Description

Technical Field

[0001] This utility model relates to the field of extraction device technology, specifically to a high-efficiency extraction and separation device for chemical engineering. Background Technology

[0002] A high-efficiency extraction and separation device for chemical engineering is a device specifically designed to achieve efficient separation and precise extraction of liquid mixtures. Based on chemical engineering principles and operating techniques, it utilizes the differences in solubility of different substances in solvents to separate the target substance from the mixture through a multi-stage extraction and separation process.

[0003] However, in existing extraction and separation technologies, when the mixture is placed inside the extraction flask and the separation process begins, the liquid level gradually rises as separation progresses. Once this liquid level exceeds the top of the siphon tube, the separated liquid is automatically discharged from the system according to the siphon principle. This mechanism is effective in most cases, but problems arise when the mixture accumulates above the top of the siphon tube—the portion of the mixture above the top of the siphon tube cannot be effectively extracted and separated because it cannot be reached by the siphon effect. This directly leads to a significant reduction in overall extraction efficiency. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work fall within the protection scope of the utility model.

[0026] In order to better understand the purpose, structure and function of the utility model, a kind of chemical engineering high-efficiency extraction separation device of the utility model will be further described in detail below with reference to the drawings.

[0027] Refer to Figure 1 And Figure 2 A kind of chemical engineering high-efficiency extraction separation device, including heating pot 1;The top of heating pot 1 is provided with flask 2, flask 2 is inserted with extraction bottle 3 in top portion, extraction bottle 3 is inserted with condenser 4 in top portion, soft conduit 5 is inserted between flask 2 and condenser 4, extraction bottle 3 is provided with stirring part 6 on surface, and extraction bottle 3 is provided with pressing part 7 in inside.

[0028] Refer to Figures 2-5The stirring component 6 includes a clamping sleeve 61 fitted onto the top of the extraction bottle 3. A fixing ring 62 is fixedly installed on the surface of the clamping sleeve 61, and a motor 63 is fixedly installed inside the fixing ring 62. A rotating ring 64 is arranged above the clamping sleeve 61. A belt is fitted between the motor 63 and the rotating ring 64. The belt is fitted onto the output shaft of the motor 63. After driving the motor 63, the rotating ring 64 is rotated through the belt. A support rod 65 is fixedly installed at the top of the clamping sleeve 61. A groove is opened at the bottom of the rotating ring 64. The top of the support rod 65 is slidably connected inside the groove, and the support rod 65 supports the rotating ring 64. This makes the rotation of the rotating ring 64 more stable. A stirring rod 66 is fixedly installed at the bottom of the rotating ring 64, and a stirring ring 67 is fixedly installed at the bottom of the stirring rod 66. A placement net 68 is fixedly installed at the bottom of the stirring ring 67. There are four stirring rods 66 distributed circumferentially. The stirring rods 66 agitate the mixture inside the extraction bottle 3, resulting in a higher extraction efficiency. The placement net 68 is located at the center of the bottom of the extraction bottle 3. The placement net 68 supports the mixture and prevents it from turning over too much and breaking during the agitation process, thereby preventing the mixture from leaking out of the filter bag and affecting the extraction efficiency.

[0029] Reference Figure 3 , Figure 4 and Figure 6 The pressing component 7 includes a placement plate 71 fixedly installed on the top of the support rod 65. A connecting block 72 is fixedly connected to the bottom end of the placement plate 71. A spring 73 is fixedly installed at the bottom end of the connecting block 72. A pressing block 74 is fixedly installed at the bottom end of the spring 73. A side groove 75 is formed on the surface of the pressing block 74. The side groove 75 is arranged in a ring on the surface of the pressing block 74. The horizontal height of each position in the side groove 75 is different. A protruding rod 76 is fixedly installed in the middle of the surface of one of the stirring rods 66. The bottom of the placement plate 71 extends through the rotating ring 64 into the interior of the extraction bottle 3. The top area of ​​the connecting block 72 is smaller than the bottom area. The protruding rod 76 and the side groove 75 are adapted to slide and connect. When the stirring rod 66 drives the protruding rod 76 to rotate, the protruding rod 76 will push the pressing block 74 to move up and down repeatedly, so that the pressing block 74 continuously presses the extracted mixture, so that the mixture is pressed down to the bottom of the siphon tube of the extraction bottle 3.

[0030] Working principle: the operator places the mixture inside the filter bag, and places the filter plate inside the extraction bottle 3. There are three inlets on the top of the flask 2. The extraction bottle 3 is inserted into the middle of the top of the flask 2. The soft tube 5 is inserted into the inlet on the right side of the flask 2. The condenser tube 4 is inserted into the top of the placement plate 71 and aligned with the center of the top of the extraction bottle 3. Then the end of the soft tube 5 away from the flask 2 is inserted into the top of the condenser tube 4. At this time, the assembly of various components is completed. Then the operator pours the solvent into the flask 2 through the inlet on the left side of the flask 2. Then the inlet on the left side of the flask 2 is plugged. At this time, the operator turns on the heating pot 1 to heat the solvent inside the flask 2. When the solvent inside the flask 2 reaches the boiling point, the solvent vaporizes and passes through the soft tube 5 and the condenser tube 4 in turn. When the vaporized solvent enters the inside of the condenser tube 4, it is re-liquefied and drips into the inside of the extraction bottle 3, thereby extracting the mixture inside the extraction bottle 3. When the liquid level of the extraction is higher than the highest point of the siphon tube of the extraction bottle 3, the extracted liquid will be discharged into the inside of the flask 2 through the siphon tube. At this time, continue to heat so that the liquid at the back is vaporized again into the inside of the extraction bottle 3. In this way, the extraction is repeated many times.

[0031] During the extraction process, the operator can drive the motor 63 to rotate the rotating ring 64. At this time, the rotating ring 64 rotates on the top of the support rod 65. Due to the support of the support rod 65, the rotation of the rotating ring 64 is stable. When the rotating ring 64 rotates, it will drive the stirring rod 66, the stirring ring 67 and the placement net 68 to rotate. The filter bag containing the mixture is placed on the top of the placement net 68, so that the mixture, the placement net 68 and the stirring rod 66 and the stirring ring 67 rotate together. The amplitude of the mixture turning over is small, so the mixture does not leak out of the filter bag. At this time, the rotation speed of the mixture is lower than that of the stirring ring 67 due to the resistance of the extraction liquid. Therefore, the stirring rod 66 and the stirring ring 67 stir the extracted mixture and the extraction liquid, so that the mixture located at the center of the accumulation can also be extracted, thereby improving the extraction efficiency.

[0032] During the extraction process, the solid volume of the mixture becomes smaller and smaller. When the stirring rod 66 rotates in the inside of the extraction bottle 3, it drives the convex rod 76 to rotate. The convex rod 76 slides in the inside of the side groove 75, thereby driving the pressing block 74 to move up and down reciprocally. At this time, the pressing block 74 will continuously press the mixture downward, so that the mixture is pressed to below the top end of the siphon tube of the extraction bottle 3, thereby completing the full extraction of the mixture.

[0033] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
