Description

Technical Field

[0001] This utility model belongs to the field of chemical experimental equipment technology, and in particular relates to a water separation device for the cyclization reaction of 3-cyclohexene-1-carboxaldehyde. Background Technology

[0002] A water separator is a key device used in chemical experiments to separate water from a reaction system. It is especially important in organic synthesis to improve reaction efficiency by physically separating water from the organic phase. Therefore, it is a very common and important experimental instrument in chemical laboratories. It also plays an important role in the cyclization reaction 3-cyclohexene-1-carboxaldehyde.

[0003] Chinese patent CN216320005U discloses a water separation device for the cyclization reaction of 3-cyclohexene-1-carboxaldehyde. The patent states that "this utility model provides a water separation device for the cyclization reaction of 3-cyclohexene-1-carboxaldehyde, comprising a first tail connector, a tail connecting pipe, an electric heating tube, a steam conduction pipe, an air inlet connector, a water separator, a condenser, a water separation valve, an air inlet pipe, and a negative pressure connector. The steam conduction pipe is located inside the electric heating tube. The air inlet connector is fixedly connected to the upper end of the water separator. A condenser is located inside the water separator. An air inlet pipe is connected to the lower end of the air inlet connector. The air inlet pipe and the condenser have a double-helix winding structure. The negative pressure connector is connected to the upper left side of the water separator and is connected to an external negative pressure device. The advantages of this utility model are: by heating the azeotropic vapor through the electric heating tube, the phenomenon of the reaction solvent being condensed and flowing back into the reaction flask after reaching the azeotropic temperature is avoided. The water separator has a simple structure, is easy to operate, and has a significant water separation effect."

[0004] However, existing technology is not very convenient for reading the liquid after water separation. During the condensation process of boiling steam, the water layer and the organic layer are briefly mixed due to droplet splashing or turbulence. It takes a long time for the liquid to stand still before it can be separated into layers again. This makes dynamic observation difficult and makes it impossible to drain the condensed liquid in time. Therefore, it is necessary to design a water separation device for the cyclization reaction of 3-cyclohexene-1-carboxaldehyde. Utility Model Content

[0005] This invention provides a water separation device for the cyclization reaction of 3-cyclohexene-1-carboxaldehyde, aiming to solve the problem that some currently used water separation devices are inconvenient to read.

[0006] This invention is implemented as follows: a water separation device for the cyclization reaction of 3-cyclohexene-1-formaldehyde includes a water separator body; a discharge pipe fixedly connected to the bottom end of the water separator body, the discharge pipe being equipped with a water separation valve; a spherical exchange chamber fixedly connected to the top end of the water separator body, the top end of the spherical exchange chamber being fixedly connected to a condenser connector; a diversion pipe fixedly connected to the upper end of one side of the water separator body, one end of the diversion pipe and the condenser connector being fitted with a fixing ring, and a rubber sealing sleeve fixedly connected to the surface of the diversion pipe and the condenser connector at the bottom end of the fixing ring; an installation assembly mounted on the fixing ring, the installation assembly being used to install and remove the rubber sealing sleeve and the fixing ring; and an observation assembly mounted on the water separator body, the observation assembly allowing the user to more clearly observe the condensed liquid level.

[0007] Preferably, the observation assembly includes: a transparent observation box fixedly connected to the surface of the water distributor body, the bottom end of the transparent observation box being connected to the lower end of the water distributor body via a conduit; and stop blocks symmetrically fixedly connected to the lower end of the inner wall of the transparent observation box, the top end of the stop blocks being provided with a float plate.

[0008] Preferably, guide blocks are fixedly connected to both sides of the bottom wall of the transparent observation box, and the guide blocks are right-angled triangles.

[0009] Preferably, the inner wall of the transparent observation box is provided with a sliding groove, the inner bottom wall of the sliding groove is inclined, and the two sides of the float are fixedly connected with sliders that slide in cooperation with the inside of the sliding groove.

[0010] Preferably, the mounting assembly includes: a mounting groove formed inside one side of the fixing ring, a mounting block extending to the outside of the mounting groove being movably connected inside the mounting groove, a pull rod extending to the outside of the mounting groove being fixedly connected to one side of the mounting block; a mounting spring wound around the surface of the pull rod, the two ends of the mounting spring being fixedly connected to the inner wall of the mounting groove and one side of the mounting block, respectively; and a mounting hole formed at the lower end of one side of the diverter pipe.

[0011] Preferably, the inner wall of the mounting groove is provided with a limiting groove, and the two ends of one side of the mounting block are fixedly connected with limiting blocks that slide in cooperation with the inside of the limiting groove.

[0012] Preferably, one end of the mounting block forms an engaging structure with the interior of the mounting hole, and the length of the mounting block is less than the depth of the mounting groove.

