Novel filtering mesh bag

The utility model discloses a novel filtering mesh bag and relates to the field of filtering equipment. The novel filtering mesh bag comprises a filtering bag body interwoven from and defined by warp and weft, wherein openings are formed in upper and lower ends of the filtering bag body to form an upper bag opening and a lower bag opening respectively, a plurality of shaping devices are arranged on the inner side surface or the outer side surface of the filtering bag body in the axial direction of the filtering bag body, each shaping device comprises two arc-shaped pieces, n-shaped buckles and two clamping seats for clamping the arc-shaped pieces, every two clamping seats are symmetrically arranged about the axis of the filtering bag body, two clamping grooves are formed in any clamping seat in the direction perpendicular to the axis of the filtering bag body, each buckle is arranged between two adjacent clamping seats, one end of each arc-shaped clamping piece is clamped in one of two corresponding clamping grooves, and the other end of each arc-shaped clamping piece is clamped in the other clamping groove after penetrating through the buckles in the direction perpendicular to the axis of the filtering bag body. The arc-shaped pieces, the buckles and the clamping seats are arranged, so that the shaping devices are detachably connected onto the filtering bag body, and the novel filtering mesh bag has the characteristics of convenience in mounting and dismounting and low probability of damage.
