Background technology
Filling in mine is the solid waste producing during big argument processes mining, improves the important of resource utilization
Means.The technique of general filling system joins cementing filling method using crude tailings, and current filling in mine generally adopts earth's surface system
Standby, high dense fill slip passes through pipeline to down-hole.
In consolidated fill system, especially highly concentrated cemented fill system, the filling slurry of preparation does not require nothing more than to be had
Higher concentration, ensures that it being capable of smooth delivery of power simultaneously again.The flowing that the change of water content very little all can affect filling slurry is special
Property and manage defeated resistance, and pipeline length is generally in more than 1km, if local concentration is too high, pipeline plugging accident easily, and it is difficult to process
Degree is big.The artificial block clearing mode poor stability generally adopting, efficiency is low, high cost.Therefore, control the steady of filling slurry concentration
Fixed, prevention line clogging is particularly important for filling system reliability.
Prevention line clogging at present generally adopts the method controlling packing density it is ensured that Filling density is stable, or keeps relatively low
Filling density, the former is relatively difficult to achieve, latter reduces the economy of filling, causes the problem of pollution after filling.
Utility model content
The technical problems to be solved in the utility model is：Overcome the deficiencies in the prior art, a kind of filling of economic and reliable is provided
The anti-blocking pipe device of extender paste delivery pipe, this device can accurately measure pressure reduction, by being monitored to the concentration in pipeline and then in advance
Anti- line clogging.
This utility model solves its technical problem and be employed technical scheme comprise that：A kind of filling slurry delivery pipe pipe-blocking-proof dress
Put, including filling slurry pipeline, pressure transducer, controller and automatically controlled exhaust-valve, two in filling slurry pipeline different high
One pressure transducer is respectively equipped with journey, pressure transducer connects the input of controller, automatically controlled exhaust-valve is fixed on filling
On slip pipeline, automatically controlled exhaust-valve connects the outfan of controller.
Further, it is provided with a rubber inner tube in described filling slurry pipeline, preferably, hardness is moderate, inner wall smooth for elasticity.
Further, leave space between described rubber inner tube and filling slurry pipeline.
Further, described automatically controlled exhaust-valve is fixed on filling slurry pipeline, and connects with rubber inner tube.
Further, leave the space of 20 ~ 40mm between described rubber inner tube and filling slurry pipeline.
Further, leave the space of 25 ~ 35mm between described rubber inner tube and filling slurry pipeline.
Further, described filling slurry duct wall is provided with electric control exhaust valve, and described electric control exhaust valve is connected to filling slurry
On pipeline.
Further, described electric control exhaust valve connects the outfan of controller.
The beneficial effects of the utility model：
（1）This apparatus structure is simple, and low cost is automatically drained out excessive concentrations slip by pipeline thus realizing pre- pipe-blocking-proof
Effect, effectively prevents the generation of pipeline plugging accident；
（2）Rubber inner tube is added, when concentration is excessive, electric control exhaust valve extracts in filling slurry pipeline and rubber in device
Air between pipe, makes slip smoothly flow down using the tension force of rubber inner tube, and after pipeline is unobstructed, electric control exhaust valve cuts out, in rubber
Pipe restores to the original state, and reliability is high, improves filling system reliability.
Brief description

Fig. 2 is the structural representation of this utility model embodiment 2.
In figure：1. the filling slurry pipeline 2. pressure transducer 3. automatically controlled row of automatically controlled exhaust-valve 4. rubber inner tube 5.
Air valve.
Specific embodiment
Below in conjunction with drawings and Examples, this utility model is described in further detail.
Embodiment 1
As shown in Figure 1：A kind of anti-blocking pipe device of filling slurry delivery pipe, including filling slurry pipeline 1, pressure transducer 2,
Controller and automatically controlled exhaust-valve 3, are respectively equipped with a pressure transducer 2, pressure on two different elevations of filling slurry pipeline 1
Force transducer 2 connects the input of controller, and automatically controlled exhaust-valve 3 is fixed on filling slurry pipeline 1, and automatically controlled exhaust-valve 3 connects
The outfan of controller.
The work process of the present embodiment：Slip flows into from filling slurry pipeline 1 entrance, two on filling slurry pipeline 1
Pressure reduction between two measuring points under the conditions of pressure transducer 2 measurement slip, pressure transducer 2 transmits pressure signal to controller, controls
Device processed is by being calculated the pressure reduction of two neighboring absolute altitude, and inquires about the data base of pressure difference corresponding concentration, determines this absolute altitude model
Concentration value in enclosing, if excessive concentration, controller controls automatically controlled exhaust-valve 3 to open, and discharges excessive concentrations slip, works as pressure difference value
It is reduced to normal range, that is, concentration is reduced to automatically controlled exhaust-valve 3 during stability range and closes, by that analogy.
Embodiment 2
As shown in Figure 2：The present embodiment is with the difference of embodiment 1, is provided with a rubber inner tube 4 in filling slurry pipeline 1,
Preferably, hardness is moderate, inner wall smooth, and slip will not be made to stick on inwall for elasticity；Rubber inner tube 4 and filling slurry pipeline 1 it
Between leave the space of 30mm, make rubber inner tube wall energy free-extension；Filling slurry duct wall is provided with electric control exhaust valve 5, automatically controlled row
Air valve 5 connects the outfan of controller, and automatically controlled exhaust-valve 3 is located at the lower end of electric control exhaust valve 5.
The other the same as in Example 1.
The work process of the present embodiment：Slip flows into from rubber inner tube 4 entrance, and pressure transducer 2 is by the pressure sensing
, to controller, controller is by being calculated the pressure reduction of two neighboring absolute altitude, and inquires about pressure difference corresponding concentration for signal transmission
Data base, determines the concentration value in this elevation range, if excessive concentration, controller controls electric control exhaust valve 5 to open, filling slurry
Air between pipeline 1 and rubber inner tube 4 is discharged, and the pressure between filling slurry pipeline 1 and rubber inner tube 4 diminishes, and makes in rubber
Tube wall is expanded, so that slip smoothly flows out；Can be when pulp density exceed lower limit, controller controls electric control exhaust valve 5
Open, automatically controlled exhaust-valve 3 is closed, and so that slip is smoothly flowed out, when pulp density recovers to stability range, electric control exhaust valve 5 closes
Close；Can also be too high in pulp density, rubber inner tube 4 is expanded when being also insufficient to allow slip smoothly to flow down, and controller controls electricity again
Control exhaust-valve 3 is opened, the dual function of the expansion of rubber inner tube wall and automatically controlled exhaust-valve 3, so that slip is quickly flowed out；Work as pulp density
When recovering to stability range, electric control exhaust valve 5 and automatically controlled exhaust-valve 3 are closed, by that analogy.
The above is only preferred implementation of the present utility model, but the not limit to this utility model protection domain
System, the variations and alternatives made in all application range in this utility model, should be included in protection domain of the present utility model.
