Description

Technical Field

[0001] This invention relates to the field of extraction apparatus, and in particular to an extraction apparatus for the research and development of high-content salicylnitrile. Background Technology

[0002] Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation that separates mixtures by utilizing the different solubilities of components in a solvent. Specifically, it involves using the difference in solubility or partition coefficient of a substance in two immiscible solvents to transfer a solute from one solvent to the other. It is widely used in chemical, metallurgical, and food industries, and is commonly applied in the petroleum refining industry. Currently, research on salicylates requires extraction of high-content salicylates. Extraction is generally carried out in an extraction vessel, and to ensure extraction efficiency, the cleanliness of the extraction vessel is crucial.

[0003] A novel extraction device is disclosed in Chinese Utility Model Patent Application No. 201820077247.7. This device includes an extraction tank, a first switch installed in the middle of the outer wall of the left end of the extraction tank, a second switch installed below the first switch, electromagnets embedded in the inner cavities of both the left and right side walls of the extraction tank, a first opening at the upper right end of the extraction tank, a second opening at the middle of the lower end of the extraction tank, and second supports connected to both the left and right ends of the bottom of the extraction tank. This novel extraction device uses a motor and rollers to drive a sealing plate connected by a nylon rope to move up and down. The sealing plate has a sealing ring, a third opening, a spring, a movable plate, a sealing sleeve, and an iron plate. The electromagnets and the iron plate are firmly attracted, effectively separating the upper and lower solutions after extraction using the sealing plate. This prevents the upper solution from mixing in when the lower solution is extracted, thus improving the quality of the extracted solution.

[0004] In the aforementioned prior art, after the extraction and drainage are completed, a large amount of liquid remains on the inner wall of the extraction tank. Because the inner wall is covered with liquid, manual cleaning is not only time-consuming and laborious, but also results in incomplete cleaning. Poor cleaning will affect subsequent extraction work.

[0005] Therefore, it is necessary to propose an extraction device for the research and development of high-content salicylnitrile to solve the above problems. Summary of the Invention

[0006] The main objective of this invention is to provide an extraction device for the research and development of high-content salicylates, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0011] Preferably, each displacement block corresponds to two movable rods, the movable rods correspond to the connecting seat, and the guide wheel is movably connected to the inner side of the guide groove, so that the displacement of the movable rods can drive the connecting plate to change the tilt angle around the movable connection point with the connecting seat.

[0012] Preferably, the push block and the displacement block correspond one-to-one, and the side of the push block facing the displacement block and the side of the displacement block facing the push block are adapted inclined surfaces, so that when the rotating disk drives the push block to rotate, it will contact the displacement block and push the displacement block to move.

The rotating mechanism includes a bracket provided on the top of the first protective cover. Arc-shaped plates are symmetrically provided at opposite ends of the top of the cover plate. An arc-shaped through groove is provided at the upper end of the first protective cover corresponding to the arc-shaped plate. The upper end of the arc-shaped plate extends to the top of the first protective cover through the arc-shaped through groove. A top plate is provided on the top of the two arc-shaped plates. A first motor for driving the top plate to rotate is provided on the upper end of the bracket.

[0016] Preferably, the arc-shaped plate is smaller than the arc-shaped through groove, and the arc-shaped plate is movably connected to the arc-shaped through groove. A support cylinder is provided on the bottom periphery of the top plate, and ball bearings are evenly and movably arranged on the bottom of the support cylinder. The bottom of the ball bearings protrudes from the bottom of the support cylinder and rolls in cooperation with the top of the bracket. A second protective cover is provided above the first protective cover to cover the top plate and the bracket.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example

[0033] like Figures 1-8As shown in this embodiment, an extraction device for the research and development of high-content salicylates includes an extraction vessel 1, an inlet 2 located on one side of the upper end of the extraction vessel 1, and an outlet 3 located at the bottom end of the extraction vessel 1. A first protective cover 4 is provided at the top of the extraction vessel 1, and a spraying mechanism is provided inside the first protective cover 4. The spraying mechanism includes an annular groove 13 located inside the first protective cover 4 and open at the top. A partition 23 is provided inside the annular groove 13, a rotating disk 17 is provided at the upper end of the partition 23, and a drive mechanism for rotating the rotating disk 17 is provided at the bottom of the partition 23. The second motor 24 rotates. Push blocks 18 are evenly arranged on the outer side of the rotating disk 17. Connecting seats 21 are evenly arranged on the outer side of the lower end of the annular groove 13. A connecting plate 22 is movably connected to the connecting seat 21. The connecting plate 22 and the connecting seat 21 are movably connected by a pin, rivet, or bolt. A nozzle 16 is arranged on the side of the connecting plate 22 away from the annular groove 13. A water pipe 10 is inserted through the middle of the upper end of the first protective cover 4. The lower end of the water pipe 10 extends downward. A branch pipe 15 is arranged on the upper end of the nozzle 16. The end of the branch pipe 15 away from the nozzle 16 is connected to... The lower end of the water pipe 10 is connected, and the branch pipe 15 is a flexible hose. The side wall of the connecting plate 22 is provided with a guide groove 25. The upper outer side of the annular groove 13 is evenly connected with movable rods 20. One end of the movable rod 20 extends to the inner side of the annular groove 13, and the outer end of the movable rod 20 is provided with a guide wheel 27, and the inner end is provided with a displacement block 19. Each displacement block 19 corresponds to two movable rods 20. The outer end of the movable rod 20 corresponds to the connecting seat 21. The push block 18 corresponds one-to-one with the displacement block 19. The side of the push block 18 facing the displacement block 19 and the side of the displacement block 19 facing the displacement block 19 are respectively... The push block 18 has a fitted inclined surface on one side, so that when the rotating disk 17 drives the push block 18 to rotate, it will contact the displacement block 19 and push the displacement block 19 to move. The guide wheel 27 is movably connected to the inner side of the guide groove 25, so that the displacement of the movable rod 20 can drive the connecting plate 22 to change the tilt angle around the movable connection with the connecting seat 21. The displacement block 19 is provided with a first spring 26 on the side close to the movable rod 20. The end of the first spring 26 away from the displacement block 19 is fixed to the inner wall of the annular groove 13. When the movable rod 20 moves outward, the first spring 26 contracts.

