Abstract
The utility model relates to a vertical slurry preparation machine for extinguishment of a coal mine. The vertical slurry preparation machine can allow that slurry preparation materials such as clay are sufficiently mixed with water to form slurry liquid with required concentration. The vertical slurry preparation machine is provided with a circulating bucket and a slurry liquid bucket, wherein the height of the circulating bucket is lower than that of the slurry liquid bucket; the circulating bucket is inlaid on the side surface of the slurry liquid bucket; a feed port is formed at the top end of the circulating bucket; a slurry outlet is formed in the side surface, close to the bottom end, of the slurry liquid bucket; a deslagging port is formed at the bottom end of the circulating bucket; the slurry outlet is connected with a slurry outlet valve; the deslagging port is connected with a deslagging valve; and screen holes are formed in the side surface, located in the slurry liquid bucket, of the circulating bucket. During slurry preparation, the slurry outlet valve is opened, the deslagging valve is closed, the slurry preparation materials and the water enter the circulating bucket via the feed port, and the slurry liquid is formed under rotation of a circulating bucket stirrer, penetrates through the screen holes in the side surface of the circulating bucket, enters the slurry liquid bucket, and flows out via the slurry outlet and the slurry outlet valve; and during deslagging, feeding is suspended, the deslagging valve is opened, and residues are discharged via the deslagging port and the deslagging valve.
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 vertical slurrying machine for a kind of 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, 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 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 vertical slurrying machine for a kind of preventing and extinguishing fire of coal mine, it can make the pulping material such as clay be thoroughly mixed to form mud with water, filter the residue in mud, and form the slurries of desired concn.
The utility model solves the technical scheme that its technical problem adopts: vertical slurrying machine for the preventing and extinguishing fire of coal mine providing, there is a circulation barrel, a slurries bucket, a circulation barrel agitator, a slurries bucket agitator, a circulation barrel stirrer drive and a slurries bucket stirrer drive, circulation barrel and slurries bucket are cylindrical shape at right angle setting, circulation barrel height is less than slurries bucket height, circulation barrel is set in slurries bucket side, circulation barrel top is concordant with slurries bucket top, charging aperture is located at circulation barrel top, grout outlet is located at slurries bucket side by positon of near bottom, overfall is located at slurries bucket side near top end, circulation barrel bottom is provided with slag-drip opening, the part punching that circulation barrel side is positioned at slurries bucket inside has sieve aperture, grout outlet is connected with pulp valve, slag-drip opening is connected with slag-discharging valve.
When slurrying, slag-discharging valve is in closed condition, pulp valve is in opening, circulation barrel stirrer drive drives the rotation of circulation barrel agitator, slurries bucket stirrer drive drives the rotation of slurries bucket agitator, pulping material and water enter in circulation barrel by charging aperture, the rotation of circulation barrel agitator plays a part to be uniformly mixed to slurries, the sieve aperture that the slurries that are stirred are positioned at slurries bucket inside through circulation barrel side enters into slurries bucket, stirring by slurries bucket agitator further mixes, grout outlet and pulp valve by slurries bucket flow out, unfused clay is stayed in circulation barrel, continue to melt by the rotation of circulation barrel agitator, when deslagging, charging aperture suspends charging, residue after unlatching slag-discharging valve in circulation barrel and part slurries are discharged by slag-drip opening and slag-discharging valve, after deslagging, charging aperture continues charging, in the time that the slurries liquid level in slurries bucket is too high, slurries are discharged by overfall.
Circulation barrel bottom plays slurries bucket while being controlled at deslagging and stores the ability of slurries to the distance of slurries bucket bottom, circulation barrel bottom is generally 20%～60% of circulation barrel height to the distance of slurries bucket bottom.
The utility model employing circulation barrel is set in the mode slurrying of slurries bucket side, 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 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 slurrying machine, has improved operating efficiency.
