Definitions
- the invention relates to a method for sealing a filling hole closed with a lid on a coke oven, the annular gap between the lid and a Hole frame is sealed with a sealing compound that hardens after the casting process, and taking the sealing compound from a storage container carried on a coal filling truck in one for the annular gap to be sealed beforehand specified amount taken and an annular Distributor is supplied, which is positioned above the annular gap has been.
- SU 1 701 721 A (DATABASE WPI Section Ch, Week 199244 Derwent Publications Ltd., London, GB; Class H09, AN 1992-364455 XP002159036) known.
- the invention has for its object the above To further develop processes so that cleaning and maintenance work largely eliminated.
- the invention teaches that the sealing compound is fed to the manifold under pressure and that after delivery of the specified sealing compound quantities line system connected to the storage container on the outlet side rinsed with water to the distributor, which from a flushing water tank carried on the coal filling truck taken from the distribution system in front of the distributor withdrawn and returned to the rinse water tank.
- the sealing compound is preferably tangential to the distributor fed and emerges from an annular gap a plurality of holes on the bottom of the manifold with a uniform mass distribution in the circumferential direction out.
- a water rinse is carried out after each casting process made to prevent deposits. Further is essential that a matched to the annular gap and previously determined amount removed from the storage container and is fed to the manifold under pressure.
- positive displacement pumps for the funding, their flow rate largely independent of the head is.
- the dosing quantity is over the operating time of the Displacement pump controllable.
- diaphragm and bellows pumps are suitable as well as peristaltic pumps.
- a trained as a pressure vessel Dosing container used. The sealing compound flows out of the Storage container into the dosing container.
- the dosing tank After recording the for the sealing of the annular gap predetermined amount that is determined either by the size of the dosing container or is determined by a level measuring device, the dosing tank is pressurized with compressed air and the sealing compound to form a compressed air cushion fed to the distributor. After emptying the Dosing container this and the outlet side to Distributor leading line rinsed with water.
- a flushing of the annular distributor is then expediently made when the coal filling truck in a coal tower is filled with coal becomes.
- the rinse water emerging from the distributor can be fed to a stationary drainage channel in the coal tower become.
- the invention also relates to a casting device claims 5 and 6 for performing the invention Process.
- the inventive method and the inventive Casting device are characterized by the following advantages.
- the method and the device enable an accurate Dosage of the amount of sealing material, individually can be determined for each fill hole cover.
- the casting process is reliable due to the pressurization and can be carried out quickly with even distribution at the annular gap. Due to the water rinsing that follows a casting process, automatically within the scope of a process control feasible, manual cleaning and Maintenance work.
- the casting device shown in Fig. 1 is on a coal filling truck that is on top of a coke oven battery is movable, installed. It is used around the annular gap between a cover 1, which according to Completion of the coal filling process in the filling hole Coke chamber has been inserted, and the fill hole frame 2 potted with a sealing compound.
- a sealing compound aqueous suspensions with pasty consistency are used, which after the casting process under the effect of the Greochrahmen prevailing temperatures of usually about 200 up to 300 ° C by air drying harden within a few minutes.
- the basic structure of the casting device includes Storage container 3 installed on the coal filling truck Sealing compound, an annular distributor 4, the above of the annular gap to be cast is positionable, and a line system 5 between the reservoir 3 and the Distributor 4.
- the line system 5 has a metering container 6 for receiving one for the annular gap to be sealed predetermined amount of sealing compound. He is designed as a pressure vessel.
- a compressed air line 7 and a rinsing water line 8 connected at the top of the dosing container 6 or in the dosing tank inlet.
- the dosing tank inlet 9, the metering container outlet 10, the compressed air line 7 and the rinsing water line 8 are remotely operable
- Shut-off valves 11a to 11d equipped according to a sequence program described below are controllable.
- the annular distributor 4 has a tangential inlet 12 and is at the bottom with an annular gap or a plurality of outlet bores Mistake.
- the sealing compound supplied under pressure occurs at the bottom of the distributor 4 with a uniform Mass distribution in the circumferential direction.
- the line system 5 including the dosing tank 6 to the distributor 4 rinsed with water.
- the water becomes a rinse water tank 13 removed and by means of a flushing pump 14 when open Shut-off valve 11d let into the dosing container 6.
- a three-way valve 15 arranged in the feed line to the distributor 4 .
- the rinsing water is here from the pipe system 5 withdrawn and through a return line 16 in the rinse water tank 13 returned.
- the rinse water tank 13 has a partition 17 on which the tank in an inlet area 18 and a drain area 19 divided.
- the Inlet area 18 is a sedimentation basin for separation of solids. Purified rinse water flows as an overflow into drain area 19.
- the rinse water tank 13 is regularly filled and cleaned.
- the flushing is expedient of the annular distributor 4 then made when the Coal filling truck in the coal tower being filled with coal.
- the Rinsing water emerging from the distributor 4 can stationary gutter in the coal tower are fed.
