A distillation device for removing residual solvent from artemisia annua oil

Abstract

This invention discloses a distillation apparatus for removing residual solvent from artemisia annua oil, comprising: an outer frame unit, the outer frame unit including a support frame and a rotation drive source installed on the side of the support frame; and a distillation processing unit, the distillation processing unit being rotatably disposed inside the support frame. The apparatus raises the receiving cavity formed by two closing plates, pressing a filter block into the receiving cavity. The artemisia annua solvent mixture flows through the filter holes inside the filter block to the surface of the heating ring plate, leaving the artemisia annua powder inside the receiving cavity. The artemisia annua solvent mixture then descends along the surface of the heating ring plate under its own gravity, and with the rotation of the cylinder, the mixture spirals down the surface of the heating ring plate, forming a moving film on its surface. This allows the mixture to be rotated and spread out, and fully heated by the second heating cavity at the bottom of the heating ring plate, thereby evaporating and discharging the solvent in the mixture whose boiling point is lower than that of artemisia annua oil.

[0001] The invention relates to the technical field of artemisia annua oil processing, in particular to a distillation device for removing residual solvent of artemisia annua oil. Background Art

[0002] In the process of extracting artemisia annua oil, organic solvents (such as ethanol, ethyl acetate, etc.) are usually used to dissolve and separate the active ingredients. After the extraction is completed, a certain amount of solvents may remain in the artemisia annua oil. Removing these solvents by distillation can significantly improve the purity of artemisia annua oil, making it more suitable for further application or processing.

[0003] Chinese patent CN115746952A discloses a device for removing residual solvents from artemisia annua oil, comprising a box, a separation mechanism is provided in the inner cavity of the box, a fixed plate is fixedly installed on the inner wall of the box, the separation mechanism is arranged on the top of the fixed plate, a centrifugal distillation mechanism is provided in the inner cavity of the box, and a collecting mechanism is provided on one side of the box. The device for removing residual solvents from artemisia annua oil can completely remove the residual solvent in artemisia annua oil by setting a separation mechanism, a centrifugal distillation mechanism and a collecting mechanism. Compared with the removal method of the prior art, the efficiency is higher, and the work intensity of the staff can be reduced. The operator does not need to repeat the same separation method for many times to separate the solvent in the artemisia annua oil, thereby ensuring that the solvent is separated in the process of separation, reducing the separation cost, and improving the separation efficiency while ensuring the effect of the solvent removal.

[0004] The above patents and prior art have the following problems:

[0005] After the existing artemisia annua oil extraction is completed, the mixed liquid after the extraction needs to be transferred to the distillation equipment, and the extract needs to be filtered during the process to reduce the impact of the residual artemisia annua powder in the subsequent distillation process. The above process has many steps, which can easily cause accidental dirt from the intermediate environment to enter the mixed liquid, affecting the distillation effect. In addition, the process time is often long, the degree of automation is low, and overall automation cannot be achieved. Summary of the invention

[0025] Beneficial effects of the present invention:

[0026] (i) opening the sealed door on the side of the cylinder, adding the solvent and the crushed Artemisia annua powder into the bottom circular concave plate, and then starting the heating element in the heating chamber to heat the solvent and the Artemisia annua powder on the top of the bottom circular concave plate, and then starting the rotary drive source to drive the lower sleeve and the cylinder on the top of the lower sleeve to rotate through the belt, so that the cylinder as a whole rotates, and the solvent and the Artemisia annua powder on the top of the bottom circular concave plate inside the cylinder are rotated and mixed.

[0027] (ii) During the rotation of the cylinder, the column will be driven to move inside the guide rail through the inclined rail, and the guide rail is composed of an inner push section and an outer push section. When the column moves from the inner push section to the outer push section, the column will drive the push plate to move outward along the bottom circular concave plate, and when the column moves from the outer push section to the inner push section, the column will drive the push plate to move inward along the bottom circular concave plate. Therefore, through the rotation of the cylinder and the reciprocating push of the push plate, the mixed liquid is subjected to reciprocating thrust during rotation, so that the liquid is sheared, the disturbance degree of the liquid is increased, the artemisia annua powder and the solvent are fully dissolved, and the efficiency of extracting artemisia annua oil is improved.

