A control method for a disc feeder anti-jamming control system

Abstract

The invention discloses a disc feeder anti-jamming control system and a control method thereof. Two sets of motors are controlled by setting two sets of frequency conversion control equipment and cooperating with a PLC controller to replace a traditional disc feeder with a frequency converter. The method can effectively complete the functions of start, stop, early warning and online adjustment of working speed of the control system, realize the synchronization of the speed of the batching disc feeder and the speed of the belt conveyor, and the running direction is consistent, and the running speed of the frequency converter and the weighing sensor realize PID Closed-loop automatic adjustment to complete precise batching; at the same time, when the disc feeder is jammed, the disc feeder is automatically reversible to discharge foreign objects, and during the process of removing foreign objects, the running speed and direction of the belt conveyor will not be affected , and after the foreign matter is automatically discharged, the disc feeder can automatically delay the forward start to maintain the original normal working state, so as to avoid the occurrence of the stop of the disc inverter due to the blocking of the discharge port due to foreign matter.

Description

technical field [0001] The invention belongs to the technical field of electric control of material conveying equipment such as mining, sintering, and ironmaking production, and relates to a disc feeder anti-jamming control system and a control method thereof. Background technique [0002] Among the traditional material transmission equipment, such as: volumetric batching equipment-quantitative disc feeder, also known as batching disc. Its working function is to properly mix various sintering raw materials according to the process requirements before the materials are evenly mixed. During the production process, according to the test results of the finished sintered ore (such as powder content, drum value, etc.) , to adjust the proportioning value appropriately to increase the rate of qualified products. [0003] At present, the electric control system of the domestic batching disc feeder generally uses an AC frequency converter to drive two three-phase AC asynchronous moto...
