Abstract
An extendible hopper is mounted to the undercarriage of a pusher machine and is operable to be extended to engage the face of the coke oven battery, between the buckstays and just below the door jamb, to catch hot coke that spills out of coke ovens as the door is removed and the pusher ram is retracted. A bin is also mounted to the undercarriage of the pusher machine to receive the hot coke collected by the extendible hopper. Quench sprays are mounted to the bin to quench the hot coke, and suction means are mounted to the bin to draw off pollutants that emanate from the hot coke and the quench thereof.
Claims8
In a coke oven pusher machine, including a pusher ram and a door machine, the improvement comprising:
- (a) hopper means, mounted to the undercarriage of said pusher machine and operable to be extended to a position adjacent to the lower edges of the pusher side doorways of the coke ovens of the coke oven battery with which the coke oven pusher machine is associated, to collect material spilled from said coke ovens;
- (b) powered means, mounted to said pusher machine, for extending said hopper means to said position adjacent and for retracting said hopper means to within said undercarriage of said pusher machine;
- (c) gravity release means, mounted to the bottom of said hopper means, operable to release said material from within said hopper means, when said hopper means has been retracted to within said undercarriage of said pusher machine;
- (d) bin means, mounted to said undercarriage of said pusher machine, positioned beneath the retracted position of said hopper means, operable to collect said material released from said hopper means by said gravity release means;
- (e) gate means, mounted to the bottom of said bin means, operable to dump said material which becomes accumulated within said bin means, said gate means which permits the flow of water therethrough from within said bin means;
- (f) quench water spray means, mounted to said bin means, operable to spray water onto said material within said bin means;
- and
- (g) conduit means, mounted to said bin means, operable to conduct away gases and airborne particulates which emanate from said material within said bin means.
A system for collecting and disposing of coke oven battery pusher side door spillage, wherein said coke oven battery includes a pusher machine, a plurality of horizontal slot-type coke ovens and a pusher side bench, comprising
- (a) hopper means, mounted to the undercarriage of said pusher machine and operable to be extended to a position adjacent to the lower edges of the pusher side doorways of said coke ovens to collect material spilled from said coke ovens;
- (b) powered means, mounted to said pusher machine, for extending said hopper means to said position adjacent and for retracting said hopper means to within said undercarriage of said pusher machine;
- (c) gravity release means, mounted to the bottom of said hopper means, operable to release said material from within said hopper means when said hopper means has been retracted to within said undercarriage of said pusher machine;
- (d) bin means, mounted to said undercarriage of said pusher machine, positioned beneath the retracted position of said hopper means, operable to collect said material released from within said hopper means by said gravity release means;
- (e) gate means, mounted to the bottom of said bin means, operable to dump said material which becomes accumulated within said bin means, said gate means which permits the flow of water therethrough from within said bin means;
- (f) quench water spray means, mounted to said bin means, operable to spray water onto said material within said bin means;
- (g) conduit means, mounted to said bin means, operable to conduct away gases and airborne particulates which emanate from said material within said bin means;
- (h) trough means, located adjacent the base of said coke oven battery and extending the length thereof along the pusher side bench, operable to continuously drain off water which flows from said bin means through said gate means;
- (i) slide means, positioned adjacent said lower edges of said pusher side doorways of said coke ovens, operable to direct material spilled from said coke ovens into said hopper means;
- and
- (j) pivotable hand rail means, extending the length of the outboard edge of said pusher side bench, arranged to pivot out of the way as said hopper means is extended to said position adjacent and to return pivot as said hopper means is retracted to within said undercarriage of said pusher machine.
