Description

Composite adsorption type air filter
Technical Field
The invention belongs to the technical field of automobile parts, and particularly relates to a composite adsorption type air filter.
Background
The air filter is a filter, which is called as an air filter cartridge, an air filter element, a style and the like. The air filter is mainly used for filtering air in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operation rooms and various precision operation rooms.
When the engine is in operation, a large amount of air needs to be sucked, and if the air is not filtered, dust suspended in the air is sucked into the cylinder, so that the abrasion of the piston group and the cylinder is accelerated. Larger particles enter between the piston and the cylinder, causing severe "scuffing" phenomena, which is particularly severe in dry, sandy working environments. The air filter is arranged in front of the carburetor or the air inlet pipe, plays a role in filtering dust and sand grains in air and ensures that sufficient and clean air enters the air cylinder.
Present air cleaner adopts mostly to place the filter core in the casing, fix with the goat's horn screw and press from both sides tightly, the function that the mode sealed is realized to the sealing washer through the filter core both sides, but this kind of structure can not be according to the size automatically regulated air cleaner's that the engine inhales the air current effective work area, long-time back of using, when the filter core adsorbs dust and moisture when too much, the intensity and the toughness of filter core all can descend, increase suddenly when engine power, the filter paper material of filter core probably is blown brokenly, the wastepaper can probably be inhaled the engine, cause "scuffing of a cylinder" phenomenon.
Disclosure of Invention
The invention aims to provide a composite adsorption type air filter, which solves the specific problems that the conventional air filter cannot automatically adjust the effective working area of the air filter according to the size of air flow sucked by an engine, after the air filter is used for a long time, when a filter element adsorbs excessive dust and moisture, the strength and toughness of the filter element are reduced, when the power of the engine is suddenly increased, a filter paper material of the filter element can be blown open, paper scraps can be sucked into the engine, and the phenomenon of cylinder pulling is caused.
