Description

Technical Field

[0001] This utility model relates to the field of oil processing technology, and in particular to a distillation device for separating pesticide residues in lanolin. Background Technology

[0002] Lanolin is a natural animal fat secreted from sheep glands and attached to wool. It is widely used in cosmetics, skin care products, and pharmaceuticals and food. However, since pesticides may be sprayed during the wool farming process to repel insects, pesticide residues may remain in lanolin, which could pose a potential threat to human health. Therefore, it is necessary to remove pesticide residues from lanolin.

[0003] Currently, pesticide residues in lanolin are mainly separated by distillation. After the lanolin is preheated and liquefied, it is lowered by vacuum distillation equipment and then heated to vaporize. Separation is achieved based on the different boiling points of lanolin and pesticides. However, existing distillation equipment mainly heats the lanolin liquid uniformly at the bottom of the still, which results in low heating and vaporization efficiency, long overall distillation time, and low efficiency in removing pesticide residues. Utility Model Content

[0004] In view of the problem of low heating vaporization efficiency of lanolin in the above-mentioned or existing technologies, this utility model is proposed.

[0005] Therefore, the purpose of this invention is to provide a distillation apparatus for separating pesticide residues in lanolin.

[0054] Furthermore, the gap adjustment mechanism 3 also includes multiple transmission ramps 34 fixed on the inner wall of the transmission plate 33. The platform of the transmission ramp 34 is in contact with the groove surface of the push ramp 322. The transmission ramp 34 slides in contact with the groove surface of the push ramp 322. Multiple transmission columns 222 penetrating the side wall of the hollow rotating shaft 23 are fixed on the outer wall of the transmission plate 33. The transmission columns 222 are movably connected to the hollow rotating shaft 23 and the connection is sealed. An mounting plate 221 is fixed on the outside of the transmission column 222. The mounting plate 221 is fixedly connected to the scraper plate 22.

[0055] Specifically, the push-back component 35 includes a fixed cylinder 351 disposed outside the transmission plate 33, and a spring 352 is disposed inside the fixed cylinder 351.

[0056] Furthermore, the push-back component 35 includes a fixed cylinder 351 fixed to the outer wall of the transmission plate 33 with an outward opening. A spring 352 is fixed inside the fixed cylinder 351. The spring 352 is placed radially along the hollow rotating shaft 23 and one side is fixed inside the fixed cylinder 351. The other side of the spring 352 abuts against the inner wall of the hollow rotating shaft 23.

[0057] Specifically, it also includes a vacuum mechanism 4, which includes a vacuum body 41 located at the side of the distillation tank 1. The vacuum body 41 is provided with a connecting pipe 43 connected to the distillation tank 1, and the connecting pipe 43 is provided with a switch valve 42.

[0058] Furthermore, a vacuum mechanism 4 is installed on the side of the distillation tank 1;

[0059] The vacuum mechanism 4 includes a vacuum pump body 41 fixed to the side of the distillation tank 1. The vacuum pump is existing technology and is used to evacuate and reduce the pressure inside the distillation tank 1. The output end of the vacuum pump body 41 is fixed with a connecting pipe 43 connected to the distillation tank 1. A switch valve 42 for opening and closing the connecting pipe 43 is installed in the middle of the connecting pipe 43.

[0060] When using the distillation process to remove pesticide residues from lanolin, preheated liquid lanolin is introduced into the distillation tank 1 through the discharge pipe 13. After the lanolin liquid is introduced and the discharge pipe 13 is sealed, the vacuum pump body 41 is started. After the vacuum pump body 41 evacuates the inside of the distillation tank 1, the heating wall 12 and the servo motor 21 are started. The servo motor 21 drives the hollow rotating shaft 23 to rotate. The hollow rotating shaft 23 drives the mounting plate 221 to rotate through the transmission column 222, which in turn drives the scraper plate 22 fixed on the mounting plate 221 to rotate. When the scraper plate 22 rotates, it stirs the lanolin liquid at the bottom of the distillation tank 1. The lanolin close to the wall of the distillation tank 1 is stirred up by the scraper plate 22 and some of the lanolin is scraped onto the surface of the heating wall 12, forming a thin lanolin liquid film on the surface of the heating wall 12. As the heating plate heats up, the pesticide residues in the lanolin liquid film vaporize and evaporate, and are transported to the condensation equipment for condensation and recovery through the discharge pipe 111.

[0061] During the multi-stage distillation process, the heating temperature of each stage of the heating wall 12 is different. When the heating temperature is low and the liquid film is thick, the evaporation efficiency is reduced. When the heating temperature is high and the liquid film is thin, it is easy to overheat and cause the material to coke. To avoid the above situation, the internal small electric push rod 31 needs to be activated to adjust the gap between the scraper plate 22 and the heating wall 12.

[0062] When adjusting the gap between the scraper plate 22 and the heating wall 12, the small electric push rod 31 is activated. The small electric push rod 31 drives the movable column 32 to move up and down. When the movable column 32 moves upward, the transmission platform 321 on the movable column 32 moves upward. The transmission platform 321 pushes the transmission inclined platform 34 that is in contact with the transmission platform 321 outward by pushing the inclined groove 322. The transmission inclined platform 34 drives the transmission plate 33 to move outward. The transmission plate 33 drives the mounting plate 221 and the scraper plate 22 to move outward through the transmission column 222. At this time, the gap between the scraper plate 22 and the heating wall 12 becomes smaller, and the liquid film formed by the rotation of the scraper plate 22 becomes thinner, which is suitable for distillation treatment at lower heating temperatures.

[0063] When the movable column 32 moves downward, the transmission platform 321 on the movable column 32 moves downward, making the inner side of the transmission ramp 34 free up space. At this time, the spring 352 pushes the transmission plate 33 towards the axis of the hollow rotating shaft 23, causing the transmission plate 33 to retract inward. The transmission plate 33 drives the mounting plate 221 and the scraper plate 22 to move inward through the transmission column 222. At this time, the gap between the scraper plate 22 and the heating wall 12 becomes larger, and the liquid film formed by the rotation of the scraper plate 22 becomes thicker, which is suitable for distillation treatment at higher heating temperatures.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
