Background technology
The anti-fire extinguishing of slip casting is one of conventional means of coal-mine fire control, and the slurries that prepare are injected into ignition region or appointed area, realizes fire extinguishing by cooling oxygen barrier.The preparation of slurries is that the pulping material such as clay and water are uniformly mixed to form to mud, and the residue filtering in mud by screen pack forms slurries.At present the main pulping process at ground slurry preparing station is to sweep away mud with giant from mound, flows to mud ditch, enters slip agitating tank after removing foreign material, forms slurries injection stock line after mixer stirs.The method is because the water yield is uncontrollable, and concentration of slurry is also uncontrollable, because the time that pulping material contacts with water is short, still has a large amount of earth not melt in the slurries that leach, and effects on slurry making utilization rate undesirable and pulping material is lower.At northern China cold district, winter temperature, usually in subzero, cannot carry out the outdoor operation of washing away.Mound field and stirring pool floor space are large in addition, and investment is large, and labor strength is large, and efficiency is low.
Summary of the invention
In order to overcome existing pulping system in the deficiency aspect concentration of slurry and pulping material utilization rate, the utility model provides a kind of preventing and extinguishing fire of coal mine continuous slurrying machine, it can make the pulping material such as clay be thoroughly mixed to form mud with water, filter the residue in mud, and forming the slurries of desired concn, slurrying efficiency is high.
The utility model solves the technical scheme that its technical problem adopts: the preventing and extinguishing fire of coal mine providing continuous slurrying machine, there is a hybrid chamber, a shaft, shaft drive unit, be fixed on stirring disc and deslagging disc on shaft, the agitator being connected with stirring disc, the slagging device being connected with deslagging disc, hybrid chamber is that cylindrical shape level is installed, charging aperture is located at hybrid chamber top near hybrid chamber end face, slag-drip opening is located at hybrid chamber side near the hybrid chamber other end, hybrid chamber is provided with pulp mechanism near slag-drip opening end face bottom, large one end, pulp mechanism one end is little, the large end of pulp mechanism is provided with screen pack, be connected with hybrid chamber, pulp mechanism small end is grout outlet.
When use, shaft drive unit passes through shaft, stir disc and deslagging disc and drive agitator and slagging device rotation, pulping material and water enter in hybrid chamber by charging aperture, agitator rotation plays a part rapid stirring to slurries and mixes, and makes slurries move axially along hybrid chamber simultaneously, and the slurries that are stirred flow out from grout outlet through the screen pack of pulp mechanism, residue in slurries moves to slag-drip opening one end under the stirring of agitator, is rotated from slag-drip opening and is discharged by slagging device.
Above-mentioned agitator has two faces, and each face is triangle, and two face angles are acute angle.
Above-mentioned deslagging disc end is bent into right angle.
Above-mentioned slagging device is bent into certain angle at middle part, slagging device is hinged in bending place and deslagging disc, slagging device one end is connected with buffer spring by bolt with deslagging disc end, the slagging device other end is free end, be close to hybrid chamber inwall, if running into hard thing in rotary course, slagging device is stuck between slagging device and hybrid chamber inwall, slagging device inwardly swings, spring-compressed, avoid the collision between slagging device and hybrid chamber inwall, in the time that slagging device rotates to slag-drip opening, residue is discharged by slag-drip opening.
The utility model adopts shaft to drive the mode slurrying of agitator, slurries rapid stirring in hybrid chamber is mixed, not only improved the utilization rate of clay, and made slurries more even, pulping effect is more desirable, the utility model compact conformation, floor space is little, and small investment is simple to operate, only the pulping material such as clay and water need be sent into pulper, improve operating efficiency.
