Definitions

  • the invention relates to a device for producing foam according to the preamble of claim 1.
  • a device for generating foam in which the components forming the foam (foaming agent, water and air) are introduced into a large container in which the liquid components form a liquid level from which the foam bubbles rise and through the upper part of the container and a long foam line to the outlet mouths, for example for the foaming of motor vehicles in car washes.
  • the foaming agent i.e. a chemical substance that causes foaming and can also serve as a detergent.
  • a method for foaming liquids in which a foam generator consists of a container with a wire or fiber packing. From there, the foam is fed to a container via a line. With this device, a fairly good foam can be produced at least over a certain period of time, but it tends to do so already at the point of use to have lost in the foam quality.
  • WO-81/03 129 corresponding to EP-A-51 595
  • a mixing device for foam generation has become known, in which deflection chambers are present at the beginning and at the end of a tube, in which a right-angled deflection takes place and which is carried out with a metal or Plastic tangle are filled.
  • the object of the invention is to provide a device for producing foam, which produces foam with less expenditure on starting materials and in particular chemical foaming agents and releases it there in optimum quality.
  • outlet section is directly adjacent to the foam generator and the outlet mouth is arranged at a short distance from the outlet of the foam generator in the direction of flow.
  • the device has the advantage that the foam is generated almost at the point of use and is not deposited on the way there, in particular on the tube walls, and is torn apart and destroyed by the compressed air driving the foam in flakes.
  • the compact tubular and position-independent design makes it possible to bring the foam generator directly to the point of use of the foam.
  • All foam generation chambers can preferably be filled with the filling material.
  • This can preferably consist of a mesh or tangle of wire or preferably ribbon-shaped threads, in particular of plastic.
  • An embodiment is particularly preferred in which individual chambers are provided, the partition walls of which have openings, the opening area and / or number of which increase in the flow direction.
  • These chambers are filled with the filling material in the form of plastic mesh bodies stuffed into it. No liquid level needs to be formed in these chambers, but foam formation can begin practically immediately. Although it is possible to keep the inlet and outlet chambers free of the plastic braid, this is not absolutely necessary.
  • the numerous openings that form in the dividing walls and in the interstices of the braid have a foaming effect by wetting them with the liquid and the gas flowing through (preferably air) forms the foam bubbles from the liquid film.
  • only a half to a quarter of the amount of chemical foaming agents is required in a foam generator according to the invention.
  • the dosage of the foaming agent has hardly any effect on the washing performance. Due to the excellent quality of the foam, the essential effect, namely the good wetting and distribution on the washed surface and the damping of the mechanical action of the washing bristles, is largely independent of the amount of foam-forming agent.
  • the foam generator according to the invention is not only suitable for use in car washes, but also for other cleaning purposes, for example for cleaning buildings. Foams other than detergent foams can also be produced with it.
  • the foam generator can be brought close to the point of use in the invention, a re-collapse of the foam in the line under the pressure of the avoiding driving compressed air. This advantageously contributes to the fact that the foam generator is elongated, tubular and possibly has a zigzag or undulating course. The So to speak, foam is generated in the feed pipe without a large foam container connected upstream.
  • the foam generator is therefore not dependent on the position, ie it does not necessarily have to be arranged vertically.
  • a chamber can be arranged in a straight piece and a chamber in a bend, which are each separated from one another by partition walls with openings.
  • the entire foam generator can therefore consist of an only moderately strong plastic tube with a relatively large length (diameter / length ratio above 1:10 and preferably above 1:20).
  • Plastic pipes can be used which are welded or glued to one another with the interposition of intermediate pieces which hold or contain the partition walls.
  • the foam generator is advantageously arranged so close to the outlet mouth that the distance between the outlet of the foam generator and the outlet mouth is shorter than the flow path between the inlet and the outlet, and particularly preferably only half as large.
  • the outlet line is connected to an inlet connection of a distributor with a plurality of outlet orifices, the at least one distributor channel running transversely to the inlet connection has, in which at the junction of the inlet connection or overflow channels open, at least two outlet or overflow channels each being connected to each distribution channel at approximately the same distance from the junction points.
  • the foam coming from one line is distributed to two others by running about the same distance in the distributor channel to one side and the other.
