Description

Technical Field

[0001] The utility model belongs to the technical field of environmental protection, and particularly relates to a solid-liquid separator capable of automatically discharging slag. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays roles such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. It is applied between two relatively moving objects and can reduce the friction and wear generated due to the contact of the two objects. With the progress of technology, the development direction of oil regeneration technology and waste oil recovery is inevitable. Lubricating oil is no longer a consumable. Keeping the oil free of moisture and impurities and being able to extend the oil life by more than 10 years has always been the goal of current manufacturers.

[0003] During the production process of lubricating oil, there will be some solid particle impurities in the lubricating oil. These solid particle impurities will affect the lubricating effect of the lubricating oil and its use. Therefore, lubricating oil solid-liquid separation equipment is needed to remove the impurities in the lubricating oil. 80%-90% of the hydraulic system failures are caused by oil pollution. Therefore, precision oil filtration equipment has become an essential tool in the hydraulic industry. At present, most of the solid-liquid separation physical filtration on the market uses consumables such as filter cloth, filter element, activated carbon, and permeable membrane for filtration. In actual application, these consumables need to be replaced frequently, wasting funds and working hours, and the discharged slag may have a high water content and may require secondary treatment. Therefore, reducing the consumption of consumables during the production process is a key purpose in the production process of lubricating oil. Summary of the Utility Model
