Vibration type self-cleaning method and device for air filter screen

Abstract

The invention discloses a vibration type self-cleaning method and device for an air filter screen. The device comprises the air filter screen (1), a gas vibration device and an air filter screen and gas vibration device relative movement mechanism, wherein the gas vibration device is arranged on one side of the air filter screen (1), compressed air in an compressed air source (3) of the gas vibration device flows into an air inlet cylinder (8) through a high pressure air tube (4), a plurality of ultrasonic whistles (9) are arranged on the air inlet cylinder (8), and airflow outlets (17) of the ultrasonic whistles (9) are opposite to a filter screen of the air filter screen (1). When the gas vibration device works, the air filter screen and gas vibration device relative movement mechanism works to generate ultrasonic vibration at different sites of the air filter screen (1) so as to carry out real-time automatic cleaning on the air filter screen (1), so that the service life of the air filter screen (1) is prolonged, and the filtering quality of the air filter screen (1) is improved.

Description

technical field [0001] The invention relates to an air filter cleaning method and device, belonging to the technical field of air filtration and purification. Background technique [0002] At present, the global industry and infrastructure are developing at an unprecedented speed, especially the emissions from metallurgy, mining, cement and other production enterprises, as well as the dust brought by outdoor construction such as roads, bridges, railways, and urban infrastructure, resulting in serious air pollution and suspended particles. , Dust seriously exceeds the standard; for this reason, in many industries, it is necessary to filter the air inside the inhaled equipment to remove granular dust, harmful suspended matter, etc., so an air filter is installed on the air channel entering the equipment; but with the air The pollution is getting more and more serious, and the air filter is becoming more and more overwhelmed. It is necessary to manually replace the air filter o...

Problems solved by technology

[0002] At present, the global industry and infrastructure are developing at an unprecedented speed, especially the emissions from metallurgy, mining, cement and other production enterprises, as well as the dust brought by outdoor construction of roads, bridges, railways, urban infrastructure, etc., resulting in serious air pollution, suspended particles , Dust seriously exceeds the standard; for this reason, in many industries, it is necessary to filter the air inside the inhaled equipment to remove granular dust, harmful suspended matter, etc., so an air filter is installed on the air channel entering the equipment; but with the air The pollution is getting more and more serious, and the air filter is becoming more and more overwhelmed. It is necessary to manually replace the air filter or clean the dirt on the filter, which is time-consuming and laborious, and the labor intensity and use cost increase; when the dirt on the air filter accumulates To a certain extent, if the dirt on the filter is not replaced in time or manually cleaned, the air filter will be blocked or damaged, which will seriously affect the air intake quality of the equipment, resulting in poor operation or even damage to the equipment.

For example, for trucks working in deserts or areas with severe air pollution, the air filter screen of the engine intake is easily blocked or damaged, resulting in insufficient intake air in the engine combustion chamber or the quality of intake air cannot meet the requirements, and the power of the vehicle is seriously reduced. cause engine damage
