System for resin transfer redundancy automatic control in treatment process of leaching solution

Abstract

The invention belongs to the technical field of resin transfer automatic control in the treatment process of uranium ore leaching solution, and specifically relates to a system for resin transfer redundancy automatic control in the treatment process of leaching solution. The various operation states of valves and pumps and the feedback signals of a level gauge and a pressure transmitter in the process of resin transfer are uploaded to a PLC through a DI input module and an AI input module. After the PLC carries out internal data processing and logic programming operation, a DO output module outputs a control command to control the start and stop of the valves and the pumps. The PLC is connected to a switch through a communication module. An industrial personal computer is connected to the switch through a network cable. In the process of resin transfer, the various operation states of the valves and the pumps and the real-time measurement data of the level gauge and the pressure transmitter are integrated and displayed on the industrial personal computer. In the process of resin transfer, various process data is set through the interface of the industrial personal computer. The problems in the prior art, namely, resin transfer is semi-automatic, the adoption of a single controller results in low reliability, and production may be interrupted, can be solved.

Description

technical field [0001] The invention belongs to the technical field of automatic control of resin transfer in the uranium ore leachate treatment process, and in particular relates to a redundant automatic control system for resin transfer in the leachate process. Background technique [0002] At present, there are mainly two operating methods for resin transfer in the process of uranium ore leachate treatment. The first is that each valve device is all manually controlled, and it needs to be manually controlled to start and stop. The idea and control system of this control method are relatively simple, but the disadvantage is that the operation of the equipment is complicated and cumbersome, and the labor intensity of the workers is high. Once the intermediate equipment fails or is misoperated, the process will be confused and delayed, and the practicability is poor. The second is that the start and stop of equipment in the resin transfer process is controlled by PLC. PLC c...