[0034] Furthermore, a cover plate 14 is provided on the top of the annular groove 13, and a rotating mechanism is provided on the upper end of the first protective cover 4. The rotating mechanism includes a bracket 6 provided on the top of the first protective cover 4. Arc-shaped plates 9 are symmetrically provided at opposite ends of the top of the cover plate 14. An arc-shaped through groove 11 is provided at the upper end of the first protective cover 4 corresponding to the arc-shaped plates 9. The upper end of the arc-shaped plates 9 extends to the top of the first protective cover 4 through the arc-shaped through groove 11. A top plate 7 is provided on the top of the two arc-shaped plates 9. The arc-shaped plates 9 are smaller than the arc-shaped through groove 11, and the arc-shaped plates 9 are movably connected to the arc-shaped through groove 11. A first motor 12 for driving the top plate 7 to rotate is provided on the upper end of the bracket 6.

[0035] Furthermore, a support cylinder 8 is provided on the bottom periphery of the top plate 7. Ball bearings are evenly and movably arranged on the bottom of the support cylinder 8. The bottom of the ball bearings protrudes from the bottom of the support cylinder 8 and rolls in cooperation with the top of the bracket 6. A second protective cover 5 is provided above the first protective cover 4 to cover the top plate 7 and the bracket 6. One end of the water pipe 10 extends to the outside of the second protective cover 5 and is provided with a connector.

[0036] Furthermore, it also includes a rapid discharge mechanism, which includes transmission housings 28 disposed on both sides of the discharge port 3. A rack 32 is movably disposed at one end of the inner cavity of the transmission housing 28. A second spring 33 is disposed between the top of the rack 32 and the inner top of the transmission housing 28. A connecting post 34 extending to the bottom of the transmission housing 28 is disposed at the bottom of the rack 32. A support plate 29 is disposed at the bottom of the two connecting posts 34. A rotating shaft 31 is rotatably connected to the discharge port 3. The two ends of the rotating shaft 31 extend to the inner sides of the two transmission housings 28 respectively. Blades 35 are evenly disposed on the side wall of the part of the rotating shaft 31 located inside the discharge port 3. A gear 30 is disposed on one end of the rotating shaft 31 located in the transmission housing 28. The gear 30 meshes with the rack 32. The connecting post 34 is movably connected to the transmission housing 28. Thus, when the support plate 29 is pressed, the connecting post 34 drives the rack 32 to move downward and stretch the second spring 33. Then, the gear 30 rotates and drives the blades 35 to rotate through the rotating shaft 31.

[0037] Working principle: After extraction, the receiving device is placed on the support plate 29. Then, the valve on the outlet 3 can be opened to drain the liquid. As the liquid drains, the pressure on the support plate 29 increases. This causes the rack 32 to move downwards via the connecting column 34, stretching the second spring 33. This, in turn, causes the gear 30 and the rotating shaft 31 to rotate as a whole. Consequently, the blade 35 is driven to flip inside the outlet 3. The blade 35 increases the liquid's falling speed and prevents blockage. After removing the receiving device, the second spring 33 returns to its original position, allowing the support plate 29 to rise and reset. When cleaning the inner wall of the extraction vessel 1, a clean water source is connected to the outer end of the water pipe 10. The second motor 24 is started, causing the rotating disk 17 to rotate continuously. The first motor 12 is started, rotating in both directions. The rotating plate 7 rotates back and forth, and the rotating plate 7 drives the annular groove 13 to rotate back and forth through the arc plate 9. During this time, the rotating disk 17 drives the push block 18 to continuously contact and separate from the displacement block 19. When they contact each other, the displacement block 19 drives the movable rod 20 to move outward. The movable rod 20 can drive the overall tilt angle of the connecting plate 22 and the nozzle 16 to change through the action of the guide wheel 27 and the guide groove 25. When the push block 18 separates from the displacement block 19, the first spring 26 returns to its original position, the movable rod 20 retracts, and then the overall tilt angle of the connecting plate 22 and the nozzle 16 changes in the opposite direction. Thus, the nozzle 16 can achieve a comprehensive rinsing and cleaning of the upper and lower ends of the inner wall of the extraction vessel 1, which improves efficiency and increases convenience. The first protective cover 4 and the second protective cover 5 play a protective role.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
