Description

Technical Field

[0001] This utility model relates to the field of hexane processing technology, and in particular to a distillation apparatus for hexane extraction. Background Technology

[0002] Hexane, with the molecular formula C6H14, is an alkane containing six carbon atoms. It has five isomers: n-hexane, 2-methylpentane, 3-methylpentane, 2,3-dimethylbutane, and 2,2-dimethylbutane. Among them, n-hexane can be used as a good organic solvent and is widely used in chemical organic synthesis, vegetable oil extraction, and cleaning and decontamination of mechanical equipment. At room temperature, hexane is always liquid. When processing and extracting hexane, a distillation device can be used. Distillation is a separation process that uses the different volatility of components in a mixture to separate the components. Commonly used equipment includes plate distillation columns and packed distillation columns.

[0003] To this end, Chinese patent application number CN217077269U discloses an extractive distillation device for acetonitrile recovery from pharmaceutical wastewater. The aim is to provide an integrated extractive distillation device for acetonitrile recovery and utilization. The key technical point is that this extractive distillation device for pharmaceutical wastewater includes a distillation column with a distillation chamber at the bottom and a reboiling device within the distillation chamber. It also includes a distillation chamber located above the distillation chamber; an extraction chamber located above the distillation chamber and adjacent to it; a condensation chamber located above the extraction chamber and connecting it to the distillation chamber; and a cooling chamber installed above the distillation chamber and condensation chamber and connected to both the distillation chamber and extraction chamber. By setting up the distillation chamber, condensation chamber, and extraction chamber, pharmaceutical wastewater enters from the distillation chamber, passes through the condensation chamber and extraction chamber, and then flows out as acetonitrile liquid from the distillation chamber. This device has high treatment efficiency, effectively recovers and utilizes acetonitrile from pharmaceutical wastewater, and has a small footprint, making it suitable for widespread application. This utility model is applicable to pharmaceutical wastewater treatment.

Utility Model Content

[0005] The purpose of this invention is to provide a distillation apparatus for hexane extraction, which solves the problem that existing distillation apparatuses for hexane extraction are difficult to recover heat.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a distillation device for hexane extraction, including a base;

[0007] The base has a housing at its top, an inlet at its top, and a connecting pipe on one side of the housing.

[0008] An outlet is installed at the bottom of one side of the outer shell, a connecting pipe is installed at the top of one side of the outer shell, and a housing is installed on one side of the connecting pipe. A cooling pipe is embedded inside the housing, and a recycling mechanism is installed at the top of one side of the outer shell.

[0009] The recycling mechanism includes a discharge pipe installed at the top of one side of the outer casing, a filter screen installed on one side of the discharge pipe, a discharge pump installed on one side of the discharge pipe, and a flange installed on one side of the discharge pipe.

[0010] In use, the material is first loaded into the shell through the inlet. Then, the heating wire heats and evaporates the material for extraction. The extracted material enters the shell through the connecting pipe. Then, the cooling pipe cools the material. The remaining material in the shell can be discharged through the outlet. The outlet can be connected to other pipes through the first and second flanges. The fixing screws and nuts form a threaded connection, and the flanges can be fixed together by fixing the screws and nuts.

[0011] Furthermore, a heating wire is installed inside the outer casing. The heating wire is serpentine in shape and can penetrate into the interior of the outer casing.

[0012] Furthermore, a stirring mechanism is installed inside the outer shell. The stirring mechanism includes a servo motor installed at the bottom of the outer shell, a stirring shaft installed at the top of the servo motor, and stirring blades installed on the outside of the stirring shaft. The stirring blades can stir the hexane material inside the outer shell.

[0013] Furthermore, a scraper is installed on one side of the stirring blade, and the scrapers are symmetrically distributed about the central axis of the stirring shaft. The scraper can clean the inner wall of the outer shell.

[0014] Furthermore, a connection structure is installed on one side of the outlet. The connection structure includes a second flange installed on one side of the outlet, a first flange installed on one side of the second flange, a fixing screw installed on the outside of the second flange, and a nut installed on one side of the fixing screw. The outlet can be connected to other pipelines through the first flange and the second flange.

[0015] Furthermore, the outer side wall of the fixing screw is uniformly provided with external threads, and the inner side wall of the nut is uniformly provided with internal threads that cooperate with the external threads. The fixing screw and the nut are threadedly connected, and the flange can be fixed together by fixing the fixing screw and the nut.

[0016] Furthermore, the inner diameter of the nut is larger than the outer diameter of the fixing screw, the nuts are arranged in a ring, and the nuts and fixing screw form a threaded connection.

[0017] The distillation equipment for hexane extraction provided by this utility model has the following advantages: during use, it can absorb the internal heat and send it to other devices for recycling, making the device more energy-efficient and environmentally friendly. At the same time, it can enhance the evaporation speed and uniformity through stirring, making the device work more efficiently.

[0018] By installing a discharge pump on one side of the discharge pipe, the pump generates suction, which draws out hot gas from inside the casing. The hot gas can then be drawn out through the discharge pipe, which can be connected to other pipes via a flange. The hot gas passing through the discharge pipe can be filtered through a screen to prevent dust from entering the pipe. The hot gas can then enter different devices through the discharge pipe and other pipes, allowing for heat recovery and reuse. This makes the device more energy-efficient and environmentally friendly, thus achieving the goal of facilitating heat recovery in distillation equipment used for hexane extraction.

[0019] By installing a servo motor inside the base, the servo motor can drive the stirring shaft to rotate. The rotation of the stirring shaft will drive the stirring blade to rotate, which will stir the material inside the shell, making the material evaporate better. At the same time, the rotation of the stirring blade will drive the scraper to rotate, which can clean the inner wall of the shell. This achieves the purpose of improving the working efficiency of the distillation equipment used for hexane extraction. Attached Figure Description
