Definitions
- the present invention relates to a method and a system for coating, in particular, difficult-to-access bodies, such as radiators, and a method and a system for introducing viscous or pasty masses into difficult-to-reach places, such as in building penetrations.
- a large number of devices for example industrial systems with radiators or pipe systems, have to be provided with a new coating, such as a new paint, on their outside from time to time.
- This varnish can have an optical, but also a corrosion-inhibiting function, for example.
- the devices mentioned have in common that they are generally only accessible from one side when installed in a corresponding system. Access from the other side is blocked, for example, in the case of built-in radiators by a wall located at a short distance, or in industrial systems containing pipe systems by other machine components.
- a new coating of the devices mentioned has therefore been a certain problem for a long time.
- radiators It is known to dismantle radiators to be coated from the heating system and from the adjacent wall and then to coat them again.
- the coating can be carried out, for example, by an immersion bath or by a spraying device.
- the removal and the subsequent installation after the coating is an essential time and cost factor of the entire coating process.
- radiators for example in the course of apartment renovations, have to be regularly repainted, that is, repainted.
- the installation and removal of radiators in apartments to be renovated presents the further problem that during installation and removal, for example, the parquet or carpeting near the radiator must not be affected by leaking liquid from the removed radiator.
- the re-coating of the radiator can be carried out in the installed state, that is to say, for example, mounted on a wall.
- it is known to paint the radiator in the installed state to provide it with paint by means of a roller device or to spray it.
- paint the radiator in the installed state to provide it with paint by means of a roller device or to spray it.
- the object of the present invention is therefore to create a coating method and a coating system, in particular for radiators, in which a satisfactory coating can be achieved with little effort.
- a method or a system is provided to achieve the stated object, in which the coating liquid, for example radiator paint, is applied without pressure to the body to be coated and is then returned.
- the coating liquid for example radiator paint
- feedback is to be understood to mean that coating liquid which runs off or drips off the body to be coated is either fed into a container or back into the circuit and can thus be used again.
- a method for coating radiators in particular is provided, in which a coating liquid is applied without pressure to a body to be coated. The unpressurized application of the coating liquid takes place in a surge-like manner so that the coating liquid is applied to the body in excess. The excess coating liquid running off the body to be coated is then collected, suctioned off and returned.
- a flood gun in the sense of the present description is a device through which a liquid supplied by means of a hose can be dispensed without pressure.
- the suctioned off coating liquid is advantageously returned to a storage container by a suction pump. It can then be guided from the storage container to the flood gun by means of a feed pump.
- the heater is advantageously coated in the installed state.
- a solvent-based lacquer or an acrylic-based lacquer can be used as the coating liquid.
- an exchangeable coating tube with a length and / or an inner diameter can be inserted into the gun which is selected depending on the shape of the body to be coated. This means that if, for example, the radiator to be coated has a particularly large expansion in the depth direction, a coating tube with a long length can be inserted into the flood gun.
- a coating system is also provided, in particular for the color coating of radiators.
- the coating system has a device for applying a coating liquid without pressure.
- the pressure-free application ensures that no paint mist that is harmful to the user and the surrounding wall or floor surfaces occurs during the application. At least part of the applied coating liquid can then be collected in a collecting container. The coating liquid can then be returned by means of a system.
- a flood gun is particularly suitable as a device for applying the coating liquid without pressure.
- the return system can have a return pump for returning the coating liquid from the collecting container to a storage container and a feed pump for supplying the coating liquid from the storage container to the flood gun.
- the suction pump, the reservoir and the feed pump can be arranged on a mobile base frame. This means that a compact and mobile mini color coating system for radiator coatings can be created.
- a replaceable coating tube can be provided, which can be screwed onto a thread with a seal of the flood gun.
- the coating tube can be selectable from several coating tubes with different lengths, different shapes and / or different inside diameters, the type of coating tube to be selected depending on the shape of the body to be coated.
- a flexible coating tube in the manner of a hose can also be provided.
- the coating liquid can be a solvent-based lacquer or an acrylic-based lacquer.
- the coating method or coating system according to the invention thus has the advantage over conventional coating systems, in particular for radiators in the installed state and other difficult-to-access bodies in the installed state, that a surface of the body to be coated is recoated in a high-quality and environmentally friendly manner without much time and effort can.
- the further object is achieved in that the mass is conveyed from a storage container while exerting pressure to an output end of a delivery line designed in the manner of a flood gun and is output there.
- the mass to be conveyed is preferably a leveling compound or a fire protection material such as Pyroplast-C.
- a return line is expediently provided in order to return mass to the storage container when the valve is closed or partially closed.
