Definitions
- Drying module continuous drying system and process for drying painted workpieces and/or painted assemblies
- the invention relates to a drying module for a continuous drying system for drying painted workpieces and / or painted assemblies, in particular painted vehicle bodies, having at least one module housing, at least one drying tunnel, which is enclosed radially on the outside by the module housing with respect to its longitudinal extent and in which through the drying tunnel continuous painted painted workpieces or assemblies can be acted upon with drying air, and at least one intermediate space arranged between the module housing and the drying tunnel.
- the invention also relates to a continuous drying system for drying painted workpieces and/or painted assemblies, in particular painted vehicle bodies.
- the invention further relates to a method for drying painted workpieces and/or painted assemblies, in particular painted vehicle bodies, using at least one drying module of a continuous drying system.
- paint coatings on substrates such as vehicle bodies
- hot drying air to coated substrates in a continuous drying system. This drying is used in particular in automobile production, for example for drying vehicle bodies painted using a cathodic dip-coating process.
- a conventional continuous system for drying painted vehicle bodies is known.
- the system has a continuous dryer and separately arranged means for generating hot drying air, which are connected to the continuous dryer via drying air lines in order to be able to supply hot drying air to the continuous dryer and remove it from it.
- a disadvantage of such a conventional drying system is that a relatively large amount of heat is lost to the environment via the drying air lines, which affects the energy efficiency of such a conventional drying system.
- One object of the invention is to enable more energy-efficient drying of painted workpieces and/or painted assemblies, in particular painted vehicle bodies, with less assembly effort.
- a drying module according to the invention for a continuous drying system for drying painted workpieces and / or painted assemblies, in particular painted vehicle bodies has at least one module housing, at least one drying tunnel, which is enclosed radially on the outside by the module housing with respect to its longitudinal extent and in which the painted parts passing through the drying tunnel Workpieces or assemblies can be acted upon with drying air, and at least one intermediate space arranged between the module housing and the drying tunnel, the intermediate space being connected to the drying tunnel via at least one air inlet of the drying tunnel and via at least one air outlet of the drying tunnel to form at least one drying air circuit is and in the gap at least one drying air blower, with which the drying air can be circulated within the drying air circuit, and at least one electric drying air heating device, with which the drying air can be heated within the gap, are each at least partially arranged.
- a drying air circuit is constructed entirely within the drying module or the module housing of the drying module. Therefore, according to the invention, means for generating hot drying air arranged separately from the drying module and drying air lines for connecting the drying module to the means for generating hot drying air arranged separately from the drying module are unnecessary and not present. This eliminates heat loss via such means and drying air lines, which means that the drying module according to the invention can be operated in a significantly more energy-saving or energy-efficient manner than conventional drying modules.
- a continuous drying system having the drying module or drying modules according to the invention can also be designed to be significantly more space-saving and installed with significantly reduced assembly effort.
- this assembly effort is reduced even further, since the electric drying air heating device only has to be connected in a simple manner to an existing electrical network. There is no need to connect the electric drying air heating device to fluid-carrying systems, so that ultimately the installation of such fluid-carrying systems can be omitted, which further reduces the assembly effort.
- the electrical drying air heating device does not have to be separated from fluid-carrying systems in the drying module according to the invention, so that the repair and/or maintenance effort associated with the drying module according to the invention is reduced compared to conventional drying modules.
- assembly and operating costs of a continuous drying system for drying painted workpieces and/or painted assemblies, in particular painted vehicle bodies, painted body components or other painted vehicle components can be significantly reduced.
- the module housing is preferably also designed to be thermally insulating in such a way that heat losses via the module housing are largely reduced.
- the module housing can be partially or completely designed according to DE 10 2014 015 705 A1 or provided with correspondingly designed walls be.
- the content of DE 10 2014 015 705 A1 is hereby incorporated in its entirety by reference into the present application.
