Document Type and Number:
Japanese Patent JP2019007682
Kind Code:
A
Abstract:
To provide a sunlight introduction port opening/closing structure of a grain heating type solar heat reduction furnace capable of surely opening/closing a sunlight introduction port even in a narrow region.SOLUTION: Since a sunlight introduction port opening/closing structure of a grain heating type solar heat reduction furnace is composed of a plurality of diaphragm blades 7 configured to move an opening/closing structure, like a diaphragm of a camera, although each diaphragm blade 7 rotates only by a width dimension of itself with a rotational shaft 8 as a center, a sunlight introduction port A can be surely opened/closed only with the rotation. Accordingly, the sunlight introduction port opening/closing structure can be installed even in a narrow intermediate peripheral range B between the sunlight introduction port A and an outside peripheral range C.SELECTED DRAWING: Figure 3
