Abstract
A flow rate adjustment device includes: an adjustment unit including a pipe and a sealing plate provided below an outlet of the pipe, the sealing plate having a sealing surface; and a moving unit that moves the sealing plate to a sealing position where the sealing surface of the sealing plate is positioned vertically below the outlet of the pipe and a retraction position where the sealing surface of the sealing plate is retracted from a point vertically below the outlet of the pipe.

A flow rate adjustment device comprising:
- an adjustment unit including a pipe and a sealing plate provided below an outlet of the pipe, the sealing plate having a sealing surface;
- and
- a moving unit that moves the sealing plate to a sealing position where the sealing surface of the sealing plate is positioned vertically below the outlet of the pipe and a retraction position where the sealing surface of the sealing plate is retracted from a point vertically below the outlet of the pipe, the moving unit including an actuator,
- wherein
- when the sealing plate is moved from the retraction position to the sealing position by the moving unit, falling of solid particles downward from the outlet is stopped because the outlet is sealed by the solid particles deposited on the sealing surface, and
- when the sealing plate is moved from the sealing position to the retraction position by the moving unit, falling of the solid particles through the outlet is initiated because the solid particles deposited on the sealing surface fall off and sealing of the outlet by the solid particles is released.
