Embodiment

[0027] Such as figure 1 As shown, an air filter system with self-cleaning function includes three parts: an air filter 1 , a self-cleaning device 2 and a self-dust exhausting device 3 .

[0028] Wherein, the air filter 1, such as figure 2 As shown, it includes a casing 4, a safety filter element 5, a main filter element 6 and a cover 7. The safety filter element 5 is located at the center of the casing 4, and the main filter element 6 is located at the periphery of the safety filter element 5, through its two end covers It is assembled with the cover 7 or the shell 4, and the shell 4 and the cover 7 are fixed by buckling. The top of the safety filter element 5 is provided with a shroud 18, the shroud 18 has a bullet-shaped structure, its top is spherical, and its side is conical, so that the blowback gas introduced from the self-cleaning device 2 is evenly dispersed in all directions. , the dispersed air flow blows up the external particles of the main filter element 6 from...

Abstract

The invention relates to an air filter system having a self-cleaning function. The air filter system comprises an air filter (1) which comprises a shell (4), a safety filter core (5), a main filter core (6) and a cover (7); the air filter system further comprises a self-cleaning device (2) and a self dust exhaust device (3); the self-cleaning device (2) comprises a first air source (9), a first air valve (10), a first air pipe (11) and an air inlet pipe (8) which are connected in sequence; the air inlet pipe (8) is installed on the cover (7); the self dust exhaust device (3) comprises a secondair source (12), a second air valve (13), a second air valve (14), a Venturi dust exhaust pipe (15) and a dust exhaust bag (16); and the Venturi dust exhaust pipe (15) is connected with the shell (4)through a connection pipe (17). Compared with the prior art, the air filter system has the advantages of being long in service life, and capable of adapting to high-particulate polluted environment,protecting human bodies and protecting an engine.

Description

technical field [0001] The invention relates to an air filter system, in particular to an air filter system with self-cleaning function. Background technique [0002] The working process of modern engines is to convert the heat energy released by the combustion of diesel fuel and other fuels into mechanical energy, and a large amount of air is required in the process. In order to ensure the normal combustion of the engine and prevent particulate pollutants in the air from affecting the life of engine parts, the air filter has become an important part of modern cars and engines. [0003] The air filter intercepts particulate matter in the air through the filter element. When the number of intercepted particulate matter reaches a certain level, the intake resistance of the air filter will increase significantly, which will lead to insufficient intake air and insufficient combustion of the engine. Therefore, in order to ensure that the engine continues to work normally, the fi...
