The desert air-strainer that is used for light truck
The utility model relates to the desert air-strainer that is used for light truck.
In China's part desert area, as Takla Makan Desert area, there is surface dust band weather, dry throughout the year, the dust storm of large particle in the air (diameter＞10 μ m) is many, and (diameter 1～10 μ m) is also many for tiny dust granule.At present, domestic light-duty loading common empty filter commonly used is difficult to satisfy this special physical environment of surface dust band, and empty filter filter core is short maintenance period, and cost is big, and maintenance very easily causes engine cylinder-body early to grind phenomenon accidentally.
Summary of the invention
In order to solve the use problem that the empty filter of general-utility car is difficult to satisfy this special physical environment of surface dust band, the utility model provides a kind of desert air-strainer that is used for light truck.
The technical solution that realizes above-mentioned purpose is such:
The desert air-strainer that is used for light truck comprises cylindric fine cleaner housing, coaxial safe filter core and the main filter core of being provided with in the fine cleaner housing, and a fine cleaner housing radially side is provided with suction port, and its axial side is provided with the air outlet.
Described fine cleaner shell air inlet place is connecting the strainer housing, the strainer housing is a cylindrical tube shape, the one end is connecting the fine cleaner housing, the other end is the air inlet mouth of pipe, axially be laid with the whirl cylinder more than three in it, the coaxial stationary axle that is provided with in each whirl cylinder is laid with two groups of above spinning disks on the stationary axle, every group of spinning disk is made up of 6 uniform swirl vanes.
Strainer housing one side adjacent with the fine cleaner housing is provided with dust-exhausting bag.
The interior coaxial honeycomb duct that is provided with bell mouth shape of each whirl cylinder port that suction port described and the fine cleaner housing is adjacent.
The described strainer housing adjacent with the fine cleaner housing is provided with dust flue, connecting dust-exhausting bag on the port of dust flue.
Described fine cleaner diameter of the housing is 288 millimeters; Described strainer diameter of the housing is 205 millimeters, and the strainer shell length is 200 millimeters; Axially be laid with 19 whirl cylinders in the strainer housing; Every whirl cylinder diameter is 40 millimeters, and length is 140 millimeters; Stationary axle in the whirl cylinder is provided with 4 groups of spinning disks.
Described swirl vane is the spiral arcuation.
After the utility model adopts the double-stage filtering of rotary flow type strainer and the combination of papery filter paper type fine cleaner, filter efficiency can significantly be promoted, especially the clean level of surface dust band weather engine charge is had and improve effect preferably, filtering efficiency brings up to 98.95%.Practical effect and indoor current stabilization experimental result see the following form.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the local diagrammatic sketch that amplifies of the B portion of Fig. 1,
Fig. 3 be the A-A of Fig. 1 to sectional view,
Fig. 4 is that the C of Fig. 1 is to partial sectional view.
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, be used for the desert air-strainer of light truck, comprise cylindric fine cleaner housing 1, the fine cleaner diameter of the housing is 288 millimeters; Coaxial safe filter core 2 and the main filter core 3 of being provided with in the fine cleaner housing 1, fine cleaner housing 1 a radially side is provided with suction port, and its axial side is provided with air outlet 4; Fine cleaner shell air inlet place is connecting strainer housing 5, and strainer housing 5 is a cylindrical tube shape, and its diameter is 205 millimeters, and length is 200 millimeters.The strainer housing the other end is the air inlet mouth of pipe 6, the axial uniform nineteen whirl cylinder 7 that is equipped with in it, and every whirl cylinder 7 diameters are 40 millimeters, length is 140 millimeters; Be coaxially installed with stationary axle 8 in each whirl cylinder 7, uniform on the stationary axle 8 four groups of spinning disks be installed, every group of spinning disk is made up of six swirl vanes, and swirl vane 9 is the spiral arcuation; Be coaxially installed with the honeycomb duct 10 and the plane baffle plate 11 of bell mouth shape in each whirl cylinder 7 port adjacent with the fine cleaner shell air inlet.Strainer housing 5 one sides adjacent with fine cleaner housing 1 are provided with dust flue, are connecting dust-exhausting bag 12 on the port of dust flue.
Working principle of the present utility model is, owing to the leading role of swirl vane, air-flow forms eddy flow to gas by strainer the time, and the impurity in the gas is because centrifugal action is thrown to cyclone tube circumference outer ring, be deposited on the baffle plate 11 by action of gravity, discharge empty filter by dust-exhausting bag 12.
Because strainer adopts the arrangement of nineteen whirl cylinder, four groups of eddy flow chips, has strengthened cyclone filter efficient greatly.The particle of diameter in the air＞10 μ m and 80% above 1～10 μ m can be filtered out by above-mentioned rotational flow separation effect.
Gas cleaner behind the cyclone filter enters into fine cleaner by honeycomb duct 10, and the paper filter element by fine cleaner refilters the following smaller particles of diameter 10 μ m of remainder.
Behind the strainer and fine cleaner double-stage filtering by T type structural configuration, filter efficiency can significantly be promoted, and especially the clean level of surface dust band weather engine charge is had and improves effect preferably.
