Description
Technical field
The present invention relates to coal mine gob waste filling technical field.
Background technology
At present, in two technical problems of pit mining ubiquity: the one, a large amount of gangues is constantly carried to ground from the down-hole, occupies cultivated land that pile up like a mountain, and the pollution that hillock landslide, spontaneous combustion simultaneously brings also becomes the harm source of social recognition.The 2nd, the goaf natural caving causes roof caving, surface subsidence in the pit mining.In order to solve above-mentioned two problems, the someone takes not gug of spoil, direct mode in the underground filling goaf.This mode is called the waste filling technology.To be the down-hole be broken into particle powder below the 3mm with spoil to the waste filling technology relevant with the application, adds water and mix the back and be transported to the goaf with the spoil pump and carry out filling.Its weak point is, 1, because of the granularity of spoil fragmentation needs very carefully, so broken workload is big, efficient is low; 2, need to carry after the water mixing waste water source; 3, wet feed is carried and is caused pipeline blockage easily, influences normal filling operation.
Summary of the invention
For addressing the above problem, the invention provides the distinguished and admirable formula pipe waste rock discharge device of a kind of rotation.
Technical scheme is: it is made up of conveying worm, spiral air flow generator, wind cash blender and transfer pipeline, wherein:
The structure of spiral air flow generator is, be welded with helical wing plate in a segment pipe inner walls, one end of housing is the air intake that is connected with the down-hole pressure air pipe, and the other end of pipeline shell is as wind cash blender air intake, and it is distinguished and admirable to press wind to form rotation under the guiding of helical wing plate;
The structure of wind cash blender is, comprises one section pipeline shell greater than spiral air flow generator diameter of the housing, and an end of pipeline shell is as air intake, and is connected with the air outlet of spiral air flow generator; The tube wall end face of pipeline shell is provided with charging aperture, is tightly connected by charging aperture and conveying worm discharging opening; The other end of pipeline shell is set to tubaeform discharging opening, connects defeated cash pipeline by tubaeform discharging opening.
Operating principle is: spoil is crushed to spoil piece below the particle diameter 50mm, with conveying worm the spoil piece is delivered in the wind cash blender, the rotation that the spiral air flow generator produces is distinguished and admirable as power, under the distinguished and admirable effect of rotation, spoil and the distinguished and admirable homogeneous mixture that in blender, forms the gas-solid two-phase, and send from horn mouth, by defeated cash pipeline the spoil piece is delivered to the goaf.
Advantage of the present invention is:
The spoil piece footpath of 1, carrying is big, and broken spoil is easy, saves the broken time; Adopt dry feed, save the water source, and not sticky pipeline, transporting resistance is little, not plugging, and filling velocity is fast, the efficient height.
2, conveying worm advances the extruding of spoil stratum granulosum helical layer, forms obturator in machine, thoroughly eliminates pipeline inverted ventilation phenomenon.
3, the impact disturbance that produces of the spiral air flow generator material that will sink at BOP constantly blows afloat, and can effectively prevent gathering of tiny spoil particle, avoids line clogging.
4, the impact wind pressure that uses wind cash blender will rotate wind fully mixes with the spoil piece, forms gas-solid two-phase homogeneous mixture; And enter transfer pipeline with floating shape, and little to the frictional force of pipeline, can not cause the pipeline blockage problem.
5, transfer pipeline adopts macromolecule PE pipe, and the pipeline inner wall self lubricity is good, can effectively reduce the pipeline inner wall resistance, improves spoil particle transport speed; And have abrasion resistance, can use for a long time.
6, can adopt frequency-changing control system control conveying worm rotating speed, when filling operation face is longer, reduce the defeated cash amount of conveying worm, realize quantitatively remote the conveying; Otherwise work as filling operation face more in short-term, suitably improves the defeated cash amount of feeding screw, thereby how defeated the low coverage that realizes the work plane filling is.
7, owing to can realize carrying at a distance spoil, can make the downhole gangue whole fill, reduce the surface subsidence that the down-hole roof caving is caused, have good economy, society and safety benefit to the goaf.