- a mass reservoir is provided and a pressure applying device for applying pressure to the mass to convey it to the discharge end of the delivery line.
- the pressure application device can be formed on the one hand by a self-priming pump at the outlet of the storage container and on the other hand by a prestressed pressure element in the storage container. Both types of pressure application device are expediently provided. If the self-priming pump is provided, the return is expediently carried out against the action of the prestressing of the pressure element, provided that this is provided in the storage container.
- both embodiments of the invention can be designed to be compatible with one another in such a way that the reservoir of the coating system can be retrofitted with a pressure element if required, that is to say can be replaced again, and that the feed pump for the coating liquid is simply replaced by a suction pump for the viscous or pasty mass is replaceable. Then, with a single shared system on a construction site, both radiators and other difficult-to-access traction elements can be coated in the installed state, and, in the meantime or in succession, fillers and fire protection materials can be applied to the intended locations or applied to the body there.
- FIG. 1 shows a side view of a system according to the invention for coating radiators in particular
- FIG. 2 shows a top view of a system according to the invention for coating radiators in particular, this view in particular the circular one
- FIG. 3 shows a flood gun of a system according to the invention for coating radiators in particular
- 4 shows a side view and a top view of a collecting trough according to a system according to the invention for coating radiators in particular
- FIG. 5 shows another system according to the invention for introducing heavy or pasty masses in places that are difficult to access
- FIG. 6 shows an example of the use of the system according to FIG Fig. 5.
- FIG. 1 3 is shown schematically in the sense of a block diagram, a so-called ' flood gun.
- a flood gun is a device which is supplied with a liquid by means of a feed line 12 so that this supplied liquid can be applied.
- the pressure on the inlet side of the flood gun 3 is dimensioned such that it is just sufficient to let the liquid emerge on the outlet side 11 of the flood gun 3.
- a coating liquid is applied to a radiator 10 by means of the flood gun 3.
- the coating liquid in the present case paint or varnish, is applied in a flood-like or gush-like manner by the flood gun 3.
- paint or varnish is applied in excess to the surface of the radiator 10, so that part 23 of the applied paint or lacquer drips on the underside of the radiator 10 to be coated and in a collecting trough 5 which is arranged below the radiator 10 is can be collected.
- a continuous flow of the coating liquid is thus generated on the surface of the radiator 10.
- a high-quality coating of the surface of the radiator 10 is achieved, that is to say the coating liquid is applied in excess to the surface of the radiator 10 to be coated for a certain period of time, and thus the surface of the radiator 10 is flooded for a certain period of time.
- a high quality, that is, smooth and homogeneous coating of the surface of the radiator 10 can be achieved without a so-called nasal formation, without impairing the environment, as in the prior art of Tecrinik, for example due to odor and paint mist or contamination of the surrounding area Wall and floor surfaces is caused.
- the heater 10 can thus be coated in the installed state, that is to say in the state in which it is attached to the heating system and to the corresponding wall, without there being any risk to the user or the surrounding surfaces. Due to the surface tension of the coating liquid flooding application of the coating liquid from above the radiator also sufficiently downward-facing areas of the surface of the radiator 10, that is to say the coating liquid pulls itself onto these downward-facing areas due to its surface tension.
- Figure 1 it is shown that a first rib of the radiator 10 is coated. If after a certain period of time that the coating liquid flows over the first rib of the radiator 10, the first rib of the radiator 10 is coated satisfactorily. the flood gun 3 can be moved in the direction of the second rib of the heating element 10 in order to coat this as well, etc.
- the storage container 1 can be, for example, a conventional paint container with a volume of, for example, 10 liters. Its volume is such that there is sufficient buffering of the coating liquid for the entire circuit.
- the coating liquid buffered there is then fed back to the flood gun 3 via a line 21 by means of a feed pump 2 and a feed line 12.
- the feed pump 2 is also driven by an electric motor 6 and by a controller 7.
- the motor 6 for the suction pump 4 and the motor 6 for the feed pump 2 can be switched independently of one another, so that the suction pump 4 and the feed pump 2 can be operated independently of one another.
- the system flood gun 3, drip pan 5, return line 19, reservoir 1 and feed line 12 creates a practically closed circuit. According to the invention, there is therefore no loss of coating paint which is detrimental to the environment, as is the case, for example, in the prior art for spray processes.
- Feed pump 2, the suction pump 4 and the reservoir 1 on a base frame 9 be attached, which is provided with wheels 8 so that it is mobile.
- the coating system according to the invention can thus coat radiators 10 on site, which do not have to be removed for coating.
- the circuit-like guidance of the coating liquid can be seen particularly well in FIG.
