Description

Technical Field

[0001] The invention relates to the technical field of fatty acid extraction, and in particular to a temperature-controlled circulating fatty acid extraction device. Background Art

[0002] Fatty acids are mainly used to manufacture daily cosmetics, detergents, industrial fatty acid salts, coatings, paints, rubber, soaps, etc. Fatty acids are present in large quantities in soybeans, peanuts, corn and other plant fruits. In the process of extracting fatty acids from soybeans, peanuts, corn and other plant fruits, the raw materials are first crushed and then placed in the filter paper tube in the Soxhlet extractor. The solvent in the flask in the Soxhlet extractor is then heated to boil the solvent and generate steam. The solvent vapor enters the condenser and condenses into liquid, which flows back into the filter paper tube to extract the raw materials, so that the fatty acids in the raw materials are dissolved in the solvent. The dissolved fatty acids flow back into the beaker under the influence of the solvent. This process is cyclically repeated and the fatty acids can be extracted smoothly from the raw materials.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] When the temperature-controlled circulating fatty acid extraction device is used, in order to thoroughly extract fatty acids from soybeans, peanuts, corn and other plant fruits, the raw materials are usually crushed first, and then placed in the filter paper tube in the Soxhlet extractor. The solvent in the flask in the Soxhlet extractor is then heated to make the solvent boil and generate steam. The solvent vapor enters the condenser and condenses into liquid, which flows back into the filter paper tube to extract the raw materials, so that the fatty acids in the raw materials are dissolved in the solvent. The dissolved fatty acids flow back to the beaker under the influence of the solvent. This process can be circulated continuously to smoothly extract fatty acids from the raw materials. However, since the gaps between the raw materials are very small, it takes a long time for the condensed solution to pass through the raw materials, so that the extraction process usually takes more than ten hours, and the extraction efficiency is not high.

[0040] To this end, an embodiment of the present invention provides a temperature-controlled circulating fatty acid extraction device, the purpose of which is at least to set a booster component 5 at the steam pipe 32, so that the booster component 5 can increase the pressure inside the extraction tube 3, so that the condensed solution can pass through the gaps between the raw materials more quickly and flow back to the extraction bottle 2, thereby completing the extraction of fatty acids more efficiently.

[0041] Embodiment: A temperature-controlled circulating fatty acid extraction device, such as Figure 1 - Figure 4 As shown, it includes a mounting frame 1, and a heating barrel 11 is fixedly mounted at the bottom;

[0042] The extraction bottle 2 is located inside the heating barrel 11 and is used to contain the solvent;

[0043] The extraction tube 3 is located above the extraction bottle 2 and is used to hold the raw material. A reflux pipe 31 and a steam pipe 32 are respectively connected on both sides.

[0044] The condenser 4 is used to condense the steam flowing out of the steam pipe 32, and is installed on the side of the mounting frame 1 in a lifting manner, and is located above the extraction tube 3 and communicated with the inside of the extraction tube 3;

[0045] The booster assembly 5 is used to boost the pressure inside the extraction tube 3 so that the condensed solvent can quickly contact the raw material and reflux the condensed solvent from the reflux pipe 31 into the extraction bottle 2 , and is connected and installed on the steam pipe 32 .

[0046] In the present invention, by arranging a booster assembly 5 at the steam pipe 32, the end of the steam pipe 32 connected to the extraction tube 3 can be pressurized, and the pressure inside the extraction tube 3 can be increased, so that the condensed solution can pass through the gaps between the raw materials more quickly and flow back to the extraction bottle 2, thereby completing the extraction of fatty acids more efficiently and improving the efficiency of extracting fatty acids in the raw materials through the solution.

[0047] Furthermore, if Figure 2As shown, a lifting member 12 is fixedly installed on the upper end of the mounting frame 1. The lifting member 12 is used to drive the condenser 4 to rise and fall, and includes a threaded rod 121 and a first driving member 122. The first driving member 122 is used to drive the threaded rod 121 to rotate. A fixing frame 41 is fixedly installed on the side of the condenser 4. The fixing frame 41 is threadedly connected to the threaded rod 121. The threaded rod 121 drives the fixing frame 41 and the condenser 4 on the fixing frame 41 to move up and down.

