Device and method for monitoring coal quality

Abstract

The invention discloses a device and a method for monitoring coal quality; the device comprises a system control module, a coal-carrying vehicle RFID vehicle number automatic identification device, and a sampling sample-preparing chemical examination device; the sampling sample-preparing chemical examination device is a device for integrated continuous process operations of sampling, sample preparation, and chemical examination. The method comprises the following steps: when a coal-carrying vehicle enters a factory, performing vehicle coal-carrying information input before sampling, performing vehicle-arrival sampling, performing vehicle sampling by a mechanical sampler, allowing residual coal in the mechanical sampler to enter a coal quality on-line rapid monitoring analyzing device, performing coal quality on-line rapid monitoring analysis, and displaying monitoring results. The excellent effects of the invention are that: unqualified coal is thoroughly prevented from entering the factory; qualified coal is stored by stacks based on the quality; the coal is blended by the coal entering the factory; the results of laboratory experiment are monitored; disputes between enterprises and coal suppliers are reduced; the qualified rate of the coal entering the factory is reduced from 75% to 0%.

Description

field of invention [0001] The invention relates to a monitoring device and method, in particular to a device and method for monitoring coal quality. Background technique [0002] In enterprises that use coal as the main energy or raw material, coal accounts for 60%-75% of the total operating costs of enterprises, and accounts for 80% of variable costs. With the development of our country's economy, the supply and demand relationship between various enterprises that use coal as the main energy or raw material and coal suppliers under the original planned economy has changed, and has transformed into a structural form in which coal suppliers dominate the market position. In pursuit of higher profits, Dakuang Coal exported high-quality coal. In order to reduce costs, enterprises that use coal as their main energy source or raw material, such as thermal power plants, coal chemical companies, chemical plants, and steel plants, purchase more coal from small kilns. It is also dif...
