This utility model relates to the field of edible oil production technology, specifically to a high-efficiency refining and extraction device for edible oil. To address the technical problem of unagglomerated impurities floating in the solution, which do not settle and are difficult to separate, thus affecting refining quality, the device includes: a refining tank, a chute, a slider, a first semi-circular filter plate, a second semi-circular filter plate, a hydraulic cylinder, a cover plate, a semi-circular plate, a conveying shaft, a spiral blade, and a waste removal mechanism. Crude oil undergoes initial filtration through the first semi-circular filter plate. The initially filtered impurities are conveyed to the waste removal mechanism by the upper spiral blade. An electrolyte aqueous solution is added to the crude oil. After sedimentation, the second semi-circular filter plate slides down and engages with the first semi-circular plate. Impurities floating in the aqueous solution are filtered out and adhere to the second semi-circular filter plate. The lower spiral blade scrapes off the sediment on the first semi-circular filter plate and the impurities on the second semi-circular filter plate, conveying them to the waste removal mechanism to complete the impurity removal. This achieves the filtration of large particulate impurities, unprecipitated impurities, and precipitated impurities, resulting in excellent refining performance.

This invention proposes an aniline refining system, including a dehydration mechanism and a distillation mechanism. The discharge pipe of the crude aniline tank in the dehydration mechanism is connected to the cold-side inlet of the first condenser of the distillation column via a dehydration tower feed pump, a dehydration flow meter, and a dehydration regulating valve group. The cold-side outlet of the first condenser is connected to the feed inlet at the top of the aniline dehydration tower. The discharge outlet at the top of the aniline dehydration tower is connected to the first condenser. The condensate outlet of the first condenser is connected to the second condenser. The outlet of the second condenser is connected to the upper liquid inlet of the aniline water stripping tower. This invention allows for multiple impurity removal and purification of crude aniline, improving the refining effect and reducing energy consumption.

The application discloses an oxidation stability reaction kettle for edible oil refining, which comprises a double-layer reaction kettle body, an electric heating plate arranged in the interlayer of the reaction kettle body, and a filter screen detachably arranged in a crude oil inlet pipe. During use, the electric heating plate can ensure the reaction temperature in the reaction kettle body, the crude oil can enter the reaction kettle body through the crude oil inlet pipe, and the impurities in the crude oil can be filtered through the filter screen, so that the functional diversity of the reaction kettle is improved. The auxiliary materials can be added into the reaction kettle body through an auxiliary material inlet pipe, a plurality of stirring rods are fixed to a stirring shaft, and the stirring rods in the same layer are fixed with a scraper at one end. The starting driving motor can drive the stirring shaft and the stirring rods to rotate, so that the materials in the reaction kettle body are stirred and uniformly mixed, the reaction is uniformly promoted, the refining effect is improved, the grease on the inner wall of the reaction kettle can be scraped off through the scraper, the service life of the reaction kettle is prolonged, and the edible oil can be discharged through a discharge pipe after the refining is completed.
