Problems solved by technology

[0004] There are many steps in the preparation of coal samples, any error in any link will affect the quality of the sample preparation, and ultimately affect the test results
[0005] At present, the method of sample preparation in our country is to adopt the method of manual sample preparation, the procedure is complex, the labor intensity is high, the efficiency of sample preparation is low, and the confidentiality is poor. Therefore, the fundamental way out of sample preparation is to realize the automation and mechanization of the sample preparation process.

Abstract

The invention relates to an automatic sampling device, which comprises a sample collecting device, a crushing device, a reducing packing device, a sealing device, a control circuit and a belt conveyor. A coal sample is conveyed among the devices through the belt conveyor according to a time sequence, and the mechanical automatic treatment of the coal sample from sampling to sealing is completed; and therefore, man interference is reduced, work that cannot be done by a mechanical arm is done, residual samples are eliminated effectively, the sample nature is restored, and the sample data are more pure and scientific.

Description

technical field [0001] The invention relates to the field of fuel management in thermal power plants, in particular to the unmanned automatic sample preparation of coal samples, and completes the fully automatic mechanical processing of coal samples from sample preparation to packaging. Background technique [0002] Fuel management in thermal power plants is a complex system engineering, involving fuel ordering, procurement, loading and unloading, inspection and acceptance, vehicle management, cost settlement, coal blending and combustion, coal plant management, statistics, etc. With the changes in the operating environment faced by power generation companies, the original fuel management model of power generation companies can no longer meet the current requirements, and the management level needs to be improved urgently. Among them, the quality data of incoming coal is obtained through the process of mining, production and chemical process. These three processes are interr...
