    The invention relates to a powder sprayer with electrostatic charging capacity and by means of which in a simple and effective manner by way of example a coloring powder can be electrostatically charged, so that it will be completely charged all over the entire surface of the particles. The powder sprayer (1) comprises a number of curved charging ducts (6, 6') of long extension made of electrically non-conducting material which ducts are coated with an electrically conducting layer (7) along the main portion of their extension, said coated layer (7) being connected to a conductor (8, 10) intended by way of example to be connected with the ground, whereby a charging of the powder material takes place during its movement through said charging ducts (6, 6') after contact with the inner walls of the ducts (6, 6'), when the sprayer is in use.

    one :
    This invention relates to a spray coating technique for triboelectrically charged powdered particles.
    kJ -I
    Known powder spray,
    containing a cylindrical body with space; The triboelectric charging unit of the powder in it, made of a dielectric material, the butt plate and nozzle lj
    The disadvantage of this sprayer is the inefficient charging of powder particles in a triboelectric charging unit having a small length and contact area with powder particles c.
    The aim of the invention is to increase the efficiency of powder charging.
    The goal is achieved by the fact that in a nopoujkobom atomizer containing a cylindrical body with a triboelectric powder charging unit made of a dielectric material, the butt plate and a nozzle are located there, the charging unit is made of a plurality of elongated t-arms covered on the outside with an electrically conductive layer the main honor of its length and each of the tubes has a wire connected to its electrically conductive layer
    Moreover, the wires from all the tubes are combined into a common ground wire.
    In addition, the ends of the tubes are fixed in the cores, in which they are placed around the periphery of the ring with an interval between them.
    In this case, the core on the side of the back plate is provided with a distribution cone located in the central part of the core.
    The tubes of the charging unit are spirally bent or the tubes are bent along an arbitrary curve.
    Fig 1 shows a powder sprayer, a general view; in fig. 2 rear end of the sprayer, partial cut; in figo 3 - a tube with a wire; in fig. k - the front end of the sprayer, a partial section; in fig. 5 and 6, respectively, the front and rear ends of the sprayer, a partial section made according to one of the embodiments of the invention.
    The powder sprayer shown in FIG. 1- consists of a connecting element 1 to which a powder supply hose is attached to a silo (not shown a cylindrical body 2 in which the charging unit is located, and a sprayer nozzle 3. Cylindrical body 2 consists of a pipe A made of plastic. In the pipe j there are tubes 5 of a charging unit, having an elongated shape and spirally twisted among themselves. The tubes 5 are made of plastic or other non-conductive material and are covered outside with a conductor; ny element 1
    includes the butt plate 7, and each of the tubes, on the end facing the boom. Nick 7 has a wire B ;, connection. with conductive layer 6 by means of a paired connection 9 All wires 8 are connected to one common wire 10, which leads out of the pipe through a hole made in it and can be grounded or connected to a power source. The ends of the tubes 5 are fixed in the cores 11 and 12, the Rear core H and the front core 12 have a plurality of through holes 13 on their periphery, which are located at a certain distance from one another and are intended for insertion of tubes 5 into the center of the rear core 11. distribution cone T, which with its point is directed in the direction opposite to the direction of movement of the powder, and this cone distributes the incoming powder. The rear end of the pipe k is connected to the sleeve 15 provided with a fitting 16 for connecting the sprayer to the feed hose of the hopper powder. The nozzle 3 is fixed to the opposite end of the pipe 5 The nozzle 3 consists of a spray head 17, a connecting tube 18 and a throttle sleeve 19 Throttle sleeve 19 The rear end is connected to the pipe k with the help of the coupling 20 and has a tapered channel 21 that is conically reduced in the direction of powder movement. The connecting pipe 18 is inserted into the choke sleeve 19 at the rear end and is held in the last dny end of the connecting tube 18 is screwed a ring 22, which in turn holds the head 17 O-ring 22 extends through the axial passage 23, which is connected with a hose 2 for supplying gas such as air. The spray head 17 contains a sleeve 25, the end wall 26 of which is made with a central hole 27 having a chamfer 28 on the outside and a step 29 on the inside. On the ledge 29 mounted front horse diffuser 30, having the shape of a pipe and made, for example, by sintering of porous air-permeable material. The rear end of the diffuser is screwed into the ring 22 and rests on the front end of the connecting tube 18. The head 17 with the diffuser 30 forms a chamber 31, which is separated from the through channel 32 of the nozzle 3 by a porous material. The powder spray gun shown in figs 5 and 6 is similar in design to that described and differs from it in that it is equipped with charging tubes 5 not spirally, but irregularly bent, and each tube 5 is located in many areas. The spray gun works as follows An air paint is supplied through the hose through the fitting 16 to the butt plate 7 by means of air flow and is distributed evenly through the holes 13 of the core 11 with the help of a distribution cone 1, and then through the tubes 5 which are either grounded or connected to The high voltage supply point is connected with wires 8 and 10. Due to the spiral shape of the tubes 5, the powder in them whirls as it moves, with the result that all sides of the particles come into contact with the walls of the tubes. Upon exiting the tubes 5, the powder acquires a significant charge. After exiting the tubes 5, the powder is choked by means of the choke sleeve 19 and along the connecting sleeve. the tube 18 is guided through the through channel 32 to the spray head 17 where it is mixed with air entering through the hose 24 and the diffuser 30, is compressed and then sprayed out of the opening 27 of the spray head. At the same time, the powder is dispersed in the form of a mist and, due to the electrostatic charge, moves to the product and settles on the hard-to-reach areas of the product, which are not available. The powder dispenser is reliable in operation and provides affective charging of the bottle. five
