Abstract

The invention relates to the technical field of coal quality detection and analysis, and in particular relates to an ash fusibility tester and an image taking method thereof. The ash fusibility tester comprises a high temperature furnace, a furnace tube, a background plate, an image taking assembly and a disc-shaped ash cone supporting plate, 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 for driving the ash cone supporting plate to rotate in the furnace tube is arranged below the ash cone supporting plate; the image taking assembly is used for acquiring an image of an ash cone on the ash cone supporting plate; the background plate is disposed in 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 disposed below the upper surface of the ash cone supporting plate, the background plate is a mirror-face reflection device, a reflection surface of the background plate faces a low temperature area of the furnace tube, and the image taking assembly faces a reflection end of the reflection surface of the background plate. By adopting the ash fusibility tester, the test efficiency is increased, 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 fusion tester and an imaging method thereof. Background technique [0002] The ash melting test instrument is an instrument used to detect the melting of the ash cone of the coal sample. The melting of the ash cone is directly related to whether there is sintering in the boiler of the power plant and the severity of the sintering, and has a great impact on the safe use of boilers and cement shaft kilns. . In the current ash melting tester, the coal sample ash cone is arranged on the support plate, and the support plate is fixed on the support cup. During the test, the support cup drives the supporting plate to rotate, so that the coal sample ash cone rotates in the constant temperature zone of the high-temperature furnace tube and heats up evenly until the coal sample ash cone reaches a molten state. During this process, the camera mechanism t...
