Definitions
- the present invention relates to a device for receiving workpieces to be subjected to a surface treatment, in which gases and / or vapors to be removed arise, which device has a tub with an interior for receiving the workpieces to be treated and a tub cover which is between an open position and a has device that contains an inlet area and is designed on the outlet side for connection to a suction source of gases or vapors.
- gases and / or vapors are generated which must not be released directly into the environment. These gases and / or vapors are drawn off and disposed of by appropriate plant parts. As is well known, considerable amounts of air are also sucked out. The amount of air drawn off must obviously be replaced by an equal amount of supply air, which must be brought to a predetermined temperature, which temperature is such that the supply air must be heated except during the warmest season. This heating obviously means a considerable expenditure of energy. Further emerges due to the relatively large amount of air circulated and also due to the wind speed, for example on the surface of the bath, a loss of evaporation, which is very pronounced, for example, in electroplating systems.
- the invention seeks to remedy this.
- the invention as characterized in the claims, achieves the object of providing a device for receiving workpieces to be subjected to a surface treatment, in which the tub cover forms a section of the flow channel device and there are no structural members on the tub inner walls for connection to the suction source .
- the advantages achieved by the invention are to be seen essentially in the fact that the amount of exhaust air is considerably reduced, a high saving in energy for heating the treatment medium is achieved by the steam pressure in the respective tub can be kept higher than before.
- the much smaller amount of exhaust air can result in smaller ventilation systems with a corresponding further energy saving.
- the MAK value can also be maintained and pollutant emissions can also be greatly reduced.
- the reference numeral 1 denotes the tub in which the respective goods are subjected to a surface treatment.
- the tub 1 is closed at the top by a lid.
- This cover is basically composed of an upper plate 2 and a lower plate 3, which plates 2, 3 enclose a space 9 between them.
- the cover formed from the two plates 2, 3 is firmly connected to a hollow shaft 7, so that the cover 2, 3 can be pivoted between the (drawn) closed position and an open position by rotating the hollow shaft 7.
- the hollow shaft 7 accordingly has an interior 8.
- the upper plate 2 is flat and the lower plate 3 is bowl-shaped.
- the lower plate 3, viewed in cross section has an angled edge region.
- the lower plate 3 has a section 4 which runs parallel to the main surface of the lower 3 or upper 2 plate of the cover and serves as a support section 4 of the entire cover on the tub edge 5.
- This support section 4 is followed by a plate section 12 running at right angles thereto, which runs at a small distance from and parallel to the tub inner edge section 11 opposite it.
- This described formation of the edge of the lower Plate 3 is formed at three edge regions of the square plate, the fourth edge region, as shown, being firmly connected to the hollow shaft 7.
- the space 9 of the cover 2, 3 is connected to the interior 8 of the hollow shaft 7 via passages 34.
- the reference number 35 denotes a seal that is possible here, but not available in all systems. Connection.
- the reference number 35 denotes a seal that is possible here, but not available in all systems.
- FIG. 2 shows a view in the direction of arrow A in FIG. 1.
- the hollow shaft 7 is closed on one side (in FIG. 2 on the left) and connected to a drive 36, by means of which the cover is pivoted up and down.
- This drive 36 can take any form, it can be an electric motor drive, a hydraulic or pneumatic drive.
- the hollow shaft 7 is designed for connection to an exhaust air line 37, which leads to a suction source 32.
- the hollow shaft 7 is permanently connected to the exhaust air duct 37, with any known measures being taken with regard to the sealing between the rotatable hollow shaft 7 and the fixed exhaust air duct 37.
- the operation of the device shown is as follows. It is assumed that the goods in the tub are used for any surface treatment, with gases and / or vapors developing depending on the particular treatment. These are now trying to emerge from the tub, for example under the influence of temperature. A flow thus forms through the gap 13 between the plate section 12 and the tub inner wall section 11. This gap 13 sets in the flow first resistance to. The flow continues through the section 6 between the support section 4 of the lower plate 3 and the tub rim 5. Since there are usually no seals here (or may be for reasons of corrosion, for example), the gases and / or vapors can escape through this section 6. Incidentally, designs are also conceivable in which there is a small distance between the support section 4 and the tub edge 5.
- the gap 13 forms, together with the section 6, a flow resistance section similar to a labyrinth seal, so that a resistance is opposed to the outflow.
- the exhaust air volume can be reduced to 5-10% of the previous exhaust air volume, with the result that the exhaust air system can be much smaller, the cleaning systems including their energy requirements are much smaller, the supply air system including the energy requirement for the supply air blower becomes smaller and the heat exchanger for heating the supply air and the energy requirement for this supply air heating is also greatly reduced.
- the support section 4 of the lower plate 3 is further back than the edge of the upper plate 2.
- the edges of the two plates 2, 3 can be aligned with one another.
- the gases and vapors sucked into the intermediate space 9, including the air also sucked in from the environment, flow through passages 34 in the hollow shaft 7 into the interior 8 thereof and from there, as indicated in FIG. 2, through the exhaust air line 37 to the suction source 32
- the cover and the hollow shaft thus form the flow channel device for the exhaust air. There are no suction components in the interior of the tub 1.
- the suction hood 16 has a suction nozzle 17.
- a suction line 38 is assigned to this suction nozzle 17, which also leads to the suction source 32. Since the goods carrier can be moved by the converter with its suction hood 16 over the various treatment troughs, a temporary connection between the suction nozzle 17 and the exhaust air line 38 is created in a respective position of the suction hood 16 via a respective trough 1, which temporary connections in general in such systems are known.
- the position of the lower edge 18 of the side wall 19 of the suction hood 16 is selected in relation to the opened cover such that a small gap 20 is present between the edge of the cover with the entry area 33 and the lower edge 18 of the side wall 19. This gap 20 generates an air flow from the environment into the suction hood 16 during suction through the suction nozzle 17, so that the gases and / or vapors cannot escape.
- a plate 23 stands up from the tub rim 21.
- the dimensions are chosen such that the lower edge 24 of the corresponding side wall 25 of the suction hood 16 and the upper edge of the plate 23 again have a gap 26 through which the air flows from the surroundings into the suction hood 16.
- the narrow side of the suction hood 16 facing the viewer and facing away from the viewer is pulled down to such an extent that there is also a small gap between the tub rim and its lower edges, through which an air flow takes place inside the suction hood 16.
- FIGS. 1-3 only a cover is present.
- versions with two lids according to FIG. 4 are also provided. This means that the system has a reduced height.
- the suction source 32, the suction nozzle 17 and the suction hood 16 with the side walls 19 and 25 are drawn again.
- the tub 1 there are now two lids 29, 30, which are also constructed from an upper plate 2 and lower plate 3, which are connected to the hollow shaft 7 are connected for pivoting.
- the difference between these covers 29, 30 and the only cover of the previous figures is that the facing edges of the covers 29, 30 (seen in the closed position) can each have a longitudinal bar 14, 15.
