(54) DEVICE OF CONTROL OF LOADING GROUP OF LUMYNESCENTNB1X SEPARATORS

one

The invention relates to the enrichment of field minerals, namely the management of sorting devices, and can be used to control the loading of a group of luminescent separators.

A device is known for controlling the loading of a group of luminescent separators, comprising a setpoint gauge, connected to the corresponding vibrating feeders of the feed bin and a quality analyzer, and a control cycle forming unit 1.

A disadvantage of the known device is the low quality of sorting due to the impossibility of evenly distributing the ore to the group of separators under the conditions of oscillation of the initial feed.

The purpose of the invention is to increase the quality of sorting.

The goal is achieved by the fact that the device for controlling the loading of a group of luminescent separators — containing, capacity controllers, connected to the corresponding vibrating feeders of the feeding bunker and an analyzer of the quality of work, and a control cycle shaping unit — are equipped with a control unit

level, difference determining unit, performance determining unit, separator selection unit, separator state analyzer, unit of permissible level limits, unit of separation and level meter installed in the bunker and connected through the first inputs of level control units, determining differences, determining capacity and selecting the separator with the corresponding, Q and the unit controllers, while the second input of the level control unit is connected to the cycle shaping unit, the third one - with the unit master. imyh layer boundaries, and a second output connected to the second input of the determining proizvodi15 telnosti, wherein associated with the separators analyzer state separators and quality analyzer connected to respective inputs of separators selecting unit, and the setpoint difference is connected to the second input of the determining unit raz20

The drawing shows a diagram of a device for controlling the loading of a group of luminescent separators. A control unit for loading a group of luminescent separators containing performance adjusters 1, connected to the corresponding vibro feeders yi 2 of the feed hopper 3 and quality of work analyzer 4, and the control cycle forming unit 5 are equipped with a level control unit b, a difference determination unit 7, a performance determination unit 8, a unit 9 selection of separators, an analyzer 10 condition of separators by a setting device 11 for permissible level limits, a setting device 12 for difference and a measuring device for 13 level installed in the bunker 3 and Interconnected through the first inputs of the level control unit 6, the difference determination unit 7, the performance determination unit 8 and the separator selection unit 9 with the corresponding capacity setting devices 1, the second input of the level control unit 6 connected to the cycle shaping unit 5, the third to the setting unit 11 permissible level limits, and the second output is connected to the second input of the performance determining unit 8, and the separator state 10 and the quality analyzer 4 connected to the separators are connected to the corresponding the inputs of the block 9 of the selection of separators 14, and the unit 12 of the difference is connected to the second input of the block 7 for determining the differences. The device works as follows. The feed conveyor (not shown) supplies 3 ore to the hopper at a rate attributable to the performance of the preceding limits. Level gauge 13 controls the level of ore in the bunker 3, and block 6 controls the level in accordance with the cycle specified by block 5 periodically polls gauge 13 level. The signal from the level meter 13 goes to the level control unit 6, where it is compared with the permissible level boundaries according to the setting unit 11. If the ore level is within the acceptable limits, the signal from block 6 goes to block 7, where the difference between the levels of the current and previous measurement cycles is determined and in performance block 8. The level difference is compared with the value supplied from the difference setting unit 12. If it is less than the target, it is summed up with the subsequent differences until it reaches the target. When the specified difference is reached from the difference determination unit 7, the performance determination unit 8 receives a signal about the number of specified differences. In block 8, in accordance with the signals from blocks 6 and 7, a calculation is made of the change in productivity or the number of separators 14. With an increase in the level of ore in the bunker 3, the capacity of the separators 14 s will increase. POWER setters 1 and feeders 2 increase the schap proportional to the number of specified differences and the coefficient of effort, increasing from 1.0 with an average level of ore in the bunker to 2.0 when you reach any of the permissible limits. When the upper permissible limit is reached, which is caused by a sharp increase in the ore consumption in the bunker, all separators are turned on for maximum performance. If the level of ore in the hopper 3 decreases, the capacity of the separators 14 is reduced by a step proportional to the number of predetermined differences and the gain increasing from the average ore level to the allowable lower limit from 1.0 to 2.0. If the minimum performance is reached, and the ore level in the bunker 3 continues to drop, block 9 polls the condition analyzer 10 and the separator quality analyzer 4 and turns off the number of separators proportional to the number of specified differences multiplied by the gain factor. At the same time, according to signals from analyzers 4 and 10, the separators having the worst performance indicators are disconnected. When increasing the level above the permissible lower limit, the separators are included in the work, starting with the best. The quality of the operation of the separators is determined by the analyzer 4. The use of the device improves the quality of sorting by reducing the performance of the separators, keeping the ore cushion in front of them, turning off the separators with the lowest quality indicators. In addition, the device allows, under conditions of ore consumption for groups of separators, to ensure, on the one hand, ore processing by turning on all separators for maximum productivity, on the other hand, by reducing productivity, reducing the concentrate yield.
