Description
Technical Field
The utility model relates to an oil gas automatic formula separation technical field, concretely relates to centrifugal formula oil and gas separator separation piece and oil and gas separator for vehicle engine crankcase oil-gas separation.
Background
The oil-gas separator is utilized by people as early as the nineteenth century, but the oil-gas separator is still used on automobile engines in the sixties of the last century, and the research on oil-gas separation technology in China is still later. During this period, many workers and researchers at home and abroad have conducted research work on separators, and have progressed from the initial experimental exploration stage to the research period of today's combination of theory and experiment. At present, the structural form of the oil-gas separator is various, but the design standard and the specification are not uniform. Under the background of higher and higher separation efficiency requirements, most researchers at home and abroad tend to a two-stage or multi-stage separator.
The working principle of the active centrifugal oil-gas separator is that a rotating vortex is formed in the separator by means of external input energy, and particles in mixed gas flow are separated out under the action of centrifugal force. A conical active centrifugal separator is usually used, in which a plurality of conical discs are mounted on a rotating shaft, small holes are provided in the discs near the rotating shaft, which are the channels for the mixture to flow through, and a set of curved blades is provided on each disc. When the rotating shaft moves, the mixed gas is thrown out along the annular space between the conical discs under the action of centrifugal force, so that the purpose of oil-gas separation is achieved. Due to the fact that the manufacturing and using cost of the active centrifugal oil-gas separator is high, the active centrifugal oil-gas separator is mostly applied to an aero-engine at present.
At present, two types of separation sheets are used in a centrifugal oil-gas separator. One is a disc with a conical shape and a flanging; however, due to the adoption of the flanging structure, oil which is captured by the conical part and thrown to the flanging in the using process is easy to be at the transition position of the flanging and the conical part, so that the weight is increased, the gravity center is easy to shift, the rotating speed of the separating assembly is reduced, and the separating efficiency is reduced. The other is a conical disk, and the disk is provided with an arc-shaped separating element; however, the provision of the curved dividing elements causes the oil droplets on the disk to move along the curved dividing elements, which increases the residence time of the oil droplets on the disk, and also causes the weight of the entire separation disk to increase during use, the rotational speed of the separation assembly to decrease, and the separation efficiency to decrease.
SUMMERY OF THE UTILITY MODEL

Because a plurality of oil blocking bulges extending along the generating line are adopted, oil particles caught on the oil thrower can be thrown out along the shortest distance on the oil thrower under the action of the oil blocking bulges, so that the retention time of the oil particles on the oil thrower is reduced, the rotational stability of the oil thrower is ensured, and the efficiency and the stability of oil-gas separation are further improved.
As an improvement, the cross section of the oil baffle projection is of an arc or triangular structure; after the arrangement, the oil blocking protrusion is in line contact with the adjacent oil thrower disc, so that when oil particles are accumulated to a certain amount at a certain position in the rotating process, accumulated oil accumulated at the position is easy to enter the next area through the contact position of the oil blocking protrusion and the adjacent oil thrower disc, the influence of the accumulated oil on the rotating speed of the oil thrower disc is reduced, and the efficiency and the stability of oil-gas separation are ensured.
