Description

A bitter almond essential oil purification device Technical Field

[0001] This utility model relates to the field of purification device technology, specifically a bitter almond essential oil purification device. Background Technology

[0002] Bitter almond essential oil is an oily liquid with a unique aroma. Its main component is benzaldehyde. This essential oil can be extracted from bitter almonds, usually using steam distillation. During the extraction process, the essential oil is distilled out with the steam, forming a pale yellow oily liquid. Bitter almond essential oil has wide applications in the cosmetics, food, and paint industries. However, its purification requires the use of a bitter almond essential oil purification device, which is a specialized device that uses water bath heating combined with distillation or molecular distillation techniques to directionally separate and purify benzaldehyde from bitter almond extract.

[0003] Patent document CN217745807U discloses an amygdalin extraction and purification device, which includes "a chassis, a power cord, heat dissipation holes, a controller, a door, a handle, and a pushing device. This invention features a pushing device located at the rear of the chassis. When the door is opened and the motor is turned on, the pushing plate slides outward, pushing out the extracted amygdalin for easy handling by the operator. The device also includes a limiting mechanism inside the pushing plate. When a container is placed on the pushing plate, a sliding cylinder slides via a spring, causing a pad to adhere to the container surface and clamping and limiting the container, preventing collapse."

[0004] However, the aforementioned amygdalin extraction and purification device mainly addresses the issue of clamping and limiting the container to prevent collapse, making it inconvenient to fix the distillation flask during heating and to easily lift and remove it after heating.

[0005] Therefore, it is necessary to develop a safety mechanism that can secure the distillation flask during heating and facilitate its removal after heating is complete. Summary of the Invention

[0006] The purpose of this invention is to provide a bitter almond essential oil purification device to solve the technical problem of improving the safety of bitter almond essential oil purification devices during operation, as mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a bitter almond essential oil purification device, comprising: a purification box, a water bath frame, and a distillation flask. The outer wall of the water bath frame is provided with a safety mechanism, which is used to fix the distillation flask during heating and to facilitate lifting and removal after heating is completed.

[0008] The safety mechanism includes an electric slide rail, a first friction layer, and a second friction layer. The electric slide rail is located on the outer wall of the water bath frame. A protective cover is installed at the output end of the electric slide rail. An electric telescopic rod is installed on the inner wall of the protective cover. A clamping plate is installed at the output end of the electric telescopic rod. The first friction layer is installed on the outer wall of the clamping plate. A heat insulation layer is installed on the outer wall of the distillation flask. The second friction layer is installed on the outer wall of the heat insulation layer.

[0009] Preferably, the outer wall of the purification chamber is provided with a hinged door panel, the outer wall of the purification chamber is equipped with a CNC panel, the inner wall of the purification chamber is equipped with a top heating wire, the inner wall of the purification chamber is equipped with a bottom heating wire, the inner wall of the purification chamber is equipped with a first partition, the water bath frame is located on the inner wall of the purification chamber, the inner wall of the water bath frame is equipped with a water bath heating wire, the inner wall of the water bath frame is equipped with a second partition, the distillation flask is located inside the water bath frame, the outer wall of the purification chamber is provided with a condenser tube, one end of which extends into the interior of the purification chamber, and the outer wall of the purification chamber is equipped with a vacuum pump.

[0010] Preferably, the outer wall of the purification chamber is provided with a heat dissipation mechanism, which is used to facilitate the dissipation of heat inside the purification chamber after use.

[0011] Preferably, the heat dissipation mechanism includes a frame and a filter screen, with the frame located on the outer wall of the purification chamber.

[0012] Preferably, the outer wall of the purification chamber is provided with a threaded groove, and the outer wall of the frame is equipped with a threaded rod, with one end of the threaded rod extending into the interior of the threaded groove.

[0013] Preferably, a filter screen is embedded in the inner wall of the frame, the inner wall of the filter screen is provided with a matching groove, and a sealing plug is installed on the inner wall of the matching groove.

