Technical field
The present invention relates to mineral products field of mechanical technique, be specifically related to a kind of feeding filling system smoothly.
Background technology
At present, in mining operation, the exploitation of subterranean resource constantly destroys underground original material composition form, ground water field, initial rock stress field isoequilibrium, and forms Goaf Area in choosing.When the process of mining operations does not exceed the control range of setting, its operation process is safe; When the process of mining operations is out of control, when exceeding the control range of setting, such as roof fall, gushing water, surface subsidence, mud-rock flow or surface water will be there is and pour in the Mine safety accidents such as down-hole, extensive Ground pressure activity.The generation of these security incidents all has close contacting with the existence in goaf.If carry out high-quality filling to goaf in mining operations, above-mentioned security incident can obtain effective prevention and control, and therefore, casting resin bashing along with the propelling of stope, is progressively used in most of mine in ore extraction process.
When current employing mill tailings carries out filling to underground goaf, usual employing hydraulic fill method, be that 20-60% mine tailing is delivered directly to filling area by volumetric concentration, method is simple, efficiency is high, but following adverse effect will be caused: 1, because mine tailing granularity is very little, the mine tailing being filled with goaf needs long time to precipitate and dries up just can bear certain pressure, and follow-up ore needs just to proceed exploitation under the condition of certain pressure can be born in filling area, therefore hinder the exploitation of follow-up ore; 2, in mine tailing stowing operation, mine tailing tiny in a large number flows into shaft sump with current, causes shaft sump to deposit, and destroys mine down-hole drainage system.3, the water in a large amount of mine tailing flows into shaft sump with mine tailing, increases drainage underground amount, consumes a large amount of electric power.
Adopt dry filling method can avoid above-mentioned shortcoming, but current dry filling method generally adopts mine car or other machinery from the dry casting resin bashing of ground conveying, compared with hydraulic fill method, conevying efficiency is lower.
, mainly there is following problem in filling system of the prior art: is usually mixed with the excessive impurity of volume in mine tailing, and impurity enters fill system and easily causes system to shut down, and serious easily causes system failure, so be necessary to solve this problem.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of to pulverize mine tailing and the sieve that shakes, transfer efficiency are high, reduce the filling system of frequency of maintenance.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of feeding filling system smoothly, comprise mill, filter, vibrating sieving machine, feeding warehouse, rotary feeder, ejector, blower fan and filling pipeline, the feed end of described mill introduces Tailings Slurry by pipeline, the discharge end of described mill is connected by conveyer belt with described filter, the discharge end of described filter is in the upper end of described vibrating sieving machine, described vibrating sieving machine discharge end stretches in described feeding warehouse, the lower end of described feeding warehouse is communicated with the upper end of described rotary feeder, described rotary feeder discharge end is communicated with described filling pipeline by pipeline, described ejector is placed in the side of described filling pipeline, and the jet of described ejector stretches in described filling pipeline the side being in described rotary feeder lower end, the air outlet of described blower fan is communicated with the air intake of described ejector, the side of discharge outlet in described rotary feeder lower end away from described ejector jet of described filling pipeline.
The invention has the beneficial effects as follows: first Tailings Slurry is pulverized by mill, prevent from Tailings Slurry, being mixed into the larger impurity of volume, the sieve that shakes is carried out after utilizing filter to be dewatered by moisture Tailings Slurry, impurity excessive for volume is screened out, feeding warehouse utilizes the gravity decline of self to impact rotary feeder after storing, make rotary feeder uniform rotation to ejector feed, simultaneously blower fan air-supply provides filling power to blow dry mine tailing in ejector through filling pipeline to filling area, continually can carry out filling operation; Whole system configuration is simple, transfer efficiency is high, reduce frequency of maintenance, has low cost, high efficiency advantage; Overcome the defect waiting period that prior art utilizing water conservancy filling to need a large amount of electric power to need after the mine water drained Tailings Slurry and bring and filling, also overcome prior art dry stowing simultaneously and utilize mine car or other machinery to carry out the defect of bashing inefficiency from the dry casting resin of ground conveying.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described feeding warehouse comprises cylinder, and the lower end of described cylinder connects the circular cone bucket of convergent.
The beneficial effect of above-mentioned further scheme is adopted to be: to be convenient to dry mine tailing and to be easy to fall in rotary feeder in order, be convenient to later stage operation and carry out in order.
Further, described rotary feeder is connected by flange with between described feeding warehouse and filling pipeline, and described ejector is connected by flange with between described blower fan, filling pipeline.
The beneficial effect of above-mentioned further scheme is adopted to be: it is more firm that flange makes this device connect, and sealing is stronger.
