[0010] Beneficial effects

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the bag filter can extract the air from the inner cavity of the connecting box through the operation of the fan, and form a negative pressure in the inner cavity of the connecting line, so that the dust at the screening of the external equipment can enter the inner cavity of the connecting box through the ash inlet and adhere to the outer wall of the filter bag. By moving the connecting cover to the left, the connecting cover can be driven to separate from the first permanent magnet, and by moving the cross bar to the right at the same time, the connecting column can be released, and the filter bag can be easily removed. The device can collect dust during screening to prevent dust from polluting the surrounding environment, and the filter bag can be easily replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 The utility model provides a bag filter, including an external device 1. The external device 1 is existing technology and can be adapted to the device without special model requirements. A connection box 2 is installed on the left side of the external device 1, and a filter mechanism 3 is installed in the inner cavity of the connection box 2. Dust can be conveniently collected through the filter mechanism 3.

[0018] As a preferred solution, the filtering mechanism 3 includes an ash inlet 31, a fan 32, a partition 33, a connecting column 34, a through hole 35, a filter bag 36, a cross bar 37, a first permanent magnet 38 and a connecting cover 39. An ash inlet 31 is provided at the bottom end of the right side of the connecting box 2, and a fan 32 is installed on the left side of the connecting box 2. The fan 32 is of existing technology and can be adapted to this device without requiring a special model. A partition 33 is installed in the inner cavity of the connecting box 2, and connecting columns 34 are installed at the left and right ends of the top of the partition 33, and the bottom end of the connecting column 34 extends out of the partition 33. A through hole 35 is provided at the top of the connecting column 34, and a filter bag 36 is installed at the bottom end of the connecting column 34, through which dust can be adsorbed, and a cross bar 37 is installed in the inner cavity of the through hole 35, and a first permanent magnet 38 is installed on the left side of the cross bar 37.