[0014] Preferably, the outer wall of the hinge door panel is provided with a receiving groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, by installing a safety mechanism, fixes the distillation flask during heating and facilitates its lifting and removal after heating. Existing distillation flasks, after heating and purification, need to be cooled to room temperature, a process that requires manual handling of the heated flask while it is submerged in heating water, making the process cumbersome. Furthermore, the lack of any clamping device to limit the flask's position during heating can lead to displacement. This invention addresses these issues by first using an electric telescopic rod to move the clamping plates, causing the first and second friction layers to press and adhere together. The two clamping plates then fix the distillation flask in the water bath frame, preventing displacement. Once the heating and purification are complete, an electric slide rail simultaneously moves the flask above the water bath frame, removing it from the heating water. Simultaneously, the heat insulation layer effectively isolates the heat, allowing workers to easily handle the flask by holding only the heat insulation layer. The heat insulation layer has a larger area than the second friction layer.

[0017] 2. This utility model incorporates a heat dissipation mechanism to facilitate the dissipation of heat from the purification chamber after use. Existing purification chambers are commonly used in laboratories where the air is relatively pure, but small particles still exist. After use, the chamber retains a significant amount of heat, and the hinged door cannot be opened directly, as opening it would expose the chamber to outside air. Therefore, this needs improvement. Adding a filter allows the air to be filtered, enabling the hinged door to open and exchange temperature with the outside environment, thus dissipating heat from the purification chamber. The frame is moved to the outside of the purification chamber, and the threaded rod is fixed into the threaded groove. During heat dissipation, the matching groove is sealed with a sealing plug. When a distillation flask needs to be placed in the purification chamber, the sealing plug can be briefly removed from the matching groove. This allows the filter to filter the air, preventing outside air from entering and contaminating the internal structure during prolonged heat dissipation. Attached Figure Description

[0027] Please refer to Figures 1 and 2. A bitter almond essential oil purification device includes: a purification chamber 1, a water bath frame 7, and a distillation flask 10. The outer wall of the purification chamber 1 is equipped with a hinged door panel 2, a CNC panel 3, a top heating wire 4, a bottom heating wire 5, and a first partition 6. The water bath frame 7 is located on the inner wall of the purification chamber 1, and a water bath heating wire 8 and a second partition 9 are installed on its inner wall. The distillation flask 10 is located inside the water bath frame 7, and a condenser is provided on the outer wall of the purification chamber 1. 11. One end of the condenser 11 extends into the interior of the purification chamber 1. A vacuum pump 12 is installed on the outer wall of the purification chamber 1. The top heating wire 4, bottom heating wire 5, and water bath heating wire 8 are all Cr20Ni80 type. Purification is carried out inside the purification chamber 1 at a pressure of 1-5 kPa. Temperature sensors are installed in the heating areas of the top heating wire 4, bottom heating wire 5, and water bath heating wire 8, and their temperature data is fed back to the CNC panel 3. The heating area temperature of the top heating wire 4 is 40-60℃, the heating area temperature of the bottom heating wire 5 is 80-100℃, and the water bath heating wire 8 is heated by the medium water. The heating temperature needs to be 10-30℃ higher than the bottom temperature of the column to compensate for heat loss and thermal resistance. Purification is performed using a water bath method, with the distillation rate controlled at 0.5-1 drops / second to drive benzaldehyde vaporization while retaining heavy components such as benzoic acid. The condenser 11 is connected to an external receiving bottle for collecting the distilled substances. The condenser 11 is a straight pipe with an inner diameter of 10-15 mm and a length of 300-400 mm. The liquid level in the water bath frame 7 is 1-2 cm higher than the material in the distillation flask 10. The wall thickness of the distillation flask 10 is 3-5 mm, and the flask 10 is made of borosilicate glass. The stock solution to be purified is placed in distillation flask 10. Then, the purification chamber 1 is opened through hinged door 2. The distillation flask 10 is then placed in water bath frame 7, and hinged door 2 is closed. Water bath heating wire 8, bottom heating wire 5, and top heating wire 4 are activated. Then, vacuum pump 12 is activated. Using reduced pressure distillation technology, at a pressure of 1-5 kPa, by controlling the top temperature (40-60℃) and bottom temperature (80-100℃), low-boiling-point impurities and high-boiling-point heavy components in the stock solution to be purified can be removed to obtain high-purity benzaldehyde. The removed components are collected by condensation through condenser 11.

