Material blocking prevention control system of disc feeder and control method of material blocking prevention control system

Abstract

The invention discloses a material blocking prevention control system of a disc feeder and a control method of the material blocking prevention control system. According to the material blocking prevention control system of the disc feeder and the control method of the material blocking prevention control system, two sets of frequency conversion control equipment are arranged and are matched with a PLC (Programmable Logic Controller) to replace a control mode that one frequency converter of a traditional disc feeder controls two motors, so that the functions of starting, stopping, early warning, online regulation of a working rotating speed and the like of the control system are effectively completed; the rotating speed of the batching disc feeder and the rotating speed of a belt conveyor are synchronous and consistent in running direction, PID closed-loop automatic adjustment is achieved through the running rotating speed of a frequency converter and a weighing sensor, and precise batching is completed; and meanwhile, when the disc feeder is stuck, the disc feeder is driven to automatically and reversibly operate to discharge foreign matters, the operation rotating speed and direction of the belt conveyor are not affected in the foreign matter discharging process, after the foreign matters are automatically discharged, the disc feeder can automatically delay forward starting to keep the original normal working state, so that a discharge port is prevented from being blocked by the foreign matters, and shutdown caused by protection action of the disc frequency converter is avoided.

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...
