Description

Technical Field

[0001] The utility model belongs to the technical field of stearic acid preparation, and particularly relates to a separation and extraction device for stearic acid preparation. Background Art

[0002] Stearic acid is a fatty acid that is widely present in nature. Almost all oils and fats contain stearic acid in varying amounts. Decomposing agents are added to hardened oil, which is then hydrolyzed to obtain crude fatty acids, which are then washed, distilled, and bleached to obtain the finished product.

[0003] The utility model patent with publication number CN216663002U discloses a stearic acid preparation, separation and extraction equipment, including a servo motor, a turntable, a connecting disk, balls, and a separation tank. A servo motor is fixedly installed inside one side of a separation shell, and a connecting disk is fixedly installed on one side of the separation shell close to the outside of the servo motor. The servo motor is connected to the turntable through the output shaft passing through the connecting disk on one side, and balls are arranged on the connecting disk and the turntable through grooves. A separation tank is fixedly installed on the other side of the turntable. When the device heats oil raw materials and water, water vapor is generated. Since the water vapor contains other substances, if it is directly discharged, it will pollute the surrounding environment and cause harm to the workers' health. The impurities generated flow out along the water flow holes on the upper side of the separation tank. If too many impurities accumulate, it is easy to cause blockage. Therefore, a separation and extraction device for stearic acid preparation is proposed. Utility Model Content
