Description

[0002] Extraction is often used to separate and purify "liquid-liquid" solutions or emulsions, especially the purification of plant extracts. The principle of extraction is to perform separation operations based on the difference in solubility of the solute in the two phases, which is an interphase mass transfer process; the density of the two phases in the extraction is small, and the difference in interfacial tension is not large, so external energy such as stirring, pulsation, and vibration is required.

[0003] Existing vibration extraction towers are mostly driven by mechanical eccentric wheels, and a rigid coupling is used to directly connect the vibration shaft and the driving source. Due to processing errors, installation deviations or thermal deformation during operation, the vibration shaft is prone to radial deviation, causing the vibration screen plate to collide with the inner wall of the tower body, causing equipment damage. At the same time, the rigid connection of the traditional mechanical eccentric wheel drive mechanism cannot compensate for the slight deformation of the vibration shaft, resulting in the attenuation of vibration energy during the transmission process, affecting the extraction efficiency.

DETAILED DESCRIPTION

[0014] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0015] Example: Refer to Figure 1 and Figure 2 The present invention discloses a vibration extraction tower structure, comprising a vibration tower upper flange 1 and a vibration tower lower flange 2, wherein an extraction tower body 3 is fixedly connected between the vibration tower upper flange 1 and the vibration tower lower flange 2, and an inlet and outlet liquid pipeline assembly 4 is arranged on the outer side wall of the extraction tower body 3; The inlet and outlet liquid pipeline assembly 4 includes a heavy phase liquid inlet pipe 41 arranged on one side of the upper surface of the upper flange 1 of the vibration tower and a light phase liquid outlet pipe 42 arranged on one side of the outer wall of the connecting tube 5, a light phase liquid inlet pipe 43 is arranged on one side of the lower surface of the lower flange 2 of the vibration tower, and a heavy phase liquid outlet pipe 44 is arranged on the side of the lower surface of the lower flange 2 of the vibration tower away from the light phase liquid inlet pipe 43. The heavy phase liquid inlet pipe 41, the light phase liquid outlet pipe 42, the light phase liquid inlet pipe 43 and the heavy phase liquid outlet pipe 44 are all connected with the extraction tower body 3, and the outer walls of the heavy phase liquid inlet pipe 41, the light phase liquid outlet pipe 42, the light phase liquid inlet pipe 43 and the heavy phase liquid outlet pipe 44 are all provided with a control valve 17, and the top of the heavy phase liquid outlet pipe 44 is fixedly connected with a liquid level regulating pipe 18 connected with the heavy phase liquid inlet pipe 44, and the outer wall of the liquid level regulating pipe 18 is provided with a liquid level regulating valve 19; The control valves 17 respectively located on the outer side walls of the heavy phase liquid inlet pipe 41, the light phase liquid outlet pipe 42, the light phase liquid inlet pipe 43 and the heavy phase liquid outlet pipe 44 can respectively control the on-off of the liquid in the heavy phase liquid inlet pipe 41, the light phase liquid outlet pipe 42, the light phase liquid inlet pipe 43 and the heavy phase liquid outlet pipe 44, and then the relevant liquids can be controlled to enter and be discharged from the extraction tower body 3 by opening the control valves 17. When feeding, the control valves 17 of the heavy phase liquid inlet pipe 41 and the light phase liquid inlet pipe 43 are opened, and the heavy phase and light phase liquids respectively enter the extraction tower body 3 from the corresponding pipelines; When discharging, close the feed control valve, open the control valve 17 of the light phase liquid outlet pipe 42 and the heavy phase liquid outlet pipe 44, and the two-phase liquid flows out from the corresponding pipelines. Then, by controlling the opening and closing of the control valve 17, the flow rate and flow direction of the heavy phase and light phase liquid in and out of the extraction tower body 3 can be controlled to meet the feeding and discharging requirements of the extraction process and ensure the continuity and stability of the extraction process; When both the heavy phase liquid and the light phase liquid enter the extraction tower body 3, the position of the two-phase liquid interface in the extraction tower body 3 can be adjusted by the liquid level regulating valve 19. The height design of the liquid level regulating valve 19 can utilize the static pressure energy of the liquid to reduce the potential energy fluctuation when discharging the liquid, improve the flow stability, and avoid directly discharging the liquid in the extraction tower body 3 through the heavy phase liquid outlet pipe 44 from the extraction tower body 3 due to the potential energy fluctuation affecting the flow stability.

