Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine distillation and extraction technology, and in particular to a receiving mechanism and a steam extraction distillation apparatus for extracting effective components from traditional Chinese medicine. Background Technology

[0002] Distillation and extraction apparatuses are core equipment used in the extraction of traditional Chinese medicine, fragrance processing, and chemical production to separate liquid mixtures or extract effective plant components. Traditional distillation apparatuses typically consist of a distillation kettle, a heating jacket, a condenser, and a receiving tank. Their working principle is based on the difference in boiling points of the components in the mixture. By heating, the liquid is vaporized, and then condensed and recovered, thereby achieving separation and purification.

[0003] However, existing traditional distillation equipment has revealed the following obvious technical defects in actual production processes: 1. Traditional distillation kettles typically use a single top opening for one-time feeding or a simple side feeding method. This method causes the material to accumulate naturally inside the kettle, lacking an orderly distribution structure, resulting in uneven heating of the material and low extraction efficiency. 2. After distillation and extraction, the material in the vessel usually becomes wet residue. Traditional equipment has serious shortcomings in the unloading process. Most traditional equipment only has a small drain outlet and cannot automatically discharge the waste residue. Operators often need to open the vessel lid and manually dig and clean it with tools. This is not only extremely labor-intensive and inefficient, but also increases the safety risks of personnel coming into contact with high-temperature equipment and residual solvents. Summary of the Invention

[0004] One of the objectives of this invention is to provide a receiving mechanism that can achieve layered and uniform heating of medicinal materials through a medicinal material receiving component set inside the distillation tank, thereby solving the problems of disordered feeding and difficult unloading in traditional equipment.

[0005] The objective of this invention is achieved through the following technical solution: a receiving mechanism, comprising a distillation tank and a medicinal material receiving assembly; the medicinal material receiving assembly includes a bushing, a receiving plate, and a support rod; The inner wall of the distillation tank is equipped with spreading rakes. A bushing is screwed to the middle of the top of the distillation tank. A central fixed shaft is fixed to the middle of the lower inner end of the distillation tank. Lifting guide grooves are evenly distributed on the outer cylindrical surface of the central fixed shaft. A bearing sleeve is slidably fitted inside the middle of the bushing. Here, "slidably fitted" means that the middle of the bushing and the bearing sleeve can form a sliding and rotating fit. A cylinder flange is screwed to the middle of the bearing sleeve. A discharge cylinder is installed and fixed at the top of the cylinder flange. A key shaft is slidably inserted into the bottom of the bushing. The bottom end of the push rod of the discharge cylinder is screwed to the key shaft and cannot be disengaged. The bottom end of the key shaft is symmetrically fixed with a support rod fixing block and an outer fixed column, and the support rod fixing block and the outer fixed column form a hollow cylindrical structure. This hollow cylindrical structure can rotate with the central fixed shaft as a reference. Lifting guide wheels are evenly screwed onto the inner circular surface of the outer fixed column, and the lifting guide wheels of the same layer are rolled and connected in the lifting guide groove. Each set of support rod fixing blocks has support rods vertically slidably inserted into the grooves on both sides of the main body, and the top of the support rods is fixedly connected to the bottom of the bearing sleeve. The fan-shaped support plates are arranged in a