    I
    This invention relates to an electrostatic coating technique on the inner surface of light source flasks.
    The applied coating can provide, for example, a scattered light, a modified spectrum of the emitted light or, in the case of a gas discharge tube, transform the light lying in the ultraviolet region into a light beam lying in the visible light region.
    In the electrostatic coating method, a pulverized inorganic substance is used to form a layer of the inner surface of the flask. Dust particles are produced from dust smoke that is electrostatically charged, then blown into the flask. A flask made of glass is electrically connected to one electrode, the other electrode is dust dm4. Preheated in the burner flame, the bulb becomes electrically conductive. The formation of a closed electric circuit occurs during the deposition of an electrically charged, pseudated substance on the inner surface of the flask.
    A device for electrostatic coating of light source flasks is known, comprising a fixed table, an actuator mounted thereon, a mechanical control unit, a gas burner electrode for heating the flasks and firing the applied coating, a dust generator, an electrostatic gun with a metal tube electrode, communicating with a pipe pipe drainage system, a suction system connected to a spray gun to collect a dust-like substance not used in the coating, and Tajftfce about blown open when purging the spray gun, high voltage power supply unit. In the device, the spray gun is directly connected via a pipeline to the expansion chamber of the dust generator, and the pipeline is equipped with an ij valve.
    However, the use of a relatively long, mobile -pipeline in the known device leads to the agglomeration of a pulverized substance and its deposition on the walls of the pipeline 288231
    water and valve surfaces, which adversely affects the quality of the applied coating. In addition, in the known device, an unused pulverized substance is collected first in the drum tank, and then delivered to the piston generator. Using an intermediate tank complicates the design 10 of the device and generally negatively affects its efficiency.
    The purpose of the invention is to increase the productivity of the device and ensure a uniform coating thickness. 15 The goal is achieved by the fact that the device for electrostatic coating on flasks

    Fig. 1 shows a device, a plan} in Fig. 2 is a basic diagram of the operation of the device; on FIG. 5, dust generator; cut in FIG. 4; spray gun, section; on fig.Z - block suction system, section. The device contains a stationary table 1, an actuator mounted on it (not shown), a pivot stop 2, a mechanical control unit including a distribution disk 3 and gas torch-electrode mechanisms 5 with heat pumps 6 for heating flasks, an alternator 8, an electrostatic gun-sprayer 9., suction system 10, power supply unit 11 high voltage. Dust generator 8 consists of a cat with a nus-shaped tank 12 s /. the cap 13 and the bottom 14. On the cover 13 there are mounted a rotating rotor, a guide cylinder 16, pipe 17, communicating with the suction system 10, and pipe 18 connected with the compressed air line. Above bottom 14, a porous partition 19 is mounted, in the middle of which a nozzle 20 is installed. A cavity formed between the bottom and a porous partition, to the nozzle 20 communicate through rotameters 21 to a compressed air line. Pyiegenerator 8 is equipped with a valve 22, together with a gun 9., i:. The electrostatic spray gun 9 consists of radially coupled spray heads 23 with a metal pipe 24, equipped with an ionization electrode 25 and connected to the feed pipe 26 through a expansion chamber 27 equipped with an inlet pipe 28 and installed in the plastic part housing 2.9 and communicating through the pipe, approx 28 with the compressed air line 30. The pipe 26 is connected to a radial cyclone 31, which in turn communicates through pipe 32 to a dust generator 8 and through rubber clutches 33 and pipe 34 to a dust collecting system 10. At the top of the tube-electrode 24 is covered by a plastic pipe 35 communicating with the installed above the core 29, a suction chamber 36 and a spray head 23. The suction chamber 36 is provided with a damper 37. The spray gun 9 is connected through wires 38 to a high-voltage power supply unit 11. 