[0016] Reference Figure 1 and Figure 2 A connecting tube 5 is fixedly connected to the center of the upper surface of the upper flange 1 of the vibration tower. An opening 6 is opened at the center of the upper surface of the upper flange 1 of the vibration tower. A vibration shaft 7 is slidably connected in the opening 6. A vertically evenly distributed vibration screen plate 8 is fixedly connected to one side of the outer wall of the vibration shaft 7 located inside the extraction tower body 3. A driving component 9 for driving the vibration shaft 7 to vibrate is arranged at the top of the vibration shaft 7.

[0017] Reference Figure 1 , Figure 3 and Figure 4 The driving assembly 9 includes a driving motor 91, a sleeve 92 is fixedly mounted on the output end of the driving motor 91, a first top screw hole 14 is opened on one side of the outer wall of the sleeve 92, an eccentric wheel 93 is fixedly connected to one end of the sleeve 92 away from the driving motor 91, an eccentric shaft 94 is fixedly connected to one side of the outer wall of the eccentric wheel 93 away from the eccentric wheel sleeve 92, a rolling bearing 95 is rotatably connected to the outer wall of the eccentric shaft 94, a connecting rod 96 is fixedly connected to one side of the outer wall of the rolling bearing 95, and an anti-deflection connecting member 10 is provided between the connecting rod 96 and the vibration shaft 7; When the driving motor 91 is started, the output shaft rotates to drive the sleeve 92 and the eccentric wheel 93 to rotate. When the eccentric wheel 93 rotates, the eccentric shaft 94 moves in a circle along the center of the eccentric wheel 93, and the connecting rod 96 swings through the rolling bearing 95. The swing of the connecting rod 96 is transmitted to the vibration shaft 7 through the anti-deflection connecting piece 10.

[0018] Reference Figure 2 and Figure 4 The anti-deflection connecting member 10 includes a first connecting sleeve 101 fixedly mounted on an end of the connecting rod 96 away from the rolling bearing 95 and a second connecting sleeve 102 fixedly mounted on the top of the vibration shaft 7. A second top screw hole 15 is provided on one side of the outer wall of the first connecting sleeve 101, and a third top screw hole 16 is provided on one side of the outer wall of the second connecting sleeve 102. A universal joint 103 is fixedly connected between the first connecting sleeve 101 and the second connecting sleeve 102; The swing of the connecting rod 96 is transmitted to the first connecting sleeve 101, and then the motion is transmitted to the second connecting sleeve 102 through the universal joint 103, driving the vibration shaft 7 to vibrate, and then driving the vibration screen plate 8 fixed on the vibration shaft 7 to vibrate up and down in the extraction tower body 3, interacting with the heavy phase and light phase liquid flowing in the extraction tower body 3, and the vibration breaks the liquid boundary layer, reduces the mass transfer resistance, improves the mass transfer coefficient, accelerates the transfer of solutes between the two phases, and realizes efficient extraction; During the vibration process, if the vibration shaft 7 is laterally offset due to the impact of liquid flow or its own deformation, the universal joint 133 converts the lateral component force into rolling resistance in the joint through the rolling friction characteristics of its joint rolling bearing, rather than directly acting on the vibration shaft 7, thereby eliminating the influence of the lateral tension on the stability of the shaft system and eliminating the lateral tension. At the same time, the universal joint 133 forms a dynamic centering effect during the vibration process. Under the action of the vibration axial force, its joint rolling bearing always tends to maintain the minimum resistance motion path, that is, automatically corrects the slight deflection of the vibration shaft 7 to keep it coaxial with the tower body axis, thereby minimizing the deflection of the vibration shaft 7 due to uneven force and motion deviation, thereby minimizing the stability of the vibration extraction process and the extraction effect.

[0019] Reference Figure 2 and Figure 5 A bottom sleeve 11 is provided at the center of the upper surface of the lower flange 2 of the vibration tower, the bottom end of the vibration shaft 7 is slidably connected to the bottom sleeve 11, a liquid guide groove 12 is provided at the bottom end of the outer wall of the vibration shaft 7, and a linear bearing 13 adapted to the vibration shaft 7 is fixedly connected to the upper surface of the connecting tube 5; When in use, the bottom sleeve 11 and the linear bearing 13 provide support and guidance for the bottom and top ends of the vibration shaft 7 respectively. At the same time, when the vibration shaft 7 slides up and down in the linear bearing 13 and the bottom sleeve 11, the liquid in the bottom sleeve 11 can be discharged from the bottom sleeve 11 through the liquid guide groove 12, thereby minimizing the axial suction and drag force caused by the excessive tightness between the vibration shaft 7 and the bottom sleeve 11, making it easier for the bottom of the vibration shaft 7 to enter and exit the bottom sleeve 11, thereby reducing the load on the drive motor 91.

