Efficient air filter

Abstract

The invention discloses an efficient air filter. The efficient air filter comprises an outer shell, a first filtering assembly and a second filtering assembly, wherein the first filtering assembly and the second filtering assembly are arranged inside the outer shell, an air inlet is formed in the top of the outer shell, and an air outlet is formed in the bottom of the outer shell, the first filtering assembly is located on the side close to the air inlet and comprises a rotary shaft which is horizontally arranged below the air inlet and a rectangular hinge which is arranged at the outer circumference surface of the rotary shaft, and the outer surface of the rectangular hinge is coated with a fluff layer, the second filtering assembly is located on the side, close to the air outlet, of the first filtering assembly, and comprises a filtering core, an upper end cover and a lower end cover, and the upper end cover and the lower end cover are fixedly installed at the two ends of the filtering core; the filtering core comprises a center pipe and filtering paper, the outer edge of the upper end cover abuts against the inner wall of the outer shell, and a sealing surface is formed at the contact surface of the outer edge and the inner wall, an air inlet is formed in the upper end cover, and the lower end cover is provided with an air outlet channel which is communicated with the air outlet and a cavity of the center pipe. The efficient air filter is large in ash accommodation volume, high in filtering efficiency and good in filtering effect.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a high-efficiency air filter. Background technique [0002] The air filter is mainly used in pneumatic machinery, internal combustion machinery and other fields. Its function is to provide clean air for these mechanical equipment, so as to prevent these mechanical equipment from inhaling air with impurity particles during work and increasing abrasion and damage. probability. Existing air filters generally rely on a single filter element for filtering, so that the dust holding capacity is generally small, and during the filtering process, the filter holes are easily blocked by flocs or large particles of dust in the air , resulting in premature loss of filtration performance of the filter element. Contents of the invention [0003] Based on the technical problems existing in the above-mentioned background technology, the present invention proposes a high-efficiency air filt...
