Definitions
- the invention relates to a system for the surface treatment of continuously moving belts, in particular pickling plants, in which the belt runs in the longitudinal direction through a horizontally arranged closed treatment channel, which is arranged inside a container which encloses the treatment channel and is closed by a lid, into which the treatment channel or treatment medium supplied on the outlet side can be derived.
- Treatment plants designed in this way which are known, for example, under the name flat pickling systems, are widely used today and have largely replaced the previously known deep pickling systems.
- the treatment technology of continuously running belts could be significantly improved compared to earlier, because better concentration gradations were achieved, faster belt heating was achieved and the media exchange in the border phase between belt and treatment liquid could be activated.
- the object of the present invention is to optimize the known strip treatment plants, in particular pickling plants of the type described at the outset, in order to shorten the pickling or treatment time even further and to improve the pickling and cleaning quality of the material to be treated.
- a system is proposed according to the invention, which is characterized in that the treatment channel is delimited by the bottom of the container, the treatment channel side walls arranged on this and an intermediate cover on four sides, in that drainage channels are formed between the treatment channel side walls and the container inner walls the treatment medium injected at the treatment channel ends on the inlet and outlet sides can be supplied via central openings provided in the treatment channel side walls and that the drainage channels are connected to collecting spaces via which the treatment medium can be supplied to a separately arranged storage container.
- the advantage of the system design according to the invention is that it is possible to work with a very low liquid level in the treatment channel. This ensures a better exchange of the liquid in the band / medium boundary phase even without the turbulent behavior of the treatment medium.
- the injection of the treatment medium band on the outlet side and in connection with the geometry of the treatment channel and with the support of the side injection also lead to turbulent obsolescence of the treatment medium.
- the turbulence phase of the treatment medium band brings a better heat transfer between acid and band, and thus also a better pickling effect.
- the pickling time can thus be shortened and the output of the system can thus be improved.
- the proposed installation is also advantageous in ecological and economic terms; Because of the advantages of the turbulent flow, lower pickling bath temperatures can be used, so that energy can be saved. With the lower temperatures and the reduced energy supply, the evaporation and exhaust gas development can also be reduced, so that the emission in the air is lower. The pollution of the wastewater is also reduced because the pollution of the plant's wastewater is reduced due to the better purity and lower surface roughness of the belt.
- the arrangement of the system and the use of the intermediate cover arranged on the container lid enables the system to be opened quickly with easy access to the belt in the event of faults.
- two nozzle bars are provided on the inlet side and on the outlet side, through which the treatment medium is injected at a flat angle to the belt, the injected treatment medium serving as a dynamic seal of the treatment channel.
- the band is guided over sliding and liquid guide stones arranged transversely to the direction of the band running on the bottom of the treatment channel.
- guide stones or sheets which conduct the treatment liquid flow be arranged approximately transversely to the band within the treatment channel on the side walls or in the area of the treatment channel side walls.
- Preferred catfish are provided laterally outside the treatment channel, drainage channels for the treatment medium, via which the treatment medium can be returned to the storage container. Due to the constant circulation between the storage container and the treatment channel, the amount of liquid required can be kept low, which also has the advantage that the treatment liquid can be drained from the pickling area in the shortest possible time through the drainage channels into the storage container in the event of faults, such as band breaks or the like, so that the pickling area is quickly accessible to eliminate the fault thanks to the quick-opening lids.
- Fig. 1 denotes the band to be treated, which passes through the system in the direction of the arrow.
- This consists of a container 2, which is closed by a lid 3.
- the cover 3 is laterally sealed with a liquid seal.
- the treatment channel according to the invention is designated 4. This is limited by the bottom of the container, the treatment channel walls 5 shown in FIG. 2 and the intermediate cover 6 on four sides, the intermediate cover 6 being adjustable in height, as indicated at 7, from the container cover 3. There may be little play between the treatment channel walls 5 and the intermediate cover 6.
- the treatment channel according to the invention has sliding or liquid guide stones 8 arranged transversely to the strip running direction in the bottom area, which on the one hand support the strip 1 downwards and on the other hand serve to form turbulence of the treatment liquid.
- the treatment liquid is supplied via nozzle bars 9 and 10, one nozzle bar 9 at the inlet and two nozzle bars 10 at the outlet, the latter above and below the belt, respectively.
- the nozzle bars are fed with the treatment liquid from a storage container 11 via a pump system, which can optionally also be introduced laterally, as indicated at 12, directly into the channel.
- the jet of the treatment medium of the nozzle bars 9 and 10 is directed at a flat angle to the belt, namely from the nozzle bar 9 in the belt running direction and from the nozzle bar 10 in the counter-belt running direction.
- This creates a strong turbulence within the treatment channel 4, which is increased in the lower region of the belt by the liquid guide stones 8.
- Due to the high liquid pressure of the treatment medium a dynamic seal is formed in the inlet and outlet area of the treatment channel 4 by the liquid itself, so that only a little treatment liquid runs back from this area into the collecting spaces 14.
- the collecting spaces 14 are connected to drainage channels 15, which are provided laterally outside the treatment channel in the container and to which the treatment medium is supplied via the drainage 13 in the center of the treatment channel. From there, the treatment medium returns to the reservoir 11 via a return.
- guide devices 16 can be provided on the side of the treatment channel side walls 5, through which the treatment medium flowing in via the nozzle bar 9 is guided approximately transversely to the direction of belt travel. This creates the desired turbulence below the belt between the sliding and liquid guide stones.
