US4213489A — One-spot coke quench car coke distribution system

Claim 1

Independent Claim 322 words

A one-spot coke quench car comprising: (a) a wheel-mounted frame; (b) a receptacle mounted to said frame into which incandescent coke is pushed from a coke oven; (c) at least one water metering storage chamber means, for containing a predetermined volume of water under pressure, juxtaposed to said receptacle, comprising: (1) an upper frusto-conical portion open at both ends, (2) a lower frusto-conical portion open at both ends, fixed to said upper frusto-conical portion such that the larger diameters of said upper frusto-conical end portion and said lower frusto-conical end portion abut at the point of fixation to form a chamber having a central axis passing through the open smaller diameters of said upper frusto-conical portion and said lower frusto-conical portion; (3) a valve disc positioned perpendicular to said central axis and disposed to seal the open smaller diameter of said lower frusto-conical portion; (4) a valve stem, fixed to said valve disc, projecting through the open smaller diameter of said upper frusto-conical portion coaxial to said central axis; (5) a packing gland sealing said smaller diameter of said upper frusto-conical portion around said stem such that said valve stem protrudes through said packing gland; and (6) inlet means through which water can enter said water metering storage chamber. (d) pressurization means by which said predetermined volume is conveyed into said water metering storage chamber means and pressurized therein; (e) discharge means by which said predetermined volume is released from said water meter storage chamber means; (f) conduit means by which said predetermined volume is conveyed, after release, into the center core of said incandescent coke within said receptacle; and (g) dispersement means by which said predetermined volume is brought from said conduit means into direct contact with said center core of said incandescent coke within said receptacle, whereat said predetermined volume is rapidly and explosively converted into steam to disrupt and redistribute said incandescent coke within said receptacle prior to quenching.

Claim 2

Dependent Claim 322 words

A one-spot coke quench car comprising: (a) a wheel-mounted frame; (b) a receptacle mounted to said frame into which incandescent coke is pushed from a coke oven; (c) at least one water metering storage chamber means, for containing a predetermined volume of water under pressure, juxtaposed to said receptacle, comprising: (1) an upper frusto-conical portion open at both ends, (2) a lower frusto-conical portion open at both ends, fixed to said upper frusto-conical portion such that the larger diameters of said upper frusto-conical end portion and said lower frusto-conical end portion abut at the point of fixation to form a chamber having a central axis passing through the open smaller diameters of said upper frusto-conical portion and said lower frusto-conical portion; (3) a valve disc positioned perpendicular to said central axis and disposed to seal the open smaller diameter of said lower frusto-conical portion; (4) a valve stem, fixed to said valve disc, projecting through the open smaller diameter of said upper frusto-conical portion coaxial to said central axis; (5) a packing gland sealing said smaller diameter of said upper frusto-conical portion around said stem such that said valve stem protrudes through said packing gland; and (6) inlet means through which water can enter said water metering storage chamber. (d) pressurization means by which said predetermined volume is conveyed into said water metering storage chamber means and pressurized therein; (e) discharge means by which said predetermined volume is released from said water meter storage chamber means; (f) conduit means by which said predetermined volume is conveyed, after release, into the center core of said incandescent coke within said receptacle; and (g) dispersement means by which said predetermined volume is brought from said conduit means into direct contact with said center core of said incandescent coke within said receptacle, whereat said predetermined volume is rapidly and explosively converted into steam to disrupt and redistribute said incandescent coke within said receptacle prior to quenching.

Claim 3

Dependent Claim 75 words

A one-spot coke quench car as set forth in claim 1 wherein: (a) said conduit means is a pipe, connected at one end to said smaller diameter of said lower frusto-conical portion, running through the central core of said incandescent coke within said quench car, and (b) said dispersement means is a transverse tube intersecting said pipe at said central core and having open ends through which said water is directed to said incandescent coke.

Claim 4

Dependent Claim 41 words

A one-spot coke quench car as set forth in claim 1 wherein: (a) said pressurization means comprises a pump connected to said inlet means by piping; and (b) said discharge means comprises an actuating means operable to reciprocate said valve stem.

Claim 5

Dependent Claim 59 words

A one-spot coke quench car as set forth in claim 3 further comprising: (a) a pressure relief valve interposed in said piping between said pump and said water metering chamber by which excess pressure within said water metering chamber can be released; and (b) a return line connected to said pressure relief valve to bleed off said released pressure.
