Description

Technical Field

[0001] The utility model relates to the field of fire prevention and extinguishing, in particular to a fire prevention and extinguishing pulping system. Background Art

[0002] Fire prevention and extinguishing in underground goaf and other environments is the top priority of safe production. In the existing technology, the windproof and fire-fighting means for relevant locations are generally closed filling. However, due to the low integration of pulping and filling equipment, the filling process construction process is cumbersome, maintenance is frequent, and the construction cost is high, resulting in many inconveniences in the implementation process.

[0003] Specifically, the filling equipment in the prior art generally uses a three-way or even a four-way pipeline to transport materials such as water glass, concrete, fly ash and inhibitors to the slurry pump, and cooperates with a disturbance plate in the pipeline at the output end of the pump body to stir the materials in the pipeline before directly filling. This construction process will not only cause uneven material mixing, but also cause problems such as pipe blockage. In particular, the material ratio is all artificially filled, and the quality of the prepared filling slurry cannot be guaranteed, and the filling effect cannot be guaranteed.

[0004] There is currently no corresponding solution to the above problems. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a fire-proof slurrying system which uses gangue slurry as the main material, reduces the filling cost accordingly, and has a high degree of integration from slurrying, mixing to filling, can automatically proportion various materials, and can prevent pipe blockage.

[0006] The equipment includes a gangue slurry conveying unit, a secondary slurry filtration mechanism, a water glass grouting unit, a stirring and grouting mechanism, a flushing unit and a control system;

[0007] The slurry conveying unit comprises a slurry conveying pump, and the slurry conveying pump pipeline is connected to the external slurry;

[0008] The slurry delivery pump is connected to the slurry secondary filtration mechanism through a primary slurry delivery pipeline, and the slurry secondary filtration mechanism is connected to an external water source through a water delivery pipeline;

[0009] The slurry secondary filtering mechanism includes a slurry making mechanism and a slurry filtering mechanism; the slurry making mechanism is used to proportion the slurry viscosity and perform secondary fine grinding of the slurry, and after proportioning and fine grinding of the slurry, the slurry is filtered through its slurry filtering mechanism, thereby preventing pipe blockage;

[0010] The slurry secondary filtration mechanism is connected to the stirring tank via a secondary slurry delivery pipeline;

[0011] The stirring tank is also connected to the water glass grouting unit through a water glass delivery pipeline;

[0012] That is to say, the secondary slurry delivery pipeline and the water glass grouting unit jointly deliver the slurry to the stirring tank in the stirring and grouting mechanism for stirring and mixing;

[0013] The mixing tank pipeline is connected to the grouting mechanism;

[0014] The flushing unit pipeline is connected to the secondary slurry filtering mechanism; it is used to immediately flush the secondary slurry filtering mechanism to prevent equipment clogging;

[0015] The control system signals connect the gangue slurry conveying unit, the slurry secondary filtering mechanism, the water glass grouting unit, the stirring and grouting mechanism and the flushing unit.

[0016] The effect achieved by this is: under the coordinated control of the control system, the gangue slurry passes through the gangue slurry conveying unit to the secondary slurry filtering mechanism, the slurry is secondary slurried and filtered by the secondary filtering mechanism, and enters the stirring tank in the stirring and grouting mechanism; the water glass grouting unit simultaneously injects water glass into the stirring tank, and after being stirred in the stirring tank, the grouting mechanism directly fills and grouts;

[0017] During the interval of grouting or after the grouting is stopped, the flushing unit flushes the secondary filter mechanism to prevent the equipment from being blocked or the pipe from being blocked.

[0018] The beneficial effects of the utility model are as follows: the utility model solves the problems of low integration and low mixing uniformity of filling fire extinguishing equipment in the prior art, inability to automatically proportion materials and easy pipe clogging, realizes highly integrated automatic grouting, can strictly control the proportion of each material, and thereby improves the grouting quality; in particular, the flushing unit can flush the secondary filtration mechanism of the slurry, solves the problem of equipment and pipeline clogging, and has great value for promotion and application.

[0027] The slurry secondary filtering mechanism 7 includes a slurry making mechanism and a slurry filtering mechanism; the slurry making mechanism is used to proportion the slurry viscosity and perform secondary fine grinding of the slurry, and after proportioning and fine grinding of the slurry, the slurry is filtered through its slurry filtering mechanism, thereby preventing pipe blockage;

[0028] The slurry secondary filtration mechanism 7 is connected to the stirring tank 4 through a secondary slurry delivery pipeline;

[0029] The stirring tank 4 is also connected to the water glass grouting unit through a water glass delivery pipeline;

[0030] Preferably, the water glass grouting unit injects the water glass material into the stirring tank 4 through the water glass delivery pump 6 .

[0031] That is to say, the secondary slurry delivery pipeline and the water glass grouting unit jointly deliver the slurry to the stirring tank 4 in the stirring and grouting mechanism for stirring and mixing;

[0034] The control system signals connect the gangue slurry conveying unit, the slurry secondary filtering mechanism 7, the water glass grouting unit, the stirring and grouting mechanism and the flushing unit.

[0035] Preferably, the grouting mechanism uses a grouting pump 5 as a slurry output device to grout the grouting working surface.

[0036] The effect achieved by this is: under the coordinated control of the control system, the gangue slurry passes through the gangue slurry conveying unit to the slurry secondary filtration mechanism 7, the slurry is secondary slurried and filtered by the secondary filtration mechanism 7, and enters the stirring tank 4 in the stirring and grouting mechanism; the water glass grouting unit simultaneously injects water glass into the stirring tank 4, and after being stirred in the stirring tank 4, the grouting mechanism directly fills and grouts;

[0037] During the grouting interval or after the grouting is stopped, the flushing unit flushes the secondary filter mechanism 7 to prevent the equipment from being blocked or the pipe from being blocked.

[0038] Furthermore, the flushing unit includes a water tank and a flushing pump 9, the flushing pump 9 is connected to the pulping mechanism through a flushing pipeline, and the flushing pipeline is connected to the primary slurry delivery pipeline through a tee.

[0046] In particular, the flow meter, regulating valve and the above-mentioned pumps are coordinated through the control system, so that the control system can flexibly control the pipeline flux and control the internal pressure of the pipeline within a safe range, thereby preventing operational failures or extreme situations such as pipeline blockage and pipe burst.

[0047] That is, by optimizing the relevant parameters of the control system, the pumping flow and pressure of the slurry pump 8 are automatically adjusted according to the grouting amount, and at the same time, the valve opening adjustment can effectively prevent the pressure of the conveying pipeline from being too high and causing a pipe burst.