relatively hinged structure and are evenly and laterally screwed to different height positions on the outer circular surface of the outer fixed column. The bottom of each set of support plates is screwed with a rotating connecting rod. Tie rods are arranged and screwed between the support rods on each side. Support rods are arranged and screwed in the support rod fixing block on each side. The top of the support rod, the bottom of the rotating connecting rod and the outer end of the tie rod are screwed together on the same side. The technical solution of this invention is used as follows: The feeding and spreading of Chinese medicinal materials: The side wall of the distillation tank is obliquely opened with a feeding port that is directly opposite to each layer of receiving plate, so that the raw materials of Chinese medicinal materials can be quantitatively added to the top surface of each layer of receiving plate in the unfolded state. Then, the rotation drive mechanism of the bushing is activated, causing the bushing to rotate around the center axis of the distillation tank. The bushing drives the key shaft to rotate synchronously through a sliding fit. The key shaft drives the rotation of the support rod fixing block and the outer fixed column that are fixed to it. At this time, the lifting guide wheel installed in the inner circular surface of the outer fixed column is embedded in the lifting guide groove opened in the middle fixed shaft. With the rotation, the lifting guide wheel is forced to move along the trajectory of the lifting guide groove, transforming the single rotational motion of the bushing into a compound motion of rotation and reciprocating lifting of the support rod fixing block and the outer fixed column. This causes the receiving plate to perform slight up and down shaking while rotating. This compound motion, combined with the raking action of the spreading rake on the inner wall of the distillation tank, causes the Chinese medicinal materials to continuously roll and shift on the top surface of the receiving plate, eventually achieving uniform flatness. This ensures good air permeability of the medicinal material layer and provides the best stacking state for subsequent extraction. After the medicinal materials are laid out, the distillation and extraction stage begins. Each layer of the receiving plate has micropores that allow only steam to pass through. High-temperature steam enters from the bottom of the distillation tank, passes through the layers of Chinese medicinal materials on each receiving plate, and carries volatile components to rise into the condensation system. During the extraction process, in order to achieve further uniform heating, the receiving plate continues to rotate slowly and move up and down slightly. After distillation and extraction, the Chinese medicinal materials are unloaded. After the extraction is completed, the medicinal materials become dregs and need to be discharged. At this time, the bushing stops rotating and stops at a fixed point. The lifting guide wheel on the inner circular surface of the outer fixed column stops at a specific position in the lifting guide groove (usually the lower stop or the locking position), so that the key shaft is relatively fixed. When the unloading cylinder is activated, the control push rod extends downwards and abuts against the top of the key shaft. Since the key shaft is already limited by the lifting guide wheel and lifting guide groove, it cannot move downwards. According to the principle of mechanical reaction force, the key shaft generates an upward reaction force on the unloading cylinder. This reaction force pushes the unloading cylinder to move upwards against the cylinder's own weight, thereby driving the cylinder flange, bearing sleeve, and support rod to move upwards synchronously. The support rod pulls the tie rod upwards. As the driving component, the tie rod pulls the support rod and rotating connecting rod through the same swivel joint, thereby causing the receiving plate to flip downwards and open around the hinge point on the outer circular surface of the outer fixed column.

