Air filter with novel filter element

Abstract

The invention discloses an air filter with a novel filter element. The air filter comprises a shell, a filter element assembly, an air inlet pipe and an exhaust pipe, an inner cavity of the shell is divided into a filter cavity and an exhaust cavity by the filter element assembly, the air inlet pipe is communicated with the filter cavity, and the exhaust pipe is communicated with the exhaust cavity; the filter element assembly comprises filter paper, a fireproof net and a filter paper support which is connected with the periphery of the fireproof net and wraps the filter paper, the two ends of the filter paper are oppositely bent to form wrapping and are vertically arranged, the filter paper support abuts against the filter paper to form the filter cavity, and the filter paper support is provided with a connecting hole to be communicated with the air inlet pipe; the vertically arranged filter paper can block dust after filtering air on the surface of the filter paper, and the dust automatically falls off from the surface of the filter paper under the action of self weight of the dust and vibration of an internal combustion engine, so that accumulation of the dust on the surface of the filter paper is reduced, and the service life of the filter element is prolonged; and meanwhile, the two ends of the filter paper are oppositely bent to form a wrapping space, so that the filtering area of the filter paper can be further increased, and the filtering efficiency of the filter element is improved.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to an air filter with a novel filter element. Background technique [0002] The air filter is used in equipment with an internal combustion engine to filter the dust in the air, and the dust in the air is filtered through the filter element inside the air filter. Generally, the closer to the ground, the more dust there is. Therefore, the air inlet of the air filter is generally set upwards, so that the air inlet is not easy to inhale dust, and the general filter element is flat and placed horizontally, but the filter element placed horizontally is less likely to absorb dust. The filter paper is also arranged horizontally. Therefore, the dust filtered by the filter paper falls on the surface of the filter paper under the action of gravity, and slowly accumulates to block the filter paper, making the air filter prematurely scrapped and shortening the service life of the air filter...

Problems solved by technology

Generally, the closer to the ground, the more dust there is. Therefore, the air inlet of the air filter is generally set upwards, so that the air inlet is not easy to inhale dust, and the general filter element is flat and placed horizontally, but the filter element placed horizontally is less likely to absorb dust. The filter paper is also arranged horizontally. Therefore, the dust filtered by the filter paper falls on the surface of the filter paper under the action of gravity, and slowly accumulates to block the filter paper, making the air filter prematurely scrapped and shortening the service life of the air filter. In the same filter space, The filter paper arranged horizontally can generally improve the filtration efficiency by lengthening or widening the length or width of the filter paper, but after lengthening or widening the size of the filter paper, the size of the filter element will also increase, which will affect the layout space of the air filter in the equipment
