Description

Technical Field

[0001] This utility model relates to the field of metal-organic framework production technology, and in particular to a reaction vessel for metal-organic framework production. Background Technology

[0002] Metal-organic frameworks (MOFs) have demonstrated enormous application potential in numerous cutting-edge fields such as gas storage and separation, catalysis, and sensing, thanks to their high specific surface area, tunable pore structure, and unique chemical properties. In recent years, with the rapid development of industries such as new energy, environmental protection, and biomedicine, the demand for high-performance MOFs has exploded. This has prompted researchers and manufacturers to continuously explore more efficient and higher-quality production processes. As the core equipment for MOF synthesis, the performance of the reactor directly determines the quality of the product and the production efficiency, playing a key supporting role in the development of the entire industry.

[0003] When existing reactors are used for the production of metal-organic frameworks, the raw materials of metal-organic frameworks tend to adhere to the inner wall of the reactor due to their adhesive properties. Since the adhesion site is inside the device, cleaning is quite difficult. If the inner wall of the reactor is cleaned manually, it will not only be time-consuming but also lead to low work efficiency and seriously affect the production schedule. Therefore, a new reactor for the production of metal-organic frameworks is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a reaction vessel for the production of metal-organic frameworks, thereby solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reactor for the production of metal-organic frameworks includes a tank body. A threaded rod is disposed inside the tank body, with its two ends rotatably connected to the top and bottom inner walls of the tank body, respectively. A guide rod is fixedly installed inside the tank body. A first slider and a second slider are threadedly and slidably sleeved on the outer sides of the threaded rod and the guide rod, respectively. The same scraper is fixedly connected to the outer sides of the first slider and the second slider. The scraper is in contact with the inner wall of the tank body. A linkage assembly and a tilting assembly are disposed inside the tank body.

[0007] Preferably, the linkage assembly includes a motor fixedly installed on the top side of the tank body, the output end of the motor rotating through the tank body and fixedly installed with a rotating rod, and multiple stirring rods fixedly installed on the outer side of the rotating rod.

[0008] Preferably, a first pulley and a second pulley are fixedly sleeved on the outer side of the rotating rod and the outer side of the threaded rod, respectively, and the second pulley and the first pulley share the same belt.

[0009] Preferably, the flipping assembly includes a fixed block fixedly sleeved on the outer side of the rotating rod, and a first lifting plate and a second lifting plate fixedly installed on both sides of the fixed block, with both the first lifting plate and the second lifting plate being inclined.

[0010] Preferably, the top and bottom sides of the tank body are respectively provided with a feed inlet and a discharge outlet, a sealing plug is inserted into the feed inlet, and a solenoid valve is provided on the outside of the discharge outlet.

[0011] Preferably, a side plate is fixedly installed on one side of the tank body, and a controller is fixedly installed on the top side of the side plate. The controller, solenoid valve, and motor are electrically connected.

[0012] Preferably, four support legs are fixedly installed on the outer side of the tank body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A cleaning structure consisting of a threaded rod, a first slider, a scraper, and a linkage assembly is used. The two ends of the threaded rod are rotatably connected to the tank body, and the first slider is threaded on the outside. The scraper is fixed below the first slider and fits against the inner wall of the tank. The motor drives the rotating rod, which rotates the threaded rod through the first pulley, belt, and second pulley. This drives the first slider to move the scraper up and down. This solves the problem of difficult cleaning of the inner wall of existing reactors. It requires no manual labor, can efficiently scrape off the adhering metal-organic skeleton, prevent material deterioration, maintain a clean reaction environment, improve production efficiency, and ensure production progress.

