[0032] Example two

[0033] Please refer to Figure 5 , and on the basis of example one, a anti-blocking mechanism 8 is further obtained.

[0036] The worm 84 is engaged with the worm wheel 85.

[0037] In actual operation, when the device is used, the air inlet pipe 715 is connected with the external ventilation component, and then the material is injected into the fluidized bed vertical cylinder 1 through the feeding cylinder 3, and the material falls in the fluidized bed vertical cylinder 1 until it falls into the flow resistance plate 6 and is stacked on the flow resistance plate 6.

[0038] When the material is solidified, the second motor 83 is started to drive the worm 84, and since the worm 84 is engaged with the worm gear 85, the rotation of the worm 84 drives the worm gear 85 to rotate, so that the fan roller 81 rotates in the discharge cylinder 4. Through the rotation of the fan roller 81, the solidified material can be discharged from the discharge cylinder 4 without blocking. During the discharging process of the solidified material, the gas flow continues to blow in the fluidized bed vertical cylinder 1, which can prevent the material from remaining on the flow resistance plate 6.