[0020] The workflow of the present invention is: Before use, screw the top screws into the first top screw hole 14, the second top screw hole 15, and the third top screw hole 16 respectively. Through the tightening force of the top screws, the shaft sleeve 92 and the output shaft of the drive motor 91, the first connecting sleeve 101 and the connecting rod 96, and the second connecting sleeve 102 and the vibration shaft 7 are firmly connected. During the operation of the equipment, the top screws continue to provide a tightening force to prevent loosening between the components; After the installation is completed, first open the control valve 17 on the light phase liquid inlet pipe 43, introduce distilled water between the uppermost vibration screen plate 8 and the upper flange 1 of the vibration tower to form a static pressure liquid seal, and adjust the flow rate of the light phase liquid inlet pipe 43 to 10L / h through the control valve 17; Then, the driving motor 91 is turned on, and the output shaft rotates to drive the sleeve 92 and the eccentric wheel 93 to rotate. When the eccentric wheel 93 rotates, the eccentric shaft 94 makes a circular motion along the center of the eccentric wheel 93, and the connecting rod 96 swings through the rolling bearing 95. The swing of the connecting rod 96 is transmitted to the first connecting sleeve 101, and then the motion is transmitted to the second connecting sleeve 102 through the universal joint 103, driving the vibration shaft 7 to vibrate, and then driving the vibration screen plate 8 fixed on the vibration shaft 7 to vibrate up and down in the extraction tower body 3, interacting with the heavy phase and light phase liquid flowing in the extraction tower body 3, and the vibration breaks the liquid boundary layer, reduces the mass transfer resistance, improves the mass transfer coefficient, accelerates the transfer of solutes between the two phases, and realizes efficient extraction; During the vibration process, if the vibration shaft 7 is laterally offset due to the impact of liquid flow or its own deformation, the universal joint 133 converts the lateral force into rolling resistance in the joint through the rolling friction characteristics of its joint rolling bearing, rather than directly acting on the vibration shaft 7, thereby eliminating the influence of the lateral tension on the stability of the shaft system and eliminating the lateral tension. At the same time, the universal joint 133 forms a dynamic centering effect during the vibration process. Under the action of the vibration axial force, its joint rolling bearing always tends to maintain the minimum resistance movement path, that is, automatically corrects the slight deflection of the vibration shaft 7, so that it maintains coaxiality with the tower body axis, thereby minimizing the deflection of the vibration shaft 7 due to uneven force and movement deviation, thereby minimizing the stability of the vibration extraction process and the extraction effect; At the same time, during the vibration of the vibration shaft 7, the bottom sleeve 11 and the linear bearing 13 provide support and guidance for the bottom and top ends of the vibration shaft 7 respectively. When the vibration shaft 7 slides up and down in the linear bearing 13 and the bottom sleeve 11, the liquid in the bottom sleeve 11 can be discharged from the bottom sleeve 11 through the liquid guide groove 12, thereby eliminating the axial suction force caused by the excessive closeness between the vibration shaft 7 and the bottom sleeve 11 as much as possible, making it easier for the bottom of the vibration shaft 7 to enter and exit the bottom sleeve 11, thereby reducing the load of the drive motor 91; Then open the control valve 17 on the heavy phase liquid inlet pipe 41 and adjust the flow rate of the heavy phase liquid inlet pipe 41 to 10L / h through the control valve 17, and then adjust the position of the two-phase liquid interface in the extraction tower body 3 through the liquid level regulating valve 19 to maintain the interface approximately between the uppermost vibration screen plate 8 and the flange 1 on the vibration tower. The height design of the liquid level regulating valve 19 can utilize the static pressure energy of the liquid to reduce the potential energy fluctuation when discharging the liquid and improve the flow stability. After the feed is stable for 10 minutes, discharge 25ml of light phase sample and 25ml of heavy phase sample through the light phase liquid outlet pipe 42 and the control valve 17 on the light phase liquid inlet pipe 43 for analysis; The vibration frequency is changed by adjusting the rotation speed of the output end of the driving motor 91, the above operation is repeated, and the analysis data of the outlet composition at the corresponding rotation speed is recorded; After use, close all control valves 17, liquid level regulating valve 46 and drive motor 91.