[0006] The moist dregs fall off rapidly under the influence of gravity and are discharged through the normally closed outlet at the bottom of the distillation tank, completing the unloading process. After unloading, the push rod of the unloading cylinder retracts, all components reset, the receiving plate closes, and it is ready for the next batch of feeding.

[0007] The distillation tank also includes an outer tank, an inner tank, and a rubber plug. The inner and outer tanks are distributed inside and outside the tank, together forming the tank structure of the distillation tank. The side wall of the inner tank is connected with a feeding channel, which extends outward through the main body of the outer tank. The rubber plug is inserted into the feeding channel with an interference fit to achieve a seal during distillation; The spreading rakes are arranged and fixed to the inner wall of the inner tank; The outer side of the distillation vessel is also equipped with a support frame, and the outer wall of the outer vessel is snapped and fixed to the inner frame of the support frame to support the distillation vessel.

[0008] Another objective of this invention is to provide a steam extraction distillation apparatus for extracting effective components from traditional Chinese medicine, which further includes a tank insulation component, a condenser component, a refrigeration compressor pump, an oil-water separator, and a tank cover component. The tank insulation assembly includes a support and an insulation water heater. The insulation water heater is fixedly installed on the bottom of the outer wall of the outer tank through the support. The top outlet of the insulation water heater is connected to a circulating water pump. An inlet pipe is connected between the cavity wall of the outer tank and the outlet of the circulating water pump. A return pipe is connected between the bottom inlet of the insulation water heater and the top of the outer wall of the outer tank. The heat-insulating water heater is equipped with an electric heating wire and can be filled with sufficient water. The heated water in the heat-insulating water heater can be pumped by the circulating water pump to the cavity between the inner wall of the outer tank and the outer wall of the inner tank, and then flow back to the heat-insulating water heater to achieve the purpose of heat preservation of the inner tank. The condensing assembly includes a bracket and a condenser. The condenser is fixedly installed on the upper part of the outer wall of the outer tank by the bracket. The inlet of the condenser passes through the cavity wall of the outer tank and connects to the inner top of the inner tank. The outlet of the condenser is connected to an oil-water separator, which is fixedly installed on the bracket. The cold air outlet of the refrigeration compressor pump is connected to the condenser assembly, and the hot air outlet is connected to the cavity wall of the insulated water heater. During the distillation and extraction process, the high-temperature volatile vapor carrying the effective components of the medicinal materials generated inside the inner tank rises to the top and enters the inlet of the condenser through the pipeline. The vapor flows through the cooling channel inside the condenser and exchanges heat with the cooling medium generated by the refrigeration compressor pump, rapidly cooling down and liquefying into liquid. The liquefied mixture of essential oil and water flows out from the condenser outlet and enters the oil-water separator. Inside the oil-water separator, the mixture naturally separates into layers using the density difference between oil and water and the principle of gravity sedimentation, ultimately achieving the separation and collection of essential oil and water. Meanwhile, the heat generated by the refrigeration compressor pump during the refrigeration process can enter the inner cavity of the heat-insulating water heater, and work together with the electric heating wire in the heat-insulating water heater to heat the water, thereby achieving the purpose of energy-saving utilization of the refrigeration compressor pump. The can lid assembly includes an outer can lid, an opening and closing cylinder, a steam inlet, and an inner can lid. A fixed rotating arm is fixed to the bottom of the outer wall of the outer can body, and a movable rotating arm is fixed to the outer side wall of the outer can lid. The movable rotating arm is screwed to the fixed rotating arm. A fixed rotating seat is fixed to the inner frame at the bottom of the bracket, and a movable rotating seat is fixed to the outer wall at the bottom of the outer can cover. The top of the main body of the opening and closing cylinder is screwed to the fixed rotating seat, and the push rod head of the opening and closing cylinder is screwed to the movable rotating seat. The movement of the opening and closing cylinder push rod enables the outer can cover and the moving rotating arm to rotate relative to the fixed rotating arm, thereby forming the opening and closing action of the outer can cover; The inner can lid is fixed to the inner cavity of the outer can lid. The space between the inner wall of the outer can lid and the outer wall of the inner can lid is filled with heat insulation material. The steam inlet passes through the cavity wall of the outer can lid and communicates with the inner cavity of the inner can lid. Steam can enter the inner cavity of the inner can lid through the steam inlet. The inner cavity of the inner can lid has a steam distribution plate evenly distributed. The micro-holes in the steam distribution plate can disperse the steam that enters the inner can lid through the steam inlet, making the steam entering the inner can more uniform. The bottom wall of the inner tank cover is also connected to a normally closed wastewater discharge port, which extends downward after passing through the cavity wall of the outer tank cover. After distillation is complete, the residue can be discharged by opening the outer tank lid; After distillation, external water pipes can be inserted into each feeding channel to drive the rotation of the receiving plate with the help of the bushing. When the steam inlet is shut off, the top surface of the receiving plate can be cleaned. The cleaning wastewater and condensate can be discharged through the wastewater discharge port.

