[0025] like Figures 1 to 4As shown, a smoke environmental protection filter bag comprises a box body 1, a filter bag body 2 is arranged inside the box body 1, a support frame is arranged inside the filter bag body 2, an air inlet pipe 6 is fixedly inserted on the left side surface of the box body 1, a support frame 7 is fixedly connected to the surface of the box body 1, a clamping component 3 for limiting the top of the filter bag body 2 is arranged on the top surface of the box body 1, a cleaning component 4 for cleaning the filter bag body 2 is arranged on the surface of the box body 1, a dust collecting tray 5 is clamped on the bottom of the box body 1, and a docking component 8 for controlling the movement of the dust collecting tray 5 is arranged on the surface of the support frame 7. More specifically, the polluted gas is sent into the interior of the box body 1 through the air inlet pipe 6, the smoke is filtered by the filter bag body 2, and finally discharged through the top of the box body 1. The filter bag body 2 can be disassembled and replaced by releasing the limiting effect of the clamping assembly 3. When the filter bag body 2 is blocked, the dust on the surface of the filter bag body 2 can be cleaned by the cleaning assembly 4, and the dust can be pushed downward to the dust collecting tray 5. The dust collecting tray 5 is then driven downward by the docking assembly 8, so that the dust collecting tray 5 and the box body 1 are separated, and the dust falling inside the dust collecting tray 5 can be collected and processed.

[0026] The clamping assembly 3 includes a pressure plate 301, and the pressure plate 301 is pressed on the top surface of the box body 1, and the top of the filter bag body 2 is located between the pressure plate 301 and the box body 1.

More specifically, by rotating the knob 805, the worm 804 is driven to rotate, thereby driving the worm wheel 806 meshed with it to rotate, so that the screw 801 can be controlled to rotate, and at the same time, the worm 804 and the worm wheel 806 can achieve self-locking, thereby ensuring the stability of the screw 801.

[0030] The bottom end of the box body 1 is fixedly connected with a sealing strip 9, and the sealing strip 9 is in contact with the inner wall of the dust collecting tray 5. It should be noted that by providing the sealing strip 9, the contact position between the box body 1 and the dust collecting tray 5 is sealed to prevent smoke from leaking from the contact position.

[0031] In summary: the polluted gas is sent into the interior of the box body 1 through the air inlet pipe 6, the smoke is filtered by the filter bag body 2, and finally discharged through the top of the box body 1.
