Description
Affiliated technical field
The utility model relates to ball mill automation control, especially improves ball mill operating efficiency, economize on electricity, water saving, saving finished product ' steel ball, liner plate ' loss, can allow the limited energy of country realize rationally efficient the utilization.
Background technology
Existing on the market at present technology combines by microcomputer or PLC, and volume is big, cost is high, installation is loaded down with trivial details, use complexity to be operated by the professional and technical personnel, and the concentration sensor error is big, fault rate is high, is difficult to realize popularization and application.
Summary of the invention
The utility model is: use micro computer that noise, power consumption and the ore pulp flow regime of ball mill are analyzed, whether judge interior material level height of ball mill and pulp density suitable, automatically regulate feeding coal and confluent, allow ball mill be operated in best grinding state, realize the high efficiency running.Replace expensive concentration sensor with simple dressing probe, promptly reduced cost, reduced fault rate again, thereby realized energy-conservation, stable, volume increase function.
The technical scheme that its technical problem that solves the utility model adopts is: the Weight acquisition device of installing on the flow collection device of installing on the power consumption collector of installing on the noise gathering device that microcomputer host is installed with the ball mill side respectively, the ball mill motor, the dressing densimeter that the ball mill discharging opening is installed, the supply line and electric control valve, the feeding belt and the vibrator of linear speed collector, material inlet link to each other, process optimization is calculated and controls, and makes ball mill be operated in optimum state.
The dressing densimeter: the direction of rotation with ball mill when ore pulp flows out is offset, bias size and pulp density are directly proportional, the dense more side-play amount of ore pulp is big more, the rare more side-play amount of ore pulp is more little, and we are according to the conductive characteristic of ore pulp, with evenly vertical being fixed on the densimeter main body of several metal probes, form the dressing densimeter, be fixed on the ball mill discharging opening, all probes that touches ore pulp are equal to ground connection, and the ground state of our measuring probe can be learnt the side-play amount (being corresponding concentration value) of ore pulp.With probe over against the center of ball mill discharging opening fixing dressing densimeter (position, the left and right sides), regulating each probe respectively, just to leave 1 centimetre of ball mill discharging opening barrel fixing, this step is the structure of dressing densimeter and realizes principle.
Optimum concentration value: the ball mill of different bores, the side-play amount of corresponding concentration are also different, measure and regulate with the concentration kettle earlier, obtain suitable pulp density, with the value unit of dressing densimeter (%) this moment, are set at the normal concentration value.
Optimum filling amount: the noise height of ball mill and the loading relation of being inversely proportional in the mill, the many more noises of loading are low more, and the few more noise of loading is high more.And each ball mill optimum filling amount and noise fix, analytical test allows the loading of ball mill reach best at first repeatedly, with the level of noise record unit (decibel) of this moment, as the noise setting value, this step realizes the collection of ball mill optimum filling amount (noise).
Permanent noise: microcomputer host is collected the signal of noise gathering device, compare with the setting level of noise, be higher than setting value as currency and then increase the setting feeding coal automatically, be lower than setting value as currency and then reduce the setting feeding coal automatically, ball mill is always worked in set level of noise (optimum filling amount) state, concrete with the realization of ' bluring ' control mode, this step realizes permanent noise (permanent loading) work.
Permanent feeding coal: microcomputer host is according to the signal of weigh collector and the linear speed collector installed on the feeding belt, calculate and current actual feeding coal, unit ' ton/hour ', set feeding coal in (permanent loading) relatively, as strengthening the dispenser power of shaking automatically,, finally make actual feeding coal constant for setting feeding coal as reducing the dispenser power of shaking automatically greater than setting then micro computer less than setting then micro computer, realize with pid control mode that specifically this step realizes constant feeding.
Permanent concentration: the microcomputer host per second is measured the value and the record of a dressing densimeter, enough then preceding 15 times record is added up divided by 15 for 15 times, obtains 15 times mean value (being valid density), and effectively the fluctuation of filtering ore pulp is disturbed, and improves the degree of accuracy.Compare with normal concentration, as rarer than normal concentration, then micro computer reduces the setting confluent automatically, and as denseer than normal concentration, then micro computer increases the setting confluent automatically, makes pulp density remain normal concentration, and this step realization pulp density is regulated automatically.
Permanent confluent: the flow value that microcomputer host provides according to the flow collection device, unit ' cubic meters/hour ', set confluent in (permanent concentration) relatively, as then automatically motor-driven valve being left greatly less than setting confluent, as then automatically motor-driven valve being turned down greater than setting confluent, making present flow rate is the actual needs confluent, specifically realizes that with pid control mode this step realizes constant feedwater.
When concentration was rare partially, ball mill efficiency was on the low side, power consumption is higher gradually; During the concentration overrich,, almost there are not fragmentation, grainding capacity though the ball mill power consumption reduces, efficient is minimum, and when loading was not enough, noise increased steel ball, the liner plate loss becomes big, when loading is too much, steel ball loses projectile motion, and operating efficiency is low, seriously can cause full mill (tripe expands), this also is the existing drawback of manually-operated, this function realizes permanent loading, normal concentration operation, and ball mill is in the best concentration of grinding all the time, reaches efficient, low consumption, energy-conservation.
The beneficial effects of the utility model are: reduce cost, simplify installation, improve operability, water saving, economize on electricity, saving finished product ' steel ball, liner plate ' loss, finally reach the effect of energy-conservation, stable yields, volume increase.
