Air filter device

Abstract

The invention relates to an air filter device which comprises a second shell (2), a filter element, a first turbine (3), a first turbine hood (4), a first rotary shaft (5) and a scraping blade (6). The filter element is cylindrical. A second air outlet (19) communicates with a filter element inner cavity through an inner cavity of the first turbine hood (4). The first turbine (3) and the filter element are both connected to the first rotary shaft (5). The first turbine (3) is located in the inner cavity of the first turbine hood (4) and rotationally connected with the first turbine hood (4) through the first rotary shaft (5). The filter element is rotationally connected with the second shell (2) through the first rotary shaft (5). One end of the scraping blade (6) is tightly attached to the peripheral wall of the filter element. The air filter device has the advantages that when in use, the air filter device can remove dirt such as dust and fine sand adsorbed to the surface of the filter element, accordingly, the air inlet amount of an engine is guaranteed, the engine can stably and normally work, and further, the service life of the filter element is greatly prolonged.

Description

technical field [0001] The invention relates to a filter, in particular to an air filter device. Background technique [0002] The air filter is mainly set in the engine intake system. It is an assembly composed of one or several clean air filter components. Its main function is to filter out harmful impurities in the air that will enter the cylinder to reduce the air intake of the cylinder. , Early wear of pistons, piston rings, valves and valve seats. At present, in order to ensure that the engine has sufficient air intake, existing vehicles such as automobiles generally communicate with the air inlet between the air filter and the air intake grille at the front end of the engine room of the vehicle, so that when the vehicle is running In this process, the air outside the vehicle can quickly enter the engine. However, due to the poor air quality in some parts of the country, especially in northern China, the air contains a large amount of dust and sand, so when the air o...

Problems solved by technology

However, due to the poor air quality in some parts of the country, especially in northern China, the air contains a large amount of dust and sand, so when the air outside the vehicle directly enters the air filter through the bleed pipe, it will greatly increase the air quality. The working load of the filter makes the filter element of the air filter easy to become dirty, and the dirty filter element will often lead to insufficient air intake of the engine, resulting in incomplete combustion of fuel, which will cause the engine to work unstable, and the engine will fail. The power drops and the fuel consumption increases. Therefore, in order to ensure the normal operation of the engine, the filter element of the air filter can only be replaced. This not only greatly increases the cost of the vehicle, but also undoubtedly greatly reduces the cost of the air filter element. service life
