When the zinc powder is fully dried, an external container for containing the zinc powder is firstly placed under the equipment, then the rotating handle 413 is slid to enable the right end face of the fan-shaped sealing plate 411 to be attached to the limiting plate 22, and in the process, the rotating table 42 can synchronously rotate along with the rotation of the fan-shaped sealing plate 411 and the annular plate 412; at the same time, the slider at the upper end of the push rod 451 moves onto the inclined section in the trapezoidal groove of the turntable 42, thereby sliding the push rod 451 downward; the push rod 451 moves downwards and simultaneously drives the perforated circular plate 454 to move downwards synchronously, and meanwhile, the telescopic rod 54 stretches and drives the bottom plate 51 to rotate downwards by a certain angle, so that a discharging channel is formed below the drying chamber 34, and dried zinc powder can enter the lower external container through the discharging channel.
Working principle: s1: firstly, the zinc powder with drying is conveyed into each drying chamber 34 through the bin 21 and the material guide pipe 23, then the rotary handle 413 is slid to the center position of the guide groove 13, the fan-shaped sealing plate 411 is just above the first feeding hole, and a relatively closed cavity structure is formed in the drying chamber 34.
S2: starting an external hot air heater, and continuously introducing hot air into each drying chamber 34 through the central air pipe 31 and the L-shaped air guide pipe 33 to dry zinc powder; in this process, in order to prevent the pressure in the drying chamber 34 from being too high, hot air escapes through the air outlet holes on the fan-shaped sealing plate 411 after the zinc powder is dried; the microporous membrane arranged on the fan-shaped sealing plate 411 can keep air circulation, and meanwhile, zinc powder particles can be blocked in the drying chamber 34, so that the effects of purification and ventilation are achieved.
And S3, after the zinc powder is completely dried, the sliding rotary handle 413 enables the right end face of the fan-shaped sealing plate 411 to be attached to the limiting plate 22, in the process, the bottom plate 51 can rotate downwards by a certain angle under the action of the push-pull assembly 45, and then an opening is formed below the drying chamber 34, and the dried zinc powder falls into an external container below along the opening, so that drying is finished.
