Embedded self-sealing type air filter element

Abstract

The invention discloses an embedded self-sealing type air filter element. The embedded self-sealing type air filter element comprises a filter element main body, a rolling layer, a left sealing deviceand a first sealing ring; a drying net is arranged on the outermost layer of the filter element main body; an isolating layer is arranged on the inner side of the first filter element; rolling ballsare arranged in the rolling layer; a second filter element is arranged on the inner side of the rolling layer; fixed rings are arranged on the two sides of the second filter element; rotating shafts are arranged on the two sides of a mounting shaft; a first sealing ring is arranged on the right side of the internal part of the left sealing device; a right sealing device is arranged on the right side of the filter element main body; a second sealing ring is arranged on the left side of the first sealing ring; a rotating shaft hole is formed in the middle part of an outer protective ring; and aconnecting bearing is arranged on the outer side of the rotating shaft. The embedded self-sealing type air filter element has high sealing property, can perform self sealing under the condition of notusing external equipment and guarantees the air purification quality.

Description

technical field [0001] The invention relates to the technical field of air filter elements, in particular to an embedded self-sealing air filter element. 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. , The engine needs to inhale a large amount of air during the 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, and larger particles will enter between the piston and the cylinder. , will cause a serious "squeeze cylinder" phenomenon, which is especially serious in a dry and sandy working environment. The air filter is installed in front of the carburetor or the intake pipe to filter out d...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a built-in self-sealing air filter element to solve the above-mentioned background technology. In order to ensure the quality of purification in the process of use, the general air filter element often needs to be used under sealed conditions, but The existing air filter itself does not have a closed condition. Once the external sealing environment is damaged, the working efficiency and purification quality of the air filter will be greatly reduced.
