Description
Technical field
The utility model relates to a kind of mine fire prevention fire extinguishing ground gel making device.
Background technology
The coal mine of China more than 50% has the spontaneous combustion problem, in case spontaneous combustion occurs then cause very big loss can for country, collective and personal property and life security.Some mines have begun to adopt ground slurry preparing and have been transported near the ignition point of down-hole by pipe network, are pressed into the fire district after sneaking into gel with miscellaneous equipment, make slurries realize the composite colloid preventing and extinguishing fire technology of quick extinguishing in the gelling of fire district.The mine that also has adopts at ground slurry preparing, adds then to have thickening and suspension materials with function in slurries, makes thickening colloid, and directly is pressed into the thickening colloid preventing and extinguishing fire technology of primer sector under the coal mine.These technology exist slurrying to lean on that Artificial Control, automaticity are low, concentration of slurry is difficult to guarantee and a difficult problem such as the carrier pipe Louis is stifled always.The preparation of particularly high underflow liquid (solid water than more than 1: 1) is most important to the composite colloid preventing and extinguishing fire technology, and present technology and equipment all can not realize automatically by loess, sand or flyash make high concentration, big flow, the requirement of the uniform suspension that can carry at a distance.Mainly show: 1, the concentration of slurry made of colliery water adding system too rare (soil ratio is more than 4: 1 usually), concentration of slurry is inhomogeneous and easy blocking pipeline, can not satisfy the requirement to slurries of composite colloid and thickening colloid; 2, filling extruding delivery technology can be realized high underflow liquid conveying but can not solve the slurrying problem; 3, existing pulper, foamed cement stowage unit etc. can be mixed and made into two kinds of material of solid-liquid underflow in proportion, but this equipment can only mix a kind of solid and a kind of liquid, and require the solid material granularity less, can not satisfy the needs of making finite concentration suspension slurry and colloid with the loess of different humidity automatically.Because in the injecting glue process, along with loose coal by the colloid filling, flow constantly changes, requirement can mix the composite colloid or the thickening colloid raw material (mainly being loess or flyash or sand etc. and water and additive) of big flow automatically in proportion, and can regulate each raw material supplying speed automatically according to changes in flow rate, keep proportioning constant, realize the good colloid of preparation continuously.And present equipment can not satisfy this requirement.
Summary of the invention
The technical problems to be solved in the utility model is can regulate the control concentration of slurry automatically for the deficiency that overcomes existing pulping technique and equipment provides a kind of, add other additive such as suspending agent in the trend slurries, satisfy the remote mine fire prevention fire extinguishing ground gel making device of carrying of slurries.
Technological improvement of the present utility model is: it has one-level agitator and secondary agitator, be communicated with by guiding gutter between these two agitators, flowmeter and electric control valve are housed on the water inlet pipe of one-level agitator, be provided with electromagnetic flowmeter on the delivery outlet of secondary agitator, the guiding gutter top also is provided with compound material feeder.
Further technological improvement of the present utility model is: one-level agitator and secondary agitator are propeller structure, they are parallel to each other, secondary agitator axis is lower than the axis of one-level agitator, and guiding gutter tilts to be connected between one-level agitator and the secondary agitator.
The good effect that the utility model produced: this device adopts two-stage to stir, thick slurry after one-level is stirred quantitatively adds behind the suspending agent through secondary again and stirs into screened stock and export, and by the flow of flowmeter and electromagnetic flowmeter detection water outlet and slurry, the concentration of slurry or colloid is determined in the two contrast.After this concentration signal feeds back to control circuit or computer, send the aperture of instruction adjustment electric control valve and the rotating speed of variable-frequency motor by control section again, realize the auto-control of concentration.Control section also can be according to the rotating speed of the flow signal of electromagnetic flowmeter and the additive of setting (as suspending agent) concentration adjustment variable-frequency motor, thereby regulates the blanking velocity of compound material feeder, realizes the automatic control of additive concentration.This device can accurately obtain the slurries or the colloid of predetermined concentration, can also add certain density additive in slurries automatically.The automation degree of equipment height, the slurries suspension is good, can save a large amount of labours, and production cost is low, can satisfy mine and other occasion is carried at a distance, the technology and the technological requirement of big flow injecting glue fire prevention fire extinguishing.

The specific embodiment
As shown in Figure 1 and Figure 2, be fixed with the one-level agitator 7 and the secondary agitator 13 that are made of propeller structure on frame 2, these two agitators are parallel to each other, but the position of secondary agitator 13 is lower than one-level agitator 7 (referring to Fig. 3).Bypass at one-level agitator 7 is connected with the water inlet pipe 10 that flowmeter 11 and electric control valve 9 are set, and hopper 18 is positioned at the top of one-level agitator 7 and is communicated with one-level agitator 7.Delivery outlet at secondary agitator 13 is provided with electromagnetic flowmeter 12.Variable-frequency motor 1 is transferred to belt pulley 5 by reductor 3 with power, makes the shaft of I and II agitator 7,13 realize interlock by belt pulley 5 and driving-belt.Be communicated with by the guiding gutter 8 that tilts to install between the I and II agitator 7,13, guiding gutter 8 tops are communicated with compound material feeder 16 again.Said compound material feeder 16 also is a propeller structure, and is driven by reductor 15 by variable-frequency motor 14.
Loess after fragmentation is entered in the one-level agitator 7 by hopper 18, and quantitatively is mixed into thick slurry with water by water inlet pipe 10 inputs, through guiding gutter 8 inflow secondary agitators 13.Simultaneously, by the compound material feeder 16 of variable-frequency motor 14 control the suspending agent weight feeds in the charging aperture 17 are flowed through in the thick slurry of guiding gutter 8.These thick slurries and suspending agent enter simultaneously and capablely again behind the secondary agitator 13 stir into screened stock and exported by delivery outlet.
The flow of this device water inlet is detected by flowmeter 11, regulates the flow size by electric control valve 9 again.The flow of output slurries is detected by electromagnetic flowmeter 12, and the concentration of slurries can be determined by pulp flow and flow of inlet water contrast.Said flowmeter 11, electromagnetic flowmeter 12, electric control valve 9 and variable-frequency motor 1,14 all link to each other with control circuit or computer, by the detected signal feedback of flowmeter to control circuit or computer, variable-frequency motor is controlled in the instruction of passing through again to be sent, and then control I and II agitator and compound material feeder and electric control valve, so can realize the automatic adjusting control of concentration of slurry, as long as preestablish flow and concentration, can be mixed with the slurries or the colloid of desired concn.
