The present invention prevents and treats the three-phase froth generating means of spontaneous combustionof coal, the polylith balk board that is provided with in blender is arranged crosswise at a certain distance, jet regulator comprises connecting axle and is made up of the current collector, impeller and the adjusting rod that are located on the connecting axle, connecting axle is arranged on the adjusting rod middle part of perpendicular setting, the impeller that is located on the connecting axle is located at by adjusting rod one end, with connecting axle movingly.
(3) technique effect
The present invention prevents and treats the three-phase froth generating means of spontaneous combustionof coal, is best suited for to put out fast under the coal mine and the high-efficiency prevention and control Conflagration Caused by Coal Self-ignition.Employing is at yellow mud or coal ash pulp; the feed pipe of blowing agent blends and be provided with the blender that the polylith balk board is housed is set between the foam maker cylindrical shell of Venturi tube; the gas pipeline of injecting gas is housed on the foam maker cylindrical shell; larynx eck place is provided with jet regulator in the cylindrical shell; the pressure that utilizes Flow of Goods and Materials to impact; impeller in the cylindrical shell rotates under the promotion of flowable materials voluntarily; the three-phase froth exquisiteness that produces; stable; compared with prior art; foam-making apparatus does not need spcific power; material is difficult for plugging; use reliably, adapt to the slurry material of different solid grain size, through field experiment; when the buck mass ratio of coal ash pulp or yellow mud is 1: 3; coefficient of foaming is 30 times, and the foam stabilization time reached more than 12 hours, and the commute ember plays a very good protection; and can effectively put out a fire to the fire that takes place; its compact conformation is reasonable, is convenient to safeguard to have practicality widely.
Four, description of drawings:
Accompanying drawing 1 is a main TV structure schematic diagram of the present invention.
Accompanying drawing 2 is plan structure schematic diagrames of the present invention.
Five, the specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are described further:
The present invention prevents and treats the three-phase froth generating means of spontaneous combustionof coal, it is mainly by the feed pipe 1 of yellow mud or coal ash pulp, blowing agent blends, blender 2 and foam maker are formed, foam maker cylindrical shell 7 is equipped with Venturi tube 5 with the connection place of blender 2, blender 2 is located between foam maker cylindrical shell 7 and the feed pipe 1, welding polylith rectangle balk board 3 in blender 2, balk board 3 is arranged crosswise at a certain distance, as labyrinth structure.When the slurries of mixture pass through blender 2, be subjected to the third party obstruction of balk board 3 in the passage, form turbulent condition in the motion, in short distance, blowing agent is mixed in slurries.The foam maker cylindrical shell 7 of corresponding Venturi tube 5 larynx neck positions is provided with the gas pipeline 4 of injecting gas, the periphery of Venturi tube 5 is provided with the hole 6 of a plurality of introducing gases, its larynx eck place is provided with jet regulator, jet regulator comprises connecting axle 9 and by the current collector 8 that is located on the connecting axle 9, impeller 10, adjusting rod 12 is formed, connecting axle 9 is arranged on adjusting rod 12 middle parts of perpendicular setting, impeller 10 on the connecting axle 9 is located at by adjusting rod 12 1 ends, with connecting axle 9 movingly, blade on the impeller 10 is established certain inclination angle, by the rotation of slurry powered, can increase the stability of foam, and make foam fine and smooth more, evenly.When the slurries that contain blowing agent enter in the foam maker cylindrical shell 7 of Venturi tube 5 form of structure, slurries are passing through Venturi tube 5, after being subjected to current collector 8 resistances again, the flow velocity of mud increases, static pressure reduces, form negative pressuren zone, make a plurality of gas holes 6 that gas passes through Venturi tube 5 peripheries by injection in grouting pipeline, thereby produce the three-phase froth 13 of higher multiple.For adapting to the slurry material of different solid grain size, the afterbody of foam maker cylindrical shell 7 is provided with and can moves forward and backward the slideway 11 of regulating current collector 8.
