Embodiment 1

[0104] Taking a vibrating screen for coal 6mm screening as an example, when the vibrating screen in the model system runs stably, select any time to collect the working condition parameters and material parameters of the vibrating screen. details as follows:

[0105] For the operating parameters of the vibrating screen, (i) firstly 0 The stress and strain, acceleration, rotational speed and temperature at time and the acceleration information of the screen surface are collected.

[0106] (ii) will t 0 The stress-strain, acceleration, speed and temperature, and the acceleration information of the screen surface corresponding to the time are collected. The current stress-strain, acceleration, speed and temperature of the screen machine, and the acceleration information of the screen surface are compared with the data interval of the previously established cloud database to determine whether out of range ±5%.

[0107] (iii) If it exceeds the range of ±5%, it means that there m...

Abstract

The invention relates to an industrial screening effect dynamic evaluation method based on digital twinning, belongs to the technical field of mineral screening, and solves the problem that the industrial screening effect cannot be dynamically observed online and evaluated in real time in the prior art. The evaluation method comprises the steps that 1, screening machine structure parameters, material parameters, particle swarm component parameters, screening process load parameters and equipment operation surrounding environment information are collected; 2, establishing a three-dimensional structure model of the screening machine; 3, establishing a digital twinborn simulation model of the screening machine; 4, correcting the digital twinborn simulation model of the screening machine; 5, building a cloud database based on the corrected digital twinborn simulation model of the screening machine, and obtaining the real-time operation state of the equipment through the terminal equipment; and 6, based on the obtained real-time running state of the equipment, evaluating the screening effect in real time. The working condition parameters of the screening machine in the screening process can be collected in real time, and the structure, the operation state, fault early warning and the screening result of the screening machine can be detected in real time.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a method for dynamic evaluation of industrial screening effects based on digital twins. Background technique [0002] Sieving is a separation technology that separates materials with different particle sizes through the sieve holes and divides them into materials with different particle size ranges. Industrial screening refers to the large-scale screening of continuous production materials in the process of mining and processing in factories or mines, as a key link in its industrial production process. [0003] The traditional screening effect evaluation mainly focuses on static sampling to evaluate the screening effect for the materials that are subjected to a single screening operation. For industrial screening, in the continuous production process, the traditional screening effect evaluation system can only randomly sample and evaluate, and cannot realize real-time online a...