[0048] Among them, by arranging the first driving member 122 and the threaded rod 121 on the mounting frame 1, when it is necessary to add raw materials into the extraction tube 3, the threaded rod 121 can be driven to rotate by the first driving member 122. During the rotation of the threaded rod 121, the threaded rod 121 cooperates with the thread of the fixing frame 41, so that the fixing frame 41 drives the condensing tube 4 to move upward as a whole, so that the lower part of the condensing tube 4 can be moved away from the extraction tube 3, and the upper opening of the extraction tube 3 is opened, so that the raw materials extracted from the extraction tube 3 can be taken out more conveniently and new raw materials can be added.

[0049] It should be noted that the first driving member 122 may be a servo motor.

[0050] Furthermore, if Figure 4 As shown, the heating barrel 11 is fixedly mounted on the bottom of the mounting frame 1 , and a spoiler assembly 6 is rotatably mounted inside the heating barrel 11 , and the spoiler assembly 6 is used to spoil the heating liquid inside the heating barrel 11 .

[0051] Among them, by arranging the spoiler component 6 inside the heating barrel 11, the heating medium inside the heating barrel 11 can flow during the heating process, which can increase the heat exchange efficiency between the heating medium and the outer wall of the extraction bottle 2, and can heat the solution inside the extraction bottle 2 more quickly.

[0052] Furthermore, if Figure 4 , Figure 5 As shown, the spoiler assembly 6 includes a rotating shaft 61 rotatably mounted on the bottom of the mounting frame 1, the upper end of the rotating shaft 61 extends into the interior of the heating barrel 11, and the upper end of the rotating shaft 61 is provided with a plurality of arc plates 63 that fit the outer wall contour of the extraction bottle 2, and each of the arc plates 63 is provided with a plurality of groups of spoiler plates 64 on the end face facing the outer wall of the extraction bottle 2, and a second driving member 62 is fixedly installed on the bottom of the mounting frame 1, and the second driving member 62 is transmission-connected to the rotating shaft 61.

[0053] Among them, by arranging an arc plate 63 on the outer side of the heating barrel 11, as the arc plate 63 rotates, the heating medium (an oil bath can be selected) inside the heating barrel 11 can be driven to flow relative to each other, and by arranging a spoiler 64 obliquely on the inner side of the arc plate 63, during the rotation of the arc plate 63, the spoiler 64 drives the heating medium to flow upward or downward, thereby increasing the heat exchange efficiency between the heating medium and the outer wall of the extraction bottle 2.

[0054] Furthermore, if Figure 5 , Figure 6 As shown, the booster assembly 5 includes a mounting cylinder 51 sealed at both ends, a sliding piston 52 is coaxially slidably mounted inside the mounting cylinder 51, a connecting through hole 5201 is provided on the sliding piston 52, the connecting through hole 5201 is closed when the sliding piston 52 moves upward, and is opened when the sliding piston 52 moves downward, a sliding rod 54 is fixedly mounted below the sliding piston 52, and a driving assembly for driving the sliding rod 54 to move up and down is provided below the sliding rod 54.

[0055] Among them, by arranging a sliding piston 52 inside the installation cylinder 51, the interior of the installation cylinder 51 is divided into a pressurized space and a negative pressure space. When the sliding piston 52 moves upward driven by the sliding rod 54, the sliding piston 52 squeezes the gas inside the installation cylinder 51, so that the air pressure inside the steam pipe 32 connected to the top of the installation cylinder 51 increases, and the air pressure inside the extraction tube 3 connected to the upper end of the steam pipe 32 increases, so that the condensed solution quickly passes through the gap between the raw materials. In addition, when the sliding piston 52 moves upward, a negative pressure is generated in the space below the sliding piston 52, and a negative pressure is generated inside the extraction bottle 2 connected to the bottom of the steam pipe 32, so that the solution inside the extraction bottle 2 is easier to evaporate (the air pressure decreases, and the evaporation temperature of the liquid also decreases), which can make the evaporation efficiency of the solution higher.