- the module housing can in particular be cuboid-shaped and have at least a ceiling, a floor and two side walls.
- the dimensions of the module housing can be selected such that the drying module as a whole can be transported with a transport vehicle, in particular a truck.
- the drying module can be largely or completely prefabricated by the manufacturer, then transported to the respective location and installed there in a simple manner and with little expenditure of time.
- the ceiling, the floor and / or the side walls can be at least partially modular, so that the length of the module housing depends on the number of ceiling modules and floor modules used and/or side wall modules can be determined.
- the drying tunnel can, for example, run centrally through the module housing.
- the drying tunnel can be designed in such a way that the longitudinal directions of painted vehicle bodies passing through the drying tunnel are aligned parallel or transverse to the longitudinal extent of the drying tunnel.
- the drying tunnel can be enclosed radially on the outside by a ceiling, a floor and side walls of the module housing.
- the drying tunnel can be laterally delimited by an intermediate wall on which one or more air inlets can be arranged in order to be able to apply the drying air to the painted workpieces or assemblies passing through the drying tunnel.
- the space of the drying module can be arranged, for example, between such an intermediate wall and a side wall of the module housing.
- the at least one air inlet of the drying tunnel can be formed on the intermediate wall.
- the air inlet can be designed as a simple opening in the intermediate wall or as an air nozzle arranged at an opening in the intermediate wall.
- the intermediate space, the drying tunnel, the at least one air inlet of the drying tunnel and the at least one air outlet of the drying tunnel form sections of the drying air circuit formed within the drying module or module housing, within which the drying air is supplied by means of the drying air circuit.
- fan can be circulated.
- the gap can be connected to the drying tunnel directly or indirectly via the at least one air inlet of the drying tunnel and/or directly or indirectly via the at least one air outlet of the drying tunnel.
- the drying air blower is partially or completely arranged within the gap.
- an impeller or blade wheel of the drying air blower with which the drying air can be circulated within the drying air circuit, can be arranged completely within the gap, while an electric motor of the drying air blower that drives the impeller or blade wheel is partly inside the gap and partly outside the gap, in particular partially can be arranged outside the module housing, or completely inside or outside the space, in particular completely outside the module housing.
- the drying module can also have two or more drying air fans.
- the electric drying air heater is partially or completely arranged within the intermediate space.
- the electric drying air heating device can have at least one heating resistor unit with which the drying air can be heated within the intermediate space.
- the drying module can also have two or more electric drying air heaters.
- the drying module according to the invention is particularly suitable for a continuous drying system for drying painted workpieces and/or painted assemblies, in particular painted vehicle bodies.
- the drying module can be used to carry out thermal treatment of workpieces for a purpose other than drying a paint or coating, for example for curing an adhesive or the like.
- a varnish is to be understood as meaning any curable coating, for example a primer, a top coat, a protective varnish or the like.
- the space is arranged between a side wall of the module housing and an intermediate wall that laterally delimits the drying tunnel, with the at least one air inlet of the drying tunnel being arranged.
- Tunnel is arranged on the partition wall.
- Such an intermediate wall or a corresponding gap can be present on both sides of the drying tunnel, in each of which at least one drying air blower and at least one electric drying air heating device are present.
- the gap can be present above or below the drying tunnel.
- At least one infrared radiation unit is arranged on a side of the intermediate wall facing the drying tunnel.
- the infrared beam unit which can also be controlled electrically, can be arranged, for example, in an area of the side wall in which the at least one drying air blower and the at least one electric drying air heating device are not arranged directly on an opposite side of the intermediate wall.
- the infrared radiation unit can be arranged on the input side in the drying tunnel with respect to a direction of travel of the painted workpieces or assemblies in order to be able to form a preheating zone, after which a heating zone can follow in which the at least one drying air blower and the at least one electric drying air heating device are arranged.
- Two or more infrared radiation units can also be arranged distributedly on the side of the partition wall facing the drying tunnel.
