Abstract
Description
Technical Field
[0001] This utility model relates to the field of microchannel continuous flow reactor technology, and in particular to a simple scale receiver and distributor 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 receivers and distributors is an inevitable trend, improving the efficiency of laboratory personnel, reducing product loss, and increasing yield.
[0003] In routine experiments using microchannel devices, it is usually necessary to flush the pipeline 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. The graduated cylinder is a traditional instrument for measuring liquids, and it often needs to be replaced back and forth when collecting flushing agent and receiving products from the microchannel device. This operation is tedious, reduces work efficiency, and causes some product loss during the replacement process. Therefore, this application proposes a simple graduated receiving and dispensing device for microchannel reactors that can improve work efficiency and reduce losses. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a simple scale receiver / distributor for microchannel reactors that can improve working efficiency and reduce losses.

[0006] A clamping frame is fixedly installed on a bracket. Two separating funnels are clamped and fixed on the clamping frame. A connecting tube is inserted between the two separating funnels. A three-way valve is inserted at the top of each separating funnel. A nitrogen balloon connecting tube is provided on the three-way valve. The nitrogen balloon connecting tube is used to fix the nitrogen balloon and provide an anaerobic environment for the separating funnel.
[0007] A receiving bottle is placed below the separating funnel. A drain valve is fixedly installed at the bottom of the separating funnel, and the tube end of the drain valve is inserted into the mouth of the receiving bottle and in close contact with it.
[0008] Optionally, the connecting pipe is inclined, and the inclination angle of the connecting pipe is 10-40°.
[0009] Optionally, an inlet pipe is fixedly installed on the outer wall of one of the separating funnels, the inlet pipe being inclined and fixedly connected to an external infusion pipe.
[0010] Optionally, two measuring cups are placed on top of the base, and the measuring cups are positioned below the matching receiving bottle.
[0011] Optionally, the clamping frame is provided with a sleeve structure, the top end of the bracket passes through the sleeve structure and is movably connected to it, a knob is threaded on the sleeve structure, one end of the knob passes through the sleeve structure and is in close contact with the bracket.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects: by fixing the nitrogen balloon to the three-way valve through the nitrogen balloon connecting tube, an anaerobic environment can be provided for the separating funnel, expanding the applicability of the separator.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] Example
[0030] like Figure 1 As shown, this utility model proposes a simple graduated receiving and dispensing device for a microchannel reactor, comprising a base 1, a support 2 fixedly mounted on the top of the base 1, a clamping frame 4 fixedly mounted on the support 2, and two dispensing funnels 5 clamped and fixed on the clamping frame 4. A three-way valve 6 is engaged at the top of the dispensing funnels 5, and a nitrogen balloon connecting pipe 8 is fixedly mounted on the three-way valve 6, fixing the nitrogen balloon to the nitrogen balloon connecting pipe 8, thereby providing an anaerobic environment for the dispensing funnels 5, making the dispenser suitable for the extraction of aerobic and anaerobic substances, effectively improving its applicability; a drain valve is fixedly mounted at the bottom of the dispensing funnels 5. 10. A receiving bottle 11 is fitted onto the outlet end of the drain valve 10. The opening and closing of the outlet end is controlled by the drain valve 10. When the outlet end is opened, the extract in the separatory funnel 5 can enter the receiving bottle 11 for easy collection. When the separatory funnel 5 needs to be cleaned, the cleaning solution is injected into the separatory funnel 5. After cleaning, the receiving bottle 11 is removed to ensure that the cleaning solution inside the separatory funnel 5 can be drained into the measuring cup 3 without replacing the receiving bottle 11. This not only improves work efficiency but also solves the problem of waste caused by frequent replacement of the receiving bottle 11, effectively reducing losses.
[0031] like Figure 2 As shown, in order to facilitate the synchronous addition of liquid to the two separating funnels 5, a connecting pipe 12 is installed between the two separating funnels 5. The connecting pipe 12 is inclined, with an inclination angle of 10-40°, preferably 15°. This design has the following advantages: when one of the separating funnels 5 is fed, part of the liquid flows into the connecting pipe 12 and can then enter the other separating funnel 5 for synchronous addition of liquid to the two separating funnels 5. During this process, the connecting pipe 12 with a 15° inclination angle can accelerate the flow of liquid and ensure that the liquid can quickly enter the other separating funnel 5.
