Problems solved by technology
There are deficiencies: one is that the air to be filtered has a large filtering resistance after reciprocating three times, which reduces the output power of the engine; the other is that the air to be filtered enters the filtered oil on the bottom side from the single row of air inlet pipes on the side of the air inlet shell In the process, the foggy air or foam formed by the uneven impact of the air entering the oil surface will block the steel mesh filter element or damage the paper filter element prematurely, which will affect the air filtration quality. Operators need to Frequent disassembly and maintenance of steel wire mesh filter elements or replacement of paper filter elements increases the cost of use

Embodiment Construction
[0016] figure 1- Figure 10 shown. This heavy-duty automobile oil-bath type powerful cyclone air filter mainly includes a circular filter body and a rectangular air inlet casing connected to it, a cyclone pipe, and a filter oil 6 placed at the bottom of the air inlet casing; In the inner cavity of the air inlet housing located below the air inlet pipe 1, a deflector 2 is provided with a ring sleeve connected to the outer circular surface of the lower end of the cyclone pipe; the support provided in the inner hole of the lower end of the cyclone pipe On the frame 3, a sealed dust-proof bearing is provided to rotate and connect with the rotating fan blade 4; under the rotating fan blade, the reverse swirl disk 5 cyclone sleeve fixedly connected to the air inlet housing is ringed on the rotating fan blade 4. On the outer circle; the cyclone opening 12 provided on the inner end face of the cyclone sleeve through hole of the reverse swirling disk 5 is opposite to the opening direc...

The invention discloses a heavy-duty car oil-bath power rotational flow air filter. The technical scheme is mainly that a guide plate (2) which is arranged in the inner cavity of an air inlet housing positioned under an air inlet pipe (1) is connected to the external surface of the lower end of a tornadotron in a circular sheath way; a rotational fan blade (4) is rotationally connected to a bearing frame (3) arranged in the inner hole of the lower end of the tornadotron; under the rotational fan blade, a retrorse rotational flow disk (5) cyclone sleeve pipe which is fixedly connected to the air intake housing is circularly sheathed on the excircle of the rotational fan blade; and the bottom of the air intake housing under the retrorse rotational flow disk is provided with filtering oil (6). Cyclone openings of which the openings directions are relatively opposite are respectively arranged on the guide plate, the rotational fan blade and the retrorse rotational flow disk, thereby forming power air rotational flows with low resistance. The air filter obviously reduces the resistance of air filtration, effectively increases the output power of an engine and improves the air filtration quality, eliminates the phenomenon of early blockage or damage of a paper filter element, prolongs the service life of the paper filter element and reduces the use cost.
Description
(1) Technical field: [0001] The invention relates to an automobile air filter device; in particular, it relates to an oil-bath type powerful cyclone air filter for a heavy-duty automobile. (two) background technology: [0002] The heavy-duty automobile oil-bath air filter in the prior art has a structure mainly in which a steel wire mesh filter element is connected in the inner chamber of the air inlet housing connected with the filter body; With filter oil. During operation, the air to be filtered that contains dust impurities and / or rain and snow drops enters the single-row air intake pipe on the inner side of the air intake shell, and after being coarsely filtered by the filter oil bath, it enters the steel mesh filter element for a second time for filtration, and finally passes through the filter. The paper filter element in the cleaner body is filtered for the third time before it can enter the engine to work. There are deficiencies: one is that the air to be filtered...
