Die Erfindung betrifft einen elektrischen Durchlauferhitzer zur Erhitzung von flüssigen Anstrichmitteln, die mittels Farbspritzpistole aufgetragen werden.The invention relates to an electric water heater for heating liquid paints, which are applied with a paint spray gun.
Es ist bereits bekannt, Farbe zu ihrer Erhitzung einen zylindrischen, elektrisch beheizten, thermostatregulierten Metallkörper durchströmen zu lassen, in dessen Umkreis eine gleichförmige schraubenförmige Rille eingegossen ist, die mittels eines den Metallkörper umschließenden zylindrischen Rohres einen Kanal für die durchströmende Farbe bildet.It is already known to use a cylindrical, electrically heated, thermostatically controlled paint to heat it To let flow through metal body, in its periphery a uniform helical Groove is cast, which by means of a cylindrical tube surrounding the metal body Forms channel for the paint flowing through.
Eine derartige Konstruktion schließt jedoch gewisse Nachteile ein, wenn der Durchströmkanal in seiner ganzen Länge aus einer gleichmäßig geformten schraubenförmigen Rille besteht, die überall dieselbe Querschnittsfläche aufweist. Bei ihrem Eintritt in den Erhitzungskanal bei Zimmertemperatur ist die Farbe dick und zähflüssig. Um den Druckabfall beim Strömen der Farbe durch den Erhitzungskanal zu vermindern und gleichzeitig die Wärmeaufnahme zu erhöhen, darf der Kanal nicht gleichförmig sein, sondern muß an seinem Beginn eine größere und an seinem Ende, wo die Farbe höhere Temperatur hat und infolgedessen dünner ist und leichter fließt, eine kleinere Querschnittsfläche haben. Die größere Querschnittsfläche im Gewinde wird aus Fertigungsgesichtspunkten zweckmäßig dadurch bewirkt, daß der Innendurchmesser des Kanals durchgehend derselbe ist, daß man die Rillentiefe am Beginn größer hält und zum Ende des Kanals hin allmählich abnehmen läßt. Hieraus ergibt sich eine konische Form für den Metallkörper, wodurch sich sowohl für den Metallkörper als auch für den ihn umschließenden Mantelbehälter die Möglichkeit des Kokillen- oder Preßgusses bietet.However, such a construction includes certain disadvantages when the flow channel in its entire length consists of a uniformly shaped helical groove that runs everywhere has the same cross-sectional area. When they enter the heating channel at room temperature the paint is thick and viscous. In order to reduce the pressure drop when the paint flows through the heating channel and at the same time the heat absorption to increase, the channel must not be uniform, but must have one at its beginning larger and at its end where the paint has higher temperature and is consequently thinner and flows more easily, have a smaller cross-sectional area. The larger cross-sectional area in the thread is made From a manufacturing point of view, it is expediently brought about by the fact that the inside diameter of the channel is continuous the same is to keep the groove depth larger at the beginning and gradually towards the end of the channel can decrease. This results in a conical shape for the metal body, which results in the possibility for both the metal body and the jacket container surrounding it of the chill or die casting offers.
Um zu verhüten, daß die Farbe im Farberhitzer bei Unterbrechung des Spritzvorganges überhitzt wird, und damit sie sich innerhalb des für Warmspritzung zweckmäßigen Temperaturbereiches von 50—90° C hält, ist der Farberhitzer mit einem Thermostat ausgestattet. Bei Unterbrechung im Spritzvorgang ist es jedoch wichtig, daß die Farbe, die sich in der Farbleitung (gewöhnlich einem Gummischlauch) befindet, durch den sie vom Farberhitzer zur Spritzpistole vorgeleitet wird, auch während der Unterbrechung im wesentlichen auf konstanter Temperatur bleibt. Um dies zu ermöglichen, wurde die Anordnung getroffen, in den Metallkörper ferner ein beispielsweise U-förmiges Stahlrohr einzugießen, das an zwei Bohrkanälen in dem Stahlflansch festgeschweißt ist, auf die der zweckmäßig aus Aluminium oder Silumin bestehende Metall-Elektrischer Durchlauferhitzer für AnstrichmittelTo prevent the paint in the paint heater from overheating when the spraying process is interrupted and so that it is within the temperature range of 50-90 ° C, the paint heater is equipped with a thermostat. If there is an interruption in In the spraying process, however, it is important that the color that is in the paint pipe (usually a Rubber hose) through which it is fed from the paint heater to the spray gun, even during the interruption remains essentially at a constant temperature. In order to make this possible, the arrangement was made to also cast a U-shaped steel pipe, for example, into the metal body, which is welded to two drill channels in the steel flange, on which the appropriate Metal-electric instantaneous water heater made of aluminum or silumin for paints
