Definitions
- the invention relates to a device for operating and a method for converting a system for, in particular continuous, treatment, preferably for cleaning, a metal strip by means of a treatment liquid, in particular a pickling liquid, the metal strip, preferably horizontally, through at least one tank for holding the treatment liquid , in particular a pickling tank, with at least one pumping tank, preferably two pumping tanks, for the preparation and / or storage or provision of the treatment liquid.
- AT 407759 B From AT 407759 B it is known to provide flat tanks with special injection devices for the treatment liquid. AT 407759 B also schematically shows the system concept with the pumping tank without revealing a particularly space-saving arrangement.
- the object is solved according to the inventive apparatus according to the characterizing portion of claim 1 and according to the ⁇ method according to the characterizing portion of claim 20 of invention.
- the measures according to the invention make it possible to create a very space-saving and compact treatment system which enables very efficient treatment, offers clear advantages in operating costs and thus improves the treatment process as a whole.
- one or more pumping tanks are arranged directly under the tank for holding the treatment liquid.
- Pumped-over tanks serve for the preparation but also for the absorption of the treatment liquid when emptying the tanks.
- the tank for holding the treatment liquid is designed as a flat tank with a lid.
- pollution of the environment or the immediate system environment by the treatment medium can be avoided.
- the design as a flat tank enables a very efficient interaction between the belt and the treatment liquid. A particularly good treatment result can thus be ensured on the metal band.
- a further embodiment of the device provides that the pumping tank or tanks and the tank form a unit.
- the system can be kept very compact, which, in addition to the advantages already mentioned, also gives rise to advantages with regard to the space requirement and the assembly process of the system parts.
- the tank is structurally placed on one or more pumping tanks.
- This version allows very simple assembly and disassembly and enables a cost-effective, simple design for the tanks and the pumping tanks.
- seals are provided on the contact surface between the tank and pumping tanks. This ensures that volatile components of the treatment liquid, e.g. Vapors, do not get into the environment.
- the lid to or Umpumptanks In a very compact embodiment of the apparatus of the bottom of the tank is "the lid to or Umpumptanks. This minimizes space requirements and provides for assembly as maintenance a significant advantage as the components can be easily disassembled or serviced. The The difference in level between the surfaces of the treatment liquids in the tank and in the pumping tanks can thus be minimized.
- a very advantageous embodiment of the device is achieved by the design of the tank and pumping tank made of plastic, polypropylene in particular being used. This ensures a long service life and high operational reliability.
- the good processing properties such as weldability, enable the construction of complex components and the assembly of assemblies into one structural unit.
- the tank and pumping tanks are made of rubberized steel or of other materials resistant to the treatment liquid, such as stainless steel. This is a very robust and reliable solution and can be used for assembled components.
- components that are in direct contact with the treatment liquid, such as a tank or pumping tank can advantageously be designed in this way.
- the device according to the invention has drainage chambers which receive the treatment liquid emerging from the tank, caused by the movement of the metal strip or due to turbulence, and guide it into the pumping tank or tanks.
- the tank and the pumping tank (s) are connected via an additional drain, absorbing a change in length, so that the tank can be emptied in a simple manner via this drain.
- the large lengths of the tanks and the increased operating temperatures lead to considerable, thermally induced changes in length which are absorbed by the process according to the invention.
- the drain between the tank and the pumping tank is provided in the middle of the tank, as seen in the direction of belt travel, the bottom of the tank being designed inclined toward the drain, so that when the treatment liquid is drained, the tank is always completely drained.
- the pumping tank has a bottom, which has a gradient over the entire length, the gradient being aligned in the direction of travel of the belt.
- Manhole or cleaning openings with a removable cover are provided for maintenance and repair work, so that downtimes caused by necessary work can be kept very short.
- the drain chambers each have a flap which is arranged between the partition and the outer wall of the drain chamber and can be actuated from the outside.
- This flap enables gas-tight closing of the pumping tanks.
- MAK max. Workplace concentrations
- the level difference between the liquids between the tank and the pumping tank can be kept very small, so that shorter piping and a lower energy input when pumping the treatment medium is possible.
- the pumps are arranged in the immediate vicinity of the tanks or the pumping tanks.
- a method according to the invention for converting a treatment device for cleaning a metal strip by means of a treatment liquid, in particular a pickling liquid, the metal strip preferably being guided horizontally through at least one tank, in particular a deep tank, for holding the treatment liquid, is composed of the following features:
- the existing tanks in particular deep tanks of a deep tank belt cleaning system, are removed.
- One flat tank and one or more pumping tanks are installed instead of the removed tank.
- the deep tanks are replaced by the advantageous flat tanks and the treatment result is improved.
- the common arrangement, the pumping pump or pumps being arranged directly below the flat tank, offers advantages for the conversion process in addition to the operational advantages.
- the described method for the conversion is characterized by a small space requirement and small necessary structural changes or extensions, since no additional space requirement arises from the conversion. Due to the lower structural measures, shorter and less expensive renovation phases realizable. A shorter assembly phase can also be achieved by combining components.
- Fig.1 Arrangement of the facilities of the treatment plant
- Fig.2 Detail from Fig. 1 to the facilities of the treatment plant
- Fig. 3 sectional view of the treatment plant in a preferred embodiment
- Fig. 4 sectional view of the treatment plant in a further preferred embodiment
- a treatment device is shown schematically and in sections in elevation.
- two pumping tanks 3 are arranged on a support structure, only indicated here. These pumping tanks 3 are positioned directly under the tank 1.
- the tank 1 serves to hold the treatment liquid, preferably a pickling liquid.
- a metal strip 2 to be treated is passed through the tank 1, essentially horizontally, the metal strip 2 being cleaned by the interaction with the treatment liquid.
- Protective devices 7 for protecting the tank 1 from damage by the metal strip 2 are arranged in the tank 1.
- Drainage chambers 4 are arranged at the inlet and outlet of the tank 1 and also hold the squeeze rollers 5.
- the pumping tanks 3, arranged directly below the tank 1, are connected to the tank 1 via the outlet chambers 4 and a centrally arranged outlet 6.
- the drain chambers 4 are each connected to a pumping tank 3 via lines 8.
- the drain 6 and the lines 8 are designed in such a way that changes in length due to thermal conditions can be accommodated in the device parts.
- the amounts of liquid are indicated via the liquid level.
- the tank 1 has a bottom 9 that slopes towards the outlet 6, which ensures that when the tank 1 is emptied, no residues of the treatment liquid remain in the tank 1.
- FIG. 2 shows an enlarged detail from FIG. 1.
- flaps 10 which can be actuated from the outside and which are gas-tight and which are arranged between a partition 11 and the outer wall 12 of a drainage chamber 4.