[0009] By adopting the above technical solution, the present invention can achieve the following beneficial effects: (1) The present invention cleverly decouples the unloading cylinder from the rotation of the bushing by rotating the bottom end of the push rod of the unloading cylinder with the key shaft and preventing it from detaching. This allows the key shaft and the receiving plate to rotate with the bushing during the feeding or extraction process, while the push rod of the unloading cylinder slides axially relative to the cylinder body without relative rotation. This design solves the problem of wear and leakage of internal seals caused by the unloading cylinder being forced to rotate with the bushing in the traditional structure. Especially in the high temperature and high humidity distillation and extraction environment, this structure effectively protects the core components of the unloading cylinder, greatly reduces the failure rate and maintenance cost, and ensures the long-term reliability of the device. (2) The present invention, in conjunction with the fixed-point suspension of the bushing, utilizes the axial limiting characteristics of the lifting guide wheel in the lifting guide groove to construct a reaction force unloading logic. During unloading, the push rod of the unloading cylinder pushes downward against the limited key shaft, and uses the generated reaction force to push the cylinder flange and the cylinder body of the unloading cylinder to move upward. Then, the connecting rod mechanism pulls the receiving plate to flip and unload. This design uses only a single set of unloading cylinders to realize the synchronous flipping action of the receiving plates of different layers, and the structure is extremely compact. At the same time, the method of using the active thrust of the unloading cylinder to push the receiving plate to flip has a greater opening force and more decisive action, effectively avoiding the slag jamming and realizing a fast and thorough slag discharge operation.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0015] Example 1: Examples of the present invention for the addition, automatic spreading, and automatic unloading of Chinese medicinal materials in each layer of receiving plate 723 during the distillation process are shown in 1-14. The distillation tank 2 is used for steam extraction and distillation. The inner wall of the distillation tank 2 is provided with spreading rakes 205. The bushing 702 is screwed to the middle of the top of the distillation tank 2. The middle of the lower inner end of the distillation tank 2 is fixed with a central shaft 708. The outer cylindrical surface of the central shaft 708 is evenly provided with lifting guide grooves 719. The middle of the bushing 702 is slidably and rotatably fitted with a bearing sleeve 710. The middle of the bearing sleeve 710 is screwed with a cylinder flange 709. The top of the cylinder flange 709 is fixed with a discharge cylinder 706. The bottom end of the bushing 702 is slidably inserted with a key shaft 713. The bottom end of the push rod of the discharge cylinder 706 is screwed with the key shaft 713 and cannot be detached. The bottom end of the key shaft 713 is symmetrically fixed with a support rod fixing block 716 and an outer fixed column 717, and the support rod fixing block 716 and the outer fixed column 717 form a hollow cylindrical structure. This hollow cylindrical structure can rotate with the central fixed shaft 708 as a reference. Lifting guide wheels 720 are evenly screwed onto the inner circular surface of the outer fixed column 717, and the lifting guide wheels 720 of the same layer are rolled in the lifting guide groove 719. The external drive mechanism can drive the bushing 702 to rotate automatically. After the bushing 702 rotates, it can drive the support rod fixing block 716 and the outer fixed column 717, which are fixed to the key shaft 713, to rotate through the sliding insertion and cooperation with the key shaft 713. At this time, the lifting guide wheel 720 on the inner circular surface of the outer fixed column 717 forms a rolling connection with the lifting guide groove 719, which can drive the support rod fixing block 716 and the outer fixed column 717 to reciprocate synchronously within a certain range as the bushing 702 rotates, guided by the lifting path of the lifting guide groove 719. Each set of support rod fixing blocks 716 has a support rod 722 vertically slidably inserted into the grooves on both sides of the main body, and the top end of the support rod 722 is fixedly connected to the bottom end of the bearing sleeve 710. Because the bottom end of the push rod of the unloading cylinder 706 is securely screwed to the top end of the key shaft 713 and cannot be disengaged, and the key shaft 713 can perform a combined action of rotation and reciprocating lifting as the bushing 702 rotates and the support rod fixing block 716 and the outer fixed column 717 reciprocate. However, the main body of the unloading cylinder 706 is fixed to the cylinder flange 709, and the bottom end of the cylinder flange 709 is screwed to the bearing sleeve 710. The bottom end of the bearing sleeve 710 is fixed to the support rod 722. Therefore, without rotating the cylinder flange 709 and the unloading cylinder 706, the main body of the unloading cylinder 706 and the push rod are passively raised and lowered synchronously. The purpose is to keep the relative vertical position of the support rod 722 and the support rod fixing block 716 unchanged when the push rod of the unloading cylinder 706 does not move actively. The fan-shaped support plates 723 are arranged in a relatively hinged structure and are evenly and laterally screwed to different height positions on the outer circular surface of the outer fixed column 717. The bottom of each set of support plates 723 is screwed with a