Combined control device for the operation of coke oven batteries to effect switching of the regenerative heating system from one group of flues to another and for converting from one heating gas to another

摘要

A combined control device for the operation of coke oven batteries which includes both a part for converting from heating with a strong gas to a lean gas, and vice versa, and a part for switching the regenerative heating system from one group of heating flues to another, comprises a support frame on which is mounted a rotary switching control cylinder and a rotary conversion control cylinder in end-to-end relationship and for rotation around the same axis. The rotary conversion control cylinder is displaceable in respect to the rotary switching control cylinder, and the two cylinders may be coupled together for rotation together or the conversion cylinder may be shifted axially so that it will not rotate with the switching control cylinder. The switching control cylinder is driven at one side from a motor driven transmission which also permits the manual operation of the cylinders. A plurality of axially spaced, circumferentially arranged cam tracks are arranged on each of the two cylinders at spaced axial locations along their lengths and in alignment with switching valves that are similarly oriented along the length of the two cylinders.
