Description
Technical field
It is more with the double-deck ash cone that the present invention relates to image collecting device fields more particularly to upright intelligent ash fusion tester
Image collecting device.
Background technology
Ash fusion point is to detect the coal ash pyrometric cone of certain size, in certain gas medium, with certain heating rate
Heating observes metamorphosis of the ash cone in thermal histories, observes and records four feature melting temperatures：DT (deformation temperature),
ST（Softening temperature）、HT（Hemispherical fusion temperature）、FT（Flowing temperature）.It is both at home and abroad according to GB/T219- for coal ash melting property measurement
2008, ISO540, ASTM1857 standard.Using advanced CCD photography technologies, it is automatically performed the whole tracking of experiment, Er Qieren
Work intelligence picture identification technology has liberated the eyes of people, reaches protection eyes purpose.But vertical ash fusion tester, mesh
It is preceding all to use pyrometric cone rotating mechanism, the problems such as being easy to cause ash cone bias, tilt, when HT, FT temperature are close, due to needing
Image could be acquired again by rotating a circle, and Image Acquisition is caused to lack, and influence accuracy of detection.
Current many colleges and universities of section and scientific research institution both at home and abroad, such as Sichuan University, China Engineering Physics Research Institute, Chinese science
Institute's Shanxi coal chemistry institute etc. using using thermomechanical analyzer (TMA) to coal ash carry out ash fusibility testing research,
But still in conceptual phase, normal use is not put into largely.
Traditional ash fusion point tester has vertical with horizontal, and horizontal ash fusion point is heated using carborunbum tube, and artificial naked eyes distinguish, right
Artificial identification requires and handling relatively high；It is heating temperature height, zone of constant temperature that vertical ash fusion point, which uses Si-Mo rod, advantage,
Long, temperature rises precise control, and intelligence degree is high, the disadvantage is that sample ash cone in rotation process is easy to topple over, each position alternately changes
Become, and ash cone is also started with certain speed at high operating temperatures, rotation, is stopped, increased external force acts on ash cone so that
With true deformation process, there are a certain distance for the deformation of ash cone.Rotating the time interval that one encloses by manual time-keeping ash cone is
34 seconds, heating rate control for 1 minute 5 DEG C, it is thus calculated the result is that：Ash cone has enough to meet the need primary temperature and is upgraded to 2.83 DEG C.Such as
Encounter low melting point（Error within 3 DEG C）Coal ash is easy in HT（Hemispherical fusion temperature）、FT（Flowing temperature）There is automatic identification mistake in point
Accidentally.To solve this problem, the accuracy of domestic ash fusion point tester is promoted, this project has developed a High-efficiency integral intelligence
Can ash melting tester, the instrument is using the double-deck fixed ash cone, ash cone support design upper layer and lower layer, and every layer of 5 coal sample side by side amounts to
10（Industry-leading）, while gathered data together, do not have to rotation individually acquisition, ensure that each image exists at any period
Acquisition graphic change in real time, it is pioneering that the more image-pickup methods of this vertical double fixation ash cone belong to domestic industry.
