Technical field
The utility model relates to Cemented filling tailings slurry equipment in metal mine filling mining process, particularly a kind of tailings Slurry Pipeline Transportation damping device, be specially adapted to the tailing-filled mine that fed distance is far away, transporting resistance is large, slurry concentration is high, also can as damping device during other sticky materials of Cemented filling.
Background technique
Metal mine produces a large amount of CHARACTERISTICS OF TAILINGS SAND in ore dressing process, because its granularity is little, output large, piles up ground and can produce serious environmental pollution, simultaneously, metal mine can cause surface collapse in recovery process, damages farmland and surface structures, causes great economic loss to enterprise.For solving the problem, usual way is in CHARACTERISTICS OF TAILINGS SAND, add the cementing tailings slurry of appropriate cement production systD, and realizes gravity flow by Cemented filling and deliver to underground goaf and realize filling.This way solves tailings and piles up the environmental pollution problem caused on ground, serves again the effect supporting goaf top plate, prevents surface subsidence, protect surface structures and on-farm facilities.But still there are the following problems: because metal mine mining depth reaches more than km at present, down-hole horizontal pipeline is longer, transporting resistance is large, transfer efficiency is low, abrasion of conveying pipes is serious.
CN101275710A discloses a kind of drag reduction pipe, for the crude oil of transfer of highly viscous, grease and industrial chemicals, belongs to oil-gas transportation technical field.Pipeline is made up of inner and outer pipe, liquid or gas enter inner tube outer surface by honeycomb duct, axial groove again on interior pipe and hoop groove enter in pipe, by changing the frictional property of medium and wall, become liquid-solid friction into liquid-solid and gas-solid mixed friction, can make the surface friction drag reduction during high viscosity fluid such as conveying crude oil, grease and industrial chemicals in managing, efficiency of transmission improves greatly.But it is inapplicable on the conveyance conduit being applied to mining filling system.First, complex structure, considers the characteristic of CHARACTERISTICS OF TAILINGS SAND, the working strength of conveyance conduit, pipeline is directly offered groove and has a strong impact on its working life; In addition, pipeline configuration design is so complicated, adds fabricating cost and maintenance cost.
Summary of the invention
The purpose of this utility model is to provide a kind of structural design advantages of simple, easy to use and reliable tailings Slurry Pipeline Transportation damping device, extending fed distance, improving transfer efficiency, alleviating transducer wall ' s abrasion by reducing transporting resistance.
The technical solution of the utility model is:
A kind of tailings Slurry Pipeline Transportation damping device, it is characterized in that: comprise the slurry transition conduit that and two ends identical with slurry transportation pipeline internal diameter are respectively equipped with flange plate, described slurry transition conduit periphery is provided with ring seal shell, be provided with toroidal membrane in described ring seal shell and housing interior volume be separated into inner circumferential material overflow cavity and periphery water storage cavity, described toroidal membrane is extended to the other end by ring seal shell one end and leaves gap and be communicated with periphery water storage cavity by inner circumferential material overflow cavity, the position of the corresponding inner circumferential material overflow cavity of described slurry transition conduit offers water injection hole, the position of described ring seal shell corresponding periphery water storage cavity offers water filling hole, described water filling hole is connected with supercharging water supply system by water injecting pipe.
Above-mentioned tailings Slurry Pipeline Transportation damping device, described slurry transition conduit two ends are welded with flangeseal, so that be connected with slurry transportation pipeline.
Above-mentioned tailings Slurry Pipeline Transportation damping device, described water injection hole quantity is multiple, is evenly arranged in slurry transition conduit periphery.
The beneficial effects of the utility model are: enter in slurry transition conduit through periphery water storage cavity, inner circumferential material overflow cavity and water injection hole successively by water filling hole, thus high-pressure water flow is entered in slurry transportation pipeline by slurry transition conduit and washes away slurry transportation pipeline inwall, the tailings slurry material at tube wall place is diluted, water membrane is formed at tube wall place, i.e. boundary layer, the thickness in boundary layer is controlled by water injection rate.Tailings slurry material flow automatically in pipeline motion time, tailings particle and tube wall are separated by boundary layer, Cemented filling resistance is the shearing force that sheared edge interlayer needs, and this shearing force is far smaller than the shearing force that slurry material particles and tube wall produce, thus reaches the object of drag reduction anti-attrition.In addition, the damping device of the application has the internal diameter identical with slurry transportation pipeline and flange plate, is convenient to install, and this device adopts the method for water filling drag reduction to be easy to realize, and cost is low.
