Description

Technical Field

[0001] This utility model relates to the field of microchannel continuous flow reactor technology, and in particular to an automatic liquid receiving device for microchannel reactors. Background Technology

[0002] Microchannel continuous flow reactors are widely used in chemical, pharmaceutical, and environmental protection fields. Microchemical systems enhance the rate and controllability of flow, mixing, and transfer processes within the system, shortening reaction and separation times, reducing material retention in the process, and minimizing byproduct formation. However, laboratory reactions require various processes, necessitating large amounts of organic solvents for pipeline flushing and the collection of wash liquids followed by product collection, leading to complex operations and reduced yields. Therefore, designing graduated dispensing devices is an inevitable trend to improve the efficiency of laboratory personnel, reduce product loss, and increase yield.

[0003] In routine experiments using microchannel devices, it is typically necessary to flush the tubing before and after the reaction, collect a certain amount of flushing agent, replace the receiving bottle, collect the product, and prepare for the next reaction. Traditional methods usually involve using a graduated cylinder to collect a certain amount of liquid; however, this process of collecting the microchannel device flushing agent and collecting the product often requires repeated replacements, which is cumbersome, reduces work efficiency, and causes some solvent loss during replacement, significantly decreasing the ease of use of the equipment. Therefore, this application proposes an automated liquid receiving device that simplifies operation and thereby improves work efficiency. Utility Model Content

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Example

[0031] like Figure 1 and Figure 2As shown, this utility model proposes an automatic liquid receiving device for a microchannel reactor, including a support frame 1. A storage plate 2 is movably mounted on the support frame 1. The storage plate 2 is adjustable in height. A horizontally arranged bracket on the support frame 1 supports the storage plate 2, preventing it from continuously sliding down and allowing it to be erected at a specified height. A drive assembly 6 is fixedly mounted on the top of the support frame 1, and a feeding pipe 4 is fixedly mounted on the drive assembly 6. The drive assembly 6 drives the feeding pipe 4 to perform circumferential movement, facilitating the adjustment of the feeding pipe 4's horizontal position. This allows for the feeding of multiple separating funnels 7 arranged below it without manual switching, making operation convenient. The multiple separating funnels 7 are all inserted into circular openings carved in the storage plate 2. Since the bottom diameter of the separating funnel 7 is smaller than its top diameter, when the bottom end of the separating funnel 7 is inserted into the circular opening... Its top diameter is larger than the inner diameter of the circular opening, so it will not fall downwards and can be stably mounted on the storage plate 2, making it easy to assemble and disassemble. The bottom of the aforementioned separating funnel 7 is fixedly installed with a four-way valve 72, and the bottom end of the four-way valve 72 is fixedly installed with a discharge pipe 73. The four-way valve 72 can control the opening and closing of the bottom pipe of the separating funnel 7. When the discharge pipe 73 is opened, the liquid in the separating funnel 7 can be discharged into the receiving bottle 8. The separating funnel 7 is also equipped with two conversion pipes 74, which are set on the same axis. The external hose is connected to the conversion pipe 74. When the separating funnel 7 needs to be cleaned, one of the conversion pipes 74 is opened, and the cleaning liquid can be discharged from the conversion pipe 74, preventing the cleaning liquid from being discharged into the receiving bottle 8 from the discharge pipe 73. Therefore, there is no need to move the receiving bottle 8, which effectively improves the cleaning efficiency.

[0032] like Figure 3 As shown, in order to achieve automatic liquid addition to multiple separating funnels 7, a drive assembly 6 is used to drive the feeding pipe 4. The drive assembly 6 includes a suspension 61, which is fixedly installed on the top of the support frame 1. A double connecting rod 62 is rotatably installed on the suspension 61, and two rotating plates 63 are fixedly installed on the double connecting rod 62. The two rotating plates 63 are rotatably connected as one unit through a double rotating shaft structure, and the two can make small-amplitude circumferential swaying. A pipe fixing plate 64 is rotatably installed at the ends of the two rotating plates 63. The feeding pipe 4 is fixedly installed at the end of the pipe fixing plate 64 away from the rotating plates 63. When the two rotating plates 63 make small-amplitude circumferential swaying, they can drive the pipe fixing plate 64 to rotate, and then drive the feeding pipe 4 to make circumferential movement, ensuring that the outlet end of the bottom of the feeding pipe 4 can be switched to the top of multiple separating funnels 7. Liquid addition to multiple separating funnels 7 can be completed without manual switching, which improves the convenience of liquid addition operation.

[0033] Furthermore, in order to improve the stability of the feeding pipe 4 in circular motion, a limiting plate 3 is fixedly installed on the support frame 1. The limiting plate 3 has a circular limiting opening 5. The feeding pipe 4 is set in the inner area of ​​the circular limiting opening 5. The circular limiting opening 5 limits the circular motion trajectory of the feeding pipe 4, effectively improving its stability during circular motion.

[0034] Secondly, in order to facilitate the control of the rotating plate 63 to shake, a servo motor is installed inside the suspension 61. The output end of the servo motor is fixedly connected to a single link structure in the double link 62. By driving the single link to rotate through the servo motor, it can be ensured that both rotating plates 63 can shake in a circular motion.

[0035] like Figure 3 As shown, when manual intervention is required as an alternative emergency plan, the feeding tube 4 needs to be manually switched. To improve the protection of the container, a wooden stopper 71 is fitted at the top of the separating funnel 7. A circular opening is cut into the wooden stopper 71. When the feeding tube 4 is moved above the circular opening, liquid can be added into the separating funnel 7. The wooden stopper 71 is suitable for manual switching of feeding operations. The operator manually inserts the feeding tube 4 into the wooden stopper 71 to avoid collision between the feeding tube 4 and the separating funnel 7, thereby improving the protection of the container.

[0036] like Figure 3 As shown, in order to reduce the content of by-products in the extract, a quenching reaction is used to remove impurities from the extract in the receiving bottle 8. Multiple magnetic stirrers 9 are placed inside the support frame 1, and the receiving bottle 8 is placed on top of the matching magnetic stirrer 9. The magnetic stirrer 9 drives the stirring rod inside the receiving bottle 8 to shake, which can stir the extract inside the receiving bottle 8, ensuring that the substances in the extract are mixed more evenly and avoiding the formation of impurities such as flocculants.

[0037] In this embodiment, the external infusion hose is first fixed to the top of the feeding pipe 4. The discharge rate of the external infusion pipe is controlled by a valve. When liquid needs to be added to the separating funnel 7, the liquid is injected into the separating funnel 7 through the feeding pipe 4. Since there are multiple separating funnels 7, when adding liquid to different separating funnels 7, the servo motor installed in the suspension 61 drives the rotating plate 63 to shake, which in turn drives the pipe fixing plate 64 and the feeding pipe 4 to perform circumferential motion. This makes it easy to adjust the feeding pipe 4 to be above the separating funnel 7 that needs to be added, without the need for manual adjustment. The feeding pipe 4 is switched and adjusted to achieve automated operation, saving time and improving liquid addition efficiency. When the separating funnel 7 needs to be cleaned, the cleaning solution is injected into the separating funnel 7, and the internal channel of the discharge pipe 73 is closed by the four-way valve 72. At this time, the internal channel of the switching pipe 74 is opened to ensure that the cleaning solution can be discharged from the switching pipe 74, preventing the cleaning solution from entering the receiving bottle 8. When cleaning the container, there is no need to replace the receiving bottle 8 or remove the separating funnel 7 from the device, which simplifies the operation steps of cleaning the container and effectively improves work efficiency.

[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