[0028] (III) The shape design of the bottom circular concave plate makes the middle bottom outer side of the bottom circular concave plate higher, so that the Artemisia annua powder and the solvent can be fully immersed and contacted, and the reciprocating push plate can reduce the Artemisia annua powder on the bottom surface of the bottom circular concave plate from being heated and coked, thereby causing the bottom to burn. The shape design of the bottom circular concave plate can reduce the Artemisia annua powder inside the bottom circular concave plate from being thrown out of the range of the bottom circular concave plate due to the rotation of the cylinder.

[0029] (iv) starting the driving source, so that the driving source drives the sealing round block and the lifting sealing plate at the bottom of the pulling rod to be lifted upward through the movable rod and the cross rod, so that the accommodating chamber formed by the closing plate 1 and the closing plate 2 is lifted upward, so that the accommodating chamber is driven by the pulling rod to be lifted upward and close to the filter press block, and finally the accommodating chamber is inserted into the interior of the confining groove, and the filter press block is pressed into the interior of the accommodating chamber, so that the Artemisia annua solvent mixture flows into the surface of the heating ring plate through the filter holes inside the filter press block, so that the Artemisia annua powder is retained in the accommodating chamber, and then the Artemisia annua solvent mixture flows downward along the surface of the heating ring plate under its own gravity, and with the rotation of the cylinder, the mixture spirally descends on the surface of the heating ring plate to form a moving film on its surface, so that the mixture can be rotated and spread and fully heated by the heating chamber 2 at the bottom of the heating ring plate, so that the solvent in the mixture with a boiling point lower than that of the Artemisia annua oil is evaporated and discharged, thereby removing the solvent in the Artemisia annua oil.

[0030] (V) The heating chamber three is heated, and the bottom of the umbrella plate is also heated, so that the heating of the liquid inside the bottom circular concave plate can be reduced, and the condensation effect caused by the internal liquid rising to the bottom of the hot umbrella plate can be reduced. The lifting of the movable rod will cause the movable rod to be pulled out from the empty column groove and the middle part of the hot umbrella plate, so that the empty column groove and the middle part of the hot umbrella plate are opened, and then the steam rising from the top of the bottom circular concave plate is discharged through the exhaust port and the through hole in the middle of the hot umbrella plate, and the rising steam is discharged through the exhaust pipe on the top of the hot umbrella plate, thereby preventing condensed water from dripping into the interior of the mixed liquid on the top of the bottom circular concave plate, thereby affecting the concentration of the bottom circular concave plate.

[0031] (six) when the contact between the containing chamber and the filter block is completed, the pulling rod is pushed downward to reset, so that the sealing round block and the lifting sealing plate at the bottom of the pulling rod move downward along the ring pulling plate, so that the lifting sealing plate finally contacts with the bottom connecting plate, and the lifting sealing plate pushes the bottom connecting plate to move downward, so that the bottom of the containing chamber is opened, and when the sealing round block and the lifting sealing plate enter the interior of the slag storage chamber through the pushing chamber and the slag discharge pipe, the outer sides of the closing plate 1 and the closing plate 2 will contact with the bottom support block, and under the obstruction of the bottom support block and the pulling of the middle connecting piece of the closing plate 1 and the closing plate 2 by the ring pulling plate, the connection between the closing plate 1 and the closing plate 2 is closed inward, so that the closing plate 1 and the closing plate 2 form a "V" shape, so that the Artemisia annua powder on the top surface of the containing chamber after being filtered by the filter block is closed inward along the inclined surface formed by the closing plate 1 and the closing plate 2, and enters the interior of the slag storage chamber through the middle circular opening inside the containing chamber along the shrinkage chamber and the slag discharge pipe, thereby completing the cleaning of the surface of the closing plate 1 and the closing plate 2.

