Abstract

The invention discloses a double-layer drawable air filtration method. Specifically, reasonable judgment is firstly carried out according to the practical situation, the overall length of an air filter core is lengthened properly, the length of the air filter core depends on the cooperation of an outer protective pipe and a central filter core, the whole air filter core is designed into a drawablestructure, a guard plate and grooves cling to each other closely, a casing pipe is sleeved outside a draw pipe, when the central filter core moves relative to the outer protective pipe, the casing pipe is pulled out upward along the draw pipe, thus ensuring the linearity of the air filter core, a rotary sleeve is rotated, under the action of steel balls, rotation occurs to the rotary sleeve and asupport disk, the positions of connecting sleeves change correspondingly, 4 connecting sleeves are disposed at the same time, and provide multiple installation sites for the air filter core, thus being convenient for the installation and debugging of the air filter core.

Description

technical field [0001] The invention relates to the technical field of purification devices, in particular to a double-layer drawable air filtration method. Background technique [0002] The air filter element is a kind of filter, also known as air filter cartridge, air filter, style, etc. It is mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, aseptic operating rooms and various precision operating rooms. 1. The engine takes in a lot of air during its working process. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and the cylinder. [0003] The length of the existing air filter element is limited, the matching degree of the complex mechanism is poor, and the air purification efficiency is not high. The structure of the filter paper core is usually laminated and distributed. The installation design plays a particularly...
