What is the hot mix plant control system?

Programmable controller as the core of hot mix plant control system, to complete the boot of asphalt equipment, ingredients and various working during transport. whole equipment control system composed by feeding, ingredients and transportation each of these three parts independently of each other. Each section has two operating modes, manual and automatic. IPC and touch screen have the function, that complete the main process parameters, workflow display and alarm output of the equipment. IPC also has these function that production data automatic archiving, production statistics queries, improve of the report output. to meet the job requirements of asphalt mixing equipment, according to the requirements the system is configured automatic and manual intervention in two ways, for operators provides a convenient in the commissioning, production preparation and different ways of working, such as normal production.The manual type: through the console buttons the poerator complete manually production or troubleshooting emergency maintenance .

The automatic type: PLC as the core, avariety of sensor, limit switches, and each loop feedback signal as collected objects, through the PLC's digital output module control device startup,ingredients mixing transportation and other automated production process.
Oblique trolley adopt inverter control, use rotary encoder to variable speed and positioning control, make the trolleys run more smoothly. And has overrun limit switch, so that the trolleys running more secure.
baghouse dust collector adopt pulse cleaning dust, circuit board to control the pulse valve job to make bag cleaning. For the baghouse inlet temperature set a protection device and cold wind door, the opened size of cold wind door decided by the baghouse inlet temperature, to adjust the baghouse inlet temperature, and to ensure continuous production. another ,the baghouse dust collector set a baghouse over-temperature extinguish fire device, that can be set the high temperature limit value according to the baghouse use temperature, when the baghouse inlet temperature exceeds the high temperature limit value, the burner is automatically turned off to protect the bag.aggergate drying system adopted Liaoyuan group(www.lyroad.cn) burner, equipt liaoyuan group muffler, low noise, and improved fuel lines, automatic cycle circuit before ignition, automatic purge line after the cease-fire, the direct use of heavy firing, user-friendly. hot aggregate temperature control have manual and automatic two ways, when ignition use manual control, when the hot aggregate temperature stability switching to automatic control, in automatic mode, the temperature control precision high stability, without operator intervention, convenient operation.
At the top of the three reservoirs silo installed level meter, when the storage bin is full, then the audible alarm. on the powder silo wall installed vibrator warehouse wall, when detected powder stick stuck atop vibration vibrator can take it down.
Five hot silo and bunker adopted continuous level meter, so that the operator can more accurately understand the thermal material and power reserves, in order to adjust the feed rate.In the fine cold aggregate positions with a broken material detection switch, for cold aggregate timely detection alarm and timely processing. At the site has an cold aggregate emergency stop button. In the operating table, set the "emergency stop" button, the occurrence of unforeseen circumstances, can press this button, the entire equipment downtime.
