Problems solved by technology

The function of the air filter is to filter the air inhaled into the engine, prevent foreign matter from being sucked into the engine and increase wear and tear, and prolong the service life of the engine. If there is too much dust on the air filter, it will affect the working condition of the engine and cause the engine to idle. Phenomenon of instability and difficulty in starting
Therefore, the existing road sweepers need to manually clean the air filter after working for about 2-3 days. Most of the cleaning methods use air guns to blow away the dust on the air filter. Poor, low efficiency, easy to cause secondary pollution of dust, and have certain harm to the body of the staff

Abstract

The invention discloses an air filter cleaning method and an air filter cleaning machine adopting the air filter cleaning method. The air filter cleaning method comprises the following steps that (1) air filters are put in the air filter cleaning machine; (2) a top opening and a bottom opening of each air filter are sealed, the air filter cleaning machine is provided with air blowing holes jetting high-speed airflow outwards, and the air blowing holes stretch into inner cavities of the air filters and blow the high-speed airflow from the inner cavities of the air filters to the exterior of the air filters; (3) the heights of the air blowing holes are adjusted through the air filter cleaning machine, so that the high-speed airflow is blown to the inner walls, at different heights, of the air filters, the air filters are rotated through the air filter cleaning machine, and positions blown by the high-speed airflow can be adjusted in the circumferential directions of the air filters; and (4) the air filters are cleaned and taken out, and operation is finished. Human input is saved; airflow losses are small, and the cleaning effect is improved; and the air blowing cleaning positions can be constantly adjusted inside the air filters in the circumferential and axial directions, and thus comprehensive cleaning is realized, and the overall cleaning effect is further improved.

Description

technical field [0001] The invention relates to an air filter cleaning method and an air filter cleaning machine adopting the air filter cleaning method. Background technique [0002] Air filter refers to a device that removes particulate impurities in the air. When the piston machine (internal combustion engine, reciprocating compressor air filter, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so it must be equipped with an air filter. The air filter consists of two parts, the filter element and the housing. Due to the special working conditions of the road sweeper used for municipal work, the working condition of the road sweeper filter is: when the road sweeper engine is working, the air flows in from the gap between the cover and the shell at a very high speed, and Flow down the inner wall of the shell to the oil surface, and then wind up. Due to the sudden change of flow direction, larger dust rushes...
