Description
Technical field
It is used for filling engineering the present invention relates to a kind of tailings harvester, more particularly to one kind, tailings can be made to liquefy rapidly,
To realize the harvester of pump piping conveying；Belong to the tailings floating collection of the construction operations such as mineral engineering, safety engineering
Device.
Background technology
During mine worked-out section filling construction operation is carried out, for the ease of gathering the tailings of filling in Tailings Dam,
Needing to liquefy tailings, make it have certain mobility, being conveyed with will pass through pump piping.
In order to ensure the flow effect of last mortar, the method generally directly impacted using current at present.I.e. man-hour manually hand-held is high
Pressure pipe directly carries out impact dilution against the tailings heap of deposition, and tailings gradually dilutes and with flowing in the presence of current
Property, smooth delivery of power is then realized by pipeline using immersible pump.This method is although simple and convenient, but last mortar uneven concentration,
Flowed fluctuation is big, causes immersible pump often in situation under feeding, or even stop.Frequently it is under feeding can to diving
The use of pump, which produces considerable influence, easily cause motor for submerged pump burns.In addition, current can only impact the surface of tailings heap, it is difficult
To go deep into inside it, therefore time-consuming longer, efficiency is low, and tailings is difficult to break up.3rd, water impact also has that water consumption is big, make
The defects such as industry cost height.4th, with the increase for adopting sand amount, it is necessary to be often moved to immersible pump from a goaf next
Acquisition zone；Not only efficiency is low, and operates also cumbersome.
Therefore, need badly exploitation it is a kind of it is simple in construction, easy to use efficiently, rapid inside tailings heap loose liquefied adopt can be made
Acquisition means.
The content of the invention
For drawbacks described above present in prior art, the present invention is intended to provide one kind is simple in construction, easy to use efficiently,
Rapid loose liquefied tailings liquefaction floating harvester inside tailings heap can be made.
To achieve these goals, the present invention uses following technical scheme：It includes immersible pump；Circular floating platform
On be fixed with mounting bracket, immersible pump is lifted on around the lower section of floating platform, immersible pump by the mounting bracket and is at least distributed with
Two sets are stirred sand liquefying plant；It is described stir sand liquefying plant by be fixed on mounting bracket playpipe, be fixed on the playpipe lower end
The sand liquefaction shower nozzle that stirs of mouth is constituted；Each playpipe is respectively by the water supply branch pipe with water supply check valve, with air feed check valve
Air feed branch pipe accordingly connected with water main, air feed house steward, air feed house steward connects with air compressor machine.
Sand liquefaction shower nozzle is stirred by the sealing shell connected with playpipe the, nozzle being supported on by bearing in the shell, solid
The impeller for being scheduled on the nipple top is constituted, and the lower end of nozzle is extended downwardly from from shell, and the surface distributed of the section of stretching out has some
The spray orifice tilted down from inside to outside；It is provided with each water supply branch pipe on water valve, each air feed branch pipe and air valve is installed；
It is provided with water main on water supply main valve, air feed house steward and air feed main valve is installed；Immersible pump is located at floating platform inner ring center
Lower section；Guard rail is fixed with floating platform.
Compared with the prior art, the present invention by adopting the above-described technical solution, using compressed air by atomization of water current simultaneously
Strong agitation is carried out to tailings, therefore can make quick loose inside tailings heap and reach fluidised form, smoothly realizes and is conveyed with pump sand.Separately
Outside, due to being stirred using compressed air, loose tailings, construction water can be not only greatly reduced, construction cost is reduced, and
And the big defect of tailings concentration fluctuation can also be effectively eliminated, therefore can avoid causing motor for submerged pump to damage due under feeding
Defect.3rd, as a result of said structure, floating platform position can automatically decline with the increase for adopting sand amount, eliminate
Conventional method need to often move the defect of immersible pump；Easy to operate, operating efficiency is high.
The present invention not only has simple in construction, easy to operate, tailings liquefaction efficiency height, the low advantage of construction cost, and
The labor intensity of operating personnel can also be reduced.
