Abstract
Improved coke chute systems (100) include a lock (130) that receives and automatically secures a coke-receiving conduit (110) to a coke vessel after the lock (130) is switched to a closed position. Contemplated systems may further be combined with a horizontally movable coke chute cover, or a cover that is moved by an actuator (114) that lifts and rotates the cover from a first position to a second position.
Claims15
A coke chute system comprising:
- a coke chute coupled to an actuator that moves the coke chute between a lowered first position and a raised second position, wherein the coke chute is further coupled to a contactor;
- a lock with a latch having an open position and a closed position and coupled to a coke vessel;
- wherein the contactor engages with the latch in the closed position and automatically secures the coke chute relative to the coke vessel as the coke chute moves from the first position to the second position;
- and
- wherein the contactor disengages the latch in the opened position.
2 more elements
A coke chute cover comprising:
- a frame and a coke chute cover coupled to the frame, wherein the coke chute cover is a structure other than a coke vessel bottom head;
- a wheel coupled to the frame, wherein the frame further comprises a guide element, and a bracket coupled to an actuator that moves the frame between a first position and a second position;
- and
- wherein the wheel and the guide element move along a rail, and wherein the coke chute cover covers at least part of a flow path of coke between a coke vessel outlet and a coke chute when the frame is in the first position.
1 more element
A pivoting coke chute cover comprising:
- a coke chute cover from which extend a first extension and a second extension, wherein the first extension is coupled to an actuator that lifts and rotates the coke chute cover between a first position and a second position, and wherein the second extension is coupled to a wheel;
- and
- wherein the coke chute cover covers at least part of a flow path of coke between a coke vessel outlet and a coke chute when the cover is in the first position.
