Description

Technical Field

[0001] The present invention relates to the technical field of fatty acid distillation, and particularly relates to a fatty acid refining distillation device and a distillation process. Background Art

[0002] The main purpose of distilling fatty acids is to purify them. Their raw materials are widely sourced and contain components such as impurities, fatty acids with different carbon chain lengths, etc. Distillation can remove impurities such as incompletely hydrolyzed glycerides, phospholipids, pigments, protein decomposition products, and metal ions; it can also separate fatty acids with different carbon chain lengths for different industrial uses.

[0003] In the Chinese patent with the application number CN202221641734.4, a fatty acid fine distillation device that is convenient to operate is proposed. By setting a first collection box and a second collection box, different evaporated gases can be classified for subsequent use. The main pipe and the auxiliary pipe in the storage box are bent in shape, and the heat energy released by the gas can be used to preheat the materials in the storage box, which is energy-saving and environmentally friendly.

[0004] However, during the working process of the above device, it is impossible to heat and distill at a suitable temperature according to the type of fatty acid. Since fatty acids with different carbon chain lengths require different temperatures, during the distillation process, it is necessary to first understand the type of fatty acid and then select a suitable temperature, which makes the entire working process rather troublesome and seriously affects the overall working efficiency.

[0005] Therefore, a fatty acid refining distillation device and a distillation process are proposed. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] A fatty acid refining and distillation device and distillation process proposed by the present invention. In the prior art, it is difficult for the distillation device to select a suitable distillation temperature according to different types of fatty acids. However, in the present invention, through the raw material type analysis unit, corresponding temperature setting module, primary setting module, secondary setting module, and temperature difference determination module, during the working process, the raw material type analysis unit analyzes what type of fatty acid is in the inner cylinder, and then sets different distillation temperatures according to different types of fatty acids by using the corresponding temperature setting module.

Detailed implementation manners

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] To solve the technical problem of how to select a suitable distillation temperature according to different types of fatty acids, as Figures 1 - 3 and Figure 11 shown, the following preferred technical solutions are provided:

[0040] A fatty acid refining and distillation device, comprising a main cylinder body 2, a cylinder cover 3 hinged to the upper end of the main cylinder body 2, and an inner cylinder 9 arranged inside the main cylinder body 2. A heating component 10 is arranged between the lower bottom surface of the inner cylinder 9 and the bottom of the main cylinder body 2. The upper end of the cylinder cover 3 is connected to a connection component 4. One end of the connection component 4 is provided with a condensation box 5. Inside the condensation box 5, there are a refrigeration pipe 6 and an annular pipe 7 for storing the distilled fatty acid. The lower end of the condensation box 5 is provided with a blanking cylinder 71. The blanking cylinder 71 is communicated with one end of the annular pipe 7. The other end of the annular pipe 7 is communicated with the connection component 4. One side of the blanking cylinder 71 is provided with a quality detection unit 72 for detecting the purity of the fatty acid. The quality detection unit 72 is signal-connected to a general controller outside. The upper end of the cylinder cover 3 is provided with a rubber sleeve 8. An insertion rod is movably inserted inside the rubber sleeve 8. One end of the insertion rod is provided with a raw material type analysis unit 81. The raw material type analysis unit 81 is located inside the inner cylinder 9. The raw material type analysis unit 81 is signal-connected to the general controller. The lower end of the main cylinder body 2 is provided with a first support frame 1. The lower end of the condensation box 5 is provided with a second support frame 52. The upper end of the condensation box 5 is provided with a fan group 51. The air outlet of the fan group 51 is communicated with the inside of the condensation box 5. Add the fatty acid to be distilled into the inner cylinder 9, turn on the heating component 10 to make the heating component 10 generate heat. The generated heat will heat the fatty acid in the inner cylinder 9. The fatty acid is heated and vaporized. The generated gas enters the annular pipe 7 along the connection component 4. Then connect the refrigeration pipe 6 to an external refrigerator. The cold air generated by the refrigerator enters the refrigeration pipe 6, so as to cool the vaporized fatty acid in the annular pipe 7 and make it become liquid fatty acid. Finally, collect it by using the blanking cylinder 71.

