Problems solved by technology

However, the existing research on the calculation method of the belt speed setting value of the belt conveyor focuses on the optimal matching of the belt speed setting value and the material transportation volume, but ignores the influence of the dynamic characteristics of the conveyor operation process.
The dynamic characteristics of the belt conveyor are complex during operation. Changes in belt speed and load will cause excessive fluctuations in belt tension, resulting in safety hazards such as broken belts and slipping.
Therefore, the currently commonly used calculation method for the belt speed setting value cannot guarantee the safe operation of the belt conveyor, and there is a great potential safety hazard

Abstract

The invention discloses a belt speed setting control method for a belt conveyor, which comprises the following steps of: establishing an energy consumption mathematical model of the belt conveyor, establishing a dynamic model of the belt conveyor, establishing a belt speed set value optimization problem, and solving the belt speed set value optimization problem, so as to obtain an optimal belt speed set value; The method is good in effect and convenient to implement, and the actual operation condition and dynamic characteristics of the belt conveyor can be reflected by arranging the energy consumption mathematical model and the dynamic model and arranging the bearing section, the return section and the tensioning device in the dynamic model; And a decision variable is set by establishing abelt speed set value dynamic optimization problem, so that the belt speed set value which enables the conveyor to achieve the optimal energy-saving effect can be obtained on the premise of ensuring the dynamic characteristics of the conveyor belt.

Description

technical field [0001] The invention relates to a calculation method of a belt speed setting value, which belongs to the field of belt conveyor control, in particular to a belt speed setting control method of a belt conveyor. Background technique [0002] Belt conveyor is a kind of high energy consumption equipment widely used in coal, chemical industry, wharf and other fields. At present, there is still a big gap between the average energy consumption efficiency of belt conveyors in my country and foreign advanced levels. Most of them operate in constant speed mode, which cannot be adaptively optimized according to changes in material transport volume, resulting in a large amount of energy waste. In terms of operation, according to the German standard DIN22101, properly adjusting the running belt speed according to the change of the conveyor material volume can produce a significant energy-saving effect. Therefore, many experts and scholars have carried out research on the...
