Abstract

Abstract A tubular coke guide, supported by a carriage in front of a row of coke ovens, receives coke from each oven in succession and discharges it into a quencher car. This car is covered by a stationary housing extending throughout the length of the row of ovens. The housing has a roof and an outer wall extending therefrom down close to the outer side of the quencher car. The bottom and inner side of the housing are open and the inside of the housing is divided into cells by means of transverse upright partitions. The upper part of each cell is provided with a valved outlet connected to a suction line. Upright closure walls supported by the carriage extend from the outer end of the coke guide in opposite directions along the housing far enough to close the side of the cell beside them. The tops of these walls substantially engage the housing roof, and their bottoms are close to the inner side of the car. The cell into which the coke is being discharged therefore will have four side walls and a roof so that the smoke and dust produced in the cell will be drawn out through its outlet by means of the suction line.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 255 words
Apparatus for preventing air pollution during discharge of coke from coke ovens disposed side by side in a row with doors in their front ends, comprising a carriage movable along the front of said row of ovens, a tubular coke guide supported on the carriage for selective positioning thereby in front of the different ovens to receive coke therefrom, a track in front of the carriage parallel to the row of ovens, a quencher car on the track for receiving coke discharged from said guide, a stationary housing permanently mounted to cover said track throughout the length of the row of ovens and having a roof and an outer wall extending therefrom down close to the outer side of said car, the bottom and inner side of the housing being open, transverse upright partitions in the housing dividing it into a plurality of side by side cells, the upper part of each cell being provided with an outlet, a valve for each outlet, a suction line extending along the housing and connected with said cell outlets, and upright closure walls carried by said carriage and extending from the outer end of said tubular guide in opposite directions along said housing far enough to close the side of the cell beside them, the tops of the closure walls substantially engaging the housing roof, and the bottoms of the closure walls being close to the inner side of said car, whereby the cell into which coke is being discharged will have four side walls and a roof.
Claim 2
Dependent Claim 255 words
Apparatus for preventing air pollution during discharge of coke from coke ovens disposed side by side in a row with doors in their front ends, comprising a carriage movable along the front of said row of ovens, a tubular coke guide supported on the carriage for selective positioning thereby in front of the different ovens to receive coke therefrom, a track in front of the carriage parallel to the row of ovens, a quencher car on the track for receiving coke discharged from said guide, a stationary housing permanently mounted to cover said track throughout the length of the row of ovens and having a roof and an outer wall extending therefrom down close to the outer side of said car, the bottom and inner side of the housing being open, transverse upright partitions in the housing dividing it into a plurality of side by side cells, the upper part of each cell being provided with an outlet, a valve for each outlet, a suction line extending along the housing and connected with said cell outlets, and upright closure walls carried by said carriage and extending from the outer end of said tubular guide in opposite directions along said housing far enough to close the side of the cell beside them, the tops of the closure walls substantially engaging the housing roof, and the bottoms of the closure walls being close to the inner side of said car, whereby the cell into which coke is being discharged will have four side walls and a roof.
Claim 3
Dependent Claim 57 words
Apparatus as claimed in claim 1, in which said tubular coke guide is rectangular in cross section and includes a stationary section rigidly mounted on said carriage and a movable section telescoped in the stationary section and movable toward and away from the ovens, said upright closure walls extending away from opposite sides of said stationary section.
Claim 4
Dependent Claim 45 words
Apparatus as claimed in claim 1, in which said outer wall of the housing is provided with said cell outlets and with short pipes connecting them with said suction line outside of the housing, each of said valves being located in one of said pipes.
Claim 5
Dependent Claim 20 words
Apparatus as claimed in claim 3, in which said outer housing wall is inclined downwardly and outwardly from said roof.
Claim 6
Dependent Claim 60 words
Apparatus as claimed in claim 1, in which said outer wall of the housing is substantially vertical, the housing has an interior inclined wall extending diagonally across its outer upper corner from its roof to its outer wall, and said inclined wall extends the length of the housing to form said suction line and is provided with said cell outlets.
Claim 7
Dependent Claim 39 words
Apparatus as claimed in claim 1, in which the upright closure wall that extends from the tubular coke guide forward in the direction of movement of said car during coke discharge is about twice as long as a cell.
Claim 8
Dependent Claim 41 words
Apparatus as claimed in claim 1, including a second carriage close to one end of the first-mentioned carriage, and oven door operating means on the second carriage, the closure wall beside said second carriage being substantially as long as that carriage.
