Description

Technical Field

[0001] The invention relates to the technical field of extraction devices, and in particular to an organic extraction device for preparing organic framework materials. Background Art

[0002] Organic framework materials are porous crystalline materials formed by organic molecules connected by covalent bonds, including metal-organic framework materials, covalent organic framework materials, and some other derivative materials. In the process of preparing organic framework materials, the required organic molecules need to be extracted from the raw materials. Currently, the required organic molecules are separated by extraction by utilizing the difference in solubility of the substance in two solutions.

[0003] When performing liquid-liquid extraction, a turntable extraction tower is widely used in industry due to its advantages such as high efficiency, flexibility, energy saving and environmental protection. The centrifugal force generated by the rotating turntable is used to throw the organic phase and the extractant into droplets to increase the mixing speed of the two solutions, thereby improving the extraction effect. However, the existing turntable extraction tower has a limitation during use: the position of the turntable cannot be changed, resulting in the area of ​​the solution flow path in the tower remaining unchanged, which makes the shear force generated by the solution during the flow relatively stable, and thus makes the volume of the droplets generated by the solution during the flow process relatively stable. When the content of organic components in the solution is relatively high, the proportion of organic components in the formed droplets is unbalanced with the proportion of the extractant, thereby reducing the contact probability between the organic components and the extractant, resulting in a decrease in mass transfer efficiency, so that the organic components in the organic phase cannot be completely extracted, and then some organic matter is discharged together with the organic phase, resulting in a waste of organic components. Summary of the invention

[0004] In order to overcome the disadvantage that the flow rate of the solution in the existing rotary disc extractor cannot be adjusted during use, the present invention provides an organic extraction device for preparing an organic framework material.

The second connecting ring is internally rotatably connected to a second rotating ring, and the second rotating ring is fixed to the adjacent second driving rods, and the two first driving rods respectively pass through the adjacent second rotating rings.

[0007] It is further explained that the distance moved by the telescopic end of the first electric push rod is less than the minimum height difference between the first turntable and the adjacent fixed ring, and the distance moved by the telescopic end of the second electric push rod is twice the distance moved by the telescopic end of the first electric push rod.

[0008] It is further explained that the length of the connecting shell is not less than the distance moved by the telescopic end of the second electric push rod, so as to ensure that the first telescopic shell and the adjacent second telescopic shell are always in a sealed state.

[0009] It is further explained that a plurality of guide holes are disposed on the first turntable and the second turntable, and the guide holes on the first turntable and the adjacent second turntable are symmetrically distributed.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0019] The present invention provides an organic extraction device for preparing organic framework materials, such as Figure 1-10As shown, it includes: an extraction tank 1, which is provided with two upper and lower feed ports and two upper and lower discharge ports, a concentration detector is provided in the upper feed port, and fixed rings distributed in a linear array are installed in the extraction tank 1. The specific number of the fixed rings can be specifically selected by the staff, but it should be noted that the specific number of the fixed rings needs to be one more than the specific number of the first telescopic shell 3; a fixed shell 2, which is rotatably connected to the extraction tank 1, and a driving module for driving the fixed shell 2 to rotate is provided on the lower side of the extraction tank 1. The driving module is an existing device, and the figure shows a motor, a reducer and a bevel gear set as an example, wherein the motor and the reducer are both fixedly connected to the extraction tank 1, and the output shaft of the motor is fixedly connected to the input shaft of the reducer, and the two bevel gears in the bevel gear set are respectively fixedly connected to the output shaft of the reducer and the lower end of the fixed shell 2; the first telescopic shell 3 and the second telescopic shell 5 , each has a plurality of them, each of which is embedded in the interior of the fixed shell 2; the first turntable 4, the number of which is consistent with the number of the first telescopic shells 3, is limitedly slidably connected to the fixed shell 2, and the telescopic portion of the first telescopic shell 3 is fixedly connected to the adjacent first turntable 4; the second turntable 6, the number of which is consistent with the number of the second telescopic shells 5, is limitedly slidably connected to the fixed shell 2, and the telescopic portion of the second telescopic shell 5 is fixedly connected to the adjacent second turntable 6, all the second turntables 6 are staggered with all the first turntables 4, and all the second turntables 6 and all the first turntables 4 are staggered with the fixed ring of the linear array, the second telescopic shell 5 and the telescopic portion of the adjacent first telescopic shell 3 are slidably connected with a connecting shell 7, and a tension spring is fixedly connected between the connecting shell 7 and the two; a separation component is arranged in the extraction tank 1, and the separation component is used to change the relative position of the first turntable 4 and the second turntable 6.

