3mm coal sample milling and packaging integrated equipment and method thereof

Abstract

The invention relates to 3mm coal sample milling and packaging integrated equipment and a method thereof. Current scientific research institutions, coal quality testing units, etc. commonly face the difficulty in large-scale milling work of 3mm coal samples. The invention is characterized in that the equipment comprises a disassembling sampling system, a coal sample milling system, a packaging encoding system and dust removal systems. The disassembling sampling system and the coal sample milling system are connected. The coal sample milling system and the packaging encoding system are connected. The dust removal systems are arranged around disassembling sampling system, around the coal sample milling system and around the packaging encoding system. After milling and packaging, a packaged and encoded 0.2mm general analytical testing coal sample and a packaged and encoded 3mm coal sample for back-check can be obtained, and corresponding sample marks, sample QR codes and sample preparation record lists are printed.

Description

technical field [0001] The invention relates to an integrated equipment and method for 3mm coal sample pulverization and encapsulation, which is mainly used in the unattended and efficient sample preparation of 3 mm coal samples for general analysis and test coal samples (coal powder particle size is below 0.2 mm). It can be expanded and applied to other milling fields. Background technique [0002] At present, in the field of coal quality inspection, the 0.2 mm general analysis test coal sample is usually prepared from the 3 mm coal sample. When relevant scientific research institutes and coal quality inspection units carry out coal quality inspection work, they generally prepare 3mm coal samples at the site of coal-fired power generation enterprises, or directly extract 3mm coal samples from coal-fired power generation enterprises for inspection, and then send them to coal quality inspection. The laboratory prepared a 0.2 mm general analysis test coal sample, and finally ...

AI Technical Summary

Problems solved by technology

[0003] The 3 mm coal sample has brought difficulties to the quality inspection of coal samples due to the large number of companies involved, large quality differences, and inconsistent packaging.

Nowadays, the preparation of 0.2 mm general analysis test coal samples usually adopts a sealed sample preparation pulverizer. The whole process of sample preparation generally has problems such as heavy workload, cumbersome feeding, difficult collection of powder samples and easy to fly dust.

The existing unattended sample preparation system is mainly aimed at the sample preparation of coal samples with a particle size greater than 6 mm in coal-fired enterprises. Due to the long drying process, the sample preparation efficiency is far from meeting the large-scale pulverization work of 3 mm coal samples. , and there are common problems that the samples need to be cleaned for pulverization, the coal samples are not cleaned cleanly, and the representativeness cannot be guaranteed
