Research On Dust Removal Control System Of Coal Transportation In Shengli East No.2 Mine

This paper is aimed at the status of dust pollution at each dust source in the process of reloading and transporting solid materials in Shengli No.2 Open-pit Coal Mine.Combined with the actual working conditions at the site,the investigation and comparison of many places have been carried out.Finally,the bag filter is selected as the dust removal mechanical component of the dust removal system.In the period of infrastructure construction,the original dust removal equipment was not considered to be comprehensive and was operated on a stand-alone basis,and the system was not inefficient.This time,the dust removal system was designed using an automatic control system.The PLC of the coal mine dust removal front was selected as the controller.The PLC was used as the brain of the control system to receive and send data information in real time through relays or transmitters to monitor and control the operation of the entire system.The system is automatically operated,which greatly reduces the number of on-site operators and reduces the probability of mechanical and personal injury caused by human error,ensuring efficient and accurate operation of the equipment.This paper has carried out a comprehensive design study on the hardware and software of the dust control system.The hardware part includes the design of the main loop of the control system,the principle of the control loop and the wiring design.The software part includes the selection and selection of the controller,the design of the I/O point,the selection of the communication mode,and the design of the control program.Finally,a complete dust control system is formed to centrally control,automatically detect,automatically vibrate and clean,process interlock and remote control the dust source equipment.After the installation of the system equipment,the single-machine no-load test run,single-machine heavy-load test run,online no-load test run,online heavy-duty test run and other tests,continuously find problems,solve problems continuously,and finally make the dust control system reach long-term stable operation.status.The software and hardware design of the dust control system realizes the functions required by the design to ensure efficient,safe and stable operation of the coal removal and dust removal system.The paper has 25 pictures,9 tables and 54 references.
