The utility model belongs to the technical field of coal mine fire prevention and extinguishment, discloses a drum pulping machine and solves the problems in the existing pulping method that impurities can not be effectively separated from grout, the grout concentration is low, pulping can not be continuously performed, and the labor intensity is high. The drum pulping machine comprises a drum with concentric conical bodies at two ends and a cylinder in the middle; a material inlet and a material outlet are arranged at two ends of the drum; a rotating blade is arranged on the inner wall of the conical body at the material outlet; the inner wall opening angle Alpha of the material inlet is larger than the inner wall opening angle Beta of the material outlet; the diameter of the material outlet is larger than that of the material inlet; the drum is supported and installed on a carrying roller of a frame; a driving device driving the drum to rotate through a gear ring outside the drum is also fixed on the frame; and the drum can rotate and move in positive and negative positions under the driving of the driving device. The drum pulping machine can effectively separate impurities, such as grass roots, stones and the like, from grout; the grout concentration is high, the flow quantity is large, continuous operation can be performed, and the labor intensity is greatly reduced; the service life is long; and the drum pulping machine has a simple structure, the floor space is small, the operation and the maintenance are simple, and the operating cost is low.
Description
Technical field
The utility model belongs to the preventing and extinguishing fire of coal mine technical field, relates to a kind of pulper that is used for preventing and extinguishing fire of coal mine, is specifically related to a kind of drum-type grout-making machine.
Background technology
The colliery freely burning fire is one of major casualty in the present Coal Production process, and preventative grouting is the method that China uses more a kind of effective prevention spontaneous combustionof coal.Can prepare the key factor that mud is the decision grouting effect by the concentration of design evenly and rapidly, and can not contain impurity such as grass roots and stone in the mud, in order to avoid stop up grouting pipeline.And pulper is the nucleus equipment of slurrying.Main at present sluicing slurrying and two kinds of pulping ways of stirring pool mechanical agitation slurrying of adopting.
Sluicing slurrying is to rely on sluicing table soil to make mud.The method can't effectively be filtered the impurity in the slurries, and concentration of slurry is extremely low.And owing to freeze, almost can't carry out sluicing slurrying operation winter at the northern China cold district.
The slurrying of stirring pool mechanical agitation is that loess is sent into mud pit, treats through soaking that earth used the Mixing Machine stirring pulping after soft in 2～3 hours.The problem of the impurity in the slurries can't be effectively filtered in the same existence of the method, and owing to be subjected to the restriction of stirring pool volume, the little and slurrying continuously of slurrying amount; And be deposited in the residue at the bottom of the pond, need the labor cleaning, labour intensity is big.
The utility model content
The utility model is for the impurity in the mud of can not separating that solves that existing pulping process exists, and easily stop up grouting pipeline, and concentration of slurry is low, slurrying is discontinuous, the problem that labour intensity is big, and a kind of drum-type grout-making machine is provided, to develop a kind of new pulping process.
The utility model is achieved through the following technical solutions:
A kind of drum-type grout-making machine, comprise that two ends are the concentric tapered body, the centre is cylindrical cylinder, the cylinder two ends are charging aperture and discharging opening, the bullet inwall of discharging opening one end is provided with rotating vane, the spacious angle α of the inwall of charging aperture one end is greater than the spacious angle β of the inwall of discharge port end, the discharging opening diameter is greater than the charging aperture diameter, cylinder is supported on the rack-mounted carrying roller, also be fixed with the drive unit that the gear ring head roll through the cylinder outside rotates on the frame, cylinder can rotate forward and reversely under the drive of drive unit.During slurrying, to join in the cylinder through loess and water the past endfeed mouth of accurate measurement, by being rotated in the forward of cylinder loess particle and water are risen to eminence and fall formation mud again, mud is owing to the effect of gravity is discharged by discharging opening, reduced the concentration of mud in the cylindrical shell in time, help the also fusion process of unfused particle more, for undissolvable stone, residues such as fragment of brick, can push it against the direction of charging aperture by the rotation of helical blade, and residue is stayed in the cylinder, and play the effect of abrasive material, quicken the dissolving of loess, can flow out together along with mud for low weight impurity, the filtration residue of process follow-up equipment falls into slag collecting pit.During deslagging, stop to add loess, continued water flowing operation pulper 5-20 minute, the powered-down of cutting off the water then, treat that cylinder is static fully after, oppositely start cylinder, promptly enter the deslagging state, rotation by helical blade can be pushed to discharging opening such as heavier impurity such as stone, brick etc., discharges via discharging opening, and the filtration of process follow-up equipment falls into slag collecting pit.
The mediate cylindrical inwall of described cylinder evenly is provided with lifting blade, loess and water is fully merged be prepared into uniform mud.
Described drive unit is a frequency control motor.
Described cylinder discharge port end cone also is connected with a uncovered short cylinder, and during use, short cylinder can better be connected with other machines.
Compared with prior art, the utlity model has following advantage:
(1) the utility model drum-type grout-making machine can effectively separate with stone impurity in the mud such as grass roots with tapping process by slurrying.Improve the quality of mud, thereby avoided the generation of plugging phenomenon in the slip casting process;
(2) mud amount that the utility model can be required according to reality is worked continuously, and is greatly reduced labour intensity, and concentration of slurry height, flow are big;
(3) all drive disk assemblies of the utility model equipment are located at the outside of cylinder, have avoided contacting with mud, and application life is long;
(4) the utility model is simple in structure, and floor space is little, and Operation and Maintenance is simple, and running cost is low, only needs loess and water are sent into equipment, can prepare anti-fire extinguishing mud continuously fast.
