Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically to a soft-drive magnetically coupled high-temperature and high-pressure reaction vessel. Background Technology
[0002] The soft-drive magnetically coupled high-temperature and high-pressure reactor adopts advanced magnetic coupling technology to achieve contactless transmission, which improves the durability and safety of the equipment. This reactor can carry out stable stirring reactions under high temperature and high pressure environments, and is suitable for various chemical reaction needs. At the same time, it can efficiently mix reactants, advance the reaction process, and ensure the purity and precision of the reaction.
[0003] Chinese patent CN206587715U discloses a soft-drive magnetically coupled high-temperature and high-pressure reactor, including a reactor body. A stirring shaft is installed inside the reactor body. A connecting seat is installed on one side of the stirring shaft extending beyond the reactor body. The connecting seat has a through hole, and a heat insulation block is fitted inside the through hole. The end of the heat insulation block near the stirring shaft has a first mating groove that matches the stirring shaft. The end of the heat insulation block away from the stirring shaft has a second mating groove. A rotating shaft is installed on the second mating groove, and an electromagnetic coupler is installed on the rotating shaft. A drive motor is installed on the electromagnetic coupler. This invention effectively prevents heat from evaporating from the reactor interior with the stirring shaft, ensuring the internal temperature of the reactor, reducing energy loss, saving energy, improving efficiency, increasing the reaction efficiency of the reactor, preventing the electromagnetic coupler from overheating, ensuring the safety of the electromagnetic coupler, and extending the service life of the electromagnetic coupler.
[0004] The aforementioned patent still has the following shortcomings: it has the defect that reactants are prone to overflow from the injection port. During the use of the device, some raw materials need to be injected into the device during the reaction process. However, under high temperature and high pressure, it is easy for reactants or products to flow back from the reactor into the feed pipe, causing the relevant pipes to bear additional pressure and impact due to the backflow, thus reducing the service life of the equipment. Utility Model Content
[0005] This invention provides a soft-drive magnetically coupled high-temperature and high-pressure reactor that solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] An embodiment of this utility model provides a soft-drive magnetically coupled high-temperature and high-pressure reactor, including an insulation shell, and further comprising:
[0008] A liquid guide port is installed on one side of the bottom end of the insulation shell, and a support frame is fixed to the bottom end of the insulation shell;
[0009] The inner shell is fixed inside the insulation shell, and a discharge port is fixed at the bottom of the inner shell. A solenoid valve is installed at the middle section of the discharge port, and spiral fins are fixed on the outer side of the inner shell.
[0010] The vessel lid is detachably installed on the top of the inner shell, and feed inlets are fixed on both sides of the top of the vessel lid. A pressure gauge is installed on one side of the top of the vessel lid.
[0011] An electromagnetic coupler is installed inside the top of the insulation shell, and a drive motor is installed at the top of the electromagnetic coupler. A soft starter is installed on one side of the drive motor, and a stirring rod is connected to the bottom of the electromagnetic coupler.
[0012] The cleaning structure, located on the outside of the stirring rod, is used to clean the inner wall of the inner shell while stirring;
[0013] An anti-reverse structure is installed inside the feed inlet. The anti-reverse structure includes a retaining ring fixed to the bottom of the feed inlet, a movable plate installed at the bottom of the retaining ring, a rubber ring fixed to the top of the movable plate, and a guide component installed at the top of the rubber ring.
[0014] The above technical solution provides a constant temperature environment for the reaction through an insulation shell. The inlet and outlet are responsible for adding reactants and discharging products, respectively. The pressure changes inside the reactor are monitored in real time by a pressure gauge. The drive motor drives the stirring rod to rotate through an electromagnetic coupler to achieve uniform mixing of reactants. The soft starter ensures smooth motor start-up and reduces the impact on the system.
[0015] Furthermore, the guide assembly includes a limiting frame fixed inside the top of the feed inlet, a slide rod slidably connected inside the limiting frame and connected to the moving plate, and a return spring installed between the limiting frame and the moving plate.
[0016] The above technical solution uses the overflowing reactants to push the moving plate upward, causing it to close with the retaining ring and effectively seal the feed inlet. At the same time, the return spring extends and deforms to prepare for subsequent reset.
[0017] Furthermore, the slide rod and the limiting frame form a sliding structure, and the slide rod and the limiting frame form a telescopic structure through the return spring.
[0018] Through the above technical solution, the slide bar slides within the limiting frame and is controlled by the return spring to extend and retract, which allows the moving plate to respond flexibly to pressure changes and achieve rapid sealing.
[0019] Furthermore, the frontal cross-section of the retaining ring has a funnel-shaped inclined structure, and the inner diameter of the retaining ring is smaller than the outer diameter of the moving plate.
[0020] The above technical solution ensures that the moving plate can fit tightly against the retaining ring under pressure, enhancing the sealing effect and effectively preventing backflow.
[0021] Furthermore, the cleaning structure includes a connecting frame fixed to the outside of the stirring rod, a rotating frame rotatably connected to the inside of both sides of the connecting frame, a scraper fixed to one side of the rotating frame, and a spring plate fixed to one side of the rotating frame and connected to the connecting frame.
[0022] The above technical solution utilizes the rotation of the stirring rod to drive the connecting frame to rotate, causing the scraper to move on the inner wall of the inner shell, effectively cleaning the inner wall of the inner shell.
[0023] Furthermore, when the scraper contacts the inner shell, the spring sheet is in a bent state, and a sliding structure is formed between the scraper and the inner shell.
