Description

Technical Field

[0001] The utility model relates to the technical field of flavor and fragrance processing, and more specifically to a rectification kettle for producing and processing coumarin crude products. Background Art

[0002] Coumarin is a natural organic compound that is commonly used in food, spices, cosmetics, and medicine. Existing processed coumarin is mostly mixed with solvents. In order to obtain coumarin with higher purity, further purification is required. At this stage, the distillation kettle can be used to separate the mixture of coumarin and other impurities. By adjusting the operating conditions such as temperature and pressure, the coumarin is evaporated and condensed for collection, thereby achieving separation from other components.

[0003] China Patent Authorization Announcement No.: CN206232680U provides a distillation kettle for the production and processing of coumarin crude products. The scheme adopts auxiliary and main heating bodies to heat the distillation liquid in turn, which can improve the heating efficiency and heating uniformity, and improve the product quality. The distillation kettle adopts a hollow ring structure, and combined with a liquid pump, the distillation liquid can circulate inside the distillation kettle to avoid side reactions of the distillation liquid at high temperatures. A wastewater separation and discharge device is used to separate and discharge the wastewater generated in the distillation process in time to protect the distillation environment.

[0004] However, in the process of using a distillation kettle to distill and separate the mixture of coumarin and solvent, coumarin will enter the condenser together with the steam, and be cooled into liquid in the condenser, and finally be collected by a collection tank. In this process, a large amount of steam-like coumarin will adhere to the inside of the condenser for cooling, and they will fall off from the inner wall only after forming larger water droplets. When a large number of water droplets accumulate on the inner wall of the condenser, these water droplets will form a thin film or drip on the wall of the tube, hindering the transfer of heat during the condensation process, which will lead to a decrease in condensation efficiency and make it impossible for the steam to be fully condensed, thereby affecting the effect of distillation or other related processes. Therefore, in view of the above problems, a distillation kettle for the production and processing of crude coumarin is proposed. Utility Model Content

[0032] Example:

[0033] See also Figure 1 A distillation kettle for producing and processing crude coumarin comprises a distillation kettle 1, one end of the distillation kettle 1 is fixedly connected with a steam pipe 2 connected with the inner cavity of the distillation kettle 1, the end of the steam pipe 2 away from the distillation kettle 1 is fixedly connected with a condenser 3 connected with the steam pipe 2, the end of the condenser 3 away from the steam pipe 2 is fixedly connected with a collecting tank 4 connected with the condenser 3, a driving component 5 is arranged on the upper side of the condenser 3, and a scraping component 6 is arranged in the inner cavity of the condenser 3.

[0034] Coumarin is usually extracted from natural plant materials. During the extraction process, the plant materials are usually mixed with a solvent, and the coumarin is dissolved in the solvent by heating and stirring. The extracted solution containing coumarin usually also contains other impurities. In order to obtain coumarin with higher purity, further purification treatment is required. At this stage, the distillation kettle can be used to separate the mixture of coumarin and other impurities. By adjusting the operating conditions such as temperature and pressure, the coumarin is evaporated and condensed and collected, thereby achieving separation from other components. In this scheme, the user can pour the coumarin solution into the interior of the distillation kettle 1. The distillation kettle 1 is equipped with a heating device and a stirring device. The coumarin solution can be stirred and heated to make the solution boil. The coumarin in the solution will evaporate, and the evaporated water vapor will follow the steam pipe 2 to the interior of the condenser 3. The interior of the condenser 3 is equipped with a cooling device, which can quickly cool and liquefy the water vapor entering the condenser 3, turning it into small water droplets attached to the inner wall of the condenser 3, and finally falling off the inner wall and flowing into the collection tank 4. The liquid flowing into the collection tank 4 is the purified coumarin.

[0035] See also Figure 2The driving assembly 5 includes a pair of mounting plates 501, and the pair of mounting plates 501 are fixedly connected to the condenser 3. A servo motor 502 is fixedly connected to the inner end of one of the mounting plates 501, and a reciprocating screw rod 503 is fixedly connected to the output end of the servo motor 502. The reciprocating screw rod 503 is rotatably connected to the other mounting plate 501 at one end away from the servo motor 502. The outer surrounding sleeve of the reciprocating screw rod 503 is provided with a screw sleeve 507, and the outer end of the screw sleeve 507 is fixedly connected to an iron ring 508, and the iron ring 508 is sleeved on the outer side of the condenser 3. A limit rod 504 is fixedly connected between the pair of mounting plates 501, and a movable block 505 is slidably connected to the limit rod 504. An electromagnet 506 is installed on the upper end of the movable block 505, and the movable block 505 is fixedly connected to the screw sleeve 507.