[0015] 2. A fixed block is fixed to the outside of the rotating rod, and the first and second lifting plates are connected to the two sides of the rod at an incline. When the motor drives the rotating rod to rotate, the first lifting plate is rotated in the forward direction and the second lifting plate is rotated in the reverse direction to lift the metal-organic skeleton accumulated at the bottom of the tank body. In conjunction with the stirring rod, the materials are fully contacted and mixed. Compared with traditional reactors, this solves the problem of uneven material mixing, greatly improves the uniformity of metal-organic skeleton mixing, provides good conditions for the reaction, and is conducive to improving product quality and promoting efficient reaction.

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 Figure 1-4A reactor for the production of metal-organic frameworks includes a tank body 1. A threaded rod 11 is disposed inside the tank body 1, with its two ends rotatably connected to the top and bottom inner walls of the tank body 1, respectively. A guide rod 14 is fixedly installed inside the tank body 1. A first slider 15 and a second slider 16 are threadedly and slidably sleeved on the outer sides of the threaded rod 11 and the guide rod 14, respectively. A common scraper 17 is fixedly connected to the outer sides of the first slider 15 and the second slider 16, and the scraper 17 fits against the inner wall of the tank body 1. A linkage assembly and a tilting assembly are respectively disposed inside the tank body 1. The first slider 15 is threadedly sleeved on the outer side of the threaded rod 11. When the threaded rod 11 rotates, according to the threaded transmission principle, the first slider 15 moves smoothly along the axial direction of the threaded rod 11. The outer side of the first slider 15 is fixedly connected to the scraper 17, and the outer contour of the scraper 17 fits tightly against the inner wall of the tank body 1, with minimal gap between them, effectively ensuring cleaning efficiency. When the motor 7 rotates forward under the control of the controller 22, the rotating rod 8 drives the first pulley 10 to rotate. Through the belt 13, the second pulley 12 drives the threaded rod 11 to rotate, causing the first slider 15 to move downward along the threaded rod 11. The scraper 17 then scrapes down the metal-organic skeleton attached to the inner wall of the tank body 1. Conversely, when the controller 22 controls the motor 7 to rotate in reverse, the rotating rod 8 rotates in the opposite direction. Similarly, through the transmission of the pulley and belt 13, the threaded rod 11 also rotates in the opposite direction. The first slider 15 then moves upward along the threaded rod 11, and the scraper 17 also scrapes upward. In this way, under the precise control of the controller 22, the scraper 17 can continuously move up and down on the inner wall of the tank body 1, efficiently scraping off the metal-organic skeleton attached to the inner wall of the tank body 1. This keeps the inner wall of the tank relatively clean, creating an excellent environment for the mixing reaction of the metal-organic skeleton and ensuring that the reaction is not disturbed by the deposits on the inner wall, and proceeds stably and efficiently.

[0023] Specifically, the linkage component includes a motor 7 fixedly installed on the top side of the tank body 1. The output end of the motor 7 rotates through the tank body 1 and is fixedly installed with a rotating rod 8. Multiple stirring rods 9 are fixedly installed on the outer side of the rotating rod 8. A first pulley 10 and a second pulley 12 are respectively fixedly sleeved on the outer side of the rotating rod 8 and the outer side of the threaded rod 11. The second pulley 12 and the first pulley 10 share the same belt 13. By setting the first pulley 10 and the second pulley 12, and because the first pulley 10 and the second pulley 12 are driven by a belt 13, when the first pulley 10 rotates counterclockwise or clockwise, under the transmission of the belt 13, the second pulley 12 will synchronously drive the threaded rod 11 to rotate forward or reverse, so that the scraper 17 can move up and down to clean the metal organic skeleton attached to the inner wall.

[0024] Specifically, the agitation assembly includes a fixed block 18 fixedly sleeved on the outside of the rotating rod 8. A first lifting plate 19 and a second lifting plate 20 are fixedly installed on both sides of the fixed block 18, respectively. Both the first lifting plate 19 and the second lifting plate 20 are inclined. With the first lifting plate 19 and the second lifting plate 20, when the motor 7 drives the rotating rod 8 to rotate forward, the fixed block 18 will drive the first lifting plate 19 to rotate synchronously. During the forward rotation, the first lifting plate 19 can lift the metal organic skeleton accumulated at the bottom of the tank body 1, so that the lifted organic skeleton can be better contacted by the stirring rod 9. When the motor 7 drives the rotating rod 8 to rotate in reverse, the second lifting plate 20 can also lift the metal organic skeleton at the bottom, thereby greatly improving the uniform mixing of the metal organic skeleton.

