Description

Technical Field

[0001] The utility model relates to the technical field of oil mist separation, in particular to an oil mist separator. Background Technique

[0002] The oil mist separator, also known as the oil mist recovery machine and the oil mist collector, only has different names. The oil mist separator is installed on various machining equipment such as CNC machining centers, washing machines, die-casting machines, and CNC lathes to suck the oil mist in the machining cavity, so as to purify the air and protect the health of workers. The oil mist separator device is to timely discharge the oil fume in the fuel tank or bearing box to keep the pressure in the fuel tank at a slightly negative pressure of -0.5~-1 kPa, and the slightly negative pressure in the bearing box is controlled at -50 Pa;

[0003] In the existing oil mist separation method, the solid particles in the inhaled medium are first intercepted. By thoroughly intercepting the larger solid and dust particles in the front section, the high-pressure collision centrifugal separation intercepts the liquid-phase mist;

[0004] If the conventional oil mist separation method is used to process the oil fume in the bearing box, there will be some problems. For example, although the oil fume separates the oil, there are still some harmful gases polluting the air, the oil flow cannot be recovered and returned, and the airtightness is relatively low. Therefore, we propose an oil mist separator. Content of the Utility Model
