Abstract
The utility model discloses a dry-wet combined multi-stage air filter which includes a shell, an air inlet arranged at the upper part of the shell, an air outlet arranged at the outside of the shell, a liquid tank arranged at the bottom of the shell inner chamber, a partition plate arranged in the liquid tank, an air passage connected with one end of the partition plate and communicated with the liquid tank, a filter screen plate arranged at the other end of the partition plate, a filter core arranged in the shell inner chamber and communicated with the air outlet at one end; wherein the upper end of the air passage is communicated with the air inlet. By employing a multi-stage filtering mode composed of liquid attaching-depositing filtration and filter core filtration, arranging the partition plate in the liquid tank and arranging the air passage and the filter screen plate on two ends of the partition plate respectively, not only the air is wholly filtered via the liquid chamber to improve filtering effect of the air filter, but also filtrate is prevented from scattering into the shell inner chamber to wet the filter core so that service life of the filter core is prolonged. The air filter is an ideal auxiliary device for a vehicle engine.
Description
Technical field
The utility model relates to a kind of motor car engine air-strainer, particularly a kind of combination multistage filtering air-strainer that wets of doing.
Background technique
Because arid is short of rain, and dust storm is bigger throughout the year, stirs up a cloud of dust, cause air to worsen in the many areas of China.The dust that Motor Vehicle is kicked up under steam is easy to suck cylinder through engine intake, thereby takes the wearing and tearing that each parts of motor have been aggravated at each position to by machine oil again.Wear medium in the motor car engine is mainly from airborne dust, and the overhead floating dust-size of road differs, and is serious to each component wear in the motor car engine.Though existing motor car engine also is provided with air-strainer, great majority are individual layer baffle types, poor filtration effect, stop up easily, the working life of filter core is short, has brought a lot of troubles and economic loss to the user, also causes a large amount of physical wastes to be unfavorable for environmental protection.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of wet combination multistage filtering air-strainer of doing, filtration effective, the long service life of filter core.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of combination multistage filtering air-strainer that wets of doing, comprise housing, housing top is provided with suction port, and hull outside is provided with the air outlet, and the housing intracavity bottom is provided with the liquid storehouse, top, described liquid storehouse is provided with dividing plate, one end of dividing plate is connected with the air flue that communicates with the liquid storehouse, and described air flue is connected with suction port, and the other end of dividing plate is equipped with screen pack, described housing inner chamber is provided with filter core, and an end of described filter core communicates with the air outlet.
The beneficial effects of the utility model are: owing to adopt liquid to adhere to the multistage filtering mode of sedimentation and filtration and filter element filtering composition, and the liquid storehouse is provided with dividing plate, air flue and screen pack are separately positioned on the dividing plate two ends, thereby not only can make air improve the filtering effect of air-strainer greatly through the filtration of liquid storehouse fully but also avoided filtrate to be splashed to the housing inner chamber and dipped in wet filter core, prolonged the working life of filter core, the vapour lock of the air-strainer of this filtration is less, can provide the air of cleaning for motor car engine, thereby reduced the wearing and tearing of motor, prolonged the working life of motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional structure schematic representation of the present utility model;
Fig. 2 be Figure 1A to the structure enlarged view;
Fig. 3 is a working principle schematic representation of the present utility model.
Embodiment
Referring to figs. 1 through Fig. 3, a kind of wet combination multistage filtering air-strainer of doing of the present utility model, comprise housing 1, housing 1 top is provided with suction port 2, housing 1 arranged outside has air outlet 3, housing 1 intracavity bottom is provided with liquid storehouse 5,5 tops, liquid storehouse are provided with dividing plate 51, one end of dividing plate 51 is connected with the air flue 4 that communicates with liquid storehouse 5, the upper end of air flue 4 is connected with suction port 2, the other end of dividing plate 51 is equipped with screen pack 6, and housing 1 inner chamber is provided with filter core, and an end of filter core communicates with air outlet 3.
In the present embodiment, filter core is that thick, the fine filtering core 8,9 of tubular combines, but also can be that flat filter core by single or multiple lift is formed by stacking.Fine filtering core 9 is arranged on the inside of coarse filter element 8, and an end of fine filtering core 9 is connected with air outlet 3, is installed with screw rod 7 between the housing 1 relative with it of air outlet 3, and thickness filter core 8,9 is fixedly installed on the screw rod 7 with nut.In the time of work, the air outlet 3 of this air-strainer is connected with the suction port of motor car engine, under the suction of engine running, air enters air flue 4 backs from the suction port 2 on housing 1 top and pours liquid storehouse 5 from the air outlet of air flue 4 lower ends, adheres to through the liquid on the screen pack 6 then and enters housing 1 inner chamber after filtering.Air passes through the filtration of coarse filter element 8 and fine filtering core 9 at last successively, enters cylinder by air outlet 3, for motor provides the air of cleaning, thereby has reduced the wearing and tearing of dust to motor, has prolonged the working life of motor.Owing to adopt liquid to adhere to the multistage filtering mode of sedimentation and filtration and filter element filtering composition, and liquid storehouse 5 is provided with dividing plate 51, air flue 4 and screen pack 6 are separately positioned on dividing plate 51 two ends, thereby not only can make air improve the filtering effect of air-strainer greatly through 5 filtrations of liquid storehouse fully but also avoided filtrate to be splashed to the housing inner chamber and dipped in wet filter core, prolonged the working life of filter core.
Choked flow net 10 is installed in liquid storehouse 5, when air pours liquid storehouse 5, can keeps liquid steady, prevent too splashing of liquid, make that the adsorption effect of the 5 pairs of dust in liquid storehouse is better.
In addition, 3 relative sides are provided with the end cap 11 of folding but housing 1 is in the air outlet, can open end cap 11 when air-strainer need be cleared up thickness filter core 8,9 is taken out cleaning, and are easy and simple to handle.
A kind of wet combination multistage filtering air-strainer of doing of the present utility model, filtration effective, the long service life of filter core is the desirable match equipment of motor car engine.
