Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of mining machinery, specifically refer to the automatic block clearing method and apparatus of a kind of mine fine ore bin feed opening blocking.
Background technology
At mine industry particularly gold, non-metals and the aluminous mine of China, measure more containing soil in viscosity or ore in ore, easily bond in fine ore bin.Especially when mineral water content is higher or south rainy day Mining Transport after, the non-constant of laxity of fine ore, often can cause fine ore bin feed opening to block.The blocking of fine ore bin feed opening can cause mill select production procedure discontinuous to ore deposit, even stop production and carry out plugging handling, serious impact and constrain the efficiency of production in ore dressing plant.The energy consumption made is high, productive costs rises, and meanwhile, causes production technology to fluctuate, affects production target and the percent recovery.
Traditional processing method is workman with iron hammer impact fine ore bin feed opening bulkhead, or uses long pricker to disclose feed opening mineral aggregate, and the labour intensity of this mode not only workman is large, and there is larger potential safety hazard.
In existing technology, publication number is disclose a kind of name in the patent of " CN201545391U " to be called " Manual material-through device for fine ore bins ".It comprises material bar and chain block, the lower end of described material bar is taper, the iron chains of described chain block with thoroughly expect that the upper end of bar is connected, this patent expects bar thoroughly by connecting one under chain block, the lower end of saturating material bar is taper, to facilitate insertion breeze, make to expect that bar moves downward and the feed opening of transmission ore storage bin by the iron chains of tractive chain block.This patent solves the dangerous problem that now artificial charge level thoroughly faces, and need not shut down and just thoroughly can expect work, avoids because the loss that causes of shutdown.
But above-mentioned glassware, for for the higher mineral aggregate of native more viscosity, is not only disclosed and it thoroughly also may not be made more to harden.Simultaneously for large-scale fine ore bin, the mineral thick-layer of tens meters cannot be penetrating with this glassware deadweight.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of automatic block clearing method and apparatus of mine fine ore bin feed opening blocking realizing automation mechanized operation, good blocking cleaning effect newly.
Technical scheme of the present invention is, first provides the automatic block clearing method of mine fine ore bin feed opening blocking, comprises the following steps:
A, first the data of the material level of ore storage bin, the frequency of operation of rock feeder and mine-supplying quantity to be gathered, set up mine-supplying quantity real-time curve simultaneously and lower ore deposit state is analyzed and judged, and set mine-supplying quantity lower limit.When the material level of fine ore bin is normal, the frequency of operation of rock feeder is normal, the real-time curve of mine-supplying quantity occurs abnormal, namely mine-supplying quantity lower than normal mine-supplying quantity and be less than mine-supplying quantity lower in limited time, can infer that the phenomenon blocked will occur the smooth or feed opening of fine ore bin blanking;
B, first the frequency of operation of rock feeder is adjusted to a certain high-frequency work district automatically, namely control the mine-supplying quantity tuning up rock feeder.Now, if mine-supplying quantity gos up, change obviously, illustrates that just blanking is not once in a while freely, automatically adjusted the frequency of operation of rock feeder, make mine-supplying quantity return normal mine-supplying quantity by control system; If obvious change does not occur mine-supplying quantity, then enter next step;
C, control system can be judged to be that feed opening blocks, then carry out vibrations to mineral aggregate in storehouse and loosen and block clearing process.
After adopting such scheme, first the present invention gathers the mine-supplying quantity data on the material level of ore storage bin, the frequency of operation of rock feeder and sealing-tape machine, simultaneously, the real-time curve setting up mine-supplying quantity is analyzed lower ore deposit state and judges, and sets mine-supplying quantity lower limit (as set 80% of normal mine-supplying quantity as mine-supplying quantity lower limit).When the material level of fine ore bin is normal, the frequency of operation of rock feeder is normal, the real-time curve of mine-supplying quantity lower than normal mine-supplying quantity and under being less than mine-supplying quantity in limited time, then infer that the phenomenon blocked will occur the smooth or feed opening of fine ore bin blanking.Now, first the frequency of operation of rock feeder can be adjusted to high-frequency work district automatically, namely control the mine-supplying quantity tuning up rock feeder.If now mine-supplying quantity gos up change obviously, illustrates that just blanking is not once in a while freely, automatically adjusted the frequency of operation of rock feeder by control system, make mine-supplying quantity return normal mine-supplying quantity.If obvious change does not occur mine-supplying quantity, then can judge that feed opening blocks, thus, vibrations be carried out to mineral aggregate in storehouse and loosens and block clearing process.Achieve in patent formula of the present invention and whether blocking is occurred to the feed opening of fine ore bin achieve automatic detection, and automatic block clearing process can be carried out when there is blocking.
As preferably, the loose and block clearing treatment measures of the vibrations described in step c are: install bunker wall vibration device in fine ore bin feed opening surrounding, when control system judges the blocking of fine ore bin feed opening, then start rapping apparatus and carry out loose ore deposit, the rapping time can be set to 3 ~ 10s.
Rapping terminates rear control system and can analyze ramping effect: if trend curve recovers normal (namely descend ore deposit normal, the mine-supplying quantity on sealing-tape machine is normal), fine ore bin feed opening latch up phenomenon is removed.If trend curve is still abnormal, system can start rapping apparatus for the second time, and so, generally after secondary rapping, the blanking of fine ore bin feed opening can recover normal.
Technical scheme of the present invention also provides the automatic block clearing device of a kind of mine fine ore bin feed opening blocking, adopt the automatic block clearing method of above-mentioned mine fine ore bin feed opening blocking, comprise fine ore bin, the below of described fine ore bin is provided with discharging opening, the top of described fine ore bin is provided with radar level gauge, the sidewall of described discharging opening is provided with vibrator, the below of described discharging opening is provided with rock feeder, the below of described rock feeder is provided with material transportation sealing-tape machine, is provided with belted electronic balance above described material transportation sealing-tape machine.Also comprise PLC, described PLC is connected with radar level gauge, vibrator, rock feeder, belted electronic balance and material transportation sealing-tape machine respectively.
Technique scheme of the present invention adopts the material level of radar level gauge to filler bin to detect, and use the feeding coal signal of PLC to the frequency of operation of level signals, rock feeder and belted electronic balance to process, then automatically control feeder and vibrator increase mine-supplying quantity or carry out rapping dredging blocking cleaning work.
As improvement, described PLC is also provided with upper computer, telltale, man-machine inputting equipment that described upper computer comprises main frame and is connected with main frame, and described main frame is electrically connected with PLC.Thus, this programme carrys out control signal collection by software, sets each desired parameters and carry out monitoring to multiple feed bin and operate.
As preferably, described radar level gauge is located at the Cang Ding center of fine ore bin.
