Charging telescope for charging coke ovens
The invention relates to a charging telescope for charging coke ovens, having a vertically oriented inlet funnel and a telescope lower part which is suspended with hanging elements on a vertically adjustable lifting device. A tubular intermediate part is arranged between the inlet funnel and the telescope lower part, which intermediate part is suspended in a movable manner on hanging elements and surrounds the outlet cross section of the inlet funnel with enough free space to allow lateral compensating movements. The intermediate part has an annular flange which is sealed on an annular face of the inlet funnel. The telescope lower part also encloses the jacket of the tubular intermediate part.
1. A charging telescope for charging a coke oven, the charging telescope having an inlet funnel vertically oriented and a telescope lower part, the telescope lower part being suspended with first hanging elements on an adjustable lifting device,
wherein a tubular intermediate part is arranged between the inlet funnel and the telescope lower part, which tubular intermediate part is suspended in a movable manner on second hanging elements and surrounds the outlet cross section of the inlet funnel with enough free space to allow lateral compensating movements,
wherein the tubular intermediate part has an annular flange sealed on an annular face of the inlet funnel, wherein the annular flange and the associated annular face of the inlet funnel extend in an essentially horizontal direction, and
wherein the telescope lower part encloses a jacket of the tubular intermediate part,
wherein a seal is arranged between the annular flange and the annular face of the inlet funnel,
wherein the seal is configured as a hose or a membrane and wherein the interior of the hose or a space enclosed by the membrane is connected to a pressure source,
wherein a pressure can be applied from the pressure source to the seal and
wherein the seal is relieved of pressure during a downward or upward movement of the telescope lower part.
2. The charging telescope according to claim 1 , wherein the second hanging elements are connected to the upper end of the intermediate part.
3. The charging telescope according to claim 1 , wherein the jacket of the tubular intermediate part is tubular, and
wherein the telescope lower part is sealed with a seal against the jacket of the intermediate part.
4. The charging telescope according to claim 1 , wherein the seal is arranged in chambers.
5. The charging telescope according to claim 1 , wherein the jacket of the intermediate part has a cylindrical configuration and is provided with heat insulation at least over a length corresponding to the vertical positioning distance of the telescope lower part.
6. The charging telescope according to claim 5 , wherein the jacket of the intermediate part is configured as a heat-insulated, double-walled component comprising a cylindrical outer jacket and an inner jacket, the inner jacket widening conically towards the upper end.
7. The charging telescope according to claim 1 , wherein the telescope lower part has a cylindrical section and an outlet cone which connects at the bottom,
wherein a sealing element for sealing on the charging hole frame of a coke oven is arranged at the free end of the outlet cone, and
wherein a sealing arrangement for bearing against the jacket of the intermediate part is provided at the upper end of the cylindrical section.
