Description

Technical Field

[0001] The utility model relates to the technical field of petroleum ether extraction, in particular to a petroleum ether extraction and separation device. Background Art

[0002] Petroleum ether is a colorless, transparent liquid with a kerosene smell, mainly a mixture of pentane and hexane. Petroleum ether is insoluble in water, but soluble in most organic solvents such as anhydrous ethanol, benzene, and chloroform. It is mainly used as a solvent and for oil and fat treatment. A separation device is required during the processing of petroleum ether.

[0003] The petroleum ether extraction separation device can accurately control the separation process, such as controlling the standing time to ensure sufficient stratification, and can easily export different phases as needed.

[0004] In the existing petroleum ether extraction and separation device, when the mixture is placed in the separation device, since there are some impurities such as solid particles and insoluble substances in the mixture, if the impurities are not removed, the impurities may interfere with the extraction process and affect the extraction efficiency and effect. Therefore, the mixture needs to be pre-filtered when entering the extraction tank, and when the mixture is poured onto the surface of the filter plate, it is usually concentrated on the central area of ​​the filter plate. Concentrated filtration will result in low filtration efficiency of the mixture, and the filter plate will be blocked by impurities in the mixture, resulting in a situation where filtration cannot be performed. To address this problem, we propose a petroleum ether extraction and separation device. Summary of the invention
