Problems solved by technology
[0004] However, after multi-stage filtration, the existing filtering device cannot reflow and repeatedly filter the filtered lubricating oil, so that after multi-stage filtration, there are still some particles and impurities in the lubricating oil, which makes the purity of the lubricating oil poor and reduces Lubricating oil production efficiency

The invention discloses a multistage filtering mechanism for lubricating oil production, which comprises a filtering bin, a stirring assembly is arranged on the filtering bin, the stirring assembly divides the inner cavity of the filtering bin into a first cavity, a second cavity and a third cavity through a filtering unit, and a feeding pipe is arranged at the top of the filtering bin. The outlet end of the filtering bin is connected with the storage bin through a discharging pipe, a third three-way valve is arranged on the discharging pipe and communicates with the first cavity through a circulating pipe, and a second backflow assembly and a first backflow assembly which communicate with the second cavity and the third cavity correspondingly are arranged on the circulating pipe. According to the filtering mechanism, the multiple independent and communicated cavity structures are adopted, and the backflow mode of the backflow assembly is combined, so that filtered lubricating oil can be guided into the filtering bin again to be subjected to circulating filtering treatment, it is ensured that impurities in the lubricating oil can be filtered out, the purity of the lubricating oil is greatly improved, and the service life of the lubricating oil is prolonged. And the production efficiency of the lubricating oil is improved.
Description
technical field [0001] The invention relates to the technical field of lubricating oil production, in particular to a multi-stage filtering mechanism for lubricating oil production. Background technique [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 the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil is the best The main properties are viscosity, oxidation stability and lubricity. In the production of lubricating oil, it is necessary to mix the base oil and additives and mix them in the blending tank. There will be some mechanical impurities in the base oil, such as sand and iron filings. , In the process of adding additives to the base oil and blending, intolerant metal salt precipitates will be formed, so the lubricating oil must be treated by a filter device after blending ...
