Abstract
A two-stage desert air filter comprises a coarse filter (1) and a fine filter (2). The coarse filter (1) and the fine filter (2) are integrated into an overall structure; and an air outlet end of the coarse filter (1) is connected with an air inlet end of the fine filter (2). In the utility model, the coarse filter (1) and the fine filter (2) are integrated into an overall structure; the air filter is small in size, compact in structure and beautiful in appearance; the utility model is not only easy in installation in a car, but also has a smaller air inlet resistance and higher filtration efficiency. Tests have proved that the original resistance has been increased only by 1 to 3 percent compared with a single-stage filter; the filtration efficiency can reach 99.8 percent. Vehicle assembly tests in heavy vehicles factories have also achieved good effects.
Description
Technical field
The utility model relates to a kind of twin-stage desert air-strainer.
Background technique
With the immediate prior art of the utility model is " publication number is CN2300735Y " " the thick level of vortex type air-strainer ", this strainer is a single-stage, before being installed at the former gas handling system of automobile, be installed in series with original-pack fine cleaner, though can effectively improve filtering efficiency, make motor be difficult for taking place premature wear, also prolonged the working life of fine cleaner simultaneously in desert area.But because this strainer is to be installed on the original-pack fine cleaner and will to be installed in series by pipeline, not only volume is bigger, and intake resistance is strengthened, and has influenced the performance of motor, is mainly used in the improvement of used car gas handling system.
Summary of the invention
The technical problem that the utility model solves: designing a kind of strainer and fine cleaner is an integrally-built twin-stage desert air-strainer, makes volume-diminished, and compact structure not only be convenient to install on car body, and intake resistance is less, and filtering efficiency is higher.
Technical solution of the present utility model:
A kind of twin-stage desert air-strainer comprises strainer (1) and fine cleaner (2), and strainer (1) and fine cleaner (2) are an overall structure, and the inlet end of the outlet side of strainer (1) and fine cleaner (2) joins.
Strainer (1) is positioned at the below of fine cleaner (2), and fine filtering core (4) vertical arrangement in the relative fine cleaner (2) of the tornadotron (3) in the strainer (1).Or fine cleaner (2) is positioned at the below of strainer (1), and the outlet side of strainer (1) joins by the inlet end of air flue (5) with fine cleaner (2), and the tornadotron (3) in the strainer (1) relatively the fine filtering core (4) in the fine cleaner (2) be arranged in parallel.
Working principle: air enters strainer (1) from suction tude (6), centrifugation through tornadotron (3), sand and dust more than 93% are discharged outside the filter body from dust discharge valve (7), motor is caused the basic emptying of coarse sand dirt more than the 10 μ m of wearing and tearing, the following powdery particulate of about 7% and 10 remaining μ m enters fine cleaner (2), behind fine filtering core and safety bucket secondary filter, the air that enters motor by steam outlet pipe (8) has just cleaned very much.
The utility model is compared with prior art: because strainer and fine cleaner are an overall structure, volume is less, compact structure, and beautiful shape not only be convenient to install on car body, and intake resistance is less, and filtering efficiency is higher.Original resistance only increases 1-3% than the single-stage filter after tested, and filtering efficiency can reach 99.8%, and the entrucking test has also obtained effect preferably through heavy-duty car factory.

Embodiment
1,2 first kind of embodiment of the present utility model described in conjunction with the accompanying drawings.
A kind of twin-stage desert air-strainer comprises strainer (1) and fine cleaner (2), and strainer (1) and fine cleaner (2) are an overall structure, and the inlet end of the outlet side of strainer (1) and fine cleaner (2) joins.Strainer (1) is positioned at the below of fine cleaner (2), and fine filtering core (4) vertical arrangement in the relative fine cleaner (2) of the tornadotron (3) in the strainer (1).Wherein the structure of strainer is basic identical with " the thick level of the vortex type air-strainer " structure of " publication number is CN2300735Y ", and the fine cleaner structure on the structure of fine cleaner and the existing vehicle is basic identical.
3,4 second kind of embodiment of the present utility model described in conjunction with the accompanying drawings.
A kind of twin-stage desert air-strainer comprises strainer (1) and fine cleaner (2), and strainer (1) and fine cleaner (2) are an overall structure, and the inlet end of the outlet side of strainer (1) and fine cleaner (2) joins.Fine cleaner (2) is positioned at the below of strainer (1), and the outlet side of strainer (1) joins by the inlet end of air flue (5) with fine cleaner (2), and the fine filtering core (4) in the relative fine cleaner (2) of the tornadotron (3) in the strainer (1) is arranged in parallel.Wherein the structure of strainer is basic identical with " the thick level of the vortex type air-strainer " structure of " publication number is CN2300735Y ", and the fine cleaner structure on the structure of fine cleaner and the existing vehicle is basic identical.This embodiment in use has vertical and horizontal two kinds of structures, can select for use according to the different automobile types structure of automobile.
