Abstract

A system is disclosed for automatically removing the cover of a chute beneath a coke drum. The system operates in conjunction with a remotely operable coke deheading device so that the chute cover is removed when the coke drum is deheaded. Also disclosed is a method for facilitating coke removal from a coke drum into a coke chute where the chute cover is automatically removed upon activation of the coke drum deheading device.

Claims

1. An automatic apparatus for removing the cover of a receiver for receiving material from a drum with an opening fitted with a head associated with a remotely operable deheading device, comprising:

a cover which functions to cover an opening of the receiver;

said cover provided with at least one flexor which allows said cover to bend;

connectors with pivots for attaching said cover to extendable legs, wherein said connectors with pivots function to accommodate changes in position of the cover by movement of said flexor and said legs; and

connectors for attaching said extendable legs to the head of said drum, such that said legs retract and said flexor flexes the cover such that the cover can be lifted and moved away from the opening of the receiver as said head is moved away from the opening of the drum by the deheading device so material may fall from the drum into the receiver.

2. The apparatus of claim 1 wherein said cover has a flexor for reducing the horizontal width of said cover and wherein the system further comprises a stop for effecting the angle of flexion of said cover.

3. The apparatus of claim 2 wherein said flexor is a hinge.

4. The apparatus of claim 1 wherein said legs are telescopic.

5. The apparatus of claim 1 wherein said drum is a coke drum.

6. The apparatus of claim 1 wherein said receiver is a chute.

7. The apparatus of claim 1 wherein said legs extend and said flexor straightens to return the cover to the receiver.