[0036] After the water vapor enters the condenser 3, it will quickly cool and liquefy and turn into small water droplets attached to the inner wall of the condenser 3. When a large number of water droplets accumulate on the inner wall of the condenser, these water droplets will form a thin film or drip on the tube wall, hindering the heat transfer during the condensation process, which will lead to a decrease in the condensation efficiency and make it impossible for the steam to be fully condensed, thereby affecting the effect of distillation or other related processes. Therefore, the device is provided with a driving component 5 and a scraping component 6 to realize reciprocating scraping of the inner wall of the condenser 3, so as to make the water droplets on the inner wall of the condenser 3 fall off in time to avoid accumulation.

[0037] The user can start the servo motor 502 to drive the reciprocating screw 503 to rotate between a pair of mounting plates 501. The rotation of the reciprocating screw 503 drives the screw sleeve 507 to reciprocate at the outer end of the reciprocating screw 503, and then the screw sleeve 507 can drive the iron ring 508 to move at the outer end of the condenser 3, and drive the movable block 505 to slide on the limit rod 504. The outer end of the iron ring 508 is wrapped with a coil, and the coil is connected to the electromagnet 506. During the movement of the screw sleeve 507, the electromagnet 506 is started, and the electromagnet 506 passes current through the coil, which can make the iron ring 508 magnetic.

[0038] See also Figure 3 The scraping component 6 includes an annular magnetic block 601, and a plurality of balls 602 arranged equidistantly in a ring are installed at the outer end of the annular magnetic block 601, and the balls 602 abut against the inner wall of the condenser 3. A pair of rubber strips 603 are installed around the annular magnetic block 601, and the rubber strips 603 abut against the inner wall of the condenser 3.

[0039] In this solution, the scraping component 6 is located inside the condenser 3, and the position of the scraping component 6 corresponds to the iron ring 508. Through the movement of the iron ring 508, the magnetic iron ring 508 will attract the annular magnetic block 601, thereby driving the annular magnetic block 601 to follow the iron ring 508 to move in the inner cavity of the condenser 3. During the movement of the annular magnetic block 601, multiple balls 602 roll on the inner wall of the condenser 3, ensuring the stability of the movement of the annular magnetic block 601. At the same time, the annular magnetic block 601 will drive a pair of rubber strips 603 to repeatedly scrape the inner wall of the condenser 3, so that the water droplets gathered on the inner wall of the condenser 3 fall off quickly, thereby avoiding the film formed by the water droplets hindering the heat transfer during the condensation process.

[0040] Working principle:

[0041] During use, the user can pour the coumarin solution into the interior of the distillation kettle 1. The distillation kettle 1 is equipped with a heating device and a stirring device, which can stir and heat the coumarin solution to make the solution boil, and the coumarin in the solution will evaporate. The evaporated water vapor will follow the steam pipe 2 to the interior of the condenser 3. The condenser 3 is equipped with a cooling device, which can quickly cool and liquefy the water vapor entering the condenser 3, turning it into small water droplets attached to the inner wall of the condenser 3. At this time, the user can start the servo motor 502 to drive the reciprocating screw 503 to rotate, and the reciprocating screw 503 drives the screw sleeve 507 to reciprocate at the outer end of the reciprocating screw 503, and then the screw sleeve 507 can drive the iron ring 508 to move at the outer end of the condenser 3, and drive the movable block 505 to slide on the limit rod 504, and the iron ring A coil is wound around the outer end of 508, and the coil is connected to the electromagnet 506. During the movement of the screw sleeve 507, the electromagnet 506 is started, and the electromagnet 506 passes current through the coil, which can make the iron ring 508 magnetic. The magnetic iron ring 508 will attract the annular magnetic block 601, thereby driving the annular magnetic block 601 to move in the inner cavity of the condenser 3 following the iron ring 508. During the movement of the annular magnetic block 601, multiple balls 602 roll on the inner wall of the condenser 3 to ensure the stability of the movement of the annular magnetic block 601. At the same time, the annular magnetic block 601 will drive a pair of rubber strips 603 to repeatedly scrape the inner wall of the condenser 3, so that the water droplets gathered on the inner wall of the condenser 3 will fall off quickly, and finally flow into the collection tank 4 with the push of the rubber strips 603 to be collected to form pure coumarin.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
