Definitions

  • Sprayers known with an atomizer head are provided with that under high hydrostatic Pressurized atomization material crushed and with is to be applied to a wall at high speed.
  • So DE 44 25 676 A1 describes a spraying device for viscous Building material mixtures consisting of a gun body and a removable spray head attached to this, in the inside of which is housed an air supply pipe.
  • Spray devices are also known which are used for atomization of very thin materials such as paints or Paints, are determined and in which the additionally introduced Air tearing and atomizing the liquids enables.
  • Such fine atomization as in thin materials, such as paints and varnishes, are desirable is, however, is when applying pasty masses, the one not have a high proportion of bitumen-water emulsion desirable because here the equilibrium of the emulsion by the strong tearing and atomization occurs and with it Can change properties of the sprayed material to be applied.
  • the task therefore is to put a sprayer in Gun shape for distributing and applying viscous to pasty masses with a high proportion of bitumen-water emulsion specify where a certain amount of air Tearing and dividing the compact spray material flow is achieved so that an even distribution on the Wall is possible, but the parts are not in one Aggregate form are transferred in which a change in Emulsion occurs.
  • a sprayer of the beginning mentioned type for distributing and applying viscous pasty masses which is characterized in that the Air metering tube arranged inside the spray head Is relatively adjustable in relation to the outlet mouthpiece, that the air metering tube in front of the outlet mouthpiece an air nozzle (18) ends, and that the outlet mouthpiece on the side facing the interior of the spray head is funnel-shaped and softly rounded.
  • a "thick material gun” is created, where the material is introduced directly into the spray head and there from the air through a 6 mm, for example wide nozzle can be applied.
  • This sprayer takes the spray material is not physically so demanding that it hitting the wall or another substrate no longer well distributed.
  • Air pressure can be above 100 bar, in particular up to 500 bar, can be used high material flow to and through the nozzle.
  • the liquid is divided far below one Atomization, leaving an excellent job application to.
  • a branch pipe is preferably attached to the spray head, which is removably attached to the spray material channel, preferably screwed.
  • the outlet mouthpiece is preferably on the spray head screwed on.
  • Different cross sections can be used the outlet openings can be selected. Has been advantageous a clear width with a diameter between 5 and 7.5 mm proven.
  • the sprayer has the typical technology well-known pistol shape. Indeed the spray material is viscous to pasty masses with a high proportion of bitumen-water emulsion.
  • Bitumen protective coating compositions are considered here the product name "Eurolan-1 (AIB)”, “Eurolanol”, “Eurolan-2”, “Plastikol-2 (AIB)”, “Eurolan-1 Flex "and similar products by the applicant.
  • the viscous to pasty masses are sufficient Pressure (5 to 15 bar) via a gun body fed.
  • the gun body 1 contains a spray material channel 2 in a corresponding hole.
  • the arrow P1 shows at that over a high pressure hose from a lifting frame over a corresponding suction device the viscous Material is brought up.
  • Using an operating lever 3 becomes a valve 4 engaging in the spray material channel 2 served.
  • a branch pipe 5 Starting from the valve 4 is a branch pipe 5, the The spray material is bent in an L-shape into a spray material storage cup 30 introduced within a spray head 10.
  • the spray head 10 ends in a narrowing Exit mouthpiece 11.
  • the exit mouthpiece is also 11 on the spray material storage cup 30 with the help of a Screwed cap nut 25. It is about at the outlet mouthpiece 11 by a hardened steel existing turned part.
  • the outlet mouthpiece 11 is on the inside of the Spray head 10 facing side funnel-shaped, the inner contour being designated by 12.
  • a contour a parabolic or hyberbel section is suitable, for example.
  • An air supply line 13 continues to be connected to the sprayer brought up to the rear end 14 of the spray head 10 is screwed tight. Before the L-shaped entrance the air line in the spray head 10 is still a throttle valve 15 provided with which the air supply line 13 cross-section is adjustable.
  • the air supply line 13 closes in the interior of the Spray head 10 an axially movable, in front of Exit mouthpiece 11 ends within the spray head 10 Air metering tube 19 at its tip in a Air nozzle leaks.
  • Air metering tube 19 is sliding tightly enclosed and can be relatively inside the spray head 10, can be adjusted. The adjustment can be made so far that it ends practically just before the outlet mouthpiece 11.
  • Compressed air is at a pressure via the air supply line 13 from above 50 bar, preferably between 200 and 500 bar, introduced.
  • the spray material is inside of the spray head 10 centrally in the area of the air nozzle 18 indented and from the air flow, the almost speed of sound has grasped, torn and out of the mouthpiece 11 shot out.
  • the spray material coming out of the outlet mouthpiece 11 is divided into pieces of approximately 0.1 cm 3 , so that it is divided into pieces of approximately 0.1 cm 3 , so that the emulsion is not broken, but remains until it is applied to the wall stops there and unites with the other particles to form a continuous coating.
  • the parts in which the air and the Spray compound are guided preferably without edges and corners is smoothly rounded, so that the fluids are free from turbulence can be performed.
  • the spraying material is applied before homogenized so that sharp-edged parts are eliminated.
  • the spray head 10 is screwed to the gun body 1.
  • a branch pipe is also attached to the spray head, which is removably attached to the spray material channel, preferably screwed on.
