[0021] 1. For this multifunctional hopper of the fluidized bed furnace, during use, start the first motor to drive the second rotating shaft to rotate. The rotation of the second rotating shaft will drive the first bevel gear to rotate. When the first bevel gear rotates, it will drive the second bevel gear to rotate. The rotation of the second bevel gear will drive one of the gears to rotate. Since the two gears are meshed, when one of the gears rotates, the other gear will also rotate. When the two gears rotate, the two first rotating shafts will also rotate accordingly. When the two first rotating shafts rotate, the multiple stirring rollers on the outer side walls of the two first rotating shafts will also rotate. At this time, pour the raw materials into the hopper. When the raw materials pass through the multiple stirring rollers, they will be fully stirred and mixed.

Moreover, when the sieve plate slides reciprocally, the raw materials passing through the sieve plate will be discharged from the bottom of the hopper in a wider range, which can not only remove impurities, but also make the raw materials distributed more widely when poured into the fluidized bed furnace, which has the advantage of convenience.

[0022] 2. When it is necessary to clean multiple stirring rollers of the multifunctional hopper of the fluidized bed furnace, start the second motor to drive the threaded rod to rotate. Since there are two sections of threads with opposite helix directions on the threaded rod, when the threaded rod rotates, the two threaded sleeves will slide in opposite directions. When the two threaded sleeves slide in opposite directions, the two brushes will follow and slide in opposite directions. When the two brushes slide in opposite directions, their spacing will be adjusted. When the two brushes slide to one side of the two first rotating shafts and abut against the multiple stirring rollers, drive the multiple stirring rollers to rotate according to the above operation, and the multiple stirring rollers can be cleaned by the two brushes. When it is necessary to remove the impurities on the top surface of the sieve plate, after pulling the movable plate outwards, the impurities on the top surface of the sieve plate can be removed through the second opening groove, which has the advantage of convenience.
