From the state where b is stopped at the standby position C, as shown in FIG. 3A, one pusher 3 a is moved to the retracted position A. As a result, the object G to be processed such as dust is supplied from the hopper 2 into the one passage 8a, and then the one pusher 3a is moved to the forward movement position B as shown by the phantom line in FIG. As a result, the object G to be processed such as dust is pressed and pushed into the compression portion 5, and the object G to be treated such as dust that remains in the compaction portion 4 is extruded from the extrusion port 1a into the furnace 7. Supplied. Subsequently, as shown in FIG. 3B, one pusher 3a is moved to the standby position C and stopped. Next, as shown in FIG. 7C, the other pusher 3b is moved to the retracted position A and then to the advanced position B by the same procedure. As a result, the object G to be processed such as dust is pressed and pushed into the compression portion 5, and the object G to be treated such as dust that remains in the compaction portion 4 is extruded from the extrusion port 1a into the furnace 7. Supplied. Then, as shown in FIG. 3D, the other pusher 3b may be moved to the standby position C and stopped. By repeating the above operation in a predetermined time cycle, the object G to be treated such as dust can be extruded and supplied into the furnace 7.

ができる。Here, even if the object G to be treated such as dust has a high fluidity such as a high water content powder fluid (for example, sludge or slurry), as shown by the phantom line in FIG. When the pusher 3a is moving forward, the other pusher 3b closes half of the communication port 1b at the standby position C. Therefore, the processing object G such as dust pushed by the forward movement of the one pusher 3a G Enters into the gap between the other pusher 3b and the consolidation section 4 and hardly flows back to the hopper 2 side, and the other pusher 3b is moving forward as shown by the phantom line in FIG. 3 (c). At this time, since the one pusher 3a closes half of the communication port 1b at the standby position C, the object to be processed G such as dust hardly flows backward to the hopper 2 side as in the above case. Therefore,
Even the object G having a high fluidity such as dust can be reliably extruded and supplied from the extrusion port 1a of the cylinder 1 to the outside in a fixed amount.
