Problems solved by technology

Obviously, this detection method based on manual experience is inaccurate. Different people have different measurement results. Even the same person will get different measurement results under different emotions; at the same time, the manual detection results cannot be directly measured. Data transmission and real-time control of the conveying speed of the raw coal conveying mechanism
It is not suitable for the needs of modern industrial automation production

Abstract

The invention relates to a device for detecting the layered condition of a raw coal mixture, which is characterized by comprising a central processor (1), a regulated power supply (2), a display (3), at least two detection units and an I / O (Input / Output) interface (4) for outputting a control signal to a raw coal conveying mechanism, wherein the regulated power supply (2), the display (3), the I / O interface (4) and the detection units are all connected with the central processor (1); each detection unit comprises a filter, a pre-amplifier and an electronic sensor bar for automatically detecting vibration quantity in a coal bed; the filter, the pre-amplifier and the electronic sensor bar are sequentially connected; and the filter is connected with the central processor (1). The invention provides the device for detecting the layered condition of the raw coal mixture, which has an accurate detection result and high detection efficiency and can carry out real-time control on the conveying speed of the raw coal conveying mechanism according to the detection result.

Description

technical field [0001] The invention relates to a detection device used in automatic production of coal mines, in particular to a device for detecting the layering status of raw coal mixture. Background technique [0002] In coal washing (coal washing is an indispensable process of coal deep processing, the coal directly mined from the mine is called raw coal. The raw coal is mixed with many impurities during the mining process, and the quality of the coal is also different. The internal ash content is small and the internal ash content is large. Coal is mixed together. Coal washing is an industrial process that removes impurities in raw coal, or classifies high-quality coal and inferior coal. The products produced after the coal washing process are generally divided into gangue, medium coal, B-grade clean coal, Class A clean coal, the finished coal after the coal washing process is usually called clean coal. Through coal washing, the cost of coal transportation can be reduc...
