Definitions
- the invention relates to a telescopic tube for a discharge device on a loading cart for coke ovens with a filling pipe, a vertical one enclosing the filling pipe adjustable outer tube and a sealing arrangement for Sealing the annular gap between the filling pipe and the Outer tube during the loading of a coke oven Coal.
- the Telescopic tube is formed in several parts and at least has a filling pipe connected to the discharge device and a liftable and lowerable outer tube. Special value is in the execution of the telescopic tube on a tight Execution laid so that during the coal filling in the coke oven chamber no fill emissions through the telescopic tube get into the environment.
- known telescopic tube has the fixed to the discharge device connected filling pipe at its lower end a ring-shaped collar filled with sand.
- the known design allows it not, height differences between the lower edge of the lowered Compensate outer tube and the Greochrahmen.
- the cuff usually made of steel or one Special fabric made, has only a limited stretch, which are directly related to their overall length stands and neither by the constructive execution nor is significantly influenced by the choice of material.
- the Distance between the lower edge of the telescopic tube when raised Condition and the top edge of the Medoch frame often greater than the allowable expansion of the compensator, so that Entire furnace ceiling areas with the Grep frame in complex and raised actions associated with significant costs and in the range of the allowable expansion joints have to be brought.
- the invention has for its object a telescopic tube of the intended purpose described at the beginning, that any distance between in a large work area the lower edge of the telescopic tube and the upper edge of the fill hole frame of a coke oven bridged and the leakage of Filling emissions effectively prevented.
- the task is with a telescopic tube of the entrance described construction according to the invention solved in that the sealing arrangement encloses the filling pipe, elastically deformable seal as well as a seal has acting clamping device and that the clamping device with a drive for operational clamping and release is equipped.
- the elastic seal is by clamping the clamping device against the filling pipe and can be pressed against a flange surface connected to the outer tube. By loosening the clamping device, the seal comes of the filling pipe wall again free, so that the outer pipe without Wear of the seal is vertically adjustable.
- the seal can consist of several sealing rings arranged one above the other consist.
- Pneumatic or hydraulic cylinders are used as the drive, electromechanical actuators as well as manual actuatable mechanical drives can be used.
- the drive has at least one hydraulic cylinder / Piston arrangement on.
- a first embodiment is the seal in one of two Flange rings limited and connected to the outer tube annular housing arranged radially from one in the tensioned strap is inserted into the housing.
- the seal is expediently divided in the longitudinal direction and forms together a clamping ring with the strap.
- clamping device released the inner diameter of the clamping ring is slightly larger than that Outside diameter of the filling pipe, so that when lowering and Lifting the outer tube no direct contact between There is a clamping ring and filling tube and a mechanical output the seal is excluded.
- the drive has a contracting on the ends of the strap Traction device, e.g. a linear drive with a Cylinder / piston arrangement.
- the seal pressurized in the radial direction during the clamping process.
- Another embodiment of the invention provides that the seal in one of a flange ring and one Pipe section limited annular space and arranged by a vertically adjustable connected to the drive Clamping ring is acted on in the axial direction.
- the seal is moved by a vertical movement of the clamping ring pressed together and to the filling pipe as well as on the corresponding contact surfaces of the outer tube pressed. After loosening the clamping device, it deforms the seal back so that the outer tube is adjusted vertically can be without the seal wear is exposed.
- the telescopic tube 1 shown in Fig. 1 is to the Discharge device 2 of a loading trolley, not shown connected on the furnace ceiling 3 a coke oven is movable.
- the telescopic tube 1 has a filling pipe firmly connected to the discharge device 2 4 and a vertically adjustable one enclosing the filling pipe 4 Outer tube 5 on.
- Via a support ring 6 and Articulated rods 7 is the outer tube 5 with a lifting beam 8 connected.
- a sealing arrangement 10 which the annular gap between the filling tube 4 and the outer tube 5 during the loading sealing the coke oven chamber with coal prevents during coal filling filling emissions through the telescopic tube get into the environment.
- FIGS. 2 to 4 show the structure of the sealing arrangement 10. It has an elastic surrounding the filling tube 4 deformable seal 11 and a seal 11 acting clamping device 12.
- the jig 12 is with a drive 13 for operational clamping and Solve equipped.
- tensioning the jig 12 is the elastically deformable seal 11 against that Filling tube 4 and against one connected to the outer tube 5 Flange surface can be pressed.
- the seal 11 comes free from the filling pipe wall, so that the outer tube 5 is raised without wear of the seal 11 or can be lowered.
- the seal 11 can, like indicated in FIGS. 2 and 4, from several one above the other arranged sealing rings exist.
- the seal 11 in one of two flange rings 14 limited and connected to the outer tube 5 annular housing 15 arranged and radially from one tensioned in the housing 15 inserted strap 16.
- the seal 11 is advantageously divided in the longitudinal direction and forms a clamping ring with the strap 16, which by the the ends of the tensioning band contracting drive 13 can be clamped against the wall surface of the filling tube 4 (Fig. 3).
- the drive 13 is in the embodiment with a hydraulic cylinder / piston arrangement as pulling device educated. Pneumatic cylinders, electromechanical, are also suitable Actuators or manually operated Actuators.
- FIG. 4 10 is the seal 11 in one of one Flange ring 14 and a tubular section limited annulus arranged and connected by a drive 13 vertically adjustable clamping ring 18 in the axial direction acted upon.
- the left representation of FIG. 4 that is Lowered outer tube 5 for a filling process and the Clamping device 12 cocked.
- the from several sealing rings existing seal 11 is by an actuating movement of the upper clamping ring 18 pressed and is under pressure both on the filling pipe 4 and on the corresponding Contact surfaces of the outer tube 5.
- the right half of the 4 shows the sealing arrangement 10 with the tensioning device released 12.
- the drive 13 is relieved, and the upper one Clamping ring 18 rests on the seal 11 without pressure.
- the elastic sealing rings have deformed back, whereby between the seal 11 and the outer surface of the filling tube 4 a gap s can be seen.
- the outer tube 5 is vertically adjustable without wearing the seal 11.