  • Directionally adjustable short outlet nozzle pieces can be connected to the outlet orifices of the distributor.
  • the distributor with its distributor channels is preferably arranged horizontally, which ensures that the influence of gravity during distribution is switched off. However, a vertical arrangement is also possible.
  • the foam generator When the foam generator is arranged on a car wash, it can preferably be arranged directly on the pillars of a foaming device and practically spray directly from the upper part of the foam generator via the distributor.
  • the device preferably contains a metering and mixing device, the foaming agent being sucked out of a storage container by being contained in a state premixed with water.
  • the premix is sucked in by a feed pump, at the outlet of which a three-way valve which can be switched to form foam is connected, with a return branch and a feed branch, which leads to a mixing point for the production of the final dosage.
  • the device is also suitable for processing non-premixed products.
  • a plurality of foam generators arranged near the point of use can preferably be connected to a common metering and mixing device. In the invention, therefore, the individual components are transported close to the point of use and the foam is generated there, so that there are no long paths for the foam transport on which it could collapse again.
  • the device can be easily transported if a mobile use is desired.
  • the foam generator has a small volume and a small cross section and can only be connected to the metering device by means of very thin feed lines has many advantages.
  • the foam generator could possibly even be flexible, for example in a hose, and can have any cross-sectional shape. It is also advantageous that the finished mixture is already in the dosing and mixing device and the . Foam generator the ready mix can be fed through only one line, and that the foam generator is independent of position.
  • FIG. 1 shows part of a car wash 11 in which motor vehicles 12 are washed. For this purpose, they are towed by a transport device 13 (belts, chains or the like) through various stations, of which the foaming station 14 is shown. It consists of a fixed portal 15, which has the usual contactless sensors (light barriers or the like) for switching the corresponding devices on and off, and a foam generator 16 is attached to each of the two side rails.
  • a transport device 13 belts, chains or the like
  • It consists of a fixed portal 15, which has the usual contactless sensors (light barriers or the like) for switching the corresponding devices on and off, and a foam generator 16 is attached to each of the two side rails.
  • foam generator described below is also particularly well suited for mobile use, for example on car washes with a mobile portal (and a stationary car) or on building washes and the like.
  • the foam generators 16 are elongated tubular and arranged vertically in the embodiment. Their foam outlet orifices 17 lie on their upper part, while the foam components are supplied via lines in the lower part.
  • This finished mixture can be dosed very low with respect to the foaming agent, so that, for example, 0.3-0.4 cm 3 foaming agent per washed motor vehicle is sufficient. This is approximately a quarter of what was used in conventional systems and an even smaller fraction of what was used in conventional injector systems in which the foam was produced by mixing according to the Venturi principle.
  • Compressed air is supplied via line 19.
  • the control takes place in a metering and mixing device 20, which has a compressed air and water connection 21, 30, a feed line 22 from a storage container 23 and a return line 24 to the latter.
  • Fig. 1 shows in particular that the foam 25 can be sprayed practically directly from the foam images. It can be applied evenly to the motor vehicle from several outlet openings 17 per foaming agent, where it forms a uniform layer, which is good for Distribution and a hold of the wash-active substances on the surfaces to be washed, so that they do not run off immediately, and can be well distributed by the very soft brushes in the foam. It can also be seen that the outlet orifices can be adjustable, for example in order to enable uniform and loss-free foaming even when the motor vehicle is arranged asymmetrically under the portal.
  • the foaming agent is only connected via relatively thin lines for the mixture and air, which can optionally also be laid flexibly and in which distances from the metering and mixing device 20 play no role.
  • a dosing and mixing device can easily supply several foam generators. It can also be seen that the foam generators have a very small volume and can be easily inserted into systems.
  • Fig. 2 shows some essential parts of the metering and mixing device 20 in the circuit diagram. It contains two independently adjustable in the conveying performance, preferably driven by a common motor pump 26 via the supply line 22, a premix (for example in a ratio of foaming agent / water of 1/20) suck in and out of the reservoir 23 depending on a Dr eiwege- Feed solenoid valve 27, which are connected on the output side either to return lines 24 to the reservoir 23 or to a feed line 28.
  • feed line 28 for the premix opens into a water supply line 30 connected by a solenoid valve 29 which, after the premix has been mixed in from the feed line 28, forms the lines 18 for the finished mixture, each of which leads to a foam generator.
