High-stability driving control method and system for continuous granulation reaction kettle

Abstract

The invention provides a high-stability driving control method and system for a continuous granulation reaction kettle, and the method comprises the steps: presetting that the continuous granulation reaction kettle is provided with two driving circuits, namely a first driving circuit and a second driving circuit, and defaulting that the first driving circuit drives and controls the continuous granulation reaction kettle to rotate; synchronizing the control parameters of the first driving circuit to the second driving circuit in real time; a monitoring module monitors the working state of the first driving circuit in real time; and when the monitoring module monitors that the working state of the first driving circuit is abnormal, the second driving circuit replaces the first driving circuit to drive and control the continuous granulation reaction kettle to rotate according to synchronous control parameters. Through the switching of the main and standby driving circuits, the condition of accidental interruption of the continuous granulation reaction kettle is effectively prevented, the stable operation of the continuous granulation reaction kettle is ensured, and meanwhile, the potential safety hazard is avoided.

Description

technical field [0001] The invention relates to the technical field of automation control, in particular to a high-stability drive control method and system for a continuous granulation reaction kettle. Background technique [0002] Lithium batteries are batteries that use lithium metal and lithium alloy as negative electrode materials and use a non-aqueous electrolytic solution. Due to the very unstable chemical properties of lithium metal, the reactor for processing lithium batteries needs to meet very high requirements. The existing continuous granulation reaction kettle generally includes a rotary drum, a heater, a driving motor and a heating furnace body. The heating furnace body is composed of upper and lower parts. The rotary drum and the heater are arranged inside the heating furnace body. In the production process, the driving motor drives the rotary drum to rotate, so that the lithium metal material in the rotary drum flows forward, and at the same time, the heate...

Problems solved by technology

Since the lithium metal material reacts during the rotation and feeding of the rotary drum, the rotary drum needs to be kept in a continuous state of rotation. Once the drive motor or the drive circuit that provides the power to the drive motor fails, the rotary drum will not be able to rotate, which will lead to The particle reaction is interrupted, and the lithium metal material retained in the rotary drum will also pose a safety hazard due to local continuous heating.
