Heavy-duty diesel engine air filter

Abstract

The invention discloses a heavy-duty diesel engine air filter. The heavy-duty diesel engine air filter comprises a box body, the box body is provided with an air inlet and an air outlet, a partition plate is arranged between the air inlet and the air outlet, the partition plate divides the box body into two parts of a dry filter part and a wet filter part, a ventilation opening is formed in the partition plate, a fan is arranged in the dry filter part, the fan is arranged beside the air inlet and provides power for air inlet in the box body, a filter screen and a filter element are arranged inthe dry filter part, the filter screen is arranged between the air inlet and the ventilation opening; and the filter element is also arranged between the air inlet and the ventilation opening; a filtrate is arranged in the wet filter part, a ventilation pipe is further arranged on the partition plate, an inlet of the ventilation pipe is in communication with the ventilation opening, and an outletof the ventilation pipe is arranged below the liquid level of the filtrate. The diesel engine air filter has the advantages that a triple filtering device is used for filtering air, compared with a common diesel engine, air entering the diesel engine is guaranteed to be free of excessive impurities, and the use period of the diesel engine is longer.

Description

technical field [0001] The invention relates to the technical field of air filters, in particular to a heavy-duty diesel engine air filter. Background technique [0002] At present, diesel engines are widely used in agricultural machinery. Since commercial diesel engines have been used for a long time, the air often contains a lot of impurities. If the air entering the diesel engine is not filtered and protected, it is easy to cause damage to the diesel engine and affect the use of the diesel engine. life. The air filter is the core device for removing particulate impurities in the air. [0003] However, the traditional diesel air filter only filters it through the filter paper device, and the filtration efficiency is poor, and a large part of the impurities in the air are likely to enter the diesel engine, causing damage to the diesel engine. Contents of the invention [0004] The purpose of the present invention is to solve the above problems and provide a heavy-duty d...
