Ash fusibility tester and image capturing method thereof

Abstract

The invention relates to the technical field of coal quality detection analysis, and in particular relates to an ash fusibility tester and an image capturing method thereof. The ash fusibility tester comprises a high temperature furnace, a furnace tube, a background plate, an image capturing component and a disc-shaped ash cone supporting plate as well as a light source arranged outside the furnace tube, wherein the furnace tube is arranged in the high temperature furnace, the ash cone supporting plate is arranged in the furnace tube, and a rotating mechanism used for driving the ash cone supporting plate to rotate in the furnace tube is arranged below the ash cone supporting plate; the image capturing component is used for obtaining an image of an ash cone on the ash cone supporting plate; the background plate is arranged at the middle part of the ash cone supporting plate, the upper edge of the background plate is connected with the top of the furnace tube, the lower edge of the background plate is arranged below the upper surface of the ash cone supporting plate, and the background plate is made from a transparent material; and light rays emitted from the light source are ejected from one side, far away from the image capturing component, of the background plate and then pass through the background plate. The ash fusibility tester provided by the invention has high testing efficiency, and the furnace tube is simple in structure.

Description

Technical field [0001] The invention relates to the technical field of coal quality detection and analysis, in particular to an ash fusibility tester and an imaging method thereof. Background technique [0002] The ash fusion test instrument is an instrument used to detect the melting of the ash cone of coal samples. The melting of the ash cone is directly related to whether the power plant boiler has sintering and the severity of sintering, which has a great impact on the safe use of boilers and cement shaft kilns. . In the current ash fusion tester, the coal sample ash cone is arranged on a supporting plate, and the supporting plate is fixed on the supporting cup. During the test, the support cup drives the support plate to rotate, so that the coal sample ash cone rotates in the constant temperature zone of the high-temperature furnace tube to uniformly heat up and heat until the coal sample ash cone reaches a molten state. In this process, the camera mechanism takes real-tim...