234 The suction system 10 includes an electrostatic cyclone dust removal unit 39, made of acid-resistant steel, grounded and used to trap the dust-air mixture. Cyclone 39 is connected via fan 40 and pipe 41 to the suction chamber 36 of the spray gun 9. At the entrance to the dust cyclone 39, an ionization electrode 42 is installed, which is connected to the negative electrode of a high voltage source. The dust cyclone 39 is provided with a powder agitator 43 and a conical powder collector 44 in which an ejector 45 is mounted, connected through a rubber stopper 46 to the dust generator tube 17 8. The flasks are transported to and from the device using the inlet 47 and 48 output conveyor belts . The device works as follows. The conical part of the tank 12 of the dust generator 8 is filled to 2/3 of its volume with a pulverized substance. Under the porous partition 19 and S the nozzle 20 is supplied with compressed air and the ascending air flow loosens the pulverized substance, which is then further scattered with the help of the nozzle 20. The diffuse dust material moves upwards and hits the rotor 15 that rotates with a large number of revolutions, additionally grinding the fluid substance. On the other hand, the rotor creates a flow in the opposite direction to the upstream flow from the porous partition 19 and the nozzle 20 and causes the pulverized substance to flow between the walls of the guide cylinder 16 and the reservoir 12. This flow returns the large aggregation back to the conical part of the reservoir 12, and dusty substance, free from agglomerations of pulverized smoke, again passes through rotor 15 and, due to this, is crushed again, if during this time period there is agloration. - Both the rotating rotor 15 and the guide cylinder 16 are made of metal and, together with Krishka 13, are azelen, therefore, they are withdrawn during the sprays by air, which also reduces the likelihood of agglomeration. The dust smoke prepared in the generators 8 through the open pneumatic valve 22 through the conduit 32 is introduced into the radial cyclone 31 of the spray gun 9. The rubber stopper 33 is in the closed state. In the cyclone 31 the stuck dust particles formed in the conduit 32 are separated and dust the smoke through the pipe 26 enters the metal pipe 24. The metal pipe 24 is equipped with an ionization electrode 25 and is electrically connected to the high voltage unit 11, therefore the pierced smoke through the pipe 24 is electrically electrically It is pressed and deposited on the wall of the lamp bulb 7, which has become electrically conductive, due to heating by means of burners 5. In this case, the grounded electrode is a gas burner 5, which gives a flame, fanningly covering the lamp flask 7. Unbound dust during the application flows through a plastic tube 35 into the suction chamber 36, from which it is guided to an electrostatic cyclone 39. During application of the coating, the spray gun 9 is in the upper position (position d, Fig. 4). At the end of the coating cycle, the pneumatic valve 22 of the generator generator 8 closes. The spray gun 9 goes down to the position b. The flap 37 closes the suction chamber 36 from above and then the turntable 2 moves in steps. In the lower position of the spray gun 9, the pneumatically controlled rubber shutter 33 is opened and using a valve (not shown) through the pipe 18 and the line 30 into the nozzle 28 blows air to clean the metal pipe 24. The cleaning air enters the pipe 32 connecting dust generator 8 with a radial dust separation cyclone 31, and 236 cleans it from deposited on the walls of the dust-like substance. Under the influence of compressed air, which is introduced through the pipe 28 and the pipe 26, the dust-like material attached to the walls is removed from the outlet pipe of the radial dust separator of the cyclone 31. This dust-like substance passes through the rubber stopper 33 and the pipe 32 enters the thermal trap system 10 where it is fed by a fan 40 through conduit 41 to a dust separating cyclone 39. The ionization electrode 42 connected to the negative pole of the high voltage source discharges particles of a fluid that They are deposited on the walls of a grounded cyclone 39. With the help of a shaker 43, the fluid in the form 44 falls into the collector 44, from which the ejection of the cyclone 39 is cleaned with the help of an ejector 45 with the rubber gate 46 open. filters that are provided) t double filtering. At the end of the cleaning, the rubber shutter 33 is closed, the valve 22 and valve 37 are opened, the spray gun is raised and the cycle is repeated. Thus, the proposed device allows electrostatic coating of the flasks of light sources, ensuring high process efficiency and a uniform layer thickness, moreover. the pulverized substance is not agglomerated and cleaning can be carried out without damage to the environment due to the fact that the pulverized substance that is not bound during the electrostatic coating of the flasks and the pulverized material released during cleaning is completely trapped and transferred to the dust generator, i.e. the process of applying the plowing is carried out without loss, it is important both economically and at work hygiene and environmental protection.
