Definitions

  • the invention relates to a spray gun for multi-component mixtures, in particular for two-component mixtures which react quickly with one another, with a grip piece and release lever, housing with connections for the component lines and with a mixing chamber attached to the housing with an associated outlet nozzle.
  • Spray guns are used to mix paint or similar liquid materials as evenly as possible. H. to apply in the form of a mist to a surface.
  • the aim is to atomize the materials to such an extent that they lay down as a correspondingly fine layer on the surface to be protected, and this in a layer thickness that is as uniform as possible. It becomes difficult when two-component mixtures that react quickly with one another are to be produced and then simultaneously applied to the substrate. This is because the two-component mixtures tend to mix when they are guided through the spray gun in such a way that a partially or completely cured material already results, with curing occurring in the mixing chamber or at the end of the mixing chamber.
  • the mixing chamber becomes clogged very quickly and then the spray gun if necessary, so that the entire components become unusable.
  • the same can occur in particular if the length of the mixing chamber has to be chosen accordingly in order to achieve a sufficient number of mixing processes. Attempts have been made to delay such hardening processes by high pressure of over 100 bar, but then spraying onto a flat surface is no longer possible due to the rebound effect.
  • the invention has for its object to provide a universally usable spray gun that can be adjusted to different spray mixtures without great expenditure of time and money, and also to quickly convert spray guns for blockers.
  • the object is achieved in accordance with the invention in that the housing is detachably connected to a structural unit comprising a mixing chamber and outlet nozzle and each has a check valve integrated into the supply lines between the connection and mixing chamber and only opening at a predetermined pressure, and in that the trigger lever assigned to the housing has a Switch in the housing of the supply pumps is simultaneously designed appropriately.
  • outlet nozzle can be exchanged for any kind of other outlet nozzles, always changing the mixing chamber, so that perfect conditions are always available for work.
  • the great advantage is in particular that it is ensured that the components that tend to harden are not brought together in the housing of the gun, but practically only in the mixing chamber, which in turn is releasably connected to the housing of the spray gun and is therefore easily replaceable.
  • further safety check valves are provided in the transition to the mixing chamber and are only set to open at a higher pressure than the upstream check valves.
  • the two check valves connected in series ensure that the necessary safe pressure builds up in the supply line before the two components can continue to flow. If one of the two non-return valves opens too early for whatever reason, the corresponding component comes then in front of the safety check valve to a standstill until the correspondingly higher pressure has built up, which also opens the safety check valve, whereby it can be assumed that this doubling of the check valves can compensate for errors, so that both supply lines open at the same time and the same Pour out components under pressure into the mixing chamber.
  • a sticking or even clogging of the supply line in the housing of the spray gun is also ruled out above all in that the safety check valves are arranged directly in front of the common inlet bore of the mixing chamber.
  • This special arrangement and design of the check valves ensures that the two components are only brought together outside the actual housing, so that this component is kept completely free of hardening components.
  • the junction is placed in the mixing chamber, so that this component, which is provided as a replacement part anyway, can be loaded without any problems.
  • the safety check valves are assigned to a housing attachment which is equipped with a middle piece which can be inserted into the mixing chamber and which has the safety check valves and an outer piece with an external thread.
  • a middle piece which can be inserted into the mixing chamber and which has the safety check valves and an outer piece with an external thread.
  • the assembly comprising the mixing chamber and the outlet nozzle is connected to the actual housing of the spray gun by means of a screw connection.
  • the housing attachment is provided with an external thread
  • the structural unit is assigned a correspondingly corresponding internal thread.
  • the invention provides that the structural unit has a mixing chamber and outlet nozzle receiving support tube which, on the side facing the housing, corresponds to its housing attachment and has an internal thread.
  • the mixing chamber and the outlet nozzle can thus consist of "disposable material" while the necessary forces or the necessary pressure are absorbed via the support tube.
  • the support tube can have a correspondingly small wall, so that the weight of the entire spray gun does not impair the ergonomics of the entire spray gun.
  • the mixing chamber and the outlet nozzle can consist of a material that is not of high quality and, above all, is not characterized by high weight.
  • the mixing chamber has a tubular jacket which can be inserted into the support tube and which is divided in the flow direction into a plurality of disk-shaped subchambers which alternately have a central and lateral preferably star-shaped inlet / outlet and with a large number of mixing elements, preferably balls are filled.
