The Gypsum board production line adopts the advanced DCS monitor system. The whole process divided into five parts, distribution shaping, central control, automatic board-enter, Auto board-exit and drying kiln temperature control. They are monitored by DCS monitor system all the time.According to the production flow, the gypsum board production line DCS monitor system can be divided into five parts: preparation shaping machine, centralized control, auto board-enter, auto board-exit and kiln temperature Control.Preparation shaping machine: gypsum powder screw conveyer, thick pastes pump, vesicant metering pumps, feeding screw conveyer, slurry mixer, forming station mixer, platform shaking machine and ring belt forming machine. By adopting the computer control system, the gypsum powder, foaming agent and slurry can be mixed in a scientific way. The process is high precise, easy to operate, energy saving.Centralized control system: the general control can deal with the data acquisition and processing, at the same time; monitor the shaping process and drying process. With the support of powerful database, together with humidity and temperature also other recorded parameter, we can materialize scientific management. The computer interface is friendly, easy to operate; all parameters can be known at the first glance. The preparation, shaping, drying process is highly automatic, even the beginner can operate it.Auto board-enter system: auto board cutter, belt conveyor, roller, board turnover machine, kiln enter distributor, faster board-enter and other equipment, through PLC auto control, the process of cutter, speed-up, kiln enter of gypsum board is finished. Automatic Finished board system: It includes Board-exit from dryer, layer-distributor, horizontal belt conveyor, roller, cutter and stacking machine. All of them are done by central control system through sensor, PLC, touch screen and control panels. Cutting, taping and stacking are finished automatically. The system has the functional such as Data amendment, productivity inquiry, and real time event alarm and status inquiry. Drive, temperature control, and hot air cycling system: This system is controlled through remote meter and humidity sensor. Heating conveyor and hot air cycling are control by computer. Using inverter makes the drying accurate and saving energy. Two features of the DCS monitor system are that it can provide centralized management and distributed control. The controlling and data gathering are automatic finished by branch system. The center control can monitor the whole process and record data, thus decrease the frequency of breaking down of system.
