Description

The invention relates to equipment for painting and painting to be used in any industry.

The installation of a jet spout is known, socializing the drenching chamber with a bathtub and steam taps installed between the inlet and outlet vestibules with air curtains, the solvent vapor and paint and solvent tanks interconnected with fl.

The disadvantage of the installation is that the paint and solvent bins, connected by pipelines with shut-off valves to the pouring chamber, are placed on the same

level (on the floor, floor), as the whole installation of the jet spraying, and for this, significant production areas are required. Tanks can also be placed in the primus, due to which the production area is reduced. But both in the first and especially in the second case, the delivery system of the dfaska is significantly complicated, which should include a solvent washing system.

In addition, the length of the paint ducts is significantly extended, which causes the paint to heat up and coagulate. Finally, this topic of paint supply has a large number of valves.

In order to flush the camera of a floucaster and paint pipes in a known stream pouring unit with a solvent, it is necessary to stop working paint supply pumps, blow out the system with compressed air, use the taps to shut off the paint pipe connecting the pouring chamber pan to the paint tank, open the paint pipe crane, connect Pick up the chamber of the tank with the solvent tank and turn on the solvent supply pump.

The aim of the invention is to simplify the supply of paint to the chamber and the whole installation.

The goal is achieved by the fact that the tanks are placed one above the other, with the lower tank installed above the level of the liquid in the bath of the overflow bath.

FIG. 1 shows schematically the proposed spray jetting installation; in fig. Figure 2 is a schematic diagram of the Krai feed system. The jet pouring unit consists of the inlet 1 and outlet 2 of the vestibules with air curtains 3, the sweeper circuit 4 of the jet pouring loop, the pouring chamber 5 of the bath 6, the solvent vapor recirculation system 7, the steam tunnel 8, the overhead conveyor 10 through which the product 11 is fed and paint supply systems 12. The paint supply system includes the upper 13 and lower 14 tanks, pumps 15, viscometer 16, filters, heat exchanger 18, jetting circuits 19 with nozzles 2O and adjusting valve 21 valve 22; DP compressed air supply, collector 23 For flushing waste flooding 24 , overflow ink pipe 25 in case of overflow of bad 13 and 14, edge of duct 26 for ink discharge from paint supply system when it is being washed, valve 27 for shutting off ink conduit 26, valve 28 for washing 1k of drain tray 24. The installation also contains a test cock 29, waste kraskoprovod 3; p from to isosimeter, taps 31 for supplying paint to filters 17, taps 32 for supplying paint to heat shaler 18, waste paint lines DZF from filters 17, taps 34 on paint lines 33, pressure paint line 35 with crane 36 connected to a pump 15, valve 37 for filling the top tank 13 , valve 38 for filling the lower tank 14, cr & n 39 for draining the dyes into the bath 6, automatic feed valve 40 to dissolve the bath 6, the stop valve 41 (Fig. 2) and a common shut-off valve 42 on the suction head paint. Installing a jet spraying works as follows. The rocking mechanism 4 of the jet pouring circuit is turned on, the fan of the system 7 recirculates solvent vapors, the fans of the air curtains 3, one of the pumps 15, and the paint is supplied to the jet nozzles 2 of the contour 19 of the jet pouring in the following paint lines: from the pump 15 via the Hanoj paint line / 35 to the open valve 36, then through the open valve 31, the filter 17, the heat exchanger 18 and the adjusting valve 21 to the contour 19 of the jet spraying and through the nozzles 20 to paint the iyV surface. Thus occur; products; If it is necessary to free the bath 6 from the paint, then through the pressurized paint line 35 through the open valve 37, the paint is pumped into (Upper tank 13. When it is necessary to blow it out with compressed air, open the Hungarian 22, displace the paint Through the open valve 36, pressure paint pipe 35, through working pump 15 (valve 42 is closed) and open valve 27 through waste paint pipe 26 to upper tank 13 (valve 37 is closed). If necessary, drain the solvent from the lower tank 14 into the bath откры open valve 39, and through the overflow paint pipe the solvent flows into the bath. In the case of promy The kraoki supply system includes a working pump 15 and, injecting solvent into the jetting circuit 19, processing the chamber by pouring 5. The valve 28 is opened and the waste tray 24 is rinsed. The paint is drained from the upper tank 13 (Fig. 2) into the lower J valve 38 (valve 39 is closed); The solvent is pumped into the upper tank 13 by means of a working pump 15 for head pressure, through the spray line 35 through valve 37 and the tank 13 is processed. The paint is drained into bath 6 (Fig. l) jetting plants and the solvent in the lower tank 14 through the open valve 38 and the tank is treated with a solvent. The design of the proposed installation / allows you to reduce the time spent preparing it to work, simplify flushing, refuse to use one of the pumping units, reduce the number of shut-off and control valves. Formula of the Invention and Installation, jet-watering, containing a chamber with a bath and steam tunnel installed between the inlet and outlet vestibules with air curtains, solvent vapor recirculation system, paint and solvent tanks interconnected with pipe mounts, m and h but. “In order to simplify the flow of paint into the pourer chamber and flush the entire installation, tanks are placed one above the other, with the lower one installed above the level of the liquid in the poured chamber bath.
