A closure device for a bulk material system is provided, specifically for regulating a flow of heat transfer particles. The closure device includes a bulk material guide which has a first opening for connection to the bulk material system and a second opening for the discharge of a bulk material guided by the bulk material system, and a closure blade which is rotatably mounted about an axis of rotation. The closure blade, in a first rotational position, closes the second opening and, in a second rotational position, at least partially uncovers the second opening. The closure blade is mounted in such a manner to reduce jamming of the closure device in operation.

Abrégé

The invention relates to a closure device for a bulk materials system and to the use of such a closure device for regulating a heat transfer particle flow. The closure device has a bulk materials guide formed as a hollow body having a first opening for connection to the bulk materials system and a second opening for discharging a bulk material guided by the bulk materials system, and a closure blade which is rotatably mounted about an axis of rotation, which closes the second opening in a first rotary position and at least partly opens the second opening in a second rotary position. The closure blade is supported in such a way that, when the closure blade rotates about the axis of rotation to transfer from the first to the second rotary position, a first point on a first edge of the closure blade, which is located furthest forward in relation to the direction of movement, moves on a first movement curve, and a second point on the closure blade, which is located physically after the first point in relation to the direction of movement, moves on a second movement curve which, at least in some sections, is at a greater distance from the axis of rotation than the first movement curve. During the movement on the first and second curved path, the first and second point each have a movement component located tangentially relative to the closure blade.