  • the compressed air supply line 22T also switched by a solenoid valve 31 and leads as compressed air line 19 to the foam generators 16.
  • regulating and non-return valves can also be arranged.
  • the foam generator 16 shown in detail in FIG. 3 consists of a plurality of plastic pipe pieces 34 which are connected to one another by connecting pieces 35, which have the shape of short pipe pieces 34 which cross over the pipe pieces 34 and which have a stop collar 36 on the inside.
  • the end faces of the pipe sections or partition walls 37, 37a, 37b defined by them are pressed against it and thereby fixed.
  • the connecting pieces are welded to the pipe pieces, so that the whole forms an elongated tubular unit, in which three long cylindrical chambers 38 are formed, while an inlet chamber 39 is connected to the lower end and an outlet chamber 40 is connected to the upper end.
  • These also consist of welded pipe sections which are closed with caps 41.
  • the inlet chamber has two inlet inclusions 42, 43 for the lines 18, 19 and is relatively short, while the outlet chamber 40 is longer and has in its central region an outlet line 44 extending at right angles from its circumference, which corresponds approximately to that of the chambers in cross section .
  • a foam distributor 45 through which the foam is distributed over three foam outlet openings 17.
  • the outlet line 44 does not branch off at one end but in the middle, so the distribution in the foam distributor is also carried out symmetrically on both sides (FIG. 6).
  • the foam distributor 45 thus has an inlet connection 46 connected to the outlet line 44 , which opens out in the middle of a distribution channel 47, which merges on both sides via elbows 48 into overflow channels 49, which in turn open into a longer distribution channel 50.
  • Symmetrical to the junction 51 in this distribution channel 50 are connected at its two ends and in the middle outlet nozzle pieces 52, which have the outlet openings 17 at their ends and each of two behind there are mutually connected 90 ° elbows 53 which can be adjusted via lockable coupling pieces 54 so that the preferably slot-shaped outlet mouth 17, which also connects via a coupling piece 54 and produces a fanned foam jet, can be adjusted in numerous directions (FIG. 3).
  • the foam distributor which is contained in a housing 55, like the foam generator, consists of welded or glued plastic pipe pieces, the distribution takes place symmetrically on both sides in order to have equal paths for the foam in all directions .
  • the foam is distributed in several stages (1 on 2 on 3), which also contributes to an even distribution over all outlet openings.
  • FIG. 3 to 5 show the partitions 37a, 37b. It can be seen that these dividing walls in the form of round disks have openings 56 which increase in number and size in the direction of flow 57, although the first dividing wall 37 can have a larger total opening area than the following ones. However, they adapt to the increasing development of foam.
  • the chambers 38 are filled with filling material 59, which in the exemplary embodiment consists of a loose tubular braid made of thin, monofilament band-shaped plastic wires or strips, which is drawn together in a torrent shape, so that it forms a disk-shaped body. Such meshes are commercially available as pot scratches. Filling the individual chambers 38 with this filler material by plugging them into the chambers has proven to be particularly advantageous.
  • porous filling materials can also be used which ensure that the liquid to be foamed continuously wets new elements provided with passages through the foam generator, as a result of which new foam bubbles are constantly formed.
  • the inlet and outlet chambers 39, 40 could also be filled with filler material.
  • FIG. 7 shows an embodiment of a foam generator 16a which can be produced by a zigzag-shaped arrangement with a shorter overall length, although in addition to the inlet and outlet chambers 39, 40 it has five chambers 38a, b which can be of different lengths.
  • one chamber 38a is formed by a straight piece of pipe, while the subsequent chamber 38b is formed by a 180 ° pipe elbow.
  • the connection is made as in Fig. 3 by connecting pieces 35 with inserted partition walls 37. This arrangement is suitable for installation in devices where the relatively flat foam generator can be attached to a wall. Spatial nesting could make the device even more compact.
  • partitions may be completely or partially replace the use of filler material, while on the other hand the filler material could also be held differently than by the partitions in the chambers.
  • the combination of partitions and the porous filling material is very advantageous, however, and above all it can be ensured that a desired throttling occurs in order to prevent the compressed air flowing in from blowing too easily through the entire tubular foam generator.
