Description

Technical Field

[0001] The invention relates to the technical field of distillation and purification, in particular to a distillation device for eucalyptol. Background Art

[0002] Eucalyptus oil is a colorless to light yellow oily liquid with a camphor and refreshing herbal smell. The method for preparing eucalyptus oil is generally steam distillation. Eucalyptus oil is extracted from branches and leaves by steam distillation, and then the eucalyptus oil is further purified by vacuum distillation according to the different boiling points and inclusion vapor pressures of the components in eucalyptus oil.

[0003] During the purification of eucalyptus oil, a plate distillation tower is often used for distillation. The principle of the plate distillation tower is based on the difference in volatility of each component in the mixture, and the separation and purification of the substance are achieved through the close contact of the gas-liquid two phases on the tower plate. The plate distillation tower will condense due to materials during use. Factors such as deposition cause the holes of the tower plate to be blocked. If the holes of the tower plate cannot be cleaned in time, the distillation tower may explode or leak. In the prior art, multiple top plates are installed on the upper side of the tower plate, and the top plates will move up and down during the rotation of the upper side of the tower plate, so as to achieve the dredging of the holes of the tower plate, and scrapers are installed on both sides of the upper and lower sides of the tower plate. However, since there are multiple tower plates in the plate distillation tower, the impurities cleaned from the upper tower plate will fall on the lower tower plate. During the rotation of the scraper on the upper side of the tower plate, the impurities that cannot fall through the holes of the lower tower plate will always accumulate on the outside of the scraper on the upper side of the tower plate, which will cause impurities to remain on the tower plate.

The limiting ring 403 can prevent the exhaust pipe 401 from falling into the distillation tower 1, and the outer circle diameter of the limiting ring 403 is equal to the outer circle diameter of the sleeve seat 402.

[0024] The lower end surface of the limiting ring 403 is movably abutted against the upper end surface of the sleeve seat 402, and the outer side of the exhaust pipe 401 is movably sleeved with a threaded cover 404, and the threaded cover 404 is located on the upper side of the limiting ring 403. The connection between the threaded cover 404 and the sleeve seat 402 is a threaded connection. When the threaded cover 404 is screwed onto the sleeve seat 402, the exhaust pipe 401 can be fixed to the upper end of the distillation tower 1. A plurality of exhaust holes 405 equidistantly distributed in a circle are provided on the outer side of the exhaust pipe 401, and the exhaust holes 405 are located on the upper side of the threaded cover 404.

[0025] The upper end of the exhaust pipe 401 is fixedly connected to a top plate 406, a hydraulic rod 407 is fixedly installed in the center of the top plate 406, the lower end of the hydraulic rod 407 is fixedly connected to a connecting seat 409, a piston 408 is fixedly sleeved on the outer side of the connecting seat 409, and the piston 408 can move up and down inside the exhaust pipe 401, and the hydraulic rod 407 can drive the piston 408 to move up and down.

[0026] A connecting pipe 15 is fixedly installed on the upper end of the distillation tower 1, and a cover pipe 9 is installed on the upper end of the connecting pipe 15, and the cover pipe 9 and the connecting pipe 15 are located on the outside of the exhaust structure 4, and the outsides of the cover pipe 9 and the connecting pipe 15 are fixedly sleeved with flanges 12, and the cover pipe 9 and the connecting pipe 15 are fixedly connected by the flange 12 and bolts, and a conduit 10 interconnected with the cover pipe 9 is fixedly installed on the upper end, and a condenser 11 is installed at the end of the conduit 10 away from the cover pipe 9, and the cover pipe 9 is rotatably connected to the condenser 11 through a rotary joint, and a conduit 2 13 interconnected with the connecting pipe 15 is fixedly installed on the outside of the connecting pipe 15, and the end of the conduit 2 13 away from the connecting pipe 15 is fixedly connected to the distillation tower 1, and the conduit 2 13 can discharge the condensed water between the connecting pipe 15 and the sleeve seat 402 into the distillation tower 1, and a reflux pipe 14 is fixedly installed on the outside of the distillation tower 1 near its upper end.

[0027] Working principle: the eucalyptus oil stock solution is located inside the distillation tower 1, and the distillation tower 1 heats the stock solution through high-temperature steam. During the heating process, the temperature inside the distillation tower 1 gradually increases. At this time, the piston 408 blocks the exhaust pipe 401 of the distillation tower 1, and the pressure inside the distillation tower 1 is increased, so that the fraction evaporates under high pressure, which can further improve the separation efficiency. When the temperature inside the distillation tower 1 reaches a certain value, the hydraulic rod 407 will drive the piston 408 to move up until the piston 408 moves up to the upper side of the exhaust hole 405. At this time, the gas inside the distillation tower 1 is discharged through the exhaust hole 405, and the distillation tower 1 is depressurized. After the distillation tower 1 is depressurized, the hydraulic rod 407 will drive the piston 408 to move down again, which can achieve indirect blocking of the exhaust pipe 401; The steam in the distillation tower 1 is discharged into the conduit 10 through the exhaust hole 405, and after being condensed by the condenser 11, part of the condensate flows back into the distillation tower 1 through the reflux pipe 14. The refluxed condensate flows inside the distillation tower 1 through multiple trays 2. The steam inside the distillation tower 1 passes through the tray 2 through multiple circular through holes during the rising process. During this period, the steam will contact with the condensate flowing on the tray 2. After multiple partial vaporizations and multiple partial condensations, the purpose of completely separating the light and heavy components is achieved. When the hydraulic rod 407 and the piston 408 need to be inspected or replaced, the personnel first remove the cover pipe 9, then rotate the threaded cover 404, rotate the exhaust pipe 401 to make the piston 408 separate from the long connecting rod 507, and then the hydraulic rod 407 and the piston 408 can be disassembled. Example 2: Please refer to Figure 4 , Figure 5 The present embodiment further explains Example 1, the anti-blocking structure 6 includes a grid plate 601 installed on the lower side of the tower plate 2, and the grid plate 601 is fixedly sleeved on the outer side of the long connecting rod 507, and a plurality of vertical rods 602 are fixedly embedded on the upper end of the grid plate 601, and the number of the vertical rods 602 is equal to the number of circular through holes opened on the tower plate 2, and the plurality of vertical rods 602 are located on the lower side of the plurality of circular through holes, and a wire brush 603 is fixedly connected to the upper end of the vertical rod 602, and the wire brush 603 can pass through the tower plate 2 through the circular through hole, and the wire brush 603 is in an umbrella shape, and the umbrella-shaped wire brush 603 can rub the side wall of the circular through hole when it moves downward inside the circular through hole.