rotating connecting rod 730. A tie rod 732 is arranged and screwed between the support rods 722 on each side. A support rod 728 is arranged and screwed in the support rod fixing block 716 on each side. The top of the support rod 728 on the same side, the bottom of the rotating connecting rod 730, and the outer end of the tie rod 732 are screwed together. Furthermore, both the main body of the support rod fixing block 716 and the support rod 722 are provided with long slots to eliminate interference with the support rod 728 and the tie rod 732; With the bushing 702 stopped rotating, after the push rod of the unloading cylinder 706 pushes the key shaft 713 downwards, the key shaft 713 is fixedly connected to the support rod fixing block 716 and the outer fixed column 717. The lifting guide wheel 720 on the inner surface of the outer fixed column 717 does not move relative to the lifting guide groove 719. Therefore, when the push rod of the unloading cylinder 706 cannot push the key shaft 713 downwards, the key shaft 713 becomes a fixed reference, which will drive the unloading cylinder 706 itself to move upwards, unloading... The upward movement of the material cylinder 706 will cause the top cylinder flange 709 to move upward. The bottom end of the cylinder flange 709 is screwed into the bearing sleeve 710 and will not detach from the bearing sleeve 710. Therefore, when the bearing sleeve 710 moves upward, it will drive the support rod 722 to move upward. When the support rod 722 moves upward, it will drive the pull rod 732 to move upward. The pull rod 732 pulls the screw joint of the support rod 728 and the rotating connecting rod 730 upward, forming the downward flipping action of the relatively hinged receiving plate 723. The working principle is as follows: The feeding and spreading of Chinese medicinal materials: The side wall of the distillation tank 2 is obliquely opened with a feeding port that is directly opposite to each layer of receiving plate 723, so that Chinese medicinal materials can be quantitatively added to the top surface of each layer of receiving plate 723 in the unfolded state. Then, the rotation drive mechanism of bushing 702 is activated, causing bushing 702 to rotate around the center axis of distillation tank 2. Bushing 702 drives key shaft 713 to rotate synchronously through sliding fit. Key shaft 713 drives the rotation of support rod fixing block 716 and outer fixed column 717 fixed to it. At this time, the lifting guide wheel 720 installed in the inner circular surface of outer fixed column 717 is embedded in the lifting guide groove 719 opened in the middle fixed shaft 708. With the rotation, the lifting guide wheel 720 is forced to move along the trajectory of lifting guide groove 719, transforming the single rotation motion of bushing 702 into a compound motion of rotation and reciprocating lifting of support rod fixing block 716 and outer fixed column 717. This causes the receiving plate 723 to perform slight up and down shaking while rotating. This compound motion, combined with the raking action of spreading rake 205 on the inner wall of distillation tank 2, causes the Chinese medicinal materials to continuously roll and shift on the top surface of receiving plate 723, eventually achieving uniform flatness. This ensures good air permeability of the medicinal material layer and provides the best stacking state for subsequent extraction. After the medicinal materials are laid out, the distillation and extraction stage begins. Each layer of the receiving plate 723 has micropores that allow only steam to pass through. High-temperature steam enters from the bottom of the distillation tank 2, passes through the layers of Chinese medicinal materials on each layer of the receiving plate 723, and carries volatile components to rise into the condensation system. During the extraction process, in order to achieve further uniform heating, the receiving plate 723 continues to rotate slowly and move up and down slightly. After distillation and extraction, the Chinese medicinal materials are unloaded. After extraction, the medicinal materials become dregs and need to be discharged. At this time, the bushing 702 stops rotating and stops at a fixed point. The lifting guide wheel 720 on the inner circular surface of the outer fixed column 717 stops at a specific position in the lifting guide groove 719 (usually the lower stop or the locking position), so that the key shaft 713 is relatively fixed. When the unloading cylinder 706 is activated, the control push rod extends downward and abuts against the top of the key shaft 713. Since the key shaft 713 is already limited by the cooperation of the lifting guide wheel 720 and the lifting guide groove 719, it cannot move downward. According to the principle of mechanical reaction force, the key shaft 713 generates an upward reaction force on the unloading cylinder 706. This reaction force pushes the unloading cylinder 706 to move upward against the weight of the cylinder body, thereby driving the cylinder flange 709, bearing sleeve 710 and support rod 722 to move upward synchronously. The support rod 722 pulls the tie rod 732 to move upward. The tie rod 732, as the active component, pulls the support rod 728 and the rotating connecting rod 730 to move through the same rotating joint point, thereby causing the receiving plate 723 to flip downward and open around the hinge point on the outer circular surface of its connection with the outer fixed column 717, forming an inverted V shape. The moist dregs fall off rapidly under the action of gravity and are discharged through the normally closed outlet at the bottom of the distillation tank 2, completing the unloading. After unloading, the push rod of the unloading cylinder 706 retracts, all components are reset, the receiving plate 723 closes, and it is ready to enter the next batch of feeding.

