Definitions
- the present invention relates to a plant for surface treatment of workpieces, which comprises at least one heat sink treatment area, to which heat is to be supplied during operation of the plant, and at least one heat source treatment area, from which heat is dissipated during operation of the plant.
- Such a system for the surface treatment of workpieces can be designed in particular as a system for painting vehicle bodies or parts of vehicle bodies.
- the priming of vehicle bodies comprises in particular the process stages of a pretreatment and an electrodeposition coating (for example a cathodic dip painting).
- process steps of degreasing, phosphating and / or passivation are preferably carried out in immersion baths.
- the electrocoating process step can also be carried out in a dipping bath.
- heat is generated in the dipping bath, since the Tauchlackierbad represents an ohmic resistance through which a current flows in the course of an electrolytic coating.
- process temperatures above room temperature are preferred so that these pre-treatment baths are heated.
- the process temperature in the electrodeposition bath is preferably kept close to room temperature, so that the dip-coating bath is cooled again due to the evolution of heat during an electrolytic paint deposition.
- hot water from a central heating system with a flow temperature of, for example, about 80 ° C. to 100 ° C. is used as the heating medium.
- the present invention has for its object to provide a system for the surface treatment of workpieces of the type mentioned, which requires less energy for the heating of the at least one heat sink treatment area and the cooling of the at least one heat source treatment area.
- system comprises at least one heat pump device, which is coupled to receive heat with at least one heat source treatment area and heat to at least one heat sink treatment area ,
- the heat-related coupling of at least one heat source treatment area, for example an electrodeposition bath, and at least one heat sink treatment area, for example a treatment bath in the pretreatment area results in a significant energy saving achieved.
- the units required for the thermal coupling of the heat source treatment area and the heat sink treatment area can be in immediate spatial proximity to the heat source treatment area and to the heat sink treatment area be arranged so that it is no longer necessary to connect the heat source treatment area via long pipes with a central refrigeration system or to connect the heat sink treatment area via long pipes with a central heating system. This contributes to a reduction of the apparatus cost and thus the required investment costs.
- the temperature levels for the cooling and for the heating process can be optimally determined.
- the temperature level for cooling may be increased from a common cooling medium temperature of, for example, about 10 ° C to a cooling medium temperature of, for example, about 20 ° C, and / or the temperature level for heating lowered from a common heating medium temperature in the range of, for example, about 80 ° C to 100 ° C to a heating medium temperature of, for example, about 70 ° C.
- the system for the surface treatment of workpieces as a system for painting workpieces, in particular of Fa h rzeugka rosse rien or parts of vehicle bodies, is formed.
- At least one heat sink treatment area may comprise a pretreatment bath of the installation, in particular a degreasing bath and / or a phosphating bath.
- At least one heat source treatment area may comprise a dip paint bath and / or a lock area of the installation.
- the lock area of the installation may in particular be connected upstream of a pretreatment area of the installation.
- At least one heat pump device of the system can be connected to receive heat with a cooling circuit in which a Heat transfer medium for receiving heat from a heat source treatment area is circulated, and / or connected to a heating circuit, in which circulates a heat transfer medium for delivering heat to a heat sink treatment area.
- At least one heat pump device of the system for receiving heat and / or for the release of heat is coupled to an air circuit of the system.
- Such an air circuit can in particular serve to generate an air curtain in a lock area of the installation.
- the system comprises a condenser for cooling and / or dehumidifying air in the air circuit.
- a condenser can in particular serve for evaporating a refrigerant in a refrigerant circuit of a heat pump device coupled to the air circuit.
- the system comprises a condensate discharge line, by means of which condensate condensed in the condenser from the air can be supplied to a treatment bath of the system, for example a degreasing bath. In this way not only energy from the air circulation but also liquid evaporated from the treatment bath can be returned to the treatment bath.
- the air circuit comprises a device for producing an air curtain, through which pass the workpieces to be treated during operation of the system.
- such an air curtain can serve to separate the atmosphere of the area behind the air curtain from the atmosphere of the air curtain area of the installation. In particular, so the escape of moist vapors from one of these areas in the environment and a carryover of impurities through the air curtain are avoided.
- the device for producing the air curtain comprises a device for dividing the air flow guided in the air circuit into a first air chamber and a second air chamber, wherein the first air chamber has a nozzle for generating a bundled air jet and the second air chamber an air curtain adjacent Outlet opening is connected downstream.
- the bundled air jet generated by means of the nozzle sucks circulating air from the second air chamber.
- At least one heat source treatment area of the installation may comprise a rinsing bath, preferably a rinsing bath connected downstream of a treatment bath of the pretreatment area, in particular a phosphating bath. Since the heat introduced into the rinse bath can not normally be used further in subsequent treatment areas, the use of a heat pump is expedient for extracting heat from the rinsing bath (or several rinsing baths) and optionally at a higher temperature level into a heat sink treatment area of the surface treatment facility feed.
