    Electrostatic spraying apparatus comprises a rotary spraying head and a multiple electrode arrangement which includes two high voltage electrodes one of which has an uninsulated portion, and a grounded electrode. A paint flow space is defined between the uninsulated portion and the grounded electrode as well as the remainder of the one high voltage electrode and the grounded electrode. The second high voltage electrode is spaced outwardly from the grounded electrode and has an insulating layer both on its outer side and on its side facing the grounded electrode.

    The invention relates to devices for dyeing products by electrostatic spraying. An electrostatic spraying device containing a spraying head, a high-voltage electrode and a grounded electrode installed in relation to the high-voltage one through an insulation layer with a gap for supplying paint 1 is known. However, in this device, it is possible that the material already sprayed on the elements of the device leads to significant losses dye and the need to clean the device. The purpose of the invention is to prevent paint from settling on the device. For this, an electrostatic spraying device containing a spray head, a high voltage electrode and a grounded electrode, installed in relation to the high voltage electrode through an insulation layer with a gap for supplying paint, is provided with an additional high voltage electrode installed through an insulation layer behind the grounded electrode on the opposite side paint clearance. Both high-voltage electrodes on the side opposite to the ink supply gap are coated with insulating material. The spray head can be made in the form of disks made of insulating material mounted on a vertically mounted drive shaft, in the upper one of which there is a high-voltage electrode, and in the lower one the grounded and additional electrodes, with the electrodes made in the form of disks. The spray head can be made in the form of two bowls of insulating material mounted concentrically on the drive shaft, in the inner one of which there is a high-voltage electrode, and in the outer one - a grounded and additional high-voltage electrodes, with the electrodes made in the form of cylinders. The outer bowl is provided with a blade crown of insulating material, and the additional high-voltage electrode is made in the form of a cylinder with a blade crown. The spray head can be made concentrically mounted with a gap for supplying a lot of air from cylinders of insulating material, along the axis of which a high-voltage electrolyte is installed, a cylindrical grounded electrode is placed in the inner cylinder, and a high-voltage electrode made in an external cylindrical tube.
    On FR5g. 1 shows an electrostatic spray device with a disk spray head, an axial section; in fig. I - a device with a cup spray head, axial incision; Figures 3–4 are the same, embodiments; Fig 5, section A-A in FIG. 6, an embodiment of the device with a zoomed nozzle.
    The electrostatic spraying device contains a spraying head made, for example, of the form of disks 1 and 2 mounted on a vertically mounted drive unit of the r.axiy 3 and made of isolate and / or ionic material with a high-voltage electrode 4 and a grounded electric electrode. 5, established in relation to FASTLY. 4 through a layer of insulation with a gap b for supplying paint.
    The device is equipped with an additional high voltage voltage electrode 7, installed through a layer of isol. for the grounded electrode 5, with the SST: 1On opposite to the gap 6 for the supply of paint Electra-rays 4, 5 and 7 In the form of discs High-voltage electrode 4 is placed in the upper disk 1, and the closed-end (5) and high-voltage (7) electrodes - in
    Central part of the lightweight disk
    type 4 is in direct contact with the gap 6, and the peripheral part of the electrode 4 is insulated from the gap b. High-voltage electrode 4 is connected to the shaft 3 of the device by means of a metal tube 8. Metric line rod 9f is installed along the axis of the tube 8 and is electrically connected to the ground electrode and through the sliding contact, the 5th. leg., the tube 8 and the rod 9 are insulated between themselves and the outside by the insulating layers 10, the tube 8 through the slide. A common contact is connected to a voltage source 11. The high voltage electrode 4 and the additional high voltage electrode 7 on the side of the opposite gap 6 for supplying a crush screen are covered with insulating material ..
    The device is equipped with a 12 ”drive. An additional high-voltage electrode 7 is electrically connected to the high-voltage electrode 4 by means of a contact spring 13 from the recess installed with a gap in the hole 14, an electrode 5 made in the gap.
    A container is provided for supplying paint to the spray head.
    15, pump 16, pipe 17 and reservoir 18 with a hole 19.
    The device works as follows.
    The paint from the tank 15 is pumped through the pipe 17 into the reservoir 18p from where, through the opening 19, it blasts into the gap b between the disks 1 and 2, contacts the high voltage electrode 4 and charges, the charge of the paint under the actual electrostatic field is. Although the TYUTO moving towards 1.Arifgia. K-paint is no longer in contact with the high-voltage electrode 4, under the action of the grounded electrode 5 the greater density of the arc is preserved. At the exit from the spray edge of the spray head, under the effect of charge and centrifugal force, the paint is sprayed and transferred to a grounded product.
    Up to about t and tel and s and high about t s and s and electrode 7 has on a-charged particles of paint Hc glavlivuyu impact prevents it from a spreading device.
    According to the exemplary embodiment shown in Fig. 2, spraying:; - the shaker is made in the form of concentric; mounted on the drive shaft 21 with the drive 22 two 4aiii 23 and 24 made of insulating material, in the inner of which high-grade is placed. light electrode 25, and an external ground electrode / electrode 26 and an additional high-voltage electrode 27, in the form of cylinders and covered with insulating material on the side opposite to the gap. High-voltage electrodes 25 and 27 of the Connection are electrically. The high voltage electrode 25 is electrically connected with voltage 11. Electrode 26 zaze.mlen through spring 28,
    FIG. 3 shows an embodiment of the device shown in FIG. .2, - 3 which is the outer vat
    29filled with a disc-shaped rib
    30 of an insulating material, and an additional high-voltage electrode is made in the ID of a cylinder 31 with a spike-shaped edge 32.
