Description

Technical Field

[0001] The present invention belongs to the technical field of lanolin extraction devices, and particularly relates to a tower-type integrated anhydrous lanolin extraction device. Background Art

[0002] Lanolin is an oily secretion attached to wool. Its main components are esters formed by sterols, fatty alcohols, triterpenols and approximately equal amounts of fatty acids, and also contain free alcohols, free acids, hydrocarbons, etc.

[0003] Chinese Patent (CN201110119744.1) discloses a method for extracting lanolin from wool washing wastewater sludge. The steps are as follows: the wool washing wastewater sludge is dried with hot air until the moisture content of the sludge is less than 15%; petroleum ether, alkane or halogenated alkane is used to extract lanolin from the sludge, and the dosage of the extractant is 4-5 times the weight of the sludge, and the extract is obtained by filtration; sulfuric acid with a volume of 2-3% of the extract and a concentration of 5wt% is added, and the mixture is stirred at 60-70°C for 30 minutes, and after standing for 1 hour, the upper layer solution is taken and a solution containing 15wt% ethanol and 3wt% sodium hydroxide is added. The volume of the added solution is 2 times the volume of the sulfuric acid added above, and the mixture is stirred at 60-70°C for 30 minutes, and after standing for 1 hour, the upper layer solution is taken; it is washed with an equal volume of 50wt% ethanol solution; the extractant in the solution is removed by vacuum evaporation.

[0004] Chinese Patent (CN201310529025.6) discloses a method for extracting lanolin from wool washing wastewater sludge by extractive distillation, belonging to the field of wool washing sludge treatment. The method for extracting lanolin of the present invention includes: mixing extraction - sedimentation separation - rectification - packaging. This method uses petroleum ether as the extractant. After mixing and extracting the sludge and petroleum ether, it is put into a sedimentation tank for sedimentation separation, and the separated liquid phase enters a rectification tower for rectification, so as to obtain lanolin with high purity and high recovery rate.

[0005] Chinese Patent (CN201310468111.0) discloses a method for recovering lanolin and potassium salts from wool washing wastewater and sludge, including: recovering lanolin from the neutral wool washing closed-loop wastewater treatment concentrate, preparing compound potassium fertilizer from the waste soil of the neutral wool washing wastewater and sludge closed-loop for recovering lanolin, and recovering sheep sweat and potassium salts from the neutral wool washing wastewater closed-loop by reverse osmosis treatment.

[0006] Currently, when extracting lanolin from wool washing sludge, the production line can only meet the requirement of processing a certain amount of sludge at a time, resulting in poor extraction coherence of the extraction device. And when extracting the lanolin component dissolved in petroleum ether, it is necessary to use multiple stirring tanks to add medicine multiple times and then take the supernatant. Not only is the treatment process long, reducing the extraction efficiency of lanolin, but also a large number of stirring tanks are invested, occupying a large amount of factory space.

[0053] A feeding port 17 is arranged on the sludge tank 5, facilitating the injection of the sludge after the washing wool wastewater is precipitated.

[0054] Working principle: First, the sediment sludge of wool scouring wastewater is added into the sludge tank 5 from the feeding port 17. The second rotating motor 65 rotates to drive the screw rod 63 to rotate. The rotation of the screw rod 63 vertically conveys the sludge in the sludge tank 5 in the main pipe body 61. The sludge is heated and dried by the heater 64 in the main pipe body 61. The dried sludge enters the cooling and distributing tank 62 for cooling. The cooling fan 16 blows air into the cooling and distributing tank 62 to accelerate the cooling of the sludge. Under the guiding action of the guiding cover 15, the dried sludge enters the main tank body 21 from the feeding pipe 9 with the control valve 13 opened. Secondly, before the dried sludge enters the main tank body 21, multiple telescopic devices 23 drive the multi-layer partition plates 22 to slide in the slideway 14 respectively to keep multiple reaction chambers 8 in a connected state.

Multiple first rotating motors 25 drive multiple stirring paddles 24 to rotate all together. After stopping stirring, precipitation occurs. The telescopic device 23 at the bottom drives the partition plate 22 to slide in the slideway 14. The partition plate 22 separates the precipitate below it and the supernatant above it. Sulfuric acid is added from the medicine adding port 10. Except for the first rotating motor 25 in the already closed reaction chamber 8 not being powered, multiple other first rotating motors 25 drive multiple stirring paddles 24 to rotate all together. After stopping stirring, precipitation occurs. Repeat the above operations to add ethanol, sodium hydroxide, etc. in sequence until the partition plate 22 at the top layer separates the lanolin mixture in the reaction chamber 8 above it. Then, the control valve 13 of the liquid discharge pipe 12 is opened, and the lanolin mixture enters the distillation tank 4. After evaporating the solution, lanolin can be obtained. Subsequently, the control valve 13 of the liquid discharge pipe 12 is closed. Multiple telescopic devices 23 drive the multi-layer partition plates 22 to slide in the slideway 14 respectively to keep multiple reaction chambers 8 in a connected state. The control valve 13 of the waste discharge pipe 11 is opened, and the waste liquid is discharged into the waste liquid tank 3. Subsequently, the control valve 13 of the waste discharge pipe 11 is closed. Finally, in such a cycle, the cooling and distributing tank 62 continuously supplies the dried sludge to multiple main tank bodies 21 to keep the whole device continuously extracting lanolin from the sludge.
