Detection method for coal ash fusion tester

Abstract

The invention discloses a detection method for a coal ash fusion tester. The detection method comprises the following steps: regulating the relative positions of a tray, an index plate, a video cameraand a detector to enable a corresponding ash cone to continue to rotate by a preset angle to reach the vision preset position of the video camera when the detector detects the passing of each index hole; controlling the tray and the index plate to synchronously rotate uniformly, vertically arranging a rotating axis, and enabling the rotating axis to coincide with a central axis of the index plate; controlling the video camera to start continuously acquiring images each time the detector detects the passing of one index hole, controlling the video camera to stop acquiring the images after theash cone reaches the vision preset position, controlling the video camera to starting continuously acquiring images again until the detector detects the passing the next index hole, and controlling the video camera to stop acquiring the image after the ash cone reaches the vision preset position. The ash cone in the image is guaranteed to be located on the vision preset position of the video camera, the shooting accuracy is improved, the image recognition is facilitated, and the maintenance times are reduced.

Description

technical field [0001] The invention relates to the field of coal ash detection, in particular to a detection method of a coal ash melting tester. Background technique [0002] In the coal quality analysis industry, the melting property of coal ash is a very important physical property, which is directly related to whether the power plant boiler is ligated and its severity, and has a great impact on the safe use of boilers, cement shaft kilns, etc. Sexual testing is very necessary. At present, a coal ash melting tester is generally used to measure the melting characteristics of coal ash. According to the requirements of the test method for coal ash melting, coal ash needs to be made into a triangular cone of a certain size, and after drying, it is placed in the constant temperature zone of the main furnace tube, and the atmosphere required for the test is passed into or formed in the furnace tube, and the temperature is increased at a certain rate. Raise the temperature, o...

Problems solved by technology

Since the ash cone needs to be heated to 1600°C, and because the support plate and furnace core are all made of corundum, the fit gap between them is too large, and deformation will occur at high temperature, resulting in differences in the positioning of each experiment. So often need to maintain the location
