Abstract
In one or more arrangements, a system is presented for preventing the spread of fire through a conveyor opening in a fire wall. In one or more arrangements, a fire door system is connected to the fire wall and/or conveyor proximate to the conveyor opening. The fire door system includes a door assembly, a door frame assembly, and an actuator. The door frame assembly is connected to the fire wall, covers portions of the opening below the conveyor and between belts of the conveyor, and forms a door opening above the conveyor. The door assembly is configured to move between a closed position, where door assembly covers the door opening, and an open position, where the door assembly at least partially uncovers the door opening. The actuator is configured to cause the door to be moved to the closed position in response to fire.

A system, comprising:
- a conveyor;
- the conveyor having a set of rollers;
- the conveyor having a belt;
- wherein the belt is positioned on the set of rollers and forms a continuous loop having an upper portion of the belt and a lower portion of the belt;
- wherein the conveyor extends through a first opening in a fire wall;
- wherein the belt partitions the first opening into an upper opening positioned above the upper portion of the belt, a middle opening positioned between the upper portion of the belt and the lower portion of the belt, and a lower opening positioned below the lower portion of the belt;
- a fire door system;
- wherein the fire door system includes a door assembly;
- wherein the fire door system includes a door frame assembly;
- wherein the door frame assembly is connected to the fire wall, covers a lower opening, covers the middle opening, and forms a frame for the door assembly having a door opening within the upper opening of the fire wall;
- wherein the door assembly is configured to move between a closed position and an open position;
- wherein in the closed position the door assembly covers the door opening;
- wherein in the open position the door assembly at least partially uncovers the door opening;
- and
- wherein the fire door system includes an actuator configured to cause the door to be moved from the open position to the closed position in response to occurrence of fire.
A fire door system for a conveyor extending through an opening in a fire wall, comprising:
- wherein a belt of the conveyor partitions the opening into an upper opening positioned above an upper portion of the belt, a middle opening positioned between the upper portion of the belt and a lower portion of the belt, and a lower opening positioned below the lower portion of the belt;
- a door assembly;
- a door frame assembly;
- wherein the door frame assembly is connected to the fire wall, covers a lower opening, covers the middle opening, and forms a frame for the door assembly having a door opening within the upper opening of the fire wall;
- wherein the door assembly is configured to move between a closed position and an open position;
- wherein in the closed position the door assembly covers the door opening;
- wherein in the open position the door assembly at least partially uncovers the door opening;
- and
- an actuator configured to cause the door to be moved from the open position to the closed position in response to occurrence of fire;
- and
- wherein the actuator is configured to hold the door in the open position in absence of fire.
