Abstract
The utility model discloses a continuous slurry preparation machine used for fire proofing and extinguishment in a coal mine. The continuous slurry preparation machine is provided with a liquid slurry tank, a rotary drum contained in the liquid slurry tank, and a drive device for the rotary drum, wherein the rotary drum is composed of a cylindrical section and a cone stage section, a feed port is arranged on the end surface of the cylindrical section of the rotary drum, a slag hole is arranged on the end surface of the cone stage of the rotary drum, a slurry port is arranged at the end of the liquid slurry tank, close to the slag hole, a filter screen is arranged at the periphery at the slag hole of the rotary drum, and stirring sheets and spiral guide sheets which are axially arranged are fixed on the inner wall of the rotary drum. In the continuous slurry preparation machine, slurry preparing materials become liquid slurry under the stirring of the stirring sheets, the liquid slurry is pushed towards the filter screen by the spiral guide sheets of the rotary drum, the liquid slurry enters the liquid slurry tank through the filter screen and is discharged through the slurry port, and slags are pushed towards the slag hole and are discharged from the slag hole.
Description
Technical field
The utility model relates to the preventing and extinguishing fire technology field of colliery freely burning fire, is specifically related to a kind of continuous slurrying machine that is used for preventing and extinguishing fire of coal mine.
Background technology
The anti-fire extinguishing of slip casting is one of conventional means of coal-mine fire control, through the mud for preparing being injected into the ignition zone, realizes fire extinguishing through the cooling oxygen barrier.The preparation of mud is pulping material such as clay to be mixed with water form slurries, filters the residue in the slurries through screen pack.At present the pulping process at ground slurry preparing station is to sweep away mud with giant from mound, flows to the mud ditch, gets into slip agitating tank after removing foreign material, stirs back injection stock line through mixer.The method because the time that pulping material contacts with water is short, still has a large amount of earth not melt because the water yield is uncontrollable, and concentration of hydraulic mixture is also uncontrollable in the slurries that leach, effects on slurry making is undesirable and utilization rate pulping material is lower.Mound field and stirring pool floor space are big in addition, and investment is big, and labor strength is big, and efficiency is low.
Summary of the invention
The utility model provides a kind of continuous slurrying machine that is used for preventing and extinguishing fire of coal mine, and it can make 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 continuous slurrying machine that is provided; Have a slurries tube and a cylinder and a drive unit thereof that is contained in the slurries tube, cylinder is made up of cylindrical section and frustum of a cone section, and charging aperture is located at the end face of cylinder cylindrical section; Slag notch is located at the end face of cylinder frustum of a cone section; Grout outlet is located at the end of slurries tube near slag notch, and cylinder is with screen pack near the periphery of slag notch part, installs the stirring piece and the spiral flow deflector of axial setting on the inner wall of rotary drum.Drive device drives cylinder rotation during use, pulping material gets in the cylinder through charging aperture, and the cylinder rotation 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; The spiral flow deflector of inner wall of rotary drum is passed slurries to the screen pack direction, the screen pack that the slurries that stir pass on the cylinder gets into the slurries tube, discharges through grout outlet; Unfused clay is stayed in the cylinder; Rotation by cylinder continues to melt, and the spiral flow deflector of cylinder is passed residue to the slag notch direction, and residue is discharged through slag notch.
Screen pack plays control mud to the distance between the charging aperture and is filtering the axially movable distance in forward position; The pitch of inner wall of rotary drum spiral flow deflector plays a part to regulate mud translational speed control mud mixing time vertically, and pitch is generally 5%～20% of drum length.
Leave certain space between cylinder and the slurries tube and play a part to store slurries; The grout outlet of slurries tube one end plays a part to regulate liquid volume in the liquid surface height controlling slurries tube; Leave time enough to slurries; Unfused fine particle and water better merge in the slurries so that make, and grout outlet is generally 10%～35% of slurries tube diameter to the height of slurries tube bottom.
The utility model employing slurries tube 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 desirable more.The utility model compact conformation, floor space is little, and small investment is simple to operate, only needs that pulping material such as clay and water are sent into pulper and gets final product, and has realized continuous slurrying deslagging, helps working continuously, and has improved operating efficiency.

Fig. 2 is the drum structural representation.
Fig. 3 is the sectional view of Figure 1A-A position.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to specify.
Like Fig. 1, shown in Figure 2: slurries tube (1) is a cylinder; The cover plate at its two ends is circular; The slurries tube plays a part to store slurries and as the protective cover of cylinder (2), cylinder (2) is made up of cylindrical section and frustum of a cone section, and charging aperture (3) is located at the end face of cylinder (2) cylindrical section; Slag notch (4) is located at the end face of cylinder (2) frustum of a cone section; Slurries tube (1) is provided with grout outlet (6) near an end of slag notch (4), and cylinder (2) is with screen pack (5) near the periphery of slag notch (4) part, installs the stirring piece (9) and the spiral flow deflector (10) of axial setting on cylinder (2) the cylindrical section inwall; Stirring piece (9) is generally 4～8 rows, and the pitch of spiral flow deflector (10) is generally 5%～20% of cylinder (2) length.
Drive unit during work (7) drives cylinder (2) rotation through transmission mechanism (8); Cylinder (2) is rotated in a clockwise direction (seeing to the slag notch direction from charging aperture) with certain speed, and pulping material gets in the cylinder (2) through charging aperture (3), and cylinder (2) rotation plays a part to stir throwing to slurries; Axially stirring piece (9) makes the stirring throwing effect of cylinder (2) stronger; The spiral flow deflector (10) of cylinder (2) is passed slurries to screen pack (5) direction, the screen pack (5) that the slurries that stir pass on the cylinder (2) gets into slurries tubes (1), discharges from grout outlet (6); Unfused clay is stayed in the cylinder (2); Rotation by cylinder (2) continues to melt, and the residue after the spiral flow deflector (10) of cylinder (2) will filter is passed to slag notch (4) direction, discharges from slag notch (4).
