AI Technical Summary
In molecular distillation equipment, evaporating molecules tend to fall back onto the heating surface or the inner wall of the equipment during long-distance transport, resulting in low condensation efficiency. Existing booster devices have poor stability and high energy consumption in high vacuum environments, making it difficult to improve evaporation efficiency.
The device employs a propulsion mechanism driven by shape memory metal wires. Temperature changes cause the shape memory metal wires to deform, which in turn drives the propulsion mechanism to rotate. The device also utilizes nozzles and bends to create directional airflow, which assists the evaporation molecules in moving toward the condenser. Combined with the cooler, this controls the temperature and reduces energy consumption.
It significantly reduces the phenomenon of evaporating molecules falling back, improves distillation efficiency, reduces energy consumption and maintenance costs, and enhances operational stability.

Abstract
Description
Technical Field
[0001] This invention relates to the field of molecular distillation equipment technology, specifically to a molecular distillation device with a gas-propellant device. Background Technology
[0002] Molecular distillation technology, with its ability to achieve efficient separation under low temperature and high vacuum conditions, is widely used in the purification processes of high-value-added materials. As industrial production demands higher throughput, molecular distillers have become mainstream equipment due to their larger evaporation area and stronger material handling capacity. However, a key drawback of these devices is the significantly increased transport path of the evaporated molecular gas: after evaporation on the heating surface to form molecular gas, the material must travel a longer distance to reach the condenser surface. During this process, some molecules, due to kinetic energy loss, interference from weak airflow within the equipment, or their own gravity, are prone to falling back to the heating surface or the inner wall of the equipment, unable to participate in condensation and separation. This fallback phenomenon is particularly prominent in distillation equipment with long transport paths, directly leading to a reduction in the number of effectively condensed molecules and severely restricting the improvement of distillation efficiency.
[0003] To address these issues, the industry has attempted to enhance the transport capacity of molecular gases by increasing vacuum levels and optimizing heating temperature distribution. However, these methods have yielded limited results and are prone to causing new problems such as increased energy consumption and thermal decomposition of materials. Some devices employ simple flow-guiding structures to assist molecular transport, but these cannot actively and effectively propel the molecular gases, making it difficult to specifically address the problem of sag during long-stroke distillations. Furthermore, traditional propulsion devices driven by motors require complex sealing structures adapted to high-vacuum environments, and their driving stability is easily affected by temperature fluctuations during distillation, making it difficult to continuously provide reliable support for long-distance molecular gas transport. This has resulted in the evaporation efficiency of molecular stills remaining at a bottleneck. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are:
[0023] This molecular distillation equipment with a gas-assisted propulsion device specifically addresses the core problem of molecules in the distillation vessel easily falling back midway due to their long travel distance and failing to effectively reach the condenser surface. The drive structure utilizes shape memory metal wires that deform with temperature changes, combined with the temperature control function of the cooler to achieve stable power output. This power is reliably transmitted through driven wheels, drive gears, and driven gears to rotate the propulsion device. The circular array of nozzles and bends on the propulsion device evenly pushes the gas to the inner wall of the distillation tank, forming a directional auxiliary airflow that effectively lifts and guides the evaporating molecules towards the condenser, significantly reducing the phenomenon of molecules falling back midway. Simultaneously, the shape memory metal wire drive replaces the traditional motor drive, making it more suitable for the temperature environment of the distillation process. It eliminates the need for complex sealing structures, reducing energy consumption and maintenance costs, and significantly improving the overall evaporation efficiency and operational stability of the molecular distillation equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0030] Please see Figures 1-3The present invention provides a technical solution: a molecular distillation device with a gas-assisted device, which is mounted on a distillation tank 1. The bottom of the distillation tank 1 is connected to a drive structure 2. A feed pipe 13 is connected to the distillation tank 1 and passes through the drive structure 2. A fixed rotating shaft 11 is provided on the distillation tank 1 for fixing the top of the push device 3. A discharge pipe 12 is also provided on the distillation tank 1 for discharging distillation cooling liquid.
