Abstract

The invention discloses an ash fusibility testing instrument capable of automatically conveying and taking samples, which comprises a high temperature furnace, an ash cone supporting plate, a graphite cup, an image taking mechanism and a control mechanism, wherein an alundum tube is arranged in the high temperature furnace; the ash cone supporting plate and the graphite cup are placed in the alundum tube; a box body is arranged below the high temperature furnace; an automatic sample conveying mechanism is arranged in the box body; the automatic sample conveying mechanism comprises a sample conveying rod, a lifting drive component and a translation drive component; the sample conveying rod is fixed on the lifting drive component; the lifting drive component is fixed on the translation drive component; a sample conveying opening which is arranged on the high temperature furnace and is used for the sample conveying rod to pass through is positioned right below the alundum tube; and a sample connection which is used for the sample conveying rod to pass through is arranged at the top of the box body. The ash fusibility testing instrument capable of automatically conveying and taking the samples, which is provided by the invention, has the advantages of simple and compact structure, low cost, high degree of automation and high overall efficiency.

Description

technical field [0001] The invention mainly relates to the field of coal sample measuring equipment, in particular to an ash fusion tester. Background technique [0002] The melting characteristics of coal ash are directly related to whether slagging (commonly known as coking) and its severity in power plant boilers, so it has a great relationship with the safe and economical operation of boilers. In the prior art, an ash melting tester is generally used to measure the ash melting property of a coal sample. At present, the existing ash melting tester includes a high-temperature furnace, an ash cone support, a graphite cup, an imaging mechanism, and a control mechanism. The ash cone of the coal sample to be tested is placed on the ash cone support and completed in a high-temperature furnace. Heating, the image signal of the ash cone at each temperature is collected by the imaging mechanism, so as to automatically or manually judge the melting temperature of the four fevers o...
