Embodiment Construction

[0018] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings:

[0019] see figure 1 :

[0020] The assembly includes a casing 1, a blade ring 2, a filter element 3, and a pull rod 4.

[0021] The axial left end of the cylindrical shell 1 has a cover 1a, and the axial right end has a cover 1b. The cover 1a has a circular air outlet pipe 1c coaxial with the outer shell 1. The inside of the air outlet pipe 1c is provided with a bracket 1d. A pull rod 4 coaxial with the shell 1, the pull rod 4 passes through the axial right end of the shell 1 and the end of which is threaded.

[0022] The filter element 3 is composed of a filter paper 3b sandwiched between two layers of circular protection tubes 3a inside and outside, a circular sealing ring 3c respectively arranged at both axial ends of the protection tube 3a, and a circular retaining ring 3d with a sealing ring 3e. The sealing ring 3e and retaining ring 3d are ...

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...