[0031] After the material enters the distillation tank 1 through the feed pipe 13, the drive structure 2 connected to the bottom of the distillation tank 1 is activated. The temperature of the inner wall of the feed pipe 13 is affected by physical factors and rises, which in turn affects the temperature of the shape memory metal wire 27 near the feed pipe 13. When the temperature of the shape memory metal wire 27 rises, the cooler 26 cools the other end of the shape memory metal wire 27, making the temperatures of the two ends of the shape memory metal wire 27 inconsistent. The tension of the shape memory metal wire 27 changes, and the internal shape memory metal wire 27 deforms due to the temperature to generate driving force, which drives the push device 3 connected to it to operate. At the same time, the fixed rotating shaft 11 on the distillation tank 1 fixes the top of the push device 3 to ensure its rotational stability. During the rotation, the push device 3 directionally pushes the gas to the vicinity of the inner wall of the distillation tank 1, providing auxiliary thrust for the evaporation molecules, effectively solving the problem of easy fall back midway due to the long stroke, and helping the evaporation molecules to reach the condenser surface smoothly to complete the separation. Finally, the coolant produced by distillation is discharged through the discharge pipe 12 on the distillation tank 1.
[0032] Please see Figure 4 The pushing device 3 is located in the distillation tank 1. The pushing device 3 is used to push the gas onto the inner wall of the distillation tank 1. Since the temperature of the inner wall of the distillation tank 1 is lower than the internal temperature, pushing the gas onto the inner wall can accelerate the distillation efficiency. The pushing device 3 is equipped with a spray pipe 31, one end of which has an elbow 32. The spray pipe 31 and elbow 32 are arranged in a circular array on the pushing device 3. The pushing device 3 is connected to the feed pipe 13. The pushing device 3 rotates under the drive of the driving structure 2. The pushing device 3 throws the gas onto the inner wall of the distillation tank 1 through the spray pipe 31 and the elbow 32. The gas flow passes through the elbow 32 and is then ejected, providing sufficient rotational power for the pushing device 3 to rotate within the distillation tank 1. The upper and lower ends of the pushing device 3 are connected by a fixed rotating shaft 11, ensuring that the pushing device 3 can rotate within the distillation tank 1.
[0033] The driving device 3 is located inside the distillation tank 1 and is connected to the feed pipe 13. The upper and lower ends are connected by a fixed rotating shaft 11 to ensure rotational stability. It rotates under the drive of the driving structure 2. The driving device 3 has a ring array of ejector pipes 31, and each ejector pipe 31 has a bend 32 at one end. During rotation, the ejector pipes 31 use the bends 32 to throw the gas onto the inner wall of the distillation tank 1. At the same time, when the gas flows through the bends 32 and is ejected, it provides rotational power to the driving device 3, thus achieving the effect of accelerating the distillation efficiency.
[0034] The drive structure 2 is connected to the push device 3. The drive structure 2 drives the push device 3, enabling it to rotate. The drive structure 2 includes a shape memory metal wire 27. The shape memory metal wire 27 deforms and stretches when exposed to temperature, while the cooled side of the shape memory metal wire 27 shortens, thereby driving the drive wheel 28 and the driven wheel 23 to rotate. The end of the shape memory metal wire 27 near the drive wheel 28 enters the heating container connected to the bottom of the distillation tank 1. The shape memory metal wire 27 deforms due to temperature. The drive structure 2 includes a driven shaft 211 mounted on the feed pipe 13, which drives a driven gear 21 to rotate. The driven shaft 211 is connected to the driven gear 21, and the driven shaft 211 is connected to the drive structure 3. The rotation of the driven gear 21 drives the drive structure 3 to rotate. The drive structure 2 also includes a support plate 25 mounted on peripheral equipment. The support plate 25 is used to connect to other peripheral equipment. A driven wheel 23 and a drive wheel 28 are connected to the support plate 25. 28 is used to connect the memory metal wire 27, ensuring that one end of the memory metal wire 27 can be stably placed in the heating container. The driven wheel 23 and the power wheel 28 are located at both ends of the support plate 25, and the memory metal wire 27 is sleeved on the driven wheel 23 and the power wheel 28. A cooler 26 is sleeved on the outside of the memory metal wire 27. The cooler 26 is used to cool the memory metal wire 27 and enhance the rotation of the memory metal wire 27. The upper and lower ends of the cooler 26 are provided with limiting sleeves 261. The outside of the cooler 26 is provided with a filling inlet 262 for filling the cooler. Coolant is filled into the 26. One end of the driven wheel 23 is provided with a first mounting shaft 24, which is connected to the support plate 25. One end of the power wheel 28 is provided with a second mounting shaft 29, which is connected to the support plate 25. One end of the driven wheel 23 is connected to a drive gear 22. The driven wheel 23 and the power wheel 28 will rotate under the influence of the memory metal wire 27, thereby driving the drive gear 22 to rotate. The drive gear 22 drives the driven gear 21 to rotate, and the drive gear 22 and the driven gear 21 mesh.
