[0005] In one embodiment, the shape of the side plate is adapted to the shape of the two filter cloths.

[0006] In one embodiment, the connecting plate and the frame are detachably connected by means of threaded connection.

[0007] In one embodiment, a magnet is fixed on one of the connecting plate and the frame, and an iron block is provided on the other. The position of the magnet corresponds to the iron block, and the connecting plate and the frame are detachably connected by the attraction between the iron block and the magnet.

[0019] See also Figure 1 、 Figure 3 A multi-bag air filter includes a frame 7 and a plurality of new filter bags 10. The frame 7 is provided with a plurality of penetrating mounting grooves 8 arranged equidistantly along a straight line to provide mounting positions for the new filter bags 10. Each of the new filter bags 10 is arranged in one of the mounting grooves 8, and a plurality of the new filter bags 10 are arranged side by side on the frame 7.

[0020] See also Figure 2 Each of the novel filter bags 10 includes two parallel front and rear side panels 1 and two filter cloths 2 vertically stretched between the two side panels 1. Viewed from the front and rear, the two filter cloths 2 are arranged in a V-shape with the pointed ends facing downward. The front and rear sides of each filter cloth 2 are fixedly connected to the side panels 1 by gluing or embedding. In one embodiment, a connecting strip 4 perpendicular to the side panels 1 is fixed at the bottom ends of the two filter cloths 2 (at the pointed ends of the V-shape) between the two side panels 1 in each novel filter bag 10. Both filter cloths 2 are connected to the connecting strip 4 by gluing or embedding. This arrangement provides a more stable connection between the two filter cloths 2.

[0021] See also Figure 2 In one embodiment, the shape of the side panel 1 is adapted to the shape of the two filter cloths 2. The side panel 1 is an isosceles trapezoid with the upper base at the bottom, and the two waists of the trapezoid are parallel to the setting direction of the two filter cloths 2. This arrangement can save the material of the side panel 1 as much as possible while providing a connection position for the filter cloth 2.

[0022] See also Figure 2 、 Figure 4 、 Figure 5Between the two side panels 1 in each of the new filter bags 10, a connecting plate 3 is fixed to the upper ends of the two filter cloths 2. The connecting plate 3 is perpendicular to the side panels 1, and both ends of the connecting plate 3 are fixedly connected to the side panels 1 by welding or bonding. Each of the new filter bags 10 is detachably connected to the mounting groove 8 through the connecting plate 3 and is installed in the filter through the frame 7 (the installation here is generally by threaded connection or clamping).

[0023] See also Figure 5 In one embodiment, the connecting plate 3 is provided with a through hole, and the frame 7 is provided with a threaded hole. Each through hole corresponds to a position of the threaded hole, and a bolt 6 is provided to pass through the through hole and screw into the threaded hole. The connecting plate 3 and the frame 7 are detachably connected by a threaded connection. This arrangement is easy to implement and has a relatively stable effect.

[0024] See also Figure 2 、 Figure 3 In one embodiment, four magnets 9 are bonded and embedded in each mounting groove 8 on the frame 7, and four iron blocks 5 are fixed at corresponding positions on each connecting plate 3. The connecting plate 3 and the frame 7 are detachably connected through the attraction between the iron blocks 5 and the magnets 9. This arrangement makes operation more convenient.

[0025] Working principle: The new filter bag 10 achieves the filtering effect by replacing the original filter bag structure with two filter cloths 2 arranged in a V shape. The two filter cloths 2 will not open as the wind pressure increases, avoiding contact between the two adjacent new filter bags 10, without affecting the filtering effect or increasing wind pressure resistance, thereby reducing unnecessary energy consumption.
