Multifunctional rotary type drying system and method for automated operation

Abstract

The invention relates to a multifunctional rotary type drying system and method for automated operation. The drying system comprises a box body, a material conveying unit, a power unit, a discharging unit and a control unit. According to the method, drying operation is carried out by utilizing the system. The multifunctional rotary type drying system and method for the automated operation can achieve continuous automatic drying of a large number of materials.

Description

technical field [0001] The invention relates to the field of coal sample detection, in particular to a multifunctional rotary drying system and method for automatic operations. Background technique [0002] In the coal industry, there will be a procedure for drying coal samples during the sampling process. At present, coal samples are generally dried in the industry by manually sending them into the drying device, setting the drying time, and waiting for the drying to complete. Finally, it is manually taken out from the drying box again, and then the coal quality test is carried out. [0003] In this process, staff are always required to record the drying time of coal samples. Usually the staff is used to drying multiple coal samples at the same time, and completes the testing of all coal samples in a short time after the drying is completed. When the number of coal samples increases slightly, there is a great risk of mixing samples by artificially controlling the drying p...

AI Technical Summary

Problems solved by technology

When the number of coal samples increases slightly, there is a great risk of mixing samples by artificially controlling the drying process. At the same time, it is difficult for the staff to complete the simultaneous analysis of multiple coal samples in a short period of time. Therefore, there will always be some coal samples that will absorb the moisture in the air again, thus violating the original intention of drying the coal samples

[0004] In addition, this method of artificially controlling the drying process still has the following problems: firstly, human operation is likely to cause loss of coal samples and affect the representativeness of coal samples; secondly, manual operation requires workers to be exposed to coal dust. It has a certain impact on the health of the staff; third, due to the normal work and rest rules of people and the legal work system, it is difficult for human operation to strictly meet the requirements of sampling at any time, preparing samples at any time, drying at any time, and testing at any time, that is, online operations. To a certain extent, it also has an impact on the representativeness of coal quality. If this is done, it will definitely have a great impact on the work and rest rules and physical health of the staff; fourth, it is difficult to avoid the possibility of artificially maliciously changing coal samples.
