Description

Integrated air filter

Technical field

The utility model relates to a kind of integrated air filter, belongs to air filtering equipment.

Background technique

At present, the used air-strainer of internal-combustion engine is divided into three kinds: 1, dry-type air cleaner usually; 2, oil bath wet-type cleaner; 3, I wet in conjunction with air-strainer at doing of design.They in use have following characteristics: 1, the dry-type air cleaner filtering is effective, but filter core stops up easily; 2, oil bath wet-type cleaner is fit to high dirt environment, but it is too many to lose oil, and greasy filth and broken filter screen enter cylinder easily; 3, dried wetting in conjunction with air-strainer though eliminated the shortcoming of dry type and oil bath wet-type cleaner, brought into play their advantage, and its inner dust deposit is more very fast, needs often cleaning.

Summary of the invention

The utility model provides a kind of integrated air filter at the problems referred to above, its objective is the raising filtering efficiency, reduces the deposition of dust in inside.

The purpose of this utility model is achieved in that integrated air filter, it comprises upper casing, lower casing, strainer, dry type filter element, the wet type filter core, suspension rod, suction tude, parts such as steam outlet pipe, its upper casing top is welded with steam outlet pipe, suspension rod and dry type filter element are equipped with in upper casing inside, the wet type filter core is equipped with in lower casing inside, suction tude is housed below or is provided with suction port, strainer links to each other with suction tude, connection part at upper casing and lower casing is provided with seal ring, it is characterized in that, above the wet type filter core oil baffle disc is housed, guide disc is equipped with in the below, and dry type filter element is positioned at the oil baffle disc top to be used.Guide disc and oil baffle disc are located by connecting on the central position of wet type filter core.Strainer is made up of coarse filtration shell, air guide ring, tangentially is installed into tracheae or tangentially leaves several suction ports in the outside of coarse filtration shell, can make the air that enters form swirling eddy, is provided with dust exhausting hole in the bottom of coarse filtration shell.

Owing to adopted such scheme, it has multistage filtering integrated air filter, and dust is at the little deposit of inside, and the filtering efficiency height is to advantages such as the adaptability of environment are good.