[0041] Inside the general controller, there is a corresponding temperature setting module. The corresponding temperature setting module is signal-connected to a cooling control module. Inside the corresponding temperature setting module, there are signal-connected a first-level setting module, a second-level setting module and a temperature difference determination module. The corresponding temperature setting module is signal-connected to both the quality detection unit 72 and the raw material type analysis unit 81. On the outer surface of the main cylinder body 2, there are a first temperature controller 26 and a second temperature controller 27. One end of the first temperature controller 26 is located inside the inner cylinder 9. One end of the second temperature controller 27 is located between the lower bottom surface of the inner cylinder 9 and the bottom of the main cylinder body 2. The first temperature controller 26 is signal-connected to the first-level setting module. The second temperature controller 27 is signal-connected to the second-level setting module.

[0042] An electric push rod 21 is rotatably arranged on the outer surface of the main cylinder body 2. A first connecting piece 22 is arranged at the upper end of the main cylinder body 2. A second connecting piece 23 is rotatably arranged on one side of the first connecting piece 22. A main motor 24 is arranged at the upper end of the second connecting piece 23. The output end of the main motor 24 is provided with a transmission belt 25. One end of the electric push rod 21 is rotatably connected to the second connecting piece 23. An installation seat is arranged on the upper surface of the cylinder cover 3. A transmission rod 251 penetrates through the installation seat. One end of the transmission belt 25 is connected to the transmission rod 251. One end of the second connecting piece 23 is connected to the installation seat. By the telescopic movement of the electric push rod 21, the second connecting piece 23 can be rotated relative to the first connecting piece 22, and the second connecting piece 23 will drive the installation seat and the cylinder cover 3 to tilt upwards, thereby realizing the opening and closing of the cylinder cover 3. Through the main motor 24, its output end drives the transmission belt 25 to rotate, and then drives the transmission rod 251 to rotate. A stirring head 252 is arranged on the outer surface of one end of the transmission rod 251, and the stirring head 252 is located inside the inner cylinder 9.

[0043] The connection component 4 includes an angle iron arranged on the outer surface of the first connecting piece 22, a pre-storage cylinder 41 arranged at the upper end of the angle iron, and hoses 42 arranged at both ends of the pre-storage cylinder 41. The pre-storage cylinder 41 is communicated with the annular pipe 7 through one group of the hoses 42, and the other group of the hoses 42 is communicated with the cylinder cover 3. The heated fatty acid will vaporize, and the vaporized fatty acid enters the annular pipe 7 through the hoses 42 and the pre-storage cylinder 41, and then is cooled.

[0044] An inlet pipe 31 and an air extraction pipe 32 are arranged on the upper surface of the cylinder cover 3. The inlet pipe 31 is communicated with the fatty acid to be distilled outside. The air extraction pipe 32 is communicated with an external air extraction pump. The fatty acid to be distilled is added into the inner cylinder 9 through the inlet pipe 31. During the distillation process, the air in the inner cylinder 9 can be pumped out by the air extraction pump, making the whole distillation process in a vacuum state.

[0045] Specifically, during the working process, the raw material type analysis unit 81 analyzes the type of fatty acid in the inner cylinder 9, and then sets different distillation temperatures according to different types of fatty acids using the corresponding temperature setting module. Among them, the first-level setting module is used to control the first temperature controller 26, and the second-level setting module is used to control the second temperature controller 27. The first temperature controller 26 can detect the temperature value of the fatty acid in the inner cylinder 9, and the second temperature controller 27 can detect the temperature value of the heating component 10 near the bottom surface of the inner cylinder 9 and the bottom of the main cylinder 2. After the distillation is completed, the cooling control module is used to turn on the external refrigerator connected to the refrigeration pipe 6 to cool and liquefy the vaporized fatty acid. The liquefied fatty acid will enter the blanking cylinder 71, and the quality detection unit 72 is used to detect the purity of the fatty acid after distillation. If the purity does not meet the standard, it means that there is a problem with the distillation temperature, and then the temperature of the heating component 10 needs to be set again through the corresponding temperature setting module, and the temperature difference determination module is used for determination. When the temperature difference detected by the first temperature controller 26 and the second temperature controller 27 is large, it means that coking occurs at the bottom of the inner cylinder 9, resulting in the heat generated by the heating component 10 not being transferred to the inside of the inner cylinder 9.