[0032] (VII) In order to improve the degree of removal of the Artemisia annua powder on the surface of the containing cavity, the pushing plate can push the mixed liquid to flush the containing cavity, while the pushing plate will not move during the movement of the closing plate 1 and the closing plate 2 inside the pushing cavity. After the flushing is completed, the lifting sealing plate and the sealing round block are lifted again to contact with the connecting piece, so that the middle part of the closing plate 1 and the closing plate 2 is lifted, so that the containing cavity surrounded by the closing plate 1 and the closing plate 2 is pushed and expanded, so that the pushing plate can push the mixed liquid into the containing cavity, and the slag is discharged again by pressure filtration and distillation.

The closing plate 1 2061 is movably connected with the inside of the through groove 20621 through the protruding plate 20611. It should be noted that there is no connecting piece 2064 at the joint between the protruding plate 20611 and the through groove 20621. The gap at the bottom of the joint between the protruding plate 20611 and the through groove 20621 and the gap inside the connecting piece 2064 are both lifted by the sealing plate 20135 to cooperate with the rubber contact seal on its surface.

[0074] The rest of the structure is the same as that of the first embodiment.

[0075] Operation process:

[0076] The shape design of the bottom circular concave plate 202 makes the outer side of the middle bottom of the bottom circular concave plate 202 higher, so that the Artemisia annua powder and the solvent can be fully immersed and contacted, and the reciprocating push plate 205 can reduce the Artemisia annua powder on the bottom surface of the bottom circular concave plate 202 from being heated and coked, thereby causing the bottom to be burnt, and the shape design of the bottom circular concave plate 202 can reduce the range of the Artemisia annua powder inside the bottom circular concave plate 202 driven by the rotation of the cylinder 201 to be thrown out of the bottom circular concave plate 202;

[0077] After the solvent and the Artemisia annua powder on the top of the bottom circular concave plate 202 are fully dissolved, the push plate 205 pushes outward to drive the liquid mixed with the Artemisia annua powder to flow into the accommodating chamber 2063 inside the pushing chamber 2033. After the accommodating chamber 2063 receives the liquid mixed with the Artemisia annua powder, it should be noted that before the accommodating chamber 2063 receives the liquid, the sealing round block 20134 has been inserted into the middle circular opening 20631 for sealing, and the lifting sealing plate 20135 will lift the connection between the closing plate 1 2061 and the closing plate 2 2062 to support and seal the bottom;

[0078] The driving source 2013 is started again, so that the driving source 2013 drives the sealing round block 20134 and the lifting sealing plate 20135 at the bottom of the pulling rod 20133 to be lifted upward through the movable rod 20131 and the cross rod 20132, so that the accommodating chamber 2063 formed by the closing plate 1 2061 and the closing plate 2062 is lifted upward, so that the accommodating chamber 2063 is driven by the pulling rod 20133 to be lifted upward and close to the filter block 20331, and finally the accommodating chamber 2063 is inserted into the interior of the surrounding groove 20332, and the filter block 20331 is pressed into the interior of the accommodating chamber 2063, so that the artemisia annua solvent mixture passes through the pressure filter. The filter holes inside the filter block 20331 flow into the surface of the heating ring plate 2031, so that the artemisia annua powder is retained inside the containing cavity 2063, and then the artemisia annua solvent mixed liquid flows downward along the surface of the heating ring plate 2031 due to its own gravity, and with the rotation of the cylinder 201, the mixed liquid spirally descends on the surface of the heating ring plate 2031 to form a moving film on its surface, so that the mixed liquid can be spread by rotation and fully heated by the heating cavity 2032 at the bottom of the heating ring plate 2031, so that the solvent in the mixed liquid with a boiling point lower than that of the artemisia annua oil is evaporated and discharged, thereby removing the solvent inside the artemisia annua oil;

[0079] The mixed liquid passing through the heating ring plate 2031 will flow into the surface of the hot umbrella plate 204, and under the guidance of the inclined surface of the hot umbrella plate 204 and the heating of the heating chamber 3 2041 at the bottom of the hot umbrella plate 204, the solvent inside the mixed liquid is heated and boiled and discharged, thereby further removing the solvent inside the mixed liquid, so that the processed artemisia annua oil flows into the space between the vertical ring plate 2043 and the inner cylinder sleeve 203 for storage, and is conveniently discharged by the liquid outlet pipe 2035;

[0080] During the period when the filter press block 20331 is in contact with the accommodating chamber 2063, the cylinder 201 rotates to cause the liquid inside the filter hole of the filter press block 20331 to be thrown out, and the liquid pauses for a preset time after the preset throwing-out time, so that the thrown-out liquid flows through the filter press block 20331 to the surface of the heating ring plate 2031.

