Description

Description
Mine Foam Slurry Mixer I. Technical Field
The present invention relates to a mixer, in particular to a mine foam slurry mixer. II. Background Art
The spontaneous combustion of coal is one of the top hazards confronted in the safe production in coal mines in China, and it severely endangers the safety of workers in underground areas and the normal mining work at mining faces and may result in severe economic losses. As a leak stopping, oxygen exclusion, and fire prevention and control material, foam slurry will be a new trend of injection materials for fire prevention and control in coal mines, because it has high stability, high liquidity, and can avoid a grooving phenomenon that may occur when yellow mud (cement, coal ash) slurry is injected solely.
At present, there is no special foam slurry generator in coal mines; instead, conventional mobile injection apparatuses are used to agitate and mix a foaming agent and slurry, and the foaming process and mixing process are integrated under the agitation of a helical rod, resulting in severely degraded foaming ability of the foams; consequently, the foam expansion ratio of the foam slurry is low, and the bubbles are uneven and poor in stability; though agitators that are designed to mix foams with slurry are available in the traditional building material field, the agitators are inapplicable to narrow roadway spaces; in recent years, the preformed foam and yellow mud (cement, coal ash) slurry mixing process has been improved in the building material field: first, two high pressure fluids (foam liquid and slurry) are mixed through a three-way valve, and then the mixture is further mixed to a homogeneous state in a static mixer. However, in the mixing process, since the foam liquid is added in one operation, the foaming ratio is too high, about 40%; thus, the mixture is inapplicable to fire suppression. In addition, the foam slurry for mines must cure within a short time owing to the requirement for material properties on the site, and the viscosity of the foam slurry is much higher than the requirement of in-situ casting of ordinary foamed concrete. III. Contents of the Invention
In view of the drawbacks in the prior art, the present invention provides a mine foam slurry mixer, which can achieve a low foam breaking ratio and high foam mixing quality, and can be used to produce foam slurry in mass flow continuously.
To attain the object described above, the mine foam slurry mixer provided in the present invention comprises a mixer shell and a hollow helical rod mounted in the mixer shell; the mixer shell is arranged with a gas-liquid two-phase foam inlet on its front end, a slurry inlet on its lower end, and a manual valve and a foam slurry outlet on its rear end; the hollow helical rod is arranged with a front end bearing on its front end and a rear end bearing on its rear end; the front end bearing and rear end bearing are fixed inside the mixer shell via a supporting arm respectively; the hollow helical rod is a hollow rod, and has several spiral blades welded evenly on it and several flow guide ports arranged evenly along the rod; several power blades are mounted on the front part of the hollow helical rod right against the gas-liquid two-phase foam inlet, the mounting angle of power blade is 30-40°.

Preferably, the agitating paddles have paddle blades arranged helically on the circumference in two turns, with four paddle blades arranged evenly in each turn.
Preferably, the paddle blades are L-shaped paddle blades.
Preferably, the power blades are mounted at 35°.
Preferably, the power blades are in a quantity of three or four blades.

In addition, the mixer is simple in structure and easy to use? it can mix foams with slurry to a homogeneous state, and can produce foam slurry in a heavy flow continuously, to meet the user's demand.

