Description

Dish formula centrifugation oil mist separator

Technical Field

The utility model relates to the technical field of mechanical equipment, especially, relate to a can adopt double dynamical mode driven dish formula centrifugal oil mist separator.

Background

Oil lubrication is required for various rotary equipment such as compressors, fans, vacuum pumps, reduction boxes, machine tools and other running parts, and particularly, equipment running at high speed is required. Generally, lubricating oil forms circulating oil or oil mist through an oil pump, or is mixed with compressed air to form oil gas which enters a lubricating point to lubricate high-speed running parts such as bearings, gears and other friction pairs, and the heat is taken away, so that the parts can run reliably for a long time. The sprayed oil and oil mist further form finer oil mist under the action of the centrifugal force of the high-speed rotating component, and the friction heat brought away raises the temperature of the oil to form oil vapor, so that the oil atomization is intensified. The oil vapor accumulates in the tank, increases in temperature and pressure, and seeks to escape through an outlet. For the oil-free compressor, there are two ways to escape for equipment such as fan, firstly, inwards, get into the transport chamber through labyrinth seal, reach the pipeline of low reaches along with the air current, the material that oily gas pollution transported needs absolutely clean not oily gas contact such as flour, milk powder, medicine, secondly, outwards, escape through the sealed of projecting shaft and give off atmospheric environment, continue to inhale the pollution low reaches by equipment, or scatter and be inhaled by the people in the air, form aerosol pollution, influence the personal health, still can cause the oil mass to reduce and need continuously mend oil, the oil that covers in the air still can fall on ground and form wet road surface and influence walking safety. The existing treatment means is a passive treatment technology, namely, the oil mist is simply filtered and then directly exhausted to the atmosphere by opening a hole to install a filtering facility, the advantage is simple, the defect is that the oil mist cannot be guaranteed not to enter a conveying cavity to pollute a downstream product along with air flow, and especially when the air pressure of the conveying cavity is lower than the atmosphere, because the passive power is not provided, the filtering is coarse filtering, the oil mist entering the atmosphere is still more, and the effect is limited. The other is an active treatment technology, namely, a fan is added at the front end or the rear end of an oil mist filter at an exhaust port to provide power, so that oil vapor can pass through a thinner filter with power, thinner oil mist particles are intercepted, and gas enters the atmosphere through the filter, so that cleaner emission is realized. The technology has the advantages of clean discharge and high filtering precision, and has the defects of high power consumption, filter element material consumption and periodic replacement.