  • the facility In a car wash, the facility is operated so that when the car wash is put into operation, i.e. the starting of the basic devices, such as the drag belt 13, the pump 26, a continuously adjustable diaphragm pump, is started. It continuously promotes the premixing via the line 22 in the desired adjustable amount, however, as long as no foam formation is to be initiated, it returns via the three-way valve 27 back into the storage container 23, as a result of which the premixing contained therein is constantly circulated and segregation is avoided.
  • the basic devices such as the drag belt 13
  • the pump 26 a continuously adjustable diaphragm pump
  • the solenoid valves 27, 29, 31 are actuated at the same time, so that the corresponding ready mixture of water and premix is generated and transported via line 18 to the foam generator while Compressed air flows simultaneously via line 19.
  • the foam generator there is normally no level of liquid that would have to be monitored, as in the case of known devices, but the foam is formed immediately, its consistency is continuously improved as it passes through the entire foam generator and finally emerges, where it is only in the distributor 45 distributed and then output via the outlet nozzle pieces 52 directed in the correct direction.
  • Foam generation therefore takes place practically in the supply pipe to the point of use.
  • other parts for example the distributor, could also be included in the foam generator, in that they contain partition walls and filler material, or the distribution could be carried out in the foam generator.
  • FIG. 8 shows a detail of the inlet chamber 39, which can be used in both FIG. 3 or FIG. 7.
  • a check valve 70 is provided on the first partition 37, which consists of a seat housing 71 inserted into the partition 37, on which there is a suction strainer 72, and which inside carries a spring-loaded valve body 73.
  • the check valve 70 through the center bore of which the first foam generation chamber 38 is charged with the mixed components, prevents foam from pressing back into the inlet chamber from the foam generation chambers during downtimes. A defined and metered release of foam can thus be achieved.
  • the detail shown in FIG. 9 shows a support device 60 which is arranged in the foam generation chambers 38. This is also to be used advantageously in the embodiments according to FIGS. 3, 7 and 11.
  • the support device consists in each case of a cross strut 62 in the form of a four-pointed star (FIG. 10), which is kept at a distance from the next cross strut 62 by a central longitudinal connecting strut 64.
  • a transverse and longitudinal connecting strut 62, 64 are produced in the form of a unit 66 as an injection molded part and are plugged together with clamps and, if necessary, glued.
  • the longitudinal connecting strut 64 protrudes through a filler material body 59 which has the shape of a braid made of plastic strips, which is wound together to form a toroidal body, as is produced, for example, by the rolling of a hose.
  • Such tapes are commercially available as pot scratches.
  • the longitudinal connection strut is inserted through its central opening.
  • the support device 60 extends over the entire length of each chamber and ensures that, despite the considerable forces which the flowing foam exerts on the filling material, the filling material is not carried along in the direction of flow and is compressed at one end of each chamber.
  • the division of the chamber also ensures that the filling materials in the foam generator are stabilized, but this is further improved by the support device.
  • the packing density of the filling material preferably decreases in the flow direction 57, ie the packing density is greatest in the chamber immediately following the inlet chamber 39. This can be achieved in that the longitudinal connecting webs 64 of the support device are shorter there than in the rest of the foam generator.
  • Fig. 11 shows schematically that the foam generator, which in principle can be the same as that of Figs. 3 and 7, can serve directly as a handle for foam distribution in a portable device.
  • the foam generator 16b can be integrated into the outlet pipe because of its positional independence and its small cross-section, and the outlet mouth 17b can be attached directly to the head of the foam generator.
  • the foam generator is only connected to the device 20b via flexible hoses 42b, 43b, which, in addition to the devices shown in FIG. 2 (but only for a foam generator), can also contain the container for the foam generator, water and possibly an air compressor. It can be operated via a switch (e.g. pistol grip) on the foam generator itself, which triggers foam generation either electrically or by switching the liquids and gases directly.
  • a switch e.g. pistol grip
  • the foam generation in the device according to the invention is so good that even substances which were usually difficult to foam, such as preserving wax for lacquered surfaces, can be foamed so that they are in a liquid and mixed form with water Lacquered surfaces can be applied and, due to the slow collapse of the foam, can be deposited well on the lacquered surface without running ineffectively.