[0035] The drive structure 2 is connected to the push device 3. When it is working, the end of the shape memory metal wire 27 near the power wheel 28 is placed in the heating container at the bottom of the distillation tank 1 and deformed and stretched by heat. At the same time, the cooler 26 sleeved on the outside injects coolant through the inlet 262 and is limited and fixed by the limiting sleeve 261, which cools the other side of the shape memory metal wire 27 and shortens it. This drives the driven wheel 23 and the power wheel 28 sleeved with the shape memory metal wire 27 to rotate. The two are mounted on the bearing plate 25 of the peripheral equipment through the first mounting shaft 24 and the second mounting shaft 29. The drive gear 22 connected to one end of the driven wheel 23 rotates with the driven wheel 23. Since the drive gear 22 meshes with the driven gear 21 connected to the driven shaft 211 on the feed pipe 13, the drive gear 22 drives the driven gear 21 and the driven shaft 211 to rotate, which finally drives the push device 3 connected to the driven shaft 211 to rotate.
[0036] In the first embodiment, a molecular distillation apparatus with a gas-assisted device is provided on a distillation tank 1. The bottom of the distillation tank 1 is connected to a drive structure 2. A feed pipe 13 is connected to the distillation tank 1 and passes through the drive structure 2. A fixed rotating shaft 11 is provided on the distillation tank 1 for fixing the top of the push device 3. A discharge pipe 12 is also provided on the distillation tank 1 for discharging distillation cooling liquid.
[0037] The pushing device 3 is located in the distillation tank 1. The pushing device 3 is used to push the gas to the inner wall of the distillation tank 1 to accelerate the distillation efficiency. The pushing device 3 is equipped with a spray pipe 31, and one end of the spray pipe 31 is equipped with a bend 32. The spray pipe 31 and the bend 32 are arranged in a ring array on the pushing device 3. The pushing device 3 is connected to the feed pipe 13. The pushing device 3 is driven by the driving structure 2 to rotate. The pushing device 3 throws the gas to the inner wall of the distillation tank 1 through the spray pipe 31 and the bend 32. Since the airflow passes through the bend 32 and then sprays out, it provides a certain rotational power for the rotation of the pushing device 3. The pushing device 3 rotates in the distillation tank 1. The upper and lower ends of the pushing device 3 are connected by a fixed rotating shaft 11 to ensure that the pushing device 3 can rotate in the distillation tank 1.
[0038] The driving device 3 is located inside the distillation tank 1 and is connected to the feed pipe 13. The upper and lower ends are connected by a fixed rotating shaft 11 to ensure rotational stability. It rotates under the drive of the driving structure 2. The driving device 3 has a ring array of ejector pipes 31, and each ejector pipe 31 has a bend 32 at one end. During rotation, the ejector pipes 31 use the bends 32 to throw the gas onto the inner wall of the distillation tank 1. At the same time, when the gas flows through the bends 32 and is ejected, it provides rotational power to the driving device 3, thus achieving the effect of accelerating the distillation efficiency.
[0039] In the second embodiment, a molecular distillation apparatus with a gas-assisted device is provided on a distillation tank 1. The bottom of the distillation tank 1 is connected to the drive structure 2. A feed pipe 13 is connected to the distillation tank 1 and passes through the drive structure 2. A fixed rotating shaft 11 is provided on the distillation tank 1 for fixing the top of the push device 3. A discharge pipe 12 is also provided on the distillation tank 1 for discharging the distillation coolant.
[0040] Drive structure 2 is connected to push device 3. Drive structure 2 drives push device 3 to rotate. Drive structure 2 includes shape memory metal wire 27. Shape memory metal wire 27 deforms and stretches when exposed to temperature. The shape memory metal wire 27 shortens when cooled on the other side, thereby driving drive wheel 28 and driven wheel 23 to rotate. The end of shape memory metal wire 27 near drive wheel 28 enters the heating container connected to the bottom of distillation tank 1. Shape memory metal wire 27 deforms due to temperature. The drive structure 2 includes a driven shaft 211 mounted on the feed pipe 13, which drives a driven gear 21 to rotate. The driven shaft 211 is connected to the driven gear 21, and the driven shaft 211 is connected to the drive device 3. The rotation of the driven gear 21 drives the drive device 3 to rotate. The drive structure 2 also includes a support plate 25 mounted on peripheral equipment. The support plate 25 is used to connect to other peripheral equipment. A driven wheel 23 and a power wheel 28 are connected to the support plate 25. Wheel 28 is used to connect the shape memory metal wire 27, ensuring that one end of the shape memory metal wire 27 can be stably placed in the heating container. Driven wheel 23 and drive wheel 28 are located at both ends of the support plate 25, and the shape memory metal wire 27 is sleeved on the driven wheel 23 and drive wheel 28. A cooler 26 is sleeved on the outside of the shape memory metal wire 27. The cooler 26 is used to cool the shape memory metal wire 27 and enhance the rotation of the shape memory metal wire 27. Limiting sleeves 261 are provided at both the upper and lower ends of the cooler 26. An inlet 262 is provided on the outside of the cooler 26 for filling the cooler. Coolant is filled into the device 26. One end of the driven wheel 23 is provided with a first mounting shaft 24, which is connected to the support plate 25. One end of the power wheel 28 is provided with a second mounting shaft 29, which is connected to the support plate 25. One end of the driven wheel 23 is connected to a drive gear 22. The driven wheel 23 and the power wheel 28 will rotate under the influence of the memory metal wire 27, thereby driving the drive gear 22 to rotate. The drive gear 22 drives the driven gear 21 to rotate, and the drive gear 22 and the driven gear 21 mesh.