- the drying air blower and/or the electric drying air heating device can be mounted as intended on the drying module or removed from the drying module from outside the module housing. This makes it possible, for example, in the event of a repair, to remove the drying air blower and/or the electric drying air heater from outside the module housing from the drying module and to replace it with a functional drying air blower or a functional electric drying air heater.
- the drying module can be designed in such a way that the drying air blower and the electrical drying air heating device are arranged on the drying module independently of one another or together as an assembly so that they can be mounted or removed from outside the module housing.
- This ability to mount or dismantle the drying air blower and/or the electric drying air heating device from outside the module housing allows, for example, a quick replacement in the event of damage a defective drying air blower and/or a defective electrical drying air heating device, so that an appropriately equipped continuous drying system can quickly be operated in normal drying mode again, i.e. without there being long downtimes in which the drying module would cool down, which is disadvantageous with an increased energy requirement for the subsequent reheating of the drying tunnel or components delimiting it would be associated.
- the drying module has at least one heating zone and at least one holding zone upstream or downstream of the heating zone with respect to the longitudinal extent of the drying tunnel, the drying air blower and the electric drying air heating device being arranged in the heating zone.
- a maximum drying air temperature can be established in the heating zone in order to bring about a specific thermal treatment, in particular drying.
- the painted workpiece heated in the heating zone or the painted assembly heated in the heating zone, in particular the painted vehicle body can be kept at a desired temperature, for which less energy is required.
- a length of the heating zone can essentially be a length of the holding zone.
- the drying module can also have two or more heating zones and/or holding zones. The heating zones and the holding zones can, for example, be arranged alternately.
- the drying module has at least one bottom-side conveyor unit with which the painted workpieces or assemblies can be conveyed through the drying tunnel.
- the conveyor unit can have rails running through the drying tunnel and carriages guided on the rails, which can each be used to carry a painted workpiece or a painted assembly, in particular a painted vehicle body.
- the conveyor unit can be designed as a longitudinal conveyor unit, in which the longitudinal directions of the conveyed painted vehicle bodies are aligned parallel to the longitudinal extent of the drying tunnel, or as a transverse conveyor unit, in which the longitudinal directions of the conveyed painted vehicle bodies are aligned transversely to the longitudinal extent of the drying tunnel.
- the conveyor unit can be of conventional design.
- At least one sliding door is arranged on at least one end wall of the drying module that runs transversely to the longitudinal extent of the drying tunnel, with which a through opening arranged on the end wall can either be closed or at least partially opened.
- the sliding door can release the front passage opening in order to be able to move the painted workpieces or assemblies into or out of the drying module.
- the drying module can be arranged, for example, at the beginning or at the end of a continuous drying system, so that the continuous drying system can be closed at the end outside of the drying operation by means of the sliding door in order to keep the heat within the drying system. This reduces the energy required to heat up the continuous drying system before drying operations can be resumed.
- a corresponding drying module can be arranged at the beginning of the continuous drying system and another corresponding drying module can be arranged at the end of the continuous drying system.
- corresponding sliding doors can be arranged on both end walls of the drying module.
- the drying module can be designed as a chamber dryer, within which the desired drying is carried out completely with the sliding doors closed.
- a continuous drying system according to the invention for drying painted workpieces and/or painted assemblies, in particular painted vehicle bodies has at least two drying modules according to one of the above-mentioned configurations or a combination of at least two of these configurations with one another, which are relative to a direction of flow of the painted ones passing through the continuous drying system Workpieces or assemblies are arranged in rows with one another.
- the painted workpieces or assemblies are used dried by at least one drying air circuit generated exclusively within the drying module, which has at least one drying air blower arranged at least partially within the drying module and at least one electrical drying air heating device arranged at least partially within the drying module.
- drying module or the continuous drying system can be used according to one of the above-mentioned embodiments or a combination of two of these embodiments together to carry out the method.
