During the oil filtration process, the filtered oil may contain more impurities, so it is necessary to install a filter on the oil filtration pipeline to filter out the impurities. However, most of the current vacuum oil filtration devices can block most of the impurities through the filters they have set up, but there are still smaller impurities that enter the device through the filters, affecting the oil filtration effect. Therefore, we propose a double-filtration vacuum oil filtration device to solve the above problem. Utility Model Content
