Description

Technical Field

[0001] This utility model relates to the field of vibration extraction technology, specifically a vibration extraction tower. Background Technology

[0002] Liquid-liquid extraction, as an important separation technology, is widely used in many fields such as chemical engineering, food processing, pharmaceuticals, and environmental protection. The extraction column is one of the key pieces of equipment used in extraction; its principle is based on the difference in solubility of a solute in two immiscible solvents to achieve the separation and purification of the solute.

[0003] However, most existing vibratory extraction towers can only drive a vibrating screen to vibrate simply to promote the mixing and mass transfer of the two-phase liquids. This single motion mode is still not sufficient to break up droplets, resulting in a relatively low extraction efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies that only drive vibrating screens to promote mixing and mass transfer of two-phase liquids, which is insufficient for droplet breakage and results in relatively low mass transfer efficiency, this invention provides a vibrating extraction tower.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

A bidirectional drive assembly is provided at the top end of the connecting rod for driving the vibrating shaft to rotate while vibrating. Vertically uniformly arranged vibrating screen plates are fixedly connected to the outer wall of the vibrating shaft.

[0007] As a preferred technical solution of this utility model, a lower opening is provided at the center of the lower surface of the extraction tower body, a bottom bushing is rotatably connected in the lower opening, a limit groove is provided on the upper surface of the bottom bushing, and a limit block that matches the limit groove is fixedly connected to the bottom end of the vibration shaft.

[0008] As a preferred embodiment of this utility model, the bidirectional drive assembly includes a drive motor fixedly connected to one side of the outer wall of the L-shaped support. The output end of the drive motor is fixedly connected to an upper rotating shaft. A turntable is fixedly connected to the end of the upper rotating shaft away from the drive motor. An eccentric circular block is rotatably connected to the side of the outer wall of the turntable away from the upper rotating shaft. A bushing is rotatably connected to the outer wall of the eccentric circular block. An upper connecting rod is fixedly connected to one side of the outer wall of the bushing. A universal joint is fixedly connected to the bottom end of the upper connecting rod. The bottom end of the universal joint is fixedly connected to a connecting rod.

[0009] As a preferred embodiment of this utility model, a lower connecting seat is fixedly connected to one side of the upper surface of the L-shaped support, and a lower rotating shaft is rotatably connected inside the lower connecting seat. A first gear is fixedly connected to one end of the lower rotating shaft near the bottom bushing, and a second gear meshing with the first gear is fixedly connected to the bottom end of the bottom bushing. A first transmission sleeve is fixedly connected to one side of the outer wall of the upper rotating shaft, and a second transmission sleeve is fixedly connected to one side of the outer wall of the lower rotating shaft. A transmission belt for driving the second transmission sleeve to rotate following the first transmission sleeve is provided on the first and second transmission sleeves.

[0010] As a preferred embodiment of this utility model, the outer wall of the vibration shaft is fixedly connected to a spiral guide plate between two adjacent vibrating screen plates.

[0011] As a preferred embodiment of this utility model, the inlet and outlet liquid assembly includes a light phase drain pipe disposed on one side of the upper surface of the extraction tower body and a heavy phase drain pipe disposed on the lower surface of the extraction tower body away from the light phase drain pipe. A heavy phase inlet pipe is fixedly connected to the top end of the outer wall of the extraction tower body away from the light phase drain pipe, and a light phase inlet pipe is fixedly connected to the bottom end of the outer wall of the extraction tower body away from the heavy phase drain pipe. The light phase drain pipe, the heavy phase drain pipe, the heavy phase inlet pipe, and the light phase inlet pipe are all connected to the extraction tower body.

[0012] As a preferred embodiment of this utility model, control valves are provided on the outer walls of the light phase drain pipe, the heavy phase drain pipe, the heavy phase inlet pipe, and the light phase inlet pipe.

[0014] In summary, this application has the following beneficial effects:

[0015] 1. This application utilizes the combination of an L-shaped support, a support rod, an extraction tower body, inlet and outlet liquid components, an upper opening, a vertical bearing, a connecting rod, a vibration shaft, a bidirectional drive assembly, and a vibrating screen plate. During use, the bidirectional drive assembly can simultaneously drive the vibrating screen plate to rotate and vibrate. This composite motion mode can perform high-frequency shearing on the light and heavy phase liquids in the tower, breaking the liquid into fine droplets, maximizing the contact area between the two phase liquids, and thus effectively improving the extraction efficiency of the device.

[0016] 2. This application utilizes the cooperation between the spiral guide vanes on the outer wall of the vibrating shaft and the vibrating screen plate. Based on the shearing and crushing of the liquid by the vibrating screen plate, the spiral guide vanes guide the liquid to form a spiral flow state, prolonging the residence time of the liquid in the tower, reducing axial backmixing, making the liquid more uniformly mixed, and significantly improving the sufficiency and efficiency of extraction.

