Abstract
The utility model discloses a ring-shaped atomization spray gun for slurries, which comprises a sleeve. An air duct is arranged in the sleeve, a slurry pipe is mounted in the air duct, and a lance core is arranged on the front end of the slurry pipe. A locking block is disposed on the front end of the lance core, and a connector is arranged on the front end of the locking block. The connector is connected with the sleeve and the air duct, a lance head is arranged on the front end of the sleeve, and a bowl-shaped ring muzzle is opened on the middle portion of the lance head, and a bolt which is fixed on the connector is arranged in the muzzle. The utility model changes the current multi-hole output into a ring-shaped output, has excellent atomization effect, and is not easy to lock the gun. The utility model can keep the proportioning of slurries and wind through regulating the gap between the ring-shaped muzzle and the bolt to regulate the quantity of gunite work, which can not affect the combustion order.
Description
Technical field
The utility model relates to a kind of water-coal-slurry spray gun.
Background technology
Spray gun is a vitals in the cool water mixture burning equipment.The water-coal-slurry spray gun that uses is to offer a plurality of through holes in the end of rifle head at present, adopt the porous atomizing, yet there are some defectives in this kind mode: though the too little atomizing effect in aperture is good, and easily stifled rifle, the aperture is atomizing effect difference influence burning too greatly.Load Regulation in the rifle is to control the whitewashing amount to reach the purpose of Load Regulation by the revolution of regulating slurry supply pump in addition, and wind slurry proportioning does not have fixed proportion, influences atomizing effect.
Summary of the invention
The purpose of this utility model provides a kind of water-coal-slurry annular atomizing lance, and it is good and be difficult for advantage such as stifled rifle that it has an atomizing effect.
The technical scheme in the invention for solving the above technical problem is: water-coal-slurry annular atomizing lance, comprise sleeve, be provided with air hose in the sleeve, be provided with the water-coal-slurry pipe in the air hose, the front end of water-coal-slurry pipe is provided with the rifle core, the front end of rifle core is provided with sprue, the front end of sprue is provided with connector, connector branch sleeve and air hose, and the front end of described sleeve is provided with the rifle head, the middle part of rifle head offers bowl-shape annular muzzle, is provided with the bolt that is fixed on the connector in the muzzle.
The end of above-mentioned bolt for annular muzzle adapt bowl-shape.
Above-mentioned sleeve and connector are by being threaded.
The end of above-mentioned sleeve and air hose are by being threaded.
Be provided with air flue between above-mentioned rifle core and the air hose, on the rifle core, also be provided with the passage that communicates with air hose.
Be provided with the air flue that supplied gas enters between above-mentioned sprue and the rifle core.
Offer through hole on the above-mentioned connector.
The beneficial effects of the utility model are: because muzzle is become annular output from porous output, atomizing effect is good, be difficult for stifled rifle simultaneously, simultaneously when regulating whitewashing amount big or small, only need turnbarrel, the space change between muzzle and the bolt is got final product, and this kind regulative mode, the proportioning of water-coal-slurry and wind is immobilized always, so can not influence the combustion conditions of burner hearth.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail, as shown in Figure 1, water-coal-slurry annular atomizing lance, comprise sleeve 1, the front end of sleeve 1 is provided with rifle head 11, the middle part of rifle head 11 offers bowl-shape annular muzzle 12, be provided with air hose 2 in the sleeve 1, sleeve 1 is threaded with air hose 2 by the connector 3 that is arranged on air hose 2 front ends, the tail end of sleeve 1 also is connected with air hose 2 by screw thread, be provided with water-coal-slurry pipe 4 in the air hose 2, the front end of water-coal-slurry pipe 4 is provided with the rifle core 5 of approximate " H " shape, rifle core 5 by two openings towards on the contrary " U " shape groove 51,52 and middle connector 53 constitute, offer through hole 54 on the connector 53, insert in " U " shape groove 51 end of water-coal-slurry pipe 4, between the outward flange of water-coal-slurry pipe 4 and " U " shape groove 51, leave the air flue 6 that enters for air, gases at high pressure in the air hose 2 enter in the rifle core 5 along air flue 6 and form bump for the first time with water-coal-slurry, water-coal-slurry is tentatively atomized, water-coal-slurry after the preliminary atomizing enters in " U " shape groove 52 along the through hole of offering on the connector 53 54, offer through hole 521 on the cell wall of " U " shape groove 52, gases at high pressure in the air hose 2 enter in " U " shape groove 52 along through hole 521 and carry out the bump second time with water-coal-slurry, and water-coal-slurry is atomized once more; Front end at rifle core 5 is provided with sprue 7, offer through hole 71 on the sprue 7, leave the air flue 8 that enters for the air in the air hose between sprue 7 and the rifle core 5, the gases at high pressure in the air hose 2 enter with water-coal-slurry along air flue 8 and clash into for the third time, and water-coal-slurry is further atomized; The place ahead of sprue 7 is provided with connector 3, and connector 3 is provided with the bolt 9 that adapts with annular muzzle, offers water-coal-slurry after through hole 31, the three times atomizing on the connector 3 through behind the through hole 31, along annular muzzle 12 ejections.
Because sleeve 1 is threaded with connector 3 and air hose 2, the size of whitewashing amount is regulated in the gap between therefore rotatable sleeve 1 annular muzzle 12 of adjusting and the bolt 9.This kind regulative mode does not change the proportioning of water-coal-slurry and air quantity, so can not influence the combustion conditions of burner hearth when regulating.
