Analysis And Optimization Of The Influence Of Different Materials And Design Parameters On Transfer Station

Belt conveyor is favored by coal mine and other bulk material transportation field because of its characteristics of long distance and large volume.Transfer station is the key equipment for belt conveyor to transport bulk materials.With the progress of science and technology,the belt conveyor is developing towards the direction of intelligence,low pollution and high efficiency,so the reliability and transmission performance of the transfer station are put forward higher requirements.In order to improve the reliability and transport performance of transfer station,the design of transfer station structure is the key to solve the problem.In this paper,using the discrete element software simulation analysis was carried out on the transfer station,using the method of single factor experiment,the types and characteristics,from the material transfer station structure parameters,transshipment,respectively study material particle size,viscosity and conveyor belt speed on the impact of the head funnel effect,material viscosity,conveyor belt speed and the Angle of cross the influence of the mass flow rate,The influence law of material granularity,viscosity,conveyor belt speed and four-way Angle on material velocity of transfer station is studied,and the influence law of different materials on transfer station is compared.The results show that with the increase of the material size,the force on the head funnel increases,the material velocity at the outlet of the transfer station decreases,and the partial velocity in the X,Y and Z directions also decreases.Under the condition of the same material size,coke coal has the largest impact force on the head funnel,followed by anthracite and lignite.The lignite exported from the transfer station has the largest speed,followed by anthracite and coke coal.With the increase of the material viscosity,the force on the head funnel decreases,the average mass flow rate decreases,the material velocity at the transfer station outlet decreases,and the partial velocity in the X,Y and Z directions also decreases.Under the same condition of material viscosity,the impact force of coke coal on the head funnel is the largest,followed by anthracite,lignite is the smallest,lignite mass flow rate is the largest,anthracite is the second,coke coal is the smallest,lignite exit speed of transfer station is the largest,anthracite is the second,coke coal is the smallest.With the increase of belt speed,the force on the head funnel increases,the average mass flow increases first and then decreases,and the material velocity at the outlet of the transfer station decreases,and the partial velocity in X,Y and Z directions also shows a decreasing trend.With the increase of the four-way Angle,the average mass flow rate decreases,the exit material velocity,X direction velocity and Y direction velocity decrease,and Z direction velocity increases.First station to the original structure was improved,using a single variable method analysis the improved transfer station conveyor belt speed,cross Angle,the influence of the export of material transfer station exit speed,using the orthogonal experimental method to the three structure parameters such as probability combination analysis,and the simulation calculation,using poor method and matrix method to analyze the simulation results,the influence weight of each factor and the optimal combination model are obtained.Finally,based on the optimal combination model,the improved forward transfer station was set as the control group,and the influence of the improved forward transfer station on the material velocity at the exit was compared and analyzed.
