Definitions

  • the invention relates to an electrostatic spray device for coating powder, with a powder channel, the downstream end of which has a spray opening for spraying the coating powder, with at least one gas channel which has at least one gas outlet opening which is arranged essentially in the radial center of the powder channel upstream of its spray opening and axially opens towards this spray opening, with at least one electrode around which the gas of the gas channel flows, which is located in the gas outlet opening and whose downstream electrode end terminates approximately at the downstream opening end of the gas outlet opening.
  • Such an electrostatic spray device is known from US Pat. No. 4,289,278.
  • a gas stream flows around the electrode in the powder channel so that no powder particles are to be deposited on it. It does not matter whether the electrode is located in a gas channel or is in the powder flow and the gas flow is supplied with a gas flow that keeps the electrode clear.
  • the electrode is located relatively far upstream of a spray opening for the coating powder, so that the flow situation there has no influence on the effect of the electrode.
  • the electrode is located in the center of a spray opening that widens in the direction of flow.
  • the powder channel has a section with a reduced cross section, to the downstream end of which the spray opening is connected.
  • a carrier extends axially through the powder channel and through the spray opening, which axially carries an electrode at its front end outside the spray opening.
  • a gas channel leading axially through the carrier opens into the spray opening into an annular nozzle formed in the carrier, which nozzle radially outwards against the Wall of the spray opening is directed, which is widened like a funnel in the flow direction.
  • the powder is atomized by the radial radial gas flow coming into contact with the cross-sectionally circular powder channel flow in the spray nozzle.
  • electrostatic spray devices show DE-OS 16 52 421, 23 12 363, 27 20 458 and 33 10 983, CH-PS 609 585.
  • DE-PS 25 39 627 corresponds essentially to the US -PS 3 940 061 and shows an air-flushed electrode in the center of a spray opening of an electrostatic spray device.
  • the object of the invention is to improve the coating quality and the economy of the coating method of such a spray device. Powder losses on the way from the spraying device to the object to be coated should be reduced. Furthermore, the spray device is said to be able to apply a thicker layer of powder to the object to be coated with good coating quality.
  • the powder channel has a funnel-like channel section which narrows approximately from the gas outlet opening to the spray opening and forms a stowage area which compresses the coating powder and into which the gas outlet opening opens, such that the radial center of the spray opening is in place of the smallest diameter of this channel section is located opposite the gas outlet opening.
  • the powder is compressed in the flow congestion area of the powder channel. Since the electrode does not protrude or only slightly protrudes beyond the end of the gas line and is also flushed with gas flowing out of the gas line, no powder particles can adhere to the electrode.
  • the electrical field lines emanating from the electrode run along ideal trajectories of the powder particles from the electrode to the object to be coated without electrical scattering field lines. Avoiding stray field lines, e.g. in the powder channel opposite to the powder flow direction, with the same electrical energy, leads to a stronger charge of the powder particles, which adhere better to the object to be coated.
  • the gas transfers the electrical charge of the electrode into the compacted powder.
  • the spray opening has the shape of a slot.
  • a flat spray jet has the advantage over a round spray jet that it penetrates better into recesses, openings, cavities and niches of the object to be coated, and thereby better coats the inner surfaces thereof. With a circular cross-section the spray jet creates a strong so-called Faraday cage, i.e. a shielding electrical field, which prevents the electrical field lines of the electrode from penetrating into the recesses or recesses. The effect of Faraday's cage is not as disadvantageous with a flat spray as with a round spray.
  • the electrostatic spraying device according to the invention shown in FIG. 1 has a tubular base body 2, which consists of three individual parts 4, 6 and 8 arranged coaxially one inside the other.
  • a mouthpiece 12 is placed on the downstream end section 10 of the base body 2.
  • a powder channel 14 extends axially through the innermost part 8 of the base body 2 and the mouthpiece 12.
  • this has a funnel-shaped channel section 16 which becomes smaller in diameter in the direction of flow and which is provided centrally with a spray opening 18 for spraying the pneumatically conveyed powder. Due to the funnel-shaped narrowing, the channel section 16 forms a flow stagnation area in which the powder builds up and a higher powder concentration arises.
