Optimization Of Control System Of Vertical Garbage Compression Recycling Station

As a kind of environmental sanitation mechanical equipment with a wide range of applications,the vertical garbage compression recycling station plays an important role in the compression treatment of domestic garbage.In view of the low efficiency of the hydraulic system of the vertical garbage compression station,the large amount of heat generation,and the low level of automation of the control system,the hydraulic system and control system of the garbage compression station need to be optimized and improved.The specific research content is as follows:Aiming at the problems of low efficiency of the hydraulic system and insufficient working reliability,the model of garbage compression is analyzed,and the various circuits of the hydraulic system of the garbage compression station are optimized.First,establish a surface model of the garbage to pave the way for the simulation of the hydraulic system;second,compare the characteristics of each system circuit before and after the optimization of the hydraulic system,and analyze that the optimized system schematic diagram is more in line with actual needs;third,by simulating the hydraulic pressure of each circuit The change curve of cylinder pressure,flow,speed and stroke verifies the feasibility of hydraulic system optimization.Aiming at the problems of large power loss in hydraulic system and high hydraulic oil temperature,the power loss method and thermodynamic modeling are used to calculate the thermal equilibrium temperature.Firstly,using the first law of thermodynamics,it is concluded that the difference in pressure at the inlet and outlet ports of valves,pumps,pipelines,etc.is the main reason for system heat generation and oil temperature rise;secondly,heat generation is performed on different circuits of the vertical garbage compression station And heat dissipation analysis,and use the power loss method to estimate the heat balance temperature of the garbage compression station;third,establish the thermodynamic model of the hydraulic system,and after comparison,the heat balance temperature obtained by the simulation is basically consistent with the heat balance temperature estimated by the power loss method.Aiming at the problem that the heat balance temperature of the hydraulic system is too high,measures to improve heat dissipation are proposed.By using methods such as coating the surface with a graphene filler coating,increasing the area of the fuel tank,and increasing the radiator,the temperature when the system reaches thermal equilibrium is about 18.7°C lower than the original thermal equilibrium temperature.When the ambient temperature is35°C(the average indoor summer temperature in the Central Plains),the equilibrium temperature of the oil in the fuel tank is close to 64.7°C,which meets the working requirements of the garbage compression station.In view of the low level of automation of the control system,the recycle bin control system is optimized.Firstly,analyze the operation process of different garbage treatment stages,determine the PLC control plan and the goals to be achieved;second,select the main components of the PLC and allocate I/O ports,draw out the PLC control circuit diagram,and build the experimental bench Provide theoretical basis;third,draw manual and automatic control programs of PLC ladder diagram,design human-computer interaction interface,and realize data sharing through PLC and human-computer interface communication;fourth,build a garbage compression station control system experimental platform,Debug the manual and semi-automatic systems to prove that the control system of the garbage compression station meets the requirements set by the program.