[0016] The specific structure of distillation jar 2 is as follows: Figure 2 As shown, the outer wall of the inner tank 202 and the inner wall of the outer tank 201 are fixedly connected to each other, forming the tank structure of the distillation tank 2. The inner tank 202 has a feeding channel 203 arranged and connected in the side wall. The feeding channel 203 extends outward through the main body of the outer tank 201. The rubber plug 204 is inserted into the feeding channel 203 with an interference fit to achieve a seal during distillation; The spreading rakes 205 are arranged and fixed on the inner wall of the inner tank 202; A support 1 is also provided on the outside of the distillation tank 2. The outer wall of the outer tank body 201 is snapped and fixed to the inner frame of the support 1 to support the distillation tank 2.

[0017] The specific structure of the medicinal herb receiving component 7 is as follows: Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the rotating base 701 is installed and fixed in the middle of the top wall of the outer tank 201 and the inner tank 202, and the bushing 702 is screwed into the rotating base 701; a servo motor 703 is installed and fixed on the top of the bracket 1, and a drive gear 704 is fixed in the output shaft of the servo motor 703. A rotating gear 705 is fitted on the top of the bushing 702, and the rotating gear 705 meshes with the drive gear 704. The servo drive system formed by the servo motor 703 can drive the bushing 702 to rotate slowly at a certain speed, and can make the bushing 702 stop at a fixed point. The bottom of the inner tank 202 is fixed with a base frame 707, and the bottom of the central fixed shaft 708 is fixed to the middle of the base frame 707. The bearing sleeve 710 has a bearing 711 inside. The outer ring of the bearing 711 is fixed in the stepped hole inside the bearing sleeve 710. The inner ring of the bearing 711 is fixedly connected to the bottom of the cylinder flange 709, which enables the cylinder flange 709 to rotate freely with low resistance relative to the bearing sleeve 710. Universal joint 712 is installed between the bottom end of the push rod of unloading cylinder 706 and the top end of key shaft 713. It allows key shaft 713 to rotate freely around the push rod of unloading cylinder 706 when key shaft 713 rotates with bushing 702. This means that when unloading cylinder 706 does not have an active action, its push rod and cylinder body can only have axial linear movement, avoiding the wear, jamming and air leakage problems of internal seals caused by unloading cylinder 706 being forced to rotate. Furthermore, when the receiving plate 723 is flipped over for unloading, the weight of the material and the receiving plate 723 itself will generate an eccentric torque. The universal joint 712 can adaptively adjust the angle to absorb installation errors and eccentric forces, ensuring accurate transmission of thrust and preventing the push rod of the unloading cylinder 706 from bending. Meanwhile, when the push rod of the unloading cylinder 706 pushes down against the key shaft 713 to unload in a reaction force manner, the universal joint 712 can also provide flexible buffering to avoid mechanical impact when the rigid connection is subjected to force, making the flipping action of the receiving plate 723 more stable and smooth.

The outer guardrail 725 is connected to the outer side of the top surface of the receiving plate 723, and the inner sheath 726 is connected to the inner side of the top surface of the receiving plate 723. After the two sets of receiving plates 723 are flipped up and unfolded into place, the outer guardrail 725 and the inner sheath 726 are joined together, forming a protective boundary for the inner and outer sides of the receiving plate 723, providing a flat and safe platform for laying Chinese medicinal materials. The main body of the support rod fixing block 716 is provided with a first clearance groove 733. Each set of support rod sliding grooves 721 is provided with a second clearance groove 734 that communicates with the first clearance groove 733.

A fixed rotating seat 802 is fixed to the bottom inner frame of the bracket 1, and a movable rotating seat 804 is fixed to the bottom outer wall of the outer can cover 801. The top of the main body of the opening and closing cylinder 803 is screwed to the fixed rotating seat 802, and the push rod head of the opening and closing cylinder 803 is screwed to the movable rotating seat 804. The movement of the push rod of the opening and closing cylinder 803 can cause the outer can cover 801 and the moving rotating arm 806 to rotate relative to the fixed rotating arm 805, thereby forming the opening and closing action of the outer can cover 801.

