[0027] In practice, hot air is provided by boilers, combustion rooms, etc.
[0028] Reference Figure 1The drum 100 is relatively long, so as to be suitable for re-drying the feed particles after a certain period of time. The drum 100 is supported by at least two sets of supporting wheels 110, and the drum 100 is fixedly connected with a gear ring 120 surrounding its outer peripheral wall, and the gear ring 120 is suitable for connecting to a motor through a corresponding gear transmission, and the motor can be a hydraulic motor or an electric motor, and the drum 100 is driven to roll by the motor.
[0029] Better yet, the upper end of the feed stand 210 is connected to a feed funnel, which is suitable for dropping materials into the tip of the waterfall cone 220.
[0030] Reference Figure 2 , the flow direction of feed particles V 料 , hot air flow direction V 风 . Reference Figure 1 and Figure 2 , the operation process of the utility model is as follows:
[0031] Feeding: shoveling / pouring feed particles into the upper end of the feed vertical cylinder 210 so that the feed particles hit the peripheral wall of the waterfall cone 220;
[0032] The feed particles dispersed by the waterfall cone 220 collide with the hot air in the rolling and / or waterfall flow, and the relatively dispersed feed particles are fully exposed to the hot air and quickly heated, and then dried and shaped, which greatly reduces the amount of feed particles sticking together;
[0033] The shaped feed particles falling from the feed vertical cylinder 210 are then smashed toward the feed end of the drum 100 or the guide cone 310 to further disperse the feed particles.
[0034] Re-drying: the feed particles placed in the drum 100 are tumbled, moved leftward, and re-dried in the hot inner chamber of the drum 100 based on the tilting and rolling of the drum 100. The re-dried feed particles flow out from the discharge end of the drum 100.
[0035] Compared with the prior art, the beneficial effects of the present application include: the feed particles are first in a tumbling and waterfall-like divergent form, fully contacting the hot air, effectively initially drying, so that the feed particles are quickly shaped, and the amount of feed particles sticking together is greatly reduced; the feed particles are in a divergent form and fully contacting the hot air, quickly absorbing the exhaust heat of the dryer, so that the heat of the hot air is fully utilized; the waterfall cone 220 blocks the overflow diameter of the hot air to a certain extent, avoiding the rapid loss of hot air from the drum 100, and improving the drying effect of the drum 100.
