Abstract

The invention discloses a double-layer ash cone multi-image acquisition device for a vertical intelligent ash melting tester, comprising a sealed corundum tube, a temperature insulating sleeve is arranged on the inner side of the lower side of the sealed corundum tube, and an instrument is arranged on the outer side of the lower side of the sealed corundum tube The partition, the bottom of the instrument partition is provided with a sealed heat insulation pad, the bottom of the sealed heat insulation pad is equipped with an upper fixing seat, and the inner side of the bottom of the upper fixing seat is provided with a fixing groove, and the inside of the fixing groove An upper taper sleeve is provided, and a lower taper sleeve is installed inside the upper taper sleeve, and a vertical lifting corundum tube is installed inside the lower taper sleeve. The invention can analyze the ash melting characteristics of 10 standard ash cones at one time, doubles the efficiency, saves half of the electric energy, and adopts a fixed structure, with better sealing performance, simpler structure, simple and easy assembly and disassembly , higher reliability, more able to simulate the actual working conditions of the furnace, and the restored ash fusion characteristics are more realistic.

Description

technical field [0001] The invention relates to the field of image acquisition devices, in particular to a double-layer ash cone multi-image acquisition device for a vertical intelligent ash fusion tester. Background technique [0002] The ash melting point is to detect the coal ash triangular cone of a certain size, heat it at a certain heating rate in a certain gas medium, observe the shape change of the ash cone during the heating process, observe and record four characteristic melting temperatures: DT (deformation temperature ), ST (softening temperature), HT (hemispherical temperature), FT (flow temperature). The determination of coal ash fusibility at home and abroad is based on GB / T219-2008, ISO540, ASTM1857 standards. Using advanced CCD camera technology, it can automatically complete the tracking of the whole test, and the artificial intelligence picture recognition technology liberates the human eyes and achieves the purpose of protecting the eyes. However, the v...

Problems solved by technology

[0004] The traditional ash melting point tester has vertical and horizontal types. The horizontal ash melting point is heated by silicon carbon tubes, which can be identified by human eyes. The requirements for manual identification and controllability are relatively high; the vertical ash melting point uses silicon molybdenum rods, which has the advantage of heating temperature High, long constant temperature zone, accurate temperature rise control, high degree of intelligence, the disadvantage is that the ash cone is easy to dump during the rotation of the sample, and the positions change alternately, and the ash cone starts, rotates, and stops at a certain speed under high temperature , the increased external force acts on the gray cone, so that there is a certain gap between the deformation of the gray cone and the real deformation process
