Abstract

Abstract A coke quenching car, movable along a battery of horizontal coke ovens, has a pair of spaced vertical walls extending transversely of the car and defining a fall space between them. The upper part of this space has a front opening for receiving coke from an oven. The space below the opening is closed by a front wall, while the back of the fall space is closed by a back wall. Extending from the bottom of the opening rearwardly in the fall space part way across the car is a ramp as wide as the fall space. A deck slopes from the back wall downwardly below the inner end of the ramp for receiving coke from it and discharging it beneath the ramp onto a floor that slopes from the front wall downwardly to the back wall. The lower part of the back wall has an outlet opening in it that normally is closed by a door. In the upper part of the fall space and also below the ramp and the deck there are water sprays for quenching coke beneath them.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 240 words
A coke quenching car movable along a battery of horizontal coke ovens for receiving coke discharged therefrom in a horizontal direction, comprising a pair of spaced vertical side walls extending transversely of the car and defining a fall space between them, the upper part of said space having a front opening between said vertical walls for receiving coke horizontally discharged from an oven, means for closing said opening, a fronT wall closing the front of the fall space below said opening, a back wall closing the back of said space, a ramp as wide as said fall space extending from the bottom of said opening rearwardly in said space part way across the car, a deck sloping from said back wall downwardly toward said front wall and below the inner end of said ramp for receiving coke therefrom and discharging it beneath the ramp, a floor sloping from said front wall downwardly toward said back wall for receiving coke from said deck and directing the coke toward said back wall beneath the deck, the lower part of said back wall having an outlet opening therein extending across said floor for escape of coke from the car, a door for said opening, a first water spray located above said fall space, a second water spray located below said ramp, and a third water spray located below said deck, each of said sprays being arranged for quenching coke passing beneath the sprays.
Claim 2
Dependent Claim 240 words
A coke quenching car movable along a battery of horizontal coke ovens for receiving coke discharged therefrom in a horizontal direction, comprising a pair of spaced vertical side walls extending transversely of the car and defining a fall space between them, the upper part of said space having a front opening between said vertical walls for receiving coke horizontally discharged from an oven, means for closing said opening, a fronT wall closing the front of the fall space below said opening, a back wall closing the back of said space, a ramp as wide as said fall space extending from the bottom of said opening rearwardly in said space part way across the car, a deck sloping from said back wall downwardly toward said front wall and below the inner end of said ramp for receiving coke therefrom and discharging it beneath the ramp, a floor sloping from said front wall downwardly toward said back wall for receiving coke from said deck and directing the coke toward said back wall beneath the deck, the lower part of said back wall having an outlet opening therein extending across said floor for escape of coke from the car, a door for said opening, a first water spray located above said fall space, a second water spray located below said ramp, and a third water spray located below said deck, each of said sprays being arranged for quenching coke passing beneath the sprays.
Claim 3
Dependent Claim 24 words
A coke quenching car according to claim 1, in which said ramp is provided with a central longitudinal ridge with laterally inclined side surfaces.
Claim 4
Dependent Claim 27 words
A coke quenching car according to claim 1, including temperature measuring means disposed in the fall space for regulating the quantity of water released by said sprays.
Claim 5
Dependent Claim 20 words
A coke quenching car according to claim 1, including a vapor cleaning chamber at the top of the fall space.
Claim 6
Dependent Claim 31 words
A coke quenching car according to claim 1, including walls diverging upwardly from the tops of said vertical walls, and water sprays disposed between the upper parts of said diverging walls.
Claim 7
Dependent Claim 74 words
A coke quenching car according to claim 1, in which said vertical walls are at the central portion of the car and are provided with openings beneath said deck, said sloping bottom wall extends laterally through said wall openings toward the opposite ends of the car, and said back wall extends laterally along said floor, whereby coke sliding down said sloping floor below said deck can spread out toward the ends of the car.
Claim 8
Dependent Claim 73 words
A coke quenching car according to claim 6, including a pair of front walls extending laterally from the front of said wall openings toward the ends of the car, end walls at the ends of the car connecting the back wall with said pair of front walls, and a roof at each side of said pair of vertical walls covering the space defined by the underlying back wall, end wall and front wall.
Claim 9
Dependent Claim 17 words
A coke quenching car according to claim 7, including pumps for said sprays mounted on said roofs.
