleeve 11 are both arc-shaped surfaces. The arc-shaped surfaces of both the partition plates 12 and the filter screens 13 are in contact with the inner wall of the filter box 8, ensuring that the partition plates 12 and the filter screens 13 are not obstructed by the filter box 8 when moving, thus preventing the partition plates 12 and the filter screens 13 from being unable to rotate. The servo motor 9 drives the rotating shaft 10 to rotate, causing the mounting sleeve 11 to move the partition plate 12 and the filter screen 13 simultaneously. This allows the positions of the left and right filter screens 13 and the upper and lower mounting sleeves 11 to be interchanged. The electrolyte is filtered through the unused filter screen 13, and the filter screen 13 with excessive impurities can be cleaned. This allows for continuous filtration of the electrolyte, avoiding the time wasted in cleaning the filter screen 13, which would reduce the speed of electrolyte filtration and thus ensure the speed of the metal-organic framework electrochemical synthesis device.

[0023] Specifically, the tilting assembly includes a fixed plate 14 fixedly installed on the left side of the filter box 8. A drive motor 15 is fixedly installed on the front side of the fixed plate 14. A drive wheel 16 is fixedly installed at the output end of the drive motor 15. A transmission belt 17 is meshed inside the drive wheel 16. A driven wheel 18 is meshed inside the transmission belt 17. A rotating shaft 19 is fixedly installed inside the driven wheel 18. The rotating shaft 19 has a circular structure and is made of metal. A support seat is rotatably installed on the surface of the rotating shaft 19. The support seat is fixedly installed on the top of the filter box 8. A tilting plate 20 is fixedly installed on the surface of the rotating shaft 19. A nozzle 21 is fixedly installed inside the tilting plate 20. The conveying assembly includes a connecting plate 22 fixedly installed on the left side of the support plate 7. A conveying pump 23 is fixedly installed on the top of the connecting plate 22. A connecting hose 24 is fixedly installed at the outlet end of the conveying pump 23. A diverter pipe 25 is fixedly installed at the outlet end of the connecting hose 24. The bottom of the diverter pipe 25 is connected to the inlet end of the nozzle 21. When the positions of the two filter screens 13 are interchanged, the drive motor 15 drives the output end to rotate the drive wheel 16. The drive wheel 16 drives the driven wheel 18 to rotate through the transmission belt 17, and the driven wheel 18 drives the rotating shaft 19 to rotate inside the support base. This causes the rotating shaft 19 to rotate the flip plate 20 to the right, and the flip plate 20 drives the nozzle 21 to move. This causes the nozzle 21 to move the diversion pipe 25, and the diversion pipe 25 to move the water outlet end of the connecting hose 24. This causes the nozzle 21 to move to the top of the filter screen 13 that needs to be cleaned. The delivery pump 23 draws in external water flow and delivers the water flow to the diversion pipe 25 through the connecting hose 24 for diversion. The diverted water flow is sprayed onto the filter screen 13 through the nozzle 21. The water flow washes off the impurities attached to the filter screen 13, and the impurities are discharged through the drain pipe 27 with the water flow. This can automatically clean the filter screen 13, making it easier to clean.

[0024] The metal-organic framework electrochemical synthesis device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0025] In use: The prepared electrolyte is delivered into the filter box 8. The electrolyte is blocked by the partition plate 12, allowing it to pass through the filter screen 13 on the right side for filtration. After filtration, the electrolyte enters the electrochemical synthesis box 1 through the outlet pipe 26. When the anode rod 4 and cathode rod 5 are energized, metal ions dissolve from the anode into the solution and undergo a reduction reaction at the cathode. The metal ions in the solution gain electrons on the cathode surface and undergo coordination reactions with organic ligands to form a metal-organic framework. When too many impurities accumulate on the filter screen 13 on the right side, the output end of the servo motor 9 drives the rotating shaft 10 to rotate, which in turn drives the mounting sleeve 11 to rotate. This causes the mounting sleeve 11 to move the partition plate 12 and the filter screen 13, resulting in the left and right filter screens 13 being interchanged. At the same time, the upper and lower mounting sleeves 11 are also interchanged. The electrolyte is then filtered by moving to the filter screen 13 on the right side, and the filter screen 13 with excessive impurities is cleaned.
