Embodiment Construction

[0014] The charging telescopic cylinder shown in each figure is fixed to the unloading device 1 on the lower side of a coal charging truck, not shown, and is used to transfer the used coal from the unloading device 1 to the coke oven without any emissions. In the furnace cavity. In terms of its basic structure, the charging telescopic cylinder includes a feeding funnel 2 connected to the unloading device 1, a lower part 3 of the telescopic cylinder, and a tubular insert set between the feeding funnel 2 and the lower part 3 of the telescopic cylinder. 4. The lower part 3 of the telescopic cylinder is suspended on a vertically adjustable lifting device 6 using multiple swing elements 5, preferably multiple swing rods, and can be lowered to the charge in the furnace cover of the coke oven by the adjusting movement of the lifting device 6 Hole frame 7 on. The charging hole frame 7 forms an opening in the furnace cover.

[0015] The tubular insert 4 of the charging telescope is lik...

Abstract

The invention relates to a telescopic chute for charging coke ovens, comprising a vertical feed hopper and a telescopic bottom part that is suspended on a vertically adjustable lifting mechanism by means of a plurality of first swinging elements. A tubular intermediate piece is disposed between the feed hopper and the telescopic bottom part. Said intermediate piece is movably suspended on second swinging elements and surrounds the cross-section of the outlet of the feed hopper in such a way as to leave some clearance that allows for lateral compensating movements. The intermediate piece is equipped with an annular flange which is sealed on an annular surface of the feed hopper. The flange of the intermediate piece and the annular face of the feed funnel extend in an essentially horizontal direction and the telescopic bottom part surrounds a casing of the tubular intermediate piece. A first sealing element is arranged between the flange of the intermediate piece and the annular face of the feed funnel. The telescopic bottom part seals relative to the casing of the tubular intermediate piece by using a second sealing element. The first and the second sealing elements form a flexible pipe or film. The interior of the flexible pipe or the space is connected to a pressure source.

Description

Technical field [0001] The invention relates to a charging telescopic cylinder for charging a coke oven, which comprises a vertically oriented feeding funnel and a telescopic cylinder lower part. The telescopic cylinder lower part is suspended on a vertically adjustable lifting device using a plurality of swing elements on. A charging telescopic cylinder with the characteristics described is known, for example, from DE 199 64 274 B4. Background technique [0002] In the operation of modern coking equipment, the used coal is loaded into the cavity of the coke oven by means of a charging telescopic cylinder on a coal charging cart. The charging telescopic cylinder is composed of multiple pieces and has a sealing device in the boundary area and in the immersion area. The sealing device should prevent the discharge of emissions during the charging process. [0003] In addition, a charging telescopic cylinder is known which has a compensator made of steel or fabric (EP 1 293 552 A). ...
