Automatic coal density testing system and method

Abstract

The invention relates to an automatic coal density testing system which comprises a sampler, a metering unit, a water replenishing unit and a discharge unit, wherein the sampler and the water replenishing unit are arranged beside the metering unit and are respectively used for feeding a coal sample and replenishing water into the metering unit; the discharge unit is arranged on one side of the metering unit and is used for discharging the coal sample and the water in the metering unit. Due to adoption of the sampler, the metering unit, the water replenishing unit and the discharge unit of theautomatic coal density testing system, automatic measurement on the density of the coal sample is achieved, problems that a conventional automatic coal density testing system is difficult in sampling,tedious in measurement, high in cost, large in labor and time consumption, low in measurement precision, and the like, are solved, a measurement system which is low in cost and convenient and precisein measurement is provided for large coal use companies such as heat-engine plants and heat supply companies, the companies can handle real-time density of fuel coal conveniently, and coal quality can be conveniently controlled and detected.

Description

technical field [0001] The invention relates to the technical field of coal chemical industry, in particular to a system and method for automatically measuring coal density. Background technique [0002] The density of coal can reflect the quality of coal to a certain extent. For large-scale coal-consuming units such as thermal power plants and heating companies, mastering the real-time density of fuel coal can help control and detect coal quality. [0003] At present, most enterprises use the method of intermittent sampling measurement to estimate the density of coal piles. This method is difficult to take samples, and the measurement data has great randomness, which cannot accurately reflect the real density of fuel coal in real time. In addition, this kind of method The method completely relies on manual operation, and the measurement efficiency is very low. Contents of the invention [0004] Based on this, the object of the present invention is to provide a system for...

AI Technical Summary

Problems solved by technology

[0006] The automatic coal density measurement system of the present invention realizes the automatic measurement of the coal sample density by setting a sampler, a metering unit, a water supply unit and a discharge unit, and solves the difficulty in sampling, cumbersome measurement, high cost, and high cost of existing coal density measurement methods. For the problems of large labor time consumption and low measurement accuracy, a low-cost and convenient and accurate measurement system is provided for large coal-consuming units such as thermal power plants and heating enterprises, which is convenient for enterprises to grasp the real-time density of fuel coal and helps to control and detect coal quality