[0024] Through the above technical solution, the scraper adheres tightly to the inner wall of the inner shell under the action of the spring plate, thereby improving the cleaning effect.
[0025] The above-described solution of this utility model has at least the following beneficial effects:
[0026] This invention utilizes overflowing reactants to push a moving plate upwards, causing it to close with a baffle ring and effectively seal the feed inlet. This achieves the anti-backflow function of the device, effectively preventing reactant backflow, ensuring the stability and safety of the reaction process, and simultaneously helping to maintain stable pressure and temperature inside the reactor, thereby improving reaction efficiency.
[0027] This invention utilizes the rotation of the stirring rod to drive the connecting frame to rotate as well, causing the scraper to move along the inner wall of the inner shell and effectively clean the inner wall. This achieves the inner wall cleaning function of the device, ensuring the cleanliness and hygiene of the inside of the reactor, preventing residues from contaminating or interfering with subsequent reactions, and thus guaranteeing the accuracy and purity of the reaction.

[0034] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0035] like Figures 1 to 4 As shown, an embodiment of this utility model provides a soft-drive magnetically coupled high-temperature and high-pressure reactor, including an insulation shell 1, and further comprising:
[0036] Liquid inlet 12 is installed on one side of the bottom end of the insulation shell 1, and a support frame 13 is fixed at the bottom end of the insulation shell 1.
[0037] The inner shell 14 is fixed inside the insulation shell 1, and a discharge port 11 is fixed at the bottom of the inner shell 14. A solenoid valve 10 is installed at the middle section of the discharge port 11, and a spiral fin 15 is fixed on the outer side of the inner shell 14.
[0038] The lid 2 is detachably installed on the top of the inner shell 14, and the two sides of the top of the lid 2 are fixed with feed inlets 8, and a pressure gauge 3 is installed on one side of the top of the lid 2.
[0039] An electromagnetic coupler 6 is installed inside the top of the insulation shell 1, and a drive motor 5 is installed at the top of the electromagnetic coupler 6. A soft starter 4 is installed on one side of the drive motor 5, and a stirring rod 16 is connected to the bottom of the electromagnetic coupler 6.
[0040] The cleaning structure 9 is located on the outside of the stirring rod 16 and is used to clean the inner wall of the inner shell 14 while stirring.
[0041] The anti-reverse structure 7 is installed inside the feed inlet 8. The anti-reverse structure 7 includes a retaining ring 703 fixed to the bottom of the feed inlet 8, a movable plate 701 installed at the bottom of the retaining ring 703, a rubber ring 702 fixed to the top of the movable plate 701, and a guide component installed at the top of the rubber ring 702.
[0042] In this embodiment of the invention, the heat-insulating shell 1 provides a constant temperature environment for the reaction, while the liquid inlet 12 facilitates the introduction of cold or hot water into the interior of the heat-insulating shell 1 to adjust the reaction temperature. The spiral fins 15 enhance the heat exchange efficiency of the inner shell 14. The feed inlet 8 and the discharge outlet 11 are responsible for the addition of reactants and the discharge of products, respectively. The solenoid valve 10 equipped with the discharge outlet 11 can precisely control the outflow of products. The pressure gauge 3 monitors the pressure changes inside the reactor in real time. The drive motor 5 drives the stirring rod 16 to rotate through the electromagnetic coupler 6 to achieve uniform mixing of reactants. The soft starter 4 ensures the smooth start of the motor and reduces the impact on the system.
[0043] like Figure 4 As shown, the guide assembly includes a limiting frame 704 fixed inside the top of the feed inlet 8, a slide rod 705 slidably connected inside the limiting frame 704 and connected to the moving plate 701, and a return spring 706 installed between the limiting frame 704 and the moving plate 701. The slide rod 705 and the limiting frame 704 form a sliding structure, and the slide rod 705 and the limiting frame 704 form a telescopic structure through the return spring 706. The front view cross-section of the retaining ring 703 is a funnel-shaped inclined structure, and the inner diameter of the retaining ring 703 is smaller than the outer diameter of the moving plate 701.
[0044] In this embodiment of the invention, when the internal pressure of the device is too high, the reactants will generate an upward thrust, thereby pushing the moving plate 701 upward. As the moving plate 701 rises, it will gradually close with the retaining ring 703 to form a tight sealing surface, thereby effectively sealing the feed port 8 and preventing the reactants from flowing back. During this process, the reset spring 706 will stretch and deform due to the rise of the moving plate 701 to store energy and prepare for subsequent reset. The rubber ring 702 is sandwiched between the moving plate 701 and the retaining ring 703, further enhancing the sealing effect.
[0045] like Figure 3 As shown, the cleaning structure 9 includes a connecting frame 903 fixed to the outside of the stirring rod 16, a rotating frame 902 rotatably connected to the inside of both sides of the connecting frame 903, a scraper 901 fixed to one side of the rotating frame 902, and a spring plate 904 fixed to one side of the rotating frame 902 and connected to the connecting frame 903. When the scraper 901 contacts the inner shell 14, the spring plate 904 is in a bent state, and a sliding structure is formed between the scraper 901 and the inner shell 14.
[0046] In this embodiment of the invention, the rotation of the stirring rod 16 causes the connecting frame 903 to rotate as well, causing the scraper 901 to move on the inner wall of the inner shell 14. At the same time, the bent spring plate 904 pushes the rotating frame 902 to rotate around the connecting frame 903, so that the rotating frame 902 drives the scraper 901 to stick tightly to the inner wall of the inner shell 14, thereby achieving effective cleaning of the inner wall of the inner shell 14 while stirring.
[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
