High-performance dedusting air filter

Abstract

The invention discloses a high-performance dedusting air filter. An upper shell and a lower shell are combined together in a clamped mode through a connecting trough. A sealing body is arranged at the bottom of the connecting trough. An air inlet pipe is arranged on one side of the lower shell. An air exhaust pipe is arranged on the other side of the upper shell. A V-shaped air duct flow guide plate is arranged in the upper shell. A filter element is installed in the lower shell. The filter element is a double-layer dedusting net composed of coarse filtering cotton and fine filtering cotton from bottom to top. A filtering element fixing plate is arranged on the outer side of the filtering element and provided with round through holes. The high-performance dedusting air filter is compact in structure, the arrangement space is reduced effectively, and the V-shaped air duct flow guide plate prevents dust from entering the high-performance dedusting air filter. The double-layer dedusting net has the effect of removing dust and sand. The filtering element vibrates to make the dedusting net resonate, and the effect of removing dust on the surface of the coarse filtering cotton is achieved. When an engine runs at a high speed, air suction is conducted, and combustible gas of the engine is effectively prevented from being reversely injected to the filtering cotton of the air filter, so that the service life of the engine is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air filters, and in particular relates to a high-performance dust-removing air filter. Background technique [0002] Garbage cleaning vehicles are becoming more and more popular in Europe due to their low fuel consumption and low carbon dioxide emissions. The development and utilization of technologies such as engines, filters, and new fuels are also gradually enhanced. Diesel vehicles can save 20%-30% of fuel costs compared with gasoline vehicles with the same displacement, and their carbon dioxide emissions are also 20% lower. Preventing global warming is of great significance. The air filter is a device that removes particulate impurities in the air, and consists of two parts: a filter element and a housing.

AI Technical Summary

Problems solved by technology

[0003] The engine needs to inhale a large amount of air when it is working. If the air is not filtered, it will contain a large amount of suspended dust and be sucked into the cylinder together, which will accelerate the wear of the piston group and the cylinder, and it is prone to cylinder scuffing. The function of the air filter is to filter the air To ensure that there is no dust in the air entering the cylinder, but the current air filter has poor sealing effect and shortens the life of the engine
