Description

Technical Field

[0001] This utility model relates to the field of lubricating oil processing, specifically a blending device for lubricating oil processing. Background Technology

[0002] Lubricating oil is a technology-intensive product, a complex mixture of hydrocarbons. Its actual performance is the result of a combination of complex physical or chemical changes. It generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines its basic properties. Additives can compensate for and improve the shortcomings of base oil performance, and impart certain new properties. They are an important part of lubricating oil.

[0003] Chinese Patent CN217646275U discloses a blending device for lubricating oil production and processing, including a blending installation shell, a feeding and weighing component on one side of the blending installation shell, a blending component inside the blending installation shell, and a filter cleaning component at the bottom of the blending component. An additive is fed into a weighing hopper via a feeding pipe. After weighing by a weighing sensor, the weighing sensor closes the discharge valve in the feeding pipe and opens the discharge valve in the discharge pipe, allowing the weighed additive to be discharged into the blending installation shell through the discharge pipe. An outlet pipe and outlet valve allow the blended material to be discharged through the outlet pipe. However, in the aforementioned patent, the additive needs to be weighed by a weighing sensor before being injected into the blending installation shell. This method results in slow additive metering and requires repeated mixing and adjustment of the additive, reducing the blending speed during lubricating oil processing. Therefore, those skilled in the art have provided a blending device for lubricating oil processing to solve the problems mentioned in the background art. Utility Model Content
