Изобретение относитс  к автоматическому управлению работой сгустител  и может примен тьс  в галургической промышленности.This invention relates to the automatic control of thickener operation and can be applied in the halurgical industry.

Известен способ автоматического управлени  работой сгустител  путем регулировани  расхода разгружаемого сгущеиного продукта и коагул }1та в зависнмости от высоты осветленной зоны, так II от концентрации твердых частиц в разгружаемой пульне.There is a known method of automatically controlling the operation of the thickener by adjusting the flow rate of the discharged condensed product and coagulum} 1 mt depending on the height of the clarified zone, and II on the concentration of solid particles in the unloaded pulp.

Предлагаемый снособ отличаетс  от известного тем, что расход сгущенного продукта и подачу коагул нта регулируют в зависимости от высоты зоны стесненного уплотнени . Это упрощает схемное регнеиие и повышает надежиость систем автоматического управлени  сгустителем.The proposed method is different from that known for the fact that the flow rate of the condensed product and the flow of coagulum are regulated depending on the height of the zone of the constrained compaction. This simplifies circuit regeneration and increases the reliability of automatic control systems for the thickener.

На чертеже изображена блок-схема системы автоматического уиравлени .The drawing shows a block diagram of an automatic steering system.

Способ заключаетс  в следующем.The method is as follows.

Сигнал о текущем зиачепии высоты зоны стесненного уплотнени  в сгустителе 1 с измерительного устройства 2 подают на регул тор 2. Сюда же подают сигнал с задатчика 4. Регулирующее воздействие с регул тора 3 подают на регулирующий орган 5, нзмен ющий расход сгущенного продукта.The signal of the current height of the zone of constrained compaction in the thickener 1 from the measuring device 2 is sent to the regulator 2. The same signal is supplied from the setting device 4. The regulating action from the regulator 3 is fed to the regulator 5, which replaces the flow of the condensed product.

Сигпал о текущем значении высоты зоны стесненного уплотнени  с измерительного устройства 2 подают также на регул тор 6, в котором оп сравниваетс  с сигналом, подаваемым с задатчика 7. Регулирующее воздействие с регул тора б подают на регулирующий оргаи 8, измен ющий расход коагул нта.The sigpal about the current value of the height of the zone of constrained compaction from the measuring device 2 is also supplied to the regulator 6, in which it is compared with the signal supplied from the setting device 7. The regulating action from the regulator b is applied to the regulating body 8, which changes the coagulant flow rate.

Предмет изобретени Subject invention

Способ автоматического управлени  работой сгустител  путем регулировани  расхода сгущениого продукта и подачи коагул нта, отличающийс  тем, что, с целью упрощени  схемного решени  и иовышени  надежностн систем автоматического управлени , расход сгущенного продукта и подачу коагул нта регулируют в зависимости от высоты зоны стесненного уплотнени .A method for automatically controlling the operation of the thickener by controlling the flow rate of the thickened product and supplying the coagulant, characterized in that, in order to simplify the circuit design and increase the reliability of the automatic control systems, the flow rate of the condensed product and the flow of the coagulum are adjusted depending on the height of the constrained compaction zone.