  • a mixing process of over 30 billion mixing processes can be achieved in a short way.
  • the two components are injected from above into the mixing chamber via the spray gun and then flow through several of the disk-shaped chambers that are filled with the balls, so that not only when changing from one disk-shaped chamber to the other, but especially through the balls filling the chamber, the necessary Mixing operations are enforced.
  • the individual subchambers are partitioned off from one another by partition walls, in which the central inlet / outlet or lateral inlet / outlet is alternately formed.
  • the components are forced to pass the balls from inside to outside or from outside to inside, the infinite mixing processes taking place.
  • other bodies can be used which have a correspondingly large area and ensure a division of the mixed material flow supplied.
  • each sub-chamber has been found to be expedient for each sub-chamber to have a layer of closely connected spherical mixing elements, in order to ensure that the ball flows around and the individual streams are divided and thus the two components are mixed.
  • the mixture is passed through the next central or side inlet / outlet into the next subchamber, where the mixing process is repeated as described, until finally the optimal mixture is at the end of the mixing chamber, for example, to be sprayed onto a well wall to become.
  • a star-shaped design of the partition is provided for side inlets / outlets.
  • the support tube is preferably made of suitable steel, while it is provided according to a further development of the invention that the mixing chamber including partition walls with central or side inlet / outlet and spherical mixing elements are made of plastic, the side inlet / outlet preferably by a star-shaped design of the Partition is specified.
  • this material is suitable because it allows the weight of the entire spray gun to be kept within limits.
  • the corresponding parts, which form the mixer chamber as a whole can be produced quickly and inexpensively. They can also be assembled easily and quickly and then placed as a complete unit in front of the spray gun, ie connected to it by screwing.
  • the structural unit can advantageously be integrated into the support tube, since the support tube has a funnel-shaped tip on the side facing away from the housing and correspondingly shaped with the outlet of the mixing chamber and / or the outlet nozzle.
  • the individual components of the mixing chamber including the outlet nozzle are first inserted into the actual mixing chamber from above and then as a complete unit in the support tube, without a connection then having to be made on the side facing away from the housing. Rather, the parts of the assembly which are filled into a bag are effectively fixed by screwing the support tube onto the housing or onto the housing attachment.
  • Trigger plunger is designed to act on the switch.
  • the trigger plunger acting on the switch is thus taken along by the plunger, which in turn is displaced in the direction of the switch by the trigger lever. Since this takes place against the force of the return spring, the release lever will snap back into its initial position when released, so that a safe dead man's switch is reached. With the plunger, the release plunger integrated in it is removed from the switch. This would complete the switching process and the supply pumps will be switched off. There is no danger to the person working with the spray gun.
  • the release plunger or the release plunger integrated therein is moved against the switch.
  • the release plunger carried out by the release lever is arranged and designed to act on the switch via an associated locking spring.
  • the trigger plunger is virtually double-secured or double-guided, so that it acts only “very slightly” on the switch without being able to damage it. This is mainly due to the built-in safety spring, but also the guide in the release lever, which is too high when pressure would cause the trigger plunger to slide through the trigger lever.
  • the invention is characterized in particular by the fact that a spray gun is created which is initially very easy to handle and is distinguished by a high level of safety during operation.
  • Two check valves arranged one behind the other ensure that the two components are always injected into the mixing chamber with the necessary and equal pressure, where they are quickly and repeatedly mixed with one another as they pass through the individual partial chamber, so that an optimal mixture is obtained from the outlet nozzle exit.
  • the second check valve is arranged so that the housing of the spray gun can not be affected by unforeseen curing of the two components.
  • the spraying process is initiated by actuating the release lever or by pulling it, whereby a dead man's switch ensures that the lever automatically moves back into its starting position when the pressure on the release lever decreases.
  • the switch which is correspondingly acted upon by the trigger plunger, is in turn adequately protected, so that continuous operation is possible without any problems.
  • This is mainly due to the fact that the mixing chamber and also the outlet nozzle, which form a structural unit, can be easily separated from the housing of the spray gun in order to be replaced by a new or different type. Since hardening cannot always be avoided in this area, any delays that may occur in the case of such disturbances can be kept low, but at the same time an exchange and replacement of the structural unit is also easily possible in this way, in order to be able to deal with the circumstances again easy to adjust.
