Description
Technical field
The utility model belongs to and is used in engineering machinery fuel oil engine fittings technical field, relates in particular to a kind of oil bath air cleaner.
Background technique
In the great engineering construction such as mine, expressway, airport, railway, water conservancy and hydropower, the large-scale power mechanical engineerings such as large-scale petrol and diesel oil car, excavator play an important role; In the rugged environment that this sudden and violent dirt flies upward, air filter consists of the umbrella for above-mentioned mechanical fuel motor.At present, the employed air filtering of above-mentioned mechanical fuel motor mechanism arranges by the two-layer configuration that uses of connecting and consists of; Wherein the structure (as shown in Figure 1) of first order oil bath type air filter structure comprises the filtration oil tray 1 that is provided with filter screen 6 and the cylindrical shell 5 that is provided with air induction mast 2 and gas outlet 3 and is provided with the tube-in-tube structure of the filter layer 4 that some layers are made of steel wire consists of; The second level consists of for the air filtering mechanism that is situated between by paper; But because the air-filtering of the oil bath type air filter structure of the formation first order is passive type, namely by the suction of fuel engine to air, so that air at first by the pasta 14 by filtering oil tray 1 behind the air induction mast with dust absorption, the air of purification is again through the filter screen 6 that filters oil tray be arranged at filter layer 4 in the cylindrical shell and filter and enter the second filtering mechanism through gas outlet 3; In the filter process of air, entering the air that filters oil tray 1 by air induction mast can only contact with its pasta, its area of contact is less, so that dust its filterability is the highest after by this filtering mechanism can reach 50%, cause the filtration burden of second level paper Jie air filtering mechanism, therefore cause greatly shorten the working life of this paper Jie air filtering mechanism, in use must constantly change.The oil bath type air filter structure of changing frequently paper Jie air filtering mechanism and low filterability not only causes the utilization rate of engineering machinery to reduce, affect project progress, if main be that paper Jie air filtering mechanism changes the working life that untimely meeting has a strong impact on the tool fuel engine.
The model utility content
The purpose of this utility model just provides a kind of rational in infrastructure, oil bath air cleaner that filtration, purification is effective.
The technological scheme that realizes the utility model above-mentioned purpose is:
A kind of oil bath air cleaner, comprise that the bottom is provided with the filtration oil tray of filter screen, being provided with the center on this filtration oil tray top is that air induction mast, sidepiece are the cylindrical shell of the tube-in-tube structure of gas outlet, is provided with the filter layer that some layers are made of steel wire in the sleeve of described cylindrical shell; Air induction mast top at described cylindrical shell is provided with electric fan mechanism.
The additional technical feature that consists of above-mentioned a kind of oil bath air cleaner also comprises:
---the diameter of described electric fan and the diameter of described cylindrical shell are complementary, and the upper cartridge of described cylindrical shell is set to funnel-shaped structure;
---be provided with the middle part in the bottom of described electric fan mechanism for filtering oil tray with second of the supporting central cylinder of described air induction mast;
---the end sealing of described central cylinder, border are provided with some filtered air inlet holes;
---the open-topped of described central cylinder also is provided with the umbrella shape cover body.
A kind of oil bath air cleaner provided by the utility model compared with prior art has the following advantages: one, owing to be provided with fan at the air induction mast place that consists of this oil bath air cleaner, therefore can strengthen and enter the pressure that filters the oil tray Air, and the filtration oil reservoir in the oil tray can be blown afloat oil bloom, thereby greatly having improved air connects with the surface of contact that filters oil reservoir, Effective Raise filter oil reservoir to the adsorption performance of dust in the air, so that the filter efficiency of koniology has reached more than 85%, not only can effectively reduce the burden of second level paper Jie filter cleaner, improve the working efficiency of machinery, main is that this oil bath air cleaner is because the effect of fan, the air suction of reduce fuel oil motor has greatly reduced the efficient that resistance of air is conducive to motor and has improved; Its two owing to be provided with again the oil tray filtering mechanism in filter cleaner air induction mast fan and filtration between oil tray, further improved the filtering effect of air, so that reached more than 98% by the filter efficiency of gas outlet air out.
