Description

Technical Field

[0001] The utility model relates to the technical field of dihydroterpineol preparation, and more specifically to a fractionation device for preparing dihydroterpineol. Background Art

[0002] Dihydroterpineol is a raw material for blending lilac flavor with good performance. The usage in soap and synthetic detergent flavors can reach 20%. Compared with terpineol, dihydroterpineol has more woody aroma and is suitable for flavoring heavy detergents. It has stable performance and is widely used in the formulation of daily chemical flavors. In the preparation process of dihydroterpineol, a fractionation device is needed to separate the substances.

[0003] After searching, the utility model patent with announcement number CN212548357U discloses a distillation device for preparing dihydropinene alcohol, whose structure includes a connecting pipe, a conveying pipe, a driving machine, a sealing cover, a collecting tank, a supporting foot, a distillation tank, a connecting branch pipe, and a conversion tank. The utility model discloses a distillation device for preparing dihydropinene alcohol. When the distillation tank generates gas by distillation, the gas will come to the pressure groove through the ventilation pipe on the sealing cover shell, and push the extrusion block to slide on the sliding groove, so that the extrusion block applies a certain pressure to the sealing ring. The more gas there is in the distillation tank, the greater the thrust applied by the extrusion block to the sealing ring, so that the inner ring part of the sealing ring is tightly connected with the distillation tank connecting block on the top of the distillation tank, so that the sealing ring on the cover can be pressurized by the gas pressure generated by the distillation of the distillation tank when the equipment is processed, thereby strengthening the connectivity between the sealing ring and the equipment to avoid its relaxation causing gaps and leakage, affecting the normal use of the equipment.

[0004] However, the above patents still have the following shortcomings: some equipment is installed on the cover, which makes the cover as a whole have a certain weight, and the convenience of disassembly is not good. When the fractionation device is running, there is a gas with a high temperature and pressure inside it. At the same time, there are multiple pipes on the fractionation device, which can easily bring danger to the surrounding workers when the pipes leak. For this reason, we propose a fractionation device for preparing dihydroterpineol. Utility Model Content