[0017] 3. This application uses the pressure relief hole on the upper surface of the bottom bushing to cooperate with the limiting groove, so that the internal space of the limiting groove is connected with the internal space of the extraction tower body, and the pressure in the limiting groove is balanced in time. This prevents the pressure difference between the inside and outside of the limiting groove from affecting the normal movement of the vibration shaft due to the tight fit between the limiting groove and the limiting block, thus ensuring the stability and reliability of the equipment operation.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] Example: Please refer to Figure 1 The present invention provides a vibrating extraction tower, including an L-shaped support 1, a rectangularly distributed support rod 2 fixedly connected to one side of the upper surface of the L-shaped support 1, an extraction tower body 3 fixedly connected to the top of the support rod 2, and an inlet / outlet liquid assembly 4 provided on the outer side wall of the extraction tower body 3.

[0027] The inlet / outlet assembly 4 includes a light phase drain pipe 41 disposed on one side of the upper surface of the extraction tower body 3 and a heavy phase drain pipe 42 disposed on the lower surface of the extraction tower body 3 away from the light phase drain pipe 41. A heavy phase inlet pipe 43 is fixedly connected to the top end of the outer wall of the extraction tower body 3 away from the light phase drain pipe 41, and a light phase inlet pipe 44 is fixedly connected to the bottom end of the outer wall of the extraction tower body 3 away from the heavy phase drain pipe 42. The light phase drain pipe 41 and the heavy phase drain pipe 42 are also connected to the heavy phase drain pipe 43. 2. Both the heavy phase inlet pipe 43 and the light phase inlet pipe 44 are connected to the extraction tower body 3. The outer walls of the light phase outlet pipe 41, heavy phase outlet pipe 42, heavy phase inlet pipe 43 and light phase inlet pipe 44 are equipped with control valves 17. The operator can adjust the opening of the control valves 17 on the light phase outlet pipe 41, heavy phase outlet pipe 42, heavy phase inlet pipe 43 and light phase inlet pipe 44 to control the inlet and outlet flow rates and velocities of the light and heavy phase liquids.

[0028] Reference Figure 2 , Figure 3 and Figure 4An upper opening 5 is provided at the center of the upper surface of the extraction tower body 3. A vertical bearing 6 is provided inside the upper opening 5. A connecting rod 7 is slidably connected inside the vertical bearing 6. A vibration shaft 8 is rotatably connected to the bottom end of the connecting rod 7. A bidirectional drive assembly 9 is provided at the top end of the connecting rod 7 to drive the vibration shaft 8 to rotate while vibrating. A vertically uniformly arranged vibrating screen plate 10 is fixedly connected to the outer wall of the vibration shaft 8. A spiral guide plate 15 is fixedly connected between two adjacent vibrating screen plates 10 on the outer wall of the vibration shaft 8. A lower opening 11 is provided at the center of the lower surface of the extraction tower body 3. A bottom bushing 12 is rotatably connected inside the lower opening 11. A limit groove 13 is provided on the upper surface of the bottom bushing 12. A limit block 14 that matches the limit groove 13 is fixedly connected to the bottom end of the vibration shaft 8. Pressure relief holes 18 that communicate with the bottom end of the inner side wall of the limit groove 13 are provided on both sides of the upper surface of the bottom bushing 12.

[0029] Reference Figure 1 , Figure 2 and Figure 3 The bidirectional drive assembly 9 includes a drive motor 91 fixedly connected to one side of the outer wall of the L-shaped support 1. The output end of the drive motor 91 is fixedly connected to an upper rotating shaft 92. The end of the upper rotating shaft 92 away from the drive motor 91 is fixedly connected to a turntable 93. The outer wall of the turntable 93 away from the upper rotating shaft 92 is rotatably connected to an eccentric circular block 94 that is eccentrically set with the turntable 93. The outer wall of the eccentric circular block 94 is rotatably connected to a bushing 95. One side of the outer wall of the bushing 95 is fixedly connected to an upper connecting rod 96. The bottom end of the upper connecting rod 96 is fixedly connected to a universal joint 97. The bottom end of the universal joint 97 is fixedly connected to a connecting rod 7.

[0030] The drive motor 91 starts, which in turn drives the upper rotating shaft 92 and the turntable 93 to rotate. Since the eccentric block 94 and the turntable 93 are eccentrically set, when the turntable 93 rotates, the eccentric block 94 and the bushing 95 make circular motion. The vertical bearing 6 supports and guides the connecting rod 7. The bushing 95 drives the connecting rod 7 to make up-down reciprocating motion along the vertical bearing 6 through the upper connecting rod 96 and the universal joint 97, which in turn drives the vibrating shaft 8 to generate axial vibration.

[0031] When the vibrating shaft 8 vibrates axially, the limiting block 14 slides up and down along the limiting groove 13, thereby driving the vibrating screen plate 10 to vibrate up and down continuously. At the same time, the pressure relief hole 18 can ensure that the internal space of the limiting groove 13 is connected to the internal space of the extraction tower body 3, thereby ensuring the stability of the pressure environment in the limiting groove 13 as much as possible, and thus ensuring the stability of the vibration of the vibrating shaft 8 as much as possible.

