Definitions

  • the present invention concerns an apparatus and a method for tempering a liquid surface treatment agent, as well as use of the apparatus. More particularly, the invention concerns an apparatus and a method for tempering a liquid surface treatment agent which, prior to the application thereof onto a surface, is located in a receptacle, and wherein the tempering is effected by means of at least one pressurized air element.
  • the object of the present invention is to provide an apparatus for tempering a fluid, in which the apparatus is simple, technical speaking, and may be carried by only one person, and which only requires pressurised air for the operation thereof.
  • pressurized air element implies a device known per se arranged to be able to provide a temperature change in a fluid, for example air, flowing through the device, in which the temperature change is provided as a result of the flow conditions in the device .
  • a fluid for example paint
  • a fluid becomes difficult to apply to a surface when the temperature of the paint falls below a certain temperature. This temperature depends on the viscosity of the fluid. It becomes particularly difficult to apply paint by means of e.g. a spray gun, which is run on pressurized air, when the temperature is too low / the viscosity is too high.
  • Apparatuses arranged for application of marking stripes onto roads and pavements, in which quick-drying paint is required are known from American patent publications US 6,183,161 and US 4,190,205. Prior to applying the paint onto the road via a high-pressure nozzle, it is warmed up by flowing through a pipe system affected by the warm exhaust from a combustion engine .
  • An apparatus for application of paint in which the paint is pumped through a pipe system in a heat exchanger, is known from PCT-application with publication number WO 2004/108300. Warmed up and pressurized air, which discharges from an application device together with the paint heated by the warmed up and pressurized air, is put through the heat exchanger.
  • WO 2004/108300 describes an apparatus capable of pumping paint out of a paint receptacle and through a heat exchanger, thereby being warmed up immediately prior to applying the paint onto a surface.
  • the apparatus is relatively complex and does not offer the possibility of warming up the paint when located in the receptacle.
  • the apparatus requires the paint to be applied by means of e.g. a paint spray gun.
  • the object of the invention is to remedy or reduce at least one of the disadvantages of the prior art.
  • a first aspect of the present invention provides an apparatus for tempering a liquid surface treatment agent, such as paint, located in a receptacle, wherein the tempering is effected by means of at least one pressurized air element.
  • a second aspect of the present invention provides a method for tempering a liquid surface treatment agent, such as paint, located in a receptacle, wherein the method includes affecting the surface treatment agent by means of the temperature of air discharging from at least one pressurized air element having air supplied thereto from a pressurized air source .
  • a third aspect of the present invention concerns use of a pressurized air element for tempering a liquid surface treatment agent .
  • Fig. 1 shows a perspective front elevation, as viewed aslant from above, of a pressurized air element placed in fluid communication with a chamber defined by a box of rectangular shape, in which the box encloses a portion of a pail of paint;

  • the source of pressurized air may be a compressor for providing so-called work air intended for supplying air-operated hand tools.
  • the pressurized air element 3 is provided with two outlet portions 7, 7' for air being warmer and colder, respectively, than the air supplied from the source of pressurized air.
  • FIG. 1 shows a principle sketch of an apparatus according to one embodiment of the present invention.
  • the apparatus 1 is comprised of a rectangular box 9 provided with a removable top portion 11.
  • the top portion 11 is provided with two cut- s outs 13, each of which is arranged for receiving e.g. a pail 15 of paint.
  • a paint pail 15 is placed in only one of two cut-outs 13 of the top portion 11.
  • the cut-out 13 not used is provided with a substantially sealing lid 13' .
  • One of the advantages of a removable top portion 11 is that it is possible to provide one box 9 with top portions 11 adapted to the dimensions of those receptacles or paint pails 15 to be tempered in the apparatus 1.

  • the pressurized air element 3 is protected in an additional chamber 9'' .
  • the tempering (warming up or cooling down) of the paint receptacle or -pail is provided by supplying tempered air to the chamber 9' . It is therefore of advantage for the chamber 9' not to be completely sealed, whereby sufficient air also is evacuated from the chamber 9' . Venting may be achieved e.g. by providing a clearance between the cut-out 13 and the paint pail 15 and/or by means of suitable cut-outs (not shown) in the box 9 or in the top portion 11.

  • the apparatus is particularly suitable for use in hazardous, explosive areas, so-called EX-areas. This is because the apparatus only requires work air and no electric current. In processing plants both onshore and offshore, for example production units for production of petroleum products, or on ships, work air is generally easily accessible. Thus, it is normally possible to transport the apparatus according to the invention to an area close to the area at which the surface treatment agent is to be applied.
