Air filter assembly

Abstract

The invention discloses an air filter assembly, which structurally comprises a shell, a blade ring, a filter cartridge and a pull rod, wherein a stop cover is arranged on one end in an axial direction of the shell, a sealing cover is arranged on the other end in the axial direction, the stop cover is provided with an exit pipe coaxial to the shell, and the pull rod is arranged in the exit pipe through a support; the filter cartridge externally sleeved with the blade ring penetrates through the other end in the axial direction of the shell, the penetration end of the pull rod is arranged in the shell, the blade ring is arranged on one side in the axial direction in the shell, the flange of the blade ring is in contact with a retainer ring of the filter cartridge, the pull rod is screwed with a nut of the sealing ring in contact with the filter cartridge, so that the sealing ring of the filter cartridge is in tight contact with the inner wall of the stop cover, and an intake pipe is arranged on a place on one side in the axial direction of the circumferential sidewall of the shell, which corresponds to the blade ring; the sealing cover penetrates through the penetration end of the pull rod, and the pull rod is screwed with a nut in contact with the sealing cover, so that the sealing cover is connected with the other end in the axial direction of the shell, and the sealing cover is provided with a dust removal bag; and the dust removal bag is communicated with a dust collector. The air filter assembly has the advantages of better filtering performance, stronger reliability, and capability of avoiding early abrasion of a locomotive engine to a certain degree.

Description

technical field [0001] The invention relates to an air cleaner assembly. Background technique [0002] At present, early wear and tear (referred to as early wear) of motor vehicle engines used in domestic vehicles is very common, and engine factories pay a considerable amount of compensation due to early wear of engines every year. The early wear of the motor vehicle engine is mainly due to the poor filtration performance of the air filter assembly fitted on it. When the road condition is not good and the motor vehicle is bumped and the engine is vibrating, the dirty air directly enters the engine. due to. [0003] The structure of the existing air filter assembly assembled on the motor vehicle engine is: it includes a casing, a blade ring, a filter element, a pull rod, and the axial end of the casing has a cover, and the axial other end has a cover, and the cover There is an air outlet pipe coaxial with the shell, and the inside of the air outlet pipe is provided with a p...

AI Technical Summary

Problems solved by technology

[0007] Due to the deficiencies in the structural design of the air filter assembly, during use, the dust accumulated in the dust discharge bag cannot be discharged as it arrives, and the timeliness of dust discharge is poor. In this way, the dust in the dust discharge bag Dust is easy to flow back and adhere to the filter paper, blocking the filter paper, so that the air filter assembly has poor filtering performance and poor reliability, which is easy to cause early wear and tear on the motor vehicle engine