The micro-holes in the steam distribution plates 809 can disperse the steam that enters the inner can cover 808 through the steam inlet 807, making the steam entering the inner can 202 more uniform. The bottom wall of the inner tank cover 808 is also connected to a normally closed wastewater discharge port 810, which extends downward after passing through the cavity wall of the outer tank cover 801. After distillation is complete, the residue can be discharged by opening the outer tank cover 801; After distillation, an external water pipe can be inserted into each feeding channel 203. The bearing plate 723 can be rotated in conjunction with the bushing 702. When the steam inlet 807 is shut off, the top surface of the bearing plate 723 can be cleaned. The cleaning wastewater and condensate can be discharged through the wastewater discharge port 810.

[0019] Example 2: Examples of the specific processes of distillation and condensation in this invention Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown; The heat-insulating water heater 302 in the tank insulation component 3 is fixedly installed at the bottom of the outer wall of the outer tank 201 by the support 301. The top outlet of the heat-insulating water heater 302 is connected to the circulating water pump 303. The cavity wall of the outer tank 201 is connected to the outlet of the circulating water pump 303 by the liquid inlet pipe 304. The bottom inlet of the heat-insulating water heater 302 is connected to the top of the outer wall of the outer tank 201 by the liquid return pipe 305. The heat-insulating water heater 302 is equipped with an electric heating wire and can be filled with sufficient water. The heated water in the heat-insulating water heater 302 can be pumped by the circulating water pump 303 to the cavity between the inner wall of the outer tank 201 and the outer wall of the inner tank 202, and then flow back into the heat-insulating water heater 302 to achieve the purpose of heat preservation of the interior of the inner tank 202. The condenser 402 in the condensation assembly is fixedly installed on the upper part of the outer wall of the outer tank 201 by the bracket 401. The inlet of the condenser 402 passes through the cavity wall of the outer tank 201 and communicates with the inner top of the inner tank 202. The outlet of the condenser 402 is connected to the oil-water separator 6, which is fixedly installed on the bracket 1. The cold air outlet of the refrigeration compressor pump 5 is connected to the condenser assembly 4, and the hot air outlet is connected to the cavity wall of the heat-insulating water heater 302. Using a refrigeration compressor pump 5 to drive the refrigeration cycle and condensing heat through a condenser 402 is the most basic thermodynamic cycle principle in the field of refrigeration and heat pump technology. The condenser 402, as the standard heat exchange component of this cycle, has a structure (such as disc type or plate type) and a connection method with the refrigeration compressor pump 5 and the inner tank 202 that are common knowledge that can be directly selected by those skilled in the art without creative labor. The oil-water separator 6 utilizes the principle of gravity separation based on the density difference between oil and water, which is a classic liquid-liquid separation technology in chemical unit operations. In existing essential oil extraction or distillation equipment, the oil-water separator 6 is connected in series after the condenser 402 as a standard process configuration. The specific structure of the oil-water separator 6 (such as having dual oil and water outlets, viewing windows, etc.) are all commercially available standard parts and belong to the extremely mature existing technology in this field. During the distillation and extraction process, the high-temperature volatile vapor carrying the effective components of the medicinal materials generated inside the inner tank 202 rises to the top and enters the inlet of the condenser 402 through the pipeline. The vapor flows through the cooling channel inside the condenser 402 and exchanges heat with the cooling medium generated by the refrigeration compressor pump 5, which rapidly cools down and liquefies into liquid. The liquefied mixture of essential oil and water flows out from the outlet of the condenser 402 and enters the oil-water separator 6. Inside the oil-water separator 6, the mixture naturally separates into layers by utilizing the density difference between oil and water and the principle of gravity sedimentation, thus achieving the separation and collection of essential oil and water. Meanwhile, the heat generated by the refrigeration compressor pump 5 during the refrigeration process can enter the inner cavity of the heat preservation water heater 302, and work together with the electric heating wire in the heat preservation water heater 302 to heat the water for heat preservation, so as to achieve the purpose of energy-saving utilization of the refrigeration compressor pump 5.