[0013] Preferably, the rubber sealing sleeve is truncated cone-shaped, and the area of ​​the cross-section at the top of the rubber sealing sleeve is smaller than the area of ​​the cross-section of the fixing ring.

[0014] Preferably, a slot is provided on one side of the surface of the distributor pipe and the condenser connector, and a locking block is fixedly connected to the inner wall of the fixing ring to engage with the inside of the slot. The slot and the locking block are convex in shape.

[0015] Compared with related technologies, the water separation device for the cyclization reaction of 3-cyclohexene-1-carboxaldehyde provided by this utility model has the following beneficial effects: (1) The buoyancy of the condensate allows the float to slide up and down inside the transparent observation box. Since the bottom of the transparent observation box is located at the lower end of the water separator body, the boiling steam will not enter the transparent observation box and affect the observation of the liquid surface, thus ensuring the clarity of the liquid surface observation. At the same time, when the float descends to the top of the stop block, there is still a small amount of condensate above the water separator valve. At this time, the water separator valve should be closed in time to avoid the water separator valve not closing in time due to unclear observation, which may cause a small amount of other material in the water separator to be discharged together, thus improving its practicality.

[0016] (2) By using the engagement of the card block and the card slot, the rubber sealing sleeve and the fixing ring can be slidably fitted on the distributor pipe and the condenser pipe. At the same time, the installation component can be used to limit and fix the fixing ring after it is slidably fitted, thereby enabling the quick disassembly and assembly of the rubber sealing sleeve and the fixing ring. This facilitates the maintenance of the rubber sealing sleeve or the replacement of rubber sealing sleeves of different sizes to be used with beakers and condensers of different specifications, thus improving its applicability.

Detailed Implementation

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] Example 1 A preferred embodiment of the water separation device for the cyclization reaction 3-cyclohexene-1-carboxaldehyde provided by this invention is, for example... Figures 1 to 6 As shown: A water separation device for the cyclization reaction 3-cyclohexene-1-formaldehyde includes a water separator body 4; a drain pipe 6 fixedly connected to the bottom end of the water separator body 4, with a water separation valve 5 installed on the drain pipe 6; a spherical exchange chamber 2 fixedly connected to the top end of the water separator body 4, with a condenser connector 9 fixedly connected to the top end of the spherical exchange chamber 2; a diversion pipe 8 fixedly connected to the upper end of one side of the water separator body 4, with a fixing ring 10 fitted at one end of the diversion pipe 8 and the condenser connector 9, and a rubber sealing sleeve 1 fixedly connected to the surface of the diversion pipe 8 and the condenser connector 9 at the bottom end of the fixing ring 10; an installation component 7 assembled on the fixing ring 10, which is used to install and remove the rubber sealing sleeve 1 and the fixing ring 10; and an observation component 3 assembled on the water separator body 4, which allows the user to more clearly observe the condensed liquid level.

[0022] It should be noted that some existing water separation devices for the cyclization reaction of 3-cyclohexene-1-carboxaldehyde still have certain shortcomings in actual use. It is inconvenient to read the liquid after water separation because during the condensation process of boiling steam, the water layer and the organic layer are briefly mixed due to droplet splashing or turbulence. It needs to be left to stand for a long time before the layers can be separated again, which makes dynamic observation difficult and makes it impossible to drain the condensed liquid in time.

[0023] In this embodiment, the distributor pipe 8 is connected to the flask, and the condenser pipe 9 is connected to the condenser. The rubber sealing sleeve 1 ensures the sealing between the distributor pipe 8 and the flask and between the condenser pipe 9 and the condenser. During the water separation process, the observation component 3 can be used to clearly observe the condensate level inside the water separator body 4. When a certain amount is reached, the water separation valve 5 can be opened to discharge the condensate, thus realizing the water separation operation. At the same time, the installation component 7 can be used to remove and install the rubber sealing sleeve 1, which is convenient for the maintenance of the rubber sealing sleeve 1 or the replacement of rubber sealing sleeve 1 of different sizes to be suitable for flasks and condensers of different specifications.

[0024] In a further preferred embodiment of the present invention, the observation component 3 includes: a transparent observation box 301 fixedly connected to the surface of the water distributor body 4, the bottom end of the transparent observation box 301 being connected to the lower end of the water distributor body 4 via a conduit; and a stop block 305 symmetrically fixedly connected to the lower end of the inner wall of the transparent observation box 301, the top end of the stop block 305 being provided with a float plate 306.

