An unattended intelligent sample preparation device and method for a thermal power plant

Abstract

The invention discloses an unattended intelligent joint sample preparation device for a thermal power plant, which includes: a jaw crusher and a sample packaging machine; wherein the jaw crusher includes: a jaw crusher body, a feeding pipe, an upper A sealing cover and a double-roll mill, wherein the double-roll mill is set in the jaw crusher body; the upper sealing cover is connected with an air pump and a cleaning water pump; the feeding pipe is provided with a movable The waste absorbing device is arranged on the side of the jaw crusher feeding pipe to absorb waste; wherein, the feeding pipe of the jaw crusher is connected to the filling port of the sample packaging machine; the packaging machine includes the sample packaging machine body , and a sample recorder, a sample packaging bag, and an electronic weighing scale; each sample packaging bag is provided with an information barcode. The invention can fully realize the process from sample preparation to packaging through machinery, reducing human interference factors; and can effectively remove residual samples and restore the essence of samples, making sample data more pure and scientific.

Description

technical field [0001] The invention relates to the technical field of automatic sample preparation in thermal power plants, in particular to an unattended intelligent sample preparation device and method for thermal power plants. Background technique [0002] Fuel management in thermal power plants is a complex system engineering, involving a series of tasks such as fuel ordering, procurement, loading and unloading, inspection and acceptance, vehicle management, cost settlement, coal blending and combustion, coal plant management, and statistics. With the changes in the foreign thermal coal market and 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. [0003] Among them, the quality data of incoming coal is obtained through the process of mining, production and chemical process. These three process...
