Definitions
- the invention relates to a coating installation for coating components with a coating agent, in particular in the form of a painting installation for painting motor vehicle body components with a paint.
- pneumatically driven paint supply pumps which are arranged in a paint supply space of the paint shop, are often used to convey the paint to be applied.
- These paint supply pumps are driven by means of compressed air, which is then removed from the paint supply pump via an exhaust air connection.
- One way of removing the exhaust air from the paint supply pumps is to deliver them via a silencer in the immediate ambient air.
- Another way of removing the exhaust air from the paint supply pumps is to collect them via air ducts in the paint supply room and then to lead them outside. In both cases, however, the exhaust air from the pneumatically driven paint supply pumps is no longer used.
- the invention is based on the technical-physical knowledge that the exhaust air of the pneumatically driven ink supply pumps is relaxed and cools due to the expansion.
- the cold exhaust air flow of the pneumatically driven pumps can therefore be used for cooling purposes.
- the invention therefore provides a cooling device which cools a heating sensitive component (e.g., railhouse) of the coating equipment by means of the cold exhaust air flow of the pump.
- a heating sensitive component e.g., railhouse
- the cooling device preferably has at least one first heat exchanger in order to transfer heat from the heating-sensitive component (for example, railhouse) of the coating installation to the cold exhaust air flow of the pump, whereby the heating-sensitive component of the coating installation is cooled.
- the heating-sensitive component for example, railhouse
- the cooling device preferably has at least one first heat exchanger in order to transfer heat from the heating-sensitive component (for example, railhouse) of the coating installation to the cold exhaust air flow of the pump, whereby the heating-sensitive component of the coating installation is cooled.
- a plurality of heat exchangers are connected in series.
- the first heat exchanger is an air / air heat exchanger, ie both the heat supply to the hot side of the heat exchanger and the heat removal on the cold side of the heat exchanger via an air flow.
- the first heat exchanger is an air / water heat exchanger, ie on the cold side of the heat exchanger, an air flow is passed through the heat exchanger, namely the cold exhaust air flow of the pump, whereas on the hot side of the heat exchanger, a water flow through the heat exchanger is directed.
- the heat exchanger is preferably a recuperator, i. a heat exchanger with an indirect heat transfer between cold side and hot side and a material separation between cold side and hot side.
- the cooling device has a cooling circuit, which connects the heating-sensitive component of the coating system to the first heat exchanger, wherein the cooling circuit contains a cooling medium (eg air, water), the heat to be dissipated by the heat-sensitive component of the coating plant to transport to the first heat exchanger.
- a cooling medium eg air, water
- the cooling medium is preferably conveyed in the cooling circuit by a pump in circulation operation.
- the heating-sensitive component of the coating installation can be, for example, a pipeline, for example a coating medium line or a paint line.
- a pipeline for example a coating medium line or a paint line.
- the cooling circuit is connected via a second heat exchanger to the respective coating medium line, wherein the second heat exchanger transfers the dissipated heat from the coating medium line to the cooling circuit, from where the dissipated heat from the first heat exchanger to the cold Abluftström the pump is transferred.
- the heating-sensitive component of the coating system is a so-called “railhouse”, i. around a protective housing surrounding a traveling axis of a robot (e.g., painting robot, handling robot).
- a robot e.g., painting robot, handling robot.
- Such "rail houses” are described for example in DE 102 34 915 AI and also belong to the general expertise, so that in this respect can be dispensed with a detailed description.
- the cooling circuit introduces cold air into the protective housing ("railhouse”) and removes warm air from the protective housing ("railhouse”) in order to lower the internal temperature of the protective housing ("railhouse”).
- the cooling of the compressed air used to drive the pump can lead to condensation or icing (icing) on the components of the system which come into contact with the relaxed, cold exhaust air of the pump can.
- the cold air line connected to the exhaust port of the pump is therefore provided on its outside with a heat insulation in order to avoid condensation or ice formation on the outside of the cold air line.
- the inventive idea of thermal insulation of the cold air line is independent of a cooling device of its own worthy of protection.
- the coating installation according to the invention preferably has a plurality of pneumatically driven pumps each having an exhaust air connection, the exhaust air connections of the pumps opening into a common cold air duct, which is preferably connected to the first heat exchanger.
- the pneumatic pump may be designed as a piston pump or as a diaphragm pump, however, the invention is not limited to these designs of the pump.