- At least one heat source treatment region of the plant may comprise an activation bath, preferably an activation bath preceding a phosphating bath.
- an activation bath for example, crystal nuclei are rinsed onto the workpiece surface in order to improve the crystal formation in the subsequent phosphating.
- the activation bath preferably contains a colloidal dispersion with titanium phosphate nuclei, which decomposes in a time dependent on the temperature of the activation bath and becomes inactive.
- the temperature in the activation bath is set between about 35 ° C and about 45 ° C. If workpieces to be treated in a treatment station upstream of the activation bath, for example in a degreasing, are heated, heat is introduced into the activation bath, which may at least temporarily require cooling of the activation bath.
- the use of a heat pump would be useful to extract heat from the activation bath and feed it at a higher temperature level in a heat sink treatment area of the surface treatment plant.
- heating may also be provided.
- a heating is provided in particular if, during a production interruption, the activating bath has cooled below the treatment temperature. Cooling is provided, for example, when the bath temperature of the activating bath rises above a predetermined desired value via a heat input of the workpieces.
- At least one heat-source treatment region of the system may comprise a nano-coating bath, preferably a nano-coating bath connected downstream of a degreasing bath and / or a rinsing bath.
- the nano-coating bath or thin-film bath may serve to replace phosphating performed in a conventional workpiece coating process.
- a coating on the chemical basis of silanes or zirconia is carried out, resulting in layer thicknesses in the range of about 20 nm to about 200 nm.
- the treatment times in the nano-coating bath are adjusted depending on the temperature, for example, between about 30 seconds and about 120 seconds. While phosphating requires tempering of the phosphating bath to a temperature of from about 40 ° C to about 60 ° C, the nano-coating process also proceeds at lower temperatures between about 10 ° C and 50 ° C. higher Temperatures lead to a higher layer thickness and lower temperatures to a smaller layer thickness.
- a particularly preferred temperature range for the nano-coating bath is in the range of about 20 ° C to about 30 ° C.
- Exact temperature control of the nano-coating bath not only results in complete layer formation, but also in uniform coating thickness distribution in the nano-coating. If the nano coating is followed by an electrophoretic dip coating, in particular a cataphoretic dip coating, as an electrical deposition method, the dip coating method reacts very sensitively to different electrical resistances of the background material. If the nano-coating has thickness differences, this will also be noticeable in different layer thicknesses of the layer produced by a subsequent dip-coating.
- heating of the bath is also possible as an alternative or in addition to cooling. Heating is required in particular when, during a production stoppage, the nano-coating bath has cooled below a permissible treatment temperature. Cooling is required in particular when the bath temperature of the nano-coating bath rises above the setpoint value via a heat input. It is particularly advantageous if the heat removed from the nano-coating bath or the activating bath is fed by means of a heat pump at a higher temperature level into a degreasing bath of the surface-treatment plant.
- the cooling power required for cooling the nano-coating bath or the activating bath can be reduced and the heating power required for heating the degreasing bath can also be reduced.
- the efficiency of the heat pump device can be increased if at least one heat pump device comprises at least two heat exchangers for supplying heat to the respective heat pump device.
- At least two of the heat exchangers are flowed through by heat carriers of different temperature on the hot side, wherein in particular the first heat carrier, which flows through a cold side of the first flowed through first heat exchanger warm side, a lower temperature than the second heat carrier, which later cold side flows through the refrigerant second heat exchanger flows through the warm side.
- the at least two heat exchangers are coupled to two different heat source treatment areas in order to be able to supply heat to the heat pump device from at least two different heat source treatment areas, in particular at different temperature levels. In this way, the lower temperature level T 0 can be increased and thus the efficiency can be increased.
- the lower temperature level is, for example, about 30 ° C and the upper temperature level, for example, about 60 ° C, resulting in a COP of about 5 , 5 results.
- the refrigerant in the refrigerant circuit of the heat pump device first through a first heat exchanger in which it absorbs heat from the activation bath or the nano-coating bath, and then passed through a second heat exchanger in which it heat from a rinsing bath, in particular from a degreasing bath downstream rinsing bath,
- the lower temperature level is raised to approximately 40 ° C or approximately 45 ° C by this cascade guide, thereby increasing the efficiency of the heat pump device COP to approximately 8.3 and approximately 11, respectively, which is a significant improvement.
- the first and the second heat exchanger in this case together form an evaporator of the heat pump device, wherein the evaporation of the refrigerant in the refrigerant circuit of the heat pump device can be partially in the first evaporator and partially in the second heat exchanger or completely in the first heat exchanger or completely in the second heat exchanger.