[0028] In this embodiment: in the process of the long connecting rod 507 moving up and down with the piston 408, the grid plate 601 will move with the long connecting rod 507. In the process of the grid plate 601 driving multiple wire brushes 603 to move up and down, the wire brush 603 passes through the circular through hole on the tower plate 2, and then the wire brush 603 moves down inside the circular through hole. Since the wire brush 603 is umbrella-shaped, after the umbrella-shaped wire brush 603 moves down inside the circular through hole, the wire brush 603 will be stretched open by the tower plate 2, so that the wire brush 603 contacts and rubs against the side wall of the circular through hole during the downward movement, which can effectively prevent impurities from being deposited in the circular through hole on the tower plate 2, and prevent the circular through hole of the tower plate 2 from being blocked, and there is no need to dredge the circular through hole of the tower plate 2 in the later stage. Example 3: Please refer to Figure 6, this embodiment further explains Example 1, the stirring structure 5 includes a cylindrical rod 501 installed at the center of the lower part of the distillation tower 1, and a plurality of stirring rods 502 equidistantly distributed in a circle are fixedly installed on the outer side of the cylindrical rod 501, the stirring rods 502 are in the shape of an arc, and both ends of the stirring rods 502 are fixedly connected to the cylindrical rod 501, a supporting seat 503 is installed at the lower end of the cylindrical rod 501, and the cylindrical rod 501 is rotatably connected to the supporting seat 503 through a bearing, and the bearing can reduce the friction between the cylindrical rod 501 and the supporting seat 503, and a plurality of support rods 504 equidistantly distributed in a circle are fixedly installed on the outer side of the supporting seat 503, and the end of the support rod 504 away from the supporting seat 503 is fixedly connected to the distillation tower 1.

[0029] A cylindrical groove 505 is provided at the center of the upper end of the cylindrical rod 501, and a threaded groove 506 is provided on the side wall of the cylindrical groove 505. A long connecting rod 507 is movably embedded in the upper end of the cylindrical rod 501, and the long connecting rod 507 is plugged and connected to the cylindrical rod 501 through the cylindrical groove 505. The long connecting rod 507 passes through multiple tower plates 2 and can move up and down inside the distillation tower 1. A pin ball 508 is fixedly embedded on the outer side of the long connecting rod 507, and the pin ball 508 is located inside the cylindrical rod 501. The pin ball 508 is in sliding contact with the cylindrical rod 501 through the threaded groove 506, and the pin ball 508 can drive the cylindrical rod 501 to rotate through the threaded groove 506. An external thread 509 is provided on the upper end of the long connecting rod 507.

[0030] The long connecting rod 507 is threadedly connected to the connecting seat 409 through an external thread 509. A limiting assembly 8 is installed on the outer side of the long connecting rod 507 near the exhaust structure 4. The limiting assembly 8 includes a plurality of convex ribs 801 fixedly embedded on the outer side of the long connecting rod 507, and the convex ribs 801 are equidistantly distributed around the circumference. A ring 802 is movably sleeved on the outer side of the convex ribs 801. The ring 802 is sleeved on the outer side of the plurality of convex ribs 801 to prevent the long connecting rod 507 from rotating. A plurality of support rods 803 equidistantly distributed around the circumference are fixedly embedded on the outer side of the ring 802, and the end of the support rod 803 away from the ring 802 is fixedly connected to the distillation tower 1.

[0031] In this embodiment: the pin ball 508 is located inside the threaded groove 506. When the long connecting rod 507 moves up and down, the long connecting rod 507 and the pin ball 508 cannot rotate due to the restriction of the long connecting rod 507 by the limit assembly 8. Therefore, when the pin ball 508 moves up and down, the pin ball 508 will drive the cylindrical rod 501 and the stirring rod 502 to rotate through the threaded groove 506. Multiple stirring rods 502 rotate inside the distillation tower 1, which is beneficial to stirring the liquid inside the distillation tower 1, can speed up the heat transfer efficiency in the liquid, is beneficial to uniform distribution of heat in the liquid, and accelerates the heating speed of the liquid.

[0032] In this embodiment: during the up and down movement of multiple wire brushes 603, steam will flow in the gaps between the wire brushes 603, thereby passing through the circular through holes on the tower plate 2 through the wire brushes 603 to contact the condensate. When the wire brush 603 moves downward from the inside of the circular through holes, some condensate will also be attached to the wire brush 603. Since the multiple blocks 703 can vibrate the metal shrapnel 701 and the multiple wire brushes 603 during the movement of the metal shrapnel 701, the condensate attached to the wire brush 603 can be vibrated and diffused, which effectively increases the contact area between the liquid phase and the gas phase, facilitates mass transfer, accelerates the mass transfer rate of the components, and makes the fractionation in the tower more uniform.