[0020] In the above scheme, the concentration detector is arranged in the feed port for conveying the stock solution. In this article, the stock solution is conveyed at the upper feed port, that is, the stock solution is used as the continuous phase and the extractant is used as the dispersed phase. The concentration detector is used to detect the content of organic components in the stock solution, and the concentration detector is an existing device, which is not shown in the figure; the specific number of the first telescopic shell 3, the first turntable 4, the second telescopic shell 5, the second turntable 6 and the connecting shell 7 can be selected by the staff according to actual needs during production. The figure and the text are shown as eight examples, and the above parts are divided into a group of four on the upper side and a group of four on the lower side. There are two groups, one above the other, and the same parts of the two groups are symmetrically distributed up and down; in this article, "the first telescopic shell 3 and the adjacent second telescopic shell 5" refers to the first telescopic shell 3 and the second telescopic shell 5 located between two adjacent fixing rings, and the descriptions of the adjacent parts on the other parts are all parts between the two adjacent fixing rings unless otherwise specified; the four first turntables 4 on the lower side are respectively located below the adjacent second turntables 6, and the four first turntables 4 on the upper side are respectively located above the adjacent second turntables 6, and the connecting shell 7 is always located in the middle of the adjacent first telescopic shell 3 and the second telescopic shell 5 under the action of the two tension springs thereon, so as to block the gap between the telescopic parts of the two.

[0021] The working principle of the above scheme is as follows: the staff connects the conveying devices of the two solutions (stock solution and extractant) to the upper and lower feed ports respectively, the continuous phase flows downward through the upper feed port, and the dispersed phase flows upward through the lower feed port, so that the two solutions flow relative to each other to perform the extraction operation. At the same time, in the process of conveying the solution, the staff starts the driving module, and the driving module drives the fixed shell 2 to rotate, and the fixed shell 2 drives the eight first turntables 4 and the eight second turntables 6 thereon to rotate synchronously, stirring the solution in the extraction tank 1, and at the same time, centrifugal force is used to throw out the solution in contact with the first turntable 4 and the second turntable 6, so that the solution is dispersed into small droplets, and the mixing of the two solutions is accelerated, and the continuous phase after extraction is discharged through the discharge port on the lower side of the extraction tank 1, and the dispersed phase carries the required organic components and is discharged through the upper discharge port of the extraction tank 1.

[0022] During the above extraction process, if the concentration of the organic component in the stock solution increases, the value detected by the concentration detector increases continuously until the value detected by the concentration detector increases to a certain value, and the remote control terminal controls the separation component, and the separation component drives the four first telescopic shells 3 on the upper side to move upward, and the four first telescopic shells 3 on the lower side to move downward, shortening the distance between the upper side surface of the first telescopic shell 3 on the upper side and the adjacent fixed ring, thereby reducing the flow area between the upper four first rotating disks 4 and the adjacent fixed rings, increasing the speed of the stock solution when flowing through the gap between the upper four first rotating disks 4 and the adjacent fixed rings, and thus making the stock solution generate a higher shear force when flowing, increasing the dispersion of the stock solution droplets, and guiding the stock solution to the extractant located in the liquid in the two fixed rings (the adjacent fixed rings divide the cavity in the extraction tank 1 into multiple chambers, and the continuous phase and the extractant in the extraction tank 1 are relatively layered in each chamber when flowing, that is, the stock solution is mainly located in the lower part of each chamber, and the extractant is mainly located in the upper part of each chamber), increasing the mixing speed of the stock solution and the extractant, and improving the mass transfer efficiency.

[0023] During the downward movement of the four first telescopic shells 3 on the lower side, the distance between the lower side surface of the lower first turntable 4 and the adjacent fixed rings is synchronously reduced, thereby increasing the speed of the extractant in the extraction tank 1 when flowing through the gap between the four lower first turntables 4 and the adjacent fixed rings, thereby causing the extractant to generate a higher shear force when flowing, increasing the dispersion of the extractant droplets, and guiding the extractant to the continuous presence of the liquid in the two fixed rings, increasing the mixing rate of the stock solution and the extractant, improving the mass transfer efficiency, and thereby increasing the proportion of the extracted portion of the organic components in the stock solution, thereby improving the extraction effect and avoiding the extractant being unable to completely extract the organic components in the stock solution, resulting in a waste of resources.

