圧送式気力輸送装置。[Claims for Utility Model Registration] A sealable pressurized tank having an upper input section and a lower discharge section, a supply hopper provided in the input section of the tank for inputting powder and granules, and the supply hopper. A pressure-feeding pneumatic transportation device for powder and granular material, comprising a supply device for supplying powder and granular material, a transport pipe connected to the discharge part of the tank, and an air source for pumping the powder and granular material, the supply hopper and a first opening/closing device located between the supply device and for starting or stopping the supply operation of supplying powder and granular material to the supply hopper; A second opening/closing device for starting or stopping the supply operation to the pressurized tank, a pressure detector for detecting a pressure drop in the pressurized tank, and a second switch for detecting the upper limit of the powder and granular material level in the pressurized tank. Based on the detection operation of the two-level detector and the pressure detector, the operation of the air source is stopped and the supply operation of the second switchgear is started, and the supply operation of the second switchgear is started based on the detection operation of the second level detector. After stopping the supply operation of the switchgear, the supply operation of the second switchgear is stopped after a predetermined period of time, and the operation of the air source is started based on the stop of the supply operation of the second switchgear, and the supply operation of the first switchgear is started. 1. A pressure-feeding pneumatic transportation device for powder and granular material, characterized in that it is provided with a control device for starting operation.
