Definitions
- the invention relates to an atomizer (e.g. rotary atomizer) for applying a multi-component paint and an associated operating method.
- an atomizer e.g. rotary atomizer
- rotary atomizers are usually used as application devices, which in one design can also apply a multi-component paint that is mixed together in the rotary atomizer from a base paint and a hardener.
- a painting system is known, for example, from DE 102015010158 A1.
- the problem here is the collection of paint residues that occur, for example, when changing colors.
- wet washes One possibility for this is the use of so-called wet washes.
- the multi-component reactive paint material brought into the wet wash is filtered out of water using suitable chemicals (e.g. flocculation, floatulation), whereby the filter residue then has to be disposed of as hazardous waste, which is extremely time-consuming.
- suitable chemicals e.g. flocculation, floatulation
- VOC Volatile Organic Compounds
- the rotary atomizer is arranged, for example, over a rinsed collecting funnel or a collecting container, whereupon the residue of the multicomponent paint from the rotary atomizer can be rinsed out into the collecting funnel or collecting container.
- the rotary atomizer can first be moved into a collecting funnel or collecting container in order to rinse out paint residues of the multicomponent paint. The rotary atomizer can then be moved into a cleaning device in order to clean the outer surfaces of the rotary atomizer.
- DE 10 2009 020064 A1 discloses a painting system for painting one-component paint, a return valve actuated by its own medium enabling the return of color foam when there is a color change.
- the invention is therefore based on the object of creating a correspondingly improved atomizer and a corresponding operating method.
- the invention encompasses the general technical teaching of flushing paint residues of the multicomponent paint not in the direction of the application element (eg bell cup) from the rotary atomizer, but into a separate return.
- This offers the advantage that two process steps can take place simultaneously with a color change, namely on the one hand rinsing out residues of the multicomponent paint from the atomizer and on the other hand cleaning the outside of the atomizer.
- This enables the cycle time of the painting system to be shortened, ie the working speed is increased.
- the nebulizer according to the invention has various correspondence with the known nebulizers, as they are known per se from the prior art.
- the atomizer according to the invention also has a base paint connection for supplying a base paint and a hardener connection for supplying a hardener.
- a mixer in the atomizer according to the invention for mixing the base paint with the hardener to form the multi-component paint.
- a mixer is usually designed as a static mixer (e.g. lattice mixer, helical mixer).
- a hardener line runs in the atomizer from the hardener connection to the mixer.
- a master paint line runs in the atomizer from the master paint connection to the mixer.
- the atomizer contains a main valve known per se for controlling the paint dispensing, the main valve being arranged downstream behind the mixer and controlling the flow of the multicomponent paint to an application element (e.g. bell plate).
- an application element e.g. bell plate
- the atomizer according to the invention thus takes up hardener and base paint on the inlet side, mixes these paint components in the mixer to form a multi-component paint and then applies the multi-component paint to the component to be coated via the application element (e.g. bell plate).
- the application element e.g. bell plate
- the atomizer according to the invention is now characterized by a first return connection in order to return the multicomponent paint from the atomizer to a return, which takes place, for example, when a paint is changed, as will be described in detail below.
- a first return line runs in the atomizer and branches off in the atomizer between the mixer and the main valve and opens into the first return connection.
- the main valve is then usually closed so that no more multi-component paint is dispensed via the application element.
- the residues of the multicomponent paint still in the atomizer can then be passed via the first return line into the first return connection, which is usually connected to a return.
- the atomizer also has several main needle valves and several 2K May have returns.
- the atomizer according to the invention is preferably a rotary atomizer which has a bell plate as an application element, as is well known per se from the prior art.
- the invention can also be implemented with other types of atomizers, such as, for example, air atomizers.
- a downstream controllable first return valve and an upstream controllable second return valve which can preferably be controlled independently of each other. This offers the possibility of flushing medium being enclosed between the two return valves in the first return line in order to prevent a reaction between different mixed paint systems or to reduce it to a tolerable level.
- the nebulizer according to the invention preferably has a first flushing connection in order to supply thinner (flushing agent) and / or pulsed air.
- a first flushing line runs in the atomizer, which starts from the first flushing connection and opens downstream into the first return line behind the downstream first return valve.
- the return line provided according to the invention can therefore be flushed via this first flushing connection and the first flushing line proceeding therefrom.
