Has two fixed casters 2 and two free casters 3 with a brake attached thereto, and is movable. A closed container body 4 for accommodating powder particles is fixed to the gantry 1, and the container body 4 has a cylindrical lower end and an eccentric frustoconical shape with an upper end lower than this. It is made in outline. A porous plate 5 having air permeability is installed at the lower end portion of the container body 4, that is, a cylindrical portion.
The inside of the container body 4 is divided into upper and lower parts by
A pressure chamber 6 is formed below the porous plate 5. The container main body 4 is provided with a vertical discharge pipe 7 penetrating the ceiling wall 4a, and the lower end of the vertical discharge pipe 7 is located slightly above the center of the perforated plate 5. The vertical discharge pipe 7 is fixed to the top wall 4a of the container body 4 via a flange 8, a ball valve 9 is provided at the upper end of the vertical discharge pipe 7, and a booster 10 is provided above it. The coupler 11 such as a connection flange is attached to the upper end.
The top wall 4a of the container body 4 has a powder / granule input port 12 formed at a position apart from the penetrating portion of the vertical discharge pipe 7, and the powder / granule input port 12 is closed by an openable / closable lid 13. ing. On the gantry 1, a coupler 15 is connected to one end and an air feeding pipe 16 having the other end opened to the pressurizing chamber 6 is attached. The air feeding pipe 16 has a ball valve 17 extending from one end to the other end. A mist separator 18, a pressure reducing valve 19, a branch joint 20, a needle valve 21, a flow meter 22, and a diaphragm valve 23 with a solenoid valve are interposed in this order. The branch joint 20 mounted on the pneumatic pipe 16 and the booster 10 mounted on the vertical discharge pipe 7 are connected by an auxiliary pneumatic pipe 25. The auxiliary pneumatic pipe 25 has a needle valve 26 and a ball valve. 27 and a check valve 28 are interposed. A pressure gauge 29 for measuring and displaying the pressure in the pressurizing chamber 6 is further attached to the gantry 1. The coupler 15 attached to the upper end of the vertical discharge pipe 7 is connected to the vertical transport pipe 31 for supplying powder particles to the separator (not shown), and the coupler 15 attached to one end of the pneumatic pipe 16 is It is connected to a pressurized gas supply pipe 32 including a hose connected to an external pressurized gas supply source.

Next, the operation will be described. First, the lid body 13 is opened at the pouring position of the granular material, and the granular material is charged into the container body 4. Then, the lid 13 is closed, and the gantry 1 is moved to the vertical air feeding position of the powder and granules, and the coupler 11 at the upper end of the vertical discharge pipe 7 is moved.
Is connected to the vertical transport pipe 31, and the coupler 15 at one end of the pneumatic pipe 16 is connected to the pressurized gas supply pipe 32. As a result, a transportation gas such as compressed air is supplied to the pneumatic tube 16, the transportation gas is depressurized to a predetermined pressure by the pressure reducing valve 19, and further adjusted to a predetermined flow rate by the needle valve 21. Then, the diaphragm valve 23 is set to 1 by the control signal supplied to the solenoid valve.
The gas for transportation is supplied in a pulsed manner to the pressurizing chamber 6 by opening and closing in a predetermined cycle of about a second. As a result, the pulsing transport gas passes through the porous plate 5 and pushes the powder particles into the vertical discharge pipe 7. By this operation, a layer of powder particles and a layer of transport gas are alternately formed inside the vertical discharge pipe 7 in order from the bottom, and these layers gradually grow upward, so that powder particles are formed by so-called plug transport. Body 4 with container for transportation
Is supplied to the separator through the vertical discharge pipe 7 and the vertical transport pipe 31. In addition, a part of the transport gas is used in the branch joint 2
0 is supplied from the booster 10 to the vertical discharge pipe 7 through the auxiliary pneumatic pipe 25, and it is possible to assist the vertical pneumatic transport of the powder and granules. Further, during transportation, blockage occurred in the vertical transport pipe 31. Sometimes the ball valve 9 is closed and the booster 10

Since the needle valve 21 and the diaphragm valve 23 are interposed, the gantry 1 is moved to the vertical air feeding position, the coupler 11 connects the vertical discharge pipe 7 to the vertical transportation pipe 31, and the coupler 15 adds the air feeding pipe 16. By connecting to the pressurized gas supply pipe 32, powder particles can be fed vertically.
The versatility is high, for example, one vertical pneumatic container can be used for plural vertical pneumatic transportations. In addition, the flowmeter 22 on the gantry 1
Since the pressure gauge 29 and the pressure gauge 29 are installed, the pressure and flow rate of the transport gas can be known and can be appropriately adjusted. Further, since the outer shape of the container body 4 has a truncated conical shape except for the lower end portion, the area of the ceiling wall 4a is large, so that the top wall 4a of the container body 4 is separated from the penetrating portion of the vertical discharge pipe 7. It is possible to form the powder / granule input port 12 at a different position, and further, to form the powder / granule input port 12 having a sufficient size without increasing the height of the powder / granule input port 12, and at the same time, the container The amount of powder or granules accommodated can be increased as compared with the case where the main body 4 is cylindrical. Further, since the lower end portion of the container body 4 is formed into a cylindrical shape, the amount of the powder or granular material remaining in the container body 4 after the completion of vertical pneumatic feeding can be favorably reduced.

(Other Embodiments) In the above embodiments, the outer shape of the container body 4 is formed into an eccentric truncated cone shape with the lower recess excluding the lower end portion, but the present invention is limited to such a configuration. However, as shown in phantom lines in FIG. 2, for example, the truncated cone-shaped portion may be configured without eccentricity.

Further, since the display device is provided in the air feeding pipe, it is possible to know the pressure and flow rate of the transport gas, and to adjust them appropriately. In addition, the outer shape of the container body is a truncated cone shape except for the lower end, so the area of the ceiling wall is large. It is possible to form a granular material input port, and it is possible to form a sufficient granular material input port without increasing the height of the granular material input port, and at the same time, rather than making the container body cylindrical. It is possible to increase the storage capacity of powder and granules. Further, since the lower end portion of the container body is formed in a cylindrical shape, the amount of powder or granular material remaining in the container body after the completion of vertical pneumatic feeding can be favorably reduced.
