Air filter of diesel engine

Abstract

The invention discloses an air filter of a diesel engine. The air filter comprises a water tank, a gas guide tube, a gas inlet tube, a fan and a filter, wherein a gas inlet, a gas outlet, a water filling hole and a water outlet are formed in the water tank; a gas distributing tube is arranged on the bottom of the water tank; an aeration head is mounted on the gas distributing tube; a pore plate is arranged on a position, above the gas distributing tube, in the water tank; at least two particle filling layers are arranged above the pore plate; one end of the gas guide tube is connected with the gas inlet tube; one end, far from the gas inlet end, of the gas guide tube penetrates through the gas inlet of the water tank, extends into the water tank, and is communicated with the gas distributing tube; a dustproof net is arranged in the gas inlet tube; a dust removal tube and an air inlet are formed in the side wall of the gas inlet tube; center lines of the dust removal tube and the air inlet are arranged on the same straight line; a fan is mounted at the air inlet; the filter is positioned at one side of the water tank; and the filter is connected with the gas outlet of the water tank. According to the air filter, the filter efficiency is greatly improved, so that air entering the diesel engine is kept clean, damages to the diesel engine are avoided, and the service life of the diesel engine is prolonged.

Description

technical field [0001] The invention relates to the field of diesel engine accessories, in particular to an air filter for a diesel engine. Background technique [0002] Diesel engines are widely used in agricultural machinery. Due to the poor operating environment of agricultural machinery, the air often contains a lot of impurities mixed with various substances such as floating dust, fluff, and particles. If the air entering the diesel engine is not filtered Protection, it is easy to cause damage to the diesel engine and affect the service life of the diesel engine. However, the traditional diesel engine air filter does not classify and filter the air impurities in the environment where the diesel engine is used according to the actual situation, but only filters them through the filter element device. The filter efficiency is too low, resulting in a large part of the air Impurities enter the diesel engine and cause damage to the diesel engine. Contents of the invention...