- the pneumatically driven pumps are preferably arranged in a paint mixing chamber of the coating installation, which is known per se from the prior art and therefore does not need to be described in detail. Furthermore, it is within the scope of the invention, the possibility that the cold exhaust air flow of the pneumatic pump can be passed without an intermediate heat exchanger directly to the warming-sensitive component of the coating system, which makes it possible to exploit the cold air of the exhaust without significant additional effort.
- the heating-sensitive component of the coating installation can be, for example, a pipeline or a so-called "rail house".
- Another example of the warming-sensitive component of the coating system is a paint booth.
- the cold exhaust air of the pneumatically driven pump can therefore also be used for cooling or air conditioning of Lackieranla ge, which can significantly reduce the energy consumption for air conditioning of the spray booth This is of particular importance because the energy consumption of a paint a large proportion of the total energy consumption of a motor vehicle plant.
- the invention also claims protection for the novel use of a cold exhaust air flow of a pneuma table driven pump for cooling a heating-sensitive component of a coating system.
- FIGS. 1 shows a schematic representation of a painting installation according to the invention with numerous pneumatically driven pumps, the exhaust air of which is used for cooling paint supply lines
- FIG. 2 shows a modification of FIG. 1, wherein the cold exhaust air of the pumps is used for cooling a so-called “railroad” will, as well
- Figure 3 is a cross-sectional view through a cold air line with a surrounding heat insulation.
- FIG. 1 shows a first exemplary embodiment of a painting installation according to the invention for painting motor vehicle body components, the painting installation being largely produced.
- grommlich is constructed so that it can be dispensed with a detailed Be ⁇ scription of the structure and functioning of the painting and are described in the following only the OF INVENTION ⁇ dung essential parts of the paint shop.
- the paint shop has several colored lines 1-5, in which paints of different colors are circulating promoted to prevent settling of the paints in the loops 1-5.
- the color guide lines 1-5 extend in each case through heat exchangers 6-10, which can be designed, for example, as a tube-in-tube heat exchanger and have the task of cooling the lacquer in the individual color guide lines 1-5.
- the heat exchangers 6-10 are connected to a common cooling circuit 11, which contains water as a cooling medium, wherein the cooling water is conveyed in the cooling circuit 11 by a pump 12 in circulation operation.
- the cooling circuit 11 extends through a further heat exchanger 13, wherein it is an air / water heat exchanger.
- a cold air line 14 passes through the heat exchanger 13, wherein the cold air line 14 is supplied by exhaust air ports 15-21 of several pneumatically driven ink supply pumps 22-28 with cold air.
- the ink supply pumps 22-28 can be designed in a conventional manner as a diaphragm pump or as a piston pump, so that it is possible to dispense with a detailed description of the ink supply pumps 22-28.
- the ink supply pump 22- 28 are preferably in a color mixing space of the paint at ⁇ sorted.
- the compressed air supplied via the supply air connections 29-35 compressed air is relaxed and thereby cooled, so that is discharged via the exhaust ports 15-21 cold air into the cold air line 14.
- the cold air then absorbs heat from the cooling water in the cooling circuit 11, whereby the temperature of the cooling water in the cooling circuit 11 is reduced.
- the heat exchangers 6-10 then transfer heat from the paint in the color guide lines 1-5 to the cooling water in the cooling circuit 11, thereby cooling the paint in the color guide lines 1-5.
- FIG. 2 shows a modification of the above-described embodiment according to Figure 1, so that reference is made to avoid repetition of the above description, wherein the same reference numerals are used for corresponding details.
- a special feature of this exemplary embodiment is that in this case a so-called railhouse 36 is cooled, ie a protective housing which surrounds a traveling axis of a robot (painting robot or handling robot) of the painting installation.
- the cooling medium in the cooling circuit 11 is air, so that it can be dispensed with in the embodiment shown in Fi gur 1 to zusurbanli ⁇ heat exchanger surfaces 6-10.
- the circulating in the cooling circuit 11 cold air is introduced into the railhouse 36 and thereby heated.
- the heated air is then returned to the cooling circuit 11 and cooled down again in the heat exchanger 13.
- Figure 3 shows a simplified cross-sectional view through the cold air duct 14, which is provided on its outside with a thermal insulation 37.
- the heat insulation 37 is intended to ensure that the outside temperature on the jacket surface of the thermal insulation 37, despite the low temperature of the cold air in the cold air line 14, is sufficiently large to prevent disruptive condensation or ice formation on the jacket surface of the thermal insulation 37.
