Belt Conveyor

For the conveyor belt, variable material flow influences the energy efficiency of the speed control technology significantly. The fluctuation of material flow on the conveyor belt will lead to the detrimental vibrations on both the belt and the conveyor while the conveyor works at certain speeds. In order to improve the model inaccuracy caused by the uniform bulk material flow assumption in the current conveyor belt model, the paper establishes a high-precision dynamic model that can consider speed control of a conveyor belt under non-uniform bulk material transportation. In this dynamic model, a non-uniform bulk material distribution model is firstly proposed based on laser scanning technology. Then, a high-precision longitudinal dynamic model is proposed to investigate the dynamic behavior of a belt conveyor. Considering the micro-units of actual load on a conveyor belt, it can well describe the transient state of the conveyor belt. These models can be used to determine the optimal speed for safety and energy conservation in operation. Experimental results are used to validate the proposed dynamic model for analyzing belt mechanical behavior under non-uniform bulk material distribution on the belt. The results show that the proposed models can be used for optimizing the operating procedures of belt conveyor systems.

Belt conveyors are the major equipments for bulk material transportation.This paper analyses the static and dynamic behaviours of the belt, and establishes the dynamic elastic modulus. By analyzing the characteristics of the Kelvin and Maxwell viscoelastic model, the former is selected as the conveyor belt model as it can more realistically reflect the mechanical characteristics of the conveyor system. This paper introduces the development of the belt conveyor, and analyzes the current research situation at home and abroad.

Currently, the widespread use of tubular belt conveyors is constrained by insufficient justification of the conveyor parameters. In the work, on the basis of the theory of the limiting equilibrium state of bulk load, equations of equilibrium of load on the belt of an inclined tubular conveyor are obtained. It is assumed that the belt was a rigid cylinder filled with bulk material in extreme equilibrium. Based on the obtained equilibrium equation, the analytical dependences of the limiting angle of inclination of the belt conveyor with a tubular belt on the degree of unfilling with the bulk load of the belt and the properties of the bulk load are found. From the analysis of these dependencies it follows that the limiting angle of inclination of the tubular belt conveyor depends on the angle of internal friction of the transported load, the angle of friction of the load on the conveyor belt, the angle of unfilling of the belt with load and does not depend on the radius of the conveyor belt.

Belt conveyor is widely used in a variety of automated production lines and bulk material transportation is one of the most important applications. In order to improve the accuracy of the belt conveyors, it is need not only to strictly control the production crafts, more importantly, to improve the rationality of the structure and design level. Running deviation and adjusting deviation problem are important issues to be considered in a belt conveyor design process. In this study, the 3D synchronous technology of Solid Edge ST4 will be applied in the design of the belt conveyor to design a new type of anti-deviation structure. In the design process, we combine the synchronous technology with modular technology and top-down assembly modeling techniques to confirm the subject and adjust deviation. The key is the application of synchronous technology in 3D design and the new structure in Running Deviation and Adjusting Deviation. It turned out that the application of above technology can reduce design errors and avoids the repeated design, thus greatly improving the efficiency of the engineer's design. Meanwhile, the study of running deviation can make the structure of adjusting deviation come true.

A new design of a belt conveyor has been proposed with the possibility of changing the cross section of a conveyor belt depending on the flow of the bulk material being transported. A method for determining the load on the mechanism of rotation of the pressure levers is presented. The calculation of the value of the equivalent load on the screed, taking into account crimping are given. This allows you to determine the internal diameter and select the parameters of the trapezoidal thread of the screed, calculate the resistance moments in screw pairs and adopt the appropriate size of the gearmotor.

Abstract The consideration of potential energy stored in a system is paramount to carry on safe maintenance operations of mechanical system. In particular, this paper concentrates on the elastic energy accumulation occurring in a belt conveyor system ensuing a seizure of one of the pulleys owing to, for example, dirt and spilled bulk material accumulation in the belt inlet zone. The hazard of considering the system completely discharged just because the electrical supply cut off and the effect of such an energy storage are investigated by means of a lumped mass dynamic mathematical model. It allows time variable operating conditions to be considered, as well as starting and stopping phases transients. Standard maintenance operations are simulated, and the effect of stored energy sudden release investigated.

Belt conveyor system for bulk material in large plants usually needs amounts of transfer station, which are one of most important dust generation areas. The dust generation mechanism of transfer station is that bulk material dropping down from high site causes air flow and small particle material move with air. The skirtboard of transfer station can restrain dust to some extent through airproofing its flow. Gas-solid flow in transfer station is simulated with Computational Fluid Dynamics (CFD) method in this paper. Based on the simulation results of traditional rectangular skirtboard, an optimized skirtboard is proposed. Contrast of two plans’ simulation results indicates that the new one can restrain dust obviously, which is significant for material saving and environment protecting.
