Claims

[Scope of utility model registration request]

(1) A transport pipe for transporting the powder and granular material supplied to the material supply hopper using compressed air from an air power source; an auxiliary pipe installed in parallel with this transport pipe for introducing compressed air from the air power source; A pressurizing nozzle installed in one or more stages in the middle of a transport pipe and pressurizing compressed air from the auxiliary conduit into the transport pipe via a corresponding branch pipe, and a corresponding pressurizing nozzle provided in the middle of each branch pipe. A pneumatic transportation device for powder and granular material, including a flow rate control valve that adjusts and controls the flow rate of compressed air to a pressurizing nozzle according to increases and decreases in the internal pressure of nearby transportation pipes.

(2) The pressurizing nozzle has either a front jet port that supplies compressed air in the direction of transport of the powder or a rear jet port that supplies compressed air in the opposite direction to the transport direction of the powder or granules. A pneumatic transportation device for powder or granular material according to claim (1) of the registered utility model.

(3) The pneumatic transportation device for powder and granular material according to claim (1), wherein the pressurizing nozzle has the front ejection port and the rear ejection port installed together.

(4) A filter pipe having a passage communicating with the transport path of the transport pipe is provided at an appropriate location of the transport pipe, and the filter pipe is covered and connected to an air power source to supply compressed air to the filter pipe. Pneumatic transportation of powder and granular material according to any one of claims (1) to (3) of the utility model registration claim, wherein a pressurized fluidized bed consisting of a sheath tube having an air supply section is detachably attached.