[0028] Please refer to Figures 2, 3, and 4. The outer wall of the water bath frame 7 is equipped with a safety mechanism. This mechanism secures the distillation flask 10 during heating and facilitates its removal after heating. The safety mechanism includes an electric slide rail 13, a first friction layer 17, and a second friction layer 19. The electric slide rail 13 is located on the outer wall of the water bath frame 7. A protective cover 14 is installed at the output end of the electric slide rail 13. An electric telescopic rod 15 is installed on the inner wall of the protective cover 14. A clamping plate 16 is installed at the output end of the electric telescopic rod 15. The first friction layer 17 is installed on the outer wall of the clamping plate 16. A heat insulation layer 18 is installed on the outer wall of the distillation flask 10. The second friction layer 19 is installed on the outer wall of the heat insulation layer 18. Two sets of electric slide rails 13 are provided, located on both sides of the outer wall of the water bath frame 7. The two sets of electric slide rails 13 operate synchronously based on feedback from a dual-channel encoder and synchronous trigger input / output. The dual-channel encoder is an Omron G5K synchronous controller. The electric slide rails 13 are TOPRIG S40 models. The protective cover 14 is a rectangular cover. The electric telescopic rod 15 is a HOODLANDIP 600-30mm model. The protective cover 14, clamping plate 16, and heat insulation layer 18 are all made of alumina ceramic fiber, providing excellent heat insulation. The first friction layer 17 and the second friction layer 19 are made of PEEK material. The distillation flask 10 is heavy when filled with purified liquid. With a force of 800g, the frictional force after the first friction layer 17 and the second friction layer 19 come into contact is ≥15.68N (twice the weight of the distillation flask 10). The applied positive pressure is 234.84N to 52.27N, while maintaining a frictional margin of >10% to address performance degradation during long-term use. Currently, after heating and purification, the distillation flask 10 needs to be cooled to room temperature. This process requires manual handling of the heated flask 10, which is then submerged in heating water, making handling cumbersome. Furthermore, the flask 10 lacks any clamping device for positioning during heating, potentially leading to positional shifts. Therefore, this issue needs to be addressed. The improvement involves firstly, the electric telescopic rod 15 moves the clamping plate 16, causing the first friction layer 17 and the second friction layer 19 to press and adhere together. The two sets of clamping plates 16 then fix the distillation flask 10 in the water bath frame 7, preventing the distillation flask 10 from shifting position. After the distillation flask 10 has finished heating and purifying, the electric slide rail 13 moves the distillation flask 10 to the top of the water bath frame 7, removing it from the heating water. At the same time, the heat insulation layer 18 effectively isolates the heat, allowing the operator to pick up the distillation flask 10 simply by holding the heat insulation layer 18. Furthermore, the area of ​​the heat insulation layer 18 is larger than the area of ​​the second friction layer 19.

