Definitions

  • Flow paint heaters are usually used in paint spraying devices to preheat the paints which are subsequently to be applied with a spraying or spraying device.
  • the heating of the colors leads to an improved material application and is carried out by means of the flow heater, which is interposed between a feed pump and a spraying or spraying device.
  • the invention has for its object to provide a flow heater for a paint spraying device of the type mentioned, which allows a high volume material throughput with a simple structure and inexpensive to manufacture, ensures safe and reproducible heating of the paint and inexpensive to repair when the paint dries or is to be cleaned.
  • the flow heater according to the invention is characterized by a number of considerable advantages. By dividing it into a first and a second component it is possible to separate the heating device from the component provided with the passage channel, so that the latter can be cleaned without the expensive and unprotected heating device being affected. For example, it is possible to place the first component provided with the passage channel separately from the main component in a cleaning bath or to remove adhering material residues by ultrasound exposure.
  • a further advantage of the flow heater according to the invention is given in that the first component can be replaced in a simple manner, for example in the case of a color change or in an application in which the volume throughput of the color is to be changed.
  • the second main component provided with the heating device is only required once and can be used for various first components. This measure results in a considerable cost reduction since, in comparison to the known flow heater for the most varied of applications and / or for maintenance purposes, only a few first components are required.
  • Another advantage of the flow heater according to the invention is given by the fact that the first component can be constructed simply and robustly, while more sensitive parts, such as the ex-protected control device and the heating elements, are provided in the main component which is required only once, which is particularly important in the cleaning phase of the flow channel is separated from the first component and is therefore not subjected to any loads.
  • the first component has a conical recess into which a conical extension of the second component can be inserted.
  • This configuration ensures particularly good heat transfer from the second component to the first component, since, owing to the taper, the two components have a large, gap-free contact area.
  • the conical design also ensures a secure fit, which proves to be particularly advantageous when the flow heater is used by untrained personnel under harsh operating conditions.
  • a further advantageous embodiment of the flow heater according to the invention can also be given by the fact that a plurality of passage channels arranged parallel to one another are provided, which can additionally be connected to a common material inlet and a material outlet.
  • a plurality of passage channels arranged parallel to one another are provided, which can additionally be connected to a common material inlet and a material outlet.
  • Figure 1 is a side view, partly in section, of an embodiment of the flow heater of the paint sprayer according to the invention.
  • the flow heater comprises a first component 2, which is provided with helical passage channels 1, and a second main component 3, which comprises a heating device 4.
  • the heating device 4 of the second component 3 is designed in the form of a plurality of heating rods which are arranged in a conical extension 6.
  • the heating elements are designed in the usual way and are connected to a control device (not shown in detail) and an overheating protection, which in turn is connected to a power connection 10.
  • the second component 3 further comprises a control switch 11, only shown schematically.
  • the first component 2 is essentially cup-shaped and has a conical recess 5 which is designed to match the conical extension 6 of the second main component 3. Due to the cup-like design, the first component 2 has a wall 7, in which helical passage channels 1 are formed.
  • the passage channel 1 is connected to a material flow 8 or a material flow 9. When the passages 1 are connected in parallel, a flow is also possible if one of the passages 1 should be blocked.
  • screws 12 are provided which extend through a recess in the bottom region of the first component 2 and can be screwed into a threaded recess of the conical extension 6 are.
  • a separation of the first and the second component can be facilitated in that the screws are screwed into threaded bores 13 in the bottom of the first component 2, which are only shown in broken lines in FIG. 1 and are provided with the reference number 14.
  • the screws 12 can be screwed into the threaded bore 13 after they have been removed and can be used to loosen the two components.
  • the first component 2 can be cylindrical in terms of its outer dimensions, the passage channels 1 can be in the form of ring channels, but it is also possible to design the first component 2 polygonally, for example square, in terms of its outer dimensions.
  • the flow heater according to the invention is thus characterized in that particularly good heat transfer values are ensured by the intimate connection between the removable part and the heating device, so that the paint pressed under high pressure and at high speed by the flow heater can be heated or preheated in a controllable manner .
  • This controlled heating or preheating is not possible in the devices known from the prior art or is made considerably more difficult by the construction of the devices.
  • the intimate connection between the detachable part and the heating device creates conditions in the assembled state, as is the case with a one-piece device, but at the same time, due to the detachable design, allows separation for cleaning, replacement or the like.
  • first and second component it is possible to vary the dimensioning of the first and second component in a wide range, for example a different one To provide number of passages or to design the passages with different cross-sectional ratios.

Abstract

Un dispositif de chauffage d'un courant agencé entre un dispositif d'alimentation et un dispositif pulvérisateur présente au moins un canal de passage dans lequel les matériaux, notamment des colorants, sont chauffés au moyen d'un corps chauffant. Ce dispositif de chauffage doit présenter une structure simple, être économique et facile à nettoyer. Le canal de passage (1) est ménagé dans un premier module (2) susceptible d'être attaché à un deuxième module principal (3) pourvu du corps chauffant (4). On peut changer aisément et rapidement le premier module pourvu du canal de passage, qui présente une structure simple et robuste. Par conséquent, on peut utiliser ce dispositif de chauffage de courant pour traiter des matériaux, notamment des colorants.
