The filter assembly comprises a pair of second rotating shafts 21 inserted and rotated on both sides of the treatment box 1, a second fixed plate 20 is fixedly connected to the outer wall of the second rotating shaft 21, a first fixed plate 18 is arranged on the outer wall of the second fixed plate 20, and a uniformly distributed filter plate 17 is fixedly connected to one side of the first fixed plate 18, and an inlet 2 and a pair of discharge parts 4 are respectively arranged on the input side and the output side of the treatment box 1. A collecting portion 5 is provided at the bottom of the processing box 1. The collecting portion 5 includes a pair of collecting boxes 6, and the collecting boxes 6 correspond to the filtering components. A discharge hole is opened at the bottom of the collecting box 6. The flue gas can be diverted by setting the inlet portion 2. The flue gas enters the interior of the processing box 1 through the inlet portion 2. The dust contained in the flue gas is absorbed by the filtering components and leaves the interior of the processing box 1 through one of the discharge portions 4. The dust falling from the filter plate 17 can be collected by setting the collecting box 6.

[0015] The entrance portion 2 includes a first shell 11 fixedly connected to the output side of the treatment box 1, a second shell 12 is inserted and fixedly connected inside the first shell 11, a pair of through holes 13 are opened on the side of the second shell 12 close to the treatment box 1, and the side of the second shell 12 close to the treatment box 1 is set as a semicircular structure, a first rotating shaft 16 is inserted and rotatably connected to the bottom of the inner wall of the second shell 12, a transition portion 15 adapted to the semicircular structure is fixedly connected to the top of the first rotating shaft 16, an adjustment block 14 is inserted and fixedly connected to the top of the transition portion 15, and the adjustment block 14 is inserted and extended to the top of the outer wall of the first shell 11, and the adjustment block 14 is twisted to make the transition portion 15 flip along the semicircular surface, thereby forming a block for one of the two through holes 13, thereby completing the diversion control of the flue gas.

[0016] A third rotating shaft 23 is inserted and rotatably connected on both sides of the inner wall of the collecting box 6, and both ends of the third rotating shaft 23 pass through and extend to the outside of the collecting box 6. A baffle 22 is provided on the side where two adjacent third rotating shafts 23 are close to each other. The baffle 22 can be used to close the interior of the collecting box 6 to prevent leakage of high-temperature flue gas. The baffle 22 can be flipped by rotating the third rotating shaft 23, so that the dust falls from the discharge hole 7 to complete the collection of the dust.

[0017] A matching gear 28 is inserted and rotatably connected between the two collection boxes 6 through a fixed plate and an axis, a bevel gear set 26 is set between the axis for fixing the matching gear 28 and the first rotating shaft 16, and a second flip pinion 30 is fixedly connected to one end of the third rotating shaft 23. A first flip large gear 24 and a second flip large gear 25 are respectively inserted and rotatably connected to one side of the collection box 6 through a pair of axes, and the first flip small gear 29 is fixedly connected to the axes on the first flip large gear 24 and the second flip large gear 25, and the first flip small gear 29 is meshed with the second flip small gear 30, and the second flip large gear 25 is meshed with the first flip large gear 24, and the second flip large gear 25 on one of the collection boxes 6 is meshed with the matching gear 28, and the axis for fixing the matching gear 28 and the axis for rotating the second flip large gear A pulley group 27 is arranged between the shafts 25 fixed on the other collection box 6, the first rotating shaft 16 is arranged in two sections, and a conversion part 8 is arranged between the two first rotating shafts 16, the conversion part 8 is composed of a plurality of gears, a synchronous wheel and a synchronous belt. By setting the conversion part 8, the rotation direction of the adjustment block 14 can be converted, and through the rotation cooperation of the bevel gear group 26, the second flip large gear 25, the first flip large gear 24, the second flip small gear 30 and the first flip small gear 29, the adjustment block 14 can be turned to drive the two third rotating shafts 23 to rotate toward each other, thereby completing the automatic flipping and closing of the baffle 22. It should be noted that the baffles 22 inside the two collection boxes 6 are in an asynchronous state, that is, one group of baffles 22 is closed and the other group of baffles 22 is in a flipped state, so twisting the adjustment block 14 can synchronously switch the flipping and closing states between the two groups of baffles 22.

[0018] One end of the third rotating shaft 23 is fixedly connected to a driving pulley 9, and the end of the second rotating shaft 21 is fixedly connected to a driven pulley 10, and a belt is tensioned between the driven pulley 10 and the driving pulley 9. Through this arrangement, when the third rotating shaft 23 is rotated, the two second rotating shafts 21 can be driven to rotate synchronously, which also drives the multiple filter plates 17 to flip synchronously, tilt them, and thus better make them drop the dust attached to them.

[0019] A pair of protrusions 32 are provided on the top of the sealing plate 3, and a pressing block 33 is inserted and slidably connected inside the protrusion 32. The end of the pressing block 33 is fixedly connected to a pressing plate 31, and a return spring 34 is fixedly connected between the pressing plate 31 and the inner wall of the protrusion 32. Through this arrangement, continuous pressing of the pressing block 33 can make the pressing plate 31 continuously contact the first fixed plate 18, thereby vibrating the filter plate 17 and causing the dust contained thereon to fall off.

[0020] Evenly distributed spring pieces 19 are fixedly connected between the first fixing plate 18 and the second fixing plate 20 . This arrangement greatly increases the vibration amplitude of the first fixing plate 18 , thereby improving the cleaning efficiency of the dust on the filter plate 17 .

[0021] Working principle: After the smoke enters the part 2 for diversion, it is filtered through one of the filter components, while the other filter component is in an idle state. At this time, the filter plate 17 through which the high-temperature smoke passes is arranged in parallel, and the baffle 22 corresponding thereto is in a closed state, while the filter plate 17 and the baffle 22 in the idle state are both in an inclined state. At this time, the filter plate 17 can be vibrated by continuously pressing the pressing block 33 to clean up the attached dust, and the dust shaken off at the bottom of the discharge hole 7 can be collected centrally, and the states of the two sides can be switched by turning the adjusting block 14.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
