Abstract
The utility model relates to a quantitative feeder for a grout-making system for coal mine fire prevention and control, which can effectively prevent the arch camber of a conveyed material to ensure smooth conveying of a material for making grout, and can primarily crush materials with big particles. The quantitative feeder is provided with a feed hopper, a feed box, four parallel spiral conveyorshafts positioned in the feed box, and a driving device for the spiral conveyor shafts; a discharge hole of the quantitative feeder is positioned on the bottom of the feed box; rotating directions ofspiral conveyor blades of two spiral conveyor shafts positioned in the middle are opposite; and rotating directions of spiral conveyor blades of the outside two spiral conveyor shafts are the same asthat of a spiral conveyor blade of an adjacent spiral conveyor shaft.
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 quantitative feed machine that is used for the preventing and extinguishing fire of coal mine pulping system.
Background technology
At present pulping process commonly used is in the preventing and extinguishing fire of coal mine: sweep away mud with water blast gun on mound, it is flowed into concentrate the slurry ditch, flow into slip agitating tank after removing foreign material, import grouting pipeline after puddle mixer stirs.Also usefully manually pulping materials Zhao loess or fly ash are sent in the stirring pool, water filling puddle mixer stirring pulping again, its pulping process seldom uses the quantitative feed equipment, and the material that adds stirring pool like this can't accurate measurement, and concentration of slurry is also uncontrollable.Even pay-off is used in some anti-fire extinguishing slurrying, also be to adopt the general-duty feeder, and the anti-required loess consumption of mud of putting out a fire is very big, loess has viscosity preferably in addition, these general-duty feeders are difficult to adapt to the requirement of anti-fire extinguishing slurrying, in carrying the loess process, pile up easily or arch camber, and the material particles that transfers out is bigger, is difficult for dissolving.
Summary of the invention
Problem to be solved in the utility model provides a kind of quantitative feed machine that is used for the preventing and extinguishing fire of coal mine pulping system, and it can not only prevent the material conveying arch camber by actv., guarantees that the pulping materials conveying is smooth and easy, and also material that can particle is bigger carries out preliminary fragmentation.
The technical scheme that addresses the above problem is: the quantitative feed facility that are used for the preventing and extinguishing fire of coal mine pulping system that provided have feeder hopper, hopper, be positioned at four screw conveyor shafts arranged side by side of hopper and the actuating device of screw conveyor shaft, the discharging opening of quantitative feed machine is positioned at the hopper bottom, the rotation direction of the spiral conveying blade of two screw conveyor shafts in the middle of wherein being positioned at is opposite, and the rotation direction of the spiral conveying blade of the screw conveyor shaft that the spiral conveying blade of two screw conveyor shafts in the outside is adjacent is identical.Material enters hopper from feeder hopper, under the drive of screw conveyor shaft, push material to discharging opening, meanwhile, because the conveying blade rotation direction of two screw conveyor shafts in the middle of being positioned at is opposite, to carry out preliminary fragmentation to large granular materials, and make the material that arrives discharging opening be unlikely to pile up.The material that is broken is fallen by the discharging opening of hopper bottom, delivers to the mudding up machine by band conveyor again.
The actuating device of above-mentioned screw conveyor shaft preferably adopts frequency control motor, but the rotating speed of flexible screw conveyor shaft like this, and the demand of different feeding amounts when satisfying slurrying reaches the purpose of control operational throughput size.
In order further to prevent accumulation and the arch camber of material at the discharging opening place, an end of the every close discharging opening of screw conveyor shaft is equipped with a slice anti-leaf-pushing plate opposite with the spiral conveying blade rotation direction of this conveying axis.
The utility model adopts four screw conveyor shaft feedings, has not only strengthened the operational throughput of material, and can carry out preliminary fragmentation to the bigger material of particle, and actv. prevents the arch camber of slurrying material, but and flexible operational throughput.The utility model compact conformation, simple to operate, only need with pulping raw material send into quantitative feed machine hopper can realize continuously, by the purpose of setting operational throughput feeding, thereby improved work efficiency.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the view of Figure 1A-A direction.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
An embodiment of the present utility model as shown in Figure 1 and Figure 2.Feeder hopper 1 is installed in the frame first half, hopper 2 is positioned at below the feeder hopper, four screw conveyor shafts 3,4,5,6 have been installed in the hopper 2 side by side, frequency control motor 8 is by reductor 9 and be installed in four sprocket transmission devices drive screw conveyor shaft rotations on the screw conveyor shaft, the screw conveyor shaft 4 in the middle of wherein being positioned at and the direction of rotation of screw conveyor shaft 5, the rotation direction of their spiral conveying blade 10 is also opposite; And the screw conveyor shaft 3 in the outside is identical with the rotation direction of screw conveyor shaft 4, and screw conveyor shaft 6 is identical with the rotation direction of screw conveyor shaft 5.In addition, an end of the every close discharging opening of screw conveyor shaft also is provided with a slice anti-leaf-pushing plate 11 opposite with the spiral conveying blade rotation direction of this conveying axis.
In order further to strengthen the crushing effect to material, the blade of two screw conveyor shafts is to distribute like this in the middle of this example: look down from inlet point, two screw conveyor shafts 4 in the middle of being positioned at and 5 spiral conveying blade are to distribute symmetrically.
Variable-frequency motor 8 drives four screw conveyor shaft rotations by chain-driving during work, and material moves to discharging opening 7 under the promotion of conveying axis.Because opposite near two middle screw conveyor shaft blade rotation directions, so can produce the roll extrusion effect to material conveying in the rotary course, the material that particle is bigger carries out preliminary fragmentation.Discharging opening 7 is positioned at the hopper bottom, is a bigger rectangle hole, and material is fallen smoothly.When material is pulled to discharging opening 7, if it is untimely to run into blanking, then may pushedly cross discharging opening, the anti-leaf-pushing plate 11 on the screw conveyor shaft plays a role at this moment, and the repulsion of this blade can prevent that convey materials is because of in time falling the extruding accumulation that causes from discharging opening.Material falls behind down from discharging opening, falls the next stage equipment of anti-fire extinguishing pulping system.