[0032] Furthermore, during the installation of the connecting tube 12, first insert one end of the connecting tube 12 into the opening on the outer wall of one of the separating funnels 5, and then insert the other end of the connecting tube 12 into the opening on the outer wall of the other separating funnel 5. After completing the installation of the connecting tube 12, fix the two separating funnels 5 on the clamping frame 4 to ensure that the connecting tube 12 can be stably installed between the two separating funnels 5.
[0033] Secondly, an inlet pipe 9 is fixedly installed on the outer wall of one of the separating funnels 5. The height of the contact point between the inlet pipe 9 and the separating funnel 5 is greater than the height of the highest point of the connecting pipe 12. When liquid enters the first separating funnel 5 from the inlet pipe 9, some liquid can enter the connecting pipe 12, ensuring that some liquid can be discharged into the second separating funnel 5, which facilitates the synchronous liquid addition process of the two separating funnels 5. The inlet pipe 9 is designed with a 15° inclination angle. When the external infusion pipeline is sleeved on the inclined inlet pipe 9, the probability of the external pipeline falling off the inlet pipe 9 can be reduced.
[0034] It is worth noting that the contact points of the connecting tube 12 and the two separating funnels 5 are all located above the highest point of the scale line on the outer wall of the separating funnel 5, so as to meet the maximum capacity of the separating funnel 5.
[0035] like Figure 2 As shown, to facilitate the adjustment of the height of the clamping frame 4, a sleeve structure is fixedly installed on the clamping frame 4. The top of the support 2 passes through the sleeve structure and is movably connected to it, ensuring that the clamping frame 4 can be adjusted up and down along the support 2. When installing the separating funnel 5, the height of the clamping frame 4 can be adjusted according to the specifications of the separating funnel 5. A knob is threaded on the sleeve structure. After the clamping frame 4 is adjusted to the specified height, the knob is turned to lock the sleeve structure onto the support 2, ensuring that the clamping frame 4 is fixed at the adjusted height and improving the stability of the separating funnel 5 after installation.
[0036] like Figure 1 , Figure 2 As shown, to facilitate inflation of the nitrogen balloon, a hollow glass stopper is provided at the bottom of the three-way valve 6. The glass stopper is inserted into the top opening of the separating funnel 5 to ensure that the three-way valve 6 can be stably installed at the top of the separating funnel 5. An exhaust pipe 7 is fixedly installed at the bottom of the three-way valve 6. When the exhaust pipe 7 is opened, the internal channel of the nitrogen balloon connecting pipe 8 is also open, and the internal channel of the glass stopper is closed. The gas supply pipe of the nitrogen inflation device is connected to the exhaust pipe 7 to inflate the nitrogen balloon, which improves the convenience of inflation of the nitrogen balloon.
[0037] like Figure 1 and Figure 2 As shown, it is worth noting that when performing anaerobic extraction, the receiving bottle 11 is installed at the bottom of the drain valve 10, and the nitrogen balloon is fixed on the nitrogen balloon connecting pipe 8 to ensure that the extract is in an anaerobic environment. When performing aerobic extraction, the receiving bottle 11 is removed, and the measuring cup 3 is placed below the drain valve 10 to receive the product.
[0038] In this embodiment, an external infusion pipe is first connected to the inlet pipe 9, and liquid is supplied to the inlet pipe 9 through an external infusion device. This allows the liquid to enter the separating funnel 5 connected to the inlet pipe 9. Since a connecting pipe 12 is installed between the two separating funnels 5, and this connecting pipe 12 is inclined with its highest point lower than the lowest point of the inlet pipe 9, some liquid can enter the other separating funnel 5, achieving simultaneous liquid addition to both funnels 5. A nitrogen balloon installed on the nitrogen balloon connecting pipe 8 provides an anaerobic environment for the separating funnels 5, ensuring that the separator is suitable for extracting both aerobic and anaerobic substances. This effectively expands its applicability. When the separating funnel 5 needs to be cleaned, the cleaning solution is injected into the separating funnel 5 through the inlet pipe 9 to clean the inner wall of the separating funnel 5. After cleaning, the receiving bottle 11 is removed, and the drain channel at the bottom of the separating funnel 5 is opened through the drain valve 10 to ensure that the cleaning solution can be drained into the measuring cup 3. During the liquid addition process, the two separating funnels 5 can be added simultaneously through the connecting pipe 12 to ensure that the extract product can enter the two receiving bottles 11 without replacing the receiving bottles 11. This not only improves work efficiency but also solves the problem of waste of extract caused by replacing the receiving bottles 11, effectively reducing losses.
[0039] 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.
