Description
Technical field
The invention belongs to the ball mill in ore dressing plant-cyclone technical field, particularly relate to a kind of scalping cyclone overflow granularity and run thick autoalarm.
Background technology
In recent years, quickening along with preparation equipment maximization transformation progress, a grinding-classification operation in increasing ore dressing plant adopts the closed circuit ore grinding that carries out of ball mill-a cluster cyclone, reaching disposal ability when improving the ball milling board, to improve the automatic control level of grind grading, and realized reducing the purpose of unit ore grinding cost and be promoted application.
At present, one time grinding-classification operation adopts the technology of the automatic control of ball mill-a cluster cyclone closed circuit grinding ripe, detect and the parameter of control mainly contains raw ore (final products of broken process) mine-supplying quantity, the sand return water yield, the electric monitor of ball grinder amount of ball mill, the feed force of cyclone, give ore deposit flow, feed ore concentration, effluent concentration etc.In process of production, cyclone is often because equipment self or change that there will be two kinds of situations for the ore deposit condition, the one, cause sand settling mouth to stop up, cause cyclone not have the sand setting amount, the mine-supplying quantity of cyclone is directly flowed out from overflow pipe, cause oarse-grained ore (general diameter is between 3-20mm) to enter beneficiation flowsheet, have influence on production target and production direct motion, if untimely processing, even the production accident of meeting production development line clogging; The 2nd, occur sometimes running thick phenomenon, having part also can enter beneficiation flowsheet than granule ore (general diameter is between 3-8mm) affects production target.For both of these case, robot control system(RCS) can be processed (also not possessing this function in the most ore grinding robot control system(RCS) of this type of alarm) by setting to give to report to the police when the cyclone effluent concentration reaches a certain numerical value, in order to remind operating personnel in time to process.But adopt this mode following drawback of having reported to the police: a cluster cyclone spillway discharge is less, and set a cluster cyclone overflow gravity line is thicker, cause the overflow gravity line not carry by full packages, make concentration measuring apparatus mounted thereto can not bring into play its performance, measure error is also larger, the warning effect is undesirable, particularly the second runs thick situation, because a cluster cyclone spillway discharge changes little, the warning effect is more undesirable, often can not find in time that the cyclone overflow runs slightly, postpone time of pinpointing the problems and processing the cyclone equipment fault, even more serious on the impact of production target.
Summary of the invention
The purpose of this invention is to provide a kind of scalping cyclone overflow granularity and run thick autoalarm, improve in the metallic ore ore-dressing technique in primary ball mill-a cluster cyclone closed circuit grinding because of the cyclone granularity and run warning precision when thick.
The objective of the invention is to realize by following technical proposals:
Scalping cyclone overflow granularity of the present invention runs thick autoalarm, it is characterized in that the scummer by the spill box below that is located at described cyclone, be located at the flat screen on this scummer, be located at the image recognition sensor of this flat screen top, the central control computer that is connected of image recognition sensor therewith, the alarm signal generator, the monitor that are connected of central control computer forms therewith respectively.
The screen angle of described flat screen is between 10～45 °, and material is antifriction alloy, stainless steel or abrasive rubber.
Described alarm signal generator is audio output device.
Described image recognition sensor is wired image recognition sensor or wireless image identification sensor.
Operation principle of the present invention is: the overflow of cyclone enters spill box, the cyclone overflow feeds scummer through spill box, the sieve underflow stream of scummer enters beneficiation flowsheet, if the cyclone overflow granularity runs thick, (3～20mm) can not rest on the compass screen surface by scummer the rough grain of the race that contains in the overflow, thereby can avoid the cyclone overflow to run thick rear oarse-grained ore (general diameter is between 3-20mm) fully and enter beneficiation flowsheet, affect ore-dressing technique production direct motion.
Run rough grain if exist on the flat screen of scummer, the image recognition sensor that is arranged on the flat screen top of scummer obtains rough grain picture signal, and import this rough grain picture signal into central control computer and process, central control computer can be passed to alarm signal generator with alarm signal, alarm signal generator sends alarm signal, after operating personnel hear and report to the police, and confirm by monitor, thick reason is run in preliminary judgement, and in time processes the thick problem of running according to running thick reason.
The invention has the beneficial effects as follows: can find timely because of the cyclone equipment fault and change the overflow granularity that produces to the ore deposit condition to run thick, and the warning precision is high, after operating personnel hear and report to the police, and can confirm by remote monitor, the preliminary reason of judging that race is thick, concrete position, and carry out promptly and accurately processing according to running thick reason to running thick problem, avoid running the production that slightly brings because of long-time overflow granularity, quality, equipment breakdown, remedy in the grind grading automatic control control system, the error of traditional alert mode is large, and wrong report and not reporting does not know to run the deficiency of the thick order of severity etc. after the warning.