V. Embodiments
Hereunder the present invention will be detailed description, with reference to the accompanying drawings.
As shown in Fig.l and Fig.3, the mine foam slurry mixer provided in the present invention comprises a mixer shell 7 and a hollow helical rod 5 mounted in the mixer shell 7; the mixer shell 7 is arranged with a gas-liquid two-phase foam inlet 1 on its front end, a slurry inlet 2 on its lower end, and a manual valve 15 and a foam slurry outlet 16 on its rear end; the hollow helical rod 5 is arranged with a front end bearing 3 on its front end and a rear end bearing 13 on its rear end; the front end bearing 3 and rear end bearing 13 are fixed inside the mixer shell 7 via a supporting arm 14 respectively; the hollow helical rod 5 is a hollow rod, and has several spiral blades 6 welded evenly on it and several flow guide ports 8 arranged evenly along the rod; several power blades 4 are mounted on the front part of the hollow helical rod 5 right against the gas-liquid two-phase foam inlet 1, the mounting angle is 30-40°.
Operating process: gas-liquid two-phase foams and yellow mud (cement, coal ash) slurry are fed into the mixer via the gas-liquid two-phase foam inlet 1 and the slurry inlet 2 respectively; wherein, the gas-liquid two-phase foams are guided into the mixer shell 7 via the flow guide ports 8 on the hollow helical rod 5, compared with adding foams in an one-off manner, adding foams through different flow guide ports 8 in stages can decrease the foam breaking ratio and improve the homogeneity of mixing between the foams and the slurry; the slurry spouted from the slurry inlet 2 impacts the power blades 4 mounted on the front part of the hollow helical rod 5 at a high speed, and thereby the hollow helical rod 5 is driven to rotate, at the same time, the foam liquid is jetted through the flow guide ports 8 on the hollow helical rod 5, the counter force of foam jet stream creates a kinetic moment on the hollow helical rod 5, and thereby the rotation speed and stability of the hollow helical rod 5 are improved; as the hollow helical rod 5 rotates, the foams and yellow mud (cement, coal ash) slurry move forward spirally, and thereby the quality of mixing between the foams and the slurry is improved. In addition, the mixer is simple in structure and easy to use, it can mix foams with slurry to a homogeneous state, and can produce foam slurry in a heavy flow continuously, to meet the user's demand.
As an improvement in the present invention, a coupling 9 and a solid shaft 11 can be mounted between the hollow helical rod 5 and the rear end bearing 13, the rear end of the hollow helical rod 5 is connected to the front end of the solid shaft 11 via the coupling 9; the rear end of the solid shaft 11 is connected to the rear end bearing 13; agitating paddles 12 are welded on the solid shaft 11; and the foam slurry that has been mixed by the rotation of the solid shaft 11 is agitated again through the agitating action of the agitating paddles 12, and thereby a phenomenon that the foams jetted through the flow guide ports 8 at the rear end of the hollow helical rod 5 are jetted directly from the foam slurry outlet 16 without being mixed with the slurry intensively can be avoided, and the homogeneity of mixing between the foams and the slurry can be improved.
Preferably, the agitating paddles 12 can be paddle blades arranged helically on the circumference, with four paddle blades welded evenly in each turn, and welded for two turns. Though the foams and the slurry can be mixed more intensively with more welded paddle blades, the self-resistance of the paddle blades will increase as the number of paddle blades increases, hindering the rotation of the paddle blades and the solid shaft 11 and adverse to the rotation of the hollow helical rod 5, and consequently the overall mixing between the foams and the slurry will be unsatisfactory; if paddle blades welded in one turn or two turns are used, the resistance will not be high, and the impact on the rotation of the hollow helical rod 5 and the solid shaft 11 will not be severe, while a satisfactory agitation and mixing effect of the foams and the slurry is attained. Preferably, the paddle blades can be L-shaped paddle blades. Compared with other structures, L-shaped paddle blades can attain a better agitating effect.
Preferably, the mounting angle of the power blades 4 is the included angle between the radial direction of the blade and the axial center line of the hollow helical rod, and is 30-40°, it is proved in tests that the power blades 4 can attain an optimal force transfer effect if they are mounted at 35° angle.
Preferably, the power blades 4 are in a quantity of three or four blades. If too many power blades 4 are provided, on one hand, the self-weight will be increased, and the resistance to rotation will be increased; on the other hand, the clearance between adjacent power blades 4 will be decreased, and the slurry jetted from the slurry inlet 2 may impact the edges of the power blades 4 instead of impacting the power blades 4 directly; consequently, the power blades cannot rotate and cannot drive the hollow helical rod 5 to rotate. As a result, the foams and the slurry canont be mixed. If power blades are too few, the power obtained by the power blades 4 from the impact of the slurry will be too low and it will be adverse to the rotation of power blades 4 to rotate satisfactorily. It is proved in tests that an optimal overall effect can be attained if three or four power blades 4 are used. Of course, the clearance between adjacent power blades 4 should be greater than the sectional area of the spout side of the slurry inlet 2, so as to mitigate the phenomenon that the slurry impacts the edges of the power blades.
Preferably, the opening direction of the flow guide port 8 is not in the center line of the hollow helical rod 5, compared with a scheme in which the opening direction of the flow guide port 8 is in the center line of the hollow helical rod 5, when the foam liquid is jetted through the flow guide port 8 on the hollow helical rod 5, the counter force of the foam jet stream creates a higher kinetic moment on the hollow helical rod 5.
As shown in Fig. 1 and Fig.2, spiral blades 6 are welded evenly on the hollow helical rod 5 in four and half turns, and five flow guide ports 8 are arranged evenly along the rod as gas-liquid two-phase foam outlets, with adjacent flow guide ports arranged at 72° spacing. In that configuration, the mixer can be used in narrow roadway spaces while it realizes mixing between foams and slurry; in addition, the mixing effect is optimal if adjacent flow guide ports are arranged at 72° spacing.
