Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b):

an oil-gas separator with a filter-wad assembly, shown with reference to fig. 1 and 2, comprises a bottom shell 1, a top cover 2, and a sealing edge structure 3.

The three-dimensional structure of the bottom case 1 can be seen in fig. 4, wherein the bottom structure of the bottom case 1 can be seen in fig. 2 and 3, the bottom case 1 is substantially in a long structure, first, a first air groove 4 and an inclined groove 5 for transiting the first air groove 4 are provided at the bottom of the bottom case 1, and the configuration of the inclined groove 5 can be seen in fig. 3. Be provided with thick filtration 6 in first air duct 4, thick filtration 6 specifically is in fig. 2 and fig. 3, in the protruding interval distribution of horizontal rectangular arch above the inner wall of drain pan 1, forms rectangular recess between the rectangular arch, and oil gas can carry out the initial segregation like this, and fluid can gather at rectangular recess, then combines again "<" the lug of symbol shape filters oil gas through the baffle again, and oil gas can enter into the 5 positions of tipper this moment.

In the position of the tilting trough 5 there is a seat 9. Referring to fig. 2, 3 and 4, the bottom case 1 is formed with a second air groove 7 on the other side of the inclined groove 5, and the second air groove 7 is provided with a limit stop 8 distributed annularly and a seat 9 communicated with the inclined groove 5. An annular filter cotton 10 is clamped and fixed between the limit stop 8 and the seat body 9. The annular filter cotton 10 is in a C-shaped structure, and a three-dimensional structure is referred to in figure 4. And is assembled and embedded into an integral structure formed by a plurality of limit stops 8 in a vertical insertion mode. The outer side of the annular filter cotton 10 is clamped by a limiting block, and the inner side of the annular filter cotton is clamped by a seat body 9.

In fig. 4 it can be seen that the top of the housing 9 is provided with a catch 11, the housing 9 having an opening. The clamping column 11 is provided with an air hole 12 which is communicated up and down, the top of the seat body 9 is fixed with a shielding piece 13 through the clamping column 11, and the shielding piece 13 is provided with a punching seam 14. The shielding sheet 13 is vertically clamped into the clamping column 11, and then the part constructed by the punching slot 14 can float up and down. The punch tailor 14 is substantially "C" shaped. When the shielding piece 13 is impacted by airflow at the opening edge of the seat body 9 through the blanking seam 14, the shielding piece can elastically vibrate, oil gas can go out through the blanking seam 14, and most of oil liquid is shielded and accumulated.

The top cover 2 covers the second air groove 7 and is in sealing connection with the second air groove 7, wherein oil gas sequentially passes through the first air groove 4, the inclined groove 5, the outer side of the seat body 9 and the second air groove 7. The opening edge of the base body 9 is provided with a plurality of radial grooves 15, the radial grooves 15 are communicated to the annular filter cotton 10 through the inclined groove 5, and the tops of the radial grooves 15 are elastically shielded by the shielding sheets 13. When the air flow is large, the air flow discharge direction can be changed by directly passing through the radial grooves 15 and penetrating through the annular filter cotton 10 from another path.

The second air groove 7 is formed with a slope surface 16 through the inclined groove 5, an oil storage bottom groove 17 is arranged at the lower part of the slope surface 16, and an oil return vertical pipe 18 is arranged on the oil storage bottom groove 17. A one-way valve body 19 is arranged in the oil return vertical pipe 18. The oil-gas separation device has the advantage that oil separated from oil gas can be quickly recovered.

With continued reference to fig. 3 and 4, an assembly seat 20 is disposed in the second air groove 7, a filter element 21 is fixed on the assembly seat 20 in a snap-fit manner, the top of the filter element 21 is limited on the top cover 2, and an exhaust pipe 22 is disposed at a position on one side of the top cover 2, which is close to the filter element 21. Further improve the filter effect like this, improve filtration efficiency, have dual filterable effect.

In summary, the performance of the above structure design in the working process is described as follows: the oil gas passes through the first air groove 4, under the action of the inclined groove 5, the oil gas is transited to the space of the second air groove 7 from high to low along the groove bottom of the inclined groove 5 and then through the seat body 9, in the second air groove 7, the oil gas is filtered by the annular filter cotton 10, and the filtering contact surface of the oil gas on the space is greatly improved compared with the prior art, thereby further improving the filtering efficiency, and the filtering capacity of the annular filtering cotton 10 is improved due to the increased volume, the assembly and replacement mode is simpler and easier, the top cover 2 can be disassembled to directly take and replace, then the shielding piece 13 blocks and slows down the airflow power of the oil gas, and can accumulate and block oil drops or oil mist, so that the oil gas can contact the annular filter cotton 10 for a longer time, the oil then accumulates at the bottom of the annular filter cotton 10 and flows downwards under the action of the slope, so as to be convenient for recovery. Radial slot 15's design can reduce the vibration range that shelters from piece 13, can effectively protect and shelter from piece 13 for it is more reliable to shelter from piece 13 vibration when receiving oil gas air current to promote, shelters from 13 non-deformable transitions, can effectively independently resume, and can gather fluid and further promote fluid to flow from high to low through the vibration.

Of course, the above is only a typical example of the present invention, and besides, the present invention can also have other various specific embodiments, and all technical solutions adopting equivalent replacement or equivalent transformation are all within the scope of the present invention as claimed.
