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 discloses an industrial screening effect dynamic evaluation system and evaluation method, 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 system comprises a digital twinborn simulation unit and a screening effect real-time evaluation unit which are connected with each other, the digital twinborn simulation unit is used for simulating an actual industrial screening process and comparing obtained virtual test data with actual industrial screening data so as to reflect the actual industrial screening process; and the screening effect real-time evaluation unit is used for evaluating the screening efficiency, the processing capacity, the mismatch content, the upper limit rate and the lower limit rate. 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 dynamic evaluation system and evaluation method for industrial screening effects. 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] Digital twin refers to the full use of physical model, sensor update, operation history and other data to build a simulation process and complete the mapping in the virtual space to reflect the full life cycle process of the corresponding physical equipment. [0004] The traditional screening effect evaluation mainly focuses on static sampling to evaluate the screening effe...
