410 and strip plate 420, annular pressing plate 410 is arranged on the outer rim of the both ends of the surface of the 3rd gas-liquid filter net 430, strip plate 420
On the inside of the both ends of the surface for being arranged on the 3rd gas-liquid filter net 430.The mixed gas of secondary filtration structure is flowed through by the three-stage filtration
Discharged after structured filter by the gas outlet 122 at top.Oil return opening also includes three-level oil return opening 113, and three-level oil return opening 113 is arranged on
On bottom plate 110 below three-stage filtration structure.The lubricating oil separated by three-stage filtration structure can be dropped under gravity
On bottom plate 110, the three-level oil return opening 113 on bottom plate 110 is discharged.
Second gas-liquid filter net 330 as described above, the 3rd gas-liquid filter net 430 are wire screen, by wire
Braiding intersected with each other is formed at a certain angle.Wherein, the second gas-liquid filter net 330 is the main composition of the second-order separation section, such as Fig. 2
Shown, its external diameter φ D1, internal diameter φ D2, effective filter thickness are (φ D1- φ D2)/2；3rd gas-liquid filter net 430 is three-level
The main composition of segregation section, its external diameter φ D1, effective filter thickness is L1.Above-mentioned φ D1, φ D2 should be met：(φD1-φD2)>
40mm；Above-mentioned L1 should be met：L1>40mm.
The outer ring surface of annular pressing plate 410 of lower section is welded with outer support circle 310, and welding position has been arranged on hole section and imperforate section
Junction, inner ring surface is connected with the top of inner support circle 320, and the second gas-liquid filter net 330 and the 3rd gas-liquid mistake can be fixed simultaneously
Filter screen 430.It is tangent with the inner ring surface of annular pressing plate 410 and the two ends of strip plate 420 are cylindrical tangent plane, and assemble welding.Due to
Gas-liquid filter net is extruded and the centre of integrated, its upper and lower two surface irregularity, especially both ends of the surface by wire screen
Position.Pass through strip plate 420, it is possible to reduce uneven degree, and to the second gas-liquid filter net 330 and the 3rd gas-liquid filteration
Net 430 applies certain pretightning force.
Further, in order to which the lubricating oil for reducing mixed gas directly spills into gas outlet 122 from fit-up gap, it is surrounding
The annular oil resistance groove 121 of the floor design of flange 120 of gas outlet 122.Annular oil resistance groove 121 be provided with it is multiple, Fig. 3 basis
On, up projected from the bottom surface of flange 120, annular oil resistance groove 121 is the groove structure being made up of 4 annular grooves, groove is preferably
Circular arc.Groove height L3, adjacent two groove distances L4, groove radius R2.
Further, the mixed gas overflowed from fit-up gap reaches the annular collision rift of oil resistance groove 121, collides point
From in order to preferably separate lubricating oil, refrigerant gas, multiple annular oil resistance grooves 121 are designed as lift angle structure, lift angle knot
Structure tilts upward setting by the bottom surface ecto-entad of flange 120 around gas outlet 122 and formed.Now refrigerant gas density it is small,
It is relatively light, 4 annular oil resistance grooves 121 swimmingly can be flowed successively through along lift angle, and hydrodynamic lubrication oil density is big, heavier, need gram
Annular oil resistance groove 121 could be flowed through along lift angle by taking gravity acting, and mixed gas is further separated by self gravitation difference.Its
Middle lift angle size is α, and α typically takes 5 °~20 °.
For the backflow effect of further increase housing bottom, the medial surface of housing bottom is set to recessed circular conical surface, three
Level oil return opening 113 is opened in the summit of circular conical surface.Most of liquid lubricant is under gravity by with recessed taper face
The final three-level oil return opening 113 for gathering center flows to fuel tank, and small part liquid lubricant flows to oil by remaining oil return opening
Case.
The operation principle of oil separating device is illustrated with reference to Fig. 4.Describe for convenience, what ecto-entad was set
Shaft orientation flowing channel 220 is named as the first shaft orientation flowing channel 220, the second shaft orientation flowing channel 220, the 3rd shaft orientation flowing channel 220 and the 4th axle successively
To runner 220.
During work, mixed gas 1 enters the first shaft orientation flowing channel 220 along air inlet 111, into one-level segregation section.Mixing
Gas 1 reaches the bottom surface of flange 120 and occurs to collide for the first time with collision isolating construction 230, the reduction of mixed gas speed, simultaneously
Next shaft orientation flowing channel 220 is flowed to along notch feature.By above procedure, mixed gas there occurs reduction of speed, deflecting, operative liquid
Lubricating oil 4 is separated under gravity and effect of inertia from mixed gas, and flows to one-level oil return opening 112 or air inlet 111.Together
Reason, mixed gas occurs second in the bottom surface of bottom plate 110 and collided.Unlike, mixed gas is flowed to by the second shaft orientation flowing channel 220
During 3rd shaft orientation flowing channel 220, now, impingement area is the upper surface of bottom plate 110, un-grooved feature, so mixed gas speed
Direction is mutated faster, but also exacerbates gas confusion degree.Analyzed more than, mixed gas often flows to next shaft orientation flowing channel
Before 220, will occur said process, realize that one-level is separated.
The unsegregated lubricating oil in part initially enters the second-order separation section with refrigerant gas.Mixed gas flows through two grades of mistakes
Filter runner, during the second gas-liquid filter net 330, by flutterring under collection effect for wire, make the fusion of oil droplet collection big, and then from mixed
Close and separated in gas, the fluid oil drop separated under gravity, finally goes to one-level oil return opening 112 and three-level is returned
Hydraulic fluid port 113, so far completes the second-order separation.
The mixed gas for carrying a small amount of lubricating oil initially enters central axial runner, then begins to enter three-level segregation section,
Now by being radially changed to axial direction velocity variations occur again for mixed gas velocity attitude.Carry the mixed gas of a small amount of lubricating oil
The 3rd gas-liquid filter net 430 is flowed through, collection effect is flutterred again by wire, lubricating oil separation is come out.The liquid separated
State lubricating oil 4 finally goes to three-level oil return opening 113, and refrigerant gas 3 then flows to gas outlet 122 after separating.So far three are completed
Level separation.
Further, since there is rigging error, it is impossible to avoid ground, always there is fit-up gap -- outer support circle 310 and annular
The fit-up gap of pressing plate 410, the fit-up gap of the gas-liquid filter net 430 of outer support circle 310 and the 3rd, outer support circle 310 and second
Fit-up gap of gas-liquid filter net 330 etc..So a small amount of mixed gas is from initially entering after the second-order separation section, it is along assembly building
What clearance flow was moved.Mixed gas 2 from fit-up gap spilling eventually arrives at annular oil resistance groove 121 without gas-liquid filter net.Kinetic energy
Big mixed gas collides with annular oil resistance groove 121, reaches collision separating effect, isolates liquid lubricant；And kinetic energy
Small mixed gas is then gathered in the groove of annular oil resistance groove 121, annular oil resistance groove 121 is added for lift angle structure, in groove
Lubricating oil gas more it is poly- more after, formed liquid lubricant.Liquid lubricant 4 returns to oil eventually through three-level oil return opening 113
Case.
By four times above-mentioned separation processes, effectively realize the separation of lubricating oil, reclaim.And oil separating device is machinery
Structure, stabilised efficiency, functional reliability are high.
Embodiment described above only expresses the several embodiments of the present invention, and it describes more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
