Abstract
The utility model discloses the efficient coarse filtration air-strainer of a kind of blade ring type, it is characterized in that, upper cover and lower cover is respectively equipped with 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, and tubular one-level filter core is located at the inside of tubular shell, is 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 utility model 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.
Description
Technical field
The utility model belongs to a kind of air-strainer on automobile air inlet system, particularly relates 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 purpose of this utility model is to provide a kind of blade ring type air-strainer with higher coarse filtration efficiency.
To achieve these goals, the utility model 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 utility model 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 utility model is described in further detail by reference to the accompanying drawings.
This use of Fig. 1 new structure assembly schematic diagram
In figure: 1, tubular shell, 2, upper cover, 3, lower cover, 4, suction port, 5, air outlet, 6, tubular one-level filter core, 7, column secondary filter core, 8, back-up ring, 9, blade ring, 10, dust-exhausting bag.
Embodiment
As shown in Figure 1, the utility model 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 utility model 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.
