Description
Technical field
The utility model relates to engine arts, in particular to a kind of oil gas with zigzag oil return baffle
Separator.
Background technique
Gs-oil separator connects at breathing of engine mouth, because the gas blowby and machine oil of cylinder steam when engine operation
Vapour can generate pressure, will cause damage to engine, it is therefore desirable to so that it is generated vacuum by crankcase vent valve, due to logical
There are a large amount of machine oil steam in the gas that air-valve is released, so machine oil steam is mainly separated into machine oil and steaming by gs-oil separator
Vapour flows back to machine oil after bottom case is assembled inside engine and re-uses, and steam flow to engine and rekindles, prevent directly into
Enter atmosphere, cause atmosphere pollution, gs-oil separator is broadly divided into two kinds at present, labyrinthine separator and spiral vortex type separator.
And the common oil return baffle majority of labyrinthine separator is the structure of surfacing at present, can only play letter to mist of oil
Single barrier effect, separative efficiency are general.
Application No. is 201410703045.5 domestic patents of invention to disclose a kind of gs-oil separator, including is mounted on gas
Shell, setting on the cover of door room in the intracorporal S-shaped mixed gas passage of shell, setting in the intracorporal labyrinth structure of shell and cyclone structure,
Be characterized in that: the gaseous mixture entrance of the mixed-gas channel is located at the bottom of shell one end, and gaseous mixture entrance is equipped with
Block machine structure, for labyrinth structure between gaseous mixture entrance and mixed gas passage, cyclone structure is located at the end of mixed gas passage,
Mixed gas passage bottom and cyclone structure bottom are equipped with oil return control valve, the exhaust end of cyclone structure be respectively equipped with check valve and
Pcv valve.Block machine structure is equipped in this structure, this block machine body structure surface is smooth, simple barrier effect can only be played to mist of oil, point
It is general from efficiency, and this structure is complicated, easily cause failure, and higher cost, be unfavorable for for enterprise save cost.
Application No. is 201310474199.7 domestic patents of invention to disclose a kind of gs-oil separator, including is tightly connected
It is equipped on the connecting end surface of oil separator case on crankcase, oil separator case and crankcase and oil droplet is kept off into Hui Qu
Gas mixture is formed in the oil baffle of axle box, the edge of oil baffle and the connecting end surface of oil separator case between to enter
Channel, oil separator case include integrally formed Oil-gas Separation section and the fillter section for tilting upward setting, Oil-gas Separation section
Bottom surface be gradually obliquely installed upwards outward from the connecting portion of crankcase, the inner cavity of Oil-gas Separation section is filter chamber, mistake
The inner wall of filter chamber be equipped with to filter chamber convexity into and drive gas mixture in filter chamber at least one piece of curve negotiating every
Plate, fillter section are provided with filter core, and the up extension end portion of fillter section is equipped with upper capping, exhaust pipe is housed in upper capping.It is set in this structure
There is block machine structure, this block machine body structure surface is smooth, and Oil-gas Separation rate is low.
Application No. is 201510514931.8 domestic patents of invention to disclose a kind of Oil-gas Separation tooling, plane oil return gear
Plate is evenly distributed in the vertical inner wall of the external shell two sides in a manner of cross-distribution, the plane oil return baffle
One end is fixedly connected with the vertical inner wall of the external shell；Mist of oil enters Oil-gas Separation from air inlet after engine discharge
Tooling moves ahead according to the maze path being made of plane oil return baffle, and during traveling, mist of oil impinges upon plane oil return gear
On plate, oil droplet is gradually accumulated, under gravity, oil droplet is deposited on tube wall and assembles in reflux line, flows back to oil
Bottom case.
Mist of oil impinges upon on plane oil return baffle, gradually accumulates oil droplet, and plane shuttering panels and mist of oil contact area are small, collect
Oil droplet ability is poor.
Utility model content
In view of the deficiency of the prior art, it is simple to provide a kind of structure for the utility model, improves mist of oil and oil return is kept off
Plate contact area improves the gas and oil separating plant with zigzag oil return baffle of oil gas separation.
Technical solution adopted in the utility model is:
A kind of gas and oil separating plant with zigzag oil return baffle, including external shell, oil return baffle, the external shell
Internal portion is equipped with Oil-gas Separation chamber, and the external shell upper end is provided with gas vent and connects exhaust pipe, the external shell
Lower end is provided with air inlet and connects reflux line, the oil return baffle at least there are two, the oil return baffle is with cross-distribution
Mode is evenly distributed in the vertical inner wall of the external shell two sides, one end of the oil return baffle and the external shell
Vertical inner wall be fixedly connected, between the other side vertical inner wall of the other end of oil return baffle and the external shell there are cross gas
Channel, the oil return baffle indention；It is the reeded end face of setting, zigzag oil return gear with vertical inner wall fixed connection end