[0041] The drive structure 2 is connected to the push device 3. When it is working, the end of the shape memory metal wire 27 near the power wheel 28 is placed in the heating container at the bottom of the distillation tank 1 and deformed and stretched by heat. At the same time, the cooler 26 sleeved on the outside injects coolant through the inlet 262 and is limited and fixed by the limiting sleeve 261, which cools the other side of the shape memory metal wire 27 and shortens it. This drives the driven wheel 23 and the power wheel 28 sleeved with the shape memory metal wire 27 to rotate. The two are mounted on the bearing plate 25 of the peripheral equipment through the first mounting shaft 24 and the second mounting shaft 29. The drive gear 22 connected to one end of the driven wheel 23 rotates with the driven wheel 23. Since the drive gear 22 meshes with the driven gear 21 connected to the driven shaft 211 on the feed pipe 13, the drive gear 22 drives the driven gear 21 and the driven shaft 211 to rotate, which finally drives the push device 3 connected to the driven shaft 211 to rotate.
[0042] In the third embodiment, after the material enters the distillation tank 1 through the feed pipe 13, the drive structure 2 connected to the bottom of the distillation tank 1 is activated. The internal shape memory metal wire 27 deforms due to temperature to generate driving force, which drives the push device 3 connected to it to operate. At the same time, the fixed rotating shaft 11 on the distillation tank 1 fixes the top of the push device 3 to ensure its rotational stability. During the rotation, the push device 3 directionally pushes the gas to the vicinity of the inner wall of the distillation tank 1, providing auxiliary thrust for the evaporation molecules, effectively solving the problem that the gas is prone to falling back midway due to its long journey, and helping the evaporation molecules to smoothly reach the surface of the condenser to complete the separation. Finally, the coolant produced by distillation is discharged through the discharge pipe 12 on the distillation tank 1.
[0043] The pushing device 3 is located in the distillation tank 1. The pushing device 3 is used to push the gas to the inner wall of the distillation tank 1 to accelerate the distillation efficiency. The pushing device 3 is equipped with a spray pipe 31, and one end of the spray pipe 31 is equipped with a bend 32. The spray pipe 31 and the bend 32 are arranged in a ring array on the pushing device 3. The pushing device 3 is connected to the feed pipe 13. The pushing device 3 is driven by the driving structure 2 to rotate. The pushing device 3 throws the gas to the inner wall of the distillation tank 1 through the spray pipe 31 and the bend 32. Since the airflow passes through the bend 32 and then sprays out, it provides a certain rotational power for the rotation of the pushing device 3. The pushing device 3 rotates in the distillation tank 1. The upper and lower ends of the pushing device 3 are connected by a fixed rotating shaft 11 to ensure that the pushing device 3 can rotate in the distillation tank 1.
[0044] The driving device 3 is located inside the distillation tank 1 and is connected to the feed pipe 13. The upper and lower ends are connected by a fixed rotating shaft 11 to ensure rotational stability. It rotates under the drive of the driving structure 2. The driving device 3 has a ring array of ejector pipes 31, and each ejector pipe 31 has a bend 32 at one end. During rotation, the ejector pipes 31 use the bends 32 to throw the gas onto the inner wall of the distillation tank 1. At the same time, when the gas flows through the bends 32 and is ejected, it provides rotational power to the driving device 3, thus achieving the effect of accelerating the distillation efficiency.
