Dust collector for a by-product coke oven

Claim 1

Dust collector apparatus for collecting the dust generated while pushing coke from a by-product coke oven cHamber comprising, an elevated support platform extending longitudinally along the coke side of a coke oven battery and positioned at an elevated location above ground level, a quench car movably positioned below said support platform and operable to receive coke discharged from said coke oven chambers, said quench car being movable longitudinally along the side of said coke oven battery, a coke guide movably supported on said support platform and operable to guide the coke from the coke oven chamber into said quench car, an enclosure member movably positioned on the same level as said quench car and operable to move longitudinally along the side of said coke oven battery independently of said quench car, said enclosure member being operable to be positioned in overlying relation with and enclosing said quench car, a first hood member enclosing said coke guide, said first hood member being supported by and movable with said coke guide and having a front open portion, a second hood member extending upwardly from said enclosure member, said second hood member having a rear open portion on substantially the same horizontal plane as said first hood member front open portion and a configuration substantially the same as said first hood member front open portion, said enclosure member operable when aligned with said coke guide to position said second hood member in over-lying relation with said first hood member with said hood member open portions in overlying relation to provide an enclosed passageway for the coke from said coke oven chamber to said quench car positioned within said enclosure, a first conduit extending from said first hood member having an open end portion, a second conduit connected at one end to suction means and air cleaner means mounted on said enclosure member, said second conduit having an open end portion arranged to be aligned with said open end portion of said first conduit to thereby connect said first conduit through said second conduit to said suction means and air cleaner means and thereby collect the dust generated in said coke guide in said first hood member and convey said dust from said first hood member to said air cleaner means, and a third conduit connecting said second hood member to said suction means and air cleaner means to thereby collect the dust generated in said enclosure and convey said dust from said second hood member to said air cleaner means.
