Description

Technical Field

[0001] The invention relates to the technical field of fatty acid distillation, and in particular to fatty acid refining distillation equipment and a distillation process. Background Art

[0002] Fatty acids need to be distilled mainly for purification. The raw materials are widely available and contain impurities, fatty acids of different carbon chain lengths and other components. Distillation can remove impurities such as incompletely hydrolyzed glycerides, phospholipids, pigments, protein decomposition products and metal ions; it can also separate fatty acids of different carbon chain lengths for different industrial uses.

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

[0004] However, during operation, the above-mentioned device is unable to perform heating and distillation at an appropriate temperature according to the type of fatty acid.

The feed pipe 31 is connected to the external fatty acid to be distilled, and the exhaust pipe 32 is connected to the external exhaust pump.

A spring 284 is arranged on one side of the positioning block 283, and one end of the spring 284 is connected to the displacement block 285. An L-shaped plate 286 is arranged on the outer surface of the displacement block 285, and a pneumatic telescopic rod is arranged on one side of the displacement block 285. One end of the compression and telescopic rod is connected to the displacement block 285, and a primary sleeve 2861 is provided on one side of the L-shaped plate 286, and a secondary sleeve 2862 is elastically connected to the internal part of the primary sleeve 2861, and a tertiary sleeve 2863 is elastically connected to the internal part of the secondary sleeve 2862.

Since the lower connecting block 282 does not correspond to the center of the inner cylinder 9, and one end of the tertiary sleeve 2863 is in contact with the inner wall of the inner cylinder 9, with continuous rotation, the tertiary sleeve 2863 will be compressed into the secondary sleeve 2862, and the secondary sleeve 2862 will be compressed into the primary sleeve 2861. The three groups of scrapers 2865 will also be compressed together, and while rotating The scraper 2865 will scrape off the slag at the bottom of the inner tube 9.

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 penetrating rod 2823 continuously moves back and forth up and down, the magnetic column 2824 and the magnetic plate 109 will intermittently repel each other, so that the magnetic plate 109 drives the extension rod 105 to rotate, so that the blade 106 swings, generates airflow, and expands the heat generation range of the electric heating rod 102.

[0030] The lower end of the main cylinder 2 is provided with a discharge component 11, which includes a butt-joint pipe 111 connected to the lower bottom surface of the inner cylinder 9, a straight pipe 112 movably arranged at the lower end of the butt-joint pipe 111, and a collecting cylinder 113 connected to the lower end of the main cylinder 2.

A valve pipe is arranged on one side of the collecting cylinder 113. When the residue in the collecting cylinder 113 needs to be discharged, the collecting cylinder 113 can be connected to an external air pump through the valve pipe.

[0031] A control valve is provided inside the butt-joint pipe 111, and an inclined rod 118 is provided at the mouth of the straight pipe 112. By rotating the rocker 116, the straight pipe 112 rotates, and the straight pipe 112 drives the inclined rod 118 to rotate, thereby preventing the junction of the butt-joint pipe 111 and the straight pipe 112 from being blocked by residues.

[0032] The present invention also provides another technical solution, a fatty acid refining and distillation process, comprising the following steps: S1: injecting the fatty acid to be distilled into the inner cylinder 9, and then turning on the electric heating rod 102 to distill the fatty acid.

At the same time, the refrigeration tube 6 is connected to the external refrigerator, and the cold air generated by the refrigerator enters the refrigeration tube 6, thereby cooling the vaporized fatty acid in the annular tube 7 and turning it into liquid fatty acid, completing the distillation. At this point, all the distillation processes are completed.

[0033] Specifically, when the transmission rod 251 starts to rotate, it will drive the lower connecting block 282 to rotate, and then drive the primary sleeve 2861, the secondary sleeve 2862 and the tertiary sleeve 2863 to rotate. Since the lower connecting block 282 does not correspond to the center of the inner cylinder 9, and one end of the tertiary sleeve 2863 is in contact with the inner wall of the inner cylinder 9, with continuous rotation, the tertiary sleeve 2863 will be compressed into the secondary sleeve 2862, and the secondary sleeve 2862 will be compressed into the primary sleeve 2861. Inside the inner tube 61, the three groups of scrapers 2865 will also be compressed together. While rotating, the scrapers 2865 will scrape off the slag at the bottom of the inner tube 9. During the rotation, the outer surface of the roller 2868 is close to the inner wall of the inner tube 9. During the rotation, as the first-level sleeve 2861, the second-level sleeve 2862 and the third-level sleeve 2863 are continuously compressed, the arc plate 2866 will gradually pull the scraped residue to the middle position near the bottom of the inner tube 9 to facilitate the discharge of the residue.
