Abstract

The invention relates to a dry-type air cleaner which comprises a maintenance warner, a front blocking cover, an air intake cap sub-assembly, vane rings, a main filter element, a safety filter element, a shell, a dust accumulation plate cover, a rear cover, a pull rod sub-assembly, a dust removal bag, a sealing ring and an air outlet pipe, wherein the dust accumulation plate cover is arranged between the right end of the main filter element and the rear cover. The dry-type air cleaner is reasonable in structure. Dust setting to the bottom of the rear cover under the action of centrifugal force of the vane rings cannot be absorbed back to the surfaces of the filter elements any more through the negative pressure effect generated by an engine. The dry-type air cleaner has the advantages of being high in filter precision, long in service life, long in maintenance period, low in maintenance cost and the like, thereby saving materials, reducing consumption, prolonging the service life of the engine and being capable of being widely used for being matched with heavy-duty cars.

Description

technical field [0001] The invention belongs to the field of air filters, in particular to a dry air filter suitable for Euro IV and Euro V emissions. Background technique [0002] The air filter is a part of the engine intake system. Its function is to filter out the dust in the intake air, provide clean air for the system, protect the cylinder, piston and piston ring of the engine, and prolong the service life of the engine. With the continuous and rapid development of modern industry, it is the current development trend of the automobile industry to improve the high precision and long life of the air filter. With the rapid development of the automobile industry, the filter industry is improving performance. There is also an urgent demand, and at the same time, the maintenance frequency of the air filter is reduced, and the cost of use is reduced. Contents of the invention [0003] The object of the present invention is to provide a dry-type air filter to solve the prob...
