Abstract
The utility model relates to a gravity type negative pressure discharging device for drying equipment. The gravity type negative pressure discharging device comprises a shell body communicated vertically, a rotating shaft, a discharging valve plate, a screw rod and a balance weight, wherein the rotating shaft is arranged on one side of a discharge port in the top of the shell body, the discharging valve plate is fixed on the rotating shaft and is used for sealing the bottom of the discharge port, the screw rod is vertically and fixedly connected to the rotating shaft, and the balance weight is arranged on the screw rod. When the discharging valve plate seals the discharge port, the included angle between the discharging valve plate and the vertical line is between 50 degrees and 70 degrees. The lower portion of a discharge port in the bottom of the shell body is connected with a negative pressure material absorbing device. The negative pressure material absorbing device comprises a hopper and a high pressure cooling air hose, wherein the hopper is connected to the lower portion of the discharge port in the bottom of the shell body, and the high pressure cooling air hose is connected to the bottom of the hopper. When the negative pressure material absorbing device works, the negative pressure produced by the negative pressure material absorbing device absorbs the discharging valve plate downwards to enable the discharging valve plate to be opened by a certain angle. The angle can be adjusted by adjusting the position of the balance weight on the screw rod, and the discharging speed is accurately controlled. The gravity type negative pressure discharging device is simple in structure and convenient to use.