[0046] To solve the technical problem of how to prevent coking, as Figures 4 - 10 shown, the following preferred technical solutions are provided:

[0047] Inside the inner cylinder 9, a scraping component 28 is provided. The scraping component 28 includes a connection disk 281 provided at one end of the transmission rod 251, a lower connection block 282 provided at the lower end of the connection disk 281. Chutes are provided on both sides of the lower connection block 282. Positioning blocks 283 are fixed in the chutes. A displacement block 285 is also movably arranged in the chutes. A spring 284 is provided on one side of the positioning block 283. One end of the spring 284 is connected to the displacement block 285. An L-shaped plate 286 is provided on the outer surface of the displacement block 285. A pneumatic telescopic rod is provided on one side of the displacement block 285. One end of the pneumatic telescopic rod is connected to the displacement block 285. A first-stage sleeve 2861 is provided on one side of the L-shaped plate 286. A second-stage sleeve 2862 is elastically connected inside the first-stage sleeve 2861. A third-stage sleeve 2863 is elastically connected inside the second-stage sleeve 2862. External connection blocks 2864 are provided on one side of the first-stage sleeve 2861, the second-stage sleeve 2862, and the third-stage sleeve 2863. Scrapers 2865 are provided at the lower ends of the external connection blocks 2864. The three groups of scrapers 2865 are arranged on the same straight line, and cavities are provided in the three groups of scrapers 2865. When the transmission rod 251 starts to rotate, it will drive the lower connection block 282 to rotate, and then drive the first-stage sleeve 2861, the second-stage sleeve 2862, and the third-stage sleeve 2863 to rotate. Since the lower connection block 282 is not corresponding to the center of the inner cylinder 9, and one end of the third-stage sleeve 2863 is in contact with the inner wall of the inner cylinder 9, with continuous rotation, the third-stage sleeve 2863 will be compressed into the second-stage sleeve 2862, and the second-stage sleeve 2862 will be compressed into the first-stage sleeve 2861. The three groups of scrapers 2865 will also be compressed together. While rotating, the scrapers 2865 will scrape the slag formed at the bottom of the inner cylinder 9. An arc plate 2866 is embedded on the upper surface of the third-stage sleeve 2863. An installation plate 2867 is also provided on the upper surface of the third-stage sleeve 2863. A roller 2868 is movably arranged at the lower end of the installation plate 2867. During the rotation process, the outer surface of the roller 2868 closely adheres to the inner wall of the inner cylinder 9. During the rotation process, as the first-stage sleeve 2861, the second-stage sleeve 2862, and the third-stage sleeve 2863 are continuously compressed, the arc plate 2866 will gradually pull the scraped residues to the vicinity of the middle position at the bottom of the inner cylinder 9.

[0048] Inside the lower connecting block 282, there is an inner plate 2821. A reciprocating spiral groove 2822 is formed on the inner wall of the lower connecting block 282. The inner plate 2821 is movably connected to the reciprocating spiral groove 2822. A through rod 2823 is provided at the lower end of the inner plate 2821. An air cushion 2825 is arranged between the inner plate 2821 and the inner wall of the lower connecting block 282. The air cushion 2825 is communicated with the pneumatic telescopic rod through a trachea. A magnetic column 2824 is provided at the lower end of the through rod 2823. One end of the magnetic column 2824 penetrates through the lower bottom surface of the inner cylinder 9. As the lower connecting block 282 rotates, the inner plate 2821 moves up and down along the reciprocating spiral groove 2822, which causes the inner plate 2821 to squeeze the air cushion 2825, so that the gas in the air cushion 2825 is squeezed into the pneumatic telescopic rod, causing the pneumatic telescopic rod to extend, thus achieving the effect of reciprocatingly lifting the L-shaped plate 286 and preventing the scraper 2865 from continuously scraping the bottom of the inner cylinder 9.

[0049] The heating component 10 includes a vertical plate 101 arranged at the bottom of the main cylinder body 2, an electric heating rod 102 penetrating through the outer surface of the vertical plate 101. A conductive head 103 is provided at one end of the electric heating rod 102. A sleeve wheel 104 is rotatably arranged on one side of the vertical plate 101. An extension rod 105 is provided at one end of the sleeve wheel 104. Blades 106 are arranged on the outer surface of the extension rod 105. There are two groups of the sleeve wheel 104 and the extension rod 105. A transmission steel belt is sleeved between the two groups of sleeve wheels 104. A positioning column 107 is also provided at the bottom of the main cylinder body 2. A connecting seat 108 is provided at one end of one group of the extension rods 105. The connecting seat 108 is fixedly connected to the positioning column 107. A torsion spring is arranged inside the connecting seat 108. One end of the torsion spring is connected to the extension rod 105, and the other end of the torsion spring is connected to the inner wall of the connecting seat 108. A magnetic plate 109 is arranged on the outer surface of one group of the extension rods 105. The magnetic plate 109 corresponds to the position of the magnetic column 2824, and the magnetic plate 109 and the magnetic column 2824 are magnetically repulsive. When the power is turned on, the electric heating rod 102 generates heat to heat the fatty acid inside the inner cylinder 9. As the through rod 2823 continuously moves up and down reciprocally, an intermittent repulsive phenomenon will occur between the magnetic column 2824 and the magnetic plate 109, causing the magnetic plate 109 to drive the extension rod 105 to rotate, so that the blades 106 swing to generate an air flow, thereby expanding the heat generation range of the electric heating rod 102.

