Summary of the invention
For addressing the above problem, the utility model proposes a kind of oil mist filter, comprise outer cover, be arranged at filtration stay pipe, screen cover, metal screen cloth in outer cover; Wherein, described outer cover bottom and top are equipped with opening, filter stay pipe one end and stretch out outer cover bottom opening as mist of oil entrance, and described filtration stay pipe body is offered ventilation part, outer setting screen cover, fills metal screen cloth between screen cover and filtration stay pipe body.
Oil mist filter as claimed in claim 1, is characterized in that, described filtration stay pipe comprises the first pipe joint and the second pipe joint, and outer cover bottom opening is stretched out in described first pipe joint one end, and the other end is connected with second pipe joint one end.
Further, the body of described the first pipe joint and the second pipe joint all offers ventilation part, and body all arranges a screen cover outward, between screen cover and filtration stay pipe body, fills metal screen cloth.
Further, the body of described the first pipe joint and the second pipe joint all offers two pairs of relative ventilation parts, and body all arranges a screen cover outward, between screen cover and filtration stay pipe body, fills metal screen cloth.
The diameter of the screen cover that further, described the first pipe joint and/or the second pipe joint are corresponding dwindles gradually along mist of oil flow direction.
Further, also comprise mist of oil Choked flow cover, described mist of oil Choked flow cover is arranged on the outside of the screen cover that the second pipe joint is corresponding.
The beneficial effects of the utility model:
1. simple in structure, compact, reasonable in design, simple and convenient is installed.
2. the contact area of mist of oil and metal screen cloth, screen cover is larger, and double filtration is set, and can effectively promote the thorough separation of oil, gas.
3. spill port is set, makes the vacuum oil filtering flow back in vavuum pump and recycle smoothly, avoid mist of oil to discharge.
Accompanying drawing explanation
Fig. 1 is the utility model profile.
Fig. 2 is internal structural map of the present utility model.
1. outer covers in figure, 2. filter stay pipe, 3 screen covers, 4. metal screen cloth, 5. mist of oil Choked flow cover, 6. spill port, 7. nut, 8. bolt.
The specific embodiment
Below the utility model structure is elaborated.
As shown in Figure 1, the utility model is mainly made up of outer cover 1, filtration stay pipe 2, screen cover 3, metal screen cloth 4, mist of oil Choked flow cover 5.
Cylindrical or the rectangular enclosure of described outer cover 1, is preferably circle.Its bottom is provided with entrance, and top is provided with outstanding outlet.
Described filtration stay pipe 2 is a long tube (cross section is preferably circle), be placed in the cavity of outer cover 1, two joints of described filtration stay pipe 2 for connecting, the entrance of outer cover 1 bottom is stretched out in one end of the first pipe joint, as the arrival end of mist of oil, the other end is connected by flange with one end of the second pipe joint, and the other end of described the second pipe joint is aimed at the outlet of outer cover 1, as the port of export of mist of oil.Described the first pipe joint, the second pipe joint are provided with two pairs of ventilation parts that are oppositely arranged.Every joint pipeline external is provided with separately a screen cover 3 that is plugged with metal screen cloth 4, is illustrated in figure 2 internal structural map of the present utility model, can see, described screen cover 3 is along airflow direction, and diameter dwindles gradually.Outside the screen cover 3 of the second pipe joint, be also provided with a mist of oil Choked flow cover 5, the diameter of described mist of oil Choked flow cover 5 diminishes along airflow direction diameter, the screen cover 3 of its madial wall and parcel has certain distance, and top is fixed on the flange of the second pipe joint by nut 7, bolt 8.
Be provided with four oil plant spill ports 6 at filtration stay pipe 2 with outer cover 1 bottom joining place, made filtered vacuum oil flow back in vavuum pump and recycle smoothly, avoided mist of oil to discharge.
Operation principle of the present utility model is:
Oil mist filter is under the effect of motive force, the gas mixture that is positioned at porch enters from the arrival end that filters stay pipe 2, through four ventilation parts of the first pipe joint, stopped by the metal screen cloth 4 in first screen cover 3, oil is held back, and the gas mixture not stopped by the metal screen cloth 4 of the first pipe joint after the second pipe joint, is stopped by the metal screen cloth 4 in second screen cover 3 again, oil is held back, thereby realized the separation process of gas and vacuum oil.The oil being filtered, at self-acting, drops on outer cover 1 base plate of filter, and is flowed back in vavuum pump and recycled by spill port 6, discharge be without oily waste gas, and reach pollution-free, clean effect.
The beneficial effects of the utility model:
1. simple in structure, compact, reasonable in design, simple and convenient is installed.
2. the contact area of mist of oil and metal screen cloth 4, screen cover 3 is larger, and double filtration is set, and can effectively promote the thorough separation of oil, gas.
3. spill port 6 is set, makes the vacuum oil filtering flow back in vavuum pump and recycle smoothly, avoid mist of oil to discharge.
