Definitions
- the invention relates to a system for the continuous treatment of Steel strips, in particular for pickling, with a treatment container, made of plastic, preferably made of polypropylene (PP) and with Squeezing rollers at the ends of the treatment tank.
- a treatment container made of plastic, preferably made of polypropylene (PP) and with Squeezing rollers at the ends of the treatment tank.
- PP polypropylene
- the aim of the invention is a plant for the treatment of steel strips create in which the liquid level without problems, especially at the seal, can be adjusted.
- the invention is therefore characterized in that the squeeze rolls in a separate from the treatment tank and at a distance arranged container are provided that the treatment tank and the container of squeeze rolls with one with a Band completely surrounding and the distance from Treatment tank and other container bridging connection shaft are connected.
- This allows the main stream of the Acid cycle in the treatment tank and a seal is only necessary for small amounts of liquid and it can defines a strain compensation can be achieved.
- the Expand treatment container freely, as no firm connections to consist of other components. Also, no complicated seals required.
- connection shaft is designed as a telescopic shaft is.
- a favorable development of the invention is characterized in that in that at least one end of the treatment container has a drain is provided. This will allow the bulk of the Treatment medium, for example, the pickling acid, in the treatment tank circulates and only a small amount to the squeeze rollers arrives.
- the Treatment medium for example, the pickling acid
- a favorable development of the invention is characterized in that that the treatment container is arranged in a cup of plastic and preferably in the middle with this firmly connected. This can the treatment container to expand freely on both sides, without problems of a possible bulging of the soil.
- connection shaft reaches as far as the squeeze rolls, the connection shaft being sealed at the squeeze rolls can.
- a higher liquid level in the Treatment tanks are used, thereby increasing the treatment length of the band to the distance between the squeegee sets elevated. This can also higher in otherwise constant execution Tape speeds and thus achieved a higher production become.
- a favorable development of the invention is characterized in that that at least one end of the treatment tank an overflow is provided. This allows the maximum bath level in the treatment tank be fixed favorably.
- Fig. 1 shows a variant of the invention
- Fig. 2 a represents another variant of the invention.
- Fig. 1 shows a treatment container 1, the bottom 2 by means Supports 3 is supported on the continuous cup 4 made of plastic.
- the steel strip 5 runs in the direction A within the treatment liquid 6 with a liquid level 7.
- a discharge chute 8 is provided into which the liquid runs off and is discharged via a laterally mounted outlet pipe 9.
- Protection strip 10 is provided.
- the protective strip 10 is designed that the band approximately above the wall 11 of the outlet shaft. 8 emerges from the liquid.
- the opposite wall 12 may be by stretching in the direction of arrow D in the cup 4 move.
- a container 13 is provided, in the squeezing rollers 14, 14 'are located. This container can also be closed at the top.
- a similar container 13 together Squeeze rolls 14, 14 'are at the other end of the treatment tank 1 provided.
- the connection of container 1 and container 13 is made by a connection or intermediate shaft 15.
- connection shaft 15 Through this slot 15, the band 5 is guided. At the present Variant reach only small amounts of liquid, if any, in the connection shaft 15. The dripping liquid from the tape is thereby caught by the connection shaft 15.
- connection shaft 15 is fixed at its end 16 to the treatment tank 1 connected.
- the connection can be a plug-in or too Be flange connection. A free movement of the connection shaft 15 in the direction of the squeezing rollers 14, 14 'is possible, so that a Length compensation can be done in a simple manner.
- Fig. 2 shows a variant of the invention, which also referred to as a dust trough can be. It is for high tape speeds, preferably from 150 m / min, suitable.
- the same components have the same reference numerals as in Fig. 1.
- a telescopic shaft 17 for connecting the treatment tank 1 with the container 13 is provided, wherein this at its end 18 at the Wall 12 of the container 1 is flanged.
- the telescopic shaft 17 is at its other end in a sealing piece 19 attached slots 20 led.
- the slot 20 acts with the end of the telescopic shaft 17 as a labyrinth seal.
- a rectangular bellows can be used, which the Elongation absorbs.
- the flow rate can be reduced, creating a Increase of the liquid level in the container 1 from 7 to 7 'takes place.
- Around set the maximum fluid level can laterally Safety overflow 21 may be provided.
- the treatment length of the band on both sides of the Walls 11 to the squeezing rollers 14, 14 ', which also at higher belt speeds achieved sufficient treatment times become.
- a part of the treatment liquid, e.g. Pickling acid will guided here by the telescopic shaft 17 in the container 13, from where the Liquid is returned to the circulation.
- the high Liquid levels 7 ' is only a seal of the container 13 against small amounts of liquid are required, as the liquid level in the Container 13 substantially below the range of strain absorption lies.
