Description

Technical Field

[0001] The utility model relates to a blending kettle, in particular to a lubricating oil blending kettle. Background Art

[0002] Lubricants are generally composed of two parts: base oil and additives. Base oil is the primary component of lubricants and determines their fundamental properties. Additives compensate for and improve base oil performance deficiencies, imparting new properties and becoming a crucial component of lubricants. By adding different additives, different types of lubricants can be blended, such as gear oil, hydraulic oil, and wire lubricant.

[0003] A lubricating oil blending kettle is a device that fully mixes base oil and additives and has the function of regulating temperature. Existing blending kettles generally stir the base oil and additives by setting a rotating vertical shaft inside the blending kettle and fixing a number of stirring rods on the vertical shaft. This stirring method causes the mixed oil composed of the base oil and additives to rotate radially within the kettle body. Since the mixed oil rotates in a single direction and forms a stable rotation mode, this stirring method cannot quickly and evenly stir the lubricating oil. Utility Model Content
