Problems solved by technology

In areas with strong wind and sand or sand blowing weather, the air mixed with a large amount of gravel or dust is first filtered by a centrifugal air filter and then filtered by a dry air filter. After passing through these two stages of filtration, the dust or gravel in the air is separated, It makes the air entering the engine relatively pure, reduces the wear inside the engine, and prolongs the life of the engine; however, the first-stage filtration efficiency of the traditional centrifugal air filter is low, and when the air filtered by the centrifugal air filter reaches the dry air filter , the filtration burden borne by the dry air filter is relatively large, resulting in an increase in the replacement frequency of the dry air filter, an increase in the frequency of vehicle maintenance, and an increase in vehicle maintenance costs

Abstract

The invention belongs to the field of air filters, in particular to an automobile air filter, which includes cylinder A, cylinder B, cylinder C, spiral piece, swirl tube, cylinder D, collection sleeve A, collection sleeve B, pendulum block, sector Block, elastic soft film, collecting sleeve C, threaded sleeve, wherein the outer cylindrical surface of cylinder C is a stepped cylindrical surface, and the outer cylindrical surface of the large diameter part of the upper section of cylinder C and the outer cylindrical surface of the small diameter part of the lower section of cylinder C pass through The outer cone surface is transitionally connected; the air entering the cylinder C in the present invention is guided by the corresponding swirl tube to form a local spiral motion in the cylinder C again and produce centrifugal action, and the air entering the cylinder C carries small gravel or dust Sputtered to the inner cone surface of the cylinder C under the action of local centrifugal, and under the reflection of the inner cone surface, it falls obliquely downward and quickly falls into the collection sleeve A, and then completes the re-filtering of the air entering the cylinder C, thereby improving Air filtration efficiency of the whole device.

Description

technical field [0001] The invention belongs to the field of air filters, in particular to an automobile air filter. Background technique [0002] In order to improve the filtration efficiency of the air entering the engine, vehicles used in areas with large wind and sand are equipped with a device for secondary filtering of the air entering the engine. The device for secondary filtering of air is generally a centrifugal air filter Combination with dry air filter or centrifugal air filter and wet air filter; due to the low filtration efficiency of wet air filter, the combination of centrifugal air filter and wet air filter is used Less, most of them use the secondary filtration of the combination of centrifugal air filter and dry air filter. In areas with strong wind and sand or sand blowing weather, the air mixed with a large amount of gravel or dust is first filtered by a centrifugal air filter and then filtered by a dry air filter. After passing through these two stages ...
