Description

Ash fusibility test mechanism

Technical Field

The utility model relates to a coal quality detection and analysis technical field especially refers to an ash fusibility accredited testing organization.

Background

The ash fusion testing instrument is used for detecting the fusibility of the coal sample ash cone, the fusibility of the ash cone is directly related to whether a power plant boiler is sintered or not and the severity of sintering, and the influence on the safe use of the boiler, a cement vertical kiln and the like is great. In the ash fusion tester in the prior art, an ash cone sample is arranged on a supporting plate, and the supporting plate is arranged on a supporting cup. In the testing process, the supporting cup drives the supporting plate to rotate, so that the ash cone sample rotates in the constant-temperature area of the high-temperature furnace tube and is heated by uniform temperature rise until the ash cone of the coal sample reaches a molten state. In the process, the shooting mechanism shoots and captures images in real time, and the temperatures of four characteristic points of deformation, softening, hemisphere and flowing of the coal sample are obtained through computer or manual analysis.

In the existing ash fusion tester, an image taking tube is arranged on one side of a furnace tube close to a camera, a background tube is arranged on one side opposite to the image taking tube, and a cavity of the background tube effectively prevents light reflection to form a dark background which is obviously different from a sample, a surrounding supporting plate and the furnace tube so as to facilitate the effective identification of the sample by the camera. However, in order to ensure that only one sample is shot by the camera during one-time image taking, the existing ash fusion tester needs to shoot one sample far away from the camera through the gap between two samples close to one side of the camera, so that the lofting quantity is limited. At present, only 5 national standard samples can be placed on an ash cone supporting plate with the diameter of 60mm in the market theoretically, the utilization rate of the ash cone supporting plate is low, more than 5 hours are needed for each test, and the test efficiency of a single experimental sample is low.
