Preferably, the first separation chamber is rectangular, a first baffle and a second baffle are obliquely arranged in the first separation chamber, and gaps for airflow to pass through are formed between the first baffle and the inner wall of the first separation chamber and between the first baffle and the inner wall of the second separation chamber.
Further preferably, the first baffle and the second baffle are respectively provided with a first stop block and a second stop block in a protruding manner.
Preferably, a first oil-gas separation box is arranged in the gap in the middle of the first separation cavity.
Preferably, a third baffle and a fourth baffle are arranged in the second separation cavity, and the third baffle and the fourth baffle are vertically arranged in the second separation cavity.
Further preferably, a second oil-gas separation box is arranged at the rear part of the second separation cavity.
Preferably, an oil return passage communicated with the oil return port is arranged at the tail end of the second separation cavity.
Further preferably, a check valve is arranged on the oil return passage.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
because the utility model discloses set up two waste gas entries in first separation chamber, waste gas striking blocks the piece at first stopper and second through first baffle and second baffle after with higher speed, can detach the oil drop in some gas in advance, can be comparatively easy after passing through subsequent oil-gas separation box with remaining oil drop separation again.
Drawings
FIG. 1 is a perspective view of an embodiment;
FIG. 2 is a schematic cross-sectional view of an oil-gas separation chamber.
In the above drawings: 1. a cover body; 2. separating the baffle plate; 3. an exhaust gas inlet; 4. an exhaust interface; 5. an oil return port; 6. a partition plate; 7. a first baffle plate; 8. a second baffle; 9. a first stopper; 10. a second stopper; 11. a first oil-gas separation cartridge; 12. a third baffle plate; 13. a fourth baffle; 14. a second oil-gas separation cartridge; 15. an oil return passage; 16. a one-way valve.
Detailed Description
The invention will be further described with reference to the embodiments shown in the drawings to which:
referring to the attached drawings 1-2, the oil-gas separation engine cover comprises a cover body 1 and a separation baffle 2 fixedly arranged at the lower part of the cover body 1, the separation baffle 2 and the cover body 1 enclose an oil-gas separation cavity, an exhaust interface 4 communicated with the oil-gas separation cavity is arranged on the cover body 1, an oil return opening 5 is formed in the separation baffle 2, a partition plate 6 is arranged in the oil-gas separation cavity, the oil-gas separation cavity is divided into a first separation cavity and a second separation cavity by the partition plate 6, a notch is formed in the middle of the first separation cavity and communicated with the second separation cavity, two exhaust gas inlets 3 are further arranged on the separation baffle 2, the two exhaust gas inlets 3 are respectively located at two end parts of the first separation cavity, and the tail end of the second separation cavity is communicated with the exhaust interface 4.
The first separation cavity is rectangular, a first baffle 7 and a second baffle 8 are obliquely arranged in the first separation cavity, and gaps for air flow to pass through are formed between the first baffle 7 and the inner wall of the first separation cavity and between the second baffle 8 and the inner wall of the first separation cavity.
The first baffle 7 and the second baffle 8 are also respectively provided with a first stop block 9 and a second stop block 10 in a protruding way.
The breach in the middle part of first separation cavity is provided with first oil-gas separation box 11, and first oil-gas separation box 11 adopts the straight strip formula oil-gas separation box in this embodiment.
And a third baffle plate 12 and a fourth baffle plate 13 are arranged in the second separation cavity, and the third baffle plate 12 and the fourth baffle plate 13 are vertically arranged in the second separation cavity.
