Definitions

  • the invention relates to a device for heating the paint and spray air supplied to a paint spray gun through hoses or the like.
  • hose for the paint and the spray air has a considerable weight, so that the operator of the paint spray gun quickly tires.
  • Another disadvantage is that the arrangement of the heating device and additional hose reduces the mobility of the hoses, so that the handling of the paint spray gun also suffers.
  • the object of the invention is therefore to propose a device of the type mentioned at the outset which ensures the necessary heating of the supplied paint and spray air without impairing the manageability of the paint spray gun.
  • This object is achieved in that a heat exchanger is provided with a heating element and that a heating coil for the paint and for the spray air is arranged in the heat exchanger.
  • the heat exchanger is preferably cylindrical.
  • the heat exchanger is advantageously filled with water.
  • an electrically heatable heating element is provided as the heating element.
  • the heating rod in the heat exchanger is preferably U-shaped.
  • the heating element is advantageously arranged in the middle of the heat exchanger in the longitudinal direction of the heat exchanger.
  • the heating coils for the paint and the spray air are preferably designed as copper tubes.
  • the heating coils are advantageously arranged helically around the heating rod in the heat exchanger.
  • the heating coils are preferably arranged in opposite directions in the heat exchanger in such a way that the paint and the spray air flow through the heating coils in the opposite direction.
  • a temperature sensor with a switch controlled by the temperature sensor, which is effectively connected to the heating element, is advantageously arranged in the heat exchanger.
  • the invention is exemplified in the drawing in longitudinal section.
  • a cylindrical heat exchanger 1 has a U-shaped heating rod 2 running in the middle in the longitudinal direction, which can be heated electrically.
  • the heating element 2 is attached to one end face 3 of the heat exchanger 1.
  • two heating coils 4 and 5 made of copper tubing are arranged in a helical pattern, the inlet and outlet openings of which are arranged on the other end face 6 of the heat exchanger 1.
  • the heating coil 4 has the inlet opening 7 and the outlet opening 8 on the end face 6.
  • the heating coil 5 has the inlet opening 9 on the face side 6, which is opposite the outlet opening (not shown in longitudinal section) for the heating coil on the front side.
  • the medium supplied to the heating coil 4 is first transported in the heat exchanger 1 up to near the front side 3 and then flows through the helical heating coil in the direction of the other end side 6.
  • the medium supplied to the heating coil 5 comes from the inlet opening 9 first moved in the helical section of the heating coil from the end face 6 to the end face 3 and then flows back to the outlet opening, not shown.
  • the heat exchanger 1 has an opening 11 which can be closed by a valve cover 10 and through which the heat exchanger can be filled with water.
  • the valve cover 10 prevents the creation of excess pressure.
  • thermometer 13 for displaying the water temperature is arranged in a further opening 12 of the heat exchanger 1.
  • a temperature sensor 15 is arranged in a third opening 14 of the heat exchanger 1 with a switch, not shown, which is controlled by the temperature sensor and is effectively connected to the heating element 2.
  • the device When using the device according to the invention, the device is connected to an electrical power supply and the heating element 2 is switched on by adjusting the temperature sensor 15, so that the water in the heat exchanger 1 heats up to the set value.
  • the hose lines for paint and for spray air are connected to the heating coils 4 and 5, so that the paint and the spray air are heated by the heated water in the heat exchanger 1 via the heating coils.