[0081] The heating chamber three 2041 is heated, and the bottom of the heat parachute plate 204 is also heated, so that the heating of the liquid inside the bottom circular concave plate 202 can be reduced, and the condensation effect caused by the internal liquid rising to the bottom of the heat parachute plate 204 can be reduced, and the lifting of the movable rod 20131 will cause the movable rod 20131 to be withdrawn from the empty column groove 20171 and the middle part of the heat parachute plate 204, so that the empty column groove 20171 and the middle part of the heat parachute plate 204 are opened, and then the steam rising from the top of the bottom circular concave plate 202 is discharged through the exhaust port 20172 and the through hole in the middle of the heat parachute plate 204, and the rising steam is discharged through the exhaust pipe 2014 at the top of the heat parachute plate 204, so as to prevent condensed water from dripping into the interior of the mixed liquid at the top of the bottom circular concave plate 202, thereby affecting the concentration of the bottom circular concave plate 202;

[0082] When the contact between the accommodating chamber 2063 and the filter press block 20331 is completed, the pulling rod 20133 is pushed downward to reset, so that the sealing round block 20134 and the lifting sealing plate 20135 at the bottom of the pulling rod 20133 move downward along the ring pulling plate 2065, so that the lifting sealing plate 20135 finally contacts with the bottom connecting plate 20651, and the lifting sealing plate 20135 pushes the bottom connecting plate 20651 to move downward, so that the bottom of the accommodating chamber 2063 is opened, and when the sealing round block 20134 and the lifting sealing plate 20135 enter the interior of the slag storage chamber 2016 through the pushing chamber 2033 and the slag discharge pipe 2015, the outer sides of the closing plate 1 2061 and the closing plate 2 2062 will contact with the bottom support block 20333, and at the bottom support block Under the obstruction of 20333 and the pulling of the middle connecting piece 2064 of the closing plate 1 2061 and the closing plate 2 2062 by the ring pull plate 2065, the connection between the closing plate 1 2061 and the closing plate 2 2062 is closed inwardly, so that the closing plate 1 2061 and the closing plate 2 2062 are in a "V" shape, so that the Artemisia annua powder after being filtered by the filter block 20331 on the top surface of the accommodating cavity 2063 passes through the middle circular opening 20631 inside the accommodating cavity 2063 along the inward contraction cavity 20334 and the slag discharge pipe 2015 into the interior of the slag storage cavity 2016, thereby completing the cleaning of the surface of the closing plate 1 2061 and the closing plate 2 2062;

[0083] Of course, in order to improve the degree of removal of Artemisia annua powder on the surface of the accommodating chamber 2063, the pushing plate 205 can push the mixed liquid to flush the accommodating chamber 2063. During the movement of the closing plate 1 2061 and the closing plate 2062 inside the pushing chamber 2033, the pushing plate 205 will not move. After the flushing is completed, the lifting sealing plate 20135 and the sealing round block 20134 are lifted again to contact the connecting piece 2064, so that the middle part of the closing plate 1 2061 and the closing plate 2062 is lifted, so that the accommodating chamber 2063 surrounded by the closing plate 1 2061 and the closing plate 2062 is pushed to expand, so that the pushing plate 205 can push the mixed liquid into the accommodating chamber 2063 to perform pressure filtration and distillation to discharge slag again.

[0084] It should be noted that before the distillation process is carried out, the closing plate 1 2061 and the closing plate 2062 are lifted to block between the heating chamber 1 2021 and the pushing chamber 2033 to prevent excessive Artemisia annua powder from flowing into the pushing chamber 2033.
