Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model provides a modular dust removal filter core, including frame 1 and a plurality of filter core 2, still be equipped with a fixed plate 3 on the frame 1, be equipped with a plurality of through-holes 31 on the fixed plate 3, as shown in fig. 4, form sealed grafting cooperation between one end lateral surface of filter core 2 and through-hole 31. Like this a plurality of filter cores form parallel arrangement, in the airtight space that needs absorbent superficial dirt entering frame 1 formed, under fan negative pressure suction effect, the superficial dirt will be filtered through the filter core, and the air current after being filtered is taken out the back and is discharged.
