after the drying operation and the cooling operation are carried out for 0.5-2 hours at the same time, the linear expansion mechanism is driven to retract the partition door, the first motor is driven to drive the first conveying mechanism to move, the second motor is driven to drive the second conveying mechanism to move, and the third motor is driven to drive the third conveying mechanism to move at the same time, so that the cooled smoke and fire on the third conveying mechanism are blanked, and the dried smoke and fire on the second conveying mechanism are transferred to the third conveying mechanism; and transferring the new firework to be dried on the first conveying mechanism to the second conveying mechanism, and circulating the firework.
3. The control method according to claim 2, wherein the rotation speeds of the first motor, the second motor, and the third motor are the same.
4. The control method according to claim 2, wherein sensing devices are provided at both ends of the drying chamber, the control method further comprising:
and receiving a signal of the sensing device, and stopping the drying fan when detecting that the two ends of the drying chamber are not sealed.
5. The control method according to claim 2, wherein the partition sealing device comprises a partition frame, the linear expansion mechanism is disposed at the top or the bottom of the partition frame, the partition door is slidably mounted on the partition frame in a height direction of the drying chamber, and the partition door is parallel to a width direction of the second conveying mechanism.
6. The control method according to claim 5, wherein an opening is provided in a side wall of the partition frame in a longitudinal direction of the second conveying mechanism, and the conveyor belt penetrates through the opening.
7. The control method according to claim 2, wherein the third conveyance mechanism is a belt conveyance mechanism having an upper conveyance area and a lower return area formed thereon; the cooling chamber further comprises a cleaning device, the cleaning device comprises at least one water inlet pipe and a plurality of water outlet pipes communicated with the water inlet pipes, the water inlet pipes are arranged along the transmission direction of the third conveying mechanism, and the water outlet pipes extend out of the upper part and/or the lower part of the lower return area; a plurality of water outlets are formed in one side, facing the lower return area, of the water outlet pipe; the control method further comprises the following steps:
and when the firework dryer stops working, the cleaning device is started to clean the cooling chamber.
8. The control method according to claim 7, wherein the number of the water inlet pipes is 2, and the control method comprises a first water inlet pipe and a second water inlet pipe, wherein the first water inlet pipe is arranged between the upper transportation area and the lower return area, and the water outlet pipe communicated with the first water inlet pipe is positioned above the lower return area; the second water inlet pipe is arranged below the lower return area, and the water outlet pipe communicated with the second water inlet pipe is positioned below the lower return area.