[0032] Reference Figure 1 and Figure 2A lower connecting seat 98 is fixedly connected to one side of the upper surface of the L-shaped support 1. A lower rotating shaft 99 is rotatably connected inside the lower connecting seat 98. A first gear 910 is fixedly connected to one end of the lower rotating shaft 99 near the bottom bushing 12. A second gear 911 that meshes with the first gear 910 is fixedly connected to the bottom end of the bottom bushing 12. A first transmission sleeve 912 is fixedly connected to one side of the outer wall of the upper rotating shaft 92. A second transmission sleeve 913 is fixedly connected to one side of the outer wall of the lower rotating shaft 99. A transmission belt 914 for driving the second transmission sleeve 913 to rotate with the first transmission sleeve 912 is provided on the first transmission sleeve 912 and the second transmission sleeve 913.

[0033] While the drive motor 91 drives the upper rotating shaft 92 to rotate, the first transmission sleeve 912 rotates synchronously with the upper rotating shaft 92 and transmits power to the second transmission sleeve 913 on the outer wall of the lower rotating shaft 99 through the transmission belt 914. This drives the lower rotating shaft 99 and the first gear 910 to rotate. The first gear 910 drives the second gear 911 and the bottom bushing 12 to rotate. When the bottom bushing 12 rotates, the vibration shaft 8 is driven to rotate through the cooperation of the limiting groove 13 and the limiting block 14. This causes the vibration shaft 8 to drive the vibrating screen plate 10 to rotate and vibrate. During the vibration process, the vibrating screen plate 10 performs high-frequency shearing on the light and heavy phase liquids in the tower, breaking the liquid into fine droplets. This greatly increases the contact area between the two phase liquids and improves the mass transfer efficiency. At the same time, the rotation of the vibration shaft 8 drives the vibrating screen plate 10 to rotate, causing the liquid to diffuse towards the tower wall under the action of centrifugal force, further promoting the mixing of the two phase liquids.

[0034] The spiral guide vanes 15 between adjacent vibrating screen plates 10 rotate with the vibrating shaft 8, guiding the liquid to form a spiral upward or downward flow state within the column. This changes the liquid's flow path, prolongs the liquid's residence time within the column, and allows for more thorough contact and mass transfer between the two phases. Simultaneously, the spiral flow helps reduce axial backmixing, making the liquid flow within the column more uniform and improving the extraction efficiency.

[0035] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0036] The implementation principle of this utility model is as follows:

[0037] In use, open the control valves 17 of the heavy phase inlet pipe 43 and the light phase inlet pipe 44, and slowly introduce the heavy phase and light phase materials into the extraction tower body 3 respectively. Then start the drive motor 91 to drive the upper rotating shaft 92 and the turntable 93 to rotate. Since the eccentric block 94 and the turntable 93 are eccentrically set, when the turntable 93 rotates, the eccentric block 94 and the bushing 95 make circular motion. The vertical bearing 6 supports and guides the connecting rod 7. The bushing 95 drives the connecting rod 7 to move up and down along the vertical bearing 6 through the upper connecting rod 96 and the universal joint 97, thereby driving the vibrating shaft 8 to generate axial vibration.

[0038] While the drive motor 91 drives the upper rotating shaft 92 to rotate, the first transmission sleeve 912 rotates synchronously with the upper rotating shaft 92 and transmits power to the second transmission sleeve 913 on the outer wall of the lower rotating shaft 99 through the transmission belt 914. This drives the lower rotating shaft 99 and the first gear 910 to rotate. The first gear 910 drives the second gear 911 and the bottom bushing 12 to rotate. When the bottom bushing 12 rotates, the vibration shaft 8 is driven to rotate through the cooperation of the limiting groove 13 and the limiting block 14. This causes the vibration shaft 8 to drive the vibrating screen plate 10 to rotate and vibrate. During the vibration process, the vibrating screen plate 10 performs high-frequency shearing on the light and heavy phase liquids in the tower, breaking the liquid into fine droplets. This greatly increases the contact area between the two phase liquids and improves the mass transfer efficiency. At the same time, the rotation of the vibration shaft 8 drives the vibrating screen plate 10 to rotate, causing the liquid to diffuse towards the tower wall under the action of centrifugal force, further promoting the mixing of the two phase liquids.

[0039] The spiral guide vanes 15 between adjacent vibrating screen plates 10 rotate with the vibrating shaft 8, guiding the liquid to form a spiral upward or downward flow state within the column. This changes the liquid's flow path, prolongs the liquid's residence time within the column, and allows for more thorough contact and mass transfer between the two phases. Simultaneously, the spiral flow helps reduce axial backmixing, making the liquid flow within the column more uniform and improving the extraction efficiency.

[0040] After extraction is complete, turn off the drive motor 91, stop the rotation of the vibration shaft 8, open the control valves 17 of the light phase drain pipe 41 and the heavy phase drain pipe 42 to discharge the light phase and heavy phase products respectively. After the drainage is complete, close all control valves 17.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
