Abstract
The invention discloses a blade ring type efficient coarse-filtration air filter which is characterized in that an upper cover and a lower cover are respectively arranged on the upper end and the lower end of a cylindrical shell; an air inlet is located at one side of the cylindrical shell; an air outlet is located at the middle position of the upper cover; a first-level cylindrical filtering core is arranged inside the cylindrical shell; a second-level columnar filtering core is arranged inside the first-level cylindrical filtering core; a check ring is arranged at the inner side of the inner wall of the cylindrical shell; a blade ring is arranged between the lower part of the check ring and the inner wall of the cylindrical shell. Through the arrangement above, local air turbulent flow is avoided, coarse filtration efficiency of the air filter is improved, the maintaining period of the filtering cores are prolonged, the service life of the filtering cores are increased, and the using and maintaining costs are reduced.
Description
Technical field
The invention belongs to a kind of air-strainer on automobile air inlet system, particularly relate to a kind of blade ring type air-strainer with higher coarse filtration efficiency.
Background technique
At present, automobile air inlet system air filter often selects blade ring type air-strainer, due to little by air-strainer entrucking space and that automobile air inlet system resistance is low restriction, air filtering device structure often designs unreasonable, there is local turbulent in air-strainer interior flow field, air filter coarse filtration efficiency can be caused low, affect the strainability of automobile air inlet system.
Summary of the invention
The object of the present invention is to provide a kind of blade ring type air-strainer with higher coarse filtration efficiency.
To achieve these goals, the present invention is respectively equipped with upper cover and lower cover in the top and bottom of tubular shell, suction port is located at the side of tubular shell, air outlet is located at the intermediate portion of upper cover, tubular one-level filter core is located at the inside of tubular shell, be provided with column secondary filter core in the inside of tubular one-level filter core, back-up ring is located at the inner wall of tubular shell, between the bottom and the inwall of tubular shell of back-up ring, be provided with blade ring.
By above setting, the present invention avoids air local turbulent, improves air filter coarse filtration efficiency, and filter core increases maintenance period, and filter core increases working life, reduces application maintenance cost.
Accompanying drawing explanation
Now the invention will be further described by reference to the accompanying drawings.

Embodiment
As shown in Figure 1, the present invention is respectively equipped with upper cover 2 and lower cover 3 in the top and bottom of tubular shell 1, suction port 4 is located at the side of tubular shell 1, air outlet 5 is located at the intermediate portion of upper cover 2, tubular one-level filter core 6 is located at the inside of tubular shell 1, be provided with column secondary filter core 7 in the inside of tubular one-level filter core 6, back-up ring 8 is located at the inner wall of tubular shell 1, is provided with blade ring 9 between the bottom of back-up ring 8 and the inwall of tubular shell 1.By above setting, the air filtering of the present invention on automobile air inlet system, the air being mingled with dust enters from suction port 4, under the barrier effect of back-up ring 8, blade ring 9 of passing through under air enters, such air can not enter in upper cover 2 and form local turbulent, is conducive to the coarse filtration efficiency improving air filter.When air is through blade ring 9, filter under the vane cyclone effect on blade ring 9, the dust be filtered out enters in lower cover 3, discharges through dust-exhausting bag 10.Meanwhile, the air be filtered carries out second time through tubular one-level filter core 6 and filters, then after entering the filtration of column secondary filter core 7, enters motor car engine inside from air outlet 5.
