Method and device for stable control of scraper reclaiming flow in circular coal yard stacker-reclaimer

Abstract

The invention discloses a round coal field stacker-reclaimer scraper plate reclaiming flow stable control method and device. The method comprises the steps of acquiring the current of a scraper platemotor and the coal field stacking angle; calculating the current instant reclaiming flow of a stacker-reclaimer through a preset functional relationship according to the current value of the scraper plate motor and the coal field stacking angle, wherein the preset functional relationship is used for representing the corresponding relation of the instant reclaiming flow, the coal field stacking angle and the scraper plate current; and conducting feedback regulation on the current instant reclaiming flow according to the target instant reclaiming flow. According to the round coal field stacker-reclaimer scraper plate reclaiming flow stable control method and device, the target instant reclaiming flow is automatically calculated and regulated according to variation of the coal field stackingangle and the motor current to approach the actual instant reclaiming flow, the instant reclaiming flow of the stacker-reclaimer can be stabilized, and the operation efficiency can be improved.

Description

technical field [0001] The invention relates to the field of material conveying systems and equipment intelligence, in particular to a method and device for stabilizing the flow rate of a scraper of a stacker-reclaimer in a circular stockyard. Background technique [0002] In the circular material yard, the cross-section of the material is a conical shape. During the reclaiming operation, the material reclaiming arm is close to the inner side of the conical surface of the material, and the material is scraped by the scraper into the reclaiming hopper in the center of the material yard, and passed through The conveyor belt is transported out of the material yard. The feeding depth of the scraper directly affects the instantaneous flow rate of the material. In order to ensure the stability of the material flow, the operator controls the descending depth of the scraper through the button start and stop, and the scraper can be increased or decreased through video monitoring. The...

Problems solved by technology

If working for a long time leads to physical fatigue and lack of concentration or the operator is inexperienced, it will lead to inaccurate operation, which will make the amount of material taken vary from time to time, which will affect the stability and efficiency of the operation.
