Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of filtering equipment, and particularly relates to a bag type filtering assembly, in particular to an innovative structural design capable of sealing and fastening the bag opening of a filtering bag body on a frame body. BACKGROUND

[0002] In places with high clean air grades or places where fiber shedding is not allowed, such as hospitals, pharmaceutical factories, paint spray rooms, office buildings, factories, dust-free rooms, computer rooms, and even machine equipment such as gas turbine machines, air filtering equipment is provided to effectively filter dust to maintain a dust-free environment.

[0003] The filtering assembly used in common air filtering equipment is in the form of a flat plate, and the size of the limited filtering window limits the filtering area, and the filtering efficiency cannot be effectively improved.

[0004] Please refer to the "fresh air bag filter" with the announcement number CN202983413U, which mainly sets a plurality of parallel filtering bags in the frame, and improves the limitation of the filtering area of the traditional flat plate type filtering assembly through the setting of the filtering bag.

[0005] However, the "fresh air bag filter" with the announcement number CN202983413U solves the problem of the filtering area, but the assembly relationship between the frame and the bag opening of the filtering bag is not further discussed in the case.

[0006] In addition, the existing frame material is metal, so the way to fix the bag opening of the filtering bag to the frame is to manually put the bag opening of the filtering bag one by one around each inner frame, and then put the inner frame in the outer frame one by one, and lock the screw into the outer frame with a pneumatic tool, and finally embed the connecting frame between the two adjacent inner frames, which are dependent on each other, and the bag opening of the filtering bag is simultaneously clamped by the embedding of the connecting frame, and the filtering bag is assembled and fixed.

[0007] However, the assembly process between the existing filtering bag, inner frame and outer frame requires a large amount of manual work, cannot be mass-produced, and the production cost cannot be effectively reduced.

[0008] Therefore, the present inventor develops the structure of the bag opening of the filtering bag combined with the frame. CONTENT OF THE UTILITY MODEL
