Abstract
The utility model discloses an oil bath dry type compound air filter for a heavy-duty car, which is characterized in that an air inlet pipe is arranged on an air filter casing, the upper part of the air filter casing is provided with a dry type fine filter casing, an air outlet pipe is arranged on the dry type fine filter casing, and a paper filter core is arranged inside the dry type fine filter casing. Through the arrangement, the oil bath dry type compound air filter realizes the expected goal, can achieve the coarse filtration efficiency of over 99 percent when being used for coarse filtration efficiency test, can greatly reduce the maintenance and replacement period of the main filter core, and can achieve good using effect during real loading process.
Description
Technical field
The utility model belongs to air filter of automobile, particularly relates to a kind of air-strainer that utilizes the empty filter coarse filtration of oil bath type to have high coarse filtration efficient.
Background technique
At present, the empty filter of existing heavy-duty car has two kinds of coarse filtration patterns, a kind of is to increase blade ring in the empty filter of dry type, another kind is in the place ahead of the empty filter of dry type one cyclone tube strainer to be set, the coarse filtration efficient of blade ring is about 80%, the coarse filtration efficient of cyclone tube strainer is about 93%, and this can not satisfy coarse filtration and require for the vehicle of working down at high concentration dust environment (as mine, desert region).
Summary of the invention
The purpose of this utility model is to provide a kind of air-strainer that utilizes oil-bath filter to make strainer.
The technical solution of the utility model is: be provided with suction tude on empty filter housing, empty filter enclosure interior is provided with intake duct, machine oil, pasta air vent, lower filter screen and upper filter screen, be provided with dry type fine filtering housing on empty filter housing top, be provided with steam outlet pipe on dry type fine filtering housing, dry type fine filtering enclosure interior is provided with the papery filter core.
The empty filter of one oil bath type is set below common dry-type air cleaner, the housing of the housing of the empty filter of common dry type and the empty filter of oil bath type is connected, the air of coming in from high-order suction tude filters through the empty filter of oil bath type earlier, carries out fine filtering through the empty filter of dry type again.
By above setting, the utility model has been realized re-set target, uses this combined air filter to carry out the coarse filtration efficiency test, coarse filtration efficient reaches more than 99%, greatly reduce the maintenance replacement cycle of main filter core, in actual entrucking is used, also obtained good using effect.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described further.
Fig. 1 is the utility model structural representation.
Among the figure 1, suction tude 2, empty filter housing 3, intake duct 4, machine oil 5, empty filter lower cover 6, pasta air vent 7, lower filter screen 8, upper filter screen 9, coarse filtration fine filtering interface 10, dry type fine filtering housing 11, steam outlet pipe 12, papery filter core
Embodiment
As shown in Figure 1, the empty filter housing 2 of the utility model oil bath type, on empty filter housing 2, be provided with suction tude 1, empty filter housing 2 inside are provided with intake duct 3, machine oil 4, pasta air vent 6, lower filter screen 7 and upper filter screen 8, be provided with dry type fine filtering housing 10 on empty filter housing 2 tops, be provided with steam outlet pipe 11 on dry type fine filtering housing 10, dry type fine filtering housing 10 inside are provided with papery filter core 12.
The dust that is entered the sky filter by suction tude 1, intake duct 3 pours in the machine oil 4, the part dust is adsorbed by machine oil, the realization one-level is filtered, air enters lower filter screen 7, upper filter screen 8 along pasta air vent 6 then, because the suction-operated of filter screen realizes cascade filtration, through the papery filter core 12 of the air behind the strainer filtering in coarse filtration fine filtering interface 9 enters dry type fine filtering housing 10, finish three-stage filtration by papery filter core 12, the clean air after papery filter core 12 filters enters motor by steam outlet pipe 11.
The utility model makes full use of the empty filter of oil bath type and makees strainer, the coarse filtration efficient of sky filter is improved greatly, and laboratory coarse filtration efficient reaches more than 99%, greatly reduces the maintenance replacement cycle of main filter core, in actual entrucking is used, also obtained good using effect.