[0050] A discharge component 11 is provided at the lower end of the main cylinder body 2. The discharge component 11 includes a butt joint pipe 111 communicated with the lower bottom surface of the inner cylinder 9, a straight-through pipe 112 movably arranged at the lower end of the butt joint pipe 111, and a collection cylinder 113 communicated with the lower end of the main cylinder body 2. The collection cylinder 113 is movably sleeved on the outer surface of the straight-through pipe 112. A discharge groove 117 is formed on the outer surface of the straight-through pipe 112. The discharge groove 117 is located above the collection cylinder 113. A fastener 114 is further arranged on the outer surface of the straight-through pipe 112. The fastener 114 is located below the collection cylinder 113. A machine box 115 is arranged at the lower end of the straight-through pipe 112. A rocker 116 is arranged on one side of the machine box 115. A bevel gear set is arranged inside the machine box 115. The rocker 116 is connected with the straight-through pipe 112 through the bevel gear set. The bevel gear set is composed of two bevel gears. One of the bevel gears is connected with the rocker 116, and the other bevel gear is connected with the straight-through pipe 112. The two bevel gears are meshed with each other. The residues generated during the operation of the inner cylinder 9 will enter the straight-through pipe 112 through the butt joint pipe 111 and be discharged from the discharge groove 117 into the collection cylinder 113. A valve pipe is arranged on one side of the collection cylinder 113. When it is necessary to discharge the residues in the collection cylinder 113, an external air pump can be connected to the collection cylinder 113 through the valve pipe.

[0051] A control valve is arranged inside the butt joint pipe 111. An inclined rod 118 is arranged at the pipe orifice of the straight-through pipe 112. By rotating the rocker 116, the straight-through pipe 112 rotates, and the straight-through pipe 112 drives the inclined rod 118 to rotate, preventing the residues from blocking at the junction of the butt joint pipe 111 and the straight-through pipe 112.

[0052] The present invention also provides another technical solution, a fatty acid refining and distillation process, including the following steps:

[0053] S1: Inject the fatty acid to be distilled into the inner cylinder 9, and then turn on the electric heating rod 102 to distill the fatty acid. During the distillation process, start the main motor 24 to make the transmission rod 251 and the stirring head 252 rotate to stir the fatty acid;

[0054] S2: During the rotation of the transmission rod 251, the scraper 2865 rotates accordingly. The rotating scraper 2865 scrapes the residues at the bottom of the inner cylinder 9 to prevent the residues from bottoming out;

[0055] S3: During the distillation process, the liquid fatty acid will vaporize and enter the annular pipe 7. At the same time, connect the refrigeration pipe 6 with an external refrigerator, and the cold air generated by the refrigerator enters the refrigeration pipe 6, so as to cool the vaporized fatty acid in the annular pipe 7 to make it become liquid fatty acid, completing the distillation. Thus, all the distillation processes are completed.

[0056] Specifically, when the transmission rod 251 starts to rotate, it will drive the lower connecting block 282 to rotate, and then drive the first-stage sleeve 2861, the second-stage sleeve 2862, and the third-stage sleeve 2863 to rotate. Since the center of the lower connecting block 282 does not correspond to the center of the inner cylinder 9, and one end of the third-stage sleeve 2863 is in contact with the inner wall of the inner cylinder 9, with continuous rotation, the third-stage sleeve 2863 will be compressed into the second-stage sleeve 2862, and the second-stage sleeve 2862 will be compressed into the first-stage sleeve 2861. The three groups of scraping plates 2865 will also be compressed together. While rotating, the scraping plates 2865 will scrape the slag formed at the bottom of the inner cylinder 9. During the rotation, the outer surface of the roller 2868 closely adheres to the inner wall of the inner cylinder 9. During the rotation, as the first-stage sleeve 2861, the second-stage sleeve 2862, and the third-stage sleeve 2863 are continuously compressed, the arc plate 2866 will gradually pull the scraped residues to the vicinity of the middle position at the bottom of the inner cylinder 9, facilitating the discharge of the residues.

[0057] As described above, the above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
