Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model can be by right
Require that the multitude of different ways limiting and covering is implemented.
Refer to Fig. 1 and Fig. 2, this utility model provides a kind of oil separation device, and it is particularly well-suited to huge discharge screw rod pressure
Contracting machine, can not result in the big pressure loss while being effectively improved oil point effect.
As depicted in figs. 1 and 2, the oil separation device in this utility model includes staving 1, air vent 2 and oil point filter screen 3.Oil
Divide filter screen 3 to be arranged in staving 1, staving 1 is divided into the first space and two part (preferred oil of second space of axial distribution
Point filter screen 3 is arranged along the sagittal plane of staving 1), air vent 2 is positioned at described first space, and the discharge directions of air vent 2 with
The tangential direction of staving 1 inwall is consistent.Preferably, in this utility model, the air vent 2 of oil separation device is arranged on exhaust shaft bearing
On 10, and be positioned at the first space, more particularly, the discharge directions of air vent 2 as illustrated by the arrows in fig. 1, i.e. aerofluxus
The discharge directions of mouth 2 is along the tangential direction of staving 1 inwall.For ensureing that the air-flow discharged from air vent 2 is fully rotatable.Preferably,
Spacing A between air vent 2 and oil point filter screen 3 is more than 300mm, and wherein, spacing A is air vent 2 one end near oil point filter screen 3
And oil divides the filter screen 3 distance between the side of air vent 2.
When gas mixture is after air vent 2 is discharged, will along the tangential flowing of staving 1 inwall, thus have whirlwind from
The effect that the heart separates, makes air-fuel mixture air-flow flow through oil point filter screen 3 the most again, thus can be effectively improved what compressor oil divided
Effect, avoids using extra rotation separation structure to cause the pressure loss simultaneously, the problem causing compressor efficiency, have simple in construction,
The feature of low cost.
In one embodiment, staving 1 inwall is provided with multiple fixed block 11, oil point filter screen 3 by screw and these
Fixed block 11 is fixed, thus is installed to the inside of staving 1.
Preferably, oil separation device also includes flow-stopping plate 4 and exhaustor 5, and wherein, exhaustor 5 and air vent 2 lay respectively at institute
State the both sides of oil point filter screen 3, more specifically, on the sidewall of exhaustor 5 second space that is arranged on staving 1.In order to reach inertia
The purpose separated, in flow-stopping plate 4 is arranged on second space by this utility model and make flow-stopping plate 4 be in the entrance of exhaustor 5 with
Position between oil point filter screen 3, more preferably can be arranged substantially in parallel flow-stopping plate 4 with oil point filter screen 3, it is clear that flow-stopping plate 4 is also