[0024] Meanwhile, in the process of the separation component driving the first telescopic shell 3 to move, the separation component drives the second telescopic shell 5 to move synchronously, thereby driving the four second turntables 6 on the upper side to move upward and the four second turntables 6 on the lower side to move downward.

[0025] Until the eight first telescopic shells 3 are moved to the limit position, when the value detected by the concentration detector continues to increase, the remote control terminal controls the separation component, and the separation component drives the eight second telescopic shells 5 to move (the four second telescopic shells 5 on the upper side respectively drive the adjacent second turntables 6 to move downward, and the four second telescopic shells 5 on the lower side respectively drive the adjacent second turntables 6 to move upward), that is, the distance between the second turntable 6 and the adjacent first turntable 4 is changed, thereby shortening the distance between the lower side surfaces of the four second turntables 6 on the upper side and the adjacent fixed rings on the lower side, and synchronously shortening the distance between the upper side surfaces of the four second turntables 6 on the lower side and the adjacent fixed rings, reducing the flow area between the second turntable 6 and the adjacent fixed rings, increasing the speed of the two solutions (stock solution and extractant) when flowing through the gap between the second turntable 6 and the adjacent fixed rings, further increasing the dispersion of the droplets of the two solutions, improving the mass transfer efficiency, and thus improving the extraction effect.

[0026] During the working process of the above-mentioned parts, the remote control terminal can specifically change the positions of the eight first turntables 4 and the eight second turntables 6 according to the values ​​detected by the concentration detector. When the values ​​detected by the concentration detector begin to recover, the remote control terminal controls the separation component to synchronously reset the eight first telescopic shells 3 and the eight second turntables 6 to the initial position.

[0027] After the device has been working for a period of time, or after the solution has been extracted using the device, the staff stops supplying the solution into the extraction tank 1 and shuts down the drive module. The staff then releases the remaining solution in the extraction tank 1 and cleans and maintains the extraction tank 1 and its parts for subsequent use.

[0028] Further, the separation assembly includes: a first driving rod 8, having two symmetrically distributed, both of which are slidably connected to the fixed shell 2, and the two first driving rods 8 are respectively fixed to the telescopic ends of the adjacent first telescopic shells 3; a first electric push rod 9, the number of which is consistent with the number of the first driving rods 8, and both are fixed to the extraction tank 1; a first connecting ring 10, the number of which is consistent with the number of the first electric push rods 9, and is respectively fixed to the telescopic ends of the adjacent first electric push rods 9, and the first connecting ring 10 is internally rotatably connected to the first rotating ring 11, and the first rotating ring 11 is fixed to the adjacent first driving rod 8; a second driving rod 111, having two symmetrically distributed , are all slidably connected to the fixed shell 2, the two second driving rods 111 are respectively fixedly connected to the telescopic ends of the adjacent second telescopic shells 5; the second electric push rods 112, the number of which is consistent with the number of the second driving rods 111, are all fixedly connected to the first connecting ring 10; the second connecting rings 113, the number of which is consistent with the number of the second electric push rods 112, are respectively fixedly connected to the telescopic ends of the adjacent second electric push rods 112, the second connecting ring 113 is internally rotatably connected with the second rotating ring 114, the second rotating ring 114 is fixedly connected to the adjacent second driving rods 111, and the two first driving rods 8 respectively pass through the adjacent second rotating rings 114.

[0029] In the above scheme, the first driving rod 8, the first electric push rod 9, the first connecting ring 10, the first rotating ring 11, the second driving rod 111, the second electric push rod 112, the second connecting ring 113 and the second rotating ring 114 are all two symmetrically distributed up and down; the upper first driving rod 8 is fixedly connected to the telescopic ends of the four first telescopic shells 3 on the upper side, and the lower first driving rod 8 is fixedly connected to the telescopic ends of the four first telescopic shells 3 on the lower side; the upper second driving rod 111 is fixedly connected to the telescopic ends of the four second telescopic shells 5 on the upper side, and the lower second driving rod 111 is fixedly connected to the telescopic ends of the four second telescopic shells 5 on the lower side.