[0045] Drive structure 2 is connected to push device 3. Drive structure 2 drives push device 3 to rotate. Drive structure 2 includes shape memory metal wire 27. Shape memory metal wire 27 deforms and stretches when exposed to temperature. The shape memory metal wire 27 shortens when cooled on the other side, thereby driving drive wheel 28 and driven wheel 23 to rotate. The end of shape memory metal wire 27 near drive wheel 28 enters the heating container connected to the bottom of distillation tank 1. Shape memory metal wire 27 deforms due to temperature. The drive structure 2 includes a driven shaft 211 mounted on the feed pipe 13, which drives a driven gear 21 to rotate. The driven shaft 211 is connected to the driven gear 21, and the driven shaft 211 is connected to the drive device 3. The rotation of the driven gear 21 drives the drive device 3 to rotate. The drive structure 2 also includes a support plate 25 mounted on peripheral equipment. The support plate 25 is used to connect to other peripheral equipment. A driven wheel 23 and a power wheel 28 are connected to the support plate 25. Wheel 28 is used to connect the shape memory metal wire 27, ensuring that one end of the shape memory metal wire 27 can be stably placed in the heating container. Driven wheel 23 and drive wheel 28 are located at both ends of the support plate 25, and the shape memory metal wire 27 is sleeved on the driven wheel 23 and drive wheel 28. A cooler 26 is sleeved on the outside of the shape memory metal wire 27. The cooler 26 is used to cool the shape memory metal wire 27 and enhance the rotation of the shape memory metal wire 27. Limiting sleeves 261 are provided at both the upper and lower ends of the cooler 26. An inlet 262 is provided on the outside of the cooler 26 for filling the cooler. Coolant is filled into the device 26. One end of the driven wheel 23 is provided with a first mounting shaft 24, which is connected to the support plate 25. One end of the power wheel 28 is provided with a second mounting shaft 29, which is connected to the support plate 25. One end of the driven wheel 23 is connected to a drive gear 22. The driven wheel 23 and the power wheel 28 will rotate under the influence of the memory metal wire 27, thereby driving the drive gear 22 to rotate. The drive gear 22 drives the driven gear 21 to rotate, and the drive gear 22 and the driven gear 21 mesh.
[0046] The drive structure 2 is connected to the push device 3. When it is working, the end of the shape memory metal wire 27 near the power wheel 28 is placed in the heating container at the bottom of the distillation tank 1 and deformed and stretched by heat. At the same time, the cooler 26 sleeved on the outside injects coolant through the inlet 262 and is limited and fixed by the limiting sleeve 261, which cools the other side of the shape memory metal wire 27 and shortens it. This drives the driven wheel 23 and the power wheel 28 sleeved with the shape memory metal wire 27 to rotate. The two are mounted on the bearing plate 25 of the peripheral equipment through the first mounting shaft 24 and the second mounting shaft 29. The drive gear 22 connected to one end of the driven wheel 23 rotates with the driven wheel 23. Since the drive gear 22 meshes with the driven gear 21 connected to the driven shaft 211 on the feed pipe 13, the drive gear 22 drives the driven gear 21 and the driven shaft 211 to rotate, which finally drives the push device 3 connected to the driven shaft 211 to rotate.
[0047] When the molecular distillation equipment with a gas-assisted propulsion device is used, after the material enters the distillation tank 1 through the feed pipe 13, the drive structure 2 connected to the bottom of the distillation tank 1 is activated. The end of the memory metal wire 27 inside, near the power wheel 28, is placed in the heating container at the bottom of the distillation tank 1 and deformed and stretched by heat. At the same time, the cooler 26 on the outside is injected with coolant through the inlet 262 and limited and fixed by the limiting sleeve 261, cooling the other side of the memory metal wire 27 and shortening it, thereby driving the driven wheel 23 and the power wheel 28, which are mounted on both ends of the external support plate 25 through the first mounting shaft 24 and the second mounting shaft 29, to rotate. The drive gear 22 connected to one end of the 3 rotates accordingly. Because it meshes with the driven gear 21 connected to the driven shaft 211 on the feed pipe 13, it drives the driven shaft 211 and the push device 3 connected to it to rotate. The push device 3 fixes the upper and lower ends by fixing the shaft 11 to ensure rotational stability. The nozzle 31 arranged in a ring array and the elbow 32 at one end throw the gas to the inner wall of the distillation tank 1 when rotating. At the same time, the airflow is sprayed out through the elbow 32 to provide additional rotational power for the push device 3, thereby assisting the evaporation molecules to reach the surface of the condenser smoothly. Finally, the coolant produced by distillation is discharged through the discharge pipe 12 on the distillation tank 1.
