Description

Technical Field

[0001] The utility model belongs to the technical field of waste oil recovery, in particular to a waste oil recovery and refining process vacuum unit. Background Art

[0002] Waste oil refers to oil that is purified from crude oil or synthesized and contaminated by physical or chemical impurities after use. Simply put, waste oil, as the name suggests, is oil that comes from petroleum or synthetic oil and has been used.

[0003] During use, impurities such as dust, metal chips, water or chemicals may be mixed with oil and are considered waste oil. Waste oil is difficult to maintain subsequent work, so it is necessary to recycle the waste oil. The existing waste oil is often recycled and refined through a vacuum oil filter. However, the filter screen will inevitably become clogged during the long filtration process. Although the staff can replace it, the entire equipment needs to be stopped, which leads to low efficiency of the equipment in waste oil recovery and processing, thereby reducing the practicality of the equipment.
