Description

Technical Field

[0001] The utility model relates to the technical field of oil mist separators, in particular to an oil mist separator with a filter element that is easy to replace. Background Art

[0002] Oil mist separator, also known as oil mist recovery machine, oil mist collector, is a kind of oil mist separator installed on various machining equipment such as CNC machining centers, cleaning machines, die-casting machines, CNC lathes, etc., to absorb the oil mist in the machining chamber to purify the air and protect the health of workers.

[0003] When replacing the filter element of the existing oil mist separator, it is necessary to first remove the bolts on the oil mist separator and then open the cover to take out the replacement filter element. After the filter element is replaced, the cover must be closed and the bolts must be tightened one by one. This is very troublesome to replace the filter element and is not efficient. In addition, the oil mist sucked away by the oil mist separator will carry certain solid particles, and the solid particles will easily deposit on the filter element, which will cause the filter element to be blocked and reduce the service life of the filter element. For this reason, we propose an oil mist separator that is easy to replace the filter element. Utility Model Content
