The using method of the invention is as follows:
in the using process, when the furnace mouth bin door is opened, the internal high-temperature airflow flows into the interior of the collecting hopper 1 and cannot directly contact with the inductor 4 under the blocking action of the partition plate 3, because the density is lower than that of air, the internal high-temperature airflow can gather at the top of the inner cavity of the partition plate 3, the distance between the high-temperature air in the partition plate 3 and the inductor 4 is continuously close and finally contacted with each other along with the larger volume of the high-temperature air entering the interior of the collecting hopper 1, and because the temperature of the air in the interior of the collecting hopper 1 is different, the internal air is in density gradient arrangement, the air in the furnace with slightly lower temperature can be positioned at the lowest position and firstly contacts with the inductor 4 and triggers the inductor 4, the air pump 13 can pump the air in the interior of the straight flue 2 and the inclined flue 7 when in operation, so that the pressure in the straight flue 2 and the inclined flue 7 is reduced, and the stroke plate 104 moves along the vertical downward direction in the graph 9 under the action, until the stroke plate 104 and the insulating sleeve 107 contact with each other, because of the insulating property of the insulating sleeve 107, a passage cannot be formed among the trigger ring 105, the trigger rod 106 and the stroke plate 104, so that the pump motor 13 is in a closed state, after the rotary partition plate 5 and the rotary folding plate 15 are opened, the low pressure in the straight flue 2 and the inclined flue 7 can generate a large enough instant suction force to enter the collecting hopper 1 to collect flue gas and dust, and the normal stroke plate 104 can reset under the action of the reset spring 103 along with the pressure in the straight flue 2 and the inclined flue 7, so that the pump motor 13 is in a working state again, so as to suck the waste gas and dust in the collecting hopper 1, when the furnace mouth closes, the temperature in the collecting hopper 1 is reduced again, so that the rotary partition plate 5 and the rotary folding plate 15 are closed, at this time, the pressure in the straight flue 2 and the inclined flue 7 is reduced again, and the pump motor 13 is in a closed state again, thereby realize that the automation of pump mechanism of qi 13 stops, the inside low pressure of straight flue 2 and oblique flue 7 is rotating baffle 5 and rotating folded plate 15 and is opening the high-speed air current of production and can drive coil blade pivot 83 and rotate, thereby make coil blade pivot 83 cut the magnetic induction line of magnet stick 82 and produce the electric current, make the electromagnetism board 9 circular telegram and carry magnetism, thereby make the piece in the flue gas dust absorb, after rotating baffle 5 and rotating folded plate 15 and closing, the inside air current of straight flue 2 and oblique flue 7 disappears and makes the electromagnetism board 9 lose magnetism, the piece that electromagnetism board 9 surface adsorption can fall down and rotate folded plate 15 top, and follow relief groove 17 and discharge and collect from relief hole 14 department when rotating folded plate 15 next time opens.
