Definitions
- the invention first relates to a device according to the preamble of claim 1, as has become known for example from DE-PS 32 29 720.
- the invention is based on the object of expanding the field of use of such known devices, and this is achieved by the characterizing features of claim 1.
- the series connection of two nozzles is known per se, it is a special feature in combination with the separate liquid supply because so that each of the nozzles can be assigned a different function, which functions are to be carried out in succession.
- the first spray nozzle - in the working direction - provides pre-cleaning, for example with a lower pressure, whereupon the downstream second nozzle takes over, in a single operation, the post-cleaning, which is carried out, for example, with a higher pressure.
- devices of the generic type are operated under high pressure of at least 1000 bar and the like for cleaning ship hulls, buildings or concrete walls and the like. used.
- high pressure and the energy applied by the high-pressure pump lead to massive heating of the sprayed surface, which causes the residual water to evaporate rapidly or almost immediately or the treated surface to dry.
- this phenomenon can now be used to carry out a work step which is usually carried out separately together with the first if the training according to claim 2 is met. It is then possible to apply a new color primer immediately after cleaning.
- a spray housing 2 is fastened to a support frame 1, in which two spray nozzles 4 (FIG. 3) seated on arms 3 are rotatably mounted about an axis of rotation 5.
- the liquid feed line 6 also lies on this axis of rotation 5, i.e. that the rotary body formed by the arms 3 and the spray nozzles 4 is expediently mounted about a hollow axis forming the feed.
- this is sealed on its lower, open side facing the surface 7 to be sprayed by a concentric sealing apron, which is expediently formed by a row of bristles 8 (see FIG. 2).
- Rollers 9 are attached to the support frame 1 to determine the working direction. In this way, the carriage 1, 9 thus formed can be moved according to FIG. 1 either in a working direction A or in a working direction B. All parts described so far are state of the art.
- fastening devices 11 are attached to the support frame 1 at the front and rear.
- Figures 2 and 3 show that there are actually a pair of fastening devices 11a, 11b.
- spray nozzles 12 designed in the manner of spray guns can be fastened to the support frame 1, the spray jet of which runs along the spray axes 13 in the manner shown in FIGS. 1 and 2.
- the fastening devices 11a, 11b expediently hold the associated spray nozzles 12 on a line running transversely to the working direction.
- at least one of the fastening devices is preferably provided with an adjusting device.
- the adjustment device has a plate 14 for rough height adjustment (and thus for the rough adjustment of the sprayed surface area), which is provided at intervals with fastening recesses 15, via which the plate 14 can be fixed to a stand 16.
- a fine adjustment can also be provided.
- the angle of inclination of the spray axis 13 to the surface 7 to be sprayed can be set by known measures which are not explained in detail.
- the distance of the jet of the nozzles 12 from the spray housing 2 can thus also be set if there are differences in the drying time.
- the supply of the liquid or paint to the spray nozzles 12 is expediently carried out by hoses placed on a supply nozzle;
- the atomizing air can be supplied via a transverse bore (not shown) in the nozzle flange or on a nozzle head.
- the nozzle 12 each can be closed by a nozzle needle, which may also be remotely operated (via a corresponding motor).
- the rotating nozzles 4 which are driven in the manner of a Segnerian waterwheel, are supplied from a water reservoir by a high-pressure pump via a line connected to the feed connector 6 (or the hollow axis), the nozzles 12 are preferably at a pressure which is substantially lower ( line under 500 bar, in particular 100-300 bar) connected to a correspondingly smaller pump that delivers from a paint reservoir. While the first pump generates a pressure in the range from 1000 to 3000 bar, in the case of the second pump it may only be 100-300 bar.
- the support frame 1 together with the spray housing 2 and its parts can be produced in relatively large numbers, because where there is a need for equipment with further spray nozzles 12 on the front and / or rear side (for changing the working direction ) results, the support frame 1 can be easily provided with these. For this purpose, only the fastening devices 11 and the nozzles 12 are then to be attached.

Claims (10)
1. Dispositif pour soumettre une surface à une pulvérisation, comprenant au moins une première buse de pulvérisation qui est montée tournante en pouvant être entraînée autour d'un axe de rotation, qui est alimentée en liquide sous pression et qui est disposée dans un carter de pulvérisation, lequel peut être déplacé au-dessus de la surface à soumettre à la pulvérisation dans une direction de travail prédéterminée, caractérisé par le fait qu'au moins une autre buse de pulvérisation (12) est disposée derrière la première buse de pulvérisation (4) - dans le sens de la direction de travail -, et qu'elle comporte une amenée de liquide (29) séparée de la première.
2. Dispositif selon la revendication 1, caractérisé par le fait que l'autre buse de pulvérisation (12) constitue la buse de pulvérisation d'un dispositif réalisé à la manière d'un pistolet de pulvérisation.
3. Dispositif selon la revendication 1 ou 2, caractérisé par le fait que l'autre buse de pulvérisation (12) est fixée derrière la première buse de pulvérisation (4) à l'aide d'un dispositif de fixation (11) détachable de manière non destructive, et qu'elle est réglable, de préférence, par l'intermédiaire d'un dispositif de réglage, et en particulier d'un dispositif de réglage grossier et de réglage fin.
