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, the temperature of the background tube is low, and the brightness of the background tube is limited at low temperature, so that the background tube is different from a sample, a surrounding supporting plate and a relatively dark background of the furnace tube and is used for identifying the sample by the camera. However, the ash fusion tester in the prior art still has the following disadvantages:

1. the temperature of the background tube is gradually reduced from the position close to the gray cone to the position far away from the end of the gray cone, so that the contrast of the relative brightness of the background tube, the sample, the surrounding supporting plate and the furnace tube is basically almost the same as the color brightness, a relatively dark background is formed, and the identification precision of the camera is reduced.

2. The arrangement of the background tube leads to the complicated design of the furnace tube and the reduction of the reliability.
