Efficient air filter assembly

Abstract

The invention discloses an efficient air filter assembly which comprises a front filter and a rear filter. An air inlet pipe is arranged on the left side of the front filter; a first air outlet pipe is arranged on the right side of the front filter; the right end of the first air outlet pipe is connected with the rear filter; the right end of the rear filter is connected with a second air outlet pipe; the front filter is in a box shape; a first filtering assembly, a second filtering assembly and a third filtering assembly are arranged in the front filter; the first filtering assembly is located at the left end of the front filter; the second filtering assembly is located in the middle of the front filter; the third filter is positioned at the right end of the front filter; and the first filtering assembly comprises a dust removal plate. By means of the device, air is filtered more thoroughly, and air entering an engine air cylinder assembly is cleaner.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an efficient air filter assembly. Background technique [0002] An air filter is a device that removes particulate impurities from the air. When the piston machine (internal combustion engine, reciprocating compressor, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear of the parts, so an air filter must be installed. The air filter consists of two parts, the filter element and the housing. The main requirements of the air filter are high filtration efficiency, low flow resistance, and continuous use for a long time without maintenance. [0003] Today's combustion engines use air filters to filter out impurities in the air so that air can enter the engine to participate in combustion. The air filter elements used in traditional air filters are all single-layer filter paper, which is then folded into a wavy structure. T...

Problems solved by technology

Due to the high air humidity in some areas and seasons, the filter paper is easy to be damp, which leads to an increase in filter resistance, affects the intake of the engine, reduces the engine power, increases the amount of gasoline sucked in, causes the mixing ratio to be too rich, increases fuel consumption, and is prone to Carbon deposit

[0005] In order to prolong the service life of automobile engines and reduce the dust-holding load of paper air filters, the air intake systems of trucks and construction machinery with generally harsh working environments have a first-stage oil-bath air filter in front of the paper air filter. Filter, the existing oil-bath air filter has the following disadvantages: since the air in the intake pipe enters the filter oil basin, it can only contact with its oil surface, and its contact area is small, so that dust passes through the filter mechanism Afterwards, its filtration rate is low, which increases the filtration burden of the subsequent air filtration mechanism, resulting in low filtration efficiency and affecting use.
