Abstract

The invention provides a coal screening system device based on big data and a screening method thereof. In the coal processing direction, the system device comprises a pre-screening device, a crushing device and a screening device which are sequentially connected through a conveying belt; the system device further comprises a detection device, a control device and a data processing device, the detection device comprises a particle size analyzer, and the control device receives a detection signal sent by the particle size analyzer and feeds back and controls the screening speed of the pre-screening device, the crushing particle size of the crushing device and the screening speed of the screening device; and the data processing device records the detection signal received by the control device and a control signal sent by the control device, and feeds back and adjusts control parameters of the control device. The particle size distribution of coal at each stage is detected, and the data processing device is combined with the control device to adjust the parameters of the pre-screening device, the crushing device and the screening device, so that the screening particle size and the screening efficiency are ensured, and the coal screening system device has the characteristics of high stability, high efficiency, high reliability and the like.

Description

technical field [0001] The invention belongs to the technical field of coal processing, and in particular relates to a coal screening system device and a screening method based on big data. Background technique [0002] Coal is one of the main energy sources for people's lives. In the process of coal mining, crushing, screening and drying of coal are essential operations. The smaller the coal, the higher the fullness of combustion. In the combustion furnace, the The size requirement of coal is relatively high, and it needs to be screened to meet the requirements of use. In the existing technology, coal is first crushed and then screened. The coal comes out of the crusher and is transported by belt to the vibrating screen for screening. This crushing and screening method takes a long time. , low efficiency and high cost, and in the prior art, the coal is uniformly fed into the crusher for crushing, but some coal in the raw coal is already finely crushed and does not need to b...