[0030] The working principle of the above scheme is as follows: when the above remote control terminal controls the terminal separation component to work, the remote control terminal first controls the two first electric push rods 9 to work, so that the telescopic ends of the two first electric push rods 9 move toward each other, that is, the telescopic end of the lower first electric push rod 9 moves downward, and the telescopic end of the upper first electric push rod 9 moves upward. The following is described by taking the movement of the lower first electric push rod 9 as an example: The telescopic end of the first electric push rod 9 drives the first connecting ring 10 on the lower side to move downward, and the first connecting ring 10 drives the first rotating ring 11 on the lower side to move downward synchronously, and then the first rotating ring 11 drives the telescopic parts of the four first telescopic shells 3 on the lower side to move downward through the transmission of the first driving rod 8 on the lower side, so that the telescopic parts of the four first telescopic shells 3 on the lower side are synchronously retracted into their fixed parts, thereby changing the positions of the four first turntables 4 on the lower side, and at the same time, the first connecting ring 10 on the lower side drives the fixed part of the second electric push rod 112 on the lower side to move downward, and the second electric push rod 112 drives the second rotating ring 114 on the lower side to move downward synchronously through the transmission of the second connecting ring 113 on the lower side when moving downward, and the second rotating ring 114 drives the telescopic parts of the four second telescopic shells 5 on the lower side to move downward synchronously through the transmission of the second driving rod 111 on the lower side, and the telescopic part of the second telescopic shell 5 is pulled out, and the telescopic part of the second telescopic shell 5 drives the adjacent second turntable 6 to move downward synchronously, until the telescopic end of the first electric push rod 9 on the lower side is fully extended, and the above parts move downward to the limit position.

[0031] When the upper remote control terminal controls the separation component to change the position of the eight second turntables 6, the remote control terminal controls the telescopic ends of the two second electric push rods 112 to extend synchronously, that is, the telescopic end of the upper second electric push rod 112 extends downward, and the telescopic end of the lower second electric push rod 112 extends upward. The following is described using the movement process of the telescopic end of the lower second electric push rod 112 as an example: the telescopic end of the second electric push rod 112 drives the second rotating ring 114 on the lower side to move upward synchronously through the transmission of the lower second connecting ring 113, and the second rotating ring 114 drives the telescopic parts of the four second telescopic shells 5 on the lower side to move upward synchronously through the transmission of the lower second driving rod 111, so that the telescopic end of the second telescopic shell 5 retracts into its fixed part, and then the second telescopic shell 5 drives the adjacent second turntable 6 to move upward synchronously to increase the distance between the second turntable 6 and the adjacent first turntable 4.

[0032] During the movement of the telescopic part of the second telescopic shell 5, the distance between the telescopic part of the second telescopic shell 5 and the telescopic part of the adjacent first telescopic shell 3 continues to increase, so that the two tension springs on the same connecting shell 7 are synchronously stretched and force is stored. At the same time, under the action of the two tension springs, the connecting shell 7 is always located in the middle of the telescopic part of the adjacent first telescopic shell 3 and the telescopic part of the adjacent second telescopic shell 5, and the connecting shell 7 is always in contact with the telescopic part of the first telescopic shell 3 and the telescopic part of the adjacent second telescopic shell 5, so as to block the gap between the telescopic part of the adjacent first telescopic shell 3 and the telescopic part of the adjacent second telescopic shell 5.

[0033] During the rotation of the fixed shell 2, the fixed shell 2 drives the two first driving rods 8 and the two second driving rods 111 to rotate synchronously. The two first driving rods 8 respectively drive the adjacent first rotating rings 11 to rotate in the adjacent first connecting rings 10, and the two second driving rods 111 respectively drive the adjacent second rotating rings 114 to rotate in the adjacent second connecting rings 113.

[0034] Furthermore, the distance moved by the telescopic end of the first electric push rod 9 is smaller than the minimum height difference between the first turntable 4 and the adjacent fixed ring, thereby preventing the first turntable 4 from colliding with the fixed ring during movement, and at the same time ensuring that the first turntable 4 is not flush with the adjacent fixed ring when moving to the extreme position, thereby facilitating the flow of the solution, and the distance moved by the telescopic end of the second electric push rod 112 is twice the distance moved by the telescopic end of the first electric push rod 9, thereby ensuring that after the second turntable 6 moves synchronously with the adjacent first turntable 4, the second turntable 6 can still be moved to the extreme position driven by the second electric push rod 112.

