Background
The ash fusion point is a coal ash triangular cone which detects a certain size, and is heated at a certain heating rate in a certain gas medium, the morphological change of the ash cone in the heating process is observed, and four characteristic fusion temperatures are observed and recorded: DT (deformation temperature), ST (softening temperature), HT (hemispherical temperature), FT (flow temperature). The measurement of the coal ash meltability at home and abroad is according to the GB/T219-2008, ISO540, ASTM1857 standard. The tracking of the whole test process is automatically completed by utilizing an advanced CCD camera shooting technology, and the artificial intelligent picture recognition technology liberates the eyes of people and achieves the purpose of protecting the eyes. However, the vertical ash fusibility tester adopts a triangular cone rotating mechanism at present, so that the problems of eccentricity, inclination and the like of an ash cone are easily caused, and when HT and FT temperatures are very close, the image acquisition is lost due to the fact that the image can be acquired again only by rotating for one circle, and the detection precision is influenced.

The traditional ash melting point tester has a vertical type and a horizontal type, the horizontal type ash melting point adopts a carbon silicon tube for heating, the horizontal type ash melting point is distinguished by naked eyes, and the requirement on manual identification and the controllability are high; the vertical ash melting point adopts a silicon-molybdenum rod, and has the advantages of high heating temperature, long constant temperature zone, accurate temperature rise control and high intelligent degree, and the defects that an ash cone is easy to topple over in the rotating process of a sample, all positions are changed alternately, the ash cone is started, rotated and stopped at a certain speed in a high-temperature state, and increased external force acts on the ash cone, so that certain difference exists between the deformation of the ash cone and the real deformation process. The time interval of one circle of the gray cone is 34 seconds by a stopwatch, the heating rate is controlled to be 1 minute and 5 ℃, and the result is calculated as follows: the temperature rise of the ash cone in one turnover is 2.83 ℃. When the coal ash with low melting point (within 3 ℃) meets the error, the automatic identification error is easy to occur at HT (hemispherical temperature) and FT (flow temperature). For solving this problem, promote the degree of accuracy of domestic ash melting point tester, this project has researched and developed a high efficiency integration intelligence ash melting tester, this instrument adopts double-deck fixed ash awl, two-layer about the ash awl holds in the palm design, every layer is 5 coal samples side by side, 10 total (the trade leads), simultaneously gather data together, need not rotate and gather alone, guaranteed that every image all gathers figure change in real time at any period, this vertical double-deck fixed ash awl many image acquisition method belongs to domestic trade initiative.
