The upper shell 11 is internally provided with a plurality of special-shaped oil baffle plates 22 in the area close to the oil gas inlet 9 at the middle cam, the plurality of special-shaped oil baffle plates 22 form an oil baffle labyrinth in the oil-gas separation space, the oil baffle labyrinth is mainly used for filtering and collecting larger particle oil drops in the oil-gas mixture, and the diameters of the oil drops are generally more than 1 mu m;
The valve chamber cover body 1 is internally provided with a first oil discharge pipeline 23, a second oil discharge pipeline 24, a third oil discharge pipeline 25 and a fourth oil discharge pipeline 26 in sequence from an oil gas inlet 9 at the middle cam to the filter element fixing seat 3, the area, close to the first guide plate 15, of the installation port 2 is internally provided with an oil gas channel 4, the oil gas channel 4 is communicated with the interior of the filter element 14, and a first oil collecting port 8, a second oil collecting port 28, a third oil collecting port 29 and a fourth oil collecting port 30 are respectively communicated with the first oil discharge pipeline 23, the second oil discharge pipeline 24, the third oil discharge pipeline 25 and the fourth oil discharge pipeline 26.

In one embodiment of the utility model, the oil-gas mixture enters the upper shell 11 through the oil-gas inlet 9 at the middle cam, and the oil-gas mixture can quickly enter the oil-blocking labyrinth under the guide of the guide slope 27, at this time, large oil drops in the oil-gas mixture are impacted on the surface of the special-shaped oil baffle 22 under the driving of the blow-by gas flow, and the large oil drops attached to the surface of the special-shaped oil baffle 22 can flow to the first oil collecting port 8 under the action of gravity, so that the captured part of gasoline can be recovered into the crankcase through the first oil drain pipeline 23 communicated with the first oil collecting port 8;
It can be understood that, because the special-shaped oil baffle 22 forming the oil baffle labyrinth has a special curve shape, the flow of the oil-gas mixture in the labyrinth is blocked, and the oil-gas mixture also forms a backflow vortex when passing through the tortuous place arranged on the special-shaped oil baffle 22, so that larger particle oil drops in the oil-gas mixture can be more fully contacted with the surface of the special-shaped oil baffle 22, and the collection efficiency of the oil-gas mixture is improved;
Through the design of the baffle labyrinth, the oil-gas mixture entering the upper shell 3 can be subjected to oil-gas 'pre-separation' treatment, and oil drops with the diameter of more than 1 mu m are mainly separated.
It will be appreciated by those skilled in the art that while larger particles of oil droplets having a diameter of 1 μm or more can be effectively separated by using an oil baffle labyrinth comprising a plurality of profiled oil baffle plates 22, the separation effect is very limited for oil droplets having a diameter of 0.5-1 μm, and for this reason, in the prior art, oil droplets having a diameter of 0.5-1 μm in an oil-gas mixture are usually effectively separated and collected by using a filter plug made of an oleophobic fine fiber material.
However, in the process of separating oil drops with diameters of 0.5-1 μm by adopting a filter cotton filtering mode, the technical personnel find that although the oil drops with diameters of 0.5-1 μm in an oil-gas mixture can be separated efficiently by adopting the filtering mode, the pressure loss (pressure drop) before and after the filter cotton is difficult to accurately control, the separation efficiency is insufficient due to the too small pressure loss, the whole pressure loss is too large due to the too large pressure loss, the internal pressure of a crankcase is too high, and further the conditions of engine oil leakage, abnormal abrasion of parts and serious possibility of oil injection are caused.
Aiming at the technical problems, the technical personnel decides to make the following improvement on the basis of the pre-separation structure, namely, a second pore plate 7 is arranged at the position, close to a first oil collecting port 8, inside a mounting port 2, an oil collecting baffle 18 is arranged at the position, close to the second pore plate 7, inside an upper shell 11, of the upper shell 11, a plurality of strip-shaped grooves are formed in the surface of the oil collecting baffle 18, and a filter cotton assembly 5 is arranged at the position, close to a second oil collecting port 28, inside the mounting port 2;
The filter plug assembly 5 includes:
The inside of the mounting port 2 is connected with a first pore plate 56, the side surface of the first pore plate 56 far away from the second pore plate 7 is provided with a filter cotton block containing seat 55, and the side surface of the filter cotton block containing seat 55 is detachably connected with a movable panel 51;
A porous filter material made of a special oleophobic fine fiber material is arranged between the movable panel 51 and the filter block accommodating seat 55, and the filter block 52 is made of the filter block 52.
In the above technical solution, after the oil-gas mixture is subjected to the oil-gas "pre-separation" treatment of the oil-blocking labyrinth, the oil-gas mixture reaches the second orifice plate 7 under the gathering guiding action of the two arc-shaped guide blocks 21, at this time, the oil-gas mixture contacts with the surface of the second orifice plate 7, and when passing through the holes on the second orifice plate 7, the oil-gas mixture is accelerated to impinge on the oil-collecting baffle 18, then contacts with the filter cotton assembly 5 under the guiding action of the second guide plate 19, and is subjected to the oil-gas separation treatment again by the filter cotton blocks 52 in the filter cotton assembly 5, wherein the oil-gas separation process is the "coarse separation" treatment process of the oil-gas mixture;
After many experiments and observations on the basis of the above structure, the technical personnel find that by arranging the second pore plate 7 and the oil collecting baffle 18 between the baffle labyrinth and the filter cotton assembly 5, the pressure loss of the oil-gas mixture before and after passing through the filter cotton block 52 can be controlled to be about 400pa, and when the oil-gas mixture is in the pressure loss state, oil drops with the diameter of 0.5-1 μm in the oil-gas mixture can be sufficiently and efficiently filtered by the filter cotton block 52, and the problem that the pressure loss of the whole system is increased, and the internal pressure of a crankcase is possibly caused to be too high can be avoided.
Through the technical scheme, when oil drops with the diameter of 0.5-1 mu m in the oil-gas mixture are separated, the pressure loss of the oil-gas mixture before and after passing through the filter cotton can be reasonably controlled, so that the oil drops with the diameter of 0.5-1 mu m in the oil-gas mixture can be sufficiently and efficiently filtered by the filter cotton block 52, the problem that the pressure loss of the whole system is increased and the internal pressure of a crankcase is possibly caused is solved, and the oil-gas separation efficiency of the valve chamber cover with the oil-gas separation function is improved.