- the recirculated part 23 of the coating liquid from the collecting trough 5 can of course also be returned to the flood gun 3 by means of the pumps 4, 2 or only with one of the two pumps.
- Prerequisite for this is only that in this circuit in the coating liquid • cycle is available with direct feedback always sufficient, so that a sufficient flooding the radiator is ensured 10th
- the buffering can be formed by the volume of the drip pan 5. This possibility of the direct return of the coating liquid from the collecting trough 5 is shown in dashed lines in FIG. 2 and designated by 24.
- a flood gun 3 which can be used in the system or method according to the invention for coating radiators in particular.
- the flood gun 3 is supplied with a liquid via the feed line 12.
- the flood gun has a handle 13, which is more or less ergonomically designed so that the fingers of the hand of the user holding the flood gun 3 can include a gun-like valve handle 14.
- a valve 15 is opened.
- coating liquid supplied through the feed line 12 can escape at the downstream end 11 of the flood gun 3.
- the extension pan 18 can be completely inserted into the base pan 17 for transport.
- the extension pan 18 can be retracted into the base pan in such a way that no coating liquid can escape to the outside.
- the coating system according to the invention can advantageously be operated with a solvent-based radiator paint or an acrylic-based radiator paint.
- a coating system and a coating method, in particular for radiators are thus created, by means of which surfaces of a body which are to be newly coated can be coated in a time-saving manner without dirt expenditure and with little expenditure of time because of the unnecessary expansion of the body to be coated and in an environmentally friendly manner. Surrounding surfaces are not contaminated during the coating process according to the invention.
- a particular advantage of the invention is that one of several coating tubes 20, 26 can be screwed onto the thread 16, and the replacement of a coating tube 20, 26 can even take place during the operation of the coating system according to the invention.
- the various screw-on coating tubes 20, 26 differ in their shape. That In order to coat inaccessible places on the surface of the body to be coated, the coating tubes can be straight as shown in FIG. 3, but also curved or kinked. The different coating tubes also differ in their length and their inner diameter.
- the coating tube designated 26 in FIG. 3 is particularly long and has a small inside diameter.
- Fig. 4 shows a particularly advantageous embodiment of the drip pan 5.
- the drip pan 5 consists of a base pan 17 and an extension pan 18.
- the extension pan 18 is displaceable in the base pan 17.
- the pull-out area of the extension tray 18 is also suitable for the introduction or application of viscous or pasty masses in places that are difficult to access, such as in building leadthroughs.
- Fig. 6 shows schematically such an arrangement consisting of a building ceiling 40, for example made of concrete, and a building wall 41, for example a goat masonry.
- the building ceiling 40 has an opening or a passage 42 in which cables and lines 43, insofar as shown schematically in FIG. 6, are laid.
- the passage 42 is to be filled completely with a viscous (low-viscosity) or pasty mass without any cavities. It can be a so-called leveling compound or a fire protection material such as Pyroplast-C.
- This compound can now be applied by means of a dispensing device in the manner of a flood gun 3, as has been explained above in particular with reference to FIG. 3. This is explained in more detail using the system shown in FIG. 5.
- the viscous or pasty mass 37 is first filled.
- a pressure element 31 formed by a plate is then placed on the mass 37 in the reservoir 29.
- this pressure element 31 carries a biasing element 32, which is preferably formed by one or more springs.
- the lid 30 of the reservoir 29 is closed, for example by pivoting about a hinge, and locked, for example by engaging a closure element 36 on the reservoir 29 in a hook 35 on the lid 30.
- the mass 37 is then applied via the coating tube 34, which is preferably designed in the manner of a flexible hose, and a dispensing attachment 39 of the coating tube 34.
- the mass can be safely introduced into the feedthroughs 42 without losses and without voids. This ensures a complete filling of both the leadthrough 42 and a complete coating of the cables and lines 43, which is particularly important in the case of cables and lines to be provided with fire protection materials or bushings 42 to be filled with fire protection materials.
- the delivery of the mass can also be achieved in that a suction pump 27 driven by a motor 28 is provided in the discharge line 38.
- a return line 33 is to be provided in order to be able to return mass 37 conveyed by the suction pump 27 to the reservoir 29 when the valve is closed or partially closed. Since the prestressed pressure element 31 and the driven pump 27 can also be provided together, in such cases it is expedient to pass the return line 33 into the mass 37 in the reservoir 29, i.e. past the pressure element 31, which is shown in FIG. 5 is shown schematically.
- the system shown in FIG. 5 can expediently also be provided on a base frame 9 provided with wheels 8, as is explained with reference to FIGS. 1 and 2.
- 5 can be provided on the same base frame 9 as the system of FIGS. 1 and 2.
