The present invention will be described in detail with reference to examples, but the present invention is not limited to the following examples.
The PLC controller 8 adopted by the utility model is Siemens S7-200 series.
The existing dry anaerobic fermentation system comprises a straw feeding port 1, a straw conveyor 2, a straw crusher 3, a straw crushed material precipitator 4, a fan 5, a conveying belt 6 and a material collector 7. The dry anaerobic fermentation raw material is straws, the straws are fed into a straw conveyor 2 through a straw feeding hole 1, and the straws are fed into a straw pulverizer 3 by the straw conveyor 2; the straw pulverizer 3 pulverizes the straws, and crushed materials fall onto a conveying belt 6 and are conveyed into a material collector 7; the sediment dirt of straw grinder 3 carries out precipitation separation through crushed straw material precipitator 4, and the lateral part of crushed straw material precipitator 4 is equipped with fan 5, gets into the sediment dirt flow in crushed straw material precipitator 4 through fan control. Aiming at the problems of single automatic program and poor control coordination capability of each process, the utility model provides a dry anaerobic fermentation feeding system based on PLC control.
In order to achieve the purpose, the technical scheme adopted by the utility model is a PLC (programmable logic controller) control dry anaerobic fermentation feeding system, which comprises a straw conveyor controller 21, a straw crushing compensation cylinder 31, a temperature and humidity sensor 32, a weight sensor 71 and a PLC 8; the straw conveyor controller 21 is arranged at the inlet of the straw conveyor 2, the crushed straw compensating cylinder 31 is arranged at the top of the straw pulverizer 3, and the temperature and humidity sensor 32 is arranged inside the straw pulverizer 3; the weight sensor 71 is mounted at the bottom of the collector 7.