  • the powder channel 14 there is a device 22 in the channel axis 20 which forms a gas channel 24 which extends along the channel axis 20 and in which also houses an electrical electrode 26 along the channel axis 20 at a distance from the channel wall of the gas channel 24.
  • the electrode 26 is connected in a known manner to an electrical high-voltage source (not shown) and serves to electrostatically charge the coating powder.
  • the high-voltage source can be arranged in a known manner in the base body 2 or externally.
  • the gas is injected through an outlet opening 30 of the gas channel 24, which lies axially opposite the spray opening 18, into the funnel-shaped channel section 16, which forms the flow stagnation area.
  • the end 32 of the electrode 26 and the downstream end 34 of the outlet opening 30 lie approximately in a same cross-sectional plane 36, which is at a distance upstream of the narrowest point 38 of the funnel-shaped channel section 16.
  • the cross-sectional plane 36 is only a short distance in the preferred embodiment of approximately 0.5 to 1.5 mm downstream of the upstream beginning 40 of the funnel-shaped channel section 16.
  • the end 32 of the electrode 26 is also in the cross-sectional plane 36 and should, in a modified embodiment , do not protrude more than 1 mm beyond the gas channel 24, since otherwise the desired electrostatic charging of the powder will deteriorate.
  • cross-sectional plane 36 and thus the ends 32 and 34 of a further cross-sectional plane 42, in which the downstream end 44 of the spray opening 18 is located lies in the range between 3 mm and 5 mm.
  • the distance is preferably approximately 4 mm according to FIG. 1, in which the spray device is shown on a 2: 1 scale.
  • An electrical resistor 46 is accommodated in the gas channel 24, which runs axially to the powder channel axis 20, and is located in an electrical line 48 connecting the high-voltage source to the electrode 26.
  • the electrical resistor 46 serves to prevent electrical flashovers from the electrode 26 to other objects. This is better prevented the closer the resistor 46 is arranged to the electrode 26.
  • the funnel-shaped channel section 16 is conical and its inner channel wall 54 narrows at a cone angle a of 120 °.
  • the cone angle can be in the range between 100 ° and 140 °.
  • the outer end face 52 of the mouthpiece 12 runs parallel and thus at the same angle as the inner channel wall 54.
  • the spray opening 18 is in the form of a slot which extends symmetrically over the central axis 20 of the powder channel 14, the slot with both slot ends 57 extending upstream behind the cross-sectional plane 36, preferably up to a distance 56 of approximately 8 mm from the cone tip 58 of the end face 52 of the mouthpiece 12.
  • the distance 56 should be in the range between 5 mm and 10 mm. However, the preferred distance is 8 mm.
  • Upstream of section 60 is an annular channel section 64 of powder channel 14, which has an increasingly larger opening cross section in the direction of flow up to a largest opening cross section at the beginning of the following section 60.
  • the annular section 64 is defined by the cylindrical wall 62 and the the length of this section 64 is formed as a truncated cone-shaped outer surface 66 of the device 22.
  • the powder channel 14 Upstream of the device 22, the powder channel 14 has a hollow cylindrical section 72.
  • the flow velocity of the powder is accelerated when it flows from the section 72 into the section 68, since the device 22 reduces the opening cross section of the powder channel 14.
  • the opening cross section increases again, so that the flow velocity of the powder particles slows down and the powder distribution is made more uniform.
  • the flow is calmed, and then the powder is compressed in the funnel-shaped channel section 16.
  • the gas of the gas channel 24 injects electrical charge particles from the electrode 26 onto the powder particles in the channel section 16.
  • the slot 2 shows the slit-shaped shape of the spray opening 18 from the front.
  • the ratio of the length to the width of the slit 18 must not be too large.
  • the slot preferably has the dimensions shown in FIGS. 1 and 2.
  • the invention achieves a particularly strong improvement in the electrostatic charging of the powder, the economy and the coating quality, in particular in a spray device in which the spray opening is in the form of a slot, with layers of greater thickness on the object to be coated in a single spraying process can be generated. It is particularly important that the electrode does not protrude substantially from the gas channel and that the distance 41 is approximately 4 mm.
