When the suction fan 140 draws air, a negative pressure is formed in the drying drum 110, so that the hot air in the housing of the heater 130 enters the drying drum 110 and is discharged through the suction fan 140. In order to prevent the goods from falling into the first duct or the second duct 162, an end of the first duct connected to the fan 140 is inclined upward, and an end of the second duct 162 connected to the heater 130 is inclined upward. In addition, a filter screen 170 is disposed on the first duct to intercept the cargo powder in the hot wind.
In order to feed the drying cylinder 110, a feeding hopper 150 is further disposed on the top plate of the drying cylinder 110, and a sealing cover is disposed at a feeding port of the feeding hopper 150. In order to facilitate discharging, a discharging opening is formed in the bottom plate 111, and the drying cylinder 110 further includes a discharging door rotatably connected to the bottom plate 111 for opening or closing the discharging opening.
The automatic discharging device further comprises a discharging control device, wherein the discharging control device comprises a control motor 191, a crank 192 and a connecting rod 193, the crank 192 is hinged with the supporting frame 180, one end of the connecting rod 193 is hinged with the crank 192, and the other end of the connecting rod 193 is hinged with a discharging door; the control motor 191 is arranged on the support frame 180 and is in transmission connection with the crank 192. Crank 192, connecting rod 193, discharge door and support frame 180 constitute a crank 192 rocker mechanism, and when crank 192 rotates, the discharge door swings, thereby realizing opening and closing. The control motor 191 is in transmission connection with the pivot shaft of the crank 192 through a worm gear reducer.