[0025] Specifically, the top and bottom sides of the tank body 1 are respectively provided with an inlet 3 and an outlet 5. A sealing plug 4 is inserted into the inlet 3, and a solenoid valve 6 is provided on the outside of the outlet 5. A side plate 21 is fixedly installed on one side of the tank body 1, and a controller 22 is fixedly installed on the top side of the side plate 21. The controller 22, the solenoid valve 6, and the motor 7 are electrically connected. Four support legs 2 are fixedly installed on the outside of the tank body 1. The inlet 3 and outlet 5 are used for feeding and discharging the metal-organic skeleton. The sealing plug 4 and the solenoid valve 6 are used for sealing the tank body 1 and controlling the discharge, ensuring that the reaction takes place in a relatively closed environment and avoiding interference from external impurities. The controller 22 can control the forward and reverse rotation of the motor 7, so that the scraper 17 can move up and down on the inner wall of the tank body 1, continuously and efficiently scraping off the metal-organic skeleton attached to the inner wall of the tank body 1, ensuring that the inner wall of the tank is always kept relatively clean.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: When carrying out the mixing reaction of metal-organic frameworks, firstly, the required metal-organic framework raw materials are poured into the tank body 1 through the feed port 3. Then, the sealing plug 4 is tightly inserted into the feed port 3 to complete the sealing of the tank body 1, ensuring that the reaction takes place in a relatively closed environment and avoiding interference from external impurities. When it is necessary to start the stirring operation, the motor 7 is turned on to drive the rotating rod 8 to rotate. Multiple stirring rods 9 are fixedly installed on the outside of the rotating rod 8, which can fully stir the metal-organic framework raw materials in the tank body 1, promote uniform mixing between the raw materials, and accelerate the reaction process. Because the first pulley 10 is fixedly sleeved on the outside of the rotating rod 8, and the first pulley 10 and the second pulley 12 are connected by the same belt 13, under the transmission action of the belt 13, when the rotating rod 8 drives the first pulley 10 to rotate, the second pulley 12 will also rotate synchronously. Since the second pulley 12 is fixedly connected to the threaded rod 11, the rotation of the second pulley 12 can drive the threaded rod 11 to rotate together. The threaded rod 11 is threadedly sleeved on the outside of the first slider 15. When the screw rod 11 rotates, according to the principle of screw drive, the first slider 15 will move along the axial direction of the screw rod 11. A scraper 17 is fixedly connected below the first slider 15, and the outer side of the scraper 17 is in close contact with the inner wall of the tank body 1. Therefore, when the first slider 15 moves downward under the drive of the screw rod 11, the scraper 17 can scrape off the metal-organic framework attached to the inner wall of the tank body 1. Because the metal-organic framework raw material has a certain degree of adhesion, if it is attached to the inner wall of the tank for a long time, it may deteriorate and affect the subsequent reaction. And product quality, by setting up a controller 22, which has the function of controlling the forward and reverse rotation of the motor 7, through the regulation of the controller 22, when the motor 7 rotates forward, the scraper 17 moves downward to scrape off the attached material, and when the motor 7 rotates in reverse, the scraper 17 moves upward. In this way, the scraper 17 can move up and down back and forth on the inner wall of the tank body 1, continuously and efficiently scraping off the metal-organic skeleton attached to the inner wall of the tank body 1, ensuring that the inner wall of the tank is always kept in a relatively clean state, providing a good environment for the mixing reaction of the metal-organic skeleton.
