Detachable air filter cartridge

Abstract

The present invention relates to a detachable air filter cartridge. The detachable air filter cartridge comprises an upper cover and a lower cover. An inner steel plate mesh and an outer steel plate mesh are arranged between the upper cover and the lower cover. A filter core is arranged between the inner steel plate mesh and the outer steel plate mesh. The detachable air filter cartridge is characterized in that: the inner edge of the upper cover is provided with an inner flanging; the outer edge of the upper cover is provided with an outer flanging; the inner side of the inner flanging is symmetrically provided with at least two locking lugs; the center of the lower cover is provided with a spherical projection; the spherical projection on the lower cover is connected with locking screws; an upper sealing gasket is arranged between the upper cover and the filter core; an lower sealing gasket is arranged between the lower cover and the filter core; the upper cover and the lower cover compress the upper sealing gasket and the lower sealing gasket on both ends of the filter core, the inner steel plate mesh and the outer steel plate mesh by the locking screws and the locking lugs. With the present invention, the detachable structure is adopted, such that the structure is simple, and the installation and the operation are convenient and rapid; only the filter core is required to replace after using, the other parts can be reused, such that the processing cost and the material cost are saved, and the resource waste is reduced; at the same time, the filter core can be transported after folding so as to reduce the transportation cost.

Description

technical field [0001] The invention relates to a filter device in air filter equipment, in particular to a detachable air filter cartridge. Background technique [0002] The air filter cartridge is an important part of various air filtration equipment, and it is used in a large amount. The existing air filter cartridge usually adopts an integrated structure, which is composed of upper and lower end covers and inner and outer cylindrical protective nets. The filter element is installed between the inner and outer cylindrical protective nets. The net is bonded together with sealant, which can only be used once, and cannot be cleaned and regenerated. The used air filter cartridge cannot be recycled, and the service life is short, which wastes a lot of resources. The patent number is 200820039421.5, and the patent document titled "Core-changing Energy-saving Air Filter Cartridge" discloses an air filter cartridge with a replaceable filter element, which adopts the method of bo...
