Abstract
The utility model relates to a two-stage air cleaner assembly structure and is characterized in that the structure is composed of a main filter element assembly and a two-stage paper filter element assembly; the main filter element assembly is arranged on the outside of the two-stage paper filter element assembly and sealed with a front end cover by a radial pressure provided by a back end cover, the two-stage filter element assembly is sealed fixedly with the front end cover by a screw thread and a sealing ring. The two-stage air cleaner assembly structure has the advantages of two-stage filtration performance, good air-tightness and easy current maintenance; thereby when the main filter element fails to work, the two-stage filter element assembly is capable of guaranteeing the filtration performance of the whole air-cleaner assembly.
Description
Technical field
The utility model belongs to the technical field of sky filter, particularly a kind of double-stage air cleaner assembly structure.
Background technique
Our the empty filter assembly that uses comprises main filter core and safe filter core at present, and the filtering material of safe filter core is a nonwovens, and its filter efficiency is low, hold grey ability, and big foreign material do not enter the intake duct of rear end in the time of can only protecting change owner filter core more.The function that does not have cascade filtration.
Summary of the invention
At the said structure defect situation, the utility model purpose provides a kind of double-stage air cleaner assembly structure.
The technical solution of the utility model is achieved in that
The double-stage air cleaner assembly structure, it is characterized by: it is to be made of main filter core assembly and secondary filter core assembly, main filter core assembly is in the outside of secondary filter core assembly, by radial pressure and front cover sealing that rear end cover provides, the secondary filter core assembly adopts screw thread and seal ring and front cover fixing seal.
The utlity model has the double-stage filtering performance, the secondary filter core assembly can guarantee the characteristics of the strainability of whole empty filter assembly under main filter core failure conditions.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The double-stage air cleaner assembly structure, it is characterized by: it is to be made of main filter core assembly and secondary filter core assembly, main filter core assembly 1 is in the outside of secondary filter core assembly 2, by radial pressure and front cover sealing that rear end cover provides, secondary filter core assembly 2 adopts screw thread and seal ring and front cover fixing seal.
As shown in Figure 1, the end face of main filter core assembly adopts the polyurethane moulding, adopts general radial seal, is convenient to user's operational maintenance; And the secondary filter core assembly is a rotation fitting type paper air cleaner filter core assembly, adopts screw thread and seal ring fixing seal mode, the whole assembly fitting tight of more reliable assurance.
Whole empty filter adopts modular design, and the installation dimension of empty filter assembly is identical with the existing product of producing with external dimension, guarantees empty filter of integral type twin-stage and the product interchangeability of now producing empty filter assembly; And also can guarantee the interchangeability of filter core assembly.