[0056] In addition, a guide shaft 53 is coaxially fixedly installed inside the installation cylinder 51 . The guide shaft 53 passes through the sliding piston 52 and is slidingly and sealingly connected to the sliding piston 52 .

[0057] Furthermore, if Figure 6 , Figure 7 As shown, the driving assembly includes a linkage sleeve 55 fixedly installed under the sliding rod 54, a connecting column 551 is fixedly installed on the inner wall of the linkage sleeve 55, a guide column 66 is coaxially arranged inside the linkage sleeve 55, and a guide groove 6601 is circumferentially arranged on the outer wall of the guide column 66, the connecting column 551 is inside the guide groove 6601, and during the rotation of the guide column 66, the guide groove 6601 is used to guide the guide column 66 to move up and down.

[0058] The linkage sleeve 55 is arranged below the sliding rod 54, and the guide post 66 is rotatably installed inside the linkage sleeve 55. During the rotation of the guide post 66, the guide post 66 on the inner wall of the linkage sleeve 55 is driven to slide inside the guide groove 6601 (the specific shape of the guide groove 6601 is as shown in FIG. Figure 6 As shown in FIG. 5 , the linkage sleeve 55 drives the sliding rod 54 to move up and down, thereby achieving the purpose of driving the sliding piston 52 to move up and down.

[0059] Furthermore, if Figure 6 , Figure 7 As shown, a linkage shaft 65 is rotatably mounted on the mounting frame 1 , and the linkage shaft 65 is located below the guide column 66 and fixedly connected to the guide column 66 . The linkage shaft 65 is transmission-connected to the rotating shaft 61 through a transmission member 67 at its bottom.

[0060] Furthermore, if Figure 7 As shown, a sealing groove 5202 is provided on the lower end surface of the sliding piston 52, and a closing disk 56 is slidably installed inside the sealing groove 5202. The closing disk 56 is used to close the connecting hole 5201 during the upward movement of the sliding piston 52. The sliding rod 54 is fixedly installed on the bottom of the closing disk 56, and a plurality of limiting columns 561 are fixedly installed on the closing disk 56. The plurality of limiting columns 561 are distributed on the closing disk 56 at circumferential intervals. The upper ends of the limiting columns 561 pass through the sliding piston 52, and the limiting columns 561 are slidably connected to the sliding piston 52. A limiting block for limiting the sliding position of the limiting column 561 is provided on the top of the limiting column 561; the connecting hole 5201 is arranged at the position where the sealing groove 5202 is located.

[0061] Among them, by arranging a closing disk 56 under the sliding piston 52, during the upward movement of the sliding rod 54, the closing disk 56 will be pushed against the inside of the sealing groove 5202 under the sliding piston 52, so that the closing disk 56 blocks the connecting hole 5201, so that the sliding piston 52 completely blocks the upward and downward flow of gas. During the downward movement of the sliding rod 54, due to the friction between the sliding piston 52 and the inner wall of the mounting cylinder 51, the sliding piston 52 does not move downward in the initial stage (at this time, the connecting hole 5201 is opened, and the solution vapor can enter from the connecting hole 5201 to the top of the sliding piston 52, and then enter the inside of the condenser 4). When the sliding rod 54 drives the closing disk 56 to move downward to a certain distance, the connecting column 551 on the closing disk 56 will press against the upper wall of the sliding piston 52, and then the sliding rod 54 will drive the sliding piston 52 to move downward;

[0062] It should be noted that both the turbulence work inside the heating barrel 11 and the up and down movement of the sliding piston 52 inside the booster assembly 5 are relatively slow movements, and no additional speed-changing parts are required for adjustment during use.

[0063] Furthermore, if Figure 4 As shown, a connecting frame is provided on the outer side of the installation tube 51 , and the connecting frame is fixedly mounted on the installation frame 1 , and the connecting frame is used to limit the position of the installation tube 51 .

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