[0029] Please refer to Figures 1 and 5. The outer wall of the purification chamber 1 is equipped with a heat dissipation mechanism to facilitate the dissipation of heat inside the purification chamber 1 after use. The heat dissipation mechanism includes a frame 20 and a filter screen 23. The frame 20 is located on the outer wall of the purification chamber 1, and the outer wall of the purification chamber 1 is provided with a threaded groove 21. A threaded rod 22 is installed on the outer wall of the frame 20, and one end of the threaded rod 22 extends into the interior of the threaded groove 21. The filter screen 23 is embedded in the inner wall of the frame 20, and the inner wall of the filter screen 23 is provided with a matching groove 24. The inner wall of the matching groove 24 is fitted with a sealing plug 25, and the outer wall of the hinge door panel 2 is provided with a receiving groove 26. The frame 20 is made of 316L stainless steel and is located outside the purification tank of the purification chamber 1, with an area larger than that of the purification tank. The threaded groove 21 is a circular threaded groove, and four sets of threaded grooves 21 are provided, with the threaded rod 22 matching the threaded groove 21. The filter screen 23 is made of 316L stainless steel fiber material with a porosity of 75-85% and an air permeability of 2800L / (m-s-kPa) (ASTM). The filter (D737) has a filtration accuracy of 0.5-5µm (capable of intercepting 99.9% of PM0.5 particles). The matching groove 24 is a rectangular groove used to place the distillation flask 10 into the purification chamber 1. The sealing plug 25 has undergone high-temperature resistant treatment. The receiving groove 26 is used to accommodate the protruding part of the sealing plug 25 when the hinge door 2 is closed. The volume of the receiving groove 26 is larger than the volume of the sealing plug 25. The existing purification chamber 1 is commonly used in laboratories where the air is relatively pure, but small particles still exist. After use, the purification chamber 1 retains a large amount of heat, and the hinge door 2 cannot be opened. Since it is in direct contact with the outside air, improvements are needed. A filter screen 23 is added to filter the air, allowing the hinged door panel 2 to open and exchange temperature with the outside, thus dissipating heat from the inside of the purification chamber 1. The frame 20 is then moved to the outside of the purification chamber 1, and the threaded rod 22 is fixed into the threaded groove 21. The matching groove 24 is sealed with a sealing plug 25 during heat dissipation. When the distillation flask 10 needs to be placed in the purification chamber 1, the sealing plug 25 can be briefly removed from the matching groove 24. This allows the filter screen 23 to filter the air, preventing outside air from entering the purification chamber 1 and causing internal contamination during prolonged heat dissipation.

[0030] Working principle: The stock solution to be purified is placed in distillation flask 10. Then, the purification chamber 1 is opened via hinged door 2, and distillation flask 10 is placed in water bath frame 7. Hinged door 2 is closed, and the water bath heating wire 8, bottom heating wire 5, and top heating wire 4 are activated. Subsequently, vacuum pump 12 operates, employing reduced pressure distillation technology. Under a pressure of 1-5 kPa, by controlling the top temperature (40-60℃) and bottom temperature (80-100℃), low-boiling-point impurities and high-boiling-point heavy components in the stock solution to be purified can be removed, yielding high-purity benzaldehyde. The removed components are collected by condensation via condenser 11. The existing distillation flask 10 is then... After heat purification, the distillation flask 10 needs to be cooled to room temperature. This process requires manual handling of the heated flask 10, which is then submerged in heating water, making the process cumbersome. Furthermore, the lack of any clamping device to limit the flask 10's position during heating could lead to displacement. To address this, the electric telescopic rod 15 moves the clamping plate 16, causing the first friction layer 17 and the second friction layer 19 to press and adhere together. The two clamping plates 16 then secure the distillation flask 10 in the water bath frame 7, preventing displacement.

Track 13 works synchronously to move the distillation flask 10 above the water bath frame 7, detaching it from the heated water. Simultaneously, the heat insulation layer 18 effectively insulates against heat, allowing operators to easily handle the flask 10 by simply holding the heat insulation layer 18. Furthermore, the area of ​​the heat insulation layer 18 is larger than that of the second friction layer 19. Existing purification chambers 1 are commonly used in laboratories where the air is relatively pure, but small particles still exist.

To improve this, a filter screen 23 is added to filter the air, allowing the hinged door 2 to open and exchange temperature with the outside, thus dissipating heat from the inside of the purification chamber 1. The frame 20 is then moved to the outside of the purification chamber 1, and the threaded rod 22 is fixed into the threaded groove 21. During heat dissipation, the matching groove 24 is sealed with a sealing plug 25. When the distillation flask 10 needs to be placed in the purification chamber 1, the sealing plug 25 can be briefly removed from the matching groove 24. This allows the filter screen 23 to filter the air, preventing outside air from entering the purification chamber 1 and causing internal contamination during prolonged heat dissipation.
