Embodiment Construction

[0009] Such as figure 1 Shown, the present invention is provided with air inlet 6 on housing 1, and housing 1 bottom is provided with dust discharge pipe 2, prefilter bottom surface 4 and air outlet 3, and the inner side of air inlet 6 is provided with blade ring 5.

[0010] The air entering the pre-filter from the air inlet 6, when passing through the blade ring 5, due to the swirling effect of the blade ring 5, the air performs a spiral motion in the housing 1, and the component of its motion speed in the circumferential direction forms a centrifugal force, which will The large particles in the dust entering the pre-filter are thrown onto the inner wall of the housing 1 and move spirally towards the bottom surface 4 of the pre-filter along the inner wall of the housing 1 under the action of the airflow. The connection with the shell 1 makes a circular motion, and is removed from the pre-filter in the dust discharge pipe 2, thereby realizing coarse filtration. Since the blade...

Abstract

The invention discloses an automobile high prefilter, which is characterized in that: the shell has an air inlet; the lower part of the shell is provided with a dust discharge pipe, a prefilter bottom face and an air outlet; and a vane ring is arranged on the inner side of the air inlet. The automobile high prefilter makes full use of the characteristics of low resistance and high efficiency of the direct swirl vane ring, realizes higher pre-filtering effect with smaller resistance loss and obtains a good effect in the actual use in loading.

Description

technical field [0001] The invention belongs to a pre-filter of an automobile air intake system, in particular to a pre-filter which uses a straight-through swirl vane ring to separate water and dust in an air intake system through the action of centrifugal force. Background technique [0002] At present, the existing air filter pre-filter mainly adopts the method of adding a swirl tube pre-filter to the high-level pipe. The air entering the high-level tube rotates in the swirl tube to generate centrifugal force, and large particles of dust are thrown to the wall of the swirl tube. , and discharged through the dust outlet. The disadvantage of this prefilter is high resistance and takes up a lot of space. Contents of the invention [0003] The purpose of the present invention is to provide a high-position pre-filter suitable for medium-sized automobiles with small space occupation and low resistance. [0004] The technical solution of the present invention is: an air inle...
