Description

Technical Field

[0001] The invention belongs to the technical field of vegetable oil acid polyether processing equipment, in particular to a solvent mixing device for vegetable oil acid polyether. Background Art

[0002] ‌ Vegetable oleic acid is a natural unsaturated fatty acid, which is widely found in various vegetable oils, such as olive oil, linseed oil, soybean oil, rapeseed oil and peanut oil. Vegetable oleic acid has good fluidity at low temperatures and high thermal stability. It is the most widely found natural unsaturated fatty acid, and contains a carbon-carbon double bond in its molecular structure. It is usually a colorless or light yellow oily liquid and has a wide range of uses in industry. Oleic acid is a common auxiliary material used in polyether production and can be used to control the acidity during the polyether reaction. In the process of mixing oleic acid and polyether, only stirring for mixing is prone to incomplete mixing. Therefore, some mixing devices have ultrasonic vibration devices for vibration mixing, which can make the solvents to be mixed produce high-frequency vibrations, so that different solvents can be better mixed. However, the cavity of the mixing equipment is generally large, and the existing ultrasonic vibration device is generally fixedly installed on the outer wall or inner wall of the cavity, and the mixing equipment is generally provided with an agitator for stirring the mixed solvent. The rotation of the agitator paddle makes it difficult to set the ultrasonic vibration device within the rotation range of the agitator paddle. Therefore, it is difficult to vibrate the mixed solvent well at various places in the cavity of the mixing equipment with the ultrasonic vibration device, resulting in uneven ultrasonic vibration mixing. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a solvent mixing device for vegetable oil acid polyether. In the solvent mixing device, an ultrasonic vibration device is arranged on a stirring paddle.
