Description
Technical field:
The utility model relates to the preventing and extinguishing fire technology field of spontaneous fire in coal mine control, is specifically related to a kind of preventing and extinguishing fire of coal mine with continuous slurrying machine.
Background technology:
The anti-fire extinguishing of slip casting is one of conventional means of coal-mine fire control, is injected into ignition zone or appointed area by the mud that will prepare, and realizes fire extinguishing by the cooling oxygen barrier.The preparation of mud is that the pulping material such as clay and water are uniformly mixed to form slurries, and the residue that filters in the slurries by screen pack forms slurries.At present the pulping process at ground slurry preparing station is to sweep away mud with giant from mound, flows to the mud ditch, enters slip agitating tank after removing foreign material, injects stock line after mixer stirs.The method is because the water yield is uncontrollable, concentration of hydraulic mixture is also uncontrollable, because the time that pulping material contacts with water is short, still have a large amount of earth not melt in the slurries that leach, effects on slurry making is undesirable and utilization rate pulping material is lower, and mound field and stirring pool floor space are large in addition, and investment is large, labor strength is large, and efficiency is low.
Summary of the invention:
The utility model provides a kind of preventing and extinguishing fire of coal mine with continuous slurrying machine, and it can make the pulping material such as clay fully mix formation mud with water, filters the residue in the slurries, and forms the slurries of desired concn.
The technical scheme that addresses the above problem is: the preventing and extinguishing fire of coal mine that provides is with continuous slurrying machine, have a slurries cylinder and cylinder and a drive unit thereof that is contained in the slurries cylinder, slurries cylinder and drum-inclined are installed, charging aperture is located at the higher end of cylinder, slag notch is located at the cylinder other end, cylinder is provided with the deflector of slagging tap near an end of slag notch, it consists of near the thin-winding pipe on the slag notch end face by being fixed on cylinder; thin-winding pipe one end is that inner wall of rotary drum is close in the import of wedge shape residue; the other end passes cylinder and stretches to slurries cylinder outside near the centre bore on the slag notch end face and slurries cylinder near the centre bore on the slag notch end face; this end is slag notch; grout outlet is located at the slurries cylinder near an end of slag notch; cylinder is with screen pack near the periphery of slag notch part, is fixedly mounted with the stirring piece of axial setting on the inner wall of rotary drum.Drive unit drives drum rotating during use, pulping raw material enters in the cylinder by charging aperture, drum rotating plays a part to stir throwing to slurries, the axial stirring piece of inner wall of rotary drum makes the stirring throwing effect of cylinder stronger, slurries cylinder and drum-inclined are installed, slurries are moved to the screen pack direction, the screen pack that the slurries that stir pass on the cylinder enters the slurries cylinder, discharge by grout outlet, unfused clay is stayed in the cylinder, rotation by cylinder continues to melt, and to the drainage of slag notch direction, discharge by slag notch by residue with residue for the deflector of slagging tap.
Screen pack plays control mud to the distance between the charging aperture and is filtering the axially movable distance in forward position, and the inclination of cylinder is installed and played a part to regulate the mud translational speed control mud stirring time vertically, and the inclination established angle is generally 1～5 degree.
Leave certain space between cylinder and the slurries cylinder and play a part to store slurries, the grout outlet of slurries cylinder one end plays a part liquid volume in the regulating liquid surface height control slurries cylinder, leave time enough to slurries, unfused fine particle and water better merge in the slurries in order to make, and grout outlet is generally 25%～35% of slurries cylinder diameter to the height of slurries cylinder bottom.
The utility model employing slurries cylinder comprises the mode slurrying of cylinder, has strengthened the incorporation time of pulping material and water, has not only improved the utilization rate of clay, and has made slurries more even, and the pulping effect is more desirable.The utility model compact conformation, floor space is little, and small investment is simple to operate, only needs that the pulping material such as clay and water are sent into the slurrying machine and gets final product, and has realized the continuous slurrying deslagging, is conducive to work continuously, and has improved operating efficiency.
Description of drawings:
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the cutaway view of Figure 1A-A position.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
Such as Fig. 1; shown in Figure 2: slurries cylinder 1 is cylinder; slurries cylinder 1 plays a part to store slurries and as the protective cover of cylinder 2; slurries cylinder 1 and cylinder 2 tilt to install; the inclination established angle is generally 1～5 degree; charging aperture 3 is located at the higher end of cylinder 2; slag notch 4 is located at cylinder 2 other ends; cylinder 2 is provided with the deflector 10 of slagging tap near slag notch 4 one ends; it consists of by being fixed on the thin-winding pipe of cylinder 2 near the slag notch end face; thin-winding pipe one end is that cylinder 2 inwalls are close in wedge shape residue import 11; other end passes cylinder 2 and stretches to slurries cylinder 1 outside near the centre bore on slag notch 4 end faces and slurries cylinder 1 near the centre bore on slag notch 4 end faces; this end is slag notch 4; slurries cylinder 1 is provided with grout outlet 6 near an end of slag notch 4; cylinder 2 is with screen pack 5 near the periphery of slag notch 4 parts; be fixedly mounted with the stirring piece 9 of axial setting on cylinder 2 inwalls, and stirring piece 9 is generally 4～8 rows.
Drive unit 7 drives cylinder 2 rotations by transmission mechanism 8 during work, pulping raw material enters in the cylinder 2 by charging aperture 3, cylinder 2 rotations play a part to stir throwing to slurries, axially stirring piece 9 makes the stirring throwing effect of cylinder 2 stronger, because slurries cylinder 1 and cylinder 2 tilt to install, slurries move to screen pack 5 directions, the screen pack 5 that the slurries that stir pass on the cylinder 2 enters slurries cylinder 1, discharge from grout outlet 6, unfused clay is stayed in the cylinder 2, rotation by cylinder 2 continues to melt, and when the wedge shape residue import 11 of the deflector 10 of slagging tap was positioned at lower position, residue moved near the wedge shape residue import 11, when the wedge shape residue import 11 of the deflector 10 of slagging tap is positioned at the higher position, residue enters the deflector 10 of slagging tap, and along with the continuation rotation of cylinder 2, residue is discharged by slag notch 4.