[0025] In this embodiment, the condensed liquid drips onto the lower part of the water distributor body 4 and gradually rises. At this time, some of the condensate enters the transparent observation box 301 through the conduit. The buoyancy of the condensate causes the float 306 to slide upward inside the transparent observation box 301. Since the bottom of the transparent observation box 301 is located at the lower end of the water distributor body 4, boiling steam will not enter the transparent observation box 301 and affect the observation of the liquid level. When the condensate is discharged, the liquid level inside the transparent observation box 301 gradually decreases, causing the float 306 to descend. The right-angled triangular guide block 304 ensures that the condensate inside the transparent observation box 301 can be discharged more thoroughly. When the float 306 descends to the top of the stop block 305, there is still a small amount of condensate above the water distribution valve 5. At this time, the water distribution valve 5 is closed in time to avoid the water distribution valve 5 not closing in time due to unclear observation, which may cause a small portion of another material in the water to be discharged inadvertently.

[0026] In a further preferred embodiment of the present invention, guide blocks 304 are fixedly connected to both sides of the bottom wall of the transparent observation box 301, and the shape of the guide blocks 304 is a right triangle.

[0027] In this embodiment, the right-angled triangular guide block 304 is used to allow the condensate inside the transparent observation box 301 to be discharged more thoroughly.

[0028] In a further preferred embodiment of the present invention, a groove 302 is provided on the inner wall of the transparent observation box 301, the inner bottom wall of the groove 302 is inclined, and sliders 303 that slide and cooperate with the inside of the groove 302 are fixedly connected to both sides of the float plate 306.

[0029] In this embodiment, the sliding of the slider 303 inside the groove 302 is used to improve the stability of the up-and-down sliding of the float 306.

[0030] Example 2 Based on Example 1, a preferred embodiment of the water separation device for the cyclization reaction 3-cyclohexene-1-carboxaldehyde provided by this invention is, for example... Figures 1 to 6 As shown: The mounting assembly 7 includes: a mounting groove 705 formed inside one side of the fixing ring 10, a mounting block 706 extending to the outside of the mounting groove 705 is movably connected inside the mounting groove 705, and a pull rod 701 extending to the outside of the mounting groove 705 is fixedly connected to one side of the mounting block 706; a mounting spring 702 wrapped around the surface of the pull rod 701, with both ends of the mounting spring 702 fixedly connected to the inner wall of the mounting groove 705 and one side of the mounting block 706 respectively; and a mounting hole 703 formed at the lower end of one side of the diversion pipe 8.

[0031] In this embodiment, by pulling the pull rod 701, the mounting block 706 slides inside the mounting groove 705, compressing the mounting spring 702 until it is completely disengaged from the mounting hole 703. Then, the fixing ring 10 can be slidably removed from the surface of the distributor pipe 8 and the condenser connector 9. During installation, the pull rod 701 is first pulled to make the mounting block 706 slide. After the fixing ring 10 is slidably fitted onto the surface of the distributor pipe 8 and the condenser connector 9, the pull rod 701 can be released. Using the elastic force of the mounting spring 702, the mounting block 706 slides and locks into the mounting hole 703, achieving a firm and stable installation of the fixing ring 10.

[0032] In a further preferred embodiment of the present invention, a limiting groove 704 is provided on the inner wall of the mounting groove 705, and a limiting block 707 that slides and engages with the inside of the limiting groove 704 is fixedly connected to both ends of one side of the mounting block 706.

[0033] In this embodiment, the sliding stability of the mounting block 706 is improved by utilizing the sliding of the limiting block 707 inside the limiting groove 704.

[0034] In a further preferred embodiment of the present invention, one end of the mounting block 706 forms an engaging structure with the interior of the mounting hole 703, and the length of the mounting block 706 is less than the depth of the interior of the mounting groove 705.

[0035] In a further preferred embodiment of this utility model, the rubber sealing sleeve 1 is shaped like a frustum, and the area of ​​the cross-section at the top of the rubber sealing sleeve 1 is smaller than the area of ​​the cross-section of the fixing ring 10.

[0036] In this embodiment, a frustum-shaped rubber sealing sleeve 1 is used to facilitate smoother insertion into the beaker and condenser, thereby improving the sealing performance after insertion.

[0037] In a further preferred embodiment of the present invention, a slot 11 is provided on one side of the surface of the diverter pipe 8 and the condenser pipe 9, and a locking block 12 that engages with the inside of the slot 11 is fixedly connected to the inner wall of the fixing ring 10. The slot 11 and the locking block 12 are convex in shape.

[0038] In this embodiment, the engagement between the convex locking block 12 and the slot 11 enhances the stability of the sliding installation of the fixing ring 10 with the surface of the diversion pipe 8 and the condenser pipe 9.

[0039] In summary, the observation component 3 allows users to more clearly observe the liquid level inside the water distributor body 4, while the installation component 7 enables quick installation and removal of the rubber sealing sleeve 1.
