8. A method for using a furnace exhaust gas treatment device for aluminum rod smelting, according to any one of claims 1 to 7, characterized in that: The method of use comprises the following steps: Insert the mounting frame (4) into the wind collecting hood (3) so that the concave positioning plates (404) on both sides of the mounting frame (4) are stuck in the corresponding positioning slots (301) on both sides of the wind collecting hood (3), tighten the fixing bolts (405) through the concave positioning plates (404) and connect them to both sides of the wind collecting hood (3), so that the mounting frame (4) is fixed in the wind collecting hood (3), and then insert the filter frame (5) into the top of the wind collecting hood (3), so that the limiting grooves (501) on both sides of the filter frame (5) correspond to the positions of the limiting rollers (303) on both sides of the inner wall of the wind collecting hood (3), so that the limiting grooves (501) are stuck in the corresponding surfaces of the limiting rollers (303), until the filter frame (5) is completely inserted into the wind collecting hood (3), so that the filter plate (503) and the cleaning scraper (312) are tightly attached, and the pressure is pressed. The clamping plate (311) is pressed against the mounting plate (308) to squeeze the clamping spring (313) between the mounting plate (308) and the clamping plate (311) to deform, so that the cleaning scraper (312) can be closely attached to the surface of the filter plate (503), and then the two sets of fixing plates (8) are correspondingly clamped on both sides of the exhaust frame (6), so that the T-shaped slot (802) is clamped on the surface of the corresponding T-shaped block (602), until the position of the air pipe (801) corresponds to the position of the exhaust port (601), the rotating stud (603) is controlled to rotate and clamp into the inside of the fixing block (803), and the fixing nut (604) is tightened, and the two sets of fixing plates (8) are clamped and fixed on both sides of the exhaust frame (6), and an appropriate amount of waste gas treatment reagent is injected into the inside of the treatment box (7), so that the reagent submerges the exhaust hole (804) on the surface of the air pipe (801); After the bottom plate (1) is pushed to move to a suitable position, the fan (402) is started to suck the furnace exhaust gas into the wind collecting hood (3). After the exhaust gas passes through the filter plate (503), the solid particles contained in the exhaust gas are filtered. The filtered solid particles are accumulated on one side of the filter plate (503). The dual-axis motor (304) is controlled to rotate forward and reverse to drive the two sets of bevel gears (306) to rotate synchronously, thereby controlling the two sets of moving screws (305) to rotate synchronously, so that the two sets of moving sleeves (307) move up and down synchronously on the surface of the corresponding moving screw (305), driving the cleaning scraper (312) to move on one side of the filter plate (503). The cleaning scraper (312) moves up and down, and under the rebound effect of the compression spring (313), the cleaning scraper (312) is pressed against the surface of the filter plate (503) to scrape and clean the surface of the filter plate (503) to prevent solid particles from clogging the filter plate (503). The waste gas filtered by the filter plate (503) is input into the exhaust rack (6), discharged into the air pipe (801) from the exhaust ports (601) on both sides of the exhaust rack (6), and discharged into the treatment box (7) through the exhaust holes (804) on the surface of the air pipe (801), so that the harmful substances in the waste gas fully react with the treatment reagent in the treatment box (7), and the waste gas is treated harmlessly or at a low harm level.