[0035] Furthermore, the length of the connecting shell 7 is not less than the distance moved by the telescopic end of the second electric push rod 112, which is used to ensure that the first telescopic shell 3 and the adjacent second telescopic shell 5 are always in a sealed state to prevent the solution in the extraction tank 1 from leaking into the first telescopic shell 3 and the second telescopic shell 5.

[0036] Furthermore, a plurality of guide holes 12 are provided on the first turntable 4 and the second turntable 6, and the guide holes 12 on the first turntable 4 and the adjacent second turntable 6 are symmetrically distributed, and the guide holes 12 are composed of a frustum portion and a cylindrical portion that are interconnected, and the minimum diameter of the frustum portion is equal to the diameter of the cylindrical portion.

[0037] In the above scheme, the specific number of guide holes 12 can be specifically selected by the staff, and the conical parts of the two guide holes 12 symmetrically distributed up and down on the first turntable 4 and the adjacent second turntable 6 are located on the opposite sides of the two, and the cylindrical parts are located on the opposite sides of the two, and the diameter of the conical part of the same guide hole 12 away from its cylindrical end is larger than the diameter close to the cylindrical end.

[0038] In the above extraction process, when the two solutions (stock solution and extractant) flow to contact the second turntable 6 and the first turntable 4 respectively, the two solutions are not only thrown out by the centrifugal force generated by the rotation of the two solutions, but also guided by the guide holes 12 on the two solutions to flow vertically, thereby increasing the mixing speed of the two solutions, that is, accelerating the extraction speed.

[0039] Furthermore, it also includes: a plurality of guide shells 13 are installed on the first turntable 4 and the second turntable 6, and the guide shells 13 are provided with drainage ports. The number of the guide shells 13 is consistent with the number of the guide holes 12. The guide shells 13 on the first turntable 4 are connected with the adjacent guide holes 12 thereon, and the guide shells 13 on the second turntable 6 are connected with the adjacent guide holes 12 thereon. Convection holes 14 are provided on the guide shells 13, and the diameter of the convection holes 14 is smaller than the minimum diameter of the guide holes 12. At the same time, the center of the convection hole 14 and the center of the adjacent guide hole 12 are located on the same central axis. The convection hole 14 cooperates with the drainage ports on the adjacent guide shells 13 to divide the solution into horizontal and longitudinal jets.

[0040] In the above scheme, the guide shell 13 is provided with a drainage port in the horizontal direction, and the guide shell 13 on the second turntable 6 and the guide shell 13 on the adjacent first turntable 4 are respectively located on the opposite sides of the second turntable 6 and the adjacent first turntable 4, and the guide shell 13 and the convection hole 14 are used to guide the flow of the solution passing through the guide hole 12, so that in addition to the part of the solution that flows vertically along the convection hole 14 on the guide shell 13, a part of the solution that flows horizontally is also diverted under the action of the drainage port of the guide shell 13, generating a horizontal jet, thereby increasing the mass transfer area and mass transfer rate between the two solutions, and thereby increasing the extraction rate.

[0041] Specifically, it also includes: a plurality of guide plates 16 , which are respectively fixed to the adjacent first turntable 4 and the adjacent second turntable 6 , and the guide plates 16 are provided with inclined surfaces for guiding the flow of the solution in the extraction tank 1 .

[0042] In the above scheme, the specific number of guide plates 16 in each group can be specifically selected by the staff, the guide plates 16 on the four lower first turntables 4 are located on the lower side, and the guide plates 16 on the four upper first turntables 4 are located on the upper side; the guide plates 16 on the four lower second turntables 6 are located on the upper side, and the guide plates 16 on the four upper second turntables 6 are located on the lower side; the specific direction of the inclined surface on the guide plate 16 needs to be specifically selected by the staff according to the rotation direction of the fixed shell 2 to ensure that the guide plate 16 can guide the solution to the adjacent guide hole 12 during the rotation of the fixed shell 2; at the same time, when the guide plate 16 rotates with the fixed shell 2, the guide plate 16 will also push the solution to flow toward the inner wall of the extraction tank 1, further increasing the mixing speed of the two solutions, that is, accelerating the extraction speed of the organic components.

[0043] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and its improved conception, which should be covered by the protection scope of the present application.