- a first flushing valve is preferably arranged in the first flushing line in order to control the inflow of the diluent or the pulsed air from the first flushing connection into the first return line.
- the atomizer according to the invention preferably has at least one controllable hardener valve which is arranged in the hardener line and controls the flow of hardener.
- at least one controllable base paint valve is preferably provided, which is arranged in the base paint line and controls the inflow of the base paint.
- the atomizer according to the invention preferably has a second return connection in order to return the base paint separately from the hardener before it is mixed with the hardener.
- a second return line runs in the atomizer, which branches off from the base paint line upstream in front of the base paint valve and into the second return connection flows out.
- a controllable third return valve is preferably arranged, which controls the return flow of the base paint through the second return connection.
- the atomizer according to the invention preferably has a second flushing line which originates from a second flushing connection or from the first flushing connection and opens downstream into the main paint line downstream of the base paint valve.
- a second flushing valve is preferably provided, which is arranged in the second flushing line and controls the flow of flushing agent into the main paint line.
- a third flushing line is preferably provided, which emanates from a third flushing connection or from the first flushing connection or the second flushing connection and opens into the hardener line downstream behind the hardener valve.
- a third flushing valve is preferably arranged, which controls the flow of flushing agent into the hardener line.
- the hardener line and the base paint line can preferably be flushed independently of one another, the flushing agent supply being controlled in each case by a flushing valve.
- the nebulizer according to the invention can have a short flush line which leads downstream behind the main valve to the application element and from the first flush connection or from the second flush connection or from a third flush connection or from a further fourth flush connection goes out.
- this short-rinse line is preferably a controllable short-rinse valve that controls the flow of detergent through the short-rinse line.
- the atomizer according to the invention preferably contains a paint tube that contains the mixer and the upstream second return valve.
- the paint tube preferably also contains the main valve, which can be designed as a main needle valve and has a displaceable valve needle.
- the valve needle of the main needle valve is designed as a static mixer (eg lattice mixer, spiral mixer), ie the valve needle fulfills two functions here. For one, it serves the valve needle as a valve element to control the material flow. On the other hand, the valve needle also forms the static mixer.
- the upstream second return valve is designed as a diaphragm needle valve.
- the diaphragm needle valve has a valve seat and a displaceable valve needle which, depending on its position, releases or blocks the valve seat.
- a diaphragm needle valve is characterized by a valve diaphragm which surrounds the valve needle in a ring shape and serves to drive the valve needle and / or for sealing.
- Such diaphragm needle valves are known, for example, from WO 2009/019036 A1, so that the content of this patent application of the present description with regard to the structural design and the functioning of a diaphragm needle valve is to be fully attributed.
- the valve seat of the second return valve can consist of steel, while the Ventilna del of the second return valve can pass through a sealing washer made of plastic and can be made of titanium, for example. Furthermore, the mixer can open out on the outlet side into a distributor, which forwards the mixed multi-component paint and consists at least partially of metal.
- the main valve, the first return valve, the second return valve, the hardener valve and / or the master paint valve are also designed as membrane needle valves of this type.
- the invention not only claims protection for the above generally described atomizer according to the invention. Rather, the invention also claims protection for a corresponding operating method for such an atomizer, in which the base paint and hardener are supplied and mixed in the atomizer to form the multi-component paint, and then finally applied, for example via a rotating bell plate.
- the operating method according to the invention is characterized in that the multicomponent paint is fed back through the first return line when a color change occurs, which is between the Mixer and the main valve branches off.
- the residues of the multi-component paint are not released via the application element.
- the main valve (e.g. main needle valve) of the atomizer e.g. rotary atomizer
- the main valve (e.g. main needle valve) of the atomizer is preferably closed during the return of the multi-component paint.
- the following steps are preferably carried out to rinse the atomizer during a color change:
- the first flushing valve is then preferably closed and flushing agent is introduced into the first return line.
- flushing agent is introduced into the first return line.
- solvent and pulsed air are alternately supplied in order to achieve a good cleaning effect.
- solvent is then preferably added in order to partially fill the first return line with the flushing agent.
- the design of the nebulizer according to the invention enables the following steps to be carried out simultaneously or at least overlapping in time:
- Color change in the atomizer in particular with rinsing the atomizer into the first return line and pressing the atomizer with the new master paint and the new hardener.
