The collecting mechanism includes a connecting pipe 10 sleeved on the upper side of the second bevel gear 4, a collecting box 14 connected to the upper side of the connecting pipe 10, a third filter plate 15 slidably connected to the inner side of the collecting box 14, a suction fan 19 fixedly installed on the right bottom of the collecting box 14, and a mixing mechanism arranged on the upper side of the collecting box 14. The mixing mechanism includes a second water pump 13 fixedly installed on the upper left end of the collecting box 14, a drainage pipe 17 connected to the right side of the second water pump 13, a plurality of atomizing nozzles 18 fixedly connected to the surface of the drainage pipe 17 and a water tank 11 connected to the left side of the second water pump 13.

[0030] Among them, a socket assembly for socketing the upper side of the second bevel gear 4 is provided on the lower side of the connecting pipe 10, and the socket assembly includes a bearing 6 socketed on the outer wall of the lower side of the connecting pipe 10, and the outer wall of the lower side of the bearing 6 is socketed on the inner wall surface of the second bevel gear 4. A plurality of through holes 16 are opened on the surface of the cleaning brush 7, and the plurality of through holes 16 are arranged equidistantly laterally. The right side of the water tank 11 is fixedly connected to the left surface of the exhaust gas exhaust pipe 1, and a cover door is hinged on the front end face of the exhaust gas exhaust pipe 1. The water suction end of the second water pump 13 is connected to the water tank 11, and the drainage end of the second water pump 13 is connected to the drainage pipe 17 inside the collecting box 14.

[0031] Embodiment 2:

[0032] See also Figure 1-3 On the basis of the first embodiment, it includes a first water pump 12 connected to the lower side of the water tank 11, the front end surface of the first water pump 12 is connected to the collecting box 14, the water suction end of the first water pump 12 is connected to the bottom of the collecting box 14, and the drainage end of the first water pump 12 is connected to the bottom of the water tank 11.

[0035] The waste gas generated during the production of furfural is discharged upward from the waste gas exhaust pipe 1 and filtered through the first filter plate 8 and the second filter plate 9. When cleaning, it is only necessary to start the driving motor 2 to drive the first bevel gear 3 to mesh with the second bevel gear 4 to synchronously rotate the two cleaning brushes 7 on the outside of the rotating shaft 5 to rotate and clean the filtering surfaces of the first filter plate 8 and the second filter plate 9 respectively. It is also necessary to start during the cleaning period. The suction fan 19 rotates and cooperates with the through hole 16 opened on the upper side of the cleaning brush 7 to absorb the cleaning objects dropped from the first filter plate 8 and the second filter plate 9 and discharge them into the collection box 14. At this time, the second water pump 13 is started to spray the water in the absorption water tank 11 from the atomizing nozzle 18. The mist and the cleaning objects are combined and naturally fall on the upper side of the third filter plate 15, and then filtered by the third filter plate 15 to naturally fall downward and separate. As the bottom of the collection box 14 is inclined, it accumulates to the left, and then the first water pump 12 is used again to absorb and discharge the filtered water into the water tank 11 to achieve the reuse of the water.
