Description

Mining mobile cured foam device for filling
Technical field
The utility model relates to the mining equipment technical field, particularly a kind of mining mobile cured foam device for filling.
Background technology
Perfusion or pressure injection mud are the common methods that prevents spontaneous combustionof coal, puts out coal bed fire under the coal mine, the early stage mine of building mostly is provided with the ground grouting system, do not have the mine of ground grouting system then to be equipped with local filling system, annotate the sand system, annotate flyash system etc. as the down-hole in the part, down-hole.Many shortcomings such as investment is big, pipeline easily stops up, the down-hole pipeline long because the ground grouting system exists, the difficult control of flow, therefore New Built Mine seldom is provided with the ground grouting system, dispose local grouting equipment mostly in the down-hole, attal is transported near the underground filling place, directly mix the slurry pressure injection with equipment.This way is that anti-fire extinguishing operating cost or anti-fire extinguishing effect all are better than the ground grouting system.The early 1990s in last century, domesticly begin to occur the underground mobile grouting equipment, this equipment is orbit movable, can transport the underground work place easily to, realize the anti-fire extinguishing of larger area slip casting radiation with the small device input, the anti-fire extinguishing level of slip casting reaches a new level.At present domesticly still generally using this method, just charges (medium) develop into flyash, swell soil, coal drystone powder, mine tailing and gel, high percentage of water rapid solidifying material, organic synthesis charges etc. by original yellow mud, river sand etc.But with regard to anti-fire extinguishing operating cost and effect, still there is two large problems: the one, equipment adapts to the function singleness of charges; The 2nd, the charges freight volume is big; The 3rd, filling effect is not exclusively desirable, can't realize the tightness of filling still having cavity or space to exist after the water loss as the filling meson with water; The 4th, be not suitable for going up a hill zone and back emit the grouting filling of the cave that falls through, and the water loss meeting causes going down the hill regional water logging disaster.
Summary of the invention
The purpose of this utility model provide a kind of can the multiple medium of filling, make that multiple charges are synthetic after accurate proportioning to be solidified and have certain coefficient of foaming, do not have the mining mobile cured foam device for filling of water loss.
The utility model is to realize like this, it comprises cured foam filling car and mud filling car two parts, it is characterized in that mud filling car is by slush pump, mix stock tank, framework, the dry powder hopper, loam cake, motor, reductor, the dry powder flow meter, regulate dry powder flow speed changer, regulate the mud flow rate speed changer, dry powder supply flow rate controller and flat car are formed, it is provided with two dry powder hoppers that are respectively applied for into dress A material and B material, dry powder supply flow rate controller has been installed below the dry powder hopper, the charging aperture that mixes stock tank is connected with water flow controller with dry powder supply flow rate controller, A material mud discharging opening is connected by the mixed air drain of slush pump with cured foam filling car, B material mud discharging opening is connected by the slush pump of slush pump with cured foam filling car, slush pump is driven through speed changer by motor, cured foam filling car is by framework, speed changer, motor, loam cake, the mud medium safety valve, mix air drain, pressure meter, reductor, air compressor, slush pump, flat car is formed, mix on the air drain mud medium safety valve is installed, the cylinder of mud medium safety valve inflated and controls by air compressor in mixing air drain, the outlet of mud ditch is connected with slush pump, and slush pump is driven through speed changer by motor.
The utility model has the advantages that;
1, a tractor serves several purposes has the pressure injection gel, chemical foam takes place, mixes multiple functions such as slurry slip casting, pressure injection filler for mine cured foam;
2, the slurrying injecting paste material develops into the cured foam expander with certain multiple by entity material water mortar such as traditional loess, shale, mine spoil, flyash, mine tailings, the change entity is lightweight, significantly reduce filling cost, leak stopping wind effect significantly improves after the filling, especially can solve back and emit the cave that falls through, the coal seam anti-fire extinguishing problem in goaf of going up a hill;
3, slurrying uses material all to realize the stepless adjustable quantitative feed of flow, can effectively guarantee needed slurries quality.Especially it is very economic and practical that the dry powder flow is taked following frame mode supply.
