As shown in Figures 1 and 2: multi-functional anti-clogging high-concentration coal-water slurry spray gun comprises rifle body, anti-interior stream device and three parts of oil spout preheating device; The rifle body is made up of cover cap (1), nozzle (2), nozzle block (3), pipe box (4), cover for seat (5), overcoat (6) and block (7), and pressure-air air inlet pipe (8) and cooling jacket (2 8) are arranged on the pipe box, and water-coal-slurry input pipe (9) is arranged on the cover for seat (5); The stream device is made up of interior nozzle (10), centre pipe (11), big diaphragm (12), big spring seat (13) and big spring (14) in anti-, the front portion of centre pipe is installed in the nozzle block of rifle body by big fixed mount (15), the big spring seat is installed on the big diaphragm by nut (16) and pad (17), and the outer of big diaphragm is fixed between cover for seat and the overcoat; The oil spout preheating device is made up of thimble (18), thimble seat (19), submissile spring abutment (20), little spring (21), Small diaphragm-piece (22) and high-pressure pipeline seat (23), high-pressure pipeline seat (23) is made as one with the big spring seat (13) of anti-interior stream device, high-pressure pipeline (24) is arranged on it, the front portion of thimble is installed in the centre pipe (11) of anti-interior stream device by little fixed mount (25), thimble seat (19) is installed on the Small diaphragm-piece (22) by nut (26) and pad (27), and the outer of Small diaphragm-piece is fixed between high-pressure pipeline seat and the submissile spring abutment.
During spray gun work, light oil (also can be combustion gas) enters in the big spring seat (13) from high-pressure pipeline (24), be installed in Small diaphragm-piece (22) compressive deformation on the thimble seat (19), the elastic force that the drive thimble overcomes little spring (21) moves backward, open interior nozzle (10) spout, light oil is in centre pipe (11) enters interior nozzle (10), enter in the nozzle (2) by the coal slurry inlet hole (32) of interior nozzle (10) on nozzle (2) then, light oil nozzle (2) half in mix in the chamber (33) and enter from pressure-air air inlet pipe (8), enter the pressure-air mixing of the high pressure pore (34) on the nozzle (2) again along pipe box (4) inwall after, by nozzle (2) ejection, just can light a fire.After the igniting, when special furnace temperature rises to uniform temperature, water-coal-slurry is entered in the cover for seat (5) by water-coal-slurry input pipe (9), be installed in big diaphragm (12) pressurized between cover for seat and the overcoat, the elastic force that drive big spring seat (13) and centre pipe (11) overcome big spring (14) moves backward, make between interior nozzle (10) and the nozzle (2) and form passage, water-coal-slurry enters half interior mixing in the chamber (33) of nozzle (2) through above-mentioned passage along nozzle block (3) inwall.Meanwhile, pressure-air is entered in the pipe box (4) by pressure-air air inlet pipe (8), rotate into half interior mixing in the chamber (33) along pipe box (4) inwall through 4 the eccentric high pressure pores (34) on the nozzle (2), fully mix the back ejection with half interior water-coal-slurry of mixing in the chamber (33) and burn, finish igniting.After igniting is finished, the light oil of high-pressure pipeline (24) is switched to pressure-air, then pressure-air arrives along the oil circuit track and mixes chamber (33) in half and participate in mixing, ejection burning, supplies with boiler heat energy.When needing to cease fire; stop the coal slurry of spraying water earlier; then big diaphragm (12) release; big spring (14) drives the big spring seat under the elastic force effect and centre pipe resets; interior nozzle (10) is blocked nozzle (2) stock inlet passage; surplus slurry in the nozzle block (3) can not flowed in the nozzle (2), allow the pressure-air from the high pressure pore (34) on interior nozzle (10) and the nozzle (2) rinse the interior remaining coal slurry of nozzle (2) momently, stop air feed then.At this moment, thimble (18) is pushed ahead thimble by means of little spring (21) effect and is clogged interior nozzle (10) spout, and Small diaphragm-piece (22) resets.So the utility model is exactly when quitting work, and also needn't withdraw from being soaked in water.For improving the working environment of nozzle, we are provided with cooling jacket (28) outside pipe box, cooling water is entered in the cooling jacket by cooling water inlet pipe (29), through water jacket partition (31) one side inflow water jacket ante-chambers, arriving cooling water outlet pipe (30) through the water jacket partition opposite side again flows out, so continuous supply water quench nozzle guarantees that spray gun normally uses.
Switch in the process of pressure-air at light oil high-pressure pipeline, behind fuel cut-off, be installed in Small diaphragm-piece (22) displacement forward under the elastic force effect of little spring (21) on the thimble seat (19), drive thimble (18) and clog interior nozzle (10) spout, prevent that the water-coal-slurry between interior nozzle (10) and the nozzle (2) from entering in the interior nozzle (10).
The utility model is not when using oil spout preheating device part, and nozzle can be solid plug in it.